extent, significance, and implications for development
GIAHS are found throughout the developing world, linked to centers of diversity. Agroecosystems cover more than one quarter of the global land area, reaching about 5 billion hectares. Agroecosystems are ecosystems in which people have deliberately selected crop plants and livestock animals to replace the natural flora and fauna.
