This paper looks at how climate change could affect the rate of phenological development — biological events related to climate, such as flowering — and rainfall patterns during the growing season. The authors suggest that these changes may result in mismatch between water demand by crops and water availability from rainfall.
The paper describes a project that combines a new analysis of meteorological data with previously published data on climatic changes to assess the expected consequences of this mismatch for food security.
The authors illustrate how understanding how key crops might be affected by climate change in the Asia-Pacific region can help farmers, community workers and policymakers to prepare and adapt. Strategies include timing of planting, managing rainwater resources, use of new varieties, alternate crops and shifts in geographic distribution of crops.

This online book aims to offer insight into development issues related to climate change and indigenous peoples that can be useful in policymaking. It provides an overview of more than 400 relevant projects, case studies and research activities.
Different sections cover climate and environmental changes, including local observations, and the impact of these changes on indigenous communities. The book also outlines mitigation and adaptation strategies — based on traditional knowledge and survival skills — that are being implemented by them.
The authors highlight that climate change effects reported by indigenous people include loss of livelihoods; land degradation; impacts on food security; health issues; and water shortages that can affect agriculture, infrastructure, forestry and energy amongst others areas.

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 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, commissioned from the Pacific Institute by nongovernmental organisation Ceres, identifies and discusses the water-related risks in water intensive industries such as energy, mining, agriculture and pharmaceuticals. The authors discuss what companies can do to better evaluate and manage water risk and provide advice for potential investors.
This document, published by nongovernmental organisation WaterAid, highlights some of the key predicted impacts of climate change on water resources. The authors specifically address likely impacts in Africa and Asia, highlight the inequitable burden that climate change places on poor and developing countries, and suggest suitable adaptation strategies.

This factsheet from The Center for International Forestry Research (CIFOR) aims to answer common questions about the role of reducing forest emissions in tackling climate change.
This includes explaining why reducing emissions from deforestation and forest degradation (REDD) is important and identifying the four key challenges facing REDD projects — measuring carbon, making payments, accountability and funding. The authors summarise ongoing global initiatives to implement REDD, including the UN REDD Programme Fund and the Forest Carbon Partnership Facility.
A glossary of terms used in the debate is included as well as a list of facts and figures on key variables such as forest cover and forest loss. Contact details for some of the key people involved in CIFOR research are provided.

The third IPCC assessment report, Climate Change 2001, includes this section on the links between climate change and health. It offers a detailed look at how variations in climate, such as temperature or rainfall, could affect vector-borne disease. In particular, it evaluates computer models that predict climate impact on dengue fever and malaria. The assessment also looks at specific diseases such as leishmaniasis or schistosomiasis, explaining how the disease is spread and how changes in the environment might alter that spread.
The authors take a holistic look at the various factors involved. For example, in assessing schistosomiasis, they also consider the irrigation systems that will likely be needed to cope with expected water shortages resulting from climate change. The schistosomiasis parasite uses water snails as an intermediate host, so irrigation systems will need to be designed in such a way that they do not cause snail populations to multiply.
An update to the research on climate and vector-borne disease is also included in the fourth IPCC assessment report[796kB] although not in as much detail.
This Nature paper reviews evidence that a changing climate poses significant health risks and that global warming over the past few years has already increased illness and death worldwide.
Infectious diseases are strongly affected by climatic variations because the vectors that carry the bacteria or viruses do not have thermoregulatory mechanisms, say the authors. One of the most important existing sources of climatic variability is El Niño. This weather system has been shown to influence malaria in South America, rift valley fever in east Africa, cholera in Bangladesh and dengue fever in Thailand. If, as some scientists have suggested, climate change alters El Niño, the consequences will be significant.
The authors say there are some promising early warning systems for infectious disease. In Botswana, for example, two-thirds of the inter-annual variability of malaria can be predicted from sea surface temperatures and monthly rainfall.

As global temperatures rise, vector-borne disease is set to increase in the developing world but patterns will vary across countries. This review looks at how the prevalence of vector-borne disease will change in Africa, Asia, Australia, Europe, North America and South America.
As the authors explain, urbanisation levels will determine which diseases are likely to hit hardest. For example, dengue fever is a largely urban disease and will affect South America, where over 70 per cent of the population live in cities, far more than it will Sub-Saharan Africa, where less than 30 per cent of people live in urban areas. Malaria, by contrast, will have a bigger impact in Africa.
As ecosystems change, so will the distribution of vector species. Some will find their habitats expanded. A positive note is that most vectors cannot survive above about 40 degrees Celsius, so regions in which warming tips the temperature over this level could well see a drop in vector-borne disease — this is starting to be seen in Senegal, for example.
But the precise extent to which climate variability affects vector-borne disease is yet unknown, say the authors, which hampers evidence-based policy change.

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.
