Identifying the contribution of different land uses plays a crucial role in preventing erosion and prioritizing land management activities.This research aimed to assess the impacts of various land use scenarios on mitigating soil erosion in the North West Urmia region of Iran.In addition to the current scenario, 12 land use management scenarios were identified based on the observed trend in changes in echofix spring reverb land use patterns throughout the study area utilizing GIS.The RUSLE was used, and the necessary input parameters of the RUSLE model, were prepared.

The erosion mapping has been done using overlaying the input layers.The baseline scenario (current condition) resulted in an erosion amount of 17.22 (t/ha/yr).Introducing soil conservation techniques in dry farming on steep terrain, as depicted in scenario 6 (conservation and restoration of plowed rangelands), resulted in a reduction of the erosion rate from 17.

22 to 9.75 (t/ha/yr).On the other hand, scenario 20, characterized by severe rangeland degradation and overgrazing, exhibited the highest estimated erosion rate at 30.42 (t/ha/yr).

In contrast, the most substantial erosion reduction of 43.37% was evident in transpharm online shopping scenario 6 (conservation and restoration of plowed rangelands).It was observed that the P-factor (support practice factor) had a more pronounced impact than the C-factor (crop/vegetation and management factor) in mitigating erosion.These findings suggest the potential for utilizing a scenario-based framework to evaluate the impact of management scenarios on erosion and prioritize soil and water management measures and strategies.
