Water Scarcity In The Sahel

Water Scarcity In The Sahel


Sitting on the shores of Lake Debo, the vast body of water at the heart of the River Niger's inland delta, the Malian village of Guidio seems well positioned to withstand the effects of drought. Unlike many other villages in the Sahel, the semi-arid region flanking the Sahara, it has an apparently plentiful supply of water on hand to raise crops and a back up if the drinking wells run dry.


Yet for Guidio's inhabitants, water is now becoming a daily concern. "Before we had enough rain and we could grow anything," says Moussa Guindo, a farmer who has lived in Guidio all his life. He gestures to the dusty ground. "When I was a child, where we're sitting was in the river. Now look: it's the middle of the village. Sometimes the rain starts, but then it doesn't last and the places where we used to be able to grow we can't anymore."


Guidio is a microcosm of the problems being felt up and down the Niger. West Africa's gr…

Acute Water Scarcity At Wettest Place On Earth

Acute water scarcity at wettest place on Earth

Meghalaya India, the wettest place on Earth is now known as a wet desert due to water scarcity. Has climate change also now even reached the most hidden pristine parts of our world?

From the article:

Nothing can be more ironical: despite being the wettest place on earth Cherrapunjee is suffering from acute water scarcity, earning for itself the epithet wet desert. And now the Energy and Resources Institute (TERI) is assisting the Meghalaya government to go into the causes of the scarcity, especially during the lean period.

The study will include technical assessments on the status of river catchments in Meghalaya and social and institutional analysis of the forces that have led to the shortage of water, says Jevon Harding of TERI. TERI will assist the Rain Water Harvesting Mission, formed by the state government, to combat the shortage of surface water. One of the components of the study will be to come up with a strategy of rainwater harvest…

Tibetan Glaciers Melting Rapidly

Tibetan Glaciers Melting Rapidly

Glaciers high in the Himalayas are dwindling faster than anyone thought, putting nearly a billion people living in South Asia in peril of losing their water supply.

Throughout India, China, and Nepal, some 15,000 glaciers speckle the Tibetan Plateau. There, perched in thin, frigid air up to 7200 metres above sea level, the ice might seem secluded from the effects of global warming.

But just the opposite is proving true, according to new research published in the journal Geophysical Research Letters.

Professor Lonnie Thompson of Ohio State University and a team of researchers travelled to central Himalayas in 2006 to study the Naimona'nyi glacier, expecting to find some melting.

Mountain glaciers have been receding all over the world since the 1990s and there was no reason this one, which provides water to the mighty, Indus, and Brahmaputra Rivers, should be any different.

But when the team analysed samples of glacier, what they found stunned them.

Radioac…
