A Study On Impacts Of Climate Change Of Water Resources In The Lower Mekong Basin

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.

This book brings together a talented international group of scholars, policy practitioners, and NGO professionals that explores a range of issues relating to environmental, developmental, and governing challenges on the Mekong, one of the world’s greatest rivers and, alas, one of the most endangered. The book is divided into three sections devoted in turn to historical perspectives on the Lower Mekong Basin. Issues relate to livelihood strategies, environmental threats, and adaptation strategies; and various aspects of river governance, with individual authors treating questions of governance at different levels of refraction and in different registers. The result is a fresh and innovative collection of essays, which, taken together, provide much-needed new perspectives on some of the most important and seemingly intractable environmental and development issues in contemporary Asia.

The Mekong River Basin: Ecohydrological Complexity from Catchment to Coast, Volume Three presents real facts, data and predictions for quantifying human-induced changes throughout the Mekong watershed, including its estuaries and coasts, and proposes solutions to decrease or mitigate the negative effect and enable sustainable development. This is the first work to link socio–ecological interaction study over the whole Mekong River basin through the lens of ecohydrology. Each chapter is written by a leading expert, with coverage on climate change, groundwater, land use, flooding drought, biodiversity and anthropological issues. Human activities are enormous in the whole watershed and are still increasing throughout the catchment, with severe negative impacts on natural resources are emerging. Among these activities, hydropower dams, especially a series of 11 dams in China, are the most critical as they generate massive changes throughout the system, including in the delta and to the livelihoods of millions of people and they threaten sustainability. Presents an extensive collection of eco-hydrological changes in the river basin driven by both nature and anthropological factors Provides state of the art modeling, data analysis methodologies for complex socio-ecological complexity applied in the Mekong river basin Includes specific cases of ecohydrology in the river basin, especially from the Mekong delta

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

This book about the Mekong Delta presents a unique collection of state-of-the-art contributions by international experts from different scientific disciplines about the characteristics and pressing water-related challenges of the Mekong Delta in Vietnam. The Mekong Delta belongs to one of the areas, which are to expect the largest challenges concerning environmental change and climate change induced sea level rise . The Delta acts as the “rice bowl” of Southeast Asia and is home to over 17 Million people, who need to cope with ecologic as well as socio-economic changes linked to the rapid economic development of the country. Annual floods, severe droughts, salt water intrusion, degrading water quality, tropical cyclones, hydrologic changes due to hydropower projects in the upstream of the Mekong, coastal erosion, and the loss of biodiversity are some of the problems in the region. Heterogeneous resource management responsibilities, and the fact that the Mekong – and thus also the Delta – is influenced by six countries aggravate the situation. Integrated water resources management and fostered cooperation and information exchange are pressing needs for the sustainable development of the Delta.

In Asia and the Pacific, climate change is now a well-recognised risk to water security but responses to this risk are either under reported, or continue to be guided by the incremental or business as usual approaches. Water policy still tends to remain too narrow and fragmented, compared to the multi-sectoral and cross-scalar nature of risks to water security. What’s more, current water security debates tend to be framed in discipline specific or academic ways, failing to understand decision making and problem-solving contexts within which policy actors and partitioners have to operate on a daily basis. Much of the efforts to date has focussed on assessing and predicting the risks in the context of increasing levels of uncertainty. There is still limited analysis of emerging practices of risks assessment and mitigation in different contexts in Asia and the Pacific. Going beyond the national scales and focussing on several socio-ecological zones, this book captures stories written by engaged scholars on recent attempts to develop cross-sectoral and cross-scaler solutions to assess and mitigate risks to water security across Asia and the Pacific. Identifying lessons from successes and failures, it highlights management and strategic lessons that water and climate leaders of Asia and the Pacific need to consider. This book showcases reflective and analytical thought pieces written by key actors in the climate and water spaces. Several critical socio-ecological zones are covered – from Pakistan in the west to pacific islands in the east. The chapters clearly identify strategies for improvement based on the analysis of emerging responses to climate risks to water security and gaps in current practices. The book will include an editorial introduction and a final synthesis chapter to ensure clear articulation of common themes and to highlight the overall messages of the book.
