The report examines two possible scenarios. The first emphasizes economic growth over environmental concerns and necessitates an 80% increase in agricultural production. The second takes global ecology into account, and requires only a 30% increase in agricultural production while necessitating a cutback in overall food consumption in developed countries. Subsequent reports will look more closely at other issues, such as changing standards of living, climate change, and land usage.
A report that finds there are viable ways to end world hunger is good news indeed. Also, the organizations report that Africa’s agricultural productivity doubled between 1961 and 2003. However, agricultural productivity ether doubled or tripled in other continents as well. Thus, agricultural productivity in Africa is still the lowest in the world. BUT… Many looming questions remain as to how best to address food shortages in a way that is sustainable over the long term.
