Urban areas encompass essential social functions that are fundamental for the development and quality of life. This research explores why concept 15-minute city, while commendable in its aspirations, might fall short effectively mitigating urban inequalities, especially within densely populated segregated developing cities. Using Bogotá (Colombia) as a case study, this paper advocates develops standardized index based on availability walking distance. also integrates individual preferences, geographical attributes, pedestrian infrastructure. Doing so provides more comprehensive understanding factors influencing proximity, accommodating diverse needs various identities. Considering preferences towards proximity is critical to comprehend determinants accessibility, encompassing relevance sociodemographic characteristics. Although several worldwide may meet broad interpretation city concept, our reveals significant disparities among population segments regarding access services their prioritization. Our study found grocery stores healthcare facilities hold paramount importance across all segments. Furthermore, wealthy exhibit heightened preference retail shops commercial services. In contrast, low-income has considerably greater facilities. aims cast light upon structural inherent areas, thereby unveiling inequalities concept's capacity diagnose mitigate inequalities. The promotion all-encompassing inclusive measurement approach posited contribution advancement comprehension effective implementation heterogeneous landscapes.

The pandemic and the environmental crisis raise question of a radical transformation cities to foster inclusion, sustainability, participation, quality life. 15-minute city concept prefigures reorganization urban spaces, structures, functions aimed at increasing residents' access essential services, favoring sustainable modes transportation, transforming public spaces into multifunctional places. proposed study develops set indicators derived from spatial configurational analysis evaluate compliance systems with concept. selected areas are Cagliari, Perugia, Pisa, Trieste, in Italy. investigates four issues: i) defining relevant, reproducible, comparable for measuring density, proximity, diversity; ii) investigating influence distinct planning concepts, manifested by configurations, on iii) scale metrics measure levels injustice terms unequal conditions services iv) correlation between factors services. underlines gap among central compact districts dispersed outer areas, thus enabling identification inequalities distribution capital. Moreover, relationship environment structure location functions. As result, emphasizes that is instrumental understanding environment's potential meet populations' needs facilitating informed decisions planning.

A systematic review of the 15-minute city framework: implications for environmental heritage preservation in the Anthropocene

International Journal of Urban Sciences, Год журнала: 2025, Номер unknown, С. 1 - 30

Опубликована: Янв. 1, 2025

The 15-minute city model proposes a transformative urban planning framework aimed at reducing car dependency, enhancing accessibility, and promoting sustainability. Despite its alignment with the United Nations Sustainable Development Goals (UN SDGs), empirical quantitative validations of environmental benefits remain scarce. This study employs hybrid methodology that combines systematic literature review, topic modelling, sentiment analysis to examine capacity mitigate challenges. review identified three main thematic areas in literature: (1) decarbonization impacts, (2) sustainability resilience, (3) accessibility. While has been widely discussed, only 10.2% focuses on outcomes, revealing significant research gap. Topic modelling further uncovers five core themes mostly related mobility, where critical terms like 'emissions', 'sustainability', 'decarbonization' are notably absent, reinforcing lack focus model's ecological contributions. Sentiment reveals cautiously optimistic tone scholarly discourse, researchers recognizing theoretical promise but expressing reservations about real-world efficacy addressing climate change. Therefore, this highlights urgent need for context-specific investigations quantify city's contribution emissions resilience long term. provides data-driven insights guide policymakers planners making informed decisions regarding sustainable development Anthropocene epoch.

Conventional and emerging paradigms of urbanism require new responses under the current circumstances, especially in relation to integration sustainability dimensions technology advances. The escalating rate urbanization, coupled with climate emergency, fundamentally indeed disrupt challenges that research practice deal with, calling for adopting more innovative approaches urban planning design. With cities contributing around 65% Greenhouse Gas (GHG) emissions experiencing an unprecedented growth population, contemporary policy needs be redefined re-assessed accordingly. While numerous models, such as Compact City, Eco-City, Sustainable Smart have emerged response 15-Minute City has recently gained a steep popularity. This paper explores theoretical, practical, technological foundations particular focus on proximity dimension mixed land-use its environmental, social, economic benefits supported by smart technologies. We argue this evolving model potential gain expansion success regard building sustainable, efficient, resilient, equitable, inclusive line global agendas Development Goal (SDG) 11, it adds strategic value amalgam prevailing their synergies respect increasing while emphasizing environmental dimension.

Rapid rise in urban sprawl: Global hotspots and trends since 1990

Dispersed low-density development–“urban sprawl”–has many detrimental environmental, economic, and social consequences. Sprawl leads to higher greenhouse-gas emissions poses an increasing threat the long-term availability of vital ecosystem services. Therefore, urban sprawl is in stark contradiction principles sustainable land use need for a sustainability transformation. This study presents degree on planet at multiple spatial scales (continents, UN regions, countries, subnational units, regular grid) period 1990–2014. Urban increased by 95% 24 years, almost 4% per year, with built-up areas growing 28 km 2 day, or 1.16 hour. The results demonstrate that Europe has been most sprawled also rapidly sprawling continent, 51% since 1990.

A composite X-minute city cycling accessibility metric and its role in assessing spatial and socioeconomic inequalities – A case study in Utrecht, the Netherlands

Journal of Urban Mobility, Год журнала: 2022, Номер 3, С. 100043 - 100043

Опубликована: Дек. 28, 2022

The 15 min city (or "X-minute city" in general) concept aims to give people access all essential services and daily needs (e.g., healthcare, education, etc.) within X minutes of active transportation, improve transport equity, sustainability, traffic safety. To date, there is a lack methods tools assess what degree cities currently, or after implementing policies, comply with the X-minute concept. This research develop methodology for quantifying through metric (CSx) that was developed based on an accessibility framework tested cycling mode Utrecht region Netherlands as study area. Travel data from mobility panel were analysed determine input characteristics metric, such weight destination types. Standardized gravity-based 2-step floating catchment area (2SFCA) scores types weighted aggregated into composite shows relative city. results analysis show 100% population has at least one 9 min, whereas this number reduces 94% 10 threshold; indicating status cycling-friendly infrastructure. Furthermore, low-income groups do not have lower area, reinforcing notion can be effective solution reduce inequalities. used their way towards becoming city, prioritise neighbourhoods develop, set quantifiable goals, evaluate planning scenarios.
