This book proposes the use of green infrastructure to balance biodiversity conservation and disaster management. Paddy fields are one example of such infrastructure and are the focus of this book. In Japan, abandoned, once-cultivated land is increasing in the paddy fields due to the aging of society and recent depopulation. The author proposes to consolidate such lands and create wetlands because the paddy fields hold water during heavy rains, which prevents floods and protects cities. This is essential, considering that extreme weather conditions have increased the risk of flood damage in Japan. Not only do such wetlands hold water during the flood season, they also provide habitats for aquatic life and places for children to learn about the natural environment. In addition, fish farming in the wetlands will provide food for many people. The increase in water disasters associated with global warming is occurring not only in Japan but globally. The proposal presented in this book will help government officials around the world, especially those involved in urban and rural planning, to consider disaster management—an idea that will be welcomed by both engineers and biologists.

Under FAO initiative on eco-friendly water management for sustainable wetland agriculture, the Asian Institute of Technology (AIT), as the service provider, prepared the Study Report on Wetland Agriculture and Water Management in Mekong Region study report on wetland agriculture and water management in the Mekong Region for further program formulation. The overall objective is to review the current water management in relation to agriculture and identify the good practices and experiences of water management as a win-win solution for agriculture production and wetland conservation and recommend program formulation on eco-friendly water management for sustainable wetland agriculture. The expected outcome of the overall initiative is sustainable use of wetland to stress both productive and ecological functions of agriculture. The outputs aim to provide the solution as a win-win strategy for wetland and agriculture through eco-friendly water management, which will contribute to the ecological health, function and integrity of the Mekong Wetland Agriculture Ecosystem. Country consultation workshops were conducted for Cambodia, Laos, Thailand, and Vietnam to increase awareness on the issues of sustainable wetland management, and identify the threats, gaps and needs, priorities, and way forward towards sustainable use of wetlands in the Mekong Region.

This open access book introduces the function, implementation and governance of green infrastructure in Japan and other countries where lands are geologically fragile and climatologically susceptible to climate change. It proposes green infrastructure as an adaptation strategy for climate change and biodiversity conservation. In the face of climate change, dams, levees and floodways built as disaster prevention facilities do not sufficiently function against extraordinary events such as mega-floods and tsunami disasters. To prevent those disasters and loss of biodiversity in various ecosystems, we should shift from conventional hard measures to more adaptive strategies using various functions that natural and semi-natural ecosystems provide. Green infrastructure is an interconnected network of waterways, wetlands, woodlands, wildlife habitats and other natural areas that support native species, maintain natural ecological processes, sustain air and water resources and contribute to the health and quality of life for communities and people. Green infrastructure has mainly been discussed from adaptation strategy perspectives in cities and urban areas. However, to protect cities, which are generally situated at downstream lower elevations, we explore the preservation and restoration of forests at headwater basins and wetlands along rivers from a catchment perspective. In addition, the quantitative examination of flood risk, biodiversity, and social-economic benefits described in this book brings new perspectives to the discussion. The aim of this book is to accelerate the transformative changes from gray-based adaptation strategies to green- or hybrid-based strategies to adapt to climate change. The book provides essential information on the structure, function, and maintenance of green infrastructure for scientists, university students, government officers, and practitioners.

The three case studies address different issues in different countries. All case studies attempt to provide incentives and trade-off mechanisms that are mutually beneficial for both agricultural production and the environment. Thailand organic rice cultivation and Viet Nam flood-based cropping systems are the examples on market mechanisms; while China case and Thailand floods control are government/policy driven. All case studies draw on extensive desk reviews and field studies.

This book provides an introduction to the critical role of ecosystem-based disaster risk resilience (Eco-DRR) for building community resilience to multiple environmental risks such as rising heat, water stress, and pollution. Blue-green infrastructure (BGI) is an Eco-DRR tool that is an under-explored paradigm and can respond as one common strategy to targets set by the Sustainable Development Goals (UNDP), Climate Agreements (UNEP), the Sendai Framework (UNISDR), and the New Urban Agenda (UNCHS). Highlighted here in a systematic way is the importance of blue-green infrastructures in resilience building. The purpose is to introduce readers to the challenging context of development and opportunity creation for Eco-DRR. The roles of policy, scientific research, and implementation are presented cohesively. An attractive proposition of the book is a collection of case studies from different parts of the world where integration of BGI is experimented with at various levels of success. It envisages that shared tacit experiences from the realm of practice will further strengthen explicit knowledge. The focus in this book is on need and context building, policy and science (investigation, analysis, and design), case studies, and a road map for the future in four successive parts. Each part is self-sufficient yet linked to its predecessor, successor, or both, as the case may be.
