 Towards Sustainable Cities and Society: Addressing the Water Security Challenge

This special issues addresses the water security challenges critical to achieve sustainable cities and therefore advancing SDG 6 clean water and sanitation and SDG 11.

Increases in water treatment technology have made water recycling a viable engineering solution to water supply limitations. In spite of this, such water recycling schemes have often been halted by lack of public acceptance. Previous studies have captured the public's attitudes regarding planned reuse schemes, but here we focus on unplanned reuse (i.e. de facto reuse), present in many cities across the U.S.

The study of resilience in the face of large physical and climatic change has emerged as an important area of research. But while the physical variables under study are easily identified, the notion of resilience itself remains nebulous. In recent years, it has been taken to mean both mitigation and adaptation, concepts that are often used in interchangeably or in conjunction (sometimes hyphenated as “adaptation-mitigation”).

Shortages of freshwater have become a serious issue in many regions around the world, partly due to rapid urbanisation and climate change. Sustainable city development should consider minimising water use by people living in cities and urban areas. The purpose of this paper is to improve our understanding of water-use behaviour and to reliably predict water use. We collected appropriate data of daily water use, meteorological parameters, and socioeconomic factors for the City of Brossard in Quebec, Canada, and analysed these data using multiple regression techniques.

The detection of pharmaceuticals and endocrine disrupting compounds (EDCs), known as emerging contaminants (ECs), in the environment has attracted growing concern due to their toxicity and potential hazard to the ecosystems and humans. These contaminants are consumed at high quantities worldwide and they are released deliberately or accidentally into the water resources. The conventional treatment technologies that use biological processes cannot effectively remove these contaminants.

This paper uses ‘Medieval’ drought conditions from the 12th Century to simulate the implications of severe and persistent drought for the future of water resource management in metropolitan Phoenix, one of the largest and fastest growing urban areas in the southwestern USA. WaterSim 5, an anticipatory water policy and planning model, was used to explore groundwater sustainability outcomes for mega-drought conditions across a range of policies, including population growth management, water conservation, water banking, direct reuse of RO reclaimed water, and water augmentation.

Water harvesting is an ancient practice that has been used, mainly in dry environments, to increase efficiency of water collection and use by directing water from a large natural watershed or man-made collection surface into a small basin where the water can be stored in underground reservoirs or to be used directly for irrigation or domestic uses. In modern era water harvesting has been neglected, particularly at the developed countries, due to the technological achievements in the fields of water production and transport.

London's ability to remain a world-leading city in an increasingly globalised economy is dependent on it being an efficient, low-risk place to do business and a desirable place to live. However, increasing climate risk from flooding, overheating and water scarcity threatens this, creating the need for adaptation. An adaption pathway describes a structured sequence of adaptation decisions that are designed to manage climate risk in a wide range of possible future conditions.

This study sought to assess the relationship between regulatory and educational approaches to nutrient management and homeowner behaviors, perceptions, and knowledge of best management practices (BMPs). Fertilizers, and pesticides applied in excess by homeowners and landscapers can impair stormwater ponds and cause nuisance algae blooms, eutrophication and fish kills. They can also affect water quality in downstream creeks, and bays.

Water reuse networks have been emerging globally for the last 50 years. This article reviews the economic, social and environmental issues related to implementing water reuse networks in cities. This is reflecting the fact that globally many cities are categorised as water scarce areas, where there is growing imbalance between water demand and availability. In this sense, there is a need for sustainable water supply solutions in the imminent future to provide and maintain service reliability, particularly in the face of climate change.
