"After four decades of reform and development, China is confronting a domestic waste crisis. As the world's largest waste-generating nation, the World Economic Forum projects that by 2030, the volume of household waste in China will be double that of the United States. Starting in the early 2000s, Chinese policymakers came to see waste management as an object of environmental governance central to the creation of "modern" cities, and experimented with the circular economy, in which technology and new policy could convert all forms of waste back into resources. Based on long-term research in Guangzhou, Circular Ecologies critically analyzes the implementation of technologies and infrastructures to modernize a mega-city's waste management system, and the grassroots ecological politics that emerged in response. In Guangzhou, waste's transformation revealed uncomfortable truths about China's mode of environmental governance: a preference for technology over labor, the aestheticization of order, and the expropriation of value in service of an ecological vision. Amy Zhang argues that in post-reform China, waste--the material vestige of decades of growth and increasing consumption--is a systemic irritant that troubles China's technocratic governance. Waste provoked an unlikely political coalition of urban communities, from the middle class to precarious migrant workers, that came to constitute a nascent, bottom-up environmental politics, and offers a model for conceptualizing ecological action under authoritarian conditions"--

This book advances the reflexion into how temporary urbanism is shaping cities across the world. Temporary urbanism has become a core concept in urban development, and its application is increasingly crossing the borders of both the North and the Global South. There is a need to reflect upon the diverse ways of understanding and implementing the temporary in the production of space internationally and discuss what this means, for both research and practice. Divided into two sections, the book compiles and reflects upon the various attempts to reframe and reconceptualise temporary urbanism. The first section focuses on reframing and reconceptualising temporary urbanisms. It develops the argument that temporary urbanism allows a reinterrogation of the role of temporalities and non-permanence into the place-making process and hence in the production and reproduction of cities, including the adaptability of existing spaces and production of new spaces. While drawing upon different theoretical and conceptual framings (permeability, assemblage, rhythms, waiting, …), authors bring insights from various case studies: the Dublin Biennial (Ireland), temporary uses in Geneva (Switzerland), temporary urban settlements in sub-Saharan Africa, refugees’ camp in Beirut (Lebanon) and political protests in Skopje (Republic of Macedonia). The second section looks at unwrapping the complexity and diversity of temporary urbanisms. It aims at securing a better understanding of the complexity and diversity of temporary urbanism, including a dialogue between various experiences both in the Global North and in the Global South. It looks at the implications of temporary urbanism in the delivery of planning and considers how and by whom cities are governed and transformed. Again, a range of examples are mobilised by contributors spanning from temporary uses and projects in London (UK), Santiago (Chile), Paris (France), Vancouver (Canada), Barcelona (Spain), Budapest (Hungary), Beijing (China), Sao Paulo (Brazil) and Milwaukee (USA). This book will be of interests to all researchers, practitioners, and students who want to gain a more thorough understanding of the topic of temporary urbanism, compare its diversity and similarities across different contexts, and reflect on the wider implications of temporary urbanisms for urban transformations.

We study the opposing deterrent and enabling effects of guns carried by law-abiding citizens on violent crime, using the location of shooting ranges as an instrument. Our incident-level data based on admittedly imperfect data from the Gun Violence Archive suggests that defensive gun use (DGU) by crime victims may decrease the probability of their injury or death, while increasing the risk of death or injury by the criminal suspects. However, in the aggregate, higher numbers of defensive gun uses--which proxies for more gun carrying and use--are associated with higher numbers of violent crimes, injuries, and fatalities among victims and suspects alike. We hypothesize that this equilibrium effect arises because more guns being carried and used by citizens produce more incentive and opportunities for criminals to acquire guns, leading to a commensurate increase in the incidence and lethality of crime. In summary, our analysis supports the conclusion that the widespread carrying and use of guns is overall more likely to enable violent crimes than to deter them.

High resolution datasets of population density which accurately map sparsely distributed human populations do not exist at a global scale. Typically, population data is obtained using censuses and statistical modeling. More recently, methods using remotely-sensed data have emerged, capable of effectively identifying urbanized areas. Obtaining high accuracy in estimation of population distribution in rural areas remains a very challenging task due to the simultaneous requirements of sufficient sensitivity and resolution to detect very sparse populations through remote sensing as well as reliable performance at a global scale. Here, the authors present a computer vision method based on machine learning to create population maps from satellite imagery at a global scale, with a spatial sensitivity corresponding to individual buildings and suitable for global deployment.
