Sustainable cities and human settlements

Nutrient recycling has been practiced for thousands of years in China to maintain food production without environmental pollution. In the past three decades, however, the traditional nutrient recycling systems have been replaced with waste treatment systems, which have resulted in rapid and severe environmental pollution.
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.
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. By means of semi-structured expert interviews, five areas with source separation were characterized and compared.
Disasters impacts on urban environment are the result of interactions among natural and human systems, which are intimately linked each other. What is more, cities are directly dependent on infrastructures providing essential services (Lifeline Systems, LS). The operation of LS in ordinary conditions as well as after disasters is crucial. Among the LS, drinking water supply deserves a critical role for citizens. The present work summarizes some preliminary activities related to an ongoing EU funded research project.
The Global Opportunity Explorer is a UN Global Compact platform which showcases the most innovative solutions, market opportunities and cities. Rooted in over five years of research involving 18,000 business leaders and 17 expert panels, the Explorer guides you through hundreds of sustainable solutions and market opportunities which address the SDGs (Sustainable Development Goals).

Green innovations will be significant in reducing climate change impacts and contributing to goals 9 (industry, innovation and infrastructure), 11 (sustainable cities and communities) and 13 (climate action). This chapter considers a number of sustainable and innovative transport and infrastructure options to support these goals.
The Blueprint for Business Leadership on the SDGs aims to inspire all business — regardless of size, sector or geography — to take leading action in support of the achievement of the Sustainable Development Goals (SDGs). It illustrates how the five leadership qualities of Ambition, Collaboration, Accountability, Consistency, and Intentional can be applied to a business' strategy, business model, products, supply chain, partnerships, and operations to raise the bar and create impact at scale. The Blueprint is a tool for any business that is ready to advance its principled approach to SDG action to become a leader. This chapter relates specifically to SDG 11.

Aquaponics is an innovative smart and sustainable production system for integrating aquaculture with hydroponic vegetable crops, that can play a crucial role in the future of environmental and socio-economic sustainability in smart cities. These cities aim mobilize all knowledge centers and Information and Communication Technologies (ICT) into innovation hubs in order to strengthen the socio-economic progress.
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.
