Climate Change Impacts And Adaptation Options In The Agrifood System

This paper summarizes the findings of the Working Group II contributions to the International Panel on Climate Change’s Sixth Assessment Report which runs into over 3 000 pages, focusing on the assessment’s conclusions and their effect on agrifood systems. The Assessment Reports of the International Panel on Climate Change (IPCC) are important as they provide policy makers with state of knowledge assessments on climate change, its implications, and potential future risks. These assessments also put forward adaptation and mitigation options.

This report assesses the cost of adaptation to climate change across a range of future climate scenarios and investment options. We focus on offsetting climate change impacts on hunger through investment in agricultural research, water management, and rural infrastructure in developing countries. We link climate, crop, water, and economic models to (1) analyze scenarios of future change in the agriculture sector to 2050 and (2) assess trade-offs for these investments across key Sustainable Development Goals (SDGs) for poverty, hunger, and water. Our reference projections show that climate change slows progress toward eliminating hunger, with an additional 78 million people facing chronic hunger in 2050 relative to a no-climate-change future, over half of them in Africa south of the Sahara. Increased investments can offset these impacts. Achieving this would require that annual investment in international agricultural research increase from US$1.62 billion to US$2.77 billion per year between 2015 and 2050. Additional water and infrastructure investments are estimated to be more expensive than agricultural R&D at about US$12.7 billion and US$10.8 billion per year, respectively, but these address key gaps to support transformation toward food system resiliency. Findings on ranges of costs and trade-offs and complementarities across SDGs will help policymakers make better-informed choices between alternative investment strategies.

Due to the urgent need to protect communities, ecosystems, and economies from the impacts of a changing climate, adaptation is becoming increasingly relevant. Climate change is already a significant stressor on most global and local value chains and threatens food security. This makes timely implementation of sustainable adaptation actions that catalyse agrifood system resilience indispensable for working towards better nutrition, better environments and better production, leaving no one behind. Recognizing the important role adaptation plays for agrifood systems, and its prominence in the Paris Agreement, the paper presents and reflects on FAO’s repertoire of different adaptation actions and solutions. Complementing the conclusion of the Global Stocktake at COP28, it comprehensively summarizes FAO’s efforts to boost progress in global adaptation actions. The paper (a) emphasizes the importance of bringing agrifood systems into the global adaptation agenda and policy landscape; (b) creates a cross-sectoral portfolio of FAO adaptation solutions covering multiple scales and approaches; (c) gives an insight into FAO's work with partners and Members and presents relevant networks and collaborations. Laying out FAO’s guiding principles according to the FAO Strategy on Climate Change 2022–2031, it underscores FAO’s efforts for transformative action in agrifood systems and demonstrates FAO's people-centered approach to climate change adaptation.

Climate change poses unprecedented challenges to the world’s food systems. Rising temperatures, changing rainfall patterns, and more frequent extreme weather events threaten agricultural production and the biodiversity and ecosystem services that underpin agriculture. Within food systems, climate change affects processing, storage, transport, and retailing of food and affects our food environments. These growing climate risks impact food security, nutrition, and human health, as well as equity and livelihoods, with poor food producers and consumers hit hardest. They make food systems a riskier source of income and reduce the availability of food — worsening poverty and inequity, disrupting livelihoods, and contributing to hunger and malnutrition. At the same time, food systems are failing to provide healthy diets for all, and are generating one-third of human-caused greenhouse gases. Solutions must address this complex nexus of problems. Climate change adaptation and resilience-building efforts for food systems must be accelerated to reverse growing malnutrition, ensure that all people can access healthy diets, and provide sustainable livelihoods. At the same time, efforts to transform food systems work to reduce their environmental footprint. Farmers and small businesses along food value chains in low- and middle-income countries will have to adapt their practices to a climate marked by extreme weather events and changing seasonal patterns in order to meet growing and changing food demand, while also contributing to mitigation. Support for this critical transformation requires not only the development, dissemination, and adoption of appropriate low-emissions, climate-smart technologies and practices, but also a focus on the policies, institutions, governance, and behavior change that can promote sustainable, inclusive food systems.

The impacts of climate change on agricultural systems and rural economies are already evident throughout Europe and Central Asia. This study, Reducing the Vulnerability of Georgia’s Agricultural Systems to Climate Change, provides a menu of options for climate change adaptation in the agricultural and water resources sectors in Georgia.

In farming systems across Canada, effective risk management is necessary to deal with drought, flooding, and extreme weather, and to adapt to altered climate and weather conditions. Unfortunately, climate change risks and opportunities are not always well understood among researchers and policy makers in the Canadian agri-food sector. This book addresses that gap by providing a wide-ranging synopsis of what climate change means for Canadian agriculture, exploring different approaches to the topic, and presenting examples of current research. It covers all agricultural regions and a wide variety of commodity production and farming systems. This comprehensive survey synthesizes twenty years of research on climate change and Canadian agriculture.

This report examines the economic and policy issues related to the impacts of climate change on agriculture and adaptation responses and to the mitigation of greenhouse gases from agriculture.

Ever-increasing population growth, combined with ongoing climate change signals that agriculture will face great challenges in ensuring global food security by 2050. Additionally, climate change-driven variations in mean sea level, wave conditions, storm surge, droughts, and river flows could have serious effects on agriculture and other sectors. Considering these factors and the extremely high value and necessity of agriculture worldwide, effective adaptation measures underpinned by reliable climate change impact assessments are essential to conserve soil and water resources and ensure food security. Sustainable Agriculture: Adaptation Strategies to Address Climate Change by 2050 provides a thorough examination of these issues, and presents in-depth analysis, practical case studies, and numerous examples of adaptation options throughout for various regions of the world. Features: Presents up-to-date, scientifically robust information on climate change projections in Europe, Asia, America, Africa, and Australia Provides pathways to sustainable agricultural options rather than just defining the climate change issue Includes case studies and practical examples throughout the world Presents a framework by which policymakers can begin implementing strategies for improving agricultural productivity
