This report lays out a set of policy recommendations for the sustainable intensification of agriculture and reduction of food waste to create a resilient global food system. Based on a review of scientific evidence, it pinpoints seven actions that policymakers — including those attending the UN Conference on Sustainable Development (Rio+20) — should adopt to foster sustainable agriculture and efficient food supply chains.

Recommendations include integrating food security and sustainable agriculture into global and national policies;

intensifying agricultural production while reducing negative environmental impacts; and creating comprehensive, shared, integrated information systems.

This policy roadmap will require the reshaping of food production, distribution and consumption patterns, and empowering vulnerable populations to build a sustainable global food system.

This report provides a visual overview of the trends and factors shaping global food and agricultural systems, including their interactions with broader environmental and socioeconomic concerns. It presents a selection of indicators on food and agriculture by country, aiming to be a reference point for policymakers, donor agencies, researchers, analysts and the public. These indicators are based on the FAOSTAT statistical database, which includes survey data submitted by countries, supplemented by national data.

Four sections cover provide an exhaustive overview of key themes: the state of agricultural resources, including pressures from demographic and macroeconomic change; food insecurity and malnutrition; the role of trade in meeting demands for food and feed; and the sustainability of agriculture in the context climate change and the need to provide ecosystem services.

This report gives an overview of climate change impacts on forests as part of a process to prepare management guidelines, based on a review of the literature and a survey of forest managers. It reviews how changes such as temperature alterations and availability of water might impact growth changes, wildfires, pests and diseases. The authors identify what is needed to create an environment that would support forest managers' efforts in mitigation and adaptation.

The document concludes that, although some forest managers are already taking measures to combat climate change, there is a lack of proper monitoring to assess their effectiveness, efficiency and impacts. It highlights that these measures are designed in response to perceived risks rather than incentive schemes such as certification. And it provides a number of recommendations for forest managers to better prepare for climate change.

This guidebook translates current knowledge on climate change and international climate policies into practical options for mitigation and adaptation in Africa, outlining the links with sustainable development. It is aimed at policymakers, decision-makers and other interested practitioners such as environment and climate change negotiators.

The guide focuses on potential climate change impacts on key sectors in Africa, such as small-scale farming. It highlights tools, methodologies and literature available to help countries assess mitigation and adaptation needs.

The authors outline the governance, technological, financial and capacity-building opportunities to take action on climate change, and how they can benefit development. The guidebook also includes sources of financing, and case studies on mitigation and adaptation, including rainwater harvesting, coastal zone adaptation, fisheries and restoration of degraded lands.

This report, which is part of the UN Foresight Initiative, describes the 21 most pressing emerging global environmental issues — those recognised as very important to well-being by the scientific community, but are not yet receiving enough attention from the policymakers. These cover a range of themes, from food security to biodiversity, energy and technology.

One of the most important cross-cutting issues identified in the report is the need to rethink international environmental governance. Other areas in need of improvement include the science–policy interface, and coping with incremental damage to the environment.

Improving food security in light of changing climate is also high on the list of priorities, with the report suggesting a need for more comprehensive early warning systems, support for smallholder farmers, efforts to reduce food waste and increasing agricultural efficiency. Other issues highlighted include managing the impacts of glacial retreat; improving ocean governance; accelerating the implementation of renewable energy systems; and considering the environmental implications of nuclear reactor decommissioning.

This technical report presents a tool designed to help understand the consequences of climate change on the coastal zone systems of the Asia Pacific regions, and examine long-term adaptation and mitigation strategies.

The tool comprises three components: a model of hydrological and biogeochemical processes, an impact assessment tool and a multi-criteria decision-making tool. It focuses on flooding, nutrients, salinity and sedimentation in the coastal areas of Australia, Bangladesh, Japan, Sri Lanka, Thailand and Vietnam.

The report presents the methodology used to develop the tool, results of case studies conducted using the tool, and key findings. It highlights that different countries prioritise flooding issues and adaptation measures differently. The case studies are ongoing, and are due to be expanded to other parts of Asia Pacific and to include other issues such as groundwater.

This report explains how acidification, warming and de-oxygenation are affecting the oceans, and encourages policymakers to mitigate these stressors and prepare appropriate policy statements ahead of Rio+20. It was written with the aim of raising awareness of ocean issues at the COP17 in Durban, South Africa.

The report provides definitions of ocean acidification, warming and de-oxygenation. It includes a guide to ocean impacts predicted to occur this century unless greenhouse gas emissions are substantially reduced, and how these impacts will, in turn, affect the climate via feedback mechanisms. It also outlines recommendations for mitigation, adaptation and research to improve understanding of these stressors.

This book assesses the vulnerability of fisheries and aquacultures in the Pacific in light of predicted climate change and variability. It examines how climate change could affect the region's plans to maximise socioeconomic benefits from this sector, which is already facing challenges related to population growth. It also offers recommendations — adaptations, policies and investments — on ways to protect these sectors.

The book describes the approach taken to conduct a vulnerability assessment and how the results can be used to help Pacific communities adapt. It provides practical guidance for learning about coastal and oceanic fisheries activities across the Pacific, and the ecosystems that support these industries. It stresses that sustainable use of fisheries is vital to the survival of communities in this region, and that this will only become possible with improved knowledge and information that can be factored into decision-making for sustainable development.

This report examines the challenges of managing water resources for agricultural use — specifically in the context of food production — in the face of a changing climate. It provides an overview of climate change impacts in different parts of the world, details options for adaptation and mitigation, and offers practical recommendations on how developing countries can cope with these impacts.  

The report outlines methods to assess impacts on water and agriculture, and stresses that water and agricultural policies must be more closely aligned. It concludes with suggestions for action to help countries in carrying out such assessments and adapting agricultural water management. These include using methods such as decision analysis to improve predictions; developing and applying downscaling techniques to build capacity for better analyses and climate adaptation; and coordinating analyses of the level of investment required for different solutions.

This technical report examines methods for assessing the vulnerability of wetlands — particularly in the context of climate change — as part of a broader set of methodologies for wetland inventory, assessment and monitoring. It gives an overview of available approaches to assessing vulnerability, including the frameworks available to incorporate climate change risks into development planning and projects.

The report identifies challenges and information gaps that have emerged from vulnerability assessments, including "multiple vulnerabilities" a lack of reliable data or long-term monitoring, and differing perceptions of the need to address wetland vulnerability. It concludes that to provide the information needed for sound management vulnerability assessments will need a better understanding of the complexity of interactive pressures that affect wetlands, such as land use and pollution; to develop appropriate metrics to assess vulnerability to multiple pressures; and to bolster data on the sensitivity and adaptive capacity of wetlands.

This year's edition of the report focuses on the costs of food price volatility, as well as the dangers and opportunities that high food prices present to poor countries. It outlines how food price volatility affects food security, offers policy options to reduce volatility cost-effectively, and suggests how countries can manage cost increases when they cannot be avoided.

A key message of the report is that increases in food prices are set to continue. The authors pinpoint contributing factors such as climate change-related increases in the frequency of extreme weather events, and stronger linkages between energy and agricultural markets because of growing demand for biofuels.

One of the key points made in the report is that large countries were able to insulate themselves from the crisis, but small countries dependent on imports, especially in Africa, were hard hit. Others include the importance of safety-net mechanisms for alleviating the impacts of food insecurity and laying the foundations for development, and that high food prices offer incentives for improving food security in the long term by increasing investment in agriculture.

This report highlights advances in the use of climate information to predict and prepare for climate-related natural disasters. It draws together 17 case studies that capture the current state of knowledge within the humanitarian community, and identifies research innovations. It presents the challenges and opportunities that disaster risk managers face in using climate science with a three step approach: indentifying the problem, developing tools, and taking action.

The results show that effective partnerships are crucial and can help to build the information needed for effective response. They also suggest how the use of this information can be improved — for example by focusing on immediate opportunities for action in countries and regions more likely to benefit. Recommendations also include developing realistic expectations, in order to maintain trust in the information and those who provide it, and encouraging national meteorological services to tailor their information to the problem at hand.

This report aims to identify strategies that the agricultural sector can adopt to mitigate and adapt to climate change, ensure food security, and improve the livelihoods of poor smallholder producers.

Agriculture is the main source of livelihood for poor people in developing countries, and improving agricultural productivity is key to achieving food security and meeting most targets set as part of the Millennium Development Goals. In Sub-Saharan Africa, climate change is adding to existing development challenges, making it essential that mitigation, adaptation and rural development strategies are developed together.

By focusing on the example of smallholder farmers in Kenya, the authors suggest "triple win" agricultural practices that promise the greatest payoff in terms of increased resilience of the agriculture sector to climate change mitigation, adaptation, productivity and profitability. They include irrigation, soil and water conservation, integrated soil fertility management and improved livestock feeding.

This report aims at encouraging increased trans-boundary cooperation in water resource management in Afghanistan and Central Asia, through a bottom-up, basin-based approach that adheres to the principles of Integrated Water Resource Management (IWRM)

The largest river in the region, Amu Darya, is crucial for the 43 million people who live in the Aral Sea Basin — but river flow and water availability are becoming increasingly unreliable because of the impact of climate change and inefficient water management. This is a security threat heightened by an expected 50 per cent increase in the region's population by 2025, says the report.

It calls for countries that rely on the Amu Darya — Afghanistan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan — to follow the IWRM approach to balancing competing demands for water, build trust and share practices at the local level by training experts from different countries in joint forums, and avoid multilateral agreements that involve management mechanisms too broad to be effective.

This set of factsheets presents key data on the impact of low carbon development on several areas linked to sustainable growth including poverty reduction; natural resource scarcity; 'green' jobs; transport; and fossil fuel subsidies.

Each factsheet synthesises the latest evidence from research conducted by institutions, consultancies and leading thinkers. The work aims to understand how investment in clean energy in developing countries can lead to economic growth. The first factsheet, for example, discusses how investment in small-scale, off-grid renewable energy can create jobs.

To illustrate the issues discussed, the factsheets use case studies from specific countries and projects. They use the phrase 'triple win' to indicate where low carbon development brings benefits in mitigation, adaptation and poverty reduction, and 'double win' where benefits are seen in two of these areas.

This report introduces the Climate and Regional Economics of Development (CRED) model — a climate vulnerability index that estimates the economic damage from climate change in nine world regions based on three measures: freshwater resources per capita, the share of population living in coastal areas, and the percentage of gross domestic product (GDP) of climate-sensitive economic sectors.

The report reviews the current literature of climate change vulnerability indices and describes the CRED climate model, including the data sources and methods used to create the index. It presents the results by region and compares them with the results of other indices. It concludes that although other indices contain more variables that produce more detailed results, they are more difficult to interpret. CRED indicators are quantifiable, can be updated when new information becomes available, and inform climate change policy by identifying regions and countries where intervention to prevent damages is crucial.

This paper reports the results of a systematic review of the impacts of climate change on crop productivity in Africa and South Asia. The study, funded by the UK Department for International Development (DFID), assessed eight food crops — rice, wheat, maize, sorghum, millet, cassava, yam, plantain and sugarcane — that make up more than 80 per cent of agricultural production in these regions. Its findings aim to inform DFID's policies, allocation of resources and other practices according to the need for a stronger focus on evidence-informed decision-making on agriculture in a changing climate. The report provides background information; a detailed account of the review protocol and methodology; the data extraction strategy; data collection; meta-analyses; a synthesis of results; and key findings for all crops organised by region. It recognises that climate change will worsen environmental conditions that already affect crops, such as heat, drought, salinity and submergence in water.

This background document presents scientific information on the effects of climate change on food production, and the implications for adaptation and mitigation efforts. It discusses how countries can manage the predicted average temperature rise of two degrees Celsius by 2100, which is enough to undermine farming systems. This will have major impacts on food security and rural poverty.

The report highlights two ways that countries can work towards adaptation. One is to better manage the agricultural risks of climate variability, for example using improved information services. The other is to speed up adaptation, with technological and policy tools for farmers.

It says that investing in technological innovation is needed to take full advantage of the agriculture sector's capacity to mitigate the impacts of climate change. This could include building monitoring systems for small-scale farmers.

Decision-makers and researchers working on climate, agriculture and food security should interact more to link knowledge with action, the report says.

This report outlines the local, practical experiences and lessons learned from the action research project Climate Change Adaptation and Disaster Risk Reduction (CCA-DRR). The goal of the project was to help local people analyse their own vulnerability to the impacts of climate change and work collaboratively to explore better adaptation practices.

It ran from 2008 to 2010 in three areas of rural Bangladesh where natural hazards occur frequently: Sirajganj on the Jamuna River, which is vulnerable to floods; Naogaon in the north-west, vulnerable to drought; and Patuakhali on the coast, which is vulnerable to cyclones, sea-level rise and salinity intrusion.

The report includes an analysis of the strengths and weakness of activities that mobilise local communities to adapt to the impacts of climate change. It concludes with several recommendations for future policy and implementation, and highlights that local people are best placed to understand changes in their environment.

This report, published by Forum For The Future and the UK's Department for International Development, explores the environmental, social, political, psychological and economic impacts of climate change on low-income countries over the next 20 years.

The report's central message is that development must be climate-resilient. It outlines four scenarios for 2030 (Reversal of Fortunes, Age of Opportunities, Coping Alone, The Greater Good) and sets out the implications of each imagined future for low-income country governments, policymakers, businesses and nongovernmental organisations. It covers a range of issues, including population, politics and technology, and is designed to be a practical tool for policy- and decision-making, with exercises and supporting materials.
