Abstract The land use for the deceased is not only for the dead but also for the living relatives. It competes with land use for living populations in urban areas through occupying a specific space of land. This article looks at this shared interest in humankind by mapping the land use for the deceased in the mid-twentieth century and modern Beijing and address the sustainability of future land use for dead in Beijing. Specifically, it clarifies the change of its area and location in the urban–regional structure and also considers the background factors. In the 1930s, the spatial distribution of cemeteries in the mid-twentieth century was mapped using the old topographic maps and also mainly using city government materials for modern times. A comparison of land use between the two periods shows that the spatial land use for the deceased continues to be the characteristics of traditional funeral values, Feng Shui philosophy, spatial separation of the dead, and the population, such as public cemeteries surrounding the built-up area. The city government reduced the pressure on land resources by encouraging land-saving burial such as undersea burial, which affects the value of funerals for citizens, resulting in an area of cemetery per urban population.

AbstractUrban areas are believed to affect temperature readings, thereby biasing the estimation of twentieth-century warming at regional to global scales. The precise effect of changes in the surroundings of meteorological stations, particularly gradual changes due to urban growth, is difficult to determine. In this paper, data from 10 temperature stations within 15 km of the city of Mainz (Germany) over a period of 842 days are examined to assess the connection between temperature and the properties of the station surroundings, considering (i) built/paved area surface coverage, (ii) population, and (iii) night light intensity. These properties were examined in circles with increasing radii from the stations to identify the most influential source areas. Daily maximum temperatures Tmax, as well as daily average temperatures, are shown to be significantly influenced by elevation and were adjusted before the analysis of anthropogenic surroundings, whereas daily minimum temperatures Tmin were not. Significant correlations (p < 0.1) between temperature and all examined properties of station surroundings up to 1000 m are found, but the effects are diminished at larger distance. Other factors, such as slope and topographic position (e.g., hollows), were important, especially to Tmin. Therefore, properties of station surroundings up to 1000 m from the stations are most suitable for the assessment of potential urban influence on Tmax and Tmin in the temperate zone of central Europe.

This paper seeks to provide a conceptual framework in which to examine the social practices of contemporary austerity programmes in urban areas, including how these relate to different conceptions of crisis. Of current theoretical interest is the apparent ease with which these austerity measures have been accepted by urban governing agents. In order to advance these understandings we follow the recent post-structuralist discourse theory ‘logics’ approach of Glynos and Howarth (2007), focusing on the relationship between hegemony, political and social logics, and the subject whose identificatory practices are key to understanding the form, nature and stability of discursive settlements. In such thinking it is not only the formation of discourses and the mobilisation of rhetoric that are of interest, but also the manner in which the subjects of austerity identify with these. Through such an approach we examine the case of the regeneration/economic development and planning policy area in the city government of Birmingham (UK). In conclusion, we argue that the logics approach is a useful framework through which to examine how austerity has been uncontested in a city government, and the dynamics of acquiescence in relation to broader hegemonic discursive formations.

Anthropogenic land use has led to the loss and fragmentation of native habitats and disruption to ecosystem processes, resulting in a decline in landscape connectivity and biodiversity. Here, in order to find the potentials of improvements in ecological connectivity, we provide a spatial analysis to present differences in ecological connectivity based on land cover maps and urban habitat maps in Suwon city, Republic of Korea. We generated two permeability maps for use in a network analysis, one being land cover and the other urban habitat, including a 5-km buffer area from the city boundary. We then determined the current-flow betweenness centrality (CFBC) for each map. Our results indicate that forests are typically the most highly connected areas in both maps. However, in the land cover map results, nearly all high-priority areas were in the mountainous region (CFBC value: 0.0100 ± 0.0028), but the urban habitat indicated that grasslands and rivers within the city also significantly contribute to connectivity (CFBC value: 0.0071 ± 0.0022). The CFBC maps developed here could be used as a reference when introducing green infrastructure in cities. Before establishing ecological networks for urban areas, future work should integrate the land use and ecological data of different administrative districts with continuous ecological connection.

The expansion of urban areas and the increase in the number of buildings and urbanization characteristics, such as roads, affect the meteorological environment in urban areas, resulting in weakened pollutant dispersion. First, this paper uses GIS (geographic information system) spatial analysis technology and landscape ecology analysis methods to analyze the dynamic changes in land cover and landscape patterns in Chengdu as a result of urban development. Second, the most appropriate WRF (Weather Research and Forecasting) model parameterization scheme is selected and screened. Land-use data from different development stages in the city are included in the model, and the wind speed and temperature results simulated using new and old land-use data (1980 and 2015) are evaluated and compared. Finally, the results of the numerical simulations by the WRF-Chem air quality model using new and old land-use data are coupled with 0.25° × 0.25°-resolution MEIC (Multi-resolution Emission Inventory for China) emission source data from Tsinghua University. The results of the sensitivity experiments using the WRF-Chem model for the city under different development conditions and during different periods are discussed. The meteorological conditions and pollution sources remained unchanged as the land-use data changed, which revealed the impact of urban land-use changes on the simulation results of PM2.5 atmospheric pollutants. The results show the following. (1) From 1980 to 2015, the land-use changes in Chengdu were obvious, and cultivated land exhibited the greatest changes, followed by forestland. Under the influence of urban land-use dynamics and human activities, both the richness and evenness of the landscape in Chengdu increased. (2) The microphysical scheme WSM3 (WRF Single–Moment 3 class) and land-surface scheme SLAB (5-layer diffusion scheme) were the most suitable for simulating temperatures and wind speeds in the WRF model. The wind speed and temperature simulation results using the 2015 land-use data were better than those using the 1980 land-use data when assessed according to the coincidence index and correlation coefficient. (3) The WRF-Chem simulation results obtained for PM2.5 using the 2015 land-use data were better than those obtained using the 1980 land-use data in terms of the correlation coefficient and standard deviation. The concentration of PM2.5 in urban areas was higher than that in the suburbs, and the concentration of PM2.5 was lower on Longquan Mountain in Chengdu than in the surrounding areas.

AbstractThis review examines three major books on the history of Bombay. Historians of the city have tended to focus primarily on the period before 1930; this tendency has seriously limited our understanding of the dramatic transformations that have taken place in Bombay over the course of the twentieth century. Each of the studies reviewed here devotes considerable attention to developments since the 1920s. Collectively these works make a significant contribution to the appreciation of such matters as working-class politics, the changing character of workers’ neighbourhoods, land use, urban planning, and the ways the city has been imagined and experienced by its citizens. At the same time, these works all shift their analytic frameworks as they approach more contemporary periods and this restricts the authors' ability to assess fully the character of urban change. This paper calls upon historians to continue to apply the tools of social history, particularly its reliance on close microcosmic studies of particular places and groups over long periods of time, as they try to bridge the gap between the early twentieth century and the later twentieth century. At the same time, it suggests that historians need to consider Gyan Prakash's view of cities as ‘patched-up societies’ whose entirety cannot be understood through single, linear models of change.

Background. The enrichment of lead (Pb) in a rapidly expanding urban environment is largely caused by industrial and anthropogenic activities. However, very few studies have come from sub-Sahara Africa as a whole, in spite of the increased rate of population, industrialization and urbanization in this region. The city of Onitsha is the commercial heartland of southeast Nigeria. Objectives. To determine the concentration of Pb in soils and sediments in Onitsha and the surrounding area and to identify the possible sources of Pb content in the environmental media. Methods. One hundred and sixty-two (162) samples (120 top and subsoils, and 42 stream and side drain sediments) were collected from the city of Onitsha, Nigeria to determine Pb concentrations, identify the main sources of Pb in this region, and determine its fate in soil and sediments using Pb isotopes. Thirty (30) 15 g clay fractions of soil and sediment samples, and a sample each of galena (from the Lower Benue Trough), coal and soot from vehicle exhaust and battery cells were collected from the city and analyzed for lead isotopes (Pb204, Pb206, Pb207 and Pb208) using ultra-trace inductively coupled plasma emission spectrometry. Results. The distribution and concentration of Pb in the soil of Onitsha was observed to be influenced by land use patterns with very elevated concentrations of Pb observed for mechanic and metal workshop samples (1444.3, 1067.5, 1048.1, 1730.5 and 580.5 ppm); active waste dump samples (448.4 and 311.9 ppm); and farmland and garden samples (366.2 ppm). The concentration of Pb in the sediments also showed varying elevated concentrations across locations, ranging from 45.7–540.1 ppm. A comparison with the control samples revealed that the Pb concentrations measured in the environmental media were several folds higher than that of the control. The Pb isotope analysis indicated that most of the Pb in environmental media was anthropogenic in origin and had been predominantly contributed by unsustainable environmental practices such as indiscriminate waste dumps, hydrocarbonbased products emissions, by-products from mechanical workshops that have been haphazardly constructed in the city, and industrial plants located within urban areas. Conclusions. The relatively higher concentrations of Pb in soils and sediments were found to be influenced by land use, as also observed in the Pb isotope readings, which will, over time, adversely affect environmental media and biota. Competing Interests. The authors declare no competing financial interests.

ABSTRAKSalah satu dampak dari proses pembangunan adalah pencemaran dan kerusakan lingkungan. Pertumbuhan penduduk yang pesat terutama di daerah perkotaan dengan perilaku membuang sampah yang tidak baik menyebabkan berbagai limbah yang harus diserap oleh lingkungan, terutama limbah domestik atau limbah rumah tangga. Komposisi sampah organik menempati persentase tertinggi hingga 57% di Kota Bandung, dimana limbah sisa makanan yang menempati urutan teratas yaitu sebesar 40%. Masyarakat dan pemerintah saja tidak cukup untuk mengatasi persoalan pengelolaan sampah. Keterlibatan dan partisipasi aktif perusahaan sebagai pihak swasta melalui kegiatan tanggung jawab sosial perusahaan dapat dilakukan melalui program-program yang mendukung pengolahan limbah organik berkelanjutan. Pengembangan program CSR yang baik pada suatu perusahaan sebaiknya dikaitakn dengan kebutuhan dan persoalan yang dihadapi masyarakat sekitar. Model Social Responsible Business Practice, merupakan salah satu jenis program yang bertujuan untuk mensejahterakan masyarakat, tapi juga memiliki korelasi positif dalam peningkatan produktivitas perusahaan secara operasional. Model praktik ini, memungkinkan aktivitas perusahaan yang salah satunya mencakup penyediaan fasilitas yang memenuhi tingkat keamanan dan keselamatan lingkungan dan dapat memelihara aktivitas pembangunan berkelanjutan. PT. Pertamina TBBM Bandung Group merupakan salah satu BUMN yang peduli dengan inovasi penanganan masalah sampah di Kota Bandung, melalui program BU MANIK (Budidaya Maggot dan Pupuk Organik), sejalan dengan program KANG PISMAN (Kurangi, Pisahkan, Manfaatkan) milik pemerintah Kota Bandung, yang bertujuan untuk membudidayakan maggot sebagai media utama pengurai limbah organik serta pakan ternak alami. Efektifitas program ini bergantung pada CSR PT. Pertamina TBBM Bandung Group sebagai lembaga yang memfasilitasi pelaksanaan program dan kelompok bank sampah sebagai komunitas yang diberdayakan, serta keterlibatan masyarakat dan dukungan pemerintah.Kata kunci: CSR, pengelolaan sampah, sumber daya berkelanjutan, pemberdayaan ABSTRACTOne of the impacts of the development process is environmental pollution and damage. Rapid population growth, especially in urban areas with bad waste disposal behavior, causes a variety of waste that must be absorbed by the environment, especially domestic waste or household waste. The composition of organic waste occupies the highest percentage up to 57% in the city of Bandung, where food waste that occupies the top rank is 40%. The community and the government alone are not enough to overcome the problem of waste management. The involvement and active participation of companies as private parties through corporate social responsibility activities can be done through programs that support sustainable organic waste treatment. The development of a good CSR program in a company should be related to the needs and problems faced by the surrounding community. Social Responsible Business Practice Model, is one type of program that aims to prosper the community, but also has a positive correlation in increasing company operational productivity. This practice model allows company activities, one of which includes the provision of facilities that meet the level of environmental security and safety and can maintain sustainable development activities. PT. Pertamina TBBM Bandung Group is one of the BUMN that is concerned with the innovation of handling waste problems in the city of Bandung, through the BU MANIK (Cultivating Maggot and Organic Fertilizer) program, in line with the KANG PISMAN program (Reduce, Separate, Utilize) the Bandung city government, which aims to cultivate maggot as the main media to decompose organic waste and natural animal feed. The effectiveness of this program depends on the CSR of PT. Pertamina TBBM Bandung Group as an institution that facilitates the implementation of programs and groups of waste banks as an empowered community; as well as community involvement and government support.Keywords: CSR, waste management, sustainable resource, empowerment

This article describes modernity in the city of Makassar during the New Order era. The meaning of modernity in this article was a modern idea or thought in the form projects of development (modernization) which the state tries to control. The control of the State is manifested in the form of uniformity and mobilization of development projects by the city government. The main impact that arises from the process is problems of urban, environment of the urban physical and social life of population of the city. This study uses the approach of the history of the city. The data used came from archives, newspapers, magazines, and results of interviews. This study shows that uniformity and mobilization of urban development modernity projects touch the lowest level, especially in the regulation and use of urban space and in the activities of urban residents. At the same time, the control and influence of the private sector increasingly determines the use of space. A predetermined city plan often can not work because it gets intervention from the interests of the private sector. In this conflict of interests, various "disappointments" arose in the attempt to modernize urban space. In urban areas, problems arise in structuring cities and social life which are vulnerable as an impact of an increasingly widespread modernization project. On the other side, the livelihood sources of some urban residents such as the informal sector are increasingly marginalized and have no support from the city government.
