    Iran

    Human-induced soil degradation is a serious and complex environmental challenge in Iran. For a long time, human activities, namely the overuse of land, have been influencing the natural processes on and in soils; therefore, various types of soil degradation can be observed in many parts of the country. The understanding and the consideration of direct and indirect effects of human activities on soils are indispensable for the prediction of the human impact on soil degradation processes.

    The density and diversity of woody plant species were studied within grazing, cultivation and charcoal production land-use areas in a multiple-use savanna woodland, central Uganda, using 75 plots with an area of 0.1 ha (Whittaker plots). Plant density was significantly higher under charcoal production (7131 ± 755 plants/ha) and cultivation (6612 ± 665 plants/ha) compared with the grazing lands (4152 ± 525 plants/ha).

    Integrating wildlife management into routine livestock operations has become a priority of many wildlife conservation agencies and nongovernmental organizations because grazing lands occupy more than one-third of the United States. We surveyed 1,093 beef cattle ranchers by mail to predict cattle rancher intentions to consider wildlife management in routine cattle management activities. We framed our survey using the theory of planned behavior, whereby attitudes, subjective norms, and perceived behavioral controls explain behavioral intent.

    Jordanie, Afrique septentrionale

    The dry rangelands of West Asia and North Africa are fragile and severely degraded due to low rainfall and mismanagement of natural resources. Rainwater harvesting (RWH) interventions are used to increase soil moisture content, vegetation cover, and productivity. However, adoption of rainwater harvesting by communities is slow. To understand adoption constraints and to develop options for sustainable integration of rainwater harvesting, a benchmark watershed was established in the dry rangelands of Jordan.

    Éthiopie

    In Tigray, Ethiopia, land degradation is a dominant environmental problem and hence the regional government has undertaken restoration measures on degraded soils since 1991. The present study was aimed to assess the impact of land uses and soil management practices on soil properties, and consequently on soil quality of degraded soils. The catchments selected were Maileba and Gum Selassa, and land uses included cultivated (CL), grazing (GL), plantation (PA) and area exclosure (AE). Replicated soil samples were collected from topsoil and profiles of four land-use types in both catchments.
