Scientists say the notoriously dry continent of Africa is sitting on a vast reservoir of groundwater.

They argue that the total volume of water in aquifers underground is 100 times the amount found on the surface.

The team have produced the most detailed map yet of the scale and potential of this hidden resource.

Writing in the journal Environmental Research Letters, they stress that large scale drilling might not be the best way of increasing water supplies.

New York— The theme of this year’s World Malaria Day is “Sustain Gains, Save Lives: Invest in Malaria,” and the organizers carefully selected this theme to remind us that we must sustain progress against malaria to save lives.

In recent years, we have seen success in many regions: In Africa, malaria deaths have been reduced by nearly a third, and on other continents cases have been reduced by half.

Five thousand metres above the most biodiverse corner of the Amazon, tropical ecologist Greg Asner and his team see a kaleidoscope of colours among a mass of green.

Huddled in a twin-engine Dornier 228 aeroplane called the Carnegie Airborne Observatory, the scientists are capturing multicoloured images of the Peruvian rainforest canopy that verge on the psychedelic.

Ecological 'kings of the jungle' being toppled by forest fragmentation, severe drought and new pests and diseases

The biggest trees in the world, known as the true ecological kings of the jungle, are dying off rapidly as roads, farms and settlements fragment forests and they come under prolonged attack from severe droughts and new pests and diseases.
