The Africa Portal, part of the larger Africa Initiative project, is an online resource for policy-related issues in Africa, covering climate change, food security, energy and health, among other areas. It is published by the Centre for International Governance Innovation; Makerere University, Uganda; and the South African Institute of International Affairs. The website offers an open access publications library with more than 3,000 books, journals, and digital documents available online or to download. It also publishes opinion and analysis on current issues, a directory of experts on African policy, and announcements including events and grants.

This international HIV/AIDS charity dedicates a section of its website to traditional medicine, and with good reason — traditional medicines are especially popular with people who have HIV. The website provides advice for those seeking traditional remedies for HIV, lists potential therapies and highlights the role of traditional healers in combating HIV in Africa. It advocates that traditional healers are well placed to encourage HIV prevention, and convince people to get tested for HIV if they are at risk.

CHIEX investigates how climate variability affects human health in the tropical Americas. It runs projects in Brazil, Colombia, Cuba, Jamaica, Mexico and Venezuela, and focuses specifically on the spread of dengue fever and malaria in these countries. These projects have practical implications; for example, a study in Cuba led to the development of a "bioclimatological" monitoring system that uses climatic predictions to prevent and control disease.

The health gateway of the Climate Institute, which aims to help policymakers tackle climate change, has detailed notes on the resurgence of infectious diseases through global warming. These include vector-borne diseases spread through mosquitoes, ticks, triatomine bugs, sandflies and blackflies. It also looks at rodent-borne diseases, which are also set to increase as the climate changes — increased heavy rainfall can drive rodents out of their burrows and climate change is set to alter human migration patterns which could bring people into closer contact with rodents.

EVIPNet — a WHO initiative — aims to build capacity in developing countries to produce health policy briefs and national policy dialogues. It publishes policy briefs and research syntheses on health issues such as HIV prevention in Sub-Saharan Africa and health insurance for the Indian poor. EVIPNet links to tools, online tutorials and templates for writing policy briefs.

This foundation's mission is to reduce malnutrition through food fortification. It focuses on providing supplements — such as iodised salt — and healthy food to malnourished populations. The website includes downloadable fact sheets of GAIN's programmes around the world and overviews of vitamins and nutrient deficiencies.

The organisation targets vulnerable groups such as young children, pregnant women, people with infectious diseases, remote rural populations, or refugees. GAIN takes a business-minded approach to funding better nutrition, pooling its money with financial institutions, not-for-profit global venture funds and venture capitalists to encourage local businesses to develop new products, distribution channels and marketing approaches.

The Global Forum for Health Research provides evidence, tools and discussion forums for decision-makers in research funding and policy to improve the health of the poor. Although it covers issues for both infectious and non-communicable diseases, the agency recognises that mental health problems are severely neglected in developing countries. As well as links to various publications and reports, the website also hosts RealHealthNews, which aims to share news on research and interventions that can improve the health of those in developing countries.

Global Health Action is a free, online, peer-reviewed journal devoted to public health challenges. The journal, launched in 2008, aims to fill gaps in health information between rich and poor countries. Papers should address the global health agenda and include a strong policy or implementation component. The journal welcomes manuscripts from the developing world and may waive the publication fee for authors who are unable to pay. It also offers a manuscript mentorship scheme to less experienced researchers.

This partnership of government and non-government organisations, researchers, international bodies and the private sector has a much-called for goal: to increase cooperation between organisations involved different sectors such as health, climate, humanitarian assistance, ecosystems, research and operational services.

The partners collaborate on regional projects to increase capacity within the medical and environmental science communities; use rural communication networks to provide information to remote communities; and enhance the capacity of public-health services to predict and respond quickly to cholera, malaria, meningitis and other climate-sensitive diseases.

This website was created by the Consortium for Health Policy & Systems Analysis in Africa (CHEPSAA) — a partnership between African and European universities. It is a resource for educators, researchers, students and policymakers interested in health policy and systems research, which aims to understand and improve how societies organise themselves to achieve collective health goals, and how stakeholders interact in policymaking.

The website includes links to recommended reading, organisations, training opportunities and events, and teaching materials.

The Institute of Tropical Medicine provides training and research into tropical medicine and veterinary health care in developing countries. Its activities include studies on disease control and healthcare systems, education, clinical care, and support for governments and institutions involved in human and animal health. The website provides information about the institute's activities, including research in biomedical sciences, public health and clinical sciences. It also provides access to information about diagnostic supplies, and to resources such as blogs, networks and meetings about global health.

This philanthropic organisation works with the Pan American Health Organization (PAHO) and other partners in the Americas to administer health-related grants and implement programmes that provide medical supplies and equipment. It aims to mobilise resources to meet health, education, and training priorities in the region, focusing on chronic disease prevention, healthy aging, immunisations, neglected tropical diseases and health education. The website provides information on projects, partnerships and 'success stories', as well as updates on related news and announcements, including events, grants and jobs.

This organisation, established by Kofi Annan in 2004, promotes action on water and sanitation issues and monitor progress towards the Millennium Development Goal to halve the number of people without safe access to drinking water and sanitation by 2015. It publishes information from its meetings as well as an overview of the organisation's Hashimoto Action Plan, which outlines a set of action points for achieving water and sanitation security.

This part of the WHO's website focuses on the links between climate change and health. One factsheet looks specifically at climate change and infectious disease: it examines the historical evidence for links between climate and vector-borne disease, outlines different models to forecast climatic influences on infectious disease and offers examples of exactly how changes in climate can affect the spread of infectious disease. Another factsheet describes how to translate the science into useful policy decisions so will be particularly valuable for policymakers.

This website gathers together the WHO's reports and other documents on malnutrition and health, and highlights relevant meetings and conferences. It hosts the WHO Nutrition Landscape Information System that provides downloadable data on nutrition and nutrition-related health and development data in the form of country profiles. The profiles focus on nutrition-related indicators such as vitamin and mineral deficiencies and food security.

This website provides the WHO's latest strategic approach to traditional medicine, as well as reports and other publications that map out global usage and existing regulations. The organisation is working to ensure a tight regulatory framework, and strongly advocates for regulatory reform.
