Subsurface drainage resulting from irrigated agriculture is a toxic threat to fish and wildlife resources throughout the western United States. Studies by the U.S. Department of the Interior show that migratory waterfowl have been poisoned by drainwater contaminants on at least six national wildlife refuges. Allowing this poisoning to continue is a violation of the Migratory Bird Treaty Act und...

Given the current demographic trends and future growth projections, as much as 60% of the global population may suffer water scarcity by the year 2025 [9]. In addition to water scarcity, water quality deterioration is expected to intensify in resourcepoor countries in dry areas, due to human activity and climate change. It is projected that water scarce countries will have to increasingly rely ...

There is a gradual decline in soil fertility due to its continue use in farming. This necessitates developing new strategies of management programs to recharge soil with nutrients. From review it has been found that reuse of industrial effluents (wastewater) in agriculture can be a good mode to conserve soil nutrients. It may offer a way to fulfill irrigation water demands also. The major chall...
