A methodology for assessing spatio-temporal dynamics of flood regulating services

The effects of land use alteration, migration and urbanization are key aspects in flood management, as human activities can strongly influence the capacity of ecosystems to provide flood regulating ecosystem services and determine their demand.This study analyzes spatio–temporal dynamics of flood re...
