Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

Container gardening on a windowsill

by willem vancotthem Thu Jun 12th, 2008 at 09:38:40 AM EST

Mrs. Heidi HOUGH from Chicago has sent me the following message : "I've got some cool-weather greens growing in plastic boxes (with drainage holes) up on our second-story window sills. Arugula, spinach, chard, French breakfast radish, and lettuces. I like to eat them right out of the box (like a grazing animal--I am shameless)". I also received Heidi's magnificent pictures of her "windowsill garden". I believe that just a look at them will convince a lot of people to follow this splendid example, showing how simple and easy it is to produce fresh food in and around the house, even on a windowsill in a city like Chicago.  Therefore, I posted her message and pictures on my blog : http://containergardening.wordpress.com/

Family gardens, school gardens and urban gardening against the actual food crisis

by willem vancotthem Thu Jun 5th, 2008 at 05:45:19 PM EST

Drought is described as a very important environmental constraint, limiting plant growth and food production. The World Food Program (WFP) has recently indicated drought in Australia as one of the major factors for the difficulty to deliver food aid to millions of people suffering from hunger and malnutrition. Drought is seen as the force driving up wheat and rice prices, which contributes directly to food shortage, social unrest and disturbances at the global level. Therefore, mitigating drought and limiting water consumption seems to be essential factors for resolving the actual food crisis and to find long-term solutions to malnutrition, hunger and famine, particularly in the drylands.

Application of water stocking soil conditioners, keeping the soil moistened with a minimum of irrigation water, and seeding or planting more drought tolerant species and varieties will definitely contribute to solve the food crisis. Scientists in China and the USA have recently discovered important genetic information about drought tolerance of plants. It was thereby shown that drought tolerant mutants of Arabidopsis thaliana have a more extensive root system than the wild types, with deeper roots and more lateral roots, and show a reduced leaf stomatal density. My own research work on the soil conditioning compound TerraCottem has led to similar conclusions : treatment with this soil conditioner induced enhancement of the root system with a higher number of lateral roots. More roots means more root tips and thus a higher number of water absorbing root hairs, sitting close to the root meristem. As a result, plants with more roots can better explore the soil and find the smallest water quantities in a relatively dry soil.

As the world's population is growing by about 78 million people a year, it affects life on this earth in a very dramatic way. Droughts have caused a rise of food prices many times before, but the present situation is quite different, because it is based on specific trends and facts : the faster growing world population and a definite change in international food consumption trends and habits.
