Construction de la demande en eau agricole au niveau régional en intégrant le comportement des agriculteurs. Application aux exploitations agricoles collectives de la Mitidja-Ouest (Algérie)

Abstract : A territory's integrated water management must take into account the demand of users. In irrigated agriculture, water demand is a social construction determined by both needs of crops and by supply, but as well as by farmers' constraints. In the absence of strong institutions that can recognize these constraints, it is difficult to establish beneficial rules of management for all. In the irrigated plain of Mitidja-west (Algeria), our work focussed on integrating farmers' points of view into the construction of agricultural water demand and its evolution. An innovative methodology was developed based on a combination of approaches, constituted of: a water balance calculation; a technical and economic water analysis; and a participatory method involving a variety of stakeholders (farmers and institutional representatives). Irrigated agriculture in the Mitidja-west is characterized by collective operational structures (the EAC) and a massive use of ground water resources. A great diversity of cultures and practices were observed in individual field investigations. These investigations revealed the relative importance of tenants in new modern agricultural dynamics. Despite this diversity, the implementation of participatory sessions revealed a convergence of farmers' views on the constraints of the land and irrigation water burdens, as well as their visions for the future. These constraints and this vision were confronted with those of institutional stakeholders of the same territory. The method built, allowed both a validation of the results of the individual investigations collectively with the stakeholders and a shared vision to be created about trend scenarios, such as increasing irrigated areas. Several scenarios were tested based on these trends. Nevertheless, their validation requires additional research to further control diversity and communication between the approaches that were mobilized. This work has been undertaken as action research on the Mitidja plain (Algeria), in order to enable communication between stakeholders and reflection on the long term.
