Natural infrastructure for the recovery of ecosystem services for flood and mass movement risk mitigation

Abstract

The overall objective of the study is to identify actions involving natural infrastructure and suitable areas for flood risk mitigation and mass movements in the Rímac River basin. Factors that directly influence the determination of interventions and optimal areas for flood risk mitigation and mass movements in watersheds include Multicriteria Assessment Techniques and Geographic Information Systems (GIS), fieldwork, consultations with villagers and authorities of the peasant community at the basin level. With the information obtained through the Host Capacity Model and using official information and from WorldClim – GlobalClimate Data; a vector digital database was built that included altitude, slopes, plant coverage, precipitation, vegetation vigor, pathways, geological risks, susceptibility to mass movements, agricultural areas, potential areas for plantations. The resulting map shows the areas suitable for natural infrastructure interventions for flood risk mitigation and mass movements in the Rímac Basin.
