This chapter discusses the conservation of crop resources, with a focus on in situ, or on-farm, conservation. A number of different strategies are proposed to promote in situ conservation. One strategy is to increase the supply of traditional crop material to farmers who rely on seed exchange but face increasing difficulties in obtaining landraces. A second and more elaborate strategy is to increase the value of local crops so that farmers will maintain these rather than switch entirely to improve the varieties. The chapter reveals that participatory plant breeding has been identified as a method to achieve two goals which are often assumed to be contradictory: improving crop production and maintaining genetic diversity. It also discusses how although participatory crop improvement has been shown to be successful in meeting production goals, it has never been evaluated for achieving conservation goals.
