Book Description
India's irrigated agriculture sector has been basic to India's economic development and poverty alleviation. One of India's major achievements is its rapid expansion of irrigation and drainage infrastructure. However, the major emphasis on development has been achieved at a cost. The importance put on new construction has diverted attention away from the need to ensure the quality, productivity, and sustainability of the services. Further, a governmental subsidy based approach has been used and this has resulted in irrigation and drainage services which, while enabling significantly higher productivity than from non-irrigated lands, are well below their potential. 'The Irrigation Sector' discusses directions for future growth, the framework for reform, and the reform agenda.

Book Description
Using a variety of research findings and case studies, this publication provides a broad picture of water quality and quantity in Canada as they are affected by agriculture and as they affect agriculture itself. The first part contains background on the water cycle, water supplies in Canada, agriculture & other rural uses of water, and issues related to water quality. The second part describes what is currently known about the health of Canada's rural surface water and groundwater, and the implications for natural ecosystems. The third part describes responses to the various issues of water quality & quantity, citing farming practices and regulatory tools, among other measures. The final part discusses how the growth of agriculture may be limited by issues related to water and how the future might proceed. Includes glossary.

Book Description
The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.
