Authority over Forests: Empowerment and Subordination in Senegal's Democratic Decentralization

Senegal's 1998 forestry code transfers rights to control and allocate forest access to elected rural councils, ostensibly giving the elected authorities significant material powers with respect to which they can represent the rural population. But the Forest Service is unwilling to allow rural councils to exercise these powers. To retain control, foresters use pressure, bribes and threats while taking advantage of the inability of the rural representatives to influence actors higher up in government. They justify themselves with arguments of national good and local incompetence. The foresters ally with urban‐based forest merchants and are supported by the sub‐prefect. Despite the transfer of forest rights, the foresters continue to allocate access to lucrative forest opportunities — in this case charcoal production and exchange — to the merchants. Despite holding effective property rights over forest, such as the right to exclude others, rural councils remain marginal and rural populations remain destitute. The councils cannot represent their populations and therefore cannot gain legitimacy: they have no authority. Despite progressive new laws, the Forest Service helps to maintain Senegal's healthy urban charcoal oligopsonies, while beating back fledgling local democracy.     

URBAN CLUSTERS AS GROWTH FOCI*

ABSTRACT Urban clusters are geographic concentrations of urban places, some of which may include major cities. Unlike agglomerations, whose geographic boundaries are clearly delineated, urban clusters have “variable” boundaries, with each urban settlement being part of its “own” cluster of populated places, located within its commuting range. As our study indicates, the effect of clustering on urban growth is not uniform: it appears to be positive in low density clusters, and negative in densely populated ones. In particular, outside densely populated areas, towns surrounded by other localities tend to evince higher rates of population growth than their “lone” counterparts.     

DELINEATING METROPOLITAN AREAS USING LAND PRICES*

ABSTRACT This paper proposes an approach to delineating metropolitan areas that is more general than the standard approaches in three respects: First, it uses the fraction of land prices attributable to economies of urban agglomeration instead of using commuting intensities as an indicator of economic integration between metropolitan centers and their hinterlands. Second, it identifies metropolitan centers endogenously instead of determining them exogenously. And third, it takes metropolitan subcenters explicitly into account. An empirical illustration is used to show that the approach tends to delineate fewer but larger metropolitan areas in densely populated regions, and smaller metropolitan areas in sparsely populated regions.     

The Magnetic Field Model Applied to Swedish Settlements

To study the reason for changes in the population of urban settlements and sparsely populated districts we need an approach on a regional geographic level that will combine various theoretical elements and which, taken together, will provide an interdisciplinary platform. The identity of a place is created by specific local factors as well as by social and economic processes occurring both in the place itself and in the urban system. We can use indications showing how local and regional urban systems function in order to ascertain why one urban settlement grows while another stagnates, why a sparsely populated district in one region flourishes while other districts languish. Using the decision-making point of view adopted by households and businesses will help us to achieve our aim.
The starting point of the model employed—called the magnetic field model—is the fact that an attraction field of positive factors forms in and around places with a growing population. The aim of this paper is to show that a regional geographic analysis can be made from a number of indicators of significance for the development of populations in urban settlements and sparsely populated districts. Naturally these indicators can—and should—be queried, added to and assessed when other, similar investigations are carried out.     

Seismic Damage to Structures in the 2015 Nepal Earthquake Sequences

The 7.8 Mw Gorkha earthquake struck the east of Lamjung in Nepal, followed by a sequence of powerful aftershocks. Chinese Team Six including the authors inspected the seismic damage to civil structures along 10 paths in densely populated areas with a seismic intensity of VII to IX, 40 days after the main shock. The damage was categorized according to structure types and described in detail. Several conclusions are made: powerful aftershocks can significantly affect the failure patterns; geological conditions, structure types, and height have great influence on the level of damage; and the local risky retrofitting technique needs improvement badly.     

How much does urban location matter for growth?

This paper analyses the effect of location characteristics on urban growth using regression cubic splines. Our empirical analysis shows that in Spain, differences in accessibility to major urban centres and geographic isolation help explain differences in population growth rates across municipalities between 2001 and 2014. Moreover, even though physical proximity to large cities is usually assumed to be closely related to the attractiveness of a municipality, we found that urban population growth is even more related to the joint effect of distance to major centres and agglomeration. In this respect, there seems to be a threshold from which agglomeration diseconomies come into play such that a greater proximity to major cities and/or being localized within a more densely populated area goes against local growth.     

Spatial Diffusion of the HIV/AIDS Epidemic: Modeling Implications and Case Study of AIDS Incidence in Ohio

This paper extends a compartmental epidemiological model for HIV transmission and AIDS incidence to include hierarchical and expansion spatial diffusion. An implication of the resultant model is that hierarchical diffusion causes the large infection growth rates of densely populated areas at the top of the central places hierarchy to “chain” down and dominate small local growth rates during the exponential-growth phase of the epidemic. Also, hierarchical diffusion causes a high transient growth rate in the first few years of a local epidemic. The spatial compartmental model fits observed AIDS incidence spatial diffusion patterns in Ohio reasonably well.     

Of squatting amid capitalism on Yangon's industrial periphery

Across major cities throughout the world, inflated real-estate markets continue to exacerbate crises of affordable housing. Amid such conditions, squatting has emerged as a means to claim urban residence while bypassing the rule of property, resulting in densely populated informal settlements stretched along urban peripheries, most notably in the Global South. But in what respect might squatting be said to have anti-capitalist content? But does the challenge squatting poses to private property mean the practice is unambiguously anti-capitalist? The case presented here illustrates how squatting – initially a challenge to the rule of private property – becomes imbricated with wider relations of extraction and rule and with the broader capitalist context more generally.

民族餐馆是餐饮服务业的特殊形式，认识其行业性质及文化特性是理解民族餐馆空间分布的关键。本研究以郑州、开封和洛阳为案例，从市场区位选择、文化邻近、城市格局等多个维度，对城市民族餐馆分布进行了探索性分析。研究发现，城市民族餐馆分布在空间分布结构上呈等级扩散分布，其集聚核心大多位于城市传统商业服务业中心；商圈、大学、医院等人口密集区，是城市民族餐馆市场选择的重要区位。民族餐馆与城市商圈具有较高的空间重合度，与大学、医院等区位要素空间关系因城而异。商圈周边布局民族餐馆的概率较高；城市民族餐馆在少数民族居住生活区域高度集中，民族商业文化传统对民族餐馆分布具有向心集聚作用。本研究认为城市民族餐馆分布取决于城市发展格局、市场区位选择及文化邻近的综合作用，民族餐馆的分布概率因城市规模大小、区位地点差异及空间尺度而发生变化。     

Trace Metal Distribution Within Marine and Estuarine Sediments of Western Moreton Bay,Queensland, Australia: Relation to Land Use and Setting

This broad‐scale investigation provides an overview of trace metal concentration and distribution within sediments in the subtropical setting of Moreton Bay on the eastern Australian coast. Samples of sediment in one‐metre long PVC cores were collected from the intertidal zone of the western shoreline of the Bay and within its main estuaries. The material is typically silty sand along the Bay shoreline, becoming more clayey within the estuaries. Downcore pH is typically between 7.0 and 8.0, with layers in some cores of pH 6.0 to 7.0. Locally, pH can fall below 5.0 due to pyrite oxidation or exceed 8.0 due to the presence of shell fragments. A comparison with results of similar studies in other highly populated centres in Australia shows that overall the Moreton Bay area sediments have relatively low metal content. Typically, concentrations are two to three times higher in fine‐grained, estuarine sediments than in sandy material along the Bay shoreline. Compared with Australian and New Zealand Environment and Conservation Council Guidelines for metal concentrations in sediments, the elements most commonly elevated and warranting further assessment are Ni, Hg, Pb, Zn, and occasionally Cd, As and Cr. The highest metal concentrations are found in estuaries, close to more populated or industrialised areas, notably along the Brisbane River. Overall, the distribution of metals in unconsolidated material is controlled by (a) the heavy metal affinity for Fe‐ and Mn‐rich oxidised sediments, (b) grain size, (c) background concentrations in local rocks, and (d) conditions of weathering and deposition. For example, natural elevation of Fe occurs in marine sediments adjacent to areas of Tertiary basalts and this has produced a relative increase in a number of trace metals in those sediments. Typically, trace metals correlate well with Al, and with Fe and Mn oxyhydroxides. The results of this study show that in the western Moreton Bay region, natural controls have the major influence over metal distribution; although urban and industrial inputs exist, for much of the area they are secondary. The main sources of introduced trace metals are presumed to be light industry (such as maritime and port facilities, petroleum refineries and storage, manufacturing and chemical processes), landfills, agriculture and intensive fertilising (for example, golf courses) as well as the composite effect of urban centres. Overall, higher concentrations of metals are closely related to intense development. If specific locations are targeted for focussed sampling, elevated concentrations of metals are likely to be found locally.     

Public works and municipal government in two Italian capital cities: Comparing technical bureaucracies in Turin and Rome, 1848-88

The article draws a comparison between nineteenth-century Turin and Rome, linking the growth of technical bureaucracies in the municipal institutions of both cities to the local struggles for control over urban space. In both post-1848 Turin and post-1870 Rome, the implementation of new institutional reforms offered local city councils an opportunity to gain more power and autonomy than they had enjoyed in the recent past. The organization and the role of municipal technical services were therefore affected, with quite opposite results, by the conflicts opened with the state about the redefinition of the province of local government     

Cost Efficiency,Urban Patterns and Population Density When Providing Public Infrastructure: A Stochastic Frontier Approach

Relying on stochastic frontier analysis we propose a methodology to study the technological characteristics and cost efficiency levels related to the provision of public infrastructure for basic utilities. The methodology assumes a cost minimizing behaviour on the part of public officials when planning the construction of local infrastructure, which is represented by way of a flexible translog cost function. Introducing relevant definitions of scale economies, associated with larger numbers of inhabitants and dwellings, as well as economies of density, brought about by reductions in urban dispersion, we analytically determine the optimal population densities for which average cost is minimized. We illustrate our model with the water cycle sector, including water distribution, sewage collection and cleansing of wastewater, and considering data at the municipality level for the Spanish region of Castilla y León. The obtained results indicate potential cost savings in the form of decreasing average costs, as relevant scale and density economies are present, along with large inefficiency levels. Relevant policy guidelines favouring larger and denser urban sizes are drawn, as the observed cost excess is the result of a general suboptimal urban size in terms of population density, and the negative effects of dispersed settlement patterns.     

Localization of Business Services in European Regions: Large Urban Areas Stand Out

The recent increase in business services in terms of both value added and employment has had a positive effect on regional economies, helping them to create a comparative advantage and contributing to the general development of regional productive systems. This heterogeneous set of activities is characterized, among others, by its uneven distribution in the territory. In this paper we aim to identify the key factors that influence the location of business services within the NUTS 2 regions of the European Union. Using a multivariate analytical approach (combining a principal components factor analysis and a multiple linear regression by means of ordinary least squares), four key factors have been identified. In terms of their influence on the location of business services, we can pinpoint the following factors: urban dimension, competitiveness, accessibility and economic dynamism. It was found that business services tend to locate in urban, densely populated and dynamic areas with high levels of competitiveness and easy access.     

Urban revitalization in the Netherlands: Current trends versus actual policies

The paper focuses at the discrepancy between actual urban policies and current spatial socio‐economic developments. Three discrepancies are discussed: homogeneous concepts versus developments directed at heterogeneity; economic seduction policies versus comprehensive developments; and small‐scale policies versus higher level developments. Basic to the current spatial trends is the evolution of a large‐scale urban network. This results in a less hierarchical urban structure and a heterogenization of economic centres and living areas which occurs both within and between urban places. Because of this, the steering possibilities of hierarchic organized urban policies are hampered. In contrast to these developments, urban policy in the Netherlands has a hierarchical nature and focuses heavily on the traditional dominant urban nodes. The present phase of policy, ‘urban management’, illustrates this. An adaption of the spatial framework of policy is needed. The paper also shows that present policies haue a too narrow economic perspective which leads to an underestimation of present and future problems related to the labour and housing market. A plea is made for an explicit dynamic approach to urban revitalization in which the normative and instrumental function is stressed. Moreover, the suggested distinction between efficiency and equity is rejected The article is based on a survey of current trends and future research needs under the authority of the Advisory Council for the Programming of Future Directions in Spatial Research in the Netherlands.     

Services in Russia: past,present, and future

In spite of ambitious modernization plans of the government, structural change in Russia is not proceeding in the direction of highly developed economies. Part of the lag in the tertiarization process can be explained by the fact that, as during the Soviet period, the role of services in the economy is still ignored, particularly regarding innovation. This paper aims to contribute to the analysis of the evolution of services in Russia since the mid-1990s and its future prospects by compiling data from the World Bank, the International Labor Organization, Rosstat, and the World Input–Output Database. Two complementary and novel perspectives are adopted: a production system perspective and a spatial perspective. Regarding services in the Russian production system, comparison of interindustry linkages reveals that, in addition to traditional relevant activities like wholesale/retail trade and transport and communications, business services are acquiring great importance as production process inputs. Concerning the spatial perspective, we observe a greater presence of non-market services in less densely populated federal districts, while strategic service activities are highly concentrated in the most dynamic ones. Analysis of major Russian cities confirmed the trend of business services concentrating in densely populated and highly innovative cities. In brief, services, and in particular business services, can be a means to boost innovation and growth in Russia, but more attention from political leaders is necessary for these activities. The modernization process should abandon its current “high-technology industry myopia” and take into consideration the innovative, and especially, the knowledge-diffuser role, that services can exert.     

New Globalism, New Urbanism: Gentrification as Global Urban Strategy

This paper uses several events in New York in the late 1990s to launch two central arguments about the changing relationship between neoliberal urbanism and so–called globalization. First, much as the neoliberal state becomes a consummate agent of—rather than a regulator of—the market, the new revanchist urbanism that replaces liberal urban policy in cities of the advanced capitalist world increasingly expresses the impulses of capitalist production rather than social reproduction. As globalization bespeaks a rescaling of the global, the scale of the urban is recast. The true global cities may be the rapidly growing metropolitan economies of Asia, Latin America, and (to a lesser extent) Africa, as much as the command centers of Europe, North America and Japan. Second, the process of gentrification, which initially emerged as a sporadic, quaint, and local anomaly in the housing markets of some command–center cities, is now thoroughly generalized as an urban strategy that takes over from liberal urban policy. No longer isolated or restricted to Europe, North America, or Oceania, the impulse behind gentrification is now generalized; its incidence is global, and it is densely connected into the circuits of global capital and cultural circulation. What connects these two arguments is the shift from an urban scale defined according to the conditions of social reproduction to one in which the investment of productive capital holds definitive precedence.     

The wellsprings of candidate emergence: Geographic origins of statewide candidacies in the United States

Candidates and nominees for statewide office in the United States do not emerge from random locations within states. In this paper, we argue that densely populated areas are more likely to both foster political ambition and to afford the resources that enable candidates to wage an effective campaign. Candidates and nominees for major statewide office originate from populous counties in numbers significantly out of proportion to these counties’ share of their state’s population. Meanwhile, aspirants virtually never emerge out of rural areas or small towns. The pattern holds for all candidates and nominees for both Senate and governor and for both major political parties. Regional biases are more pronounced for institutionally strong gubernatorial offices than for weak offices and among high quality nominees for statewide office than among inexperienced candidates. Given the importance of urban/rural cleavages in the American electorate, these findings raise fundamental questions about political representation.     

Spatial-temporal trends in complementary and alternative medicine (CAM) offices in Ontario,Canada

This paper assesses complementary and alternative medicine (CAM) from a spatial-temporal perspective; it would be of particular interest to those who evaluate health care resource accessibility over space. The analysis compares CAM supply (number of offices, employment, and sales) in Ontario by provincial district, metropolitan influence classification, and health care and social assistance employment quintiles using summary statistics, Kruskal-Wallis and median analyses, and local spatial autocorrelation evaluation. Metropolitan areas throughout Ontario, but especially in the southcentral part of the province, are well endowed with CAM supply and tend to be most important in terms of CAM change. CAM offices are increasing in size in the most populated parts of the province and shrinking in regions that are more peripheral. CAM supply per capita is highest in census subdivisions with moderate levels of health care and social assistance employment, a result that is not offset by significant temporal change. While CAM supply is restructuring in many of Ontario's most populated urban locations, the overall attraction of CAM resources to large and small metropolitan areas is clear. If current spatial-temporal trends continue, CAM spatial disparities will be exacerbated as accessibility to CAM in Ontario's most peripheral locations worsen.     

Congestion Tolling and Urban Spatial Structure

According to the standard model of urban traffic congestion and urbanspatial structure, congestion tolling results in a more concentrated city. In recent years, a new model of rush-hour urban auto congestion has been developed that incorporates trip-timing decisions—the bottleneck model. In the simplest bottleneck model optimal congestion tolling without toll-revenue redistribution has no effect on trip price because the efficiency gainsexactly equal the toll revenue collected. Optimal congestion tolling then has no effect on urban spatial structure. This paper formalizes and extends this result.     

Evaluating the efficiency of museums using multiple outputs: evidence from a regional system of museums in Spain

Data Envelopment Analysis is used to evaluate museum efficiency. This approach enables us to create a relative efficiency measure for each museum, taking into account resources used by museums and the performance of their activities based on four well-defined tasks: conservation, research, communication and exhibition. Empirical analysis of data from a regional museum system in Spain is performed, considering a complex production function with several inputs and outputs. The main findings indicate that at least half the museums chosen operate efficiently, with the major cause for inefficiency being inadequate resource management. Only few museums evidenced significant inadequate scaling problems. Major progress, mainly due to improvements in internal efficiency, is evident in the museum system ratios when analysing productivity evolution using the Malmquist Index. By contrast, technological change has less impact, proving that cultural heritage is less receptive to new technologies as compared to other cultural industries.
