This report presents important environmental events and developments of 2012, and provides an overview of the status of key environmental indicators. It highlights the benefits of carbon storage in soil and the decommissioning of nuclear power plants as issues of emerging significance, and aims to strengthen science policy in these areas.

According to UNEP's executive director, although these may seem like separate issues, they go to the heart of questions about ensuring enough food and fuel while combating climate change and handling hazardous waste.

The report points out that the draining of peatlands is producing carbon dioxide emissions that amount to around six per cent of man-made greenhouse gas emissions; and their degradation is occurring 20 times faster than peat is accumulated. It also suggests that the nuclear industry needs to develop safer, faster and cheaper decommissioning of nuclear power plants.

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.

The report looks at the linkages between wetlands, human health and well-being, and examines the potential of to improving health while conserving wetland ecosystems. It aims to provide advice to wetland managers and decision makers, and to facilitate dialogue between wetlands and human health experts.

The report gives an overview of how wetland ecosystems influence health — benefits such as the provision of water, as well as hazards such as exposure to infectious disease. It outlines three approaches to harnessing the benefits of wetland ecosystems for human health. These include recognising the human needs satisfied by access to wetlands, such as water, food and social cohesion; medicinal plants and other health products; and the economic value of wetlands to improving socioeconomic conditions.

The authors call for a change in wetland management perspective, better policy development, and new instruments and approaches. They recommend stronger partnerships between sectors, governments and nongovernmental organisations.

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 report describes trends in the use of key resources such as water, food and biodiversity in Asia and the Pacific, and what this means for economies. It was produced by the UN Economic and Social Commission for Asia and the Pacific, the Asian Development Bank and the UN Environment Programme.

The report highlights how policy has changed over the past few years, driven by rising demand for resources and by climate change, and presents data on patterns of resource-intensive growth in the region. It outlines key policy actions for sustainable economic growth; and recommends strategies to improve the resilience of societies and economies, including changes in governance. The final section highlights the report's implications for the two themes of the UN Conference on Sustainable Development (Rio+20).

This report, produced by several UN agencies and programmes, presents tangible recommendations to prioritise and improve the management of the ocean ahead of the Rio+20 conference in June. It aims to provide context for discussions to take place at the conference, and to ensure that ocean and coastal management strategies are incorporated in the new sustainable development approaches that will emerge from Rio+20.

They include plans to mitigate and adapt to ocean acidification; create a 'blue carbon' market for carbon dioxide captured in the ocean; establish institutional mechanisms for protecting habitats and biodiversity not covered by national regulations; adopt a plan to help small island developing states transition towards a green economy; and improve the governance of ocean resources.

The report suggests that there is a strong case for the UN to lead by encouraging improved dialogue, coordination and cooperation among UN agencies, funds and programmes. This could lead to a proposal for a new mechanism for ocean coordination to be put forward at Rio+20.

This report provides a comprehensive overview of the current state of marine biodiversity and responses to environmental threats in islands in the central and western Pacific Ocean. This includes a description of known ocean characteristics in the region and a summary of country-specific climate change adaptation strategies.  

It provides a comprehensive account of environmental statistics and outlines threats to the marine environment in individual island countries, including potential (and perceived) impacts from environmental change (including climate change); habitat loss; invasive species; fishing pressure; sedimentation and increased nutrients from land-use activities.

The report highlights the lack of ocean science data, which makes development of mitigation strategies difficult, and states that improved data as well as human, technical and financial capacity are urgently needed to improve mitigation strategies. 

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 report presents 17 case studies of good practice in coastal management across island territories of the Asia-Pacific region. These illustrate examples of locally tailored, evidence-based and cost-effective actions at a local, provincial, national and regional level.

For each case study — including efforts in the Cook Islands, Fiji and the Solomon Islands — the report provides background information, intended outcomes and how they were addressed, what was achieved and lessons learned.

The report concludes that communities in the region can make progress with integrated coastal management to deal with primarily land-based threats facing coastal areas. It highlights the importance of enhancing the role of government and strengthening enabling environments; multi-sector partnerships; scaling-up small initiatives and achieving cost effectiveness; and providing information through education, awareness, monitoring or research.

This report presents two case-studies that illustrate problems arising from subsidising fertiliser and electricity for groundwater irrigation in India — a policy put in place in the 1960s to boost food production and food security. It aims to analyse why subsequent reforms of these policies have done little to resolve economic and environmental problems; identify reforms that could prove successful; and outline political processes that could help achieve them.

Using India's experience, it highlights political challenges of using subsidy policies that could also be relevant to other countries.

This analysis is based on a literature review and interviews with stakeholders. The report also presents the conceptual framework, and gives an overview of fertiliser policy in India: how it has evolved, the stakeholders involved in the political process, and the policy implications of subsidy reform. Case-studies of electricity supply in Andhra Pradesh and Punjab are used to demonstrate policy reform feasibility.

The report concludes that for both electricity supply and fertiliser policies, various reforms could be adopted that are unlikely to face significant political obstacles. It argues that experimental and research-based knowledge could be used more effectively.

This report explores whether solutions for biodiversity conservation and poverty reduction can reinforce each other. Working through diverse opinions on whether these links can be made, it provides answers to ten frequently asked questions around the issue and highlights their implications for policy.

The questions include which components of biodiversity are important to poor people; whether people living in poverty rely more on biodiversity than other people; how the poor can reap the benefits of biodiversity conservation; and whether poverty or poverty reduction contribute to biodiversity loss.

The report concludes with a list of ten policy implications, including the need to clarify the different definitions of poverty, biodiversity and conservation to ensure that complex issues are not confused and misrepresented; the value of giving greater policy attention to how biodiversity can prevent poverty; and the importance of including safeguards in the design of conservation policy and projects, to ensure that poor people do not end up worse off.

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 report presents the Framework for Assessing and Monitoring Forest Governance — an analytical framework that can help governments and other stakeholders describe, diagnose, monitor, assess and report on the state of a county's forest governance. It builds on the results of an expert workshop organised by the UN Collaborative Programme on Reducing Emissions from Deforestation and Forest Degradation in Developing Countries (UN-REDD) and the UK's Chatham House.

The framework aims to promote informed discussions about forest governance, drawing on approaches currently used or being developed. The report includes information about the framework's design, including a description of its components and a guide on how it should be used.

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 report, published to mark World Water Day 2007, reviews the multiple dimensions of water scarcity including increasing demand, competition and conflict and climate change. The authors consider opportunities for improving the efficiency of water use, suggesting the need to increase investments in water, value environmental services and build awareness of water scarcity among the general public.

This report presents a collection of regional perspectives that examine the environmental threats to the Indian Ocean's coastal areas, including sea level rise and storm surges, and explore the challenges facing decision makers, including limited funding and poor institutional infrastructure. The authors present opportunities for technological innovation and discuss how policies must integrate multiple sectors while reflecting local needs.

This report from the Convention on Biological Diversity presents case studies of 'ecological networks' — programmes that aim to maintain ecosystem functions while simultaneously using the landscape sustainably. The extent to which ecological networks conserve biodiversity while boosting socioeconomic development is assessed in eight cases across the world, including Asia and Latin America. The authors also discuss how ecological networks can contribute to meeting biodiversity targets, reducing poverty and addressing climate change.

This report examines the relationship between biodiversity, forest resilience and ecosystem stability in the face of climate change. The authors review ecosystem resilience and stability theories, and conclude that forests' capacity to withstand disturbance depends on biodiversity at multiple scales.
