Natural Resource Management Approach to Flood Risk in Pembrokeshire

Project description: 

The increasing frequency and intensity of storm and flood events is compromising our ability to identify and determine areas of land in our urban centres which are suitable for ongoing development. Environment Systems was commissioned by Pembrokeshire County Council to assess the current ecosystem service regulating capacity across the county. The work is the first step towards developing catchment-based measures to help reduce flooding in towns in Pembrokeshire. Environment Systems used the SENCE (Spatial Evidence for Natural Capital Evaluation) tool to model the existing ability of the land across Pembrokeshire to prevent flooding. An ecosystem service stock map for flooding was created. A soil erosion model identified areas at greater risk of flooding. Using these in combination, a series of opportunities were identified. The resulting opportunity map shows locations where undertaking natural flood management measures would be preferential. This project has led to greater understanding of functioning ecosystems and how natural measures can be utilised to prevent flooding.
