Available in PDF, EPUB and Kindle. Book excerpt: This report on small tank cascade systems is based on a study conducted on seven tank cascades of the Walawe river basin, one of the three main river basins in the Ruhuna benchmark basins selected by the International Water Management Institute (IWMI) for its benchmark basin study.The overall objective of this study is to document the situation of small tank cascade systems in the basin, paying special attention to their evolution under agro-ecological, socio-economic and institutional changes on an unprecedented scale in the country after the introduction of open market economic policies in the 1970s, and thereby to contribute to the existing knowledge on small tank cascades, a key feature of water resources in the Dry zone regions2 of Sri Lanka since time immemorial.

Available in PDF, EPUB and Kindle. Book excerpt: Coping with scarcity of water supply for managing irrigation under uncertain and inadequate conditions has become part and parcel of many irrigation systems in the semiarid tropics of Asia. Based on a case study of the Kirindi Oya Irrigation and Settlement Project (KOISP) in southern Sri Lanka, this report provides evidence of the uncertain and inadequate inflow into the reservoir and its impact on the seasonal planning.

This book was released on 1990-01-01 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is one of several IIMI publications addressing the issue of irrigation management to promote diversified crops during the dry season. As Sri Lanka approaches self-sufficiency in rice production, a target already achieved by some other countries in the region, there is little logic in growing rice using land and water resources which could support higher- value non-rice crops, using less water. Thus, one of the incentives in improving irrigation management is to find ways of stretching water further during the dry season in water-deficit systems, when rice is relatively more expensive to grow than during the wet season, and when other crops which can be grown only during the dry season (when there is less danger of water-logging) offer the farmer and the country a comparative advantage.

Download or read book Multiple Uses of Water in Irrigated Areas written by International Water Management Institute and published by IWMI. This book was released on 1999 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is being transferred out of agriculture to meet the growing demand in other areas, often without an agreement of or compensation to farmers with irrigated land and water rights. Furthermore, there is a failure to recognize that irrigation systems supply water not only for the main fields, but also for domestic uses, home gardens, trees and other permanent vegetation, and livestock. Other productive uses include fishing, harvesting of aquatic plants and animals, and a variety of other enterprises such as brick making. In addition, irrigation systems can have a positive or negative effect on wildlife habitats. Thus, the withdrawal of water affects the rural household, rural economy, and the environment in a number of ways. This paper argues that to ensure efficient, equitable, and sustainable water use, to reduce poverty and improve the well-being of the community, irrigation and water resources policies need to take into account all uses and users of water within the irrigation system. The multiple uses of water in the Kirindi Oya irrigation system are examined in this paper. An interdisciplinary group of scientists have investigated a number of areas including water accounting, water quality, household water use, the valuing of water for alternative uses, and the complementarities, competition, and conflicts among uses and users.

This book was released on 2001 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is based on the Taiwan’s irrigation systems.The first part of this report gives a brief introduction to the Taiwan irrigation systems. Based on the visit and discussions by two IWMI staff members from 25 September to 4 October 2000 with the Association Managers, staff of the Agricultural Engineering Research Centre (AERC) and staff of the Council of Agriculture (COA), certain issues were identified in the two systems, which are detailed. In the second part, the results of analyses of the performance of these two irrgation systems of Taiwan are compared with a irrgation system from Sri Lanka.

Available in PDF, EPUB and Kindle. Book excerpt: The new lands being developed are in various locations in the Dry Zone and have been divided into several systems and projects. The allocation of diverted Mahaweli water to each project for each season is decided by a central Water Management Secretariat. System H is located in the dry zone in the North Central Province of Sri Lanka and is divided into three projects. The water management efforts made to realize this objective, using two different approaches in the H5 subsystem of System H, and the significant results achieved, are discussed in this paper.
