Some upland areas in Southeast Asia have relatively favorable climatic conditions that allow more intensive agricultural use, especially where the communities are also better integrated into the market economy. Permanent cultivation systems that are commercially oriented prevail in these areas. The use of relatively higher input levels is not a major constraint to maintaining agricultural productivity. Therefore, increasing the efficiency of these inputs and reducing negative environmental effects are important goals for research. Working Group 6 has involved farmers in its research program in order to address their needs in improving crop production for household food security. Seed health, disease resistance, improved weed management, and access to seeds are important outcomes from discussions with farmers.
