Organic agriculture reduces the risk of yield failure, stabilizes returns and improves the quality of life of small farmers’ families. To date, no systematic attempt has been made to evaluate the benefits and effects of each system. In 2006, FiBL therefore launched a network of long-term system comparisons in the tropics that aims at examining the contribution of organic agriculture to food security, poverty alleviation and environmental conservation. The article presents this discussion based on experience gained in practice and encompasses the following hypotheses: 1.
