The desert is dying
In places more than 50% of the mature trees have disappeared between
1965 and 2003, while almost no new trees have been recruited. Despite extreme aridity the main cause of tree mortality seems not to be climate, but commercial charcoal production.
This indicates that the traditional and sustainable indigenous resource management, which desert people have developed through millennia, is changing.
Desertification has been recurrently discussed and questioned since the 1970s. The focus has been on desert borderlands, while changes in sparse but important vegetation resources within the desert core have been neglected.
This study will be published on February 14, 2007 in PLoS ONE, the international, peer-reviewed, open-access, online publication from the Public Library of Science (PLoS).
