This paper provides guidance for policymakers working on identifying low-carbon technologies, and discusses why they should put innovation at the centre of any green growth strategy. The authors argue that the need for innovation in the low-carbon power sector is critical in terms of preventing climate change and promoting development.

The paper explains the innovation process in the low-carbon power sector, and highlights participants and rules in the innovation process. It introduces the 'innovation ecosystems' approach — designed to capture the complexity of innovation processes — and to identify the services innovators need. The final section lays out a step-by-step process for identifying and making the most of opportunities in this sector. The authors conclude that innovation is key to using technology effectively and solving global problems requires everyone to live up to their potential as innovators.

This paper aims to identify key components of effective renewable energy policy in developing countries. It draws from published research and case studies in 12 countries in Africa, Asia and Latin America to provide recommendations on how countries can maximise international support for the development and deployment of renewable energies.

The authors argue that the global energy system needs to change, and that developing countries are at the forefront of this challenge because they are expected to contribute 80 per cent of the world's capacity for new electricity generation over the next two decades. The authors conclude that donors should move beyond funding individual projects to support nationwide initiatives for renewable energy.

The report looks at what developing countries are already doing to deploy renewable energy; gives an overview of key principles of renewable energy policy; discusses lessons learned from existing initiatives; and identifies areas where international support could help.

This report outlines the first coherent strategy drawn up by the UN to address dryland management, taking into account environmental concerns and the well-being of dryland communities. It examines the relationship between drylands and climate change, food security and livelihoods, and highlights ways in which the UN is working to mainstream drylands into policymaking processes.

Climate change is already having an impact on crop yields and nutrition in areas that rely on rain-fed agriculture, according to the report, and these impacts will intensify by 2020 in parts of Sub-Saharan Africa, Asia and Latin America. The impacts of climate change may be most pronounced in Sub-Saharan Africa and South Asia, suggesting that those already vulnerable will be affected the most.

A key message is that the international community has an opportunity to address the underlying causes of dryland degradation. The report concludes that global cooperation must be intensified if the ten-year strategic plan of the UN Convention to Combat Desertification — whose aim is to tackle desertification and degradation — and the Millennium Development Goals are to be achieved.

This paper, published by the UK-based Institute of Development Studies, examines how disaster risks associated with climate change might impact electricity generation and energy planning — which is an emerging research and development agenda. The authors argue that energy researchers and policymakers have overlooked how changing disaster risks could affect electrical power production.

The report assesses the vulnerability of nuclear power as well as several other options for energy generation — including oil, natural gas, hydropower and bioenergy — and identifies the implications for energy policy and planning. It lists recommendations as to how policymakers could take into account the link between disaster risk management and low-carbon development to improve the capacity of developing countries to build resilience. Suggestions include completing environmental impact assessments when siting new power plants, establishing better links between energy, climate, and disaster policymakers, and planning climate change adaption strategies for electricity production.

This safety guide, published by the International Atomic Energy Agency (IAEA), is designed to help countries prepare plans to improve their capacity to respond to nuclear or radiological emergencies whether as a result of an accident or malicious use of nuclear material. The guide can also be used to meet IAEA's safety requirements.

It outlines generic and operational criteria, according to specific radiation doses, to help policymakers decide between different courses of action to protect the public, emergency workers and the environment. It includes guidelines for assessing food and water contamination, and subsequent remediation measures, as well as on how to set safety perimeters around an incident depending on initial observations at the scene. The guide also outlines lessons learned from past experiences.

This working paper, published by the US-based Center for Global Development, outlines a market-oriented approach to funding the development and deployment of low-carbon energy technologies in developing countries. It describes how a green venture fund, with money coming from public and private investors, could help the development of green technologies suitable for use in low-income countries "in time to avoid catastrophic climate change". The authors discuss the commercialisation of these technologies; the structure and rationale of the funding strategy; and how the fund could operate, addressing key issues such as setting technology priorities, geographic focus, and the treatment of public and private investors.

This perspective article highlights some of the most proactive and innovative ideas related to water management and policy, including the concepts of 'virtual water' — water used to produce food that is traded — and the 'water footprint'. The authors discuss a range of issues, including water pricing, sustainability, water quality and alternative resources.

This report describes practices that small-scale farmers can use to adapt to climate change. The authors divide these practices into five categories: farm management and technology, farm financial management, diversification, government interventions in infrastructure, health and risk reduction. They conclude that farmers in developing countries are already using creative practices to manage climate challenges and that climate policies must strive to incorporate these.

This discussion paper describes the links between global climate change and ecosystem and animal health that researchers generally agree on and the impacts that, while less certain, are still likely. The author highlights gaps in current knowledge, emphasising the need for better disease surveillance and more localised climatological and ecological data.

The one bright note in global warming is seemingly that higher carbon dioxide levels will make food crops grow faster. More crops should equal more food. But, as this feature article emphasises, the story is not that simple.

Initial tests have shown that plants grown in high carbon dioxide environments could be less nutritious — with lower protein levels and a different type of protein produced. Other scientists have found a drop in key micronutrients such as chromium, selenium and zinc in high carbon dioxide environments.

Mitigating these changes can involve increasing nitrogen levels to offset protein deficiency, although not all scientists agree on this.

What is clear is that there is very little research in this area and past studies have only looked at carbon dioxide concentrations of 550 parts per million, which is lower than levels predicted by the end of this century.

This journal article, written by three researchers in Trinidad and Tobago, looks at malaria in the Caribbean. It asks why there are still outbreaks — including a big one in Jamaica in 2006/2007 — when the disease was allegedly eliminated in the late 1950s. The authors review malaria and vector data from across the Caribbean, summarising the pattern of imported cases as well as indigenous ones.

They identify three essential conditions for malaria transmission: presence of the vector, imported organisms and susceptible human hosts — all of which the authors show still exist across the Caribbean.

The authors suggest specific actions for regional policymakers to combat malaria. These include enhancing vector control skills, strengthening surveillance with new technologies, upgrading malaria therapy, increasing prevention strategies such as bed nets and raising public awareness of malaria. They emphasise that the role of climate change must be considered too, saying that rising temperatures could lead to new malaria vectors entering and colonising Caribbean islands and transmitting malaria on a major scale. But the authors are also careful to point out that the link to climate change is uncertain and remains contested in scientific circles.

Paul Reiter, a researcher on insects and infectious disease at the Institut Pasteur in France, is not convinced that climate change will cause a rise in malaria in tropical regions. In this opinionated review he sets out to dispel widely held "common misconceptions" about the effect of climate variability on future transmission.

To do so, he examines the history of malaria. He finds that in the past, contrary to expectations, climate has often not affected the transmission of the malaria parasite. Researchers claim that the Anopheles mosquito that carries the parasite cannot survive extreme temperatures, yet Reiter cites examples of the mosquito finding ways to adapt. In Sudan, for example, they can survive temperatures of over 55 degrees Celsius by hiding in buildings in daytime and only feeding after midnight.

Reiter's main disagreement with prediction models is that they only look at how one climate variable, temperature, is likely to interact with mosquito populations. Temperature, rainfall and humidity are interconnected and cannot be analysed separately, he says. The ecology of mosquitoes and humans is too complex to predict future malaria prevalence and incidence from temperature alone, he adds.

This opinion article, published by the Overseas Development Institute (ODI), argues that the real challenges to effective preparation for reducing emissions from deforestation and forest degradation (REDD) are creating robust governance and funding structures, not just capacity building.

The authors outline the practicalities of developing REDD mechanisms. They note that REDD could potentially mitigate the risk of climate change, conserve biodiversity and support development in forest areas. They express concern, however, that some approaches to implementing REDD projects have had limited success and note that reducing degradation can be particularly challenging.

The report concludes with suggestions for ensuring that REDD frameworks move from preparation to successful deployment. These include careful consideration of development implications for measures taken to promote reduced forest dependence and improve links between public and private finance to encourage complementary use of funds.

This report, submitted by the UN Food and Agriculture Organization, looks at how smallholder agriculture could help mitigate climate change. It focuses on soil carbon sequestration, which, say the authors, has high mitigation potential and is relevant to smallholders, although it is currently excluded from the Clean Development Mechanism.

One issue highlighted by the report is how to quantify mitigation through soil carbon sequestration. It proposes a combined measurement and modelling approach and the steps needed to implement this are discussed. These include creating a fund for pilot projects, agreeing field and lab protocols, establishing a common data archive and devising monitoring and evaluation methods.

The report also asks how carbon finance can be linked to the smallholder agricultural sector. It argues that enabling agricultural mitigation from developing countries will mean creating institutions that can aggregate carbon crediting among many stakeholders, facilitating the flow of carbon finance, building capacity and agreeing property rights to the carbon benefits generated.

This discussion paper from the South Centre and Center for International Environmental Law, discusses the international transfer of environmentally sound technologies within the UN Framework Convention on Climate Change (UNFCCC).

The authors present an overview of the UNFCCC's structure for negotiation, including the legal frameworks. They review the history of the technology transfer debate from the inception of the UNFCCC to the post-Poznan landscape and discuss relevant intellectual property agreements including the World Intellectual Property Organization.

They conclude that the expert group on technology transfer will continue to influence how technology transfer is treated within the UNFCCC and call on industrialised countries to recognise the real need for technology transfer and funds from developing countries, rather than using technology transfer as a political tool to bargain for binding mitigation targets.

This article, published by Mongabay.com, discusses the use of forest conservation to reduce greenhouse gas emissions from deforestation in the Amazon. The author describes the 'reducing emissions from deforestation and degradation' (REDD) mechanism included in the Bali roadmap for international agreement on climate change. He gives a brief history of REDD, explains how it could work and discusses complicating factors including land rights, measurement of deforestation rates, displacement effects of conservation and funding.

The author also discusses how promoting ecosystem services could provide a route to conserving rainforests, citing the example of Canopy Capital — a UK private equity firm that recently bought the rights to environmental services generated by a rainforest reserve in Guyana. He also examines other market incentives that could be used, including satellite surveillance to enforce conservation and certification for farmers following conservation rules.

This discussion paper, published by the International Food Policy Research Centre, examines the potential for mitigating climate change through carbon trading, with particular emphasis on Sub-Saharan Africa.

The authors provide an overview of global carbon markets, highlighting Africa's share in these, while outlining the obstacles African nations face in participating. They also assess mitigation opportunities in agriculture, land use and forestry in the region.

They conclude that Sub-Saharan Africa has much potential for mitigating emissions through forestry and cropland management, but action is constrained by existing capacity, funds, property rights and the price of CO₂ equivalents. They also suggest that integrating the region into global carbon markets will require new international capacity-building and advisory services, simpler rules for participating in the Clean Development Mechanism, access to emission allowances and credits, and more involvement in voluntary markets.

This collection of features and commentaries, published by Nature, reflects the broad spectrum of activities and opinions of members and associates of TWAS, the academy of sciences for the developing world.

With more than three dozen articles written by prominent scientists working on research or policy issues in the South, the collection examines a range of topics in science-based international development — from the relevance of subjects like mathematics or physics, to the increasing roles of biotechnology and renewable energy.

The achievements made and challenges still facing developing countries in key areas like agriculture, health, climate change and energy are also discussed. And evidence from across the South is presented to show how strengthening science can help achieve economic goals and what more is needed to ensure that knowledge and development are shared by all.

This paper discusses likely future changes in tropical cyclones, questioning whether they will become more intense following higher sea surface temperatures. The author outlines the different approaches currently taken to climate modelling and discusses the results of characterising current and future climate using the Max Planck Institute for Meteorology in Hamburg model, comparing them to observations.

Most climate models predict stronger tropical cyclones in a warmer climate, as an increase in latent heat provides more energy for the storms. But the author claims there is less evidence for a reduction in the frequency of storms in a warmer climate. Still, such a reduction could result from a general weakening of large-scale atmospheric circulation (which reduces the number of cyclones) caused by the rapid increase in water vapour that would follow a rise in global temperatures.
