This report provides a policy framework for assessing the impacts of climate change on health, including vector-borne disease, by considering five challenges: informational, poverty and equity-related, technological, sociopolitical and institutional.

It begins with a detailed outline of climate science so far and the financial cost of adaptation. The informational challenges relate to better monitoring and surveillance to gather urgently needed data on disease and mortality in different regions, and early warning systems to predict extreme weather events and associated disease outbreaks. Technological challenges include the development of vaccines for diseases such as malaria and dengue fever.

How do policymakers tackle such challenges? A key move will be for government and non-government agencies, academia and civil society to collaborate internationally. Surveillance and primary health information systems in developing countries must be improved and local communities need to share adaptation strategies.

Adapting to climate change also means investing in food security, clean water supplies and reforestation. Policymakers also need to stimulate industry to develop low-cost methods for recycling wastewater and desalinating sea water. Mitigating and adapting to climate change, say the authors, has become inextricable from policies to eradicate poverty or closing the gap on social inequalities and health.

This feature article, published in the Environmental Science and Technology journal, uses the Cordillera Azul national park in Peru as an example to introduce mechanisms for reducing emissions from deforestation and forest degradation (REDD) that are under global discussion. 

The author discusses both the potential importance of and challenges associated with REDD projects. For example, although Cordillera Azul has been established as a national park by the Peruvian Government, funds for conserving it are still needed.

The article outlines some important milestones in progressing to an international framework for REDD, but notes that important details are yet to be resolved, such as how to ensure that beneficiaries of REDD funds deploy them effectively to protect forests.

The article suggests that active forest management is important and concludes with a brief introduction to the principle of proactive investment in natural capital (PINC) — the idea, promoted by the Global Canopy Programme, that forests should be regarded not only as a source of emissions, but rather as a public utility providing global ecosystem services that should be paid for.

This guide to reducing emissions from deforestation and forest degradation (REDD), published by the Global Canopy Programme, reviews many of the REDD proposals under discussion in global climate change negotiations.

The authors highlight why strategies for REDD are needed, then outline and compare the 32 government and nongovernmental proposals being considered by the UN Framework Convention on Climate Change (UNFCCC). They frame their analysis by examining the proposals in terms of scope, reference level, distribution mechanisms and financing options.

Visual comparisons are included to show where proposals agree and differ, and highlight areas with emerging consensus. For example, the proposals generally agree that reference levels should be set at a national level, and that a phased approach using a combination of different financing approaches could be most appropriate. Some challenges for reaching agreement on REDD measures and areas of current research are also highlighted.

The book includes a chapter summarising key research on REDD, including the Meridian Institute's Options Assessment Report, written for the Norwegian government, and several papers published by the Center for International Forestry Research (CIFOR).

This paper, prepared for the Global Urban Summit, proposes a framework for building climate change adaptation and mitigation measures into India's urban renewal programmes. This involves multiple government stakeholders at national, state and city levels.

The author begins with a description of the urbanisation trends in India and outlines the climate risks facing the subcontinent, including changing rainfall patterns and the potential for more drought, flooding and extreme weather events like cyclones.

The author outlines the vulnerability of urban populations and suggests that reducing it requires a public policy shift towards mainstreaming climate change risk assessment, adaptation and mitigation measures into ongoing national hazard mitigation programmes, and linking them to urban renewal in the largest cities.

Specific measures highlighted by the author include making building data public, building flood defences, strengthening existing infrastructure to withstand disasters and relocating highly vulnerable populations.
