Download or read book Anicut systems in Sri Lanka The case of the Upper Walawe River Basin written by François Molle and published by IWMI. This book was released on 2003 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: This exploratory study was designed to capture the main features of agrarian change in the upper part of the basin that depends mostly on anicuts. These anicuts amount to 59 percent of the total basin anicuts in terms of numbers, but to only 43 percent in terms of irrigated area. They are generally very old (the history of some of them goes back to 2000 years; see below) and obviously, many changes have occurred during this time. The study does not allow the reconstitution of all past transformations but offers some insight on recent changes: changes in population pressure over resources and changes in hydrology, crop choice, livelihoods and collective action. The analysis is based on exploratory surveys carried out by the authors and by students of the University of Sabaragamuwa and is not a detailed or in-depth investigation of agricultural systems in the Upper Walawe basin. However, it provides a useful outline of the situation in this part of the basin.

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.
