This article, published by the WHO, assesses the potential for a global pandemic of A(H1N1) influenza, or 'swine flu'. The authors outline the properties of influenza viruses that are needed to create a pandemic and discuss population vulnerability and pandemic severity. They highlight the populations at most risk, for example people with underlying conditions such as cardiovascular disease, and the role that nutritional status and the quality of health services can play in influencing a pandemic's severity.

In assessing the 2009 swine flu outbreak, they draw attention to the fact that mutations often occur in influenza viruses, which means that while the emerging virus may be mild, it could return in several months in a much more lethal form.

The authors say that A(H1N1) is a new influenza virus not previously seen in humans or animals. They suggest that it is more contagious than seasonal flu, but note that outside Mexico where the outbreak began, the virus is causing very mild illness in otherwise healthy people. They emphasise the risk to people suffering from other chronic diseases and note that the WHO estimates that 85 per cent of these people are in developing countries.

This timeline, published by Nature, lists key dates and events in the 2009 outbreak of A(H1N1) influenza, or 'swine flu'. Drawing on information from the WHO, the US Centers for Disease Control and Prevention and others, it details confirmed and reported cases of A(H1N1), highlights the geographical spread of the virus and links to official documentation and key research findings as they are released.

This feature, published by The Lancet, discusses the world's capacity to cope with a A(H1N1) influenza, or 'swine flu', pandemic. The author outlines some of the progress made in pandemic preparedness since severe acute respiratory syndrome (SARS) and H5N1 influenza (bird flu) hit the world a few years ago, but points out that many countries' plans are flawed.

Many countries in the Asia–Pacific focus on early containment of disease and "social distancing", a strategy particularly important for developing countries as many lack access to antiviral drugs and vaccines. But, on the other hand, countries that focus on surveillance end up with problems if the virus becomes pandemic.

Scientists are struggling to predict what the likely health impact of a pandemic will be because influenza viruses can become more dangerous as they mutate. And epidemiologists are trying to assess which groups of people are most vulnerable and why some people have more severe symptoms than others.

This report, written for the Meridian Institute by a team of scientists from South Africa and Sri Lanka, describes the general issues facing projects aimed at improving access to clean water in the developing world, as well as the specific challenges facing nano-based projects.

The authors describe a number of water treatment devices that incorporate nanotechnology, including nanofiltration membranes, attapulgite clays and zeolites, nanocatalysts, magnetic nanoparticles and nanosensors. More importantly, they outline potential opportunities associated with these technologies, and possible risks.

The paper includes two case studies of projects designed to improve access to clean water — one in Bangladesh based on a conventional approach using sari cloth to remove cholera from water, and one in South Africa that incorporates a nanofiltration membrane.

This paper from the Meridian Institute describes a range of well-known and field-tested conventional approaches to removing contaminants from water as well as the current crop of nanotechnologies that could enhance existing — or develop new — water treatment technologies.

For each approach or potential product the authors give a short description of what it is and who has developed it, and report on the product's effectiveness in removing contaminants, the amount of water it can treat, and its cost and ease of use. They also include summary comparative charts of conventional versus nano-based treatments.

Conventional approaches covered include various types of filters, ultraviolet radiation, chemical treatment and desalination. Nano-based water treatments covered include carbon nanotube-based technologies, nanofiltration membranes and devices, nanoporous materials and clays, zeolites, nanocatalysts and magnetic nanoparticles.

This scientific article, written by researchers at Rice University in the United States, describes how magnetite (iron) nanocrystals — or 'nanorust' — can be used to remove arsenic from contaminated water. The authors describe the discovery of unexpected magnetic interactions between nanoparticles of rust that mean they can be easily extracted from water using a hand-held magnet.

Iron is well known for its ability to bind arsenic and the researchers' experiments show that by suspending the nanoparticles of rust in arsenic-contaminated water, arsenic levels were reduced to well below accepted standards for drinking water.

This feature article from Nanowerk, written in collaboration with scientists, provides a short introduction to the role nanotechnology could play in resolving water shortage and quality issues.

The authors describe how nanotechnologies are being used in water filtration, especially nanotechnology membranes incorporating carbon nanotubes and dendrimers. They also examine how nanotechnologies and materials such as zeolites, carbon nanotubes and biopolymers can be used to remove, reduce or neutralise heavy metals and other contaminants that pose a threat to human health. And they briefly discuss the issue of using nanotechnology to develop water disinfectants.

This commentary, by South African scientists Thembela Hillie and Mbhuti Hlophe, examines nanoscience's potential to solve the technical challenges associated with removing pollutants from water. The authors describe a range of nano-based water treatment technologies already in the marketplace and discuss how nanofiltration membranes can be used in low-cost methods to produce safe drinking water. They highlight a case study in South Africa where such membranes were used to treat brackish groundwater.

The authors emphasise the importance of technology transfer in getting nano-based solutions to the countries that need them, arguing that direct transfer does not often work. Rather, what developing countries need are approaches that combine technology transfer with technology adaptation and adoption — involving local stakeholders in establishing water treatment devices and developing local capacity to use them.

This fact sheet from the WHO outlines the basics about swine influenza, or "swine flu", including what it is, what its implications are for human health and how people become infected.

To protect yourself from swine flu, the WHO recommends avoiding contact with sick pigs or people, washing your hands regularly, practicing good health habits and following advice from local health authorities.

This series of reports, published biennially by the UN Food and Agriculture Organization, examines the current status of global forest resources and the role of forests in sustainable development. Each report includes one or more regional perspectives on forest resources and focuses on topical issues ranging from the potential economic benefits of forests to forest-based poverty alleviation to the links between forests and climate change.

The 2009 edition considers how forestry will have to adapt over the next 20 years to cope with variations in demand for wood products, environmental services, changes in forest sector institutions and developments in science and technology. It highlights the need to address imbalances in scientific and technological capacity by reducing barriers to international and inter-sectoral technology transfer, and mainstreaming environmental issues.

This report, written by climate change economist Stephen Seres and published by the UN Framework Convention on Climate Change (UNFCCC), analyses the extent to which projects funded by the UNFCCC's Clean Development Mechanism (CDM) contribute to technology transfer.

Although the CDM does not have an explicit technology transfer mandate, it contributes to technology transfer by funding projects that use technologies previously unavailable in host countries. Using data from over 3000 registered and proposed CDM projects, Seres finds over a third claim to involve technology transfer — of both knowledge and equipment.

Most of the technology originates from Germany, France, Japan, the United Kingdom and the United States. Some countries — including Bolivia, Ecuador, Kenya, Malaysia and Sri Lanka — have a much higher than average rate of technology transfer. Others, such as Brazil and China, have a much lower than average rate, although where there is technology transfer, it often extends beyond individual CDM projects.

This paper by scientists at the University of Hyderabad examines the nanoscience debate in India. Nanoscience's revolutionary potential and economic benefits are assessed against ethical, legal, social and environmental (ELSE) issues.

The authors present commercial applications, investment, risks and regulatory mechanisms, using the case of Bt cotton in India to show the implications of a new technology. They argue that India's diverse socio-cultural landscape means that nanoscience is likely to have uneven and multilayered effects.

India's scientists do not advocate regulation at the current stage of research — so as not to slow down development, say the authors. But they add that a broad-based and transparent regulatory body to address ELSE issues and funding for research on them would be beneficial.

This report, prepared by the World Water Assessment Programme under UNESCO (UN Educational, Scientific and Cultural Organization), assesses global freshwater resources including what drives the pressures facing them, how water is used, climate change's future effects on water supplies and options for improving water management for sustainable development.

The authors highlight the increasing demand for water, outlining the demographic, economic and social factors — such as population growth, international trade and changing lifestyles. They argue that climate change will undoubtedly affect water resources, impacting water quality and the frequency of extreme events such as droughts or flooding.

Investment in the water sector is important, say the authors — to improve access to clean water as well as decrease pollution from untreated sewage discharge. International donors must play a part in improving water infrastructure in the developing world, they add.

But how individual countries respond will depend on their own development objectives, capacity and political framework. The authors outline options for policymakers to increase supply, manage demand, reduce losses and reallocate resources.

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 article, written by scientists from Canada, China, Egypt and India, examines the spread of alliances in health biotechnology and the extent of collaboration in this sector between the South and the North.

The authors surveyed 288 firms on South–North health biotech collaborations and use the results to map the extent and geography of partnerships. They analyse the international collaborations of firms in Brazil, China, Cuba, Egypt, India and South Africa and compare them to South–South collaborations.

The authors conclude that developing countries' firms are closely tied to northern health biotech networks and that South–North collaborations are common practice in health biotech. More than half the firms surveyed actively collaborate with countries in the North — compared to just a quarter working with other developing countries. Egypt is the only country where South–South collaborations outnumber South–North ones.

This World Bank report describes the role higher education plays in building developing countries' capacity to participate in a knowledge-based world economy and outlines policy options to promote economic development. It confirms the shift in the World Bank's attitude to education support as a driver of socioeconomic growth.

The authors ask why higher education is important for development, how developing countries can best utilise their higher education systems, and how the World Bank and other donors can support local governments. They argue that knowledge is essential for development — and higher education is essential to create and apply knowledge.

They conclude that developing countries risk marginalisation because of their weak higher education systems, and stress the need for government and donor support.

This World Bank report examines higher education in Sub-Saharan Africa, asking how it can stimulate economic growth in the region. Drawing on international experience and regional case studies, the authors argue that there is an urgent need for countries in Sub-Saharan Africa to invest in human capital and knowledge — and therefore higher education — to create a viable and growth-promoting industrial system, and cope with threats such as disease, population growth and climate change.

They discuss how and why human capital investment can lead to socioeconomic growth and review current practices in Sub-Saharan Africa. The authors propose a number of good practices to help countries in the region strengthen their higher education systems quickly and effectively.

Recommendations include developing a national strategy for developing human resources, reforming funding mechanisms for higher education, giving institutions decision-making powers, encouraging diversity and developing postgraduate programs to boost local research capacity.

This opinion article highlights the need for donors to support higher education in poor countries. The authors, Jos H. C. Walenkamp and Ad Boeren from the Netherlands Organisation for International Cooperation in Higher Education, discuss how higher education and research can reduce poverty. They argue that it stimulates economic growth and increases a country's aid-absorption capacity.

They briefly state current aid agency and devolping country government attitudes to higher education and highlight brain drain as a particular problem that dissuades donors from investing in this area. They make a number of recommendations for the international donor community, suggesting that it unties bilateral aid, coordinates efforts and gives recipient governments responsibility to monitor and manage activities in their own countries.

These selected proceedings from a regional research seminar in Morocco, hosted by the UN Educational, Scientific and Cultural Organization (UNESCO), examine the state of higher education in Arab states. They highlight the impact of globalisation on local systems and discuss the role of funding agencies in supporting them.

The authors tackle a range of issues including the nature and extent of the 'knowledge gap' in Arab societies, current funding patterns and implications for future support, and the effects of international agreements such as the General Agreement on Trade in Services. Munir Bashshur, member of UNESCO's regional scientific committee for Arab states, presents a summary report of the conference, in both English and Arabic.

This paper from the Association of Commonwealth Universities outlines the commitments and activities made by major international partners — specifically the G8 countries — to developing African higher education between 2000 and 2004.

Projects are analysed by topic — from human resources development to HIV/AIDS to science and technology — and region. The authors highlight trends in donors' strategies for supporting African higher education, presenting development portfolios and case studies from France, Germany, Scandinavia, the United Kingdom and the United States, among others. They suggest improvements in aid delivery, including collaboration between donors and increased communication about individual donor strategies. They also call for more networking and collaboration across higher education institutions within Africa, while noting that these face financial constraints.

The authors conclude that there is a particular need for donors to provide more support to science and technology projects — as a crucial driver of socioeconomic development.
