Two water allocation models were developed in this project as a tool to support policy evaluation and improve strategic and operational decision making procedures of ARA-Sul, which is one of the five water management organizations in Mozambique. WEAP (Water Evaluation And Planning) was chosen as modelling framework. Different scenarios were implemented in WEAP to show the impacts of possible changes and the effects of possible adaptation measures. In order to interactively teach the ARA-Sul staff to apply and extend the developed models, several training missions were undertaken.
