In 2005, the World Health Assembly called on WHO member states to tackle their growing rates of cancer by developing rigorous cancer control programmes. To help guide the process, the WHO developed a series of six modules that provide practical advice for programme managers and policy-makers on how to advocate, plan and implement effective cancer control programmes, particularly in developing countries.

Individual modules focus on planning; prevention; early detection; diagnosis and treatment; palliative care; and policy and advocacy. As of May 2008, all but the one on policy and advocacy have been published.

Worldwide, cancer kills more people than HIV/AIDS, malaria and TB put together. In developing countries where chronic diseases are now growing alongside infectious diseases, new strategies need to be developed.

This article outlines how to develop an effective cancer strategy in African countries on the basis of discussions at the recent African Cancer Reform convention. A cancer control plan clearly needs to take into account African countries' financial constraints and the authors outline six key essentials that would offer most health gain for money invested. These are: setting up cancer intelligence units to collect data on cancer incidence; controlling tobacco use; early diagnosis and prevention; offering treatment wherever possible; palliative care when treatment is no longer useful; and training and educating future generations of African oncologists.

Developed countries can offer crucial expertise and experience and collaborate on cancer information networks. Educating local communities about a disease that is relatively new but growing quickly will also be essential to stop it spiralling when many cancers are preventable or treatable when detected early enough.

In 2003, the Gates foundation infused new vigour into global health efforts by declaring that the 21st century's "grand challenges" included developing new vaccines and overcoming drug resistance. This new grand challenges initiative, launched by a collaboration of top global chronic disease experts, identifies priorities in tackling diseases like diabetes and cardiovascular disease, and explains in detail how research should be directed to meet each challenge (a challenge was defined as a critical barrier that if removed would help solve an important health problem).

To distill the range of opinions and priorities, the coordinators sought input from 155 stakeholders from different countries and disciplines. The initiative requires the participation of agencies like the WHO, individual governments, and non-governmental organisations as well as civil society and business if it is to succeed. The authors point out that the Gates initiative was linked to large funding, whereas this project will rely on multiple funding agencies to coordinate on these priorities.

Global health experts have watched with increasing alarm as the waistlines of people in developing countries have started to widen with the adoption of a "Western" lifestyle. Obesity is of such concern because of its heightened risks for other diseases, such as heart disease, cancer, and diabetes.

In developing countries, the number of people with diabetes is set to rise to 228 million by 2030 from 84 million estimated in 2000. The link between obesity and diabetes is so strong because obesity renders individuals unable to properly process glucose — about 90% of type 2 diabetes is due to being overweight. Obesity and diabetes also raise the risk for cardiovascular disease and kidney disease. Diabetic nephropathy was the most common cause of end-stage renal disease in 9 out of 10 Asian countries, say the authors, which could be deadly for countries unable to cope with the health repercussions.

This draft policy brief says African, Caribbean and Pacific (ACP) countries can use local natural resources — such as sugarcane and jatropha — to meet energy requirements through biofuels, curtailing dependence on fossil fuels.

But the authors warn of challenges for developing countries, including economic and trade issues, and suggest practical steps for meeting these. They also present various bioenergy options for households, such as BioGel — a solid wood-substitute made from low-grade ethanol mixed with a gelling agent.

The brief makes a number of policy recommendations, including national strategies for promoting and sustaining local demand, and more funding for local and regional ACP research.

The African Union (AU) developed the African Model Law on Safety in Biotechnology to help countries across the continent fulfil their obligations under the Cartagena Protocol on Biosafety and manage related issues.

The AU encourages the development of a common position on biosafety regulation (see AU Biosafety Project) across the continent. It does not have the authority to legislate on behalf of its members — but it promotes the Model Law as a framework for individual countries to use in creating their own laws and institutions.

The Model Law is being revised through an ongoing consultation process before submission to AU governments for possible adoption at national level.

This study examines technology transfer in the Nigerian oil industry, focusing on how the Nigerian National Petroleum Company acquires technologies and accumulates technological capabilities. It examines the training efforts used to master imported technologies and looks at how technical change affects the company's production and financial performance.

This collection of seven policy briefs summarises recent research on the potential for transgenic improvement of banana and maize crops in East Africa. It is part of a series of briefings produced by the International Food Policy Research Institute and two other centres.

The collection provides a helpful overview of practical and inter-disciplinary research relevant to the two crops, and highlights key issues for evaluating the potential application of genetically modified technology.

The first article introduces the collection and highlights key issues. Subsequent articles assess the systems for disseminating new planting material and gauge the potential demand for transgenic banana and maize varieties in the region.

The last three articles look at biosafety risks and crop biodiversity.

In this discussion paper, Gregory Jaffe of the International Food Policy Research Institute (IFPRI) evaluates the biosafety frameworks of Kenya, Tanzania and Uganda against a set of nine basic principles that should characterise a "functional and protective" biosafety system. His analysis also takes into account the obligations laid down by international agreements such as the Biosafety Protocol, World Trade Organisation rules and the Codex Alimentarius.

The report recommends a number of specific improvements for each of the three countries' biosafety systems. The author also evaluates the scope for standardisation among the three countries, with a view to streamlining decisions and making best use of limited scientific and regulatory capacity.

The report will be particularly useful to policy-analysts, scientists, business-people and journalists in East Africa who want to know about the biosafety systems in the three countries, and to anyone who wishes to understand more about the basic principles of biosafety regulation in general.

This risk assessment for Africa, published last year, covers influenza outbreaks in poultry and their significance for human health, human cases of H5N1, vaccine research and development, the role of antivirals during a pandemic, World Health Organization (WHO) support for pandemic preparedness in Africa, and recommended priority actions for African nations. The priority actions are fourfold. First, that African nations collaborate with one another, forming close links between various health sectors. Second, that existing coordinating bodies expand their role to include pandemic influenza. Third, that the surveillance and response systems are improved with the support of the WHO Regional Office. Fourth, that mechanisms be put in place to communicate messages to the public and media.

This article analyses the ways in which African states might implement plant variety protection as part of their obligations under the Trade-Related Aspects of Intellectual Property Rights (TRIPS) agreement.

The report summarises the legal and institutional framework of intellectual property rights, examines the possibility of developing alternative regional and domestic systems, argues the case for sui generis plant variety protection systems, and highlights lessons from India concerning the development of such systems.

The author recommends that African — and should avoid the introduction of patents or plant breeders' rights.
