2015 was a seismic moment for urban stakeholders around the world. A coalition of policymakers, academics and practitioners came together to successfully advocate for an urban goal to be included in the UN Sustainable Development Goal framework. Although the value of a place-based approach to development has been demonstrated by a number of cities and countries worldwide, it was 2020–2022 (three years of cataclysmic global events) that highlighted the necessity for a universal place-based approach to planning in order to foster resilience and sustainability. In this article, three academic-practitioners reflect upon the transformative potential of the 2015–16 urban agendas.

Urban dwellers’ use of public and private green spaces may have changed during the early years of the Covid-19 pandemic due to movement restriction. A survey was deployed in Brisbane and Sydney, Australia 1 year after the start of Covid-19 restrictions (April 2021) to explore relationships of mental health and wellbeing to different patterns of private yard versus public green space visitation. More frequent yard use during the initial year of Covid-19 was correlated with lower stress, depression, and anxiety and higher wellbeing. However, greater duration of yard visits (week prior to survey) was associated with higher stress, anxiety, and depression scores, potentially because individuals may seek to use nature spaces immediately available for emotional regulation during difficult times. The results highlight the importance of yards for mental health and wellbeing during the Covid-19 pandemic and that relationships between nature interaction and mental health may be context and timeframe dependent.

Defining and measuring progress in adaptation are important questions for climate adaptation science, policy, and practice. Here, we assess the progress of urban adaptation planning in 327 European cities between 2005 and 2020 using three ‘ADAptation plan Quality Assessment’ indices, called ADAQA-1/ 2/ 3, that combine six plan quality principles. Half of the cities have an adaptation plan and its quality significantly increased over time. However, generally, plan quality is still low in many cities. Participation and monitoring and evaluation are particularly weak aspects in urban adaptation policy, together with plan ‘consistency’. Consistency connects impacts and vulnerabilities with adaptation goals, planned measures, actions, monitoring and evaluation, and participation processes. Consistency is a key factor in the overall quality of plans. To help evaluate the quality of plans and policies and promote learning, we suggest incorporating our ADAptation plan Quality Assessment indices into the portfolio of adaptation progress assessments and tracking methodologies.

Green roofs affect the urban food-water-energy nexus and have the potential to contribute to sustainability. Here we developed a generalizable methodology and framework for data-sparse cities to analyze the food-water-energy nexus of green roofs. Our framework integrates the environmental costs and benefits of green roofs with food-water-energy systems and makes it possible to trace energy-water-carbon footprints across city boundaries. Testing the framework in São José dos Campos (SJC), Brazil and Johannesburg, South Africa, we found that green roofs are essentially carbon neutral and net energy consumers from a life cycle perspective. SJC is a net water beneficiary while Johannesburg is a net water consumer. Rainwater utilization could save irrigated water, but requires 1.2 times more energy consumption. Our results show that SJC and Johannesburg could direct their green roof development from local food production and energy saving, respectively and highlight opportunities for green roof practices in cities.

Due to rapid urbanisation, food systems in sub-Saharan African cities are increasingly under pressure. Through the lens of a foodshed, this paper quantitatively analyses the spatial extent of the food provisioning area for consumers of different socio-economic status in Kampala (Uganda). Based on a primary dataset of surveys with households and food vendors, we map the foodshed by registering where consumers obtain their food, and the origin of where it is grown. We show that 50% of the food consumed in the city originates from within a 120 km proximity to Kampala, including 10% from within the city itself. At present, urban agricultural activities are twice as important as international imports for the urban food provision. Established, high-income urban dwellers have a more local foodshed due to their broad participation in urban agriculture, while low-income newcomers rely heavily on retailers who source food from rural Uganda.

Introducing nature based solutions (NBS) into urban areas is a challenging task for climate change mitigation and adaptation. However, the impact and effectiveness of NBS contingent upon the social acceptability of implemented measures. This study uses a dynamic and adaptive social acceptance framework that shows how data-driven science can inform the integration of NBS into cities while also ensuring that the public embraces these solutions. We apply the framework to four different cases: METU Forest in Ankara, Tisza River Bank in Szeged, Forest Garden in Alcalá de Henares, and Quarries in Milan. The results indicate that the key factor affecting social acceptance are procedural and distributive fairness, perceived risks, costs and benefits, knowledge, experience, and personal norms. Perceived benefit is the single common driver that directly affects social acceptance across the four case studies. Understanding the risk and benefits of an NBS and developing personal norms related to the environment will contribute to the improvement of resilience.
在城市地区引入基于自然的解决方案（NBS）是减缓和适应气候变化的一项具有挑战性的任务。然而，NBS 的影响和有效性取决于社会对所实施措施的接受程度。本研究采用了一个动态和适应性的社会接受度框架，该框架展示了数据驱动的科学如何在确保公众接受这些解决方案的同时，为将基于自然的解决方案纳入城市提供信息。我们将该框架应用于四个不同的案例：安卡拉的 METU 森林、塞格德的 Tisza 河岸、阿尔卡拉德埃纳雷斯的森林花园和米兰的采石场。结果表明，影响社会接受度的关键因素是程序和分配公平性、感知风险、成本和收益、知识、经验和个人规范。在四个案例研究中，感知收益是直接影响社会接受度的唯一共同驱动因素。了解非核心预算系统的风险和益处，并制定与环境相关的个人规范，将有助于提高抗灾能力。

The introduction of vehicle automation, shared mobility, and vehicle electrification will bring about changes in urban transportation, land use, energy, and the environment. The accurate estimation of these effects is therefore essential for sustainable urban development. However, existing research on estimating the energy and environmental effects of shared autonomous electric vehicles generally ignores the interaction between land-use and transportation systems. This study, therefore, analyzes the long-term effects of shared autonomous vehicles (SAVs) from the perspective of land use and transportation integration. Different SAV pricing scenarios are also developed to explore the optimal pricing strategy for low carbon–oriented SAVs. Moreover, the study has further assessed the effect of vehicle electrification on vehicle emissions and energy consumption. The results have shown a nonlinear relationship between SAV fares and their transportation, land-use, energy, and environmental effects. Under an appropriate pricing strategy, SAV deployment could reduce PM2.5 emission and energy consumption by 56–64% and 53–61%, respectively. With the further introduction of vehicle electrification, these can rise to 76% and 74%.

Human development is a complex process involving interactions between individuals and their socioeconomic, biological, and physical environments. It has been studied using two frameworks: the “Capabilities Approach,” implemented at the national scale, and the “Neighborhood Effects Approach,” implemented at the community scale. However, no existing framework conceptualizes and measures human development across geographic scales. Here, we unite the two approaches by localizing the Human Development Index (HDI), and demonstrate a methodology for scalable implementation of this index for comparative analysis. We analyzed patterns of development in the United States, characterizing over 70,000 communities. We found that, on average, larger cities have higher HDI (higher standard of living) but exhibit greater disparities between communities, and that increases in community HDI are associated with the simultaneous reduction of a diverse set of negative neighborhood effects. Our framework produces an interdisciplinary synthesis of theory and practice for sustainable, equitable urban health and development.

We use a globally consistent, time-resolved data set of CO2 emission proxies to quantify urban CO2 emissions in 91 cities. We decompose emission trends into contributions from changes in urban extent, population density and per capita emission. We find that urban CO2 emissions are increasing everywhere but that the dominant contributors differ according to development level. A cluster analysis of factors shows that developing countries were dominated by cities with the rapid area and per capita CO2 emissions increases. Cities in the developed world, by contrast, show slow area and per capita CO2 emissions growth. China is an important intermediate case with rapid urban area growth combined with slower per capita CO2 emissions growth. Urban per capita emissions are often lower than their national average for many developed countries, suggesting that urbanisation may reduce overall emissions. However, trends in per capita urban emissions are higher than their national equivalent almost everywhere, suggesting that urbanisation will become a more serious problem in the future. An important exception is China, whose per capita urban emissions are growing more slowly than the national value. We also see a negative correlation between trends in population density and per capita CO2 emissions, highlighting a strong role for densification as a tool to reduce CO2 emissions.
