ABSTRACT
In this chapter, the authors argue that in-situ conservation of native crop diversity is achievable only through preservation of agroecosystems under traditional management, and furthermore, only if the management is guided by the local knowledge of the plants and their requirements. Home gardens also provide diverse environments where many wild species of animals and plants can live, although the diversity of species depends on the size of the gardens and the degree of management. Many scientists in developed countries are beginning to show interest in traditional agriculture, especially in small-scale mixed crop systems, as they search for ways to remedy deficiencies in modern agriculture. Farming systems are usually either small-scale and intensive or more extensive and semi-commercial. Realistically, sustainable agriculture models are needed that combine elements of both traditional and modern scientific knowledge.
