Theib Oweis, Ahmed Hachum. (1/1/2006). Investment note 6. 1 - Investing in Supplemental Irrigation, in "Shaping the Future of Water for Agriculture: A Sourcebook for Investment in Agricultural Water Management". United States: The World Bank - WB.
Supplemental irrigation helps stabilize rainfed agriculture. For the greatest benefit, it must be part of an integrated package of farm cultural practices. Overexploitation of groundwater threatens the sustainability of groundwater-based supplemental irrigation in many areas. Supplemental irrigation that is optimized through on-farm water management policies and timely socioeconomic interventions is essential for the sustainable use of limited water resources.
