IRRIGATION Management Institute (IIMI) and the Tropical Agriculture Research Center (TARC), Ministry of Agriculture, Forestry and Fisheries of Japan, initiated a collaborative study in August 1991. This joint study is focused on small-scale tank irrigation systems which are spread over the Dry Zone of Sri Lanka, and is conducted with the assistance of Sri Lanka's Department of Agrarian Services

The core of this study involved an examination and analysis of certain key features of the traditional small tank cascade systems: a) the location and design of the systems in the past b) the hydro-system which considers the overall hydrological balance and groundwater conditions c) maintenance and tank use d) tank management and integration with local farming systems.

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.

Village irrigation systems (ViSs) are vital in rural livelihood, food, and water security. VISs include small (minor) tanks and diversions (anicuts). The hydrologically linked tanks with natural drainage patterns form cascades, and beyond food and water security, they play a significant role in mitigating flood and drought impacts on communities in river basins. With anthropogenic changes, many cascades are in depilated states now. This paper finds that policy support with legal recognition to cascade-based community-level institutions promote bottom-up water and natural resources management approaches. They also facilitate investigations of ill-defined subject areas in cascade management and complex socio-political and economic issues and challenges constraining sustainable cascade based VISs operations.
