This paper aims to advance the idea of sustainable flood reduction. Flood reduction through the use of the drainage system is considered an unsustainable approach that decreases the use of water. In contrast, the Water Sensitive City is a sustainable concept aimed at increasing the value of water for human needs and reduce flooding.

The current approach of relying on drainage systems is ineffective and must be combined with green infrastructures to reduce flooding. Green infrastructures can increase infiltration rates or facilitate rain harvesting. The study developed four scenarios that combine green and grey infrastructures and used the Soil and Water Assessment Tool (SWAT) model to select the most effective scenario based on the remaining amount of flood volume in every scenario.

Green infrastructures that are related to increased infiltration and rain-harvesting instruments reduced flooding by 22.3 and 27.7 per cent, respectively. Furthermore, a combination of the two types of green infrastructures reduced flooding up to 45.5 per cent. Conversely, applying only grey infrastructures (by increasing drainage capacity) to reduce the flooding to zero is unfeasible, as this requires more than double the current capacity. Therefore, a combination of green and grey infrastructures can significantly reduce flooding in a water sensitive and feasible manner.

Applying a combination of green and grey infrastructures is a new and effective approach to reduce flooding in the Kedurus Catchment Area.

The “renaturing” of cities through an increased emphasis on the use of nature-based solutions (NBS) potentially offers urban areas the opportunity to deliver multiple environmental and socioeconomic benefits. In particular, approaches linked to NBS can limit the degree of climate exposure and vulnerability impacting upon urban infrastructures. The success of NBS in addressing climate change pressures will require an improved understanding of the characteristics of environmental risk and the ability to evaluate alternate adaptive pathways. In response, this chapter explores those components which are central to effective urban infrastructure assessment and considers how they may assist in the formulation of infrastructure strategies.

We stress the need for an approach which is both scenario-focused and fully integrated within existing spatial planning frameworks. Here, we draw specific attention to the utility of strategic environmental assessment (SEA) in both embedding environmental evaluation within mainstream spatial planning and providing the basis for the comparative evaluation of alternatives. We also argue for an approach which recognizes areas of complementary interaction between “gray infrastructure” (whether existing or proposed) and approaches linked to NBS. In order to highlight examples of potential development responses, we draw on best-practice case study examples from the European Union (EU)–funded GROWGREEN project.

The proverbial administrative complexity of Paris and its region, which also includes a metropolitan authority since 2016, has not prevented multiple and rapid changes to take place in the last decade. A national government decision has initiated the construction of a new regional metropolitan public transportation infrastructure that has leveraged more than €15 billions of green bonds. Mounting environmental challenges are triggering new societal priorities and legal changes, heightened by the COVID-19 crisis context. Since 2014, projects and plans led by local governments to value nature-based solutions (NBS) have met a rising interest from national and international investors and developers, in a context of multiple climate and biodiversity initiatives from the private sector and the civil society. However, assessing their long-term value remains a challenge for both governments and researchers while the calls for nature to remain a common good stir new forms of vigorous social engagement. The Paris case shows that the art of creating NBS that maximize biodiversity and support CO₂ reduction at large metropolitan scale depends on two priorities. The first is strengthening global commitments. The second is refocusing existing massive investments in grey infrastructure systems, so far major drivers of public investments, as infrastructure for distribution, unlocking local biodiversity valuation potential, and supporting social innovation.

The chapter tries to trace the development of concept of urban ecosystem as a problem-solving approach for urban problems, including the unwarranted problems caused by climate change. Urban management has increasingly shifted from infrastructure-based to a more regional-based approach. There has been a shift in the domain of urban ecosystem as well, from the established urbanized area to the aggregation of urban and surrounding rural area. Also, urban-rural linkages are given more attention in resource management in urban areas, thereby reducing the overall risk due to climate change. The chapter provides examples and challenges of urban ecosystem management from across the world.

The transition to a low carbon future is an emerging challenge and requires the planning and designing of sustainable energy landscapes – landscapes that provide renewable energy while safeguarding the supply of other ecosystem services. The aim of this paper is to present the application of an ecosystem services trade-off assessment in the development of sustainable energy landscapes for long-term strategic planning in a case study in Schouwen-Duivenland, The Netherlands.

The application consists in three activities: in (1) stakeholder mapping hot spots of ecosystem services and renewable energy technologies in a workshop, (2) landscape design principles being discussed by a focus group, (3) experts gathering the information and proceeding with an assessment of the potential synergies and trade-offs.

The case study indicates that (1) deploying the ecosystem services framework in planning and design can enhance the development of sustainable energy landscapes, (2) diversified and accurate spatial reference systems advance the trade-off analysis of both regulating and cultural ecosystem services and (3) the involvement of local stakeholders can advance the trade-off analysis and, ultimately, facilitates the transition to a low-carbon future with sustainable energy landscapes.

The originality of this research lies in the creation of an approach for the deployment of ecosystem services in the planning and design of energy transition. This is useful to advance energy transition by enhancing research methods, by providing methods useful for planners and designers and by supporting communities pursuing energy self-sufficiency in a sustainable manner.

The purpose of the article is to present some preliminary findings and discussions points from a symposium on Public Outdoor Spaces and COVID-19 organised in Wageningen, The Netherlands, in June 2021.

The article argues for a salutogenic perspective on infrastructure planning and design, dealing with the interplay between the ideas and practices of infrastructure planning and design and the outcomes of those ideas and practices for health.

Within that perspective, the coronavirus (COVID-19) crisis is seen as an opportunity to revive the importance of infrastructure in promoting health and well-being.

The salutogenic approach adds a much-needed new perspective on infrastructure planning and design, and also involves challenges both in research and practice, for the application of holistic principles to the design of new environments.

To report on the Sixth International Conference on Grey Literature held in New York, December 2004.

The report is prepared by a library professional who adds her own impartial comments.

This conference suggests the changing priorities in grey literature and how much more mainstream it has become with alternative publishing products and a wider awareness of scholarly communication principles and issues.

This is a useful summary of a conference of interest to library and information management professionals.

Globally, urban planners and decision makers are pursuing place-based initiatives to develop and enhance urban infrastructure to optimise city performance, competitiveness and sustainability credentials. New discourses associated with big data, Building Information Modelling, SMART cities, green and biophilic thinking inform research, policy and practice agendas to varying extents. However, these discourses remain relatively isolated as much city planning is still pursued within traditional sectoral silos hindering integration. This research explores new conceptual ground at the Smart – Natural City interface within a safe interdisciplinary opportunity space. Using the city of Birmingham UK as a case study, a methodology was developed championing co-design, integration and social learning to develop a conceptual framework to navigate the challenges and opportunities at the Smart-Natural city interface. An innovation workshop and supplementary interviews drew upon the insights and experiences of 25 experts leading to the identification of five key spaces for the conceptualisation and delivery at the Smart-Natural city interface. At the core is the space for connectivity; surrounded by spaces for visioning, place-making, citizen-led participatorylearning and monitoring.The framework provides a starting point for improved discussions, understandings and negotiations to cover all components of this particular interface. Our results show the importance of using all spaces within shared narratives; moving towards ‘silver-green’ and living infrastructure and developing data in response to identified priorities. Whilst the need for vision has dominated traditional urban planning discourses we have identified the need for improved connectivity as a prerequisite. The use of all 5 characteristics collectively takes forward the literature on socio-ecological-technological relationships and heralds significant potential to inform and improve city governance frameworks, including the benefits of a transferable deliberative and co-design method that generates ownership with a real stake in the outcomes.

The essence of finance has become essential in the sustainability discussion in recent times as a result of the capital intensive nature of sustainable projects. This has motivated financial experts and institutions to develop various financial instruments and mechanisms to further advance the course of protecting the environment, and decreasing the release of excess carbon and GreenHouse Gases. This is to also provide the opportunity for funding Green or sustainable infrastructure development. This chapter advances a discourse on matters relating to sustainable financing of infrastructure projects. The fundamentals of sustainable or green funding of infrastructure projects, and sustainable schemes of financing green infrastructure projects are discussed.

Chapter 17 discusses challenges for financing nature-based solutions (NBS). Financing NBS is a key challenge to ensure scaling of the use of NBS in urban areas. This is mainly due to the difficulty to monetize the value generated through the provisioning of ecosystem services, as well as the multiple cobenefits that NBS provide. Certain types of NBS, such as green roofs, have been able to allow for private value capture, enabling such projects to attract private or blended capital. Others, where benefits are generally regarded as public good, have to rely on different financing strategies and instruments. The section provides an overview of financing solutions (public, private, and blended instruments) for different types of NBS and their applicability to NBS in the urban context.
