De la norme à la diversité : L'intensification rizicole face à la diversité paysanne dans les périmètres irrigués de l'Office du Niger (Mali)

Abstract : For historical and technical reasons, Sahelian irrigated schemes have constituted very regulated and very standardized entities, in which there is little room for individual initiative. In spite of this, proposed technologies, solely oriented towards rice production, have faced much difficulty being accepted by farmers. The intensive model proposed by Projet Retail in the Office du Niger irrigated scheme is effective and well adapted to the biophysical conditions of the environment. It has nevertheless been adopted by farmers to varying degrees in a variety of ways.

This diversity of responses led to further investigation into the diversity of farm strategies. The issue has been studied using a farming systems approach, taking into account both rice and non-rice activities, as well as a research-development approach closely associating extension agents to the research.

The typology developed clearly shows the importance of non-rice components within the overall operation of farming systems, as well as the sensitivity of Office du Niger farms to external risks. Surveys of farmers' fields indicate that the diversity of farm strategies has consequences for the management of paddy fields, as evidenced by the substantial variability in cultural practices observed. Based on these findings, technical research was initiated to address the problems identified, with care being taken to develop a set of guidelines appropriate for the various existing farming systems and easily applied by extension agents.

The typology has not been limited to a description of the existing situation; it was also used to define actions that take into account the diverse farming systems.. For technical research, it has led to increased emphasis on the development of differentiated intensification models with enhanced flexibility. For rice extension work, it has permitted tailoring extension messages to the objectives and constraints of different farming systems. Also, by showing the importance of non-rice activities within certain farming systems, it has permitted the development of recommenda¬tions regarding gardening and livestock activities, neglected until now. Finally, it provides political and financial decision makers information about measures to take regarding rehabilitation of the scheme, land reallocation, land use planning, social integration, and organizing producers.
