Many of us are thinking about the changes we want to make this year. For some, these changes will be financial; for others, physical or spiritual. But for all of us, there are important resolutions we can make to "green" our lives. Although this is often a subject focused on by industrialized nations, people in developing countries can also take important steps to reduce their growing environmental impact.

"We in the developing world must embark on a more vigorous 'going green' program," says Sue Edwards, Director of the Institute for Sustainable Development (ISD). "As incomes rise and urbanization increases, a growing middle class must work with city planners to ensure our communities are sustainable."

ISD's Tigray Project recently received the Gothenburg Award for Sustainable Development 2011, shared with Kofi Annan, Chairman of the Alliance for a Green Revolution in Africa (AGRA). Since 1996, Tigray has worked to help Ethiopian farmers rehabilitate ecosystems, raise land productivity, and increase incomes through such practices as composting, biodiversity enhancement, the conservation of water and soil, and the empowerment of local communities to manage their own development.

Broadening sustainability efforts is essential to solving many of the world's challenges, including food production, security, and poverty. The United Nations has designated 2012 as the International Year of Sustainable Energy for All.

Hunger, poverty, and climate change are issues that we in the developing world can help address. Here are 12 simple steps to go green in 2012:

As we head into 2012, many of us will be resolving to lose those few extra pounds, save more money, or spend a few more hours with our families and friends. But there are also some resolutions we can make to make our lives a little greener. Each of us, especially in the United States, can make a commitment to reducing our environmental impacts.

The United Nations has designated 2012 as the International Year of Sustainable Energy for All. Broadening access to sustainable energy is essential to solving many of the world's challenges, including food production, security, and poverty.

Hunger, poverty, and climate change are issues that we can all help address. Here are 12 simple steps to go green in 2012:

World grain production fell in 2010, exacerbating a global food situation already plagued by rising prices, according to new research published by the Worldwatch Institute for its Vital Signs Online publication. Despite record rice and maize yields around the world, global wheat production dropped substantially enough to bring total grain output to just below 2008 levels.

Maize, wheat, and rice provide nearly two-thirds of the global human diet and serve as critical inputs for both animal feed and industrial products. The significance of these crops guarantees that a decline in production will produce ripple effects throughout the global economy, particularly as increased food prices continue to take a toll on the world's neediest populations. Overall, rice and wheat production have tripled since the 1960s, and maize production has quadrupled, despite global acreage of these crops increasing by only 35 percent.

Production increased worldwide, but there was greater reliance on irrigation, synthetic fertilizers, and pesticides--all of which take resources, can be costly, and may cause substantial environmental degradation. As farmers have begun to witness these impacts, many have been forced to abandon their fields because of infertile soil.

Nevertheless, preliminary data for 2011 indicate that grain production is recovering from the 2010 slump. The United Nations Food and Agriculture Organization (FAO) recently forecast that cereal output in 2011-12 will be 3 percent higher than in 2010-11.

Grain remains the foundation of the world's diet, and the failure of harvests in recent years to keep pace with growth in meat consumption and population is worrisome. It's important that we identify and implement more inventive and sustainable strategies in grain production. Reducing the proportion of grain harvests lost to weather disasters and waste or diverted for corn ethanol production and animal feed is among such strategies. It's also important that we prioritize grain availability for those who need it most.

Recent growth in agricultural production has been uneven. In many regions, climate change has brought irregular weather patterns such as rising temperatures, violent storms, and flash flooding. In Russia, where severe drought has plagued large farming regions, overall wheat yields plunged 40 percent in 2010, compared to a decline of only 5 percent worldwide. Subsequently, Russia--the fourth largest wheat exporter in 2009--banned all wheat exports, severely disrupting world grain markets. Poor weather took its toll elsewhere as well: El Niño in the west Pacific, for example, brought rice production down significantly in the Philippines, already the world's largest food importer.

Rising demand for ethanol fuel, which in the United States is produced almost exclusively from corn feedstock, is having an impact on grain prices as well. According to the U.S. Congressional Budget Office (CBO), about 20 percent of the increase in maize prices between 2007 and 2008 was due to domestic ethanol demand. Demand for grains is also rising in countries such as China and India, where growing middle classes are adopting more diverse diets.

Farming has always been an uncertain business that depends in large part on the weather, and it could be entering an even more difficult phase. As the global climate changes, the warmer, less stable atmospheric conditions could be detrimental for food production. In an already fragile economy, continued volatile prices and unpredictable weather-induced shortages are sure to negatively affect both producers and consumers in developing countries.

Further highlights from the research:

• Between 1960 and 2010, annual global grain production increased from 643 million tons to 2.2 billion tons.


• U.S. maize (corn) production was down 5 percent in 2010 due to drought in the east and excessive rain in the west. The United States is the world's largest exporter of maize, accounting for 56 percent of global exports from 2006 to 2010.


• According to the FAO's Cereal Price Index (CPI), which uses 2002-04 prices for wheat, rice and maize as its baseline (100), food prices increased to an index level of 185 in August 2010 and set a record at 265 in April 2011.


• Forty percent of the global increase in maize prices in 2000-07 was due to worldwide demand for ethanol, according to the International Food Policy Research Institute. Additional reasons for the jump in food prices include the weakening of the U.S. dollar, speculation on grain prices, and possible climate change impacts.


• Stanford University researchers who created a model to determine how changing weather patterns affect crop yields found a 2.9 percent increase in global rice production as a result of greater precipitation, but losses of 3.8 percent for wheat and 2.5 percent for maize.

Interest in high-speed rail (HSR) is growing around the world and the number of countries running these trains is expected to nearly double over the next few years, according to new research by the Worldwatch Institute for Vital Signs Online. By 2014, high-speed trains will be operating in nearly 24 countries, including China, France, Italy, Japan, Spain, and the United States, up from only 14 countries today. The increase in HSR is due largely to its reliability and ability to cover vast geographic distances in a short time, to investments aimed at connecting once-isolated regions, and to the diminishing appeal of air travel, which is becoming more cumbersome because of security concerns.

The rise in HSR has been very rapid--in just three years, between January 2008 and January 2011, the operational fleet grew from 1,737 high-speed trainsets worldwide to 2,517. Two-thirds of this fleet is found in just five countries: France, China, Japan, Germany, and Spain. By 2014, the global fleet is expected to total more than 3,700 units.

Not only is HSR reliable, but it also can be more friendly than cars or airplanes. A 2006 comparison of greenhouse gas emissions by travel mode, released by the Center for Neighborhood Technologies, found that HSR lines in Europe and Japan released 30-70 grams of carbon dioxide per passenger-kilometer, versus 150 grams for automobiles and 170 grams for airplanes.

Although there is no universal speed definition for HSR, the threshold is typically set at 250 kilometers per hour on new tracks and 200 kilometers per hour on existing, upgraded tracks. The length of HSR tracks worldwide is undergoing explosive growth in order to meet increasing demand. Between 2009 and 2011, the total length of operational track has grown from some 10,700 kilometers to nearly 17,000 kilometers. Another 8,000 kilometers is currently under construction, and some 17,700 kilometers more is planned, for a combined total of close to 43,000 kilometers. That is equivalent to about 4 percent of all rail lines--passenger and freight--in the world today.

By track length, the current high-speed leaders are China, Japan, Spain, France, and Germany. Other countries are joining the high-speed league as well. Turkey has ambitious plans to reach 2,424 kilometers and surpass the length of Germany's network. Italy, Portugal, and the United States all hope to reach track lengths of more than 1,000 kilometers. Another 15 countries have plans for shorter networks.

But in Europe, France continues to account for about half of all European high-speed rail travel. HSR reached an astounding 62 percent of the country's passenger rail travel volume in 2008, up from just 23 percent in 1990, thanks to affordable ticket prices, an impressive network, and reliability. And in Japan, the Shinkansen trains are known for their exceedingly high degree of reliability. JR Central, the largest of the Japanese rail operating companies, reports that the average delay per high-speed train throughout a year is just half a minute. On all routes in Japan where both air and high-speed rail connections are available, rail has captured a 75 percent market share.

Further highlights from the research:

*    A draft plan for French transportation infrastructure investments for the next two decades allocates 52 percent of a total of $236 billion to HSR.
*    In 2005, the Spanish government announced an ambitious plan for some 10,000 kilometers of high-speed track by 2020, which would allow 90 percent of Spaniards to live within 50 kilometers of an HSR station.
*    Currently, China is investing about $100 billion annually in railway construction. The share of the country's railway infrastructure investment allocated to HSR has risen from less than 10 percent in 2005 to a stunning 60 percent in 2010.
*    Intercity rail in Japan accounts for 18 percent of total domestic passenger-kilometers by all travel modes--compared with just 5 to 8 percent in major European countries and less than 1 percent in the United States.
*    In France, rail's market share of the Paris-Marseille route rose from 22 percent in 2001 (before the introduction of high-speed service) to 69 percent in 2006. In Spain, the Madrid-Seville rail route's share rose from 33 to 84 percent.

Hamburgers, pizzas, french fries, and sugary drinks-in today's fast-paced world, these foods have become staples for many Americans. But this unhealthy diet has led to an increase in chronic health problems such as obesity, diabetes, heart attacks, strokes, and high blood pressure. According to the U.S. Centers for Disease Control and Prevention, nearly 34 percent of adults and 17 percent of children and adolescents are now obese, staggering numbers that the organizers of Food Day, a nationwide event taking place on October 24, hope to decrease dramatically.

But promoting safe, healthy and affordable food is only one aim of Food Day, which is sponsored by the Center for Science in the Public Interest, a nonprofit watchdog group that fights for food labeling, better nutrition, and safer food. The organizers also want to support sustainable, humane farming, and fair trading conditions.

Around the United States, cities and communities are coming together to showcase the benefits of eating healthy, locally grown, and organic food. Philadelphia is organizing a city-wide event focused on ending hunger and food "deserts"-areas where healthy, affordable food is difficult to obtain. In California, organizations are building a statewide Food Day partnership to promote new food policies, and in Iowa, conferences are being held to highlight how small and mid-sized farmers can get their produce to markets.

In addition to these forums and celebrations, nearly 400 individual events are being sponsored by communities, groups, and companies across the United States. These include:

• San Francisco. The organization savenature.org is hosting benefit dinners on October 20-22 to show how delicious earth-friendly food can be.

   
• Boston. Boston Food Swap is organizing a crowd-sourced potluck-where they will provide the venue, and attendees will provide local, organic food to show that responsible food is both nutritious and tasty.

   
• Phoenix. In a "Lunch and Learn" session for students and the general public, a panel of local farmers and chefs will demonstrate how they work together to provide sustainable food.

   
• Miami. The city will hold its annual Food & Recreation Expo, offering health screenings, fitness demos, diet and nutrition sessions, giveaways, free massages, and more. The host of "Dinner: Impossible," Robert Irvine, will perform a live cooking demonstration.

   
• Seattle. On October 24, the restaurant Fresh Starts and filmmaker Severine von Tscharner Fleming will screen "The Greenhorns," a film about the spirit, vision, and stories behind new farmers, followed by an interactive information session on the Farm Bill.

   
• Universities. Events are being planned at the University of Vermont, University of Pennsylvania, University of Minnesota, University of North Carolina, New York University, Stanford, Yale, and Harvard School of Public Health, among others.

The volatility of food prices, in particular price upswings, represents a major threat to food security in developing countries and typically affects poor populations the hardest. According to the World Bank, during 2010-11 rising food costs pushed nearly 70 million people worldwide into extreme poverty.

World Food Day is a global event designed to increase awareness and understanding and to create year-round action to alleviate hunger. Since 1981, the event has been observed on October 16 in recognition of the founding of the United Nations Food and Agriculture Organization (FAO), a specialized agency that was established in Quebec City, Canada, in 1945. This year's World Food Day theme is "Food prices - crisis to stability," with the purpose of shedding some light on this trend and what can be done to mitigate its impact on the most vulnerable.

Since the inception of World Food Day, organizations have taken advantage of the occasion to inform the public about what they can do to help end world hunger. Although the number of undernourished people worldwide has decreased since 2009, to nearly 1 billion, it is still unacceptably high. According to a recent FAO report, in Africa alone, nearly one-third of the population is undernourished and one child dies every six seconds because of the problem.

On October 16 of this year, countries, organizations, and communities are organizing events to educate and raise awareness, with the aim of addressing widespread problems in food supply and distribution systems. These events are raising money to support projects that focus on initiatives such as measures to ease population growth, boost incomes, and prepare farmers to protect their harvests against the negative effects of climate change, among others.

Throughout the world, organizations and governments are developing and implementing various plans to stabilize food prices and ensure that there is food on every table. Here are just a few examples:

   
• India. The government is in the process of enacting a food security act that would provide food for nearly 70 percent of the population, specifically targeting the poor, who are often not counted in state surveys and who are denied many benefits.

   
• Armenia. The government is enacting a sustainable development program that invests in infrastructure improvements, makes financial services and credit available to farmers, encourages the environmentally sustainable use of natural resources, and ensures food safety by improving food standards.

   
• Telefood. Launched in 1997 by the FAO, Telefood funds micro projects that help small-scale farmers at the grassroots level. The projects aim to help farmers be more productive and to improve both local communities' access to food and farmers' access to cash income. Telefood is involved in 130 countries worldwide.

   
• World Food Programme. The WFP operates in 74 countries and is the world's largest humanitarian agency fighting hunger. Currently, the Horn of Africa is suffering from the worst drought in 60 years, and 4 million people are in crisis in Somalia, with 750,000 people at risk of death in the next four months. WFP is providing food assistance to nearly 1 million people in Somalia and will scale up its operations during the coming months to reach some 1.9 million people.

   
• Hunger Free World. This Japanese NGO was formalized in 2000 with the goal of ending hunger and poverty through education and awareness around the world. The group supports local initiatives and young volunteers, organizes information programs, and joins forces with national and international networks to make these issues a priority for both citizens and politicians.

   
• Trussell Trust. This charity works to empower local communities to combat poverty and exclusion in the United Kingdom and Bulgaria. Last year, the group's U.K. food bank network fed more than 60,000 hungry people.

There is no single solution to end world hunger, and these are just a few of the organizations that are taking the multi-pronged approach that is necessary to address this global problem. World Food Day is the perfect occasion for researchers, policymakers, and NGOs to reflect on the existing efforts as well as potential future initiatives that can help fight global hunger and malnutrition.

Global meat production and consumption have increased rapidly in recent decades, with harmful effects on the environment and public health as well as on the economy, according to research done by Worldwatch Institute's Nourishing the Planet project for Vital Signs Online. Worldwide meat production has tripled over the last four decades and increased 20 percent in just the last 10 years. Meanwhile, industrial countries are consuming growing amounts of meat, nearly double the quantity in developing countries.

Large-scale meat production also has serious implications for the world's climate. Animal waste releases methane and nitrous oxide, greenhouse gases that are 25 and 300 times more potent than carbon dioxide, respectively.

Dirty, crowded conditions on factory farms can propagate sickness and disease among the animals, including swine influenza (H1N1), avian influenza (H5N1), foot-and-mouth disease, and mad-cow disease (bovine spongiform encephalopathy). These diseases not only translate into enormous economic losses each year--the United Kingdom alone spent 18 to 25 billion dollars in a three-year period to combat foot-and-mouth disease--but they also lead to human infections.

Mass quantities of antibiotics are used on livestock to reduce the impact of disease, contributing to antibiotic resistance in animals and humans alike. Worldwide, 80 percent of all antibiotics sold in 2009 were used on livestock and poultry, compared to only 20 percent used for human illnesses. Antibiotics that are present in animal waste leach into the environment and contaminate water and food crops, posing a serious threat to public health.

The amount of meat in people's diets has an impact on human health as well. Eaten in moderation, meat is a good source of protein and of important vitamins and nutrients such as iron, zinc, and vitamins B3, B6, and B12. But a diet high in red and processed meats can lead to a host of health problems, including obesity, diabetes, cardiovascular disease, and cancer.

Eating organic, pasture-raised livestock can alleviate chronic health problems and improve the environment. Grass-fed beef contains less fat and more nutrients than its factory-farmed counterpart and reduces the risk of disease and exposure to toxic chemicals. Well-managed pasture systems can improve carbon sequestration, reducing the impact of livestock on the planet. And the use of fewer energy-intensive inputs conserves soil, reduces pollution and erosion, and preserves biodiversity.

Further Highlights from the Research:

   
• Pork is the most widely consumed meat in the world, followed by poultry, beef, and mutton.

   
• Poultry production is the fastest growing meat sector, increasing 4.7 percent in 2010 to 98 million tons.

   
• Worldwide, per capita meat consumption increased from 41.3 kilograms in 2009 to 41.9 kilograms in 2010. People In the developing world eat 32 kilograms of meat a year on average, compared to 80 kilograms per person in the industrial world.

   
• Of the 880 million rural poor people living on less than $1 per day, 70 percent are partially or completely dependent on livestock for their livelihoods and food security.

   
• Demand for livestock products will nearly double in sub-Saharan Africa and South Asia, from 200 kilocalories per person per day in 2000 to some 400 kilocalories in 2050.

   
• Raising livestock accounts for roughly 23 percent of all global water use in agriculture, equivalent to 1.15 liters of water per person per day.

   
• Livestock account for an estimated 18 percent of human-caused greenhouse gas emissions, producing 40 percent of the world's methane and 65 percent of the world's nitrous oxide.

   
• Seventy-five percent of the antibiotics used on livestock are not absorbed by the animals and are excreted in waste, posing a serious risk to public health.

   
• An estimated 11 percent of deaths in men and 16 percent  of deaths in women could be prevented if people decreased their red meat consumption to the level of the group that ate the least.

   
• Eating organic, pasture-raised animals can be healthier and environmentally beneficial compared to industrial feedlot systems.

Policymakers around the world need to step up their efforts to combat hunger, malnutrition, and poverty by providing greater support for agriculture. The winners of this year's World Food Prize show how policymakers and leaders who invest in their countries' agricultural futures can make lasting change.

The World Food Prize, awarded each year since 1994 and sponsored by businessman and philanthropist John Ruan, recognizes the achievements of individuals who have advanced human development by improving the quality, quantity, or availability of food in the world, thereby helping to boost global food security. This year, the prize will be awarded to John Agyekum Kufuor, the former president of Ghana, and Luiz Inácio Lula da Silva, the former president of Brazil, for their outstanding achievements in reducing hunger in their countries. The ceremony will take place during the Borlaug International Symposium in Des Moines, Iowa, from October 12 to 14.

Both of this year's World Food Prize recipients have made considerable contributions to their countries' agricultural sectors. Under former Ghanaian President Kufuor's tenure, both the share of people suffering from hunger and the share of people living on less than $1 dollar a day were halved. Economic reforms strengthened public investment in food and agriculture, which was a major factor behind the quadrupling of the country's gross domestic product (GDP) between 2003 and 2008. Because 60 percent of Ghana's population depends directly on agriculture, the sector is critical for the country's economic development.
In addition to the economic reforms, Ghana's Agricultural Extension Service helped alleviate hunger and poverty by educating farmers and ultimately doubling cocoa production between 2002 and 2005. And the country's School Feeding Program, which began in 2005, ensures that school children receive one nutritiously and locally produced meal every day. The program has transformed domestic agriculture by supporting irrigation, improving seeds and crop diversification, making tractors more affordable for farmers, and building feed roads, silos, and cold stores for horticultural crops.

In Brazil, among the major goals of former President Luiz Inácio Lula da Silva's presidency were alleviating poverty, improving educational opportunities for children, providing greater inclusion of the poor in society, and ensuring that "every Brazilian has food to eat three times a day." The government implemented policies and actions known as the "Zero Hunger Programs" to provide cash aid to poor families (guaranteeing a minimum income and enabling access to basic goods and services); to distribute food to poor families through community restaurants, assisted-living facilities, day-care centers, and related organizations; and to provide nutritious meals to children in public schools. As a result, the number of hungry people in Brazil was halved, and the share of Brazilians living in extreme poverty decreased from 12 percent in 2003 to 4.8 percent in 2009.
Not just in Ghana and Brazil, but around the world, policymakers, farmers, activists, and other leaders are investing in agricultural innovations to reduce hunger and alleviate poverty--although many of these efforts need to be scaled up. In Uganda, for example, Project DISC (Developing Innovations in School Cultivation) is teaching students how to grow, cook, and eat native vegetables, including spiderwiki and amaranth. Not only are the students learning how to cook and provide for themselves, but the classes are giving them a reason to stay in rural areas and become farmers, instead of migrating to the cities. In other countries, including Niger, Kenya, Zambia, and Zimbabwe, farmers are learning how to increase their harvests and get more "crop per drop." In Benin, the Solar Electric Light Fund (SELF) has introduced solar-powered drip irrigation that is improving nutrition and raising incomes for farmers. After one year of implementing the innovation, villagers were eating three to five servings of vegetables a day, and children were going to school instead of spending time carrying water to the fields.

Unfortunately, agriculture is not often a top priority for policymakers--in Africa, only seven nations invest 10 percent or more of their national budgets in the sector. The leaders and policymakers--including former presidents Kufuor and da Silva--who have invested in agriculture and helped to reduce hunger and poverty in their countries deserve praise. But with some 1 billion hungry people remaining in the world who have to cope with volatile food prices, climate change, and water scarcity, much greater investment and policy support is needed to boost agriculture and improve global food security.

As summer comes to an end, school is just around the corner for children across the United States. For children enrolled in state schools, this typically means the return of unhealthy lunches that are best described as "fast food": hamburgers, chicken nuggets, fried snacks, and sugary soft drinks. Yet school lunch programs can play a key role in reinforcing healthy eating behaviors by integrating such measures as school gardens, nutrition education, locally sourced organic food, and efforts that affirm the value of mealtimes.

Childhood obesity is a major problem in North America, where annual obesity rates have seen significant gains in recent decades. According to the U.S. Centers for Disease Control and Prevention, 17 percent of U.S. children and adolescents aged 2-19 are obese, nearly triple the share in 1980. Many studies document the connection between a school's food environment and dietary behaviors in children. As anyone who grew up in the U.S. public school system can attest, lunches served in the country are highly processed and high in sodium, sugar, and fat.

Initiatives that connect schoolchildren to fresh, healthy foods and that encourage healthy eating habits from a young age are critical to ending the obesity endemic. One example is the U.S.-based 30 Project, which brings together key organizations and activists working on hunger, obesity, and agriculture to talk about their visions for the food system over the next 30 years. The effort is exploring long-term solutions to address obesity and improve the food system by ensuring that everyone has easy access to fresh fruits and vegetables, among other goals.

With children preparing to begin the school year, Nourishing the Planet offers the following five solutions for schools to encourage healthy eating:

• Connect Local Farmers to Schools: Providing locally sourced foods in school cafeterias improves diets and strengthens local economies. The U.S. state of Vermont is a leader in the nationwide Farm to School movement, which integrates food and nutrition education into classroom curricula and serves local foods in school cafeterias. Over the past decade, 60 percent of Vermont schools have joined the effort, forming a statewide network aided by the state's Agency of Agriculture, Department of Health, and Department of Education. Children benefit from farm-fresh foods for breakfast and lunch, and local farmers expand their business into a market worth over $40 million. Urban areas across the United States, from New York to Los Angeles, are also participating in this growing movement.


• Savor Mealtimes: Emphasizing the importance of mealtimes teaches children to appreciate the value and taste of good food. France, which has one of the lowest rates of childhood obesity in Europe, takes lunch very seriously. School lunches are well funded, and every part of the meal is prepared on school grounds in professional-grade kitchens--a stark contrast to the heat-and-serve kitchens in U.S. schools. Kids from preschool to high school are served four- to five-course meals and are encouraged to take time eating and socializing with friends. At some schools, detailed menus even suggest what parents should serve their children for dinner. Soft drink and snack machines are banned from school premises.


• Implement School Gardens: School gardens provide hands-on opportunities for children to cultivate and prepare organic produce. In the United States, REAL School Gardens creates learning gardens in elementary schools in high-poverty areas of north Texas. The organization has found that the school gardens not only nurture healthy lifestyles and environmental stewardship, but can also improve academic achievement through active participation. REAL School Gardens supports 81 schools, providing daily access to nature for more than 45,000 children and 2,700 educators.


• Nutrition Education: The city of Chicago's public school district doesn't offer mandatory nutrition education as part of its curriculum. To fill this void, the nonprofit Communities in Schools of Chicago (CISC) connects 170 schools to volunteer professionals who run a broad range of programs that address the social, emotional, health, and enrichment needs of students. Demand for nutrition classes has almost tripled in the past four years. This is due in part to the results of a Personal Health Inventory administered by CISC to more than 5,000 students, which showed that nutrition was the lowest scoring area.


• Equal Access to Healthy Foods: Childhood obesity disproportionately affects low-income families that may not be able to afford healthy foods. Schools in Greeley, Colorado, are taking a giant leap forward by cooking every meal from scratch. This is a much healthier alternative to the processed factory-food items that dominate school cafeterias today, and can be more cost effective for poorer school systems that take advantage of U.S. federal reimbursement rules. With 60 percent of the city's students qualifying for free or reduced-price meals, Greeley is proving that it isn't only rich school districts that can provide their children with healthy meals.

Additional Examples:

• The Community Alliance with Family Farmers (CAFF) coordinates relationships among school cafeterias and local food producers in California's San Francisco Bay Area, bringing nutritious meals to students who might not otherwise be able to afford them.


• The Fresh from the Farm program in Chicago conducts classroom activities such as tastings, cooking demonstrations, visits from farmers, helping in school gardens, and field trips to local organic farms.


• Revolution Foods delivers tasty and healthy breakfasts, lunches, and snacks to schools in Colorado, California, and Washington, D.C. Many of the ingredients are organic and locally sourced, and no artificial flavors, trans fats, high-fructose corn syrup, or milk with hormones and antibiotics are used at all.


• Seeds of Nutrition helps schools in Atlanta, Georgia, start school gardens and teach children how to prepare delicious recipes using the fruits of their labor. The group also collaborates with teachers to create cross-curricular lessons that center on gardens and food.


• The Edible Schoolyard in Berkeley, California, is a one-acre organic garden and kitchen classroom where inner-city students at a local Middle School participate in all aspects of growing, harvesting, and preparing seasonal produce.


• New York City's enormous school district used its market power to pressure vendors to reduce food prices and eliminate unhealthy items, including fried food, artificial ingredients, and trans fats, from its cafeterias. With this welcome change, many children now enjoy fresh fruit, salad bars, whole-grain breads and pasta, and foods made with low-fat and low-sodium recipes.


• In 2010, Italy adopted a nationwide policy to supply all school cafeterias with locally sourced organic food in an effort to curb childhood obesity and preserve culinary traditions. Seventy percent of all school cafeteria food in Rome is now organic, with ingredients coming from 400 Italian organic farms.

Obesity is an immense problem for children growing up in today's world of processed junk food, but many opportunities exist to reverse this trend. Schools are the most efficient means of transmitting healthy behavioral changes that can last a lifetime to students, families, and communities. It all starts with connecting schools to the best foods available: fresh, organic, and local.

China's environmental problems remain a cause for global concern as climate change continues to reduce agricultural production and create instability in world food prices, according to The Worldwatch Institute's report Green Economy and Green Jobs: Current Status and Potentials for 2020. The report was co-authored with a research team at the Institute for Urban and Environmental Studies led by Dr. Pan Jiahuathe. It cites alarming facts about the status of China's environmental stability, including the placement of seven Chinese cities on a list of the top ten most polluted places on earth. "In 2005, water in 59 percent of rivers was undrinkable, along with 70 percent of water reserves and inland lakes, and one quarter of all aquifers polluted with more than half of urban aquifers heavily polluted," according to the report.

In order to address its dire environmental problems, China is establishing millions of green jobs in the forestry, energy, and transportation sectors. In particular, China is making efforts to use wind and solar power to greatly reduce China's dependence on coal and create jobs in the manufacturing of wind turbines, solar photovoltaic panels, and solar water heaters. Additionally, the implementation of high-speed rail throughout the country will allow faster access to business centers and connect people from different regions, while creating jobs in manufacturing and service. While such efforts will help move China in a positive direction, the greatest opportunities for green jobs may be in the sustainable agriculture sector. Sustainable agriculture is a key component in reducing air pollution and water contamination, protecting forests and wildlife, all while producing nutritious food.

At a time when China's population is growing, producing healthy food is of critical importance.  But pollution has taken its toll on agriculture by reducing crop production, including a loss 10 million tons of grain production annually, according to the report. China is also facing its worst drought in 60 years which has caused food prices to go up, Oxfam USA notes that in March of this year food prices in China were nearly 12 percent higher than were the previous March. China has emphasized forestry as an effective way of addressing pollution while creating employment opportunities. The report states that forestation alone accounted for 1.8 million full-time green jobs in 2010, and that "nourishing these forested areas is vital for sustaining the country's green transition."

In addition, according to the report, agriculture is one of the largest users of energy in China and that China is also the world's largest producer of fertilizer. In 2010 China's fertilizer production totaled 66.20 million tons, the largest output in history.

China could also benefit from urban forests as a way to use agriculture to provide environmental benefits. When trees and other vegetation, like urban farms and gardens are planted they act like sinks for carbon dioxide in the atmosphere, thus contributing to reduction of greenhouse gases and reducing air pollution. Urban forests are being looked at by urban planners around the world, including China, as a way to contribute to the health of urban areas.

Worldwatch's report is the first to highlight China's move toward a green economy and the jobs created along the way. At a time when food security is of global concern and population growth continues to stress the environment, the innovations highlighted in the report have the potential to affect the world in a positive way. The report states "One of the greatest lessons to be learned from the early days of China's green transition is that building a sustainable future requires using approaches and processes that are sustainable in practice as well." With more China-focused projects in development, including a potential sustainable agriculture strategy for the northwestern regions, China could achieve both an effective and efficient transition towards green economy.

Women account for 75 percent of the agricultural producers in sub-Saharan Africa, but the majority of women farmers are living on only $1.25 per day, according to researchers from the Worldwatch Institute.

Despite the challenging circumstances that women in developing countries face, important innovations in communications and organizing are helping women play a key role in the fight against hunger and poverty. "Access to credit, which provides women farmers with productive inputs and improved technologies, can be an effective tool in improving livelihoods in Africa and beyond," said Worldwatch Institute's executive director Robert Engelman.

Worldwatch researchers traveled to 25 countries across sub-Saharan Africa to meet with more than 350 farmers groups, NGOs, government agencies, and scientists, highlighting innovations, such as better extension and communication services, that are helping farmers improve their livelihoods. The findings are documented in the recently released report, State of the World 2011: Innovations that Nourish the Planet.

Nourishing the Planet highlights four innovations that can strengthen women's agricultural capacity: providing microfinance credit, providing access to the global market, providing extension services, and providing organizational support to women's projects.

• Providing women with microfinance credit. Globally, women fall well short of receiving the same financial benefits and opportunities as men. Only 10 percent of the credit services available in sub-Saharan Africa, including small "microfinance" loans, are extended to women. The New York-based nonprofit Women's World Banking is the only microfinance network focused explicitly on women, providing loans of as little as $100 to help women start businesses. Microfinance institutions from 27 countries provide the loans to women who in many cases have no other way to access credit.

• Providing women access to the global market. In Africa's Western Sahel, the production of shea butter is boosting women's entry into global markets. Women-run cooperatives across the region are tapping into the global demand for fair trade and organic beauty products by selling the skin-care cream they produce from the shea nut crop to cosmetics firms such as Origins and L'Oréal. These "responsible" companies in turn pay fair price for the products and invest in the women's communities.

• Providing women with extension services. In the United States, outreach programs like Purdue Cooperative Extension Services offer training for women to grow their businesses and increase profitability. And in Uganda, agricultural extension workers have introduced women's groups to "coolbot" technology--solar energy and an inverter--that can be used in traditional reed, mud, and thatch shops to reduce temperatures and prolong the shelf lives of vegetables. "When extension programs invest in women farmers, the payoff can be huge," write Dianne Forte, Royce Gloria Androa, and Marie-Ange Binagwaho in State of the World 2011. "Women receive an education, raise yields, increase their incomes, and improve the nutritional status of family members, contributing to the wellbeing of entire communities."

• Helping women work together. Around the world, numerous organizations are helping to empower and support women farmers. In the United States, American Agri-Women, a coalition of farm, ranch, and agribusiness women's organizations, works with more than 50 state and commodity affiliates on legislative and regulatory matters as well as on student and consumer education. And the country's National Women in Agriculture Association helps socially disadvantaged women in rural areas obtain resources administered by the U.S. Department of Agriculture, with the mission to "educate, develop, network and create bonds of sisterhood among all women."

With a large percentage of women worldwide still lacking necessary services, it is time that policymakers include women, respect what they know, and stand beside them in pursuing the right to equality for all women. The ideas and technologies for the success of women are available, and development programs have the opportunity to thrive if they embrace the knowledge and skills of women farmers.

The trend of international land grabbing--when governments and private firms invest in or purchase large tracts of land in other countries for the purpose of agricultural production and export--can have serious environmental and social consequences, according to researchers at the Worldwatch Institute. Deals that focus solely on financial profit can leave rural populations more vulnerable and without land, employment opportunities, or food security.

The trend has accelerated as countries that lack sufficient fertile land to meet their own food needs--such as wealthier countries in the Middle East and Asia, particularly China--have turned to new fields in which to plant crops. "Growing demand and rising prices for food are leading some wealthier developing countries to seek secure access to food-producing land in the territory of lower-income ones," said Robert Engelman, Executive Director of Worldwatch. "If all governments capably represented the interests of their citizens, these cash-for-cropland deals might improve prosperity and food security for both sides. But that's not often the case. It's critical that international institutions monitor these arrangements and find ways to block those that are one-sided or benefit only the wealthy."

The International Food Policy Research Institute (IFPRI) reports that some 15-20 million hectares of farmland were the subject of deals or proposed deals involving foreigners between 2006 and mid-2009. Additional land acquisitions occurred in 2010, including deals in Ethiopia and Sudan, according to Andrew Rice, author of The Teeth May Smile but the Heart Does Not Forget and contributing author to the recent Worldwatch report State of the World 2011: Innovations that Nourish the Planet.

Critics of large-scale land acquisitions believe that the land grabs are marginalizing the land rights of local residents, particularly indigenous populations, and compromising food security in the host countries. "[Critics] predict that the outcome will not be development but a litany of dire possible consequences: xenophobia, riots, coups, and more hunger," writes Rice. Several organizations, including GRAIN, Oxfam, and the Oakland Institute, have reported on the negative consequences that such land deals have on developing countries.

Conversely, some experts argue that the agricultural development that occurs through land deals can provide poor countries with money, infrastructure, resources, and increases in food security. The International Institute for Economic Development, World Bank, U.N. Food and Agriculture Organization, and International Fund for Agricultural Development all have published documents highlighting the economic possibilities associated with international land deals.

Nourishing the Planet recommends three critical considerations to help guide global land transactions to promote mutual benefit:

   
• Well-defined land ownership. Research shows that when land      is legally titled, economic productivity improves. Figuring out who owns the land before acquisitions take place can help ensure the interests of smallholder farmers, promote local economic growth, and support community coordination with international investors. A country's history and lack of property rights can make land titling complicated. In Ethiopia's Gambella region, for example, much "unused" agricultural land is traveled by livestock herders, left to fallow, or used for hunting and gathering by indigenous people. These traditional land uses are easily dismissed without property rights.

   
• International cooperation and  consent. Development      experts agree that local residents should provide free, "prior and informed consent" to investors and government officials before land deals occur. But defining this consent and ensuring that deals operate within this rubric can be difficult. In the case of Mozambique, the government declared in 2007 that 30 million hectares of land was open for private investment. Although the government instituted consultations with local residents affected by potential deals, many local participants reported      coercion, asymmetric information, and multiple sales of single titles. As a result, the government was forced to halt the deals altogether.

   
• Complementing land deals with  domestic infrastructure development. Many land deals require additional investment in infrastructure to make the land suitable for efficient agricultural production. When coordinated with local residents, this      outside investment can lead to local employment and economic growth. At India's West Garo Hills Tea Factory, for example, a government agency paid for some processing machinery, a private company offered additional machinery, factory design, and training, and local communities provided land, bricks,      and labor. Not only does the partnership provide local jobs, but the processed tea from the factory is divided between the community and a private tea company.

We know that trees can help mitigate climate change by sequestering carbon dioxide from the earth's atmosphere. But what is less widely understood is how many of these trees can also help to bring an end to hunger and poverty.

Today, Nourishing the Planet takes a look at five varieties of tree that you have likely never heard of, but that are helping to alleviate hunger and poverty and protect the environment.

1.     Black Plum: Black plums are common across tropical sub-Saharan Africa's coastal savannas and savanna woodlands. The black plum tree is not domesticated, but it is widely utilized and protected, and is often found at the center of West African villages. The black plum is useful in agroforestry and organic farming. It is nitrogen fixing, meaning it adds nitrogen to the soils it grows in. Whether the tree is growing in fields or along boundaries, crops can benefit from natural soil nutrients. Leaves from the tree are also used as nutrient-rich mulch.

Best Way to Eat It: The fruit makes good quality jellies and jams, as well as a black molasses. A beverage similar in flavor to coffee is also made from roasted fruits. Young, leafy shoots from the tree are picked, boiled, seasoned, and eaten like spinach.

Black Plum in Action: Black plum trees' fruit and leaves support wildlife and its nitrogen fixing abilities encourage soil health. Its deep roots protect soils from erosion, benefitting other plant life and helping rebuild degraded ecosystems.

2.     Ebony: Ebony wood is world renowned for its dense fine-grain quality and rich dark color. It is prized for use in musical instruments, such as pianos and violins, and is considered superior for woodcarving. The tropical species--including Africa's most common, the jackalberry (Diospyros mespiliformis)--produce the finest ebony wood and a fruit akin to the persimmon.

Best Way to Eat It: The fruits are commonly eaten fresh, dried, or pulped for sauces. They can be used in porridges and toffee, brewed into beer, fermented into wine, and distilled into an ebony brandy. In Namibia they are made into a hot liqueur called ombike.

Ebony in Action: The roots of the jackalberry tree are made into a mixture for treating dysentery and fever and getting rid of parasites. The mixture has also been used to help treat leprosy in Southern Africa. Ebonies are also protecting African communities from famine. The tree's deep roots keep its leaves green during drought, which can be emergency fodder for grazing livestock when grasses dry up.

3.     Marula: The marula tree is found throughout 29 sub-Saharan African countries--from Cape Verde to Ethiopia to South Africa. While the tree is not domesticated, the marula tree has been intentionally cultivated in the wild for hundreds of years, and its distribution closely matches human migration patterns.

Best Way to Eat It: In the center of each fruit is a large nut stone, which contains a soft macadamia-like nut kernel. The highly nutritious kernels, which are eaten raw and roasted, are rich in antioxidants.

Marula in Action: In South Africa alone, around 500 tons of marula fruit is commercially processed for juice and 2,000 tons for Amarula Cream every year. In Namibia, Botswana, Zimbabwe, and South Africa, fruits are often collected and sold by villagers to marula processing facilities.

4.     Dika: Indigenous to West Africa, a Dika tree can grow to be as tall as 40 meters and produces a small green and yellow fruit that looks, at first glance, like a small mango. When forests are cleared in West Africa for firewood or for farmland, the Dika trees are, more often than not, left untouched. Farmers have too much to gain from harvesting the tree's fruits and seeds.

Best Way to Eat It: Resembling smooth walnuts, Dika seeds are cracked open by harvesters to collect the edible kernel contained inside. These kernals can be eaten raw or roasted, but most are processed and pounded into Dika butter or compacted into bars or pressed to produce cooking oil.

Dika in Action: Each year, thousands of tons of "Dika nuts" are harvested throughout Western Africa, providing a critical income to millions of farmers and harvesters throughout West Africa.

5.     Moringa: Serving not only as a reliable source of food, moringa also provides lamp oil, wood, paper, liquid fuel, skin treatments, and the means to help purify water. The moringa tree comprises 4 different edible parts: pods, leaves, seeds, and roots.  The green-bean looking pods are the most sought-after parts, not only because of their taste - similar to asparagus - but also because they are highly nutritious. Moringa trees are also used in agroforestry and mixed cropping because the shade can protect other crops from the sun and, while smoke from household fires can pollute the air, the soft, spongy moringa wood burns cleanly with little smoke or odor, making it a cleaner source of fuel.

Best Way to Eat It: People commonly boil the tiny leaflets and eat them like spinach.  Like the pods, the leaves contain vitamins A and C as well as more calcium than most other greens. These leaves also contain such high levels of iron that doctors frequently prescribe them for anemic patients.

Moringa in Action: The moringa tree is best known for its endless supply of food, but one of the most innovative uses of the plant has been to treat water and wastewater.  Researchers at Leicester University in the United Kingdom, have found that mixing crushed moringa seeds with polluted water help settle silt and other contaminants. This is highly cost effective because the seeds can replace the expensive imported material usually used for water purification in rural areas. The seed filtered water still needs a final filtration before it is completely drinkable, but the seeds make the process easier and help other water filters last longer.

Agricultural production is only the first step in moving the world's food from farm to fork, according to Nourishing the Planet, a project of the Worldwatch Institute. The other links in the food chain--harvesting, packaging, storing, transporting, marketing, and selling--ensure that food actually reaches consumers. Inefficiencies in these activities, rather than just low yields or poor farming techniques, are often to blame for food shortages and low prices for growers.

With the United Nations projecting a global population of more than 9 billion by 2050, increasing food chain efficiency will become ever more essential. Producers and consumers must be part of a food chain that feeds the world, provides fair prices to farmers, and works in harmony with the environment. "When groups of small farmers better organize their means of production--whether ordering the right inputs at the right time or selling their crops directly to customers--they become more resilient to fluctuations in global food prices while also better serving local communities," said Robert Engelman, Executive Director of Worldwatch.

In State of the World 2011, contributing author Samuel Fromartz uses the example of corn production in Zambia to illustrate how off-farm inefficiencies exacerbate food insecurity and poverty. Poor market access, unpredictable weather patterns, and insufficient infrastructure make small-scale agriculture a high-risk livelihood. Seasons of surplus corn production can be as detrimental as low-yielding ones. Large surpluses saturate local markets, and local farmers have no alternatives for selling their product. "Many do not have the luxury of picking when to sell or whom to sell to; they are desperate and need to sell to eat. So they take whatever price they can get," writes Fromartz.

Research done by Nourishing the Planet staff has found innovations in sub-Saharan Africa and other locations around the globe that improve market access, enhance farmer-to-farmer communication, and harness simple information technology. These improvements in the food chain provide farmers with fair prices and also help increase food security by distributing food efficiently.

Nourishing the Planet recommends three ways that agriculture is helping to address gaps in the current food supply chain:

• Coordinating farmers. In Uganda, the organization Technoserve works with farmers to improve market conditions for sales of bananas. Technoserve helps individuals form business groups that receive technical advice and enter into sales collectively. Coordinating business has decreased transaction costs and helped farmers market their crops and compete with larger producers more effectively. Over 20,000 farmers now participate in the project. Farmers in the United States are also banding together to increase sales efficiency and fair prices. The Chesapeake Bay regions's FRESHFARM Markets act as an organizational umbrella under which area farmers can coordinate, market, and sell their products.

• Increasing market transparency. In Nairobi, Kenya, the DrumNet project uses simple communication technology to provide farmers with real-time market information. Having access to market prices and sale-coordination opportunities allows farmers to receive fair prices for their crops. And the transparency increases overall sales transactions, meaning that less food goes to waste.

• Using low-cost technology to boost efficiency. According to the UN, over 5 billion people on the planet now have a mobile phone subscription. As the cost of the technology drops, using the devices beyond personal communication makes sense. In Niger, farmers use mobile  phones to access market information, an application that has reduced the fluctuation in regional grain prices by 20 percent and has helped ensure fair prices for producers and consumers. Similarly, the Grameen Foundation and Google have collaborated to develop Google Trader, an online bulletin board on which farmers and merchants can contact one another. The bulletin also includes applications such as "Farmer's Friend" a tool that offers farmers information on weather, pests, and livestock management.

As the global population increases, so does the number of mouths to feed. The good news is that in addition to providing food, innovations in sustainable agriculture can provide a solution to many of the challenges that a growing population presents. Agriculture is emerging as a solution to mitigating climate change, reducing public health problems and costs, making cities more livable, and creating jobs in a stagnant global economy.

According to staggering new statistics from the United Nations Food and Agriculture Organization (FAO), roughly one-third of the food produced worldwide for human consumption is lost or wasted, amounting to some 1.3 billion tons per year. In the developing world, over 40 percent of food losses occur after harvest--while being stored or transported, and during processing and packing. In industrialized countries, more than 40 percent of losses occur as a result of retailers and consumers discarding unwanted but often perfectly edible food.

As people move from rural to urban settings in search of economic opportunities, urban agriculture is becoming an important provider of both food and employment, according to researchers with the Worldwatch Institute. "Urban agriculture is providing food, jobs, and hope in Nairobi, Kampala, Dakar, and other cities across sub-Saharan Africa," said Danielle Nierenberg, co-director of the Institute's Nourishing the Planet project. "In some cases, urban farmers are providing important inputs, such as seed, to rural farmers, dispelling the myth that urban agriculture helps feed the poor and hungry only in cities."

Global fish production has reached an all-time high, according to Nourishing the Planet's latest research for the Worldwatch Institute's Vital Signs Online publication. Aquaculture, or fish farming--once a minor contributor to total fish harvest--increased 50-fold between the 1950s and 2008 and now contributes nearly half of all fish produced worldwide.

According to the U.N. Food and Agriculture Organization an estimated 53 percent of fisheries are considered fully exploited--harvested to their maximum sustainable levels--with no room for expansion in production. Population growth and a higher demand for dietary protein are putting increasing pressure on depleted stocks and threatened ecosystems.

Increased farming of large predators, such as salmon and tuna, has led to overfishing of prey fish--including anchoveta and herring, which are commonly used as fishmeal. It generally takes at least three kilograms of feed to produce one kilogram of salmon. The shrinking of the numbers of prey species threatens the entire food chain, putting further stress on large predator stocks.

Depleting fisheries also negatively affect the economies of developing countries, home to the nearly 60 percent of the world's fishers that are classified as small-scale commercial or subsistence fishers. In Africa, an estimated 100 million people depend on fish from inland sources, such as lakes and rivers, for income as well as protein and much-needed micronutrients like vitamin A, calcium, iron, and zinc. But coastal fisheries across West Africa have declined by up to 50 percent in the last 30 years due to significant pressure from large industrial fleets.

Fisheries also provide important ecosystem services, such as storing and recycling nutrients and absorbing pollutants. We need to make ecological restoration as much a goal as meeting the growing global demand for seafood. And we must move away from mainstream approaches that focus narrowly on short-term profit and boosting production to more sustainable strategies that help meet demand and support fishing communities.

Around the world, fisheries co-managed by local authorities and fishers themselves are emerging as a promising solution to replenishing depleting fish stocks.

In 2007, a group of Gambian women oyster harvesters formed the TRY Women's Oyster Harvesting Association. They collectively agreed to close one tributary in their oyster territories for an entire year and to shorten their harvest season by two months. These practices may seem difficult in the short run, but they pay off over time, securing incomes and nutrition in their communities.

Focusing on fisheries can help boost incomes and strengthen food security, while protecting the ecosystems on which millions of people worldwide depend.

Increasing demand for water continues to put a strain on available water sources, threatening the livelihood of millions of small-scale farmers who depend on water for their crops. At a time when one in eight people lack access to safe water, Nourishing the Planet points to low-cost, small-scale innovations to better manage this vital resource. These efforts are increasing the availability of water for crops and helping farmers improve crop productivity and become more food-secure.

Seventy percent of the world's freshwater is used for irrigation, and global water resources are drying up as climate change takes hold and population growth continues. 60 percent of the world's hungry people live in South Asia and sub-Saharan Africa--most of them on small farms--where they do not have a reliable source of water to produce sufficient yields. Only 4 percent of the cultivated land in sub-Saharan Africa is currently equipped for irrigation. 95 percent of cropland in the region depends on rain, and climate scientists predict that rainfall on the continent will decline in the coming decades. But there is great potential to expand irrigation with small-scale solutions.

The Green Revolution of the 1960s led to a near tripling of global grain production and a doubling of the world's irrigated area. It also, however, demanded vast quantities of water. Previous agricultural investments have focused narrowly on increasing crop yields, while there has been relatively little research and investment in ways to make better use of scarce water resources. Affordable innovations that boost agricultural development and meet the increasing demand on already-scarce water resources while also mitigating the impacts of climate change, are more important than ever.

Nourishing the Planet recommends three models for effective water management that have the potential for getting `more crop per drop':

Human-powered pumps. The foot-operated treadle pump enables 2.3 million farmers in the developing world--some 250,000 in sub-Saharan Africa--to boost crop productivity, improve harvest reliability, and raise incomes. The original $35 version can irrigate 0.2 hectares with ground water; newer models can irrigate up to 0.8 hectares and cost no more than $140 installed. These devices already generate $37 million a year in profits and wages. In Zambia, International Development Enterprises worked with farmers to determine the most effective type of pump. The Mosi-O-Tunya pump is manufactured locally and delivers 25 percent more water per second than older versions.

Affordable micro-irrigation. A suite of low-cost drip irrigation technologies is helping farmers use limited water supplies more efficiently, often doubling water productivity. These systems deliver water directly to the plant roots through perforated pipes or tubes, and can come in the form of $5 bucket kits, $25 drum kits, or $100 shiftable drip systems that irrigate up to 0.2 hectares. Solar-powered micro-irrigation drip systems are also making their debut in West Africa. One study found that after a year of using these systems, villagers in Benin had higher incomes and protein in their diets. Children attended school more often, since they no longer needed to spend their day collecting water.

More effective use of rainfall. Conservation tillage methods that leave the soil intact; timely weeding and mulching; and planting vegetative barriers all help to maximize green water, or rainwater stored in the soil and plants as moisture. Rainwater harvesting using small earthen dams and other methods also helps maximize rainwater utility. Supplementing these practices with irrigation may produce optimal results. In Kenya, Maasai women are working with the U.N. Environment Programme and the World Agroforestry Centre to build rooftop catchment tanks, which provide water for their households and save women time collecting water.

Satisfying the water requirements of the future, while also coping with population growth, increasing consumption, persistent poverty, and a changing climate, will take a commitment well beyond what has materialized to date. Support--and research and investment--from governments, development agencies, and international and national NGOs can help make such technologies more accessible to smallholder farmers.

For over 40 years, Earth Day has served as a call to action, mobilizing individuals and organizations around the world to address these challenges. This year Nourishing the Planet highlights agriculture--often blamed as a driver of environmental problems--as an emerging solution.

Agriculture is a source of food and income for the world's poor and a primary engine for economic growth. It also offers untapped potential for mitigating climate change and protecting biodiversity, and for lifting millions of people out of poverty.

This Earth Day, Nourishing the Planet offers 15 solutions to guide farmers, scientists, politicians, agribusinesses and aid agencies as they commit to promoting a healthier environment and a more food-secure future.

1. Guaranteeing the Right to Food. Guaranteeing the human right to adequate food--now and for future generations--requires that policymakers incorporate this right into food security laws and programs at the regional, national, and international level. Governments have a role in providing the public goods to support sustainable agriculture, including extension services, farmer-to-farmer transmission of knowledge, storage facilities, and infrastructure that links farmers to consumers.

2. Harnessing the Nutritional and Economic Potential of Vegetables. Micronutrient deficiencies, including lack of vitamin A, iodine, and iron, affect 1 billion people worldwide. Promoting indigenous vegetables that are rich in micronutrients could help reduce malnutrition. Locally adapted vegetable varieties are hardier and more dependable than staple crops, making them ideal for smallholder farmers. Research organizations like AVRDC/The World Vegetable Center are developing improved vegetable varieties, such as amaranth and African eggplant, and cultivating an appreciation for traditional foods among consumers.

3. Reducing Food Waste. Experts continue to emphasize increasing global food production, yet our money could be better spent on reducing food waste and post-harvest losses. Already, a number of low-input and regionally appropriate storage and preservation techniques are working to combat food waste around the world. In Pakistan, farmers cut their harvest losses by 70 percent by switching from jute bags and containers constructed with mud to more durable metal containers. And in West Africa, farmers have saved around 100,000 mangos by using solar dryers to dry the fruit after harvest.

4. Feeding Cities. The U.N. estimates that 70 percent of the world's people will live in cities by 2050, putting stress on available food. Urban agriculture projects are helping to improve food security, raise incomes, empower women, and improve urban environments. In sub-Saharan Africa, the Educational Concerns for Hunger Organization (ECHO) has helped city farmers build food gardens, using old tires to create crop beds. And community supported agriculture (CSA) programs in Cape Town, South Africa, are helping to raise incomes and provide produce for school meals.

5. Getting More Crop per Drop. Many small farmers lack access to a reliable source of water, and water supplies are drying up as extraction exceeds sustainable levels. Only 4 percent of sub-Saharan Africa's cultivated land is equipped for irrigation, and a majority of households depend on rainfall to water their crops--which climate scientists predict will decline in coming decades. Efficient water management in agriculture can boost crop productivity for these farmers. By practicing conservation tillage, weeding regularly, and constructing vegetative barriers and earthen dams, farmers can harness rainfall more effectively.

6. Using Farmers' Knowledge in Research and Development. Agricultural research and development processes typically exclude smallholder farmers and their wealth of knowledge, leading to less-efficient agricultural technologies that go unused. Research efforts that involve smallholder farmers alongside agricultural scientists can help meet specific local needs, strengthen farmers' leadership abilities, and improve how research and education systems operate. In southern Ethiopia's Amaro district, a community-led body carried out an evaluation of key problems and promising solutions using democratic decision-making to determine what type of research should be funded.

7. Improving Soil Fertility. Africa's declining soil fertility may lead to an imminent famine; already, it is causing harvest productivity to decline 15-25 percent, and farmers expect harvests to drop by half in the next five years. Green manure/cover crops, including living trees, bushes, and vines, help restore soil quality and are an inexpensive and feasible solution to this problem. In the drought-prone Sahel region, the Dogon people of Mali are using an innovative, three-tiered system and are now harvesting three times the yield achieved in other parts of the Sahel.

8. Safeguarding Local Food Biodiversity. Over the past few decades, traditional African agriculture based on local diversity has given way to monoculture crops destined for export. Less-healthy imports are replacing traditional, nutritionally rich foods, devastating local economies and diets. Awareness-raising initiatives and efforts to improve the quality of production and marketing are adding value to and encouraging diversification and consumption of local products. In Ethiopia's Wukro and Wenchi villages, honey producers are training with Italian and Ethiopian beekeepers to process and sell their honey more efficiently, promote appreciation for local food, and compete with imported products.

9. Coping with Climate Change and Building Resilience. Global climate change, including higher temperatures and increased periods of drought, will negatively impact agriculture by reducing soil fertility and decreasing crop yields. Although agriculture is a major contributor to climate change, accounting for about one-third of global emissions, agricultural practices, such as agroforestry and the re-generation of natural resources, can help mitigate climate change. In Niger, farmers have planted nearly 5 million hectares of trees that conserve water, prevent soil erosion, and sequester carbon, making their farms more productive and drought-resistant without damaging the environment.

10. Harnessing the Knowledge and Skills of Women Farmers. According to the U.N. Food and Agriculture Organization, women represent 43 percent of the agricultural labor force, but due to limited access to inputs, land, and services, they produce less per unit of land than their male counterparts. Improving women's access to agricultural extension services, credit programs, and information technology can help empower women, while reducing global hunger and poverty. In Uganda, extension programs are introducing women farmers to coolbot technology, which uses solar energy and an inverter to reduce temperatures and prolong the shelf life of vegetables.

11. Investing in Africa's Land: Crisis and Opportunity. As pressure to increase food production rises, wealthy countries in the Middle East and Asia are acquiring cheap land in Africa to increase their food productivity. This has led to the exploitation of small-scale African farmers, compromising their food security. Agricultural investment models that create collaborations between African farmers and the foreign investing countries can be part of the solution. In Ethiopia's Rift Valley, farmers grow green beans for the Dutch market during the European winter months, but cultivate corn and other crops for local consumption during the remaining months.

12. Charting a New Path to Eliminating Hunger. Nearly 1 billion people around the world are hungry, 239 million of whom live in sub-Saharan Africa. To alleviate hunger, we must shift our attention beyond the handful of crops that have absorbed most of agriculture's attention and focus on ways to improve farmers' access to inputs and make better use of the food already produced. Innovations--such as the human-powered pump that can increase access to irrigation and low-cost plastic bags that help preserve grains--offer models that can be scaled-up and replicated beyond Africa.

13. Moving Ecoagriculture into the Mainstream. Agricultural practices that emphasize increased production have contributed to the degradation of land, soil, and local ecosystems, and ultimately hurt the livelihoods of the farmers who depend on these natural resources. Agroecological methods, including organic farming practices, can help farmers protect natural resources and provide a sustainable alternative to costly industrial inputs. These include rotational grazing for livestock in Zimbabwe's savanna region and tea plantations in Kenya, where farmers use intercropping to improve soil quality and boost yields.

14. Improving Food Production from Livestock. In the coming decades, small livestock farmers in the developing world will face unprecedented challenges: demand for animal-source foods, such as milk and meat, is increasing, while animal diseases in tropical countries will continue to rise, hindering trade and putting people at risk. Innovations in livestock feed, disease control, and climate change adaptation--as well as improved yields and efficiency--are improving farmers' incomes and making animal-source food production more sustainable. In India, farmers are improving the quality of their feed by using grass, sorghum, stover, and brans to produce more milk from fewer animals.

15. Going Beyond Production. Although scarcity and famine dominate the discussion of food security in sub-Saharan Africa, many countries are unequipped to deal with the crop surpluses that lead to low commodity prices and food waste. Helping farmers better organize their means of production--from ordering inputs to selling their crops to a customer--can help them become more resilient to fluctuations in global food prices and better serve local communities that need food. In Uganda, the organization TechnoServe has helped to improve market conditions for banana farmers by forming business groups through which they can buy inputs, receive technical advice, and sell their crops collectively.
