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 special issue of the journal Philosophical Transactions of the Royal Society B: Biological Science explores how vaccines can fulfil their full potential for addressing global health challenges. It charts the progress to date, reviewing successes as well as challenges in the development and distribution of both human and veterinary vaccines.

The articles describe how vaccines can help mitigate and treat the world's major infectious diseases such as malaria, tuberculosis and HIV/AIDS, as well as chronic diseases, such as cancer. They explore vaccine policy and financing, ways to accelerate the development of new vaccines, issues surrounding public acceptance, and the logistics of getting vaccines to where they are needed. Also discussed is the use of vaccines to treat diseases in livestock — making an important link between health interventions, agricultural output and economic consequences.

The papers in this issue were presented at the meeting, 'New vaccines for global health', held at the Royal Society in London, United Kingdom, in November 2010.

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 paper aims to assess the suitability of using self-reported food security indicators to assess the welfare impact of the 2007–2008 global food crisis. It tests the usefulness of data from the Gallup World Poll (GWP) — a survey of self-reported food insecurity conducted before, during, and after the crisis — as an alternative to modelling estimates produced by the UN Food and Agriculture Organization, the US Department of Agriculture, and the World Bank.

The results suggest that although trends vary across countries, global self-reported food insecurity fell between 2005 and 2008, with the most reasonable estimate indicating 60–250 million fewer food-insecure people over that period. This trend contrasts with what was estimated by modelling-based methods. It is driven by rapid economic growth and limited food price inflation in China and India, among other heavily populated countries.

This report from PLoS Medicine argues that nanotechnology has a role in the development of low-income countries. The authors survey 85 experts worldwide and rank the top ten nanotech applications most likely to benefit developing nations. They outline how these applications can help meet the Millennium Development Goals. The paper calls for an initiative to identify "grand challenges" in nanotechnology for global health, which since the publication of this paper are now underway.

This follow-up paper, from the Journal of Nanotechnology Online, provides an in-depth look at the way poor countries engage with nanotechnology. It analyses why some developing nations are ahead of others in nanotechnology progress, and the challenges some less-developed countries face in shoring up nanotechnology capacity. It also investigates nanotechnology patent activity and assesses country participation in nanotechnology policy dialogues – for instance, China is a frontrunner in filing nanotech patents yet it is absent from policy discussions.

Mohamed Hassan at the Academy of Sciences for the Developing World (TWAS) argues that the nanotechnology boom will not lead to a divide between developed and developing countries due to the transformation of 21st century global science. Hassan says Brazil, China and India are swiftly developing nanotech capabilities. Instead, he warns of a South-South divide as poorer nations struggle to catch up. To avoid this, Hassan recommends that developing nations create networks between universities and research centres to share nanotech expertise.

The paper investigates the gap between the scientific or research community and the policymaking community in South Africa. It proposes a model of knowledge brokering as a means to bridge the gap and ensure the uptake of evidence in policy development and implementation. The model looks at the need for institutional mechanisms, such as knowledge-brokering offices in research organisations and government. It highlights the importance of researchers involving policymakers from the outset as well as increasing dialogue between these communities.

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 academic paper explores the Access and Benefit Sharing (ABS) system within the Convention on Biological Diversity (CBD). The authors highlight the principle challenges facing non-commercial biodiversity research scientists, in particular the tight regulations that restrict access to genetic resources in many countries and ultimately hinder the generation of knowledge vital to implementing the CBD.

In this Nature article, three members of the Royal Society call for an advisory group and a network of international laboratories to lay the groundwork for nuclear disarmament and international collaboration. Scientific collaboration has already helped nuclear negotiations, say the authors. But now, the technology needed to support disarmament must be developed.

In this Science article, US-based scientists Kristin M. Lord and Vaughan C. Turekian argue that science diplomacy is critical to US efforts to build positive relationships with foreign societies. They outline roles for US scientists to play — from acting as goodwill ambassadors to collaborating with colleagues overseas. And they highlight the importance of nongovernmental scientific organisations as conduits to foreign societies.

Writing in Cell, Nina Fedoroff, science and technology advisor to the US Secretary of State, calls on all US scientists and engineers to build partnerships with developing countries and improve the economic and educational opportunities within these nations. Scientists have a pivotal role to play in decreasing the disparities between rich and poor, she says.

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 series of articles considers the questions and conflicts surrounding the use of patent pools for antiretroviral (ARV) treatments for HIV/AIDS.

It provides background to the debate, considers individual proposals including the UNITAID patent pool, and offers regional perspectives on the suitability of patent pools to Africa, China and India.
