| Underground and surface water as a result of human activity are increasingly polluted. Mainly due to improper disposal of waste, discharge of effluents, among other actions that compromise the environment. The water analysis is necessary to determine and evaluate the situation of water supply to the population. This study evaluated the supply situation of three rural communities located in the south of Brazil, where the water is carried out through the abstraction of groundwater. Pastures, fields and remnants of native vegetation characterize the region. The water quality used to supply was what motivated the accomplishment of this work. The wells are unprotected in the middle of the pastures near to black cesspits and crops that use frequently... |

| Esta investigación tuvo como objetivo formular estrategias y escenarios para el abastecimiento de agua para consumo humano, uso doméstico y productivo, considerando las condiciones socioculturales, económicas y modos de producción; con el propósito de identificar tecnologías que atienden las demandas actuales y futuras en materia de agua en la entidad del DF y Estado de México. Se inició con el diseño de cinco escenarios de caso: casa rural marginada, urbana, residencia, mediana industria e industrial, pero solo se transfirió la residencia y mediana industria. En el escenario de la zona residencial la integración de captación y el tratamiento biológico de aguas residuales genera ahorros de 20.92 por ciento anual. En la mediana industria la integración de... |

| The irrigation performance of any irrigation systems is highly facilitated when using a fitted model to represent the measured data. Several statistical distribution models, such as uniform, normal, lognormal, specialized power, beta, and gamma, have been used to fit applied water from irrigation, as na aid to evaluate the irrigation performance. However, the goodness of fitting the model to the observed values is very important to warrant reliable results. The purposed model resembles a power function and has desirable flexibilities for adjusting data. It uses four adjusting parameters, conferring to the model a great deal of power to adjust a variety of possible shapes of normally found distribution profiles from water irrigation applications. Its... |

| This paper gives a brief discussion on water supply from wetlands in Tanzania. The majordrainage basins in Tanzania are described and the status and role of the Division of WaterResearch in the monitoring of water resources and data collection from wetlands and watersources are highlighted. The role of wetlands in the hydrological cycle, and the utilisation ofwetlands as water supply sources are discussed. The need for conservation and protection ofwetlands and other water sources is outlined. |

| The paper discusses the application of the Water Poverty Index (WPI) as a monitoring tool for Benin’s water sector. Benin is currently in a process of political decentralization shifting responsibility for and administration of rural water supplies from the national to the communal level. Appropriate indicators are needed for monitoring and analyzing the progress of the water sector for each community. The Water Poverty Index allows monitoring of a combination of aspects affecting rural water management, including water sources, access to and use of water, human capacity to manage water, and environmental impacts. The application of this index is tested for Benin at the regional level. A series of variables have been chosen for inclusion into the index... |

| Water availability in semiarid regions usually exhibits patterns of extreme variability. Even in intensively controlled basins, some users are subject to low levels of water reliability, and more vulnerable to periods of extreme scarcity. To reduce their risk exposure more flexible instruments, such as voluntary exchanges of water among users, are required. Recent changes in the Spanish water Law have given an initial impulse to allow for leases of water use rights. Properly designed and monitored, this instrument provides some flexibility to water management, and may increase the economic use efficiency as well as mitigate the adverse economic effects of droughts. This paper looks at the risks and uncertainty dimensions of water markets, which have not... |

| With a rapidly expanding economy many changes are taking place in India today. The business-as-usual (BAU) scenario, which assumes the continuation of current trends of key water demand drivers, will meet the future food demand. However, it leads to a severe regional water crisis by 2050, where many river basins will reach closure, will be physically water-scarce and will have regions with severely overexploited groundwater resources. While the alternative scenarios of water demand show both optimistic and pessimistic water futures, the scenario with additional productivity growth is the most optimistic, with significant scope for reducing future water demand. |
