Agriculture is an urgent priority worldwide and farmers in the developing world find themselves in the front line of some of the world’s most pressing issues – climate change, globalization and food security. The problem with the agricultural research and extension which is meant to support these farmers is that it is often delivered in a linear, top-down fashion which is inappropriate to their social, physical and economic needs. Twenty years ago, the Farmer First workshop at the Institute of Development Studies, University of Sussex, UK, started from this premise, and launched amovement to encourage farmer participation in agricultural research andextension so as to find better solutions to farmers’ needs.Since that time methodological, institutional and policy experiments have unfolded around the world – all aimed at putting farmers first. Farmer First Revisited presents accounts of such experiments which were brought by delegates to a workshop in December 2007 and which include successes and failures and the lessons that have been learned.
