Wastewater Use in Irrigated Agriculture: Management Challenges in Developing Countries
Cities in developing countries are experiencing unparalleled growth and rapidly increasing water supply and sanitation coverage that will continue to release growing volumes of wastewater. In many developing countries, untreated or partially treated wastewater is used to irrigate the cities’ own food, fodder, and green spaces. Farmers have been using untreated wastewater for centuries, but grea...
متن کاملConfronting the Realities of Wastewater Use in Irrigated Agriculture: Lessons Learned and Recommendations
This concluding chapter synthesises results and lessons learned throughout this volume, which deals with the reality of wastewater use in agriculture in developing countries. It then extrapolates from these lessons, to make pragmatic recommendations aimed at protecting both the public health and farmers’ livelihoods. Addressing these lessons in a significant fashion is becoming ever more necess...
متن کاملPrincipals of Reusing Municipal and Industrial Wastewater Discharges for Irrigated Agriculture
Many regions around the world are currently facing water shortages which inhibit development and economic growth. Although some of the allocation problems faced by these regions can be partially alleviated by improving agricultural irrigation efficiencies, another means for substantial water savings involves the reuse of municipal and industrial discharges to offset freshwater demands. In many ...
متن کاملChallenging Conventional Approaches to Managing Wastewater Use in Agriculture
In developing countries urban wastewater management often fails to cope with increasing wastewater generation. Financial, technical and institutional limitations force authorities to discharge substantial amounts of untreated or partially treated wastewater into surface waters. Consequently, uncontrolled use of polluted water is increasingly common in the downstream peri-urban areas. Although w...
متن کاملControlling nitrate leaching in irrigated agriculture.
The impact of improved irrigation and nutrient practices on ground water quality was assessed at the Nebraska Management System Evaluation Area using ground water quality data collected from 16 depths at 31 strategically located multilevel samplers three times annually from 1991 to 1996. The site was sectioned into four 13.4-ha management fields: (i) a conventional furrow-irrigated corn (Zea ma...
