this is the voa special english development report.

the sahel is the area of africa that lies between the sahara desert to the north and more fertile land to the south. the dry plains of the sahel are mostly treeless. yet in niger, one of the nations along the sahel, millions of trees are now growing.

researchers have been studying the progress of a re-greening campaign in niger. chris reij is a scientist from the netherlands. in a message at frameweb.org last february, he described how, in some places, "densities are so high that you almost look at a wall of trees."

a united nations news service reported in october that niger's government said the campaign had already reclaimed three million hectares. teams of workers have used simple methods such as planting trees and protecting natural vegetation to save land from being lost to desert.

ten to twenty times more trees were reported in parts of southern niger in two thousand five than there were thirty years earlier.

some reclaimed land can now be farmed again. the land became infertile during the nineteen seventies and early eighties. but about twenty years ago, local farmers recognized that their once-productive soil was being carried away by severe winds.
