The challenges we face towards achieving food and nutritional security are substantial, if not daunting. We are putting our whole agricultural system at risk through a series of converging factors that have become global in nature (climate change, increased soil degradation and water stress, decrease in soil fertility, industrial and agricultural pollution, rapid demographic growth we can ill afford and commodity speculation forcing food prices upwards).
One cannot get away from the triangle: population-C02-natural resources. Right now the combination population-technology is widening the gap between humanty's footprint and the available biocapacity. The biotehcnological solutions proposed to date are also either inadequate, problematic or still experimental and so not capable of redressing the situation within the temporal limits we now have to work in, in which we are confronted with having to try and feed an 2 extra billion or more by 2050! Therefore unless we bring our population levels down and restore soil fertility we are unlikely to succeed. This means promoting agro-ecological alternatives over agricultural intensification.
It is in these two areas that we need to focus all our efforts, as well as on making sure temperatures to do not rise above 2 C. I attach a paper on why another Green Revolution in Africa (or elsewhere for that matter) is unadvisable, as the points are relevant to both themes I and II. Respectfully submitted by Dr. A. Marcar.
