Land degradation resulting from improper land
use and management is a major cause of declined productivity
in the arid environment. The objectives of this study were
to examine the effects of a sequence of land use changes,
soil conservation measures, and the time since their implementation
on the degradation of selected soil properties.
This Country Environmental Analysis
(CEA) has been developed by the World Bank in cooperation
with the Government of Jordan. It aims to integrate
environment into development and poverty reduction

Groundwater development and use have proceeded rapidly in recent years, often outside of governance frameworks. As a result, unrestricted pumping and pollution have led to threats to the sustainability of aquifers, and the allocation and use of groundwater have often been poorly aligned with society’s goals for equity, sustainability and efficiency.
The University of Tennessee’s Dept. of Geography in collaboration with ICARDA, ILRI, USDA-ARS, and Cornell University’s Dept. of Natural Resources collected TLS data in the cold desert shrub-steppe ecosystem of the East Bank Plateau of Amman, Jordan and in mixed Acacia-Commiphora woodlands of Borana Plateau in southern Ethiopia.
