River rehabilitation for the delivery of multiple ecosystem services at the river network scale.

摘要: This paper presents a conceptual framework and methodology to assist with optimising the outcomes of river rehabilitation in terms delivery multiple ecosystem services benefits they represent for humans at network scale. The approach is applicable globally, but was initially devised context project critically examining opportunities constraints on Scotland. spatial-temporal highlighted measure, scale, location stream network, service timescale specific could be used as initial scoping process planning levels delivered are based an expert-derived scoring system understanding how measure assists reinstating important geomorphological, hydrological ecological processes hence intermediate or primary function. permits “total long-term (>25 years) score” calculated which cumulative result combined effect number level over time. Trajectories time attaining score each measures also given. Scores weighted according societal values economic valuation. These scores decision making relation catchment scale directing resources towards alternative scenarios. A case study presented applying Eddleston Water Scotland using proposed options demonstrate value approach. Our overall assertion that unless sound frameworks developed permit evaluated part basin management, total benefit may well reduced. River together ‘vision’ within it can developed, fundamental future success management.
