“In Mexico, farmers who noticed velvetbean growing wild in their fields used it to increase soil fertility and improve maize yields. In Northern Ethiopia, farmers reclaimed farmland from a river by constructing walls in the river bed and diverting the water flow. In India, an innovative farmer designed a tree plantation that successfully survived a severe three-year drought. Farmers' innovations have stood the test of time and hold the potential to meet the challenges of increasing production and managing the natural resource base.
During the last 40 or 50 years, however, many farmers have relied less on their own experimentation and innovation, and become more dependent on outside information provided through extension systems. This has had the effect of disempowering many farmers, as they became passive recipients of knowledge and technology.”
