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.

Nature-based solutions (NBS) are interventions to protect, restore, and sustainably manage natural or modified ecosystems to support both biodiversity and human well-being. This guide explores the benefits of using NBS in a suite of development options to promote sustainable and resource-efficient infrastructure. It includes case studies from Bangladesh, Nepal, the People's Republic of China, the Philippines, and Viet Nam to show how NBS can be mainstreamed in the portfolio of the Asian Development Bank.

New evidence this year corroborates the rise in world hunger observed in this report last year, sending a warning that more action is needed if we aspire to end world hunger and malnutrition in all its forms by 2030. Updated estimates show the number of people who suffer from hunger has been growing over the past three years, returning to prevailing levels from almost a decade ago. Although progress continues to be made in reducing child stunting, over 22 percent of children under five years of age are still affected. Other forms of malnutrition are also growing: adult obesity continues to increase in countries irrespective of their income levels, and many countries are coping with multiple forms of malnutrition at the same time – overweight and obesity, as well as anaemia in women, and child stunting and wasting.

Climate Change and Cities bridges science-to-action for climate change adaptation and mitigation efforts in cities around the world.

'Economic losses from natural disasters totaled $92 billion in 2015.' Such statements, all too commonplace, assess the severity of disasters by no other measure than the damage inflicted on buildings, infrastructure, and agricultural production. But $1 in losses does not mean the same thing to a rich person that it does to a poor person; the gravity of a $92 billion loss depends on who experiences it. By focusing on aggregate losses—the traditional approach to disaster risk—we restrict our consideration to how disasters affect those wealthy enough to have assets to lose in the first place, and largely ignore the plight of poor people. This report moves beyond asset and production losses and shifts its attention to how natural disasters affect people’s well-being. Disasters are far greater threats to well-being than traditional estimates suggest. This approach provides a more nuanced view of natural disasters than usual reporting, and a perspective that takes fuller account of poor people’s vulnerabilities. Poor people suffer only a fraction of economic losses caused by disasters, but they bear the brunt of their consequences. Understanding the disproportionate vulnerability of poor people also makes the case for setting new intervention priorities to lessen the impact of natural disasters on the world’s poor, such as expanding financial inclusion, disaster risk and health insurance, social protection and adaptive safety nets, contingent finance and reserve funds, and universal access to early warning systems. Efforts to reduce disaster risk and poverty go hand in hand. Because disasters impoverish so many, disaster risk management is inseparable from poverty reduction policy, and vice versa. As climate change magnifies natural hazards, and because protection infrastructure alone cannot eliminate risk, a more resilient population has never been more critical to breaking the cycle of disaster-induced poverty.

"This atlas provides the first truly global assessment of the state of the world's mangroves. Written by the leading expert on mangroves with support from the top international researchers and conservation organizations, this full color atlas contains 60 full-page maps, hundreds of photographs and illustrations and a comprehensive country-by-country assessment of mangroves. Included are the first detailed estimates of changes in mangrove forestcover worldwide and at regional and national levels, an assessment of these changes and a country-by-country examination of biodiversity protection. The book also presents a wealth of global statistics on biodiversity, habitat area, loss and economic value which provide a unique record of mangroves against which future threats and changes can be evaluated. Case-studies, written by regional experts, provide insights into regional mangrove issues, including primary and potential productivity, biodiversity, and information on present and traditional uses and values and sustainable management."--Pub. desc.

On top of a decade of exacerbated disaster loss, exceptional global heat, retreating ice and rising sea levels, humanity and our food security face a range of new and unprecedented hazards, such as megafires, extreme weather events, desert locust swarms of magnitudes previously unseen, and the COVID-19 pandemic. Agriculture underpins the livelihoods of over 2.5 billion people – most of them in low-income developing countries – and remains a key driver of development. At no other point in history has agriculture been faced with such an array of familiar and unfamiliar risks, interacting in a hyperconnected world and a precipitously changing landscape. And agriculture continues to absorb a disproportionate share of the damage and loss wrought by disasters. Their growing frequency and intensity, along with the systemic nature of risk, are upending people’s lives, devastating livelihoods, and jeopardizing our entire food system. This report makes a powerful case for investing in resilience and disaster risk reduction – especially data gathering and analysis for evidence informed action – to ensure agriculture’s crucial role in achieving the future we want.

This open access book is based on the research outputs of China Council for International Cooperation on Environment and Development (CCICED) in 2020. It covers major topics of Chinese and international attention regarding green development, such as climate, biodiversity, ocean, BRI, urbanization, sustainable production and consumption, technology, finance, value chain, and so on. It also looks at the progress of China's environmental and development policies,and the impacts from CCICED. This is a highly informative and carefully presented book, providing insight for policy makers in environmental issues.

Over recent years, nature-based solutions (NbS) have gained popularity as tools to ameliorate the effects of climate change, while slowing down the global warming process. More specifically, the potential of NbS has been explored in terms of meeting greenhouse gas emissions targets, and fostering climate change adaptation. NbS are methods that use and enhance nature to improve social and environmental challenges. They involve several multifaceted actions, that work sustainably to restore and protect the natural environment while helping people. Therefore, these solutions are useful in climate change adaptation and mitigation. There are 3 main areas which NbS may target, namely reducing exposure, reducing sensitivity, and supporting adaptive capacity. Reducing exposure refers to protecting areas from existing climate change effects. There is thus a perceived need to document and promote experiences related to NbS, and to apply these in different contexts. It is against this background that the "Handbook of Nature-Based Solutions to Mitigation and Adaptation to Climate Change" is being produced. The publication will showcase experiences related to NbS from around the world. In particular, it will gather examples of projects, studies and the latest thinking on NbS, which can serve the purpose of inspiring and fostering further works in this key area. Thanks to its scope and thematic diversity, the book will be of special interest to representatives from government organisations, researchers and students from a wide range of natural and social sciences courses. It will also provide useful information to practitioners and representatives from non-governmental organisations.
