Enhancing Resilience Of Dryland Agriculture Under Changing Climate

This contributed volume describes management practices based on interdisciplinary and convergence science approaches from different disciplines of agricultural science to enhance the resilience of dryland agriculture. The main focus of this book is to address the current issues and trends along with future prospects and challenges in adopting salient agricultural management practices in drylands globally under a climate-change scenario. Climate change and global warming have profound repercussions on increasing frequency, severity, and duration of droughts and/or floods, which may have implications for future productivity of dryland agriculture, e.g., more water shortages or abundances and high or low runoff rates, diminished crop yields, and reduced water productivity. In past few years, many technological advancements and management strategies have been evolved to tackle the climate-induced risks of dryland agriculture considering interdisciplinary and convergence approaches that integrate knowledge from multi-disciplines. This book is an attempt to bridge the gap in literature by unraveling controversies and characteristics of dryland ecosystems under the changing climate and dealing with detailed procedures of applying the advanced practices adapted to climate change for management of dryland agriculture. This edited book is of interest to ecologists, economists, environmentalists, geologists, horticulturalists, hydrologists, soil scientists, social scientists, natural resource conservationists and policy makers dealing with dryland agriculture. This book offers a broad understanding of dryland agriculture and assists the reader to identify both the current as well as the probable future state of dryland agriculture in a global context.

This book highlights the approaches for achieving trans-disciplinary research integration for “semi-arid dryland agriculture systems” under changing climates, while also identifying the elements of a collaborative research agenda that are needed to advance global food security. The book emphasizes climate change being a reality and how drylands are bearing the brunt in diverse ways. The major impact of dryland agriculture is on communities that need to: avoid the short- and long-term impacts of the changing climate; adapt strategies that can minimize these impacts; and be able to mitigate climate change, for which they need climate smart interventions. These interventions are only realized through knowledge and experience sharing among stakeholders from different sectors and backgrounds. It is in this context that the publication was seen as a necessity in order to bring together ideas that will transform lives and build adaptation capacities, thereby providing the much-needed products in communities leading to development

This volume discusses the need to adopt Climate-Resilient Agriculture (CRA) practices to address the increasing global impact that climate change has on agricultural productivity and agriculture-dependent communities. This approach applies technological, policy and economic measures to achieve sustainable agricultural growth in the sectors of grain, fruit, vegetable, fiber, feed, livestock, fisheries and forestry, with the ultimate goal of adapting and building resilience to climate change. The book also uses GIS, crop modeling and remote sensing techniques for future climate resilience applications in agriculture, and covers pest control measures that avoid the use of pesticides to boost crop and livestock productivity for improved food security. The book will be of interest to researchers and students in environmental science, climate science, sustainability and agriculture, as well as policy makers and environmental organizations.

Drylands are at the core of Africa’s development challenge. Drylands make up about 43 percent of the region’s land surface, account for about 75 percent of the area used for agriculture, and are home to about 50 percent of the population, including a disproportionate share of the poor. Due to complex interactions among many factors, vulnerability in drylands is high and rising, jeopardizing the long-term livelihood prospects for hundreds of millions of people. Climate change, which is expected to increase the frequency and severity of extreme weather events, will exacerbate this challenge. African governments and their partners in the international development community stand ready to tackle the challenges confronting drylands, but important questions remain unanswered about how the task should be undertaken. Do dryland environments contain enough resources to generate the food, jobs, and income needed to support sustainable livelihoods for a fast growing population? If not, can injections of external resources make up the deficit? Or is the carrying capacity of drylands so limited that outmigration should be encouraged? Based on analysis of current and projected future drivers of vulnerability and resilience, the report uses an original modeling framework to identify promising interventions, quantify their likely costs and benefits, and describe the policy trade-offs that will need to be addressed. By 2030, economic growth leading to structural change will allow some of the people living in drylands to transition to non-agriculture based livelihood strategies, reducing their vulnerability. Many others will continue to rely on livestock keeping and crop farming. For the latter group, a number of “best bet†? interventions have the potential to make a significant difference in reducing vulnerability and increasing resilience. This report evaluates the opportunities and challenges associated with these interventions, and it draws a number of conclusions that have important implications for policy making.

Climate change presents an unprecedented challenge to the productivity and profitability of agriculture in North America. More variable weather, drought, and flooding create the most obvious damage, but hot summer nights, warmer winters, longer growing seasons, and other environmental changes have more subtle but far-reaching effects on plant and livestock growth and development. Resilient Agriculture recognizes the critical role that sustainable agriculture will play in the coming decades and beyond. The latest science on climate risk, resilience, and climate change adaptation is blended with the personal experience of farmers and ranchers to explore: The "strange changes" in weather recorded over the last decade The associated shifts in crop and livestock behavior The actions producers have taken to maintain productivity in a changing climate The climate change challenge is real and it is here now. To enjoy the sustained production of food, fiber, and fuel well into the twenty-first century, we must begin now to make changes that will enhance the adaptive capacity and resilience of North American agriculture. The rich knowledge base presented in Resilient Agriculture is poised to serve as the cornerstone of an evolving, climate-ready food system. Laura Lengnick is a researcher, policymaker, activist, educator, and farmer whose work explores the community-enhancing potential of agriculture and food systems. She directs the academic program in sustainable agriculture at Warren Wilson College and was a lead author of the report Climate Change and Agriculture in the United States: Effects and Adaptation.
