Drylands have been cradles to some of the worlda (TM)s greatest
civilizations, and contemporary dryland communities feature rich
and unique cultures. Dryland ecosystems support a surprising amount
of biodiversity. Desertification, however, is a significant land
degradation problem in the arid, semi-arid and dry sub-humid
regions of the world. Deterioration of soil and plant cover has
adversely affected 70% of the worlda (TM)s drylands as a result of
extended droughts as well as mismanagement of range and cultivated
lands. The situation is likely to worsen with high population
growth rates and accompanying land-use conflicts.
The contributions to The Future of Drylands a" an international
scientific conference held under the leadership of UNESCO a"
address these issues and offer practical solutions for combating
desertification along with conserving and sustainably managing
dryland ecosystems. Major themes include the conservation of
dryland biological and cultural diversity and the human dryland
interface. This volume documents how our improved understanding of
drylands provides insight into the health and future prospects of
these precious ecosystems that should help ensure that dryland
communities enjoy a sustainable future.
