Improved human greenspace exposure equality during 21st century urbanization

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: Oct. 13, 2023

Greenspace plays a crucial role in urban ecosystems and has been recognized as key factor promoting sustainable healthy city development. Recent studies have revealed growing concern about greenspace exposure inequality; however, the extent to which urbanization affects human associated inequalities over time remains unclear. Here, we incorporate Landsat-based 30-meter time-series mapping population-weighted framework quantify changes equality (rather than equity) for 1028 global cities from 2000 2018. Results show substantial increase physical coverage an improvement greenspace, leading reduction inequality past two decades. Nevertheless, observe contrast rate of between Global South North, with faster South, nearly four times that North. These findings provide valuable insights into impact on nature environmental change can help inform future greening efforts.

Algorithmic green infrastructure optimisation: Review of artificial intelligence driven approaches for tackling climate change

Sustainable Cities and Society, Journal Year: 2024, Volume and Issue: 101, P. 105182 - 105182

Published: Jan. 7, 2024

Green infrastructure (GI) is a fundamental building block of our cities. It contributes to the sustainability and vitality cities by offering various benefits such as greening, cooling, water, air quality, managing carbon emissions. GI plays an essential role in enhancing overall well-being. The utilisation artificial intelligence (AI) technologies for optimisation perceived powerful approach A knowledge gap, nevertheless, remains research on AI-driven tackling climate change. This study aims consolidate comprehension optimisation, particularly methodology adopts PRISMA protocol perform systematic literature review. review results are analysed from six aspects—i.e., objectives, objectives categories, indicators, models, types, scales. findings revealed: (a) was mainly undertaken areas biodiversity ecosystem security, energy efficiency, public health, heat islands, water management; (b) Indicator categories were concentrated indicators related GI, objective, other general/supporting indicators. Based these findings, framework developed enhance understanding process within realm

Pathways to 15-Minute City adoption: Can our understanding of climate policies' acceptability explain the backlash towards x-minute city programs?

Cities, Journal Year: 2024, Volume and Issue: 148, P. 104878 - 104878

In recent months, 15-min city policies have faced significant backlash across social media, in opinion pieces, and even through street demonstrations, casting doubt on the future of x-minute as effective tools fight against climate change. The protests not only challenge implementation policies, but also highlight our lack understanding regarding which acceptability factors affect public reactance to this new kind urban policy. This paper reviews existing literature reveal four main shaping policy acceptability. It then juxtaposes these common criticisms leveled at model. comparative analysis illuminates limitations applying traditional frameworks context, identifies critical gaps literature. By bridging divide, we aid policymakers navigating spectrum skepticism model, from addressing debunking conspiracy theories engaging with scientifically-grounded critiques. Our findings offer a roadmap for transforming innovative planning concepts into widely embraced solutions change mitigation.

Global disparities in urban green space use during the COVID-19 pandemic from a systematic review

Nature Cities, Journal Year: 2024, Volume and Issue: 1(2), P. 136 - 149

Published: Jan. 18, 2024

Abstract The COVID-19 pandemic disrupted urban resilience and challenged the use of green space (UGS). Previous studies lack consensus on whether UGS increased or decreased during after lockdowns how this related to policy, economic conditions types. In a systematic review, we screened >3,000 articles in 5 languages, identifying 177 changes 60 countries. cities studied show diverging use. Generally, decreases occurred where policies were stricter gross domestic product per capita was lower, including most few areas Global South. All private gardens 60% forests other natural showed increases, while 77% conducted public parks indicated global disparity exacerbated pandemic, demonstrating need enhance infrastructure for healthy extend it beyond parks.

Environmental justice in a very green city: Spatial inequality in exposure to urban nature, air pollution and heat in Oslo, Norway

The Science of The Total Environment, Journal Year: 2022, Volume and Issue: 858, P. 160193 - 160193

Poorer citizens are often more exposed to environmental hazards due spatial inequalities in the distribution of urban blue-green space. Few cities have managed prevent and social inequality despite sustainable development strategies like compact city planning. We explore whether injustice exists a where one would least expect find it: with abundant nature, an affluent population governed by left leaning democratic council, aggressive densification strategy; Oslo, Norway. Green space was measured satellite-derived vegetation index which captures combined availability gardens, street trees, parks forest. Blue defined proximity residential areas closest lake, river or fjord. found that poorer districts, greater immigrant populations, less available spaces disproportionately hazardous air pollution levels, but not extreme heat compared wealthier districts. Citizens living within 100 m water body likely earn US$ 20,000 per year than 500 away from water, 3000 increase annual income corresponds 10 % green availability. Hazardous concentrations poorest districts were above levels recommended WHO Oslo municipality.

Abstract Heavily featured over the last few years in global research and policy agreements, Nature-Based Solutions (NBS) remain however exposed to much debate ways their current design ability achieve both environmental goals social needs. As they become mainstream climate mitigation adaptation options, capacity deliver expected benefits, especially when contemplating equity justice, is at least uncertain. Through a critical review of existing debates perspectives on NBS, this paper questions uptake points frequent embeddedness NBS speculative elite-based development paths urban rural areas. We present an alternative, justice-oriented approach so that projects can avoid nature-enable dispossession instead build nature-inspired justice prioritizes needs, identities, livelihoods most ecologically socially vulnerable residents.

Exploring green gentrification in 28 global North cities: the role of urban parks and other types of greenspaces

Environmental Research Letters, Journal Year: 2022, Volume and Issue: 17(10), P. 104035 - 104035

Abstract Although cities globally are increasingly mobilizing re-naturing projects to address diverse urban socio-environmental and health challenges, there is mounting evidence that these interventions may also be linked the phenomenon known as green gentrification. However, date empirical on relationship between greenspaces gentrification regarding associations with different greenspace types remains scarce. This study focused 28 mid-sized in North America Western Europe. We assessed improved access of (i.e. total area parks, gardens, nature preserves, recreational areas or greenways [i] added before 2000s [ii] 2010s) processes (including for 2000s; 2010s; [iii] throughout decades each small geographical unit city. To estimate associations, we developed a Bayesian hierarchical spatial model city time period maximum three models per city). More than half our showed parks—together other factors such proximity center—are positively associated processes, particularly US context, except historically Black disinvested postindustrial lots vacant land. find newly designated preserves negatively when considering 2010s US. Meanwhile, new spaces greenways, research shows mixed results (some positive, some negative no effect associations). Considering environmental benefits projects, should keep investing improving park while simultaneously implementing anti-displacement inclusive policies.
