Abstract

This report describes changes to the PESERA model within the DESIRE project to incorporate

1. additional relevant processes, namely grazing, wind erosion and fire.
2. the soil and land management strategies that have been proposed for implementation in DESIRE (WB3)
3. proposed conceptual approaches for additional processes represented within PESERA that are linked to fine scale modelling advances (i) mass movements, based around a fine scale model developed by IRPI; (ii) sediment delivery, related to work by KUL on collating reservoir data, and including a report from KUL on their work
