soil erosion in a given area depends on natural characteristics of the place as well as the rate of  human impact. in iran, the mediterranean precipitation regime and relatively high erosivity of rain, wide area of erodible soils/lithological formations, sparse natural vegetation in many regions and mountainous topography are main natural factors that affect soil erosion by water. accelerated s...

Arid ecosystems and deserts cover much of the Iran’s land. These areas are exploited by local communities. Considering the importance of the conservation and development of natural ecosystems in the arid regions, a study was done to assess factors influencing usage of rangeland conservation practices by exploiters through combination of survey methods and case study in arid rangeland of B...
