Ecosystem Services For Urban Water Security

The book addresses the challenges of urban water security and adaptive management in Sub-Saharan Africa, exploring and interlinking novel concepts of ecosystems services, watershed investments, and boundary work. Specifically, the book’s goals are to (i) present a conceptual framework for the urban water sector from an ecosystem services perspective, highlighting the specificities of the Sub-Saharan context; (ii) develop an operational approach to designing and assessing the impacts of watershed investments, based on ecosystem services and boundary work; and (iii) test the approach through a case study in Asmara, Eritrea, and discuss the findings and lessons learned that can be applied in other contexts. Through a fully worked out case study, from identification of water challenges and opportunities to spatially explicit modelling, the book offers a sound and accessible, coverage of issues and proposed solutions to better operationalize ecosystem services, watershed investments and boundary work, to promote adaptive management, and achieve water security in the context of rapidly developing cities in Sub-Saharan Africa. The book is an effective tool for capacity building of diverse stakeholders on the urban water sector, including water managers, local and national policy-makers as well as a suitable resource for both undergraduate and post-graduate courses in planning and geography.

This book presents solutions to address water security in rapidly urbanizing cities, and explores the new paradigms of water security in changing contexts. Highlighting the latest developments in water research, changes in water policy, and current discourses on water security, the book also provides information and tools for local stakeholders, water managers, and policymakers to build the capacity for sustainable water governance. The book discusses a wide range of sustainable solutions and their implementation to ensure that the balance between water supply and demand remains sustainable in the long term, with a focus on local solutions to build capacity and developing policy awareness for a wide range of stakeholders. As the concept of urban water security in changing contexts is open to multiple interpretations, the authors set out various approaches. Providing an overview of the changing perspectives of urban water security in different contexts, the book is based on findings of the Asia-Pacific Network water security project at the United Nations University, Tokyo, as well as the authors' current research-based at Pokhara University, Nepal, Hosei University, Tokyo, Institute for the Global Environmental Strategies, Japan and the Australian National University, Australia. The book also includes the views of international authorities (such as water experts) on the subject. The solutions are complemented by analysis of case studies of various localized sustainable solutions at different scales. The book is a valuable resource for water professionals and policymakers around the globe, academics, teachers working in water-related areas, NGOs, think thanks, water research institutes, donor organizations, and international and local water utility services.

In the 21st Century, the world will see an unprecedented migration of people moving from rural to urban areas. With global demand for water projected to outstrip supply in the coming decades, cities will likely face water insecurity as a result of climate change and the various impacts of urbanisation. Traditionally, urban water managers have relied on large-scale, supply-side infrastructural projects to meet increased demands for water; however, these projects are environmentally, economically and politically costly. Urban Water Security argues that cities need to transition from supply-side to demand-side management to achieve urban water security. This book provides readers with a series of in-depth case studies of leading developed cities, of differing climates, incomes and lifestyles from around the world, that have used demand management tools to modify the attitudes and behaviour of water users in an attempt to achieve urban water security. Urban Water Security will be of particular interest to town and regional planners, water conservation managers and policymakers, international companies and organisations with large water footprints, environmental and water NGOs, researchers, graduate and undergraduate students.

The population of cities around the world is growing at an alarming rate, and as a result the landscapes of most cities are going through enormous changes. In particular, fertile agricultural lands at the periphery of cities are being developed without consideration of holistic planning. As such, peri-urban areas, zones of transition from rural to urban land uses located between the outer limits of the urban and the rural environment are experiencing significant losses of agricultural land, increased runoff, and water quality degradation. Concurrently, the demands for water, food and energy are increasing within cities, and unless a balance is struck the liveability of these cities will soon be compromised. The current water and land use changes have serious consequences on lifestyle, environment, health and overall well-being of urban communities. This book therefore helps readers to understand the current issues and challenges and examines suitable strategies and practices to cope with current and future pressures of urbanisation and peri-urban land-use changes. The book examines a number of critical aspects in relation to the future of cities and peri-urban regions, including the suitability of policies and institutions to sustain cities into the future; impact of current trends in land use change, population increase and water demand; long term planning needs and approaches to ensure the secured future for generations ahead; and strategies to adapt the cities and land uses so that they remain viable and liveable. The readership of the book will include policy makers, urban planners, researchers, post-graduate students in urban planning and environmental and water resources management and managers in municipal councils.

This book provides unique insights into the complex issue of water security in South Africa. Based on qualitative research conducted through face-to-face structured interviews and focus group discussions with individuals, traditional leaders, municipal officials, researchers, businesspeople and farmers in the two local governments – the Sekhukhune District and eThekwini Metropolitan Municipalities – it focuses on the peoples’ understanding of the concept of water security and whether they believe that the municipalities have achieved water security for all. The research is supported by water security-related statistics, particularly those pertaining to water quality and quantity, and an extensive literature review for the concept of water security. In addition to assessing the state of water security in both municipalities, the book presents a new water security definition and typology, and offers valuable recommendations for future research.
