The Challenges of Managing Water for Wetland Ecology, Flood Mitigation and Agriculture in the Upper Lunan Water, an Intensive Arable Catchment in Scotland

The “Water for All” project has aimed to develop a multi-disciplinary science case for adaptive management through a Payment for Ecosystem Services (PES) scheme in the Lunan Water, a lowland catchment in Scotland. Management needs for high and low flows, standing water levels and flow routing to/from high nature value mesotrophic wetlands were appraised. A key part has been the development of a real time hydrological-hydraulic model of the upper Lunan Water as an aid to management and scenario analysis especially with respect to existing and potential hydraulic structures. This provides better working knowledge and forecast-based simulations of high or low flow situations for catchment management planners, farmers, riparian owners and other local stakeholders. Engagement with local users and residents has included surveying Willingness To Pay (WTP) for hydraulic management as a function of governance mechanisms, development of a catchment management group, and interviews and workshops with riparian and other land-users. The work has highlighted the joys and sorrows of seeking to develop a PES approach and lessons to be learnt in project management, promotion of multiple benefits, catchment-scale water governance and the vices and virtues of “benign neglect”
