Then abstract the various Topics: GM, water depletion, transference of food crops to bio-fuel production, rural economic diversity, overpopulation, Climate Change, & etc with their associated diaries/comments -- something like I did here. (which I then let lapse, my bad.)
Then construct a flow-chart or Fuzzy-Cognitive Map or some other Modeling tool to provide a Top-Down and Bottom-Up Index.
Goal: provide a quality Information Source for position papers and decision-makers.
Next, I think a debate might be the occasion for identifying the issues & topics, as well as sketching the outlines of solutions (debatable of course).
Then attempt the type of tool you suggest, for which we don't have a slot. The ETwiki was supposed to do this kind of thing, but it's spam-botted to hell.
The fuzzy-cognition tool I may leave to others... ;)
As to the second, I know how to do that. The challenge will be getting enough time to do it. But that's OK. My feeling is it's better to start with high-quality but limited rather than lots and lots of nuthin.
