There is a historical association between wetlands and infectious disease that has led to the modification of wetlands to prevent disease. At the same time there has been the development of water resources projects that increase the risk of disease. The demand for more water development projects and the increased pressure to make natural wetlands economically beneficial creates the need for an ...

The prediction of hydrological dynamics is an important issue in the scientific community of hydrologists and modellers and essential for integrated water resources decision support. However, the utilization of hydrological models in regions with no or a limited amount of measured data is restricted. Remote sensing techniques provide the means to derive such information, e.g. land cover or soil...

The efficient control of water usage is one of the core goals of the strictest water resources management system in China. Therefore, the objective and reasonable evaluation of the effects of implementing this system is crucial. Based on the natural and social water cycle theories and the mechanism of the influence of agricultural, industrial, domestic and ecological water utilization, this pap...

This paper reviews the importance of African lakes and their management challenges. African inland lakes contribute significantly to food security, livelihoods and national economies through direct exploitation of fisheries, water resources for irrigation and hydropower generation. Because of these key contributions, the ecosystem services provided are under significant stress mainly owing to h...

The Eastern Mediterranean Region of the WHO is the poorest region in the world in water resources as a Region and per capita. This paper summarizes existing practices and constraints regarding wastewater treatment and reuse in the Region and describes the health impact of inappropriate practices. Appropriate treatment for agricultural use from the health point of view, and the health regulation...

There has been very limited research on water use efficiency for soil conservation (WUE-SC) in typical water scarce regions such as the lower Heihe River Basin, where there is serious wind erosion and the soil conservation service plays a key role in guaranteeing the ecological safety of Northern China. The soil conservation service, which was represented by the soil conservation amount (SC), w...

Scarcity of water in the world, virtually, has two sources: the quality and the quantity made available for populations. In the area covered by this study, the selected municipalities from the river basins 3 e 4 of the Paranapanema River and from the basin of the Pirapó River, availability is always greater than the demand and the environmental problems are more often linked to the quality than...

Himalayan glaciers are a focus of public and scientific debate. Prevailing uncertainties are of major concern because some projections of their future have serious implications for water resources. Most Himalayan glaciers are losing mass at rates similar to glaciers elsewhere, except for emerging indications of stability or mass gain in the Karakoram. A poor understanding of the processes affec...

A unique model of resources consumption drag of urbanization is developed by employing the neo-classical production model and the urbanization relation model. By using this model, it is viable to estimate the resources consumption drag, measured as the reduced speed of urbanization from resources consumption and environmental services. In terms of reduced urbanization process, the aggregated an...
