Popis:	Improving water productivity is one important strategy for addressing future water scarcity, which is driven particularly by increasing human population and potential climate and land use changes. Although an understanding of water productivity is required to develop improved water management strategies, little is known about it in irrigated systems of the sub-Saharan Africa. This study assesses the physical crop water productivity at farm and scheme scales for two distinct systems: a medium and small reservoir in semi-arid environment of the Upper East Region in Ghana. The study concludes that water productivity for the study reservoirs is low, and that potential for improvement exists through improved irrigation water management and agronomic practices.
