Multiple Criteria Decision Making methods have shown their efficiency in the last years as a powerful tool to help decision makers and governments in the process of planning and/or implementing technical solutions to real problems that affect local populations. In this regard, we present some recent applications that we have carried out in collaboration with local administrations of developing countries, and with funds of the Spanish Agency of Cooperation and Development. We start with a complex water distribution problem de- scribed through a bicriteria fair division model over time with network constraints in the region of Kabylia, Algeria. Following, we provide a model for the multiobjective management of the Kwanza river, in Angola. The problem is complicated by the need to take into account uncertainty in various involved processes, to plan over a long period of time, and the presence of several conflicting interests. Finally, we present an approach for identifying optimum adaptation strategies for agricultural land management with respect to multiple ecosystem services. These include not only food production but also water regulation, soil protection and nutrient cycling. The methodology is to be applied to identify optimum land management patterns in different African countries.
