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

A growing number of Nature-based Solutions (NbS) has been advocated for urban flood risk management (FRM). However, whether NbS for FRM (NbS-FRM) achieves both social and ecological co-benefits remains largely unknown. We here propose and use a conceptual framework with a coupled social-ecological perspective to explore and identify such “win-win” potential in NbS-FRM. Through a scoping-review we find that ecological FRM measures are unevenly distributed around the world, and those solely targeting flood mitigation may have unintended negative consequences for society and ecosystems. In elaborating this framework with evidence from the reviewed studies, we find that NbS-FRM has the potential to provide both social and ecological co-benefits, with remaining gaps including a lack of resilience thinking, inadequate consideration of environmental changes, and limited collaborative efforts to manage trade-offs. The proposed framework shows how to move forward to leverage NbS for equitable and sustainable FRM with improved human well-being and ecosystem health.

Excessive heat is a major and growing risk for urban residents. Here, we estimate the inequality in summertime heat-related mortality, morbidity, and electricity consumption across 5723 US municipalities and other places, housing 180 million people during the 2020 census. On average, trees in majority non-Hispanic white neighborhoods cool the air by 0.19 ± 0.05 °C more than in POC neighborhoods, leading annually to trees in white neighborhoods helping prevent 190 ± 139 more deaths, 30,131 ± 10,406 more doctors’ visits, and 1.4 ± 0.5 terawatt-hours (TWhr) more electricity consumption than in POC neighborhoods. We estimate that an ambitious reforestation program would require 1.2 billion trees and reduce population-weighted average summer temperatures by an additional 0.38 ± 0.01 °C. This temperature reduction would reduce annual heat-related mortality by an additional 464 ± 89 people, annual heat-related morbidity by 80,785 ± 6110 cases, and annual electricity consumption by 4.3 ± 0.2 TWhr, while increasing annual carbon sequestration in trees by 23.7 ± 1.2 MtCO2e yr−1 and decreasing annual electricity-related GHG emissions by 2.1 ± 0.2 MtCO2e yr−1. The total economic value of these benefits, including the value of carbon sequestration and avoided emissions, would be USD 9.6 ± 0.5 billion, although in many neighborhoods the cost of planting and maintaining trees to achieve this increased tree cover would exceed these benefits. The exception is areas that currently have less tree cover, often the majority POC, which tend to have a relatively high return on investment from tree planting.

The global energy demand has greatly impacted greenhouse gas emissions and climate change. Since buildings are responsible for a large portion of global energy consumption, this study investigates the energy-saving potential of green roofs and cool roofs in reducing building energy consumption. Using an integrated approach that combines climate change modeling and building energy simulation, the study evaluates these strategies in six global cities (Cairo, Hong Kong, Seoul, London, Los Angeles, and Sao Paulo) under current and future climate change scenarios. The results show that in future climates, the implementation of green and cool roofs at the city level can lead to substantial annual energy reductions, with up to 65.51% and 71.72% reduction in HVAC consumption, respectively, by 2100. These findings can guide the implementation of these strategies in different climatic zones worldwide, informing the selection and design of suitable roof mitigation strategies for specific urban contexts.

We present the Urban Nature Indexes (UNI), a comprehensive tool that measures urban ecological performance under one standard framework linked to global commitments. The UNI was developed by interdisciplinary experts and evaluated by practitioners from diverse cities to capture each city’s ecological footprint from local to global scale. The UNI comprises six themes (consumption drivers, human pressures, habitat status, species status, nature’s contributions to people, and governance responses) that encompass measurable impacts on climate change, biodiversity loss, ecosystem services, pollution, consumption, water management, and equity within one comprehensive system. Cities then adapt the UNI to their context and capacity by selecting among indicator topics within each theme. This adaptability and holistic approach position the UNI as an essential instrument for nature-positive transformations. With the institutional support of IUCN, the UNI offers an opportunity for cities to assess and enhance their contributions towards a more sustainable and biodiverse future.
我们介绍了城市自然指数 (UNI)，这是一种在与全球承诺相关联的标准框架下衡量城市生态绩效的综合工具。UNI 由跨学科专家开发，并由来自不同城市的实践者进行评估，以捕捉每个城市从本地到全球范围内的生态足迹。UNI 包括六个主题（消费驱动因素、人类压力、栖息地状况、物种状况、自然对人类的贡献以及治理对策），在一个综合系统中涵盖了对气候变化、生物多样性丧失、生态系统服务、污染、消费、水资源管理和公平的可测量影响。然后，城市通过在每个主题中选择指标主题，使 UNI 适应其环境和能力。这种适应性和整体性使 UNI 成为实现积极自然变革的重要工具。在世界自然保护联盟的机构支持下，UNI 为城市提供了一个机会，以评估和加强其对更可持续和生物多样性未来的贡献。

The present study investigates urban poverty in Seoul, South Korea, amid the COVID-19 pandemic, focusing on housing and economic challenges. Employing principal component analysis, clustering algorithms, and visualization techniques, it analyzes archived data to uncover disparities in housing conditions and economic well-being across Seoul. The research reveals significant socio-economic divisions, with over 75% of the city’s areas marked by vulnerability, indicating widespread poverty or the concentration of economically disadvantaged populations. This highlights the pervasive nature of poverty and the precarious situation of the urban poor, who are at risk due to fragile living conditions. The findings advocate for inclusive urban development strategies that prioritize the needs of marginalized groups, suggesting a shift from focusing solely on economic growth to ensuring equitable welfare for all residents.

Deprived urban areas, commonly referred to as ‘slums,’ are the consequence of unprecedented urbanisation. Previous studies have highlighted the potential of Artificial Intelligence (AI) and Earth Observation (EO) in capturing physical aspects of urban deprivation. However, little research has explored AI’s ability to predict how locals perceive deprivation. This research aims to develop a method to predict citizens’ perception of deprivation using satellite imagery, citizen science, and AI. A deprivation perception score was computed from slum-citizens’ votes. Then, AI was used to model this score, and results indicate that it can effectively predict perception, with deep learning outperforming conventional machine learning. By leveraging AI and EO, policymakers can comprehend the underlying patterns of urban deprivation, enabling targeted interventions based on citizens’ needs. As over a quarter of the global urban population resides in slums, this tool can help prioritise citizens’ requirements, providing evidence for implementing urban upgrading policies aligned with SDG-11.

Extreme heat events caused by continuous anthropogenic climate change have been increasing. Establishing public cooling environments (PCEs) is imperative for protecting public health and enhancing productivity. Yet, disparities in access to PCEs based on race, travel behavior, and income status can undermine their role in helping communities cope with extreme heat. This study investigates the varied access to three types of PCEs across 40 U.S. counties. Our findings reveal that White people enjoy greater access to PCEs than other groups, especially to tree-covered green spaces (TCGSs), outperforming Black people approximately three times. Driving can disproportionately narrow the racial/ethnic inequality gap compared to walking. Non-expense-required public environments (NERPEs) and expense-required public environments (ERPEs) are less accessible to high-income groups. Our research underscores the ongoing challenges in achieving environmental justice through equitable PCE access and stresses the importance of further studies and policy actions to eliminate disparities.

Researchers and city practitioners are paramount stakeholders in creating urban resilience but have diverse and potentially competing views. To understand varying stakeholder perspectives, we conducted a systematic literature content analysis on green infrastructure (GI) and reflective pavement (RP). The analysis shows a United States (US)-based science-practice disconnect in written communication, potentially hindering holistic decision-making. We identified 191 GI and 93 RP impacts, categorized into co-benefits, trade-offs, disservices, or neutral. Impacts were further classified as environmental, social, or economic. The analysis demonstrates that US city practitioners emphasize social and economic co-benefits that may not be fully represented in the scientific discourse. Scientists communicate a broader range of impacts, including trade-offs and disservices, highlighting a nuanced understanding of the potential consequences. Identifying contrasting perspectives and integrating knowledge from various agents is critical in urban climate governance. Our findings facilitate bridging the science-policy disconnect in the US heat mitigation literature.
