Cassava has been changing its role as a traditional fresh human food to an efficient crop for animal feeds and starch production. Nearly all cassava productions are conducted by small farmers. Harvested roots are sold to feed mills or starch factories, or used for on-farm feeding of swine to be sold to market. Thus, cassava is an important source of cash income to small farmers in many parts of Asia. International breeding efforts for higher root yield and starch content have been successful and the total area planted with the improved cultivars is now reaching one million ha in six countries in Asia. A substantial portion of economic gain generated by the improved cultivars is entering the household income of small farmers. Cassava often causes soil degradation when proper agronomic practices are not followed. Soil conservation is the prime issue in sustainable cassava production. While individual agronomic methods are important and indispensable components of soil management, a more fundamental requirement is to first upgrade the economic situation of farmers to cut the vicious cycle of poverty and environmental mismanagement. Improved cassava cultivar is one of the most readily adoptable components for inducing better farm management through increased feed or starch production.
