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.

It is no secret to anyone living in Beirut or a similar modern city in a semi-arid tropical country in the summer that their home has become a concrete forest and an urban heat island. Old wood or stone houses and their gardens have been replaced by concrete towers and parking lots, in the name of development. The result is searing summer nights, a drastic loss of insect and avian biodiversity, and a large increase in energy usage for interior climate control. These problems are experienced in rapidly developing urban centers worldwide.
Urban water and energy systems are crucial for sustainably meeting basic service demands in cities. This paper proposes and applies a technology-independent “reference resource-to-service system” framework for concurrent evaluation of urban water and energy system interventions and their ‘nexus’ or ‘interlinkages’. In a concrete application, data that approximate New York City conditions are used to evaluate a limited set of interventions in the residential sector, spanning from low-flow toilet shifts to extensive green roof installations.

International Water Summit 2017, 16-19 January 2017

The International Water Summit (IWS) is a global platform for promoting water sustainability in arid regions by bringing together world leaders, field experts, academics and business innovators to accelerate the development of new sustainable strategies and technologies. Videos from the 2017 summit cover a wide range of technologies and innovations which support SDG 6 Clean Water and Sanitation and SDG 11 Sustainable Cities and Communities.

Urbanization is transforming human society in many ways. Besides all the obvious benefits, it also brings negative impacts such as the well-documented urban heat island (UHI) effect and the magnified human heat stress. One way to reduce human heat stress is to increase vegetation density in urban areas, because they can provide evatranspiration and shading benefits. However, given the diversity of tree species and their morphological properties, it is important to understand rationally how different trees regulate thermal comfort.

This collection of articles from the Editors of Environment International Journal explore the impact of climate change on health. The collection demonstrates the interconnectedness of SDG 13 and SDG 3. Understanding the changes and associated impact allows us to develop appropriate adaptive policies and practices to respond to climate-sensitive health risks.

All-Energy, 10-11 May 2017

All-Energy
All-Energy is the UK’s largest renewable energy event, providing industry suppliers and thought-leaders the opportunity to connect with new customers and expand business networks in this fast-changing marketplace as well as learn about latest technologies and solutions. Presentations from the 2017 event provide invaluable insights into bioenergy, solar, offshore and onshore wind, hydropower and wave & tidal sectors, as well as energy storage, low carbon transport and sustainable cities solutions. This is directly related to SDG 7: Affordable and clean energy.

Growing media (substrate) is a fundamental part of a green roof, providing water, nutrients and support to plants. However, little research has reviewed how it affects plant performances in different climatic regions. This study aims to analyse published research on green roof growing medium across world's climate zones. Findings are structured according to Köppen–Geiger climate classification, aiming to investigate the prevalence of research conducted in different climate zones. Results from full-scale studies and laboratory or greenhouse experiments were reviewed.

This article aims to contribute to current discussions about “making cities inclusive, safe, resilient, and sustainable” (SDG 11) by linking debates that are currently taking place in separate containers: debates on the “global land rush” and the “new urban agenda”. It highlights some important processes that are overlooked in these debates and advances a new, socially inclusive urbanization agenda that addresses emerging urban land grabs.

A number of property companies are going beyond traditional corporate responsibility to be net positive. Instead of opting for sustainability strategies that manage risk and reduce negative impacts, these companies are seeking to put back more into society, the environment and the global economy than they take out. Whilst the breadth and scope of these net positive commitments made by real estate leaders vary, there is enormous opportunity for this sector with sustainability and in supporting SDG 7 and 13.
Assuming communities in a city may formally express their aspirations for the future sustainability of their city, which technological innovations for changing the city's infrastructure and metabolism might they introduce today, as a first step towards realizing their distant aspirations? What is more, recognizing the diversity of aspirations that may never be reconciled into a consensus, might some innovations and policy interventions be nevertheless more privileged than others, in being non-foreclosing? How might we discover this?
