Discontinuities in hunter-gatherer prehistory in southern
The human history of southern Africa's drylands is a history of discontinuities. This paper identifies several instances where different kinds of discontinuity seem apparent and different kinds of approaches have been, or could be, taken to address them over the past 25,000 years (the approximate time-frame of the Later Stone Age).

Drylands of Africa Pose Unique Challenge to Acheiving MDGs
Sep 16, 2010· Dryland regions make up roughly 43% of the earth's surface. In Africa alone, it's over 60%, but despite this, decision-makers have generally neglected development of these regions. One of the main reasons is that drylands are assumed to be wastelands, with little potential, and in need of constant supplies of food aid. Contrary to this erroneous belief, the drylands have proven it can
