Published: May 22, 2023

Primary considerations for urban blue-green infrastructure (BGI) encompass sustainable stormwater/urban heat management while biodiversity conservation is often considered an inherent benefit rather than a core planning requirement. However, ecological function of BGI as 'stepping stones' or linear corridors otherwise fragmented habitats undisputed. While quantitative approaches modelling connectivity in are well established, mismatches scope and scale with models that support the makes their adoption integration difficult across disciplines. Technical complexities have led to ambiguity around circuit network-based approaches, focal node placement, spatial extents, resolution. Furthermore, these computationally intensive, considerable gaps remain use identifying local-scale critical "pinch-points" planners may respond interventions address enhancement among other ecosystem services. Here, we present framework simplifies integrates merits regional assessments focus on areas prioritise reducing computational demands. Our facilitates: (1) potential at coarse scale, (2) prioritising based relative contribution individual nodes this network, (3) inferring hot- cold-spots interventions. We illustrate Swiss lowlands, demonstrating how, compared previous work, able identify rank different priority locations region how functional design be benefited by addressing specific environmental variables.

By infiltrating and retaining stormwater, Blue-Green Infrastructure (BGI) can help to reduce Combined Sewer Overflows (CSOs), one of the main causes urban water pollution. Several studies have evaluated ability individual BGI types CSOs; however, effect combining these elements, likely occur in reality, has not yet been thoroughly evaluated. Moreover, CSO volume reduction potential relevant components drainage system, such as detention ponds, quantified using hydrological models. This study presents a systematic way assess combinations mitigate discharge catchment near Zurich (Switzerland). Sixty combinations, including four elements (bioretention cells, permeable pavement, green roofs, ponds) different implementation rates (25%, 50%, 75%, 100% available sewer area) are for runoff routing schemes. Results reveal that provide substantial reductions; ponds potentially increase frequency, due prolongation. When from upstream areas is routed BGI, reductions differ cumulative achieved by types, indicating sum effects cannot accurately predict combined scenarios. larger consistently more cost-effective than small areas, since additional does outweigh costs. The best-performing combination depends on desired objective, being reduction, frequency or cost-effectiveness. emphasizes importance mitigation plans, highlighting their critical factors-BGI area, routing- offering novel approach develop tailored strategies catchments facing challenges.

Nature-based solutions (NBS) have co-benefits for water availability, quality, and flood management. However, searching optimal integrated urban-rural NBS planning to maximise at a catchment scale is still limited by fragmented evaluation. This study develops an optimisation framework based on the CatchWat-SD model, which developed simulate multi-catchment cycle in Norfolk region, UK. Three rural (runoff attenuation features, regenerative farming, floodplain) two urban (urban green space, constructed wastewater wetlands) interventions are into model range of implementation scales. A many-objective problem with seven management objectives account flow, quality cost indicators formulated, NSGAII algorithm adopted search portfolios. Results show that more significant impacts across catchment, increase implementation. Integrated can improve simultaneously, though trade-offs exist between different objectives. Runoff features floodplains provide greatest benefits availability. Regenerative farming most effective management, it decreases availability up 15% because retains soil. Phosphorus levels best reduced expansion space decrease loading combined sewer systems, this trades off against flood, nitrogen suspended solids.

Urban nature-based solutions planning for biodiversity outcomes: human, ecological, and artificial intelligence perspectives

Urban Ecosystems, Journal Year: 2024, Volume and Issue: unknown

Published: May 15, 2024

Abstract Nature-based solutions (NBS) harness ecosystem services for urban enhancement, promoting biodiversity, habitat creation, and water management while improving human well-being. However, decision-making often favours specific NBS designs, leading to uneven benefits distribution. Whereas human-centric design relies on convenience, financial sustainability, historical aspects, amenity increase through technical solutions, flora- fauna-centric (or eco-centric) targets spatial connectedness of blue-green spaces, in species richness, within centres. Both approaches can shape the biodiversity landscape, yet; they clash around planning priorities. Recent advances AI offer potential AI-centric planning, though its role remains unclear. This study examines interplay between across human-, eco-, domains, aiming balanced outcomes. We blended narrative, integrative, systematic literature review propose future steps more development. The findings this work suggest that presents an opportunity a applications climate change prediction, management, project visualisation. Incorporating into tools expedite modelling process, improve stakeholder communication, enhance outcomes By integrating human, eco, approaches, planners foster resilience sustainability implementation, ensuring equitable distribution landscapes.

Abstract Combined sewer overflows (CSOs), the discharge of untreated sewage mixed with stormwater into surface waters, are expected to increase under climate change as a result more extreme rainfall. Blue–green infrastructure (BGI), such bioretention cells and porous pavements, can help reduce amount entering combined systems, thus reducing CSO discharge. However, our understanding potential for BGI mitigate CSOs in future is still lacking, performance typically evaluated individual elements fixed implementation areas historical conditions or limited scenarios. In response, this study investigates 30 combinations rates prevent increases range scenarios an urban catchment near Zurich, Switzerland. Median total annual rainfall, projected by much 46%, could double median volume frequency up 52%. Four that include show most promise climate; given diverse responses distinct rainfall patterns, their enhance reduction across varying patterns. also likely become cost-effective climatic led larger reductions obtained through BGI. there trade-off between robustness cost-effectiveness, since capacity scales rate but cost-effectiveness declines.
