Using PESERA to manage desertification processes following wildfires in Gois and Ma(c)(a)o, Portugal
Wildfires are one of the main agents of land degradation and desertification processes in temperate subhumid ecosystems. There is an urgent need for integrated conservation approaches to reduce or prevent these problems. This work presents the innovative effort being made in the DESIRE research project to establish alternative land use and management conservation strategies in degradation-and desertification-prone areas following wildfires. The aim is to develop a practical application of operational methods, tools and models within a harmonized information system, in which the Pan-European Soil Erosion Risk Assessment (PESERA) model is included. This model is used to predict regional runoff and erosion at larger scales than field experimental sites. It offers the potential to improve land degradation predictions of water erosion, and is being applied to Portuguese DESIRE study areas (Góis and Ma(ca)o) to pinpoint the critical post-wildfire land uses and land management practices. We aim to develop strategies to halt degradation processes and reduce overall desertification risk using PESERA as an identification and evaluation tool.
