Urban Water Security


Book Description

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.




Sustainable Solutions for Urban Water Security


Book Description

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.

Water Security


Book Description

The world is on the brink of the greatest crisis it has ever faced: a spiraling lack of fresh water. Groundwater is drying up, even as water demands for food production, for energy, and for manufacturing are surging. Water is already emerging as a headline geopolitical issue—and worsening water security will soon have dire consequences in many parts of the global economic system. Directed by UN Secretary General Ban Ki-Moon at the 2008 Davos Annual Meeting, the World Economic Forum assembled the world’s foremost group of public, private, non-governmental-organization and academic experts to examine the water crisis issue from all perspectives. The result of their work is this forecast—a stark, non-technical overview of where we will be by 2025 if we take a business-as-usual approach to (mis)managing our water resources. The findings are shocking. Perhaps equally stunning are the potential solutions and the recommendations that the group presents. All are included in this landmark publication. Water Security contains compelling commentary from leading decision-makers, past and present. The commentary is supported by analysis from leading academics of how the world economy will be affected if world leaders cannot agree on solutions. The book suggests how business and politics need to manage the energy-food-water-climate axis as leaders negotiate the details of the climate regime that replace Kyoto Protocols.




Global Water Security


Book Description

This book highlights the relationship between the water sector and various other sectors in order to establish an improved understanding of the importance of water resources as an essential cross-cutting vector of socio-economic development. The book is both policy and practice oriented and is not constrained by existing definitions on water security. It includes actual experiences of policy, management, development and governance decisions taken within the water sector, and examples on how these have affected the energy and agricultural sectors as well as impacted the environment, and vice versa, as appropriate. It also discusses trade-offs, short and long-term implications, lessons learnt, and the way forward. The book includes case studies on cities, countries and regions such as Australia, China, Singapore, Central Asia, Morocco, Southern Africa, France, Latin America, Brazil and California.




Water and Cities


Book Description

This report focuses on the urban water management challenges facing cities across OECD countries, and explores both national and local policy responses with respect to water-risk exposure, the state of urban infrastructures and dynamics, and institutional and governance architectures. The analyses focus on four mutually dependent dimensions – finance, innovation, urban-rural co-operation and governance – and proposes a solutions-oriented typology based on urban characteristics. The report underlines that sustainable urban water management will depend on collaboration across different tiers of government working together with local initiatives and stakeholders.




Water, Climate Change, and Sustainability


Book Description

An in-depth review of sustainable concepts in water resources management under climate change Climate change continues to intensify existing pressures in water resources management, such as rapid population growth, land use changes, pollution, damming of rivers, and many others. Securing a reliable water supply—critical for achieving Sustainable Development Goals (SDGs)—requires understanding of the relation between finite water resources, climate variability/change, and various elements of sustainability.

Assessment Framework for Urban Water Security


Book Description

Urban water security is crucial for achieving sustainable development, peace, and human health and well-being. Framing urban water security is challenging due to the complexity and uncertainty of its definition and assessment framework. Several studies have assessed water security in widely divergent ways by granting priority indicators equal weight without considering or adapting to local conditions. This dissertation develops a new urban water security definition and assessment framework applicable to water scarce cities, with a focus on Madaba, Jordan. It takes a novel and systematic approach to assessing urban water security and culminates in integrated urban water security index (IUWSI) as a diagnostic tool and guide management actions. The dissertation suggests a new working definition of urban water security based on the United Nations (UN) Sustainable Development Goal 6.1 on safe drinking water for all and the human rights on water and sanitation as follows: The dynamic capacity of water systems and stakeholders to safeguard sustainable and equitable access to water of adequate quantity and acceptable quality that is continuously, physically and legally available at an affordable cost for sustaining livelihoods, human well-being and socioeconomic development, ensuring protection against waterborne pollution and water-related disasters, and for preserving ecosystems in a climate of peace and political stability. This proposed definition captures issues at the urban level of technical, environmental and socioeconomic indicators that emphasize credibility, legitimacy and salience. The assessment framework establishes a criteria hierarchy, consisting of four main dimensions to achieve urban water security: drinking water and human well-being, ecosystem, climate change and water-related hazards and socioeconomic aspects (together, DECS). The framework enables the analysis of relationships and trade-offs between urbanization, water security and DECS indicators. The dissertation also provides a structured analysis to understand how urban water is managed in intermittent water supply system, by conducting a water balance analysis after quantifying the components of water losses in Madaba’s water distribution network. The findings showed that Madaba's non-revenue water (NRW) amounted to annual loss of about 3.5 million m3, corresponding to financial losses of 2.8 million USD to the utility, of which 1.7 million USD is the cost of real losses. The dissertation provided an intervention strategy for strengthening infrastructure resilience and reducing leakage via the infrastructure, repair, economic, awareness and pressure (IREAP) framework. The IREAP framework provides a robust strategy to shift intermittent water supply (IWS) into continuous water supply. The IUWSI highlighted the state of water security in Madaba, Jordan and identified the means of implementation to move towards achieving urban water security based on the priorities for Madaba. The drinking water and human wellbeing dimension was the most important priority, receiving a weight of 66.22%, followed by ecosystem (17.15%), socioeconomic aspects (10.18%), and climate change and water-related hazards (6.45%) dimensions. The IUWSI indicated that the urban water security in Madaba is reasonable with a score of 2.5/5 and can meet the minimum requirements in several dimensions, but nonetheless, it has many loopholes to cover. Gaps are clear in the climate change and water-related hazards, and socioeconomic dimensions with scores of 1.6/5 and 2.237/5 respectively. Additionally, specific shortcomings are found in indicators such as water availability, reliability, diversity, and public health. The IUWSI framework assists with a rational and evidence-based decision-making process, which is important for enhancing water resource management in water-scarce cities

The Political Economy of Urban Water Security under Climate Change


Book Description

In 2018, the city of Cape Town faced the prospect of reaching ‘day zero’, that is a combination of natural and human-made factors leading to the complete collapse of its municipal water supply. While the rains eventually fell and a major disaster was averted, the fear of running out of water looms large in the psyche of residents in many cities around the world. Water is a non-substitutable, essential, finite and fugitive resource. It is the lifeblood of human endeavour. Cities, through global processes such as Agenda 2030 and forums such as ICLEI exchange best practices for achieving water security. These forums also are collective social spaces occupied by civil society organizations who share strategies and tactics, and the private sector, who compete for markets and contracts, promoting patent-protected technologies. It is these groups – states, civil societies, private sectors – coming together who determine who gets what water, when, and where. It is the job of academics to understand the how and why, and of (academic-)activists to fight for equity of access and sustainability of use. Evidence drawn from around the world and over time consistently shows that water flows toward money and power. Outcomes are too-often socially inequitable, environmentally unsustainable and economically inefficient. How to shift existing processes toward improved practices is not clear, but positive outcomes do exist. In this collection, we compare and contrast the challenges and opportunities for achieving urban water security with a focus on 11 major world cities: Bangalore, Beijing, Cairo, Cape Town, Chennai, Istanbul, Jakarta, London, Melbourne, Sao Paulo and Tokyo. Through the theoretical, conceptual and practical insights provided in these case studies, our collection constructively contributes to a global conversation regarding the ways and means of ‘avoiding day zero’.
