This book addresses an important topic of food security in South Asia with specific reference to climate change. Of the 1 billion food insecure people in the world, more than 30% are in South Asia. The problem of food insecurity may be exacerbated by the projected climate change especially because of the water scarcity caused by rapid melting of the glaciers in the Himalayas and increase in variability in monsoonal rains and frequency of extreme events. Furthermore, large populations of Bangladesh and other coastal regions may be displaced by sea level rise. Thus, this volume addresses recommended land use and soil/water/crop/vegetation management practices which would enable land managers to adapt to climate disruption by enhancing soil/ecosystem/social resilience. In addition to biophysical factors, this book also addresses the issues related to human dimensions including social, ethnical and political considerations.
This volume foregrounds the importance of regional cooperation in the context of food security challenges in South Asia. South Asia holds the key to global achievement of SDG targets of ending hunger and malnutrition – it accounts for nearly one-third of food-insecure people on the planet, with every third child suffering from stunting due to malnutrition. Similar food preferences, production systems, and the transboundary nature of agrarian ecosystems call for coordinated action by South Asian countries, complementing national actions dealing with food security challenges. In this volume, leading experts discuss the perspectives of key South Asian countries in leveraging regional cooperation for addressing food security challenges and reflect on the potential of cooperative actions in different areas. The book proposes a ten-point regional policy agenda covering cooperation for combatting climate change, regional trade liberalization, operationalization of regional food reserves, leveraging technology, sharing of good practices, regional institution building, coordinated positions in multilateral trade negotiations, addressing trans-boundary outbreak of livestock diseases, strengthening food safety standards, and the management of shared natural resources. A key volume on accomplishing SDGs in the South Asian context, this book will be of immense interest to policy makers, researchers, and development practitioners. It is also essential reading for scholars and researchers in the areas of development studies, South Asia studies, food security, environment and sustainability.
Using an interdisciplinary approach, this book evaluates the complex nexus between climate change and regional food security in Asia Pacific. Feeding the planet puts a lot of stress on the environment. The fundamental challenges we are facing today include how to grow more from less in a sustainable manner; how to optimize the entire food value chain from field to fork to reduce the carbon footprint, protect the environment and support biological diversity, cause less water pollution and soil erosion, raise levels of nutrition, improve agricultural productivity, better the lives of rural populations and contribute to the growth of the world economy. With a robust multi-site study in Southeast Asia, Pacific Island Forum and South Asia, this book examines the regional initiatives on, the current state of, and the future prospects for mitigations and resilience regarding climate change and food security vis-à-vis other regions of the world.
This book looks at the current state of food security and climate change, discusses the issues that are affecting them, and the actions required to ensure there will be enough food for the future. By casting a much wider net than most previously published books—to include select novel approaches, techniques, genes from crop diverse genetic resources or relatives—it shows how agriculture may still be able to triumph over the very real threat of climate change. Food Security and Climate Change integrates various challenges posed by changing climate, increasing population, sustainability in crop productivity, demand for food grains to sustain food security, and the anticipated future need for nutritious quality foods. It looks at individual factors resulting from climate change, including rising carbon emission levels, increasing temperature, disruptions in rainfall patterns, drought, and their combined impact on planting environments, crop adaptation, production, and management. The role of plant genetic resources, breeding technologies of crops, biotechnologies, and integrated farm management and agronomic good practices are included, and demonstrate the significance of food grain production in achieving food security during climate change. Food Security and Climate Change is an excellent book for researchers, scientists, students, and policy makers involved in agricultural science and technology, as well as those concerned with the effects of climate change on our environment and the food industry.
Roughly a billion people around the world continue to live in state of chronic hunger and food insecurity. Unfortunately, efforts to improve their livelihoods must now unfold in the context of a rapidly changing climate, in which warming temperatures and changing rainfall regimes could threaten the basic productivity of the agricultural systems on which most of the world’s poor directly depend. But whether climate change represents a minor impediment or an existential threat to development is an area of substantial controversy, with different conclusions wrought from different methodologies and based on different data. This book aims to resolve some of the controversy by exploring and comparing the different methodologies and data that scientists use to understand climate’s effects on food security. In explains the nature of the climate threat, the ways in which crops and farmers might respond, and the potential role for public and private investment to help agriculture adapt to a warmer world. This broader understanding should prove useful to both scientists charged with quantifying climate threats, and policy-makers responsible for crucial decisions about how to respond. The book is especially suitable as a companion to an interdisciplinary undergraduate or graduate level class.
This synthesis report is the result of close, collaborative research initiated by the Asian Development Bank in partnership with Foreign Affairs, Trade and Development Canada; the Asia-Pacific Economic Cooperation; and the Liu Institute for Global Issues at the University of British Columbia. Fourteen background papers were commissioned to investigate food security issues particularly pertinent for Asia and the Pacific. The report synthesizes and collates the primary findings from these papers to articulate key policy challenges and opportunities related to food security in the region.
This report focuses on the risks of climate change to development in Sub-Saharan Africa, South East Asia and South Asia. Building on the 2012 report, Turn Down the Heat: Why a 4°C Warmer World Must be Avoided, this new scientific analysis examines the likely impacts of present day, 2°C and 4°C warming on agricultural production, water resources, and coastal vulnerability. It finds many significant climate and development impacts are already being felt in some regions, and that as warming increases from present day (0.8°C) to 2°C and 4°C, multiple threats of increasing extreme heat waves, sea-level rise, more severe storms, droughts and floods are expected to have further severe negative implications for the poorest and most vulnerable. The report finds that agricultural yields will be affected across the three regions, with repercussions for food security, economic growth, and poverty reduction. In addition, urban areas have been identified as new clusters of vulnerability with urban dwellers, particularly the urban poor, facing significant vulnerability to climate change. In Sub-Saharan Africa, under 3°C global warming, savannas are projected to decrease from their current levels to approximately one-seventh of total land area and threaten pastoral livelihoods. Under 4°C warming, total hyper-arid and arid areas are projected to expand by 10 percent. In South East Asia, under 2°C warming, heat extremes that are virtually absent today would cover nearly 60-70 percent of total land area in northern-hemisphere summer, adversely impacting ecosystems. Under 4°C warming, rural populations would face mounting pressures from sea-level rise, increased tropical cyclone intensity, storm surges, saltwater intrusions, and loss of marine ecosystem services. In South Asia, the potential sudden onset of disturbances to the monsoon system and rising peak temperatures would put water and food resources at severe risk. Well before 2°C warming occurs, substantial reductions in the frequency of low snow years is projected to cause substantial reductions in dry season flow, threatening agriculture. Many of the worst climate impacts could still be avoided by holding warming below 2°C, but the window for action is closing rapidly. Urgent action is also needed to build resilience to a rapidly warming world that will pose significant risks to agriculture, water resources, coastal infrastructure, and human health.
South Asia is particularly vulnerable to climate change. Most previous studies have focused on the projected impacts of sea-level rise or extreme weather - droughts, floods, heatwaves and storm surges. This study adds to that knowledge by identifying the impacts of long-term changes in the climate †“ rising temperatures and changes in precipitation patterns †“ on living standards. It does so by first building an understanding of the relationship between current climate conditions and living standards across South Asia. The study also identifies the set of climate models that are best suited for projecting long-term changes in climate across South Asia. This novel understanding of living standards and climate change is then combined to project impacts of long-term changes in climate on living standards in South Asia. The study finds that higher temperatures will reduce living standards for most of South Asia, with the severity impacts depending on future global greenhouse gas emissions. The study projects “hotspots†?, which are locations where long-term changes in climate will have negative impacts on living standards. Many hotspots are in locations that hitherto have not been identified as particularly vulnerable to climate change. Moreover, hotspots have distinguishing features that vary from country to country. This detailed assessment provides a mosaic of information that enriches our understanding of how climate change will impact people and which populations are most vulnerable. The report also provides guidance on the kinds of actions are most likely to reduce impacts of climate change in each country. The study is a major contribution to our understanding of how increasing temperatures and changing precipitation patterns interact with social and economic structures at a fine granular level across South Asia.
Dialogue on global warming has progressed from the Kyoto Protocol to meetings in Copenhagen and Cancun and will soon resume in meetings in South Africa. Some observers consider the Copenhagen conference a failure. EU representatives, in contrast, present an optimistic evaluation of achieving a global temperature rise limit of not more than 2°C by 2100. Geoscience researchers and lead investigators of the Intergovernmental Panel on Climate Change (IPCC) have supported CO2 emission reduction pledges and contend that we can achieve the 2°C limit through international coordination. This position conflicts with evaluations of United States Congressional and Presidential advisors, who do not believe the Copenhagen CO2 reduction commitments can hold the global warming increase to below 2°C and who have not supported the agreement. Developing countries are alarmed, because climate change is expected to hit them hardest. The developed world will use energy to mitigate global warming effects, but developing countries are more exposed by geography and poverty to the most dangerous consequences of a global temperature rise. The Oxford Handbook of the Macroeconomics of Global Warming analyzes the macroeconomics of global warming, especially the economics of possible preventative measures, various policy changes, and potential effects of climate change on developing and developed nations.
