Some states are located entirely within the area of one BC. In other cases, where a state is divided between two or more BCs, the state participates in all the BCs within its territory. To date, two RBCs have been implemented and ANA is carrying out programmes to stimulate the creation of councils in ten additional basins, while tackling remaining challenges such as financial sustainability, capacity building regarding negotiation and consultation, civil society representation and the long-term contribution of RBCs to national development.
