Urban agriculture comes with its own share of environmental impacts. Circular strategies promise to reduce these impacts, but not all strategies are resource efficient and environmentally effective.

This paper finds that the most eco-friendly and circular strategies for urban agriculture, taking a Mediterranean tomato crop as a case study, include:

• Struvite (phosphate mineral recovered from wastewater treatment) instead of non-renewable phosphate fertiliser to conserve freshwater
• Recycled steel and materials for urban agricultural infrastructure to reduce carbon emissions, toxicity and freshwater pollution
• Closed-loop irrigation to minimise ocean and freshwater pollution. However, if new infrastructure is required, it could lead to an increase in carbon emissions.

The circular economy (CE) is gaining momentum in cities. To ensure a sustainable CE, it is crucial to measure the environmental performance of CE strategies. However, environmental assessments overlook several strategies that are a key feature of urban CE practice. These include reuse and repair, sustainable built infrastructure and urban land use, green public procurement, smart information and access technology.

To provide insights into the environmental performance and potential of these strategies, industrial ecologists and municipalities should:

• collaborate with urban systems experts
• quantify the environmental impacts of entire urban systems
• combine environmental assessments with social and economic feasibility ones.

This book provides answers on how to govern the transition to a circular economy in different socio-cultural and political contexts.

It is intended to help the global changemakers who are building our circular future. Author Jacqueline Cramer spoke with 20 representatives of circular hotspots worldwide, thoroughly analysed their different contexts and extracted 10 key takeaways. Everyone working on circular initiatives can use these and adapt them to their own socio-cultural and political contexts.

In this book, Jacqueline Cramer shows how network governance can power the circular economy. Network governance is about building a coalition of partners, which all fulfill a specific function in the network and are aligned by so-called transition brokers. By complementing conventional, public governance with this new form of governance, the best of both worlds is created.

Prof. Cramer shares her huge experience of implementing numerous circular initiatives in the Netherlands. As a practitioner and scholar, she has identified ten guiding principles for building circular initiatives, based on network governance. These guidelines can support everyone who wants to start or expedite a circular initiative.

This is a guide to help practitioners in a city government to adopt a more circular approach to public procurement. Public procurement processes differ from one city to another and therefore this guide is not a one-size-fits-all solution. Instead, it provides an overarching framework that should be adapted to the local context and the realities of a city.

Users are not expected to read the guide in full from beginning to end, but rather, once they have read the framework overview, to jump to the section they need by using the menu bar on the left.
