Timed to coincide with the UN climate convention negotiations in South Africa, this study by UNEP argues that the world has the technological and economic solutions to avert climate change.

A study published in September 2008 finds that organic agriculture in Africa can be equal or better for food security than most conventional systems and is more likely to be sustainable in the longer term, as it builds up levels of natural, human, social, financial and physical capital in farming communities. It also favours the use of low carbon footprint production methods and local resources.

This paper argues that organic agriculture can feed the world. The authors state that the principal objections to the proposition that organic agriculture can contribute significantly to the global food supply are low yields and insufficient quantities of organically acceptable fertilizers. They evaluate the universality of both claims.
