Topic 23: Modeling interactions between water management, farm management and agrifood supply chains management at scheme level. Case study in Morocco Sustainability of collective irrigation schemes depends on the capacity of scheme managers to deliver an efficient water service to farmers, and of farmers to pay for this service based on the incomes they get from the marketing of their irrigated productions. This marketing process depends itself on the opportunities provided by agri-food supply chains intervening in the scheme. Some of these supply chains concern processing products, such as milk or sugarcane, which are managed by processing companies. Others concern fresh products, such as fruits and vegetables, and usually involve a large range of collectors, including supermarkets. Several supply chains may be present in a given scheme. Then they compete at farm level in relation with the strategic decisions made by farmers and the water allocated to each production (see figure below). Coordination processes between stakeholders are usually fragmented: on one side between scheme manager and farmers for water allocation, on the other side between farmers and collectors / processors for raw material supply. The absence of overall coordination at scheme level between the three kinds of stakeholders can lead to inefficiencies regarding the use of water resource, the regularity of raw materials supplied both in quantity and quality, and in fine stakeholders’ incomes. This proposal aims to (i) analyze on a given scheme the interactions between these three stakeholders, (ii) design and develop a computerized model that would enable to test various scenarios of resource allocation (water, land, income) taking into account the diversity of stakeholders’ objectives and strategies, and (iii) simulate and discuss various scenarios of coordination that could improve the total income generated by the scheme while satisfying stakeholders’ objectives. The methodology would be based on former works conducted in Brazil for water management (de Nys et al., 2008), La Réunion and South Africa for sugarcane (Lejars et al., 2008, Le Gal et al., 2008) and Morroco for dairy chain (Le Gal et al., 2007; Le Gal et al., 2009). It is proposed to conduct the research - intervention on a scheme in Morocco, still to be selected according to the potential partnership of this study (IAV Hassan II + European teams). Supervised by SupAgro and Catania. (translated from Le Gal, 2006) References De Nys E., Le Gal P.-Y., Raes D., Ana E., 2008.
