Brazil’s Financial Centers in the Twenty-first Century: Hierarchy,Specialization, and Concentration

The purpose of this article is to examine how the geography of Brazil’s financial centers changed since 2000 in terms of financial center hierarchy, specialization, and spatial concentration. To address these questions, we use data on employment and mergers and acquisitions in financial and business services, complemented with data on remuneration and bank assets. Our results show that São Paulo has consolidated its dominance as Brazil’s primary financial center, with market for corporate control as an important channel of this process. Rio’s decline as a financial center, which started more than fifty years ago, has continued into this century. At the same time, Brasília has emerged as the third most important financial center of Brazil. We document the recent dynamic of this territorial division of labor, with Rio’s specialization in insurance and Brasília’s dependence on government-owned banks. Finally, we show signs that Brazil’s financial center activities might be following an inverse U-shaped pattern whereby increasing geographical concentration is followed by its slow decline. Key Words: Brazil, concentration, financial centers, São Paulo, territorial division of labor.     

A Review of “Politics of Urban Runoff: Nature,Technology, and the Sustainable City”

California sage scrub (CSS) is a highly threatened vegetation community in coastal Southern California, 90 percent of which has been lost. Understanding CSS recovery is critical to its survival. This study compares long-term effects of grazing, cultivation, and mechanical disturbance in Southern California by tracking the extent of exotic grassland in two valleys in the Santa Monica Mountains over sixty years using aerial image analysis. Native shrubs returned to the grazed valley over one and one-half times faster than they did in the cultivated valley. Cultivation might result in a type conversion of CSS to exotic annual grassland that resembles a new steady state.     

Urban Pulse—The Struggle for Water,Life, and Dignity In South African Cities: The Case of Johannesburg

The struggle for water is a key feature of life in Johannesburg, as it is in all South African cities. This article describes a court action that was brought against the City of Johannesburg by the people of one neighborhood, Phiri, in an effort to secure an adequate supply of water. It is shown how the people of Phiri argued for the removal of discriminatory technology in the form of prepayment meters and for an increase in the quantity of water. Furthermore, it will show how race, class, and geography are articulated in the post-apartheid city.     

Placing the “Analyst” in Discourse Analysis: Iteration,Emergence and Dialogicality as Situated Process

Discourse analysis is a powerful and versatile methodological tool, informing a diverse body of critical geographic scholarship. Too often, however, discourse analysis remains unexplored, operating as a “black box,” underelaborated and hence undertheorized as to just what it offers. In this article, we articulate discourse analysis as inherently processual, by which we mean both that it should be understood as a process and that it can play an integral role throughout the research process. This article is derived from a meta-analysis of an exercise that invited early-career geographers to conduct discourse analysis on commentary centered on the 2013 U.S. federal government shutdown. The reflexive research process highlights the iterative, emergent, and dialogic properties of a processual engagement with a text. We suggest that recognizing these qualities enriches the role of both the analysis and the analyst(s) and expands the valence of discourse analysis as a productive and versatile component of critical human geography.     

Analysis of water consumption using a regional input–output model: Model development and application to Zhangye City,Northwestern China

Based on a regional input–output model, we developed a method to identify the relationships between production activities and the related water consumption, as well as the relationships established between different sectors concerning water resources (i.e. indirect consumption). This method is applied to Zhangye City, an arid area of northwestern China that is characterized by water shortages. Our results confirm that although Zhangye suffers from a serious water shortage, the city's economic structure is based on sectors that consume large quantities of water. On the one hand, food production and forestry consume large quantities of water, reflecting the large scale of these water-intensive forms of land use. On the other hand, the industrial and service sectors use a smaller amount of water directly in production, but to produce the intermediate inputs that they incorporate into their production processes, a high consumption of water is often necessary. At present, there is no evidence that the city alleviates its water scarcity by importing virtual water in the form of economic inputs produced in other regions, suggesting that planners should include both direct and indirect water consumption in their resource allocation planning.     

Reordering China,Respacing the World: Belt and Road Initiative (一带一路) as an Emergent Geopolitical Culture

Since it was set out in speeches by China’s Premier Xi Jinping in September and October 2013, discussion of the Belt and Road Initiative (BRI) has proliferated in China. We argue that the scale and density of this discussion can usefully be conceptualized as an emergent geopolitical culture, reworking geopolitical narratives and spatial policies established in China in the second half of the twentieth century. In charting this emergence, we examine the ways in which the BRI links the reordering of China’s economic geography with articulations of China and the world. Surveying BRI as an emergent geopolitical culture, we draw on the example of the narratives of familiarity, partnership, and location vis-à-vis China and Singapore. Our conclusions reflect on how the BRI is appropriated to visions of China’s destiny. Key Words: Belt and Road Initiative, China, geopolitical culture, Singapore.     

Groundwater flow regime under natural conditions as inferred from past evidence and contemporary field observations in a semi-arid basin: Cuenca de la Independencia,Guanajuato, México

This study was carried out in the Cuenca de la Independencia, a semi-arid basin in Central Mexico. The objective is to describe the main features of a groundwater flow regime under natural conditions, based on groundwater discharge manifestations. Information obtained from paleoecological, paleontological, archaeological and historical data suggests that, prior to heavy development (starting in the 1950s), the hydrogeologic regime was characterized by a larger groundwater availability in a more humid and colder climate. Manifestations associated to groundwater discharges are springs, lagoons, wetlands, saline soils, chalcedony deposits, phreatophytes, thermalism, and artesianism. The different types of manifestations and their position in the basin indicate the influence of groundwater flow systems hierarchically nested, forming concentric zones at ground level. The groundwater flow regime corresponds to a classical gravity-induced flow system with generation of local, intermediate and regional patterns. Integrating several types of data to establish the flow geometry and its dynamics has proven a useful tool to increase understanding of the original groundwater regimes. This approach can also be applied in other over-exploited semi-arid basins.
