Promising Strategy

Cadmium (Cd) and arsenic (As) accumulation in rice grains is a great threat to its productivity, grain quality, and thus human health. Pot and field studies were carried out to unravel the effect of different water management practices (aerobic, aerobic-flooded, and flooded) on Cd and As accumulation in rice grains of two different varieties. In pot experiment, Cd or As was also added into the soil as treatment. Pots without Cd or As addition were maintained as control. Results indicated that water management practices significantly influenced the Cd and As concentration in rice grains and aerobic cultivation of rice furnished less As concentration in its grains. Nonetheless, Cd concentration in this treatment was higher than the grains of flooded rice. Likewise, in field study, aerobic and flooded rice cultivation recorded higher Cd and As concentration, respectively. However, growing of rice in aerobic-flooded conditions decreased the Cd concentration by 9.38 times on average basis as compared to aerobic rice. Furthermore, this treatment showed 28% less As concentration than that recorded in flooded rice cultivation. The results suggested that aerobic-flooded cultivation may be a promising strategy to reduce the Cd and As accumulations in rice grains simultaneously.

N Management

Efficient N management practices usually involve many potential strategies, but always involve choosing the correct amount of N and the coupling of N management to efficient water management. Nitrogen management strategies are integral parts of improved production practices recommended by land-grant universities such as the Institute of Food and Agricultural Sciences, Univ. of Florida. This paper, which draws heavily on research and experience in Florida, outlines the concepts and technologies for managing vegetable N fertilization to minimize negative impacts on the environment.

Individual Use

Economic incentives are used in many situations to motivate improvements in the use of scarce resources. In some areas, implementing appropriate incentives is made challenging by the nature of existing institutions or the inability to assign property rights and measure individual use of key resources. Higher prices for irrigation water can motivate wiser use of water in regions where the opportunity cost of water is rising, due to increasing municipal, industrial and environmental demands. This paper describes how an increasing block-rate pricing structure was designed and implemented in an irrigation district in central California. The goals of the program were to improve water management practices and reduce the volume of subsurface drain water discharged into the San Joaquin River. Results describing reductions in average irrigation depths and drain water volumes, collected throughout the 1990s, demonstrate the potential for achieving resource management goals with economic incentives that motivate changes in farm-level management practices. Complementary incentive programs and issues regarding program implementation and the sustainability of drain water reduction efforts in an arid region also are discussed.

Management Plans

Restoration and enhancement of Lake Okeechobee and the Florida Everglades requires a comprehensive approach to manage agricultural runoff. The Florida Surface Water Improvement and Management (SWIM) Act of 1987 was promulgated to develop and implement plans for protecting Florida waters. The South Florida Water Management District was directed by Florida legislature to develop management plans for Lake Okeechobee (SWIM) and the Everglades ecosystem (Marjory Stoneman Douglas Everglades Protection Act of 1991). These plans require agriculture to implement best management practices (BMPs) to reduce runoff phosphorus (P) loads. The Lake Okeechobee SWIM plan established a P load reduction target for Lake Okeechobee and set P concentration limitations for runoff from non-point source agricultural sources. Agricultural water users in the Everglades Agricultural Area (EAA) are required to develop farm management plans to reduce P loads from the basin by 25%. The Everglades Forever Act of 1994 additionally emphasized linkage of these landscapes and consequent protection and restoration of the Everglades. Agricultural BMPs are being developed and implemented to comply with water management, environmental, and regulatory standards. Although BMPs are improving runoff water quality, additional research is necessary to obtain the best combination of BMPs for individual farms. This paper summarizes the development of comprehensive water management in south Florida and the agricultural BMPs carried out to meet regulatory requirements for Lake Okeechobee and the Everglades.

A multi-disciplinary analysis of the evolution of water politics and policy by an international team of distinguished experts. Water management in the Middle Ages in Europe, its evolution in the USA, the elaboration of the European Water Framework Directive, the British experience of water management, the over-exploitation of African aquifers, and the evolution of the water situation in Southern Africa are all examined. This volume underlines the fact that only an integrative and interdisciplinary understanding can lead to genuinely improved water management practices that will not benefit some social groups at the expense of others.
