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

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.

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.

Book Description :

This volume discusses a broad range of vital issues encompassing the production and consumption of food in the current period of climate change. All of these add up to looming, momentous challenges to food security, especially for people in regions where malnutrition and famine have been the norm during numerous decades. Furthermore, threats to food security do not stop at the borders of more affluent countries – governance of food systems and changes in eating patterns will have worldwide consequences. The book is arranged in four broad sections. Part I, Combating Food Insecurity: A Global Responsibility opens with a chapter describing the urgent necessity for new paradigm and policy set to meet the food security challenges of climate change. Also in this section are chapters on meat and the dimensions of animal welfare, climate change and sustainability; on dietary options for mitigating climate change; and the linkage of forest and food production in the context of the REDD+ approach to valuation of forests. Part II, Managing Linkages Between Climate Change and Food Security offers a South Asian perspective on Gender, Climate Change and Household Food Security; a chapter on food crisis in sub-Saharan Africa; and separate chapters on critical issues of food supply and production in Nigeria, far-Western Nepal and the Sudano-Sahelian zone of Cameroon. Part III examines Food Security and patterns of production and consumption, with chapters focused on Morocco, Thailand, Bahrain, Kenya and elsewhere. The final section discusses successful, innovative practices, with chapters on Food Security in Knowledge-Based Economy; Biosaline Agriculture in the Gulf States; Rice production in a cotton zone of Benin; palm oil in the production of biofuel; and experiments in raised-bed wheat production. The editors argue that technical prescriptions are insufficient to manage the food security challenge. They propose and explain a holistic approach for adapting food systems to global environmental change, which demands the engagement of many disciplines – a new, sustainable food security paradigm.

Book Description :

Food security is high on the political agenda. Fears about societal insecurity due to food price increases and hunger, grave scenarios regarding the effects of climate change and general uncertainty about the impacts of investments in biofuels and so-call “land grabbing” on food prices and availability have meant that food security is now recognised as being a multifaceted challenge. This book is unique in that it will bring together analyses of these different factors that impact on food security. This volume will describe a range of different perspectives on food security, with an emphasis on the various meanings that are applied to food security “crisis”. The challenges to be reviewed include market volatility, climate change and state fragility. Analyses of responses to food security crises and risk will cover rural and urban contexts, arenas of national policy formation and global food regimes, and investment in land and productive technologies. This book is unique in two respects. First, it takes a step back from the normative literature focused on specific factors of, for example, climate change, agricultural production or market volatility to look instead at the dynamic interplay between these new challenges. It helps readers to understand that food security is not one discourse, but is rather related to how these different factors generate multiple risks and opportunities. Second, through the case studies the book particularly emphasises how these factors come together at local levels as farmers, entrepreneurs, consumers, local government officials and others are making key decisions about what will be done to address food security and whose food security will be given priority. The book will explore how food production and consumption is embedded in powerful political and market forces and how these influence local actions.

Book Description :

Climate change has a major impact on food security in Nepal. Almost all women farmers in the country depend upon agriculture as a major source of income to enhance their food security. There has thus far been no systematic study about the impact of climate change on food security of women farmers. Therefore to fill this lacuna, the present study was conducted in five Village Development Committees with 150 households of Udayapur district in Nepal. The present research aims to study the perception of farmers about climate change, the impact of climate change on agriculture and food security. It also documents the adaptation strategies that farmers practice. The study also attempts to study the agricultural policies through a gender perspective and identify the gaps in the policy. Both primary and secondary sources were used for data collection. The production of the major food crops like wheat, maize, rice, fruits fresh vegetables and livestock has been in relative decline since the past several years. Sometimes total crop failure occurred due to drought, excessive rainfall or an epidemic of insects, pests and diseases. The change in the climatic pattern has resulted in decreased crop productivity that increases food insecurity of the people. Farmers use different adaptation measures to cope with the adverse effect of climate change. These helped to minimise crop losses and improve the food security situation of women farmers by preventing crop loss. The national agricultural policy was found lacking in gender sensitivity. Based on the analysis of the data, recommendations have been made to the government.

Book Description :

Sustainable Intensification (SI) has recently emerged as a key concept for agricultural development, recognising that yields must increase to feed a growing world population, but it must be achieved without damage to the environment, on finite land resources and while preserving social and natural capital. It also recognises that all initiatives must cope with the challenges of climate change to agricultural production, food security and livelihoods. This multidisciplinary book presents state-of-the-art reviews of current SI approaches to promote major food crops, challenges and advances made in technology, and the institutional and policy measures necessary to overcome the constraints faced by smallholder farmers. Adressing the UN's Sustainable Development Goal 2, the various chapters based on evidence and experiences of reputed researchers show how these innovations, if properly nurtured and implemented, can make a difference to food and nutrition security outcomes. Case studies from around the world are included, with a particular emphasis on Asia and Sub-Saharan Africa. The focus is not only on scientific aspects such as climate-smart agriculture, agroecology and improving input use efficiency and management, but also on institutional and policy challenges that must be met to increase the net societal benefits of sustainable agricultural intensification. The book is aimed at advanced students and researchers in sustainable agriculture and policy, development practitioners, policy makers and non-governmental and farmer organisations.

Book Description :

This book analyzes potential yields of six major food crops - rice, wheat, maize, potato, soybean and rapeseed worldwide using both qualitative and quantitative approaches to study both China’s and global food security under climate change. Firstly, it reviews previous studies on potential yields of rice, wheat, maize, potato, soybean and rapeseed worldwide to provide a detailed information of studying on China’s and global food security based on the product’s supply and demand of these crops. Secondly, average and top (national) yields of rice, wheat, maize, potato, soybean and rapeseed since 1961 on global scale are employed to analyze their temporal and spatial variation trends and potential limits. Thirdly, the effects of global warming in climate change on both average and top yields of rice, wheat, maize, potato, soybean and rapeseed since 1961 at global level are analyzed using regression model, and their differences between average and top yields among these crops are identified and compared. Fourthly, the yields and per capita quantity of rice, wheat, maize, potato, soybean and rapeseed in major producer-countries and the world are analyzed to assess the situation and trend of international trade for the products of these crops, respectively. Fifthly, potential yields of rice, wheat, maize, potato, soybean and rapeseed worldwide by 2030 are projected using both trend-regressed models and ARIMA models to estimate the per capita quantity of these crops based on the projection of world population and assess the status of Chinese and global food security in that future. Finally, it provides policy implications and advice on food security for China and the world directing food production by 2030 under climate change.

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.

Book Description :

Climate change is one of the most important environmental challenges with its implications on food security, water supply, health, energy etc. The wheat production in the country is highly variable due to inter seasonal weather variability and has been projected to be 109 mt by 2020 which needs sincere efforts to mitigate the effect of climatic aberrations. Specifically, the main purpose of this study was to quantify the impact of changes in temperature, solar radiation and CO2 concentration that affect the level of wheat production. The impact of climate change on wheat production can be minimized through adaptability, varietal management and agronomic practices using CERES-wheat model. In Uttarakhand, wheat productivity accounted 15 % to 30 % more with the timely sown crop (20th November) than late sowing. Wheat yield has the positive correlation with CO2 concentration and negatively correlated with temperature. This book, therefore, provides a new metric of success for farmers to deciding agricultural operations and minimize the risks and extremely important to planners in the developing countries which will be the most vulnerable to the effects of global warming.

Book Description :

The effects of climate change can already be felt around the world, and they will likely impact all facets of human civilization—from health, livelihood security, agricultural production, and shelter to international trade. Since anthropogenic factors are mainly to blame for the current trends in global warming, human intervention will be necessary to mitigate it. With 17 authoritative chapters, Combating Climate Change: An Agricultural Perspective outlines a framework for preparing agriculture for climate change, presenting the causes and consequences of climate change and possible remediation measures. With contributions from internationally recognized scientists, the chapters cover global food security, adaptation of agriculture to fulfill its greenhouse gas emissions mitigation potential, economic aspects of climate change, the soil organic carbon pool, the need for agroecological intelligence, and the development of nutrient-use-efficient crops. The text also addresses genetic mitigation of climate change effects through the development of climate-resilient crops and the use of genetic and genomic resources to develop highly productive crop cultivars, as well as the conservation of native agroecosystems. Expert contributors discuss the impacts of climate change on plant pathogens and plant disease as well as on insects and crop losses. They address abiotic stress resistance, conservation tillage as a mitigation strategy, and more. The final chapter demonstrates the practical use of the WorldClim and DIVA software for modeling current and future climates, using Timor Leste and India as examples. Covering a broad range of issues related to climate change and agriculture, this book brings together ideas for environmentally friendly technologies and opportunities to further increase and stabilize global agricultural productivity and ensure food security in face of mounting climate challenge.

Book Description :

As the global population grows and incomes in poor countries rise, so too, will the demand for food, placing additional pressure on sustainable food production. Climate change adds a further challenge, as changes in temperature and precipitation threaten agricultural productivity and the capacity to feed the world's population. This study assesses how serious the danger to food security might be and suggests some steps policymakers can take to remedy the situation.Using various modeling techniques, the authors project 15 different future scenarios for food security through 2050. Each scenario involves an alternative combination of potential population and income growth and climate change. The authors also examine the specific test case of a hypothetical extended drought in South Asia, to demonstrate the possible effects of increased climate variability on a particular world region. They conclude that the negative effects of climate change on food security can be counteracted by broad-based economic growthparticularly improved agricultural productivityand robust international trade in agricultural products to offset regional shortages. In pursuit of these goals, policymakers should increase public investment in land, water, and nutrient use and maintain relatively free international trade. This inquiry into the future of food security should be of use to policymakers and others concerned with the impact of climate change on international development.
