The impacts of climate change on agriculture and food production in Southeast Asia will be largely mediated through water, but climate is only one driver of change. Water resources in the region will be shaped by a complex mixture of social, economic and environmental factors. This report reviews the current status and trends in water management in the Greater Mekong Subregion; assesses likely impacts of climate change on water resources to 2050; examines water management strategies in the context of climate and other changes; and identifies priority actions for governments and communities to improve resilience of the water sector and safeguard food production.

Climate change has an impact on the ability of transboundary water management institutions to deliver on their respective mandates. The starting point for this book is that actors within transboundary water management institutions develop responses to the climate change debate, as distinct from the physical phenomenon of climate change. Actors respond to this debate broadly in three distinct ways – adapt, resist (as in avoiding the issue) and subvert (as in using the debate to fulfil their own agenda). The book charts approaches which have been taken over the past two decades to promote more effective water management institutions, covering issues of conflict, cooperation, power and law. A new framework for a better understanding of the interaction between transboundary water management institutional resilience and global change is developed through analysis of the way these institutions respond to the climate change debate. This framework is applied to six river case studies from Africa, Asia and the Middle East (Ganges-Brahmaputra, Jordan, Mekong, Niger, Nile, Orange-Senqu) from which learning conclusions and policy recommendations are developed.

This book presents the select proceedings of the Virtual Conference on Disaster Risk Reduction (VCDRR 2021). It emphasizes on the role of civil engineering for a disaster resilient society. It presents latest research on climate change and water security focusing on disaster risk reduction. Various topics covered in this book are climate change, stormwater management, flood risk analysis, drought management, water treatment, etc. This book is a comprehensive volume on disaster risk reduction (DRR) and its management for a sustainable built environment. This book is useful for the students, researchers, policy makers and professionals working in the area of civil engineering, climate change and disaster management.

This study assessed the variability of flows under present and ‘naturalized’ basin conditions in the Upper Ganges Basin (UGB). Furthermore, the PRECIS regional climate model (RCM) was used to generate climate projections for the UGB, with subsequent simulations of future river flows. Results show that the annual average precipitation, actual evapotranspiration (ET) and net water yields of the whole basin were 1,192 mm, 416 mm and 615 mm, respectively. Precipitation, ET and water yields were found to be higher in the forested and mountainous upper areas of the UGB. On an annual average, present-day flows throughout UGB are about 2-8% lower than under naturalized conditions. Dry and wet season flows under climate change (CC) scenario A2 are lower than that under present climate conditions at upstream locations, but higher at downstream locations of UGB. Flows under CC scenario B2 are systematically higher and lower than that under CC scenario A2 during dry and wet seasons, respectively.

The collection of observations and recommendations in this book will prove invaluable to policy makers in countries that are facing similar threats and looking to build their adaptive capacity to cope with climate change. It will also appeal to academi

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.

The Volta River is one of the major rivers in Africa. In this study, a dynamic regional climate model (CCLM), a hydrological model (SWAT) and a water resource model (WEAP) were used to provide an assessment of one downscaled ‘middle impact’ climate change scenario on the performance of existing and planned irrigation and hydropower schemes. The results indicate that, by the middle of the twenty-first century, altered climate is likely to undermine the technical performance of existing and planned reservoirs, which will, in turn, affect development outcomes. Future water resources development in the basin requires interventions that bolster resilience and water security. Much more systematic planning of water storage, greater cooperation between the riparian states and consideration of innovative approaches to water storage are needed.

The environment is one of the defining issues of our times, and it is closely linked to questions and dilemmas surrounding economic development. Southeast Asia is one of the world’s most economically and demographically dynamic regions, and it is also one in which a host of environmental issues raise themselves. The Routledge Handbook of the Environment in Southeast Asia is a collection of 30 chapters dealing with the most significant scholarly debates in this rapidly growing field of study. Structured in four main parts, it gives a comprehensive regional overview of, and insight into, the environment in Southeast Asia. Wide-ranging and balanced, this handbook promotes scholarly understanding of how environmental issues are dealt with from diverse theoretical perspectives. It offers a detailed empirical understanding of the myriad environmental problems and challenges faced in Southeast Asia. This is the first publication of its kind in this field; a helpful companion for a global audience and for scholars of Southeast Asian studies from a variety of disciplines.
