摘要

Worldwide, the utilization of groundwater and its planned use has been an important factor in uplifting productivity of agriculture and ensuring predictability in outputs. Water is essential to bring forth the potential of the land and to enable improved varieties of both plants and animals to make full use of other yield-enhancing production factors. By enhancing productivity, sustainable water management (especially when combined with adequate soil husbandry) helps to ensure better production both for direct consumption and for commercial disposal, so enhancing the generation of necessary economic surpluses for uplifting rural economies. Since the 1960s, global food production has at least kept pace with world population growth, providing more food per capita at generally declining prices, but at a cost to water resources. At the close of the 20th?century, agriculture used a global average of 70% of all water withdrawals, and FAO estimates that global abstractions for irrigation will grow by some 14% by 2030. While this is a much slower rate than experienced in the 1990's, water scarcity stress is projected to grow locally and, in some cases, regionally, constraining local food production.
