The combination of urbanization and global warming leads to urban overheating compounds the frequency intensity extreme heat events due climate change. Yet, risk can be mitigated by green-blue-grey infrastructure (GBGI), such as parks, wetlands, engineered greening, which have potential effectively reduce summer air temperatures. Despite many reviews, evidence bases on quantified GBGI cooling benefits remains partial practical recommendations for implementation are unclear. This systematic literature review synthesizes base mitigation related co-benefits, identifies knowledge gaps, proposes their maximize benefits. After screening 27,486 papers, 202 were reviewed, based 51 types categorized under 10 main divisions. Certain (green walls, street trees) been well researched capabilities. However, several other received negligible (zoological garden, golf course, estuary) or minimal (private allotment) attention. most efficient was observed in botanical gardens (5.0 ± 3.5°C), wetlands (4.9 3.2°C), green walls (4.1 4.2°C), trees (3.8 3.1°C), vegetated balconies 2.7°C).

Abstract Blue-green infrastructure (BGI), combining semi-natural and engineered elements, offers multifaceted benefits like stormwater management, water purification, heat mitigation, habitat provision. However, current BGI designs prioritize engineering goals, overlooking its ecological potential. Here we advocate for integrating objectives into design to enhance performance biodiversity. Through an interdisciplinary literature review, emphasize the importance of species diversity, abundance, processes, improve resilience, lower management costs. We collaboration navigate trade-offs between objectives, ultimately enabling us engineer both with

Abstract Decades of research on multifunctional Green Infrastructure (GI) has yet to translate into holistic implementation in the built environment. This oversight stems from assumptions that many ecosystem services occur passively and thus potential synergies are overlooked during planning design. study offers specific guidance for coordinating GI planning, design, construction by examining current state academic literature these aspects. It identifies 15 elements (e.g., green roofs) objectives biodiversity) collectively consider before implementation. The tends isolate discussions “engineered” with water-related objectives, while more “natural” linked biodiversity human well-being. Coordinating across remains imperative, but evaluating too options risks a paradox choice. recommends short-term adherence principles adaptive design and, long-term, reemphasizes multifunctionality assessments, inter transdisciplinary collaboration, political will.

Urban heat islands (UHIs) pose a significant challenge in cities worldwide, exacerbating energy use, air pollution, and health risks. This paper reviews the role of water bodies mitigating UHI effects, which is vital for informed urban planning climate adaptation. We analyze how features, particularly when combined with green spaces strategic design, can significantly cool environments. The effectiveness reducing temperatures influenced by their size, shape, surrounding land climatic conditions, vegetation. Empirical research case studies indicate that larger well-shaped bodies, due to extensive surface area continuous evaporation, are more effective. Furthermore, integration enhances cooling through increased evapotranspiration shading. review highlights placement design within landscapes as crucial maximizing benefits.

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.

Using systematic review methods, this study aimed to provide an overview vegetation engineering systems being researched applied that combine planting urban management. We also sought identify positive as well possible negative impacts on hydrology health. It has been shown diverting rainwater from impervious surfaces pits considerable potential for improving health reducing drought stress trees. Worldwide approaches optimizing infiltration water supply are promising. Different substrate types have tested, generally show good vitality, although long-term monitoring rarely undertaken.
