Abstract The article seeks to analyze the development of deforestation governance actions in the Amazon, based on the analysis of two case studies using the Strategic Action Fields theory (FLIGSTEIN; MCADAM, 2012). It analyzes the experience of mobilization for the removal of the city of Paragominas/PA from the deforestation Black List and the development of deforestation control actions in the São Jorge settlement, in the city of Cidelândia / Maranhão. Interviews with main actors and satellite images were used to analyze the two cases. The results indicate the relevance of using the Strategic Action Fields theory to gain an understanding of deforestation governance processes in the Amazon, highlighting the importance of central concepts to this theory, such as the performance of skilled social actors and the construction of internal units of governance.

This chapter considers how Wolof, an Atlantic language spoken in Senegal, has become an important lingua franca, and how French has contributed to the ascent of Wolof. The nature of social relations between Africans and French in cities along the Atlantic coast in the 18th and 19th centuries were such that a prestigious urban way of speaking Wolof that made liberal use of French borrowings became the language of the city. As an index of urban belonging, opportunity, and modernity, Wolof was viewed as a useful language, a trend that has continued up to the present. Four case studies illustrate how the use of Wolof facilitates mobility for speakers of other languages in Senegal. By drawing a distinction between the formal and informal language sectors, this chapter offers a more realistic view of everyday language practices in Senegal, where Wolof is the dominant language.

DSM generation from satellite imagery is a long-lasting issue and it has been addressed in several ways over the years; however, expert and users are continuously searching for simpler but accurate and reliable software solutions. One of the latest ones is provided by the commercial software Agisoft Metashape (since version 1.6), previously known as Photoscan, which joins other already available open-source and commercial software tools. The present work aims to quantify the potential of the new Agisoft Metashape satellite processing module, considering that to the best knowledge of the authors, only two papers have been published, but none considering cross-sensor imagery. Here we investigated two different case studies to evaluate the accuracy of the generated DSMs. The first dataset consists of a triplet of Pléiades images acquired over the area of Trento and the Adige valley (Northern Italy), which is characterized by a great variety in terms of geomorphology, land uses and land covers. The second consists of a triplet composed of a WorldView-3 stereo pair and a GeoEye-1 image, acquired over the city of Matera (Southern Italy), one of the oldest settlements in the world, with the worldwide famous area of Sassi and a very rugged morphology in the surroundings. First, we carried out the accuracy assessment using the RPCs supplied by the satellite companies as part of the image metadata. Then, we refined the RPCs with an original independent terrain technique able to supply a new set of RPCs, using a set of GCPs adequately distributed across the regions of interest. The DSMs were generated both in a stereo and multi-view (triplet) configuration. We assessed the accuracy and completeness of these DSMs through a comparison with proper references, i.e., DSMs obtained through LiDAR technology. The impact of the RPC refinement on the DSM accuracy is high, ranging from 20 to 40% in terms of LE90. After the RPC refinement, we achieved an average overall LE90 <5.0 m (Trento) and <4.0 m (Matera) for the stereo configuration, and <5.5 m (Trento) and <4.5 m (Matera) for the multi-view (triplet) configuration, with an increase of completeness in the range 5–15% with respect to stereo pairs. Finally, we analyzed the impact of land cover on the accuracy of the generated DSMs; results for three classes (urban, agricultural, forest and semi-natural areas) are also supplied.

Circular economy (CE) is an emerging concept that contrasts the linear economic system. This concept is particularly relevant for cities, currently hosting approximately 50% of the world’s population. Research gaps in the analysis and implementation of circular economy in cities are a significant barrier to its implementation. This paper presents a multi-sectorial and macro-meso level framework to monitor (and set goals for) circular economy implementation in cities. Based on literature and case studies, it encompasses CE key concepts, such as flexibility, modularity, and transparency. It is structured to include all sectors in which circular economy could be adopted in a city. The framework is then tested in Porto, Portugal, monitoring the circularity of the city and considering its different sectors.

Abstract This article examines affective responses to terror and the emergence of communities of sense in the commemoration of such attacks. We challenge the predominant framing of responses to terror which emphasize security and identity. We focus on the singular response by the city of Manchester in the aftermath of the 2017 Arena bombing, drawing on fieldwork conducted at the 1-year anniversary commemorative events. Our discussion focuses on the ways improvised, transient communities crystallized around the cultural significance of music during these events. The article explores these communities of sense through two case studies: those drawn together around the figure of Ariane Grande; and those assembled through a mass sing-along. In contrast to national or municipal responses to terror which orchestrate affect to establish narratives about security, borders and identity, we argue for the importance of paying attention to the improvised, affective ways in which people respond to terror. These plural, affective responses suggest another form of collective subjectivity. They also demonstrate the transient, plural, and everyday ways in which politics is practiced, assembled, and negotiated by different publics in response to terror.

This study aims to examine the effect of urban spatial patterns on heat exposure in the city of Tel Aviv using multiple methodologies, Local Climate Zones (LCZ), meteorological measurements, and remote sensing. A Local Climate Zone map of Tel Aviv was created using Geographic Information System (GIS), and satellite images were used to identify the spatial patterns of the urban heat island (UHI). Climatic variables were measured by fixed meteorological stations and by mobile cross-section. Surface and wall temperatures were obtained by satellite images and a hand-held infrared camera. Meteorological measurements at a height of 2 m showed that during midday the city is ~3.6 °C warmer than the surrounding rural area. The cooling effect of parks was evident only during the hot hours of the day (9:00–17:00). Land Surface Temperature in the southern part of the city was hotter by ~7–9 °C compared to the northern part due to lack of urban vegetation. Hot spots were found in compact midrise forms (LCZ 2) that are not ideal from the climatological perspective. Whereas compact low-rise forms (LCZ 3) were less heat vulnerable. The results of this study suggest that climatologists can provide planners and architects with scientific insight into the causes of and solutions for urban climatic heat exposure.

Augustine and the Humanists fills a persistent lacuna by investigating the reception of Augustine’s oeuvre in Italian humanism during the fourteenth and fifteenth centuries. In response to the call for a more extensive and detailed investigation of the reception of Augustine’s works and thought in the Western world, numerous scholars have addressed the topic over the last decades. However, one of Augustine’s major works, De civitate Dei, has received remarkably little attention. In a series of case studies by renowned specialists of Italian humanism, this volume now analyzes the various strategies that were employed in reading and interpreting the City of God at the dawn of the modern age. Augustine and the Humanists focuses on the reception of the text in the work of sixteen early modern writers and thinkers who played a crucial role in the era between Petrarch and Poliziano. The present volume thus makes a significant and innovative contribution both to Augustinian studies and to our knowledge of early modern intellectual history.

The pop-up architecture (or landscape architecture) becomes popular nowadays. Some highlights include annual architecture program such as the Serpentine Gallery Pavilion at Hyde Park, London; MPavilion in Melbourne; MoMA PS1 and Heart Sculpture in New York. Many of these pop-up architectural works have been designed by world renowned architects, such as Zaha Hadid, Rem Koolhaas, Hezorg and de Meuron, Jean Nouvel, Toyo Ito, SANAA, Shigeru Ban, BIG, etc. And many of these designs reflect innovative thinking that changes the professional world of architectural design. But above all, these pop-up architectures were created in responsive manner to the urban community and the community controversially has good response to this type of architecture. In the other words, pop-up architecture is the way the architects touch the heartbeat of the cities, make them livable for all. Ho Chi Minh City has its own types of pop-up landscape architecture, whereas this paper intends to explore in two case studies: Nguyen Hue Floral Boulevard and Nguyen Van Binh Book Street. Nguyen Hue Floral Street is celebrating now its twelfth birthday in the city. Nguyen Van Binh Book Street has just passed its first anniversary in 2017. Both cases live its own story behind the scene about how livable a city could be through place-making by architecture and landscape design. Throughout these cases, we would like to find out how this type of pop-up landscape architecture being realized and become popular in Ho Chi Minh City, and how it is devoted to a livable city for all.

In recent years, cars have steadily colonized the sidewalks in downtown Tbilisi. By driving and parking on sidewalks, vehicles have reshaped public space and placed pedestrian life at risk. A variety of social actors coordinate sidewalk affairs in the city, including the local government, a private company called CT Park, and a fleet of self-appointed st’aianshik’ebi (parking attendants) who direct drivers into parking spots for spare change. Pedestrian activists have challenged the automotive conquest of footpaths in innovative ways, including art installations, social media protests, and the fashioning of ad hoc physical barriers. By safeguarding sidewalks against cars, activists assert ideals for public space that are predicated on sharp boundaries between sidewalk and street, pedestrian and machine, citizen and commodity. Politicians and activists alike connect the sharpness of such boundaries to an imagined Europe. Georgia’s parking culture thus reflects not only local configurations of power among the many interests clamoring for the space of the sidewalk, but also global hierarchies of value that form meaningful distinctions and aspirational horizons in debates over urban public space. Against the dismal frictions of an expanding car system, social actors mobilize the idioms of freedom and shame to reinterpret and repartition the public/private distinction.

Cities are trying to adapt to the rapidly changing global trends by regenerating themselves. Approaches and practices of this regeneration are different in several countries. In big Turkish cities, particularly in the past decade, urban regeneration practices, processes and consequences have sparked several debates. The ?new? gained or converted spaces in the city are also significant in terms of their impacts on urban identity. In this context, this study aims to identify the impacts of urban regeneration, which occurred in historical city centres, on urban identity in the case of Turkey. The study determines general framework of urban regeneration and then defines a conceptual framework of urban identity. It focuses on urban regeneration projects in the case of Turkey. Then, the topic is explored through two case studies which are selected from Turkey, Istanbul and Bursa. The findings of the study indicate that there are several problematic aspects of urban regeneration. The findings also show that urban identity was ignored in urban regeneration projects, which caused significant breaks in the context of physical, cultural, historical and semantic continuity.

The intention of the Growth Plan for the Greater Golden Horseshoe is to create a planning framework that achieves complete communities and a thriving economy. However, there is minimal direction for municipalities planning for retail development to realize these goals. This is problematic, as e-commerce is disrupting the retail industry and is transforming the commercial and industrial real estate that support it. This paper examines e-commerce growth over the past thirteen years in Canada and demonstrates how this is prompting changes in both land markets through two case studies. Case studies identify implications that e-commerce will create for land use policy in Toronto moving forward. Recommendations presented to address these implications prompt upper levels of government to collect data to inform decision making at the municipal level. Recommendations for the City of Toronto are aimed at relaxing land use policies to create a strategy to facilitate efficient goods movement. Key words: E-commerce; Land Use Policy; Toronto, Canada
