Understanding And Mitigating The Impact Of Climate Change On Insect Pests And Food Security

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.

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.

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 study warns that climate change may increase the risk of pests being introduced to new areas. It recommends conducting pest risk analyses and strengthening international cooperation as preventive measures to protect plant health.

The authoritative overviews in this volume provide a wealth of practical information on current approaches to the study of insect-plant interactions. Methods described include direct behavioral observation; assays of host finding, oviposition, and feeding behavior of insect herbivores; post-ingestion physiological effects; measurement of food quality and sensory responses of insects to plant stimuli; chemical isolation and identification of active phytochemicals; evaluation of plant resistance to insects; and the biochemistry of allelochemic interactions.
