This Reports outlines the institutional framework for cooperation and some institutional capacity support initiatives. It examines (1) a first level of cooperative mechanisms (that of coordination), noting that data and information sharing will be a key to successful basin-wide development; (2) the organizational implications of data and information sharing and its role in project planning, monitoring and evaluation, strategic planning and policy review (in the context of ENCOM, ENSAPT and ENTRO); (3) the cooperative mechanisms required for an increased level of cooperation (i.e., for Collaborative Activities); and (4) the cooperative mechanisms required for joint long term activities that would require permanent institutional and organizational arrangements.
