Small tank cascade systems in the Walawe River Basin


Book Description

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.







Perceptions of Tank Cascade Systems in Sri Lanka


Book Description

Researchers have studied various aspects of the ancient civilization of Sri Lanka and probed deeply into the subject of village tank clusters (tank cascade systems) during the last 4 decades. A wealth of information was gathered and the knowledge of many components has been updated. This book brings you this updated information. The author brings new definitions of tank cascade systems and cascade ecology. The book begins with the historical perspective and moves on to explain various aspects, step by step, such as geography, geology and geomorphology, soil and climate, surface and groundwater, traditional agriculture and water management, flora and fauna, recent studies and the restoration of cascade ecology. The book will interest geomorphologists, geologists, geographers, archaeologists, ecologists, and historians. Specifically, university lecturers, students and researchers will find interest in these pages and may utilize the content to prepare their study materials.




Water Communities


Book Description

Water is the key to human civilization. Most of the ancient civilization had its roots to river basins, where people-water interaction was the key aspect. This book offers analytical case studies on different aspects of water communities, which is defined as the human-water interaction process.




Water in a Changing World


Book Description

"The United Nations World Water Development Report", published every three years, is a comprehensive review providing an authoritative picture of the state of the world's freshwater resources. It offers best practices as well as in-depth theoretical analyses to help stimulate ideas and actions for better stewardship in the water sector. It is the only report of its kind, resulting from the collaboration and contributions of the 26 UN agencies, commissions, program, funds, secretariats and conventions that have a significant role in addressing global water concerns.




World Water Assessment Programme Sri Lanka Case Study


Book Description

The Case Study Workshop was organized with the objective of obtaining the necessary input the experts on different subject areas of water resources, subject those views and discussion among the stakeholder agencies, and synthesize the information to a report on the case study. The outcome of the Workshop would eventually transform into the contribution of Sri Lanka to the forst WWDR




Promise, Trust and Evolution


Book Description

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


Book Description

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


Book Description

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.
