Sahara desert frontiers turn green
bbc.co.uk -- Satellite pictures of northern Africa show that areas lost to the Sahara desert during decades of drought are turning green again.
Analysis of images show deserts retreating in a broad band stretching from Mauritania to Eritrea, according to research in British magazine New Scientist.
The driving force behind the retreat of the deserts is believed to be increased rainfall.
Better farming methods have also played a critical role, according to researchers.
Twenty years ago, severe droughts turned much of northern Burkina Faso into a desert.
But satellite surveys of the region have shown that vegetation is returning to the country - and, indeed, across the southern edge of the Sahara desert.
The surveys were funded by Dutch, German and American aid agencies, and will be presented to ministers in Burkina Faso later this year.
And new comparisons with archived images also show increasing grassland and forest vegetation in southern Mauritania, north-western Niger, central Chad, as well as in Sudan and parts of Eritrea.
And the researchers say that while overall improvements have been steady, dramatic progress has been made in particular villages and areas, particularly those where donor agencies have invested consistently in soil and water conservation.
One particularly successful farming technique is known as "contour bunding". It consists in placing lines of stones along slopes and contours on the land to help rainfall soak in, and to stop topsoil washing away.
And that is helping to transform thousands of hectares into productive fields - where nothing grew just a decade ago.

Congo, Uganda Sign Peace Deal
LUANDA (Reuters) - The leaders of Uganda and the Democratic Republic of Congo have signed a deal to help bring peace to the former Zaire, where four years of civil war have left around two million dead. Ugandan President Yoweri Museveni and his Congolese counterpart Joseph Kabila signed the accord late on Friday in the presidential palace in Angola's capital Luanda, witnessed by Angolan President Jose Eduardo dos Santos. Diplomats said the accord committed Uganda to withdrawing its remaining troops from the central African country of Congo, where they have been fighting alongside rebels opposed to the Kinshasa government. Congo, in turn, pledged to take action against rebels based in the east of the huge, mineral-rich country who are hostile to the Kampala government. "The government and I myself have the firm determination to cultivate this friendship so that the generations to come can find the normal strengthening of the ties between peoples and nations," Kabila said in quotes carried by the Portuguese news agency Lusa. "This is an important accord," Museveni said. "Africans need work, to increase the tax base, to develop education and health -- objectives that cannot be attained while there is war."
