Effective agricultural improvement work grows out of years and years of trying one approach after another, of searching constantly for new, more effective ways of working.  Each new approach must not only be tried out, but must be evaluated on the basis of generous amounts of feedback from the field.  This feedback deals with the approach’s psychological and social as well as agricultural impact.  This process is always an expensive and time-consuming job, but it is absolutely essential if those of us working in development are ever to meet the challenge of agricultural improvement.
