چکیده مقاله:

Agricultural water has helped meet fast-rising demand for food and has contributed to the growth of agricultural profitability and poverty reduction as well as to regional development and environmentalprotection. However, after several decades of publicly funded surface irrigation, and more recently ofprivately developed groundwater irrigation, opportunities to harness new resources for agriculture are fewer and more expensive. Investment is increasingly focused on rehabilitating and improving existingsystems. However, water productivity remains generally low and returns to public investment have beengenerally disappointing, especially in large-scale irrigation LSI . New solutions are needed, based on new management options and widely available technologies. How to meet ever rising demand for food,while at the same time increasing farmer incomes, reducing poverty, and protecting the environment— allfrom an increasingly constrained water resource base—is the main challenge facing agricultural watermanagement AWM . Governments have taken up the expansion of LSI, but performance has been suboptimal. Despite strong investment and management input from governments, the supply driven approaches and LSI infrastructure that were to fuel growth have often resulted in bureaucratic institutions, lacking the structure and incentives for efficient management, and in inflexible water delivery systemsincapable of responding to farmer needs
