Climate And Food Security

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 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.

Global climatic change has resulted in new and unpredictable patterns of precipitation and temperature, the increased frequency of extreme weather events and rising sea levels. These changes impact all four aspects of food security – availability, accessibility, stability of supply and appropriate nourishment – as well as the entire food system – food production, marketing, processing, distribution and prices. Climate Change and Food Security focuses on the challenge to food security posed by a changing climate. The book brings together many of the critical global concerns of climate change and food security through local cases based on empirical studies undertaken in Sub-Saharan Africa and the Caribbean. Focusing on risk reduction and the complex nature of vulnerability to climate change, the book includes chapters on the responsiveness of farmers based on traditional knowledge, as well as the critical phenomenon of food insecurity in the urban setting. Other chapters are devoted to efforts made to strengthen resilience through long-term development, with interventions at the regional and national levels of scale. It also examines cross-cutting themes that underlie the strategies employed to achieve food security, including equity, gender, livelihoods and governance. This edited volume will be of great interest to students and scholars of climate change, food security, environmental management and sustainable development.

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.

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

With the potential to impact weather patterns, agriculture, and habitability of certain regions, global warming is a topic of interest to environmentalists, scientists, as well as farmers around the world. The threat of food shortages and famine especially becomes a major concern as a result of recent climate shifts. Impacts of Climate Change on Food Security in Small Island Developing States discusses the repercussions of a shifting climate on food production and availability in small island nations. Comprised of research-based chapters on topics relevant to crop management, sustainable development, and livestock management on island territories, this advanced reference work is appropriate for environmental researchers, food scientists, academicians, and upper-level students seeking the latest information on agricultural concerns amidst a changing climate.

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.

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.
