Efficiency improvements across all water using sectors can have a major impact on overall water use efficiency. Various methods can be used to improve water management practices across sectors. In the industrial sector, for example, recycling can improve efficiency and lead to substantial water savings. Beekman (1998) suggests that in many industries, water use could be reduced by around 50% as a result. Cooling water is one area that could potentially lead to major savings, as it makes up around half of current industrial water use.
Water scarcity is a significant constraint to cereal production growth. Rosegrant et al. (2002) project that for the base year of 1995 grain harvests in developing countries fell short by 90 million mt as a result of water shortages. By 2025, the production shortfall is expected to grow to 296 million mt under business-as-usual conditions and to a much higher 440 million mt if investments in agricultural research and water infrastructure slow even more. 20 M.

Studies conducted by Shah et al. (2003), Takeuchi and Murthy (1994) and Llamas et al. 8). India had the largest extraction rate at 150 km3 of groundwater utilized during the 1980s. This is not surprising, as 60% of Indian irrigated food grain production depends on groundwater from wells. The United States was the second largest groundwater user at 101 km3; half the population in the United States draws its domestic water supply from groundwater (Morris 1997). In China, both population and economic activity have grown significantly during the last 25 years and much of this development has depended heavily on groundwater resources (Foster and Garduño 2004).
