VIANA

Irrigated agriculture is a major feature of the Mediterranean basin, and has expanded tremendously in the past decades, through access to a previously untapped resource, groundwater. Within the perspective of global challenges linked to food security, poverty alleviation, natural resources degradation in conjunction with climate change, rural development and migration patterns, irrigated agriculture is of vital importance to maintain viable farming systems within the Mediterranean basin. In addition to the imminent threat of groundwater depletion, small-scale irrigated farming systems face vulnerabilities such as soil degradation, unequal access to productive resources and difficult access to markets and information. The project VIANA (Vulnerabilities et adaptive capacities of Irrigated Agriculture in North Africa) extends previous research on vulnerabilities of irrigated agriculture in North Africa, by characterizing potentially existing local agroecological solutions and understanding the context in which such practices have emerged or been adopted. Using the lens of vulnerability and adaptive capacity, and assuming that, locally, strong capacities of adaptations and innovations developed by farmers exist, the objective of this project is to identify, characterize and co-evaluate existing adaptations and lower-input systems developed by actors at different scales (plots, farms and irrigated territory) to deal with these vulnerabilities. The project will, in particular, focus on characterizing local farming practices with a potential to maintain overall productivity of irrigated territories while improving environmental sustainability, focusing in particular on on-farm improved efficiency of input uses, water efficient cropping systems, and crop-animal diversification strategies. The project involves three contrasted groundwater-irrigated territories in North Africa: the Saïs plain in Morocco, the Haut-Chéliff plain in Algeria, and the Kairouan plain in Tunisia. From a methodological point of view, the project is resolutely transdisciplinary, and will include researchers in agronomy, water and environmental sciences, economy and political science. All these disciplines will contribute to qualify the socio-ecological system of irrigated agriculture within an interdisciplinary cognitive framework. It is also problem and action-oriented and participatory, with an emphasis on social learning, through the inclusion of farmers and institutional actors in major steps of the project. Involving six young researchers from four Mediterranean countries, in various fields of knowledge, VIANA will contribute to forming a new generation of researchers interested in apprehending challenges around irrigated agriculture, in a transdisciplinary and participative approach. In parallel, it will contribute to improve farmers’ knowledge on environmental impacts of agriculture through both the social learning process and a better understanding of their roles and actions in the research arena.
