Small tank cascade systems in the Walawe River Basin by P. G. Somaratne,Priyantha Jayakody,François Molle,K. Jinapala Pdf

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.

Promise, Trust and Evolution by Rucha Ghate,Narpat Jodha,Pranab Mukhopadhyay Pdf

From land management to water rights, this volume looks at the current status of Common Property Resources, or CPRs, in South Asia. Developed countries, have managed to establish well-defined property rights over numerous resources and in some instances extended non-exclusionary rights over privately owned resources over an extended period of time. In the developing world, however, the share of community property is extensive, either as a response to an expanding market or because the exposure to markets in still in its nascent stage. This coupled with the demands of globalization, has led to the co-existence of both community ownership of resources as well as an evolving private property rights market. This tension between public versus private ownership rights is particularly relevant in the developing countries of South Asia, not only because of its shared history but also because of its resources frequently cross national boundaries. This book tells the story of CPRs and the commons in a rapidly changing South Asia. Including contributions from those working with natural resources in Bhutan, India, Nepal, Pakistan, and Sri Lanka, the papers discuss issues such as equity in distribution; efficiency and productivity of resources; sustainability of resources; and institutional transition and governance.

Multiple-use water services to advance the millennium development goals by van Koppen, Barbara, Moriarty, P., Boelee, Eline Pdf

This research report presents the findings of the first phase of the action-research project "Models for implementing multiple-use water supply systems for enhanced land and water productivity, rural livelihoods and gender equity." Multipleuse water services, or "mus" in short, is a participatory, integrated and poverty-reduction focused approach in poor rural and peri-urban areas, which takes people's multiple water needs as a starting point for providing integrated services, moving beyond the conventional sectoral barriers of the domestic and productive sectors.

Malaria and Land Use by Eveline Klinkenberg,Wim van der Hoek,Felix P. Amerasinghe,Gayathri Jayasinghe,Lal Mutuwatte,Dissanayake M. Gunawardena Pdf

The transmission of malaria in Sri Lanka is unstable; its incidence greatly fluctuates from year to year and exhibits important variations within a year. Identification of the underlying risk factors of malaria is important to target the limited resources for the most-effective control of the disease. This report presents the first results of a project on malaria risk mapping to investigate whether this tool could be utilized to forecast malaria epidemics. It documents the key malaria risk factors for the Uda Walawe region of Sri Lanka, where monthly malaria incidence data were available over a 10-year period. In the study, data on aggregate malaria-incidence rates, land-use and water-use patterns, socioeconomic features and malaria-control interventions were collected and analyzed in a geographical information system. Malaria cases were mapped at the smallest administrative level and relative risks for different variables were calculated employing multivariate analyses. The findings of the study call for malaria-control strategies that are readily adapted to different ecological and epidemiological settings.

Drought Assessment by R. Nagarajan Pdf

Information-based decision-making during drought, often brings out some of the excellent practices that are prevalent in society / individuals. This book is designed to provide information on the drought process, meteorological, hydrological, agriculture, socio-economic aspects and available technologies such as satellite remote sensing data analysis and Geographical Information system for assessment. Assessment procedures utilising the various parameters of importance from various sources for micro level management that would enhance the effectiveness of management practice are dealt in detail. Resource availability and affected group determine the relief assistance for the present event and information that would help them in their realisation and preparedness for the forthcoming years by select countries is highlighted. This would help in the formulation of schemes for event mitigation and area development plans. The readers would gain complete knowledge on drought. This book is expected to act as a guide in preparing people as effective natural resource utilizationist under drought situations.

Small Irrigation Tanks as a Source of Malaria Mosquito Vectors by Felix P. Amerasinghe,International Water Management Institute,Flemming Konradsen,Wim van der Hoek,Priyanie H. Amerasinghe,J. P. W. Gunawardena,K. T. Fonseka,G. Jayasinghe Pdf

Thousands of small irrigation reservoirs (tanks) exist in rice ecosystems in malarious regions of south Asia. The potential of these tanks to generate malaria-transmitting mosquitoes has not been adequately evaluated. Through a study of nine small irrigation tanks in north-central Sri Lanka, this report provides an assessment of the capacity of tanks to generate malaria and nuisance mosquitoes, factors that contribute to mosquito generation, and measures that could ameliorate the problem.

Simulating impacts of irrigation on the hydrology of the Karagan Lagoon in Sri Lanka by Philipp Stanzel,Alexander Öze,Vladimir Smakhtin,Eline Boelee,Peter Droogers Pdf

The extension of the Uda Walawe irrigation scheme in southern Sri Lanka may have a significant ecological impact on the development area and its downstream wetlands. The evaluation of this impact is the subject for a long-term study that is presently being carried out by the International Water Management Institute (IWMI). In this study, the pre- development environmental conditions in the area are being investigated and the changes caused by the new irrigation system will be monitored in the future. Part of this study is a hydrological assessment of the coastal lagoon (Karagan Lewaya) and its small catchment to the south of the evelopment area. The lagoon is likely to receive high quantities of drainage flows from the future scheme. This could deteriorate its water quality and hence affect the suitability of the lagoon as a habitat for migratory birds and might lead to flooding of adjacent settlements.

Small Tanks in Sri Lanka by C. R. Panabokke,International Water Management Institute Pdf

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.
