The outcome of the Workshop would eventually transform into the contribution of Sri Lanka to the forst WWDR




World Water Assessment Program Case Study, Ruhuna Basins, Sri Lanka


Book Description

The "Ruhuna Basins" defined for this case study encompass three of the main rivers that flow through ancient Ruhuna, including the longest and most important river in the region, Walawe. The Ruhuna basins are important in the broader Sri Lankan context, the basin being the location of a major hydropower plant, irrigation schemes that make a significant contribution to national food production, and important nature reserves. However, even before the proposed development begins to be implemented, the basins are experiencing major water resources problems, clearly demonstrated by the recent drought that led to reduction of water supplies to agriculture, insufficient domestic water supply, and which contributed to nationwide power cuts up to 8 hours a day. These challenging issues motivated the Government of Sri Lanka to select the cluster of three important rivers, Walawe, Menik and Kirindi, and the smaller basins confined by them as the area for the case study for the World Water Assessment Program.




The United Nations world water development report 2015: water for a sustainable world


Book Description

The United Nations World Water Assessment Programme (WWAP) is hosted and led by UNESCO. WWAP brings together the work of 31 UN-Water Members as well as 37 Partners to publish the United Nations World Water Development Report (WWDR) series. Under the theme Water for Sustainable Development, the WWDR 2015 has been prepared as a contribution from UN-Water to the discussions surrounding the post-2015 framework for global sustainable development. Highlighting water's unique and often complex role in achieving various sustainable development objectives, the WWDR 2015 is addressed to policy- and decision-makers inside and outside the water community, as well as to anyone with an interest in freshwater and its many life-giving benefits. The report sets an aspirational yet achievable vision for the future of water towards 2050 by describing how water supports healthy and prosperous human communities, maintains well functioning ecosystems and ecological services, and provides a cornerstone for short and long-term economic development. It provides an overview of the challenges, issues and trends in terms of water resources, their use and water-related services like water supply and sanitation. The report also offers, in a rigorous yet accessible manner, guidance about how to address these challenges and to seize the opportunities that sound water management provides in order to achieve and maintain economic, social and environmental sustainability.

Impacts of climate change on water resources and agriculture in Sri Lanka: a review and preliminary vulnerability mapping.


Book Description

There is ample evidence to suggest that Sri Lanka’s climate has already changed. However, the bigger question of national importance is what Sri Lanka’s climate will look like in 50 or 100 years and how prepared the country is to face such changes. This report reviews the status of climate change (CC) research/activities in Sri Lanka in terms of observed and projected climatic changes, their impacts on water resources and agriculture, CC mitigation and adaptation, and research needs. The study also developed a pilot level CC Vulnerability Index, which was subsequently mapped at district level. The maps indicate that typical farming districts such as Nuwara Eliya, Badulla, Moneragala, Ratnapura and Anuradhapura are the most vulnerable to CC due to their heavy reliance on primary agriculture.




Climate Change Research at Universities


Book Description

This unique book provides a multidisciplinary review of current, climate-change research projects at universities around the globe, offering perspectives from all of the natural and social sciences. Numerous universities worldwide pursue state-of-the-art research on climate change, focussing on mitigation of its effects as well as human adaptation to it. However, the 2015 Paris 21st Conference of the Parties of the United Nations Framework Convention on Climate Change (UNFCCC) (COP 21)” demonstrated that there is still much room for improvement in the role played by universities in international negotiations and decision-making on climate change. To date, few scientific meetings have provided multidisciplinary perspectives on climate change in which researchers across the natural and social sciences could come together to exchange research findings and discuss methods relating to climate change mitigation and adaption studies. As a result the published literature has also lacked a broad perspective. This book fills that gap and is of interest to all researchers and policy-makers concerned with global climate change regardless of their area of expertise.




Impact of Climate Change on Hydrological Cycle, Ecosystem, Fisheries and Food Security


Book Description

Climate change has emerged as the most pressing global challenge of the 21st century and it has a dramatic effect on natural ecosystems and environment. Intelligent mitigation strategies to minimise climate change impacts can result in advanced, novel technologies; healthier aquatic ecosystems and higher food security and well-being for humans. The book includes 45 Chapters by expert authors, covering (i) Hydrometeorology and hydrology, (ii) Natural hazards and disaster risk management, (iii) Aquaculture, (iv) Changing biodiversity scenarios, (v) Capture fisheries, (vi) Food and nutritional insecurity, (vii) Climate change and socio-economic scenarios, and allied areas. It is hoped that this volume will further our understanding and research achievements in the field of climate change and its consequences and facilitate the synthesis of information on how climate-related changes will influence oceans, marine and inland ecosystems, hydrological cycles, fisheries and aquaculture and coastal communities and will be immensely useful to planners, scientists, conservationists, environmentalists, academicians, students and all those who are directly or indirectly involved in the study of impact of climate change and mitigation measures Note: T& F does not sell or distribute the Hardback in India, Pakistan, Nepal, Bhutan, Bangladesh and Sri Lanka.




Balancing irrigation and hydropower: Case study from Southern Sri Lanka


Book Description

This report analyzes a case from southern Sri Lanka, where the Samanalawewa dam and the Kaltota Irrigation Scheme (KIS) compete for the water of the Walawe river. At the catchment level, it is shown that dam releases are well attuned to the needs of KIS and to the occurrences of natural runoff, and that little of the dam water is "lost" to the river.




Livelihood Enhancement Through Agriculture, Tourism and Health


Book Description

Agriculture is the backbone of our economic system. It provides not only food and raw material but also employment opportunities to a very large number of people. Higher atmospheric temperature has an impact on crop yields while the changes in rainfall could affect both crop quality and quantity. Climate change, therefore, could increase the prices of major crops in some regions. For the most vulnerable people, lower agricultural output means lower income. In addition, climate change is expected to increase the risk of illness and death from extreme heat and poor air quality. Recent evidence is the COVID-19 pandemic. Furthermore, climate change also affects the occurrence of other infectious diseases. A number of well-known diseases are climate-sensitive - malaria, dengue fever, and cholera among others. Tourism is considered as an industry and alternative contributor to a nation’s income. It can generate employment opportunities and boost up the economy. This book, consisting of 26 chapters, focuses on the issues of agriculture, tourism and health for livelihood enhancement. It is essential to discuss these diverse issues in the field of geography as it encompasses interdisciplinary topics. The range of concerns at the national, regional and local levels is not confined to geography only but also involves other disciplines as well. Therefore, this book is a valuable source for scientists and researchers in allied fields such as livelihood, agriculture, land use, tourism management, health care and tribal studies. Furthermore, this book can be of immense help to the researchers, planners and decision makers engaged in solving problems in these areas in developing countries and beyond.
