Climate Change Risk And Adaptation Assessment For Irrigation In Southern Viet Nam

This publication presents findings from a climate change risk and adaptation assessment in southern Viet Nam as part of the Water Efficiency Improvement in Drought-Affected Provinces (WEIDAP) project supported by the Asian Development Bank. It highlights new developments and key lessons on climate risk assessment that may be applied to the project design and monitoring as well as the implementation of climate adaptation measures. The WEIDAP project was developed in response to the drought that affected southern Viet Nam in 2015–2016. It focused on irrigation modernization and the integration of climate-resilient agricultural and efficient on-farm water management practices.

This book describes the iterative steps that were successfully undertaken to develop adaptation measures to climate change in two Vietnamese provinces. The methodology used to develop the scientific basis and the societal agreement of the need to adapt to climate change is applicable also to other regions in Vietnam, Asia and worldwide. The uncertainties of climate change models make it difficult to justify investments to finance protection from uncertain impacts. Setting out with the projected climate change impacts in Vietnam, which is one of the most vulnerable countries to climate change, the book describes a methodological approach to assess and evaluate local vulnerabilities of natural resources to climate change and socio-economic impacts, engaging local stakeholders in the development of locally acceptable and economically feasible adaptation measures. The methodological approach to understand the vulnerabilities and to develop climate change adaptation measures was scenario workshops that supported the communication between scientists and stakeholders. The development of climate change adaptation strategies is nearly state-of-the-art in many countries, but often there is still a large step towards implementing climate change adaptation measures on the local level. The challenge in the development of adaptation measures lies in their acceptability by local stakeholders and decision makers. Climate change adaptation measures also usually demand investments. To understand potential future risks the communication methodology was to first get a good understanding of the natural resources (mainly surface and groundwater) and their potential vulnerabilities (current and future). This was followed by developing a common understanding of current risk patterns, as well as underlying vulnerabilities and hazards. Socio-economic developments have an equally strong, and in the short term mostly even stronger, impact on the living environment and natural resources as long-term climate change impacts. The scenario workshops developed a holistic approach on current and potential future risk patterns, with a special focus on surface and groundwater quantities and qualities, natural hazards and sea level rise. Land-use planning was identified as playing a decisive role in minimizing current and future risks. Finally, first adaptation measures for two Vietnamese provinces were developed and shall be implemented over the next years. The methodology that led to these adaptation measures shall be applied in other Vietnamese provinces.

This book is intended to fill a gap in climate-change literature by providing a comprehensive regional study and identifying the overall adaptation challenges in a real-life context. The way in which possible climate impacts interact with a range of other challenges in agriculture, forestry, disaster planning, health care, general economic development, and common livelihoods are presented, and it is argued that greater realism and broader vision are needed in order to address the climate challenge. For instance, unsuitable land- use changes in both coastal and highland regions may increase the vulnerability of rural people, many of whom are already living on the fringes. The author(s) also state(s) that, depending on context, it may be pertinent to address short-term and unsustainable resource use, irregularities in local land management, ineffective governance and social inequality, which are all likely to aggravate the impact of external climate and weather. Not least, it is imperative to integrate general environmental management with any climate-change adaptation effort.

Coastal Disasters and Climate Change in Vietnam is the first book to focus specifically on natural hazards and climate change in Vietnam. The book examines threats such as tropical cyclones, sea-level rise, flooding, erosion, and salinity intrusion, and their respective effects on coastal structures and environments. It also looks at crucial management and mitigation efforts, including breakwater design, irrigation systems, coastal dunes and dikes, and more. The challenges faced by this country in the future will have important regional and global repercussions; areas such as the Mekong Delta produce a significant proportion of the world’s rice, and coastal impacts on this region will have far-reaching economic and public health effects. This book is an important source of information for government and local policy makers, environmental and climate scientists, and engineers. Broad coverage of climate challenges specific to the region, including sea-level rise, storms, erosion, and more Assessments of impact on, and effects of, economic development and port construction Examination of public policy responses to climate change

This book analyzes climate change associated effects in the mountainous and coastal environments of Vietnam. The scope of the book allows international comparisons to be made between these two affected areas and other similarly affected locations under constant environmental pressure. Frequent and intense climate change hazards are described, along with a wider context of integrated interpretations, socioeconomic implications and policy responses. The book reports on original research combining methodologies from the natural sciences with approaches in human sciences, providing an interdisciplinary human ecological context to analyze similar situations worldwide. The book is structured in four parts. The first part offers background information, and details the human ecological framework. The geography of the analyzed regions is discussed to reflect the environmental and socioeconomic context of Vietnam's coasts and mountains. The second part addresses the coast of Central Vietnam. The effects of tropical storms, floods, rising sea levels and coastal erosion in Ky Anh are studied to highlight the impacts on the local population and its development perspectives. The third part focuses on the uplands of Northern Vietnam. The effects of cyclones, heavy rains, floods, flash floods, and landslides in the Van Chan Mountains are studied to compare the biophysical and socioeconomic impacts. Part four makes policy recommendations in building resilient landscapes and green cities, and discusses the potential implications of findings for practice in Vietnam. The book addresses a wide array of researchers, geography and economics students, consultants and decision makers interested in the actual status and the likely developments on the physical, socioeconomic and mitigation and adaptation attitudes and policies of climate change associated effects.

Vietnam and the neighbouring countries of Southeast Asia face diverse challenges created by the rapid evolution of their social, economic and environmental systems and resources. Taking a multidisciplinary perspective, this book provides a comprehensive assessment of the Vietnamese situation, identifying the factors shaping social vulnerability and resilience to environmental change and considering prospects for sustainable development.

This knowledge product explains the rationale and procedures for incorporating allowances for climate change in detailed engineering design, with a focus on credible adjustments to extreme rainfall and to mean and high-end sea-level rise. Highlighting worked examples drawn from Viet Nam's road transport sector and peer-reviewed research literature, it offers a point of departure for more sophisticated assessments of high-risk projects. It presents principles and approaches extendable to other design variables (extreme air temperature, evaporation, and wind speed) and transferable to other sectors, regions, and stages of the asset life cycle (from project concept to decommissioning). An accompanying step-by-step manual shows how each calculation is performed.
