This case study illustrates that new cultivars and labor-based technologies to improve the productivity of the farming systems are available in the region, and that they can be adopted rapidly by large numbers of farmers. The wider and more rapid adoption of yield-enhancing technologies is constrained by the size of the local market and limited effective demand and to some extent by the supply of affordable labor. Furthermore, in many areas of SSA, wars and natural disasters unfortunately seem likely to continue in the foreseeable future. Both potato and sweetpotato will have important roles to play as short-season, nutritious, locally available foods.
