This timeline tracks forty years of experimentation, experience and debate on farmer-centred, participatory agricultural research, innovation and extension. The timeline concentrates particularly on events associated with a series of landmark workshops that took place at the Institute of Development Studies, Sussex, UK, over a twenty-year period: "Farmer First" in 1987, "Beyond Farmer First" in 1992 and a third workshop, "Farmer First Revisited", which took place on 12-14 December 2007.That workshop reflected on 20 years of experience in the field and assessed opportunities and challenges for the future. Both participants and non-participants in the Farmer First Revisited conference are warmly invited to contribute to this timeline. In order to do so, you need to (a) create a persona...more >>l account and (b) join the Farmer First Revisited group.You can locate the group by clicking on the Groups tab at the top of any web-page and then using the alphabetical search facility to find the FFR group.
