Sustainable cities and human settlements

The United Nations Sustainable Development Goal (SDG) 11 aims to "Make cities and human settlements inclusive, safe, resilient, and sustainable." This goal acknowledges the growing importance of urban areas, as it's projected that by 2050, nearly 70% of the world's population will live in cities. Consequently, cities bear significant implications for sustainability, economic growth, and societal wellbeing.

Inclusivity is a key feature of sustainable cities. This refers to equitable access to opportunities, public services, and amenities, regardless of a person's background or circumstances. It implies the availability of affordable and adequate housing, thus addressing issues of homelessness and substandard living conditions.

Safety in cities means ensuring urban environments that protect their inhabitants from both physical harm and psychological distress. This involves addressing crime rates, traffic accidents, and potential hazards from poor infrastructure, while also considering the impacts of noise, pollution, and overcrowdedness on mental health.

Resilience is another important aspect, particularly in the face of climate change. Resilient cities can withstand and quickly recover from shocks such as natural disasters or economic crises. This involves aspects such as resilient infrastructure, disaster risk reduction strategies, and adaptive capacities at the community level.

Sustainability, finally, requires cities to function in a way that doesn't compromise future generations' ability to meet their own needs. This includes sustainable urban planning to reduce environmental impact, promote energy efficiency, and conserve resources. It also considers the importance of green spaces for biodiversity and the wellbeing of urban residents.

SDG 11 is interconnected with many other SDGs. For example, sustainable urban transport systems contribute to SDG 13 (Climate Action) by reducing greenhouse gas emissions. Meanwhile, ensuring access to green and public spaces supports SDG 3 (Good Health and Well-being).

Achieving sustainable cities and human settlements requires cooperation and participation from various stakeholders, including government authorities, urban planners, businesses, and citizens. Through their collective efforts, cities can be transformed into hubs of sustainability, resilience, and inclusivity, contributing significantly towards the realization of the SDGs.

The editorial calls for action to reduce noise pollution that has detrimental impact on humans, terrestrial and marine life
The study concludes that power outages disproportionately impact urbanized areas and highlights the intersectionality of health risks and urban resilience, pertinent to both Sustainable Development Goal 3 (Good Health and Well-being) and SDG 11 (Sustainable Cities and Communities).
Using Health personal protective equipment (PPE) such as face masks, safety foot shoes and protective suits has expanded dramatically due to COVID-19 pandemic leading to a widespread distribution of the PPE, particularly the face masks, in the environments including streets, dump sites, seashores and other risky locations. The environmental degradation of polypropylene, the essential plastic component in single-use face masks (SUM), takes between 20 and 30 years and thus it is essential to develop experimental approaches to recycle the polypropylene or to reuse it in different ways.
This chapter aligns with SDG Goal 11: Sustainable cities and communities by discussing how smart technologies have the potential to make cities safer and more inclusive for women and gender-diverse people.

Resilient and Sustainable Cities: Research, Policy and Practice, 2022, Pages 519-535

This chapter advances the UN SDG goals 11, 12, and 13 by offering two alternate approaches to Western planning—city making informed by biophilic systems and First Nations values—through Australian case studies that have similar systems of thought, aspirations, and values. The challenge is for use to adapt (or retrofit) our cities to redress climate change and our consumption values toward crafting robust, resilient, respectful and sustainable places.
