The two-day Africa summit in New Delhi last month opened a significant chapter in India's external affairs. Inaugurating the summit, attended by 14 African leaders, Prime Minister Manmohan Singh

According to an Assocham study, the lethal fake drugs market is growing at 25% annually.

Dust aerosols can suppress rainfall by increasing the number of cloud condensation nuclei in warm clouds and affecting the surface radiation budget and boundary layer instability. The extent to which atmospheric dust may affect precipitation yields and the hydrologic cycle in semiarid regions remains poorly understood. We investigate the relationship between dust aerosols and rainfall in the West African Sahel where the dust-rainfall feedback has been speculated to contribute to sustained droughts.

Spain plans to help five poor African countries fight hunger and climate change under a 60 million euro ($90 million) scheme to help the continent whose people flood to Spain in their tens of thousands each year. Spanish First Deputy Prime Minister Maria Teresa Fernandez de la Vega announced the aid package ahead of a Spanish-African women's conference opening on Monday in Niger, one of many African nations struggling to cope with high world food prices.

THE Chichewa people in Malawi have a saying: Njala ndi chilombo. It means "Hunger is a beast". Today, the beast is rampaging around the world and particularly Africa, where shortage of food threatens to undo recent economic and political gains. Climate change is partly to blame. But there is another less well recognised cause: long-term neglect has left African agriculture in a woefully inadequate state.

On Oct 17, 2007, Bill and Melinda Gates called for complete eradication to be adopted as the new goal for the age-old fight against malaria, with the Director General of WHO, Margaret Chan, promptly echoing their conviction. Although debate over the wisdom of this target will continue, growing impatience with the low ambitions of current efforts, fuelled by reductions in morbidity and mortality in some countries and progress in the development of new drugs and the first-ever vaccine, will lead many decision makers to adopt eradication of malaria as the primary aim for their organisations.

A continuous lake record elucidates how Saharan climate changed gradually from humid to today's desert conditions.

The first India-Africa summit, though late to come, holds a lot of promise in a number of areas.

INDIA, following the example of leading economic powers such as France and China, hosted an India-Africa summit for the first time.

Historically, there have been tenuous links between farmers and food producers, with many companies having scant knowledge of how and where their ingredients are grown. But as the prices of raw materials soar - from the barley used to make beer or the cocoa used to make chocolate - leading brewers and food manufacturers from Cadbury Schweppes to Diageo are increasingly recognising their businesses will benefit from investment in agriculture.

For years, food policy in the Middle East and North Africa was very simple: hydrocarbon exports paid for carbohydrate imports. Rising agricultural commodities prices and a large population increase mean that the traditional policy is now untenable even if crude oil trades at about $120 a barrel, forcing countries in the region, including Saudi Arabia, to reconsider how it feeds its population. "The region has woken up to the new food market reality," says Abdolreza Abbassian, an expert at the Food and Agriculture Organisation in Rome.
