Organic EprintsWhat can organic agriculture contribute to sustainable development? – Long-term comparisons of farming systems in the tropicsCh.ZundelauthorL.KilcherauthorP.MäderauthorDespite the high demand for sound data on the agronomic, ecological and economic performance of organic agriculture in developing countries, systematic comparison of organic and conventional farming systems has not so far been carried out. The Research Institute of Organic Farming (FiBL), together with its partners, is presently establishing long-term comparisons of farming systems in various agro-ecological and agro-economic contexts to study the different parameters that are essential for sustainable development. To date, three study areas have been selected: (a) a sub-humid area in Kenya where farming is subsistence-oriented; (b) a semi-arid area in India where cotton is produced for the export market; and (c) a humid area in Bolivia where perennial fruits and cacao are produced for the domestic and export markets. The key elements in these comparisons are replicated long-term field trials. These are complemented by farm surveys and short-term trials under on-farm conditions. This network of comparison of farming systems in the tropics is expected to (1) put the discussion on the benefits and drawbacks of organic agriculture on a rational footing; (2) help to identify challenges for organic agriculture that can then be addressed systematically; (3) provide physical reference points for stakeholders in agricultural research and development and thus support agricultural policy dialogue at different levels.
