    Jordanie, Asie occidentale

    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 - and consequential surface runoff inevitably accelerates soil erosion and gullying.

    Jordanie

    Due to recurring droughts and severe overgrazing, Jordan’s dry rangelands are exceptionally prone to degradation. Establishing both restoration and sustainable rangeland management practices are crucial to reverse the negative impacts on the ecosystem. However, a primary estimate of the native baseline’s water and sediment fluxes is essential to properly target a sustainable transition from degraded to a potentially revegetated landscape status.

    In the United States 20% of privately owned rangelands are vulnerable to accelerated soil loss. Estimated annual costs of direct and indirect damage caused by soil erosion in the United States is $27 billion dollars. More than 50% of Asia and 70% of Middle Eastern rangelands are degraded. Exact estimates of economic costs and total area degraded is unknown; however, costs may be significantly higher than in the United States due to the extent of degradation/desertification in these regions.

    Éthiopie, Afrique, Afrique orientale

    Extensive land degradation in the Ethiopian Highlands jeopardizes rural livelihood. Intensified by increasing population pressure, farmers are forced to expand their arable land by deforestation and thus worsening the soil erosion problem. Through the application of various soil conservation measures, farmers and authorities try to prevent against further land degradation.

    Éthiopie, Afrique, Afrique orientale

    Land degradation through extensification of agriculture and overgrazing is an increasing problem across large expanses of the Ethiopian highlands that give rise to a loss in a range of ecosystem services. Ecological restoration through exclosure establishment has become increasingly important approach to reversing degraded ecosystems in Ethiopia and particularly in the Amhara regional state, northern Ethiopia.
