Urban source separation infrastructure systems have a promising potential for a more sustainable management of household food waste and wastewaters. A renewed trend of larger implementations of pilot areas with such systems is currently emerging in Northern Europe. This study investigates the drivers behind the decision of stakeholders to implement source separation systems as well as the importance of the previously existing pilot areas in the decision-making process.

Cities are strongly dependent on infrastructures providing essential services, namely Lifeline Systems (LS) that support societal functions, safety, economic prosperity and quality of life. The operation of LS in ordinary conditions as well as after disasters is crucial. The main aim of the paper is to define a System Dynamic Model (SDM) to assess the evolution of resilience of a drinking water supply system in case of natural disasters, with particular attention to the role of both ‘structural’ and ‘non-structural’ parameters drawing on the L’Aquila (Italy) earthquake as a case study.
An international review of stormwater regulation and practices, especially for low-exposure, landscape irrigation schemes in urban environments, was undertaken with a view to identifying what could be used in Alberta, Canada. A general lack of clear guidance and regulation to manage stormwater quality and potential public health risks was identified, which could be hindering the uptake of stormwater schemes generally.This related to SDG6 and SDG 11.

This book chapter addresses goals 6 and 12 by providing an overview of water resources in Europe and the associated anthropogenic and natural pressures. It further introduces the main instrument of the European Union (the Water Framework Directive) initiated as a response to the expected water crisis.

Contributing to SDGs 6, 7 and 13, this paper discusses the CO2 footprint of California’s drought during 2012–2014. The authors show that California drought significantly increased CO2 emissions of the energy sector by around 22 million metric tons, indicating 33% increase in the annual CO2 emissions compared to pre-drought conditions. They argue that CO2 emission of climate extremes deserve more attention, because their cumulative impacts on CO2 emissions are staggering. Most countries, including the United States, do not have a comprehensive a nationwide energy-water plan to minimize their CO2 emissions, therefore the authors argue that developing a national water-energy plan under a changing climate should be prioritized in the coming years.

The sustainability of urban water systems is often compared in small numbers of cases selected as much for their familiarity as for their similarities and differences. Few studies examine large urban datasets to conduct comparisons that identify unexpected similarities and differences among urban water systems and problems. This work supports quantitative comparison of urban water sustainability. Cities were clustered to identify a typology of urban water management profiles. Clustering was based on per capita consumption, population, and annual water budget. This relates to SDG 6, 11 and 12.
This study used social indicators to assess stormwater management. There is a lack of awareness about environmental regulations related to fertilizer use. Social dimensions are crucial in sustainable stormwater management. This addresses SDG 6 and SDG 11.
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. This article provides a framework for adaptation planning in urban water supply systems relating to SDG 6 and SDG 11.

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. This relates to SDG 6 and SDG 11.
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. Anticipatory models enable long-term policy analysis for climate change. Mega-drought results in unsustainable groundwater use between 2000 and 2060. Aggressive drought management policies can produce sustainable yield. The time to manage droughts is before they occur. This relates to SDG 6, SDG 11 and SDG 13.
