    Jordanian rangelands are a source of valued livestock produce, carbon storage, biodiversity, and medicinal plants. They also serve as watersheds that receive rainfall, yield surface water, and replenish groundwater throughout the area east and south of the western Jordan highlands. Appropriate land management, which is currently lacking, can protect and maximize these services for society. With the acceleration of desertification, land degradation and drought during the twenty-first century in the arid and semi-arid regions of Jordan, these services are becoming jeopardized.

    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. ICARDA and ILRI maintain these research sites and conduct field studies in Jordan and Ethiopia, respectively. The study plots are the size of a Landsat pixel (30-m X 30-m) to link local scale TLS to regional scale satellite imagery.

    Water scarcity and land degradation are widespread problems that affect agricultural productivity, food security and environmental quality in several parts of the world, particularly in the dry areas. Sustainable management of soil and water is necessary to optimize the use of limited rainwater for crop production and to decrease soil erosion. One management option is utilizing rainfall more efficiently through water harvesting. In arid areas, different types of water harvesting techniques (WHT) are being developed by

    The main objective of this study is to introduce the first consistent long ­term land cover database for Jordan. The Jordan National Land Cover Database (JNLCD) consists of four land cover maps for the years 1984, 1991, 1998, and 2014 that were developed at 30m resolution using a total of 11 Landsat TM/OLI satellite scenes. We primarily applied ISO DATA classification method and rule ­based method for refining misclassified classes. The overall accuracy achieved for the 1984 land cover map was 88% and for the 2014 land cover map was 93%.

    Jordan’s rangelands, the so called Badia, home of the Bedouins, are threatened through a combination of
    over-exploitation of the ecosystem services and a changing climate towards drier seasons and highly
    erratic rainfalls. In the recent decades, the once productive grazing lands transformed into sparsely
    vegetated and crusted desert grounds not capable of retaining the sporadic rainwater within the landscape
