“…In addition, our study also objectively considers potential trade-offs related to the water quality and ecological community composition. This is relevant to the framework of NBS, and in particular such GIS-based assessment tools as NCPT and NGPT [43][44][45], aiming to account for the combined changes in ecosystem services and the resulting gain in natural capital. Thus although the prospective of complete retrofitting of GRs in the case study catchments considered here may seem unrealistic due to the logistical and financial reasons (especially given that typically the roofs are of the pitched kind), this research, nevertheless, will be of use for practitioners planning new developments where the application of GRs and SuDS ponds is considered either simultaneously or as alternatives (such as, e.g.…”

This paper provides a summary of ecological functioning, biodiversity and water chemistry of two sustainable drainage systems (SuDS) ponds, and compares the level of ecosystem services with those attainable by retrofitting green roofs (GRs) in the ponds' catchments. These study sites are characterised by relatively high diversity of habitats, including aquatic, mesic and terrestrial; the importance of the latter is highlighted using the analysis of vascular plants and calcicolous lichens. Both SuDS sites provide valuable multiple benefits related to the enhancement of local biodiversity, water quality improvement and alleviation of flood risk, and the retrofitting of GRs would further enhance flood resilience and biodiversity of the area. However, there might be potentially negative effects on the runoff water quality and hydrobiological community composition of the receiving ponds. Changes in the runoff chemistry combined with the decreases in flush rate of high-flow events would increase the risk of cyanobacterial dominance during late summer and autumn. Such trade-offs should be carefully considered in planning any practical actions. This study elucidates indirect effects by following the methodological framework of comparative ecosystem analysis, which will be of use for any research and applications considering implementation of complex nature-based solutions (NBS), including those within the context of sustainable development of blue-green cities (BGC).
