註釋The international debate on biodiversity has resulted in a renewed interest in the role of farmers and local communities in the management of natural resources and crop genetic diversity. The local varieties of crops which have been developed by farmers have made a great contribution to plant breeding genetic resources in the North. In recent years it has become apparent that local crop diversity in the South is threatened by promotion of modern varieties promising higher yields. This study reflects new approaches and concepts in the field of conservation and the development of local crops.
