Cities worldwide are facing a significant threat of stormwater hazards caused by the increase in extreme downpours and urbanization. Meso-level urban management focuses on alleviating detrimental impacts flooding enhancing water resource utilization at block or community scale, typically through 1) specific policies rules; 2) catchment-scale scenario simulation, optimization evaluation; 3) group control measures implementation. It may effectively coordinate macro-level planning micro-level distributed facilities.

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.

Ecosystem services are essential for cities and key factors in achieving many of the Sustainable Development Goals (SDGs). Such best delivered through green infrastructure, which works resourceful, multifunctional, synergistic, environmentally sensitive ways to deliver ecosystem provide alternative cleaner pathways delivery multiple urban services. It is unclear if current research supports necessary linkages between services, cities, infrastructure order achieve SDGs. To answer this question, we conducted a systematic review analysing 3392 studies on SDGs from WoS database. The contents 66 those with relevance were reviewed depth. We applied network-analytic methods map relationships different knowledge clusters (1) across time, (2) disciplines, (3) relation cities. results our analysis show that have developed stronger networks 2010–2018, but has not been sustained. Further, whilst now occupies central place literature, only shows tentative links both green-infrastructure research. literature remains peripheral challenge sustainable transitions. conclude when it comes SDGs, articles typically consider independently infrastructure. suggests generally considered as conventional infrastructures. address serious shortcoming, recommend transdisciplinary approaches link 2030 global sustainability agenda.

Low-regret climate change adaptation in coastal megacities – evaluating large-scale flood protection and small-scale rainwater detention measures for Ho Chi Minh City, Vietnam

Natural hazards and earth system sciences, Journal Year: 2023, Volume and Issue: 23(6), P. 2333 - 2347

Abstract. Urban flooding is a major challenge for many megacities in low-elevation coastal zones (LECZs), especially Southeast Asia. In these regions, the effects of environmental stressors overlap with rapid urbanization, which significantly aggravates hazard potential. Ho Chi Minh City (HCMC) southern Vietnam prime example this set problems and therefore suitable case study to apply concept low-regret disaster risk adaptation as defined by Intergovernmental Panel on Climate Change (IPCC). order explore evaluate potential options mitigation, hydro-numerical model was employed scrutinize effectiveness two strategies: (1) classic flood protection scheme including large-scale ring dike currently constructed HCMC (2) widespread installation small-scale rainwater detention envisioned framework Chinese Sponge Program (SCP). A third scenario (3) assesses combination both approaches (2). From hydrological point view, reduction various intensity proxies that were computed within suggests comparable but slightly more effective than storage: instance, could reduce normalized severity index (INFS), measure combining depth duration, 17.9 % 17.7 %, respectively. The number flood-prone manufacturing firms would be protected after adaptation, turn, nearly 2 times higher approach. However, numerical results also reveal response can implemented parallel, not only without reducing their individual complementarily considerable added value. Additionally, from governance perspective, decentralized storage conforms ideally paradigm: while existing depends binary commitment (to build or build), small- micro-scale solutions gradually (for through targeted subsidies) add technical redundancy overall system. end, strategies are highly complementary spatial temporal intensity. Local decision-makers may hence specifically seek combined strategies, adding singular approaches, design multi-faceted pathways successfully prepare deeply uncertain future.

Nature-based Solutions (NbS) are becoming a promising tool to tackle various challenges in global and Chinese contexts. However, the overall progress of NbS implementation China has not been thoroughly investigated, existing studies questioned whether can be truly effective consideration an incomplete policy system prevailing centralized decision-making. By summarizing policies practices falling under concept comparing them with globally recognized lessons, this paper concludes that achieved prominent practice on climate mitigation, biodiversity conservation, water security, sustainable cities. The comparison between globe reveals gained strengths terms context-based design, planning beyond administrative borders, adaptive monitoring methods, financing innovative technology facilitation, community livelihood diversification. As recommendations for domestic policymakers practitioners, article also points potential pathways upscaling especially by creating systematically unified system. For future research, more empirical needed explore how different extents decision-making transparency engagement affect actual outcome practices.

Nature-Based Solutions, Journal Year: 2024, Volume and Issue: 5, P. 100115 - 100115

Published: Feb. 15, 2024

Urban floods induced by the compound effects of climate change and rapid urbanisation are one key challenges facing many Chinese cities. In 2013, China initiated Sponge City Program (SCP) to address this issue via constructing/restoring green-blue infrastructure as Nature-Based Solutions (NBS). Various green blue spaces have been integrated into traditional grey facilities mitigate urban floods, provide recreational venues, enhance natural aesthetics landscapes. While housing development has actively included in NBS provision, it remains unclear whether how homebuying decisions might be influenced implementation under framework Program. Our study uses Guiyang, pilots selected central government for construction "Sponge City" implementing NBS. In-depth semi-structured interviews (n=25) were used examine multiple benefits generated newly established (sponge) would affect residents' home-purchasing preferences/decisions. We found that provision a facility, is part SCP or not, significantly influences homebuyers' choice. This sheds additional light on nexus end users (homebuyers) (developers) Program, generating practical implications stakeholder engagement achieve sustainable urbanization.
