Multi-Risk Assessment to Evaluate the Environmental Impact of Outdoor Pig Production Areas: A Case Study

Outdoor pig production (OPP) can be considered an intensive system in many areas of the Mediterranean region. The concentration rainfall winter season, OPP’s topographic and soil properties, together with continuous input food pigs’ excreta, contribute to a profound increase nutrients leaching erosion. This work aimed evaluate accuracy DRASTIC-LU index Revised Universal Soil Loss Equation (RUSLE) provide early information improve planning this type through more adequate location sustainable management practices. two models were applied OPP 2.24 ha, heavy animal charge (one adult per 1.120 m2). results showed that 85% area has moderate risk vulnerability groundwater pollution 15% high risk. erosion ranged from very severe extremely 96% area. indexes RUSLE model produce multi-risk assessment agreed observed field data. These used for when choosing best improving practices systems.
