A Technology Portfolio of Nature Based Solutions


Book Description

This book aims to define the concept of Nature Based Solutions (NBS) by using case studies from members of the European Innovation Partnership (EIP) Water Action Group - NatureWat. NBS is defined and characterized in terms of water source, contaminants, removal mechanisms and resource recovery potential. The case studies presented illustrate the appropriateness of NBS promoting climate resilience. Readers will discover a technology portfolio based on a number of demonstration sites in the fields of climate change adaption, water and wastewater treatment, resource recovery and re-use, and restoring ecosystems to promote the use of nature based solutions. The chapters in the book present a multidisciplinary approach involving social scientists, governance representatives and engineers. The underlying philosophy of the book is the circular economy of water which prioritizes the concepts of resource recovery and resilience within water resource management. The first section of the book presents the background and objectives of the study, and how the action group aims to promote the use of nature based solutions through its diverse technology portfolio. Particular attention is given to the goals of finding cost-effective solutions for wastewater treatment, climate change mitigation, disaster risk reduction, flood protection, greening cities, degraded areas restoration and biodiversity preservation. The chapter on reclaimed water addresses water reuse and defines the term fit for purpose. Barriers and limitations related to NBS for water resource management are discussed. The book concludes with several case studies at local, regional and global levels which illustrate a new approach to water management. These case studies illustrate the application of a hybrid green and grey infrastructure system. This is a combination of traditional engineered infrastructure with nature based solutions which combines centralised and decentralised systems to optimise the reclamation of water for reuse in a fit for purpose model.

Nature Based Solutions for Wastewater Treatment


Book Description

There are 2.4 billion people without improved sanitation and another 2.1 billion with inadequate sanitation (i.e. wastewater drains directly into surface waters), and despite improvements over the past decades, the unsafe management of fecal waste and wastewater continues to present a major risk to public health and the environment (UN, 2016). There is growing interest in low cost sanitation solutions which harness natural systems. However, it can be difficult for wastewater utility managers to understand under what conditions such nature-based solutions (NBS) might be applicable and how best to combine traditional infrastructure, for example an activated sludge treatment plant, with an NBS such as treatment wetlands. There is increasing scientific evidence that treatment systems with designs inspired by nature are highly efficient treatment technologies. The cost-effective design and implementation of ecosystems in wastewater treatment is something that exists and has the potential to be further promoted globally as both a sustainable and practical solution. This book serves as a compilation of technical references, case examples and guidance for applying nature-based solutions for treatment of domestic wastewater, and enables a wide variety of stakeholders to understand the design parameters, removal efficiencies, costs, co-benefits for both people and nature and trade-offs for consideration in their local context. Examples through case studies are from across the globe and provide practical insights into the variety of potentially applicable solutions.




Urban Sustainability Transitions


Book Description

The world’s population is currently undergoing a significant transition towards urbanisation, with the UN expecting that 70% of people globally will live in cities by 2050. Urbanisation has multiple political, cultural, environmental and economic dimensions that profoundly influence social development and innovation. This fundamental long-term transformation will involve the realignment of urban society’s technologies and infrastructures, culture and lifestyles, as well as governance and institutional frameworks. Such structural systemic realignments can be referred to as urban sustainability transitions: fundamental and structural changes in urban systems through which persistent societal challenges are addressed, such as shifts towards urban farming, renewable decentralised energy systems, and social economies. This book provides new insights into how sustainability transitions unfold in different types of cities across the world and explores possible strategies for governing urban transitions, emphasising the co-evolution of material and institutional transformations in socio-technical and socio-ecological systems. With case studies of mega-cities such as Seoul, Tokyo, New York and Adelaide, medium-sized cities such as Copenhagen, Cape Town and Portland, and nonmetropolitan cities such as Freiburg, Ghent and Brighton, the book provides an opportunity to reflect upon the comparability and transferability of theoretical/conceptual constructs and governance approaches across geographical contexts. Urban Sustainability Transitions is key reading for students and scholars working in Environmental Sciences, Geography, Urban Studies, Urban Policy and Planning.




Nature-Based Solutions to 21st Century Challenges


Book Description

This book provides a systematic review of nature-based solutions and their potential to address current environmental challenges. In the 21st century, society is faced by rapid urbanisation and population growth, degradation and loss of natural capital and associated ecosystem services, an increase in natural disaster risks, and climate change. With growing recognition of the need to work with ecosystems to resolve these issues there is now a move towards nature-based solutions, which involve utilising nature’s ecosystem to solve societal challenges while providing multiple co-benefits. This book systematically reviews nature-based solutions from a public policy angle, assessing policy developments which encourage the implementation of nature-based solutions to address societal challenges while simultaneously providing human well-being and biodiversity benefits. This includes enhancing sustainable urbanisation, restoring degraded ecosystems, mitigating and adapting to climate change, and reducing risks from natural disasters. While nature-based solutions can be applied strategically and equitably to help societies address a variety of climatic and non-climatic challenges, there is still a lack of understanding on how best to implement them. The book concludes by providing a best practice guide for those aiming to turn societal challenges into opportunities. This book will be of great interest to policymakers, practitioners and researchers involved in nature-based solutions, sustainable urban planning, environmental management, and sustainable development generally.




Nature-Based Solutions for Flood Mitigation


Book Description

This book provides an overview of the typical nature-based solutions (NBS) used for flood mitigation at different scales and in different areas (e.g. from catchment to hillslope scale; from urban to coastal areas). NBS can provide several ecosystem services, such as water regulation and water quality enhancement, and as such offer relevant technical solutions to complement typical grey infrastructures to mitigate flood hazard and water quality problems. In recent years, political awareness and interest from the scientific community have led to increasing implementation of NBS worldwide. In light of this trend, this book provides valuable insights into the environmental aspects of NBS, particularly their effectiveness for flood and pollution mitigation, and discusses socio-economic aspects related to the implementation of NBS, including regulatory aspects, cost, and citizens’ perceptions of NBS. Compiling the latest research, the book furthers our understanding of the role of NBS for flood mitigation and its relation to environmental aspects, to guide scientists and stakeholders in future NBS projects. It is intended for the scientific community and stakeholders, such as spatial planners and landscape managers.
