In a rapidly urbanizing and globalized world, cities have been the epicentres of COVID-19 (coronavirus). The virus has spread to virtually all parts of the world; first, among globally connected cities, then through community transmission and from the city to the countryside. This report shows that the intrinsic value of sustainable urbanization can and should be harnessed for the wellbeing of all. It provides evidence and policy analysis of the value of urbanization from an economic, social and environmental perspective. It also explores the role of innovation and technology, local governments, targeted investments and the effective implementation of the New Urban Agenda in fostering the value of sustainable urbanization.

Abstract: This paper provides the key elements to develop an integrated approach for measuring and monitoring city performance globally. The paper reviews the role of cities and why indicators are important. Then it discusses past approaches to city indicators and the systems developed to date, including the World Bank's initiatives. After identifying the strengths and weaknesses of past experiences, it discusses the characteristics of optimal indicators. The paper concludes with a proposed plan to develop standardized indicators that emphasize the importance of indicators that are measurable, replicable, potentially predictive, and most important, consistent and comparable over time and across cities. As an innovative characteristic, the paper includes subjective measures in city indicators, such as well-being, happy citizens, and trust.

Cities have experienced an unprecedented rate of growth in the last decade. More than half the world's population lives in urban areas, with the U.S. percentage at 80 percent. Cities have captured more than 80 percent of the globe's economic activity and offered social mobility and economic prosperity to millions by clustering creative, innovative, and educated individuals and organizations. Clustering populations, however, can compound both positive and negative conditions, with many modern urban areas experiencing growing inequality, debility, and environmental degradation. The spread and continued growth of urban areas presents a number of concerns for a sustainable future, particularly if cities cannot adequately address the rise of poverty, hunger, resource consumption, and biodiversity loss in their borders. Intended as a comparative illustration of the types of urban sustainability pathways and subsequent lessons learned existing in urban areas, this study examines specific examples that cut across geographies and scales and that feature a range of urban sustainability challenges and opportunities for collaborative learning across metropolitan regions. It focuses on nine cities across the United States and Canada (Los Angeles, CA, New York City, NY, Philadelphia, PA, Pittsburgh, PA, Grand Rapids, MI, Flint, MI, Cedar Rapids, IA, Chattanooga, TN, and Vancouver, Canada), chosen to represent a variety of metropolitan regions, with consideration given to city size, proximity to coastal and other waterways, susceptibility to hazards, primary industry, and several other factors.

Over 100 scientists, architects, journalists, artists and activists address creatively the unprecedented challenges facing an Urban Planet. This title is also available Open Access.

Case study rich, this volume advances our understanding of the significance of 'the city' in global governance. The editors call for innovation in international relations theory with case studies that add breadth to theorizing the role sub-national political actors play in global affairs. Each of the eight case studies demonstrates different intersections between the local and the global and how these intersections alter the conditions resulting from globalization processes. The case studies do so by focusing on one of three sub-themes: the diverse ways in which cities and sub-national regions impact nation-state foreign policy; the various dimensions of urban imbrications in global environmental politics; or the multiple methods and standards used to measure the global roles of cities.

The Challenge of Slums presents the first global assessment of slums, emphasizing their problems and prospects. Using a newly formulated operational definition of slums, it presents estimates of the number of urban slum dwellers and examines the factors at all level, from local to global, that underlie the formation of slums as well as their social, spatial and economic characteristics and dynamics. It goes on to evaluate the principal policy responses to the slum challenge of the last few decades. From this assessment, the immensity of the challenges that slums pose is clear. Almost 1 billion people live in slums, the majority in the developing world where over 40 per cent of the urban population are slum dwellers. The number is growing and will continue to increase unless there is serious and concerted action by municipal authorities, governments, civil society and the international community. This report points the way forward and identifies the most promising approaches to achieving the United Nations Millennium Declaration targets for improving the lives of slum dwellers by scaling up participatory slum upgrading and poverty reduction programmes. The Global Report on Human Settlements is the most authoritative and up-to-date assessment of conditions and trends in the world's cities. Written in clear language and supported by informative graphics, case studies and extensive statistical data, it will be an essential tool and reference for researchers, academics, planners, public authorities and civil society organizations around the world.

The report presents findings from the 2018 revision of World Urbanization Prospects, which contains the latest estimates of the urban and rural populations or areas from 1950 to 2018 and projections to 2050, as well as estimates of population size from 1950 to 2018 and projections to 2030 for all urban agglomerations with 300,000 inhabitants or more in 2018. The world urban population is at an all-time high, and the share of urban dwellers, is projected to represent two thirds of the global population in 2050. Continued urbanization will bring new opportunities and challenges for sustainable development.

Cities have led the way to combat climate change by planning and implementing climate mitigation and adaptation policies. These local efforts go beyond national boundaries. Cities are forming transnational networks to enhance their understandings and practices for climate policies. In contrast to national governments that have numerous obstacles to cope with global climate change in the international and national level, cities have become significant international actors in the field of international relations and environmental governance. Global Cities and Climate Change examines the translocal relations of cities that have made an international effort to collectively tackle climate change. Compared to state-centric terms, international or trans-national relations, trans-local relations look at policies, politics, and interactions of local governments in the globalized world. Using multi-methods such as multi-level analysis, comparative case studies, regression analysis and network analysis, Taedong Lee illustrates why some cities participated in transnational climate networks for cities; under what conditions cities internationally cooperate with other cities, with which cities; and which factors influence climate policy performance. An essential read to all those who wish to understand the driving factors for local governments’ engagement in global climate governance from a theoretical as well as practical point of view. Lee makes a valuable contribution to the fields of international relations, environmental policies, and urban studies.
