What is the contribution of organic agriculture to sustainable development? Results from the Long-term Farming Systems Comparisons Trials

Summary

The farming systems comparisons trials in Kenya have been running since 2007 at two trial sites (Chuka and Thika). The trials compare the economic, ecological, and sustainable performance of organic and conventional farming systems at a high and low input level. Results showed comparable productivity in conventional and organic systems for cereals but lower yields in organic for potatoes and leafy vegetables. Production costs are generally higher in organic due to the higher labor costs. However, soil fertility and biodiversity are better in organic systems. To fully exploit the potential of organic systems, further innovations in organic pest and input management have to be developed, and capacity building has to be strengthened.
