The Mekong is the most controversial river in Southeast Asia, and increasingly the focus of international attention. It flows through 6 counties, China, Myanmar, Laos, Thailand, Cambodia and Viet Nam. The 4 downstream countries have formed the Mekong River Commission to promote sustainable development of the river and many of their people depend on it for their subsistence ? it has possible the largest freshwater fishery in the world, and the Mekong waters support rice agriculture in the delta in Viet Nam (which produces about 40% of that country's food) as well as in Cambodia, Laos and Thailand. China is now building the first large mainstream dam on the river, and has proposals for several more. These dams are likely to affect the downstream countries. Several of the downstream countries also have plans for large scale hydropower and irrigation development which could also impact the river. This book will provide a solid overview of the biophysical environment of the Mekong together with a discussion of the possible impacts, biophysical, economic and social, of some possible development scenarios. It is intended to provide a technical basis which can inform the growing political and conservation debate about the future of the Mekong River, and those who depend on it. It is aimed at river ecologists, geographers, environmentalists and development specialists both in the basin and (especially) outside for whom access to this material is most difficult. This book will be the first comprehensive treatment of the Mekong system. - The first comprehensive overview of all aspects of the Mekong River system - Deals with a regionally critical ecosystem and one under threat - The Mekong supports the world's largest freshwater fishery and provides water underpinning a major regional rice paddy system - Presents the authoritative findings of the Mekong River Commission's research for a wider audience for the first time outside of limited distribution reports

The majority of the examples are taken from regions where the rivers run most of the year.

This book highlights rice and water resources security in Cambodia, Laos, Thailand, and Vietnam – countries that share the international Mekong River, which is a source of both regional cooperation and conflict. It discusses the topography, population, economy, rice production and rice trade of these four riparian countries, and analyses the impacts of climate change, El Nino and La Nina, and the construction of Mekong mainstream dams on water resources and rice productivity. Further, this publication assesses the role of the Mekong River Commission, a river basin organization responsible for the sustainable development and water resource management of the Mekong, and examines regional cooperation frameworks such as the Lower Mekong Initiative, and the Mekong-Japan Summit. The book then explores the emerging role of China in promoting the Lancang-Mekong cooperation between China and Myanmar, Cambodia, Laos, Thailand, and Vietnam in developing the Mekong River Basin, which could determine the future water and rice security of the region.

This book assesses river health in the Lancang River Basin with regard to the impacts of hydropower projects. It studies key components of the transboundary effects of Chinese dams on the Lancang River including its hydrology, sediment transport, water temperature, and fish community. It also investigates the specific impacts of hydropower on women’s lives and livelihoods, and factors that influence women’s participation in river health management. In closing, the lessons learned regarding environmental protection and hydropower development in the Lancang River Basin are shared, e.g. with hydropower developers and regulators in Laos.

The 2020 edition of the WWDR, titled Water and Climate Change illustrates the critical linkages between water and climate change in the context of the broader sustainable development agenda. Supported by examples from across the world, it describes both the challenges and opportunities created by climate change, and provides potential responses – in terms of adaptation, mitigation and improved resilience – that can be undertaken by enhancing water resources management, attenuating water-related risks, and improving access to water supply and sanitation services for all in a sustainable manner. It addresses the interrelations between water, people, environment and economics in a changing climate, demonstrating how climate change can be a positive catalyst for improved water management, governance and financing to achieve a sustainable and prosperous world for all. The report provides a fact-based, water-focused contribution to the knowledge base on climate change. It is complementary to existing scientific assessments and designed to support international political frameworks, with the goals of helping the water community tackle the challenges of climate change, and informing the climate change community about the opportunities that improved water management offers in terms of adaptation and mitigation.
