La culture du manioc en zone soudanienne du Tchad, contribution à la sécurité alimentaire et aux revenus des agriculteurs

Abstract : The cassava was introduced in Chad in 1930. The agronomic characteristic of this crop and the simplicity of its technical operations were facilitated its adoption and distribution in all of the Sudanian zone of Chad. During the 1990s, the conflicts between farmers and stockbreeders slowed down the cultivated areas. In early 2000s, favorable factors restarted the cultivation of crop. The productivity of the Chadian agriculture and the weakness of the prices of agricultural products do not allow the farmers to cover their food needs and to have satisfactory incomes. That is why the cassava cultivation thus considered by many actors as one of the most credible alternatives to cover the food-shortage, deaden the shocks annually taken by the small farmers and to stimulate an agricultural development process. Our study aimed to appreciate the part played by cassava in the farmer’s system and particularly its contribution in the farmer’s food supply and incomes. Farming system research methods were used to analyze farmer’s practices. The agricultural network analysis methods were used to study the marketing’s practices. Our study highlighted the leading role of the cassava as well as source of income and as a main contributor in the food supply for the farmers. However, some factors may be constraints for the development and durability of the current farmer’s production systems. Firstly, the currently cassava derived products are not very elaborate and cannot make a cassava a truly commercial crop directed towards to the urban markets. Then the current productivity of the cultivation systems cannot be maintained in the medium term if the cultivation methods dot not evolves. At last the conflicts between farmers and stockbreeders appear among the constraints which must be raised to allow harmonious development of cassava cultivation.
