Water Allocation Among Multiple Uses Using Interactive Decision Maps

Alqueva dam in the Alentejo Region was developed to solve water scarcity in the South of Portugal and to ensure permanent availability of water for household and industrial consumption, irrigation, production of electric energy, and ecological and environmental purposes. Competition among some of these multiple water uses requires an integrated management framework. This paper uses Interactive Decision Maps (IDM) technique to explore and achieve efficient and equitable water allocation combinations taking into account those multiple goals and principles of good water governance.
