Poverty reduction is the first priority of SADC, and ZAMCOM has a primary goal of poverty reduction through the shared water resource. ZAMCOM must address the concerns of downstream users over extraction of water upstream. Thus Mozambique is concerned that its prawn industry in the Zambezi delta is not affected by reduced flows, and that the Cahora Bassa hydroelectric plant receives sufficient water.
