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.

This study presents a critical review analysis of greenery systems research through a bibliometric approach. The purpose of this study is to provide a holistic overview by (i) the development of the field; (ii) the research trends and the main issues; and (iii) the main gaps still observed in the literature. Therefore, this paper provides the past, the present and the potential future of this scientific topic and serves as an orientation and guide for researchers who aim for a better understanding of the main progress and gaps.
Building and Environment will host a series of free webinars on COVID-19 Control. The second webinar of the series will feature 2 presentations from experts in the field on the following topics: COVID-19 and indoor and outdoor sports, presented by Bert Blocken, Professor of Civil Engineering, Eindhoven University of Technology, the Netherlands & KU Leuven, Belgium. Efficient reduction of airborne transmission by advanced ventilation, presented by Arsen K. Melikov, Professor of Ventilation and Air Distribution, Technical University of Denmark, Denmark.

These are uncertain times in the Anthropocene, where the health and resilience of all urban inhabitants should be key themes for cities striving for sustainability. To this end, local councils in Australia are applying digital technologies with increasing complexity as components of their urban forest management. This paper applies a more-than-human lens to analyse Australian local council urban forest policies, documents and project information for their inclusion and application of digital technologies.

Buildings consume vast amounts of energy and pollute the environment in various ways. Façade is a part of building's architecture that can play a significant role in reducing energy consumption, as well as alleviating its negative environmental effects. Although using smart materials in buildings' facades can help dramatically to attain the mentioned goals, very limited studies have been conducted regarding the mentioned issues. Moreover, existing studies have investigated only a few number of smart materials simultaneously.

Food waste valorization is a hot topic due to the cornucopia of waste generated and the ensuing detrimental environmental effects. Food is lost or wasted in a variety of means on its way from field to mouth. Once deemed inedible, it is considered a waste, but it still contains first-rate organic material that can be processed and used to create a host of new products, chemicals, or energy. Upgrading food wastes can be performed in a variety of processes.
Deterioration of water quality due to economic development, climate change and other factors has become a challenge to human beings and the ecosystem. Most countries have recognized this problem and have resorted to actions for improving water quality. However, the effect on water quality improvements due to these actions is uncertain due to the plausibility of multiple scenarios like climate change scenarios and socio- economic scenarios.
This paper assesses the influence of land development patterns on intra-urban thermal variation in a densely-developed subtropical city, considering joint effect from greenspace pattern and built-up geometry. Despite growing research on urban climates, research at a scale that can support urban planning with scientificallyinformed strategies is still not as well documented for warm climate cities as for temperate cities. In response, this paper uses land surface temperature and geoinformation to assess the subtropical city of Taipei, Taiwan.
This book chapter advances SDGs 6, 12 and 11 by analyzing research studies on water remediation within the framework of 12 principles of green chemistry, bibliometric features, and characteristics of related research papers.
This book chapter advances SDGs 15 and 11 by exploring a holistic approach to urban soil restoration which seeks to improve urban soils using integrated socioecological and landscape-scale approaches that embrace diverse outcomes including novel ecosystems and many sociocultural goals.
This book chapter advances SDGs 15 and 11 by reviewing the anthropogenic activities worldwide that have caused ecological degradation resulting in the need to mitigate damage to essential ecosystem services in rural and urban areas.
