Climate Change and Food Security


Book Description

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.




Food Security and Climate Change


Book Description

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.




Climate Change and Food Security in South Asia


Book Description

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.




Climate Change and Food Security with Emphasis on Wheat


Book Description

Climate Change and Food Security with Emphasis on Wheat is the first book to present the full scope of research in wheat improvement, revealing the correlations to global issues including climate change and global warming which contribute to food security issues. Wheat plays a key role in the health of the global economy. As the world population continuously increases, economies modernize, and incomes rise, wheat production will have to increase dramatically to secure it as a reliable and sustainable food source. Since covering more land area with wheat crops is not a sustainable option, future wheat crops must have consistently higher yields and be able to resist and/or tolerate biotic and abiotic stresses that result from climate change. Addressing the biophysical and socioeconomic constraints of producing high-yielding, disease-resistant, and good quality wheat, this book will aid in research efforts to increase and stabilize wheat production worldwide. Written by an international team of experts, Climate Change and Food Security with Emphasis on Wheat is an excellent resource for academics, researchers, and students interested in wheat and grain research, especially as it is relevant to food security. - Covers a wide range of disciplines, including plant breeding, genetics, agronomy, physiology, pathology, quantitative genetics and genomics, biotechnology and gene editing - Explores the effect of climate change on biotic stresses (stripe rust, stem rust, leaf rust, Karnal bunt, spot blotch) on wheat production and utilization of biotechnology - Focuses on whole genome sequencing and next-generation sequencing technologies to improve wheat quality and address the issue of malnutrition in developing world

Climate Change and Food Security in West Asia and North Africa


Book Description

The countries of West Asia and North Africa (WANA) have long had the challenge of providing sustainable livelihoods for their populations in the fragile ecosystems of semi-arid and arid areas. Climate change is already a reality in WANA and it places additional constraints on the already fragile ecosystems of dry areas and limited natural resources in WANA. A comprehensive and integrated approach to planning and implementing the climate change adaptation strategies across the wide range of agro-ecosystems in different countries in WANA could help both the planners and the local communities to deal effectively with the projected impacts and also contribute to overall sustainability of agricultural production systems. This book addresses the important issue of climate change and food security in West Asia and North Africa and presents the appropriate strategies which could help in the development of new policies to better adapt agriculture production systems and enhance food security in WANA.




Climate Change and Global Food Security


Book Description

In order to feed their burgeoning populations, developing nations will need to double cereal production by the year 2050. This increase will have to come from existing land, as little potential exists for bringing new land under cultivation -- a daunting prospect when one realizes that increased use and significantly higher concentrations of carbon




Climate Change Risks and Food Security in Bangladesh


Book Description

Managing climate variability and change remains a key development and food security issue in Bangladesh. Despite significant investments, floods, droughts, and cyclones during the last two decades continue to cause extensive economic damage and impair livelihoods. Climate change will pose additional risks to ongoing efforts to reduce poverty. This book examines the implications of climate change on food security in Bangladesh and identifies adaptation measures in the agriculture sector using a comprehensive integrated framework. First, the most recent science available is used to characterize current climate and hydrology and its potential changes. Second, country-specific survey and biophysical data is used to derive more realistic and accurate agricultural impact functions and simulations. A range of climate risks (i.e. warmer temperatures, higher carbon dioxide concentrations, changing characteristics of floods, droughts and potential sea level rise) is considered to gain a more complete picture of potential agriculture impacts. Third, while estimating changes in production is important, economic responses may to some degree buffer against the physical losses predicted, and an assessment is made of these. Food security is dependent not only on production, but also future food requirements, income levels and commodity prices. Finally, adaptation possibilities are identified for the sector. This book is the first to combine these multiple disciplines and analytical procedures to comprehensively address these impacts. The framework will serve as a useful guide to design policy intervention strategies and investments in adaptation measures.




Climate Resilient Agriculture for Ensuring Food Security


Book Description

Climate Resilient Agriculture for Ensuring Food Security comprehensively deals with important aspects of climate resilient agriculture for food security using adaptation and mitigation measures. Climatic changes and increasing climatic variability are likely to aggravate the problem of future food security by exerting pressure on agriculture. For the past few decades, the gaseous composition of the earth’s atmosphere has been undergoing significant changes, largely through increased emissions from the energy, industry and agriculture sectors; widespread deforestation as well as fast changes in land use and land management practices. Agriculture and food systems must improve and ensure food security, and to do so they need to adapt to climate change and natural resource pressures, and contribute to mitigating climate change. Climate-resilient agriculture contributes to sustainably increasing agricultural productivity and incomes, adapting and building resilience to climate change and reducing and/or eliminating greenhouse gas emissions where possible. The information on climate resilient agriculture for ensuring food security is widely scattered. There is currently no other book that comprehensively and exclusively deals with the above aspects of agriculture and focuses on ensuring food security. This volume is divided into fourteen chapters, which include the Introduction, Causes of Climate Change, Agriculture as a Source of Greenhouse Gases, Impacts of Climate Change on Agriculture, Regional Impacts on Climate Change, Impacts on Crop Protection, Impacts on Insect and Mite Pests, Impacts on Plant Pathogens, Impacts on Nematode Pests, Impacts on Weeds, Impacts on Integrated Pest Management, Climate Change Adaptation, Climate Change Mitigation, and A Road Map Ahead. The book is extensively illustrated with excellent photographs, which enhance the quality of publication. It is clearly written, using easy-to-understand language. It also provides adoptable recommendations involving eco-friendly adaptation and mitigation measures. This book will be of immense value to the scientific community involved in teaching, research and extension activities. The material can also be used for teaching post-graduate courses. It will also serve as a very useful reference source for policy makers.




Food security and nutrition in the age of climate change


Book Description

After steadily declining for over a decade, global hunger is on the rise again, while various forms of malnutrition coexist. Climate change is already exacerbating this grim picture, which is why food security and food production will be a major focus of the Intergovernmental Panel on Climate Change’s 6th Assessment Cycle. Thanks to the participation of 250 experts from all around the world, the International Symposium on Food Security and Nutrition in the Age of Climate Change highlighted the importance of food and agricultural systems in the fight against climate change and presented concrete multi-sector solutions to address this global issue. The event placed special emphasis on the regional realities of West Africa and the Canadian North, as well as to the presence of young people and members of Indigenous and Northern communities directly affected by these issues. The summaries of these four days of plenaries, interactive workshops, and special events have been grouped under seven major themes for this publication: 1) Climate change, food security and nutrition: the issues; (2) The agriculture sectors in the context of climate change; (3) Food systems in the face of climate change; (4) Natural resources: challenges and solutions; (5) Food security and nutrition in a changing North; (6) Summary of solutions; (7) Strengthening and adapting regional and international cooperation.
