Environmental Impact Analysis of Methane Gas from Landfill using LCA in Klotok landfill, Kediri, East Java

The effective management of municipal solid waste is a persistent challenge within emerging nations. The observed phenomenon can be attributed to a multitude of reasons, encompassing swift economic growth, urban population development, garbage output, the substantial costs associated with waste treatment, and the design and functionality of containment systems. Methane, being the second most significant greenhouse gas following carbon dioxide, is prominently emitted into the environment by municipal solid waste dumps. This study use the IPCC model to assess the methane emissions generated by landfills. Additionally, Simapro 9.5 software is utilised in conjunction with the ReCiPe 2016 Midpoint approach to evaluate the corresponding environmental consequences. The Klotok landfill was found to generate the maximum quantity of methane, specifically 3.518 Mg CO2 eq, as determined by the composition analysis of paper waste. Additionally, the largest environmental impact was observed in the category of human toxicity carcinogenicity, as indicated by the life cycle assessment (LCA) analysis with a value of 3733.057.

Responses of applied voltages on the archaea microbial distribution in sludge digestion

As the development of urban population led to the increase of domestic water consumption, consequently the generation of surplus sludge (SS) produced increasingly during sewage treatment processes. In order to enhance the SS resource utilization efficiency, an electricity-assisted anaerobic digestion (EAAD) system was employed to examine the alterations in the digestion broth and the characteristics of gas production. Additionally, the response of applied voltages on the distribution of archaeal community near various electrodes within the sludge was explored. The results revealed that the application of high voltages exceeding 3.0 V hindered the CH4 production but stimulated the CO2 generation. Subsequently, both CH4 and CO2 production were impeded by the applied voltages. Furthermore, the increased voltages significantly decreased the abundance of Methanomicrobia, Methanosaeta, and Methanosarcina, which were crucial determinants of CH4 content in biogas. Notably, the excessively high voltages intensities caused the AD process to halt and even inactivate the microbial flora. Interestingly, the distribution characteristics of archaeal community were influenced not only by the voltages intensity but also exhibited variations between the anode and cathode regions. Moreover, as the applied voltage intensified, the discrepancy of responses between the cathode and anode regions became more pronounced, offering novel theoretical and technical foundations for the advancement of electricity-assisted with AD technology.

Dynamics of development of urban housing stock and urban population

The development of urban housing policies needs to be correlated with the demographic development of the city. Demographic dynamics in the world, including Kyrgyzstan, is developing towards the urbanization of the population and the increase in agglomerations. Therefore, in this article, we study the degree of interdependence of urban population growth factors with the dynamics of the housing stock and the volume of commissioning of a new urban dwelling. In particular, the two largest cities of the Kyrgyz Republic were studied – the capital Bishkek and the southern city of Osh, in which more than 60% of the urban population concentrated. On the basis of the analysis, the aim is to establish a unified public housing and demographic policy for cities based on the mutual development of the urban population and urban housing stock. We have considered the historical development of these factors as well with subsequent justification of their prospective or prognostic development in the light of one housing and demographic policy for the strategic urban development plan. On the demographic side, we took indicators of the total permanent urban population and the dynamics of population growth in Bishkek and Osh; on the housing side, we took indicators of commissioning new urban housing, urban housing stock and the availability of housing per person in the city.

Spatio-temporal Coupling Analysis of Population Urbanization and Economic Development in Yangtze River Delta Urban Agglomeration

Population urbanization and economic development are highly correlated, and the degree of coordination between the two has gradually become one of the important issues for the healthy development of the region. With the advancement of high-quality integration in the Yangtze River Delta, it is particularly important to clarify the coupling and coordination process and spatial differentiation between population urbanization and economic development for the future integration and sustainable development of the Yangtze River Delta region. Given this, we establish a comprehensive evaluation index system of population urbanization and economic development based on the period of 2009–2020. Taking the Yangtze River Delta urban agglomeration as the research object, the entropy method and the coupling coordination model are used to carry out Spatio-temporal coupling analysis. The results show that (1) the level of population urbanization and economic development of the Yangtze River Delta urban agglomeration is continuously rising, while economic development lags behind population urbanization development, and the economic development level needs to be further improved. The degree of coupling coordination of population urbanization and economic development has continued to increase, and the synergistic development effect of the two has been improved, (2) the comprehensive level of population urbanization and economic development of each city in the Yangtze River Delta urban agglomeration shows an obvious inter-regional unbalanced development trend, and (3) there is an obvious polarization in the coupling coordination level between population urbanization and economic development in the Yangtze River Delta urban agglomeration.

Spatial Pattern of Underground Space Development in Major Cities in China: Evaluation and Analysis

Underground space development has gradually become an organic part of China’s urban development and construction. Comprehensively developing underground space scientifically and rationally to give full play to its comprehensive benefits is the main problem faced by China’s underground space development at this stage. This research starts with the measurement of the level of urban underground space (UUS) development. This paper constructs a UUS development level measurement indicator system, which is composed of Construction of UUS (D1), urban economic development indicators (D2), and urban population development indicators (D3), which has 12 secondary indicators, and then we use entropy-TOPSIS method to quantitatively evaluate the development level of underground public space in 39 prefecture-level cities and above in my country and analyze its spatial differentiation. The results show that the urban agglomeration has the characteristics of “high-high” cluster distribution with the development level of underground space. However, the overall level of underground space development in China’s major cities is not high and there are apparent differences in the level of UUS development. In terms of spatial distribution, the sustainable development level of cities in the eastern coastal regions of China is relatively high, with towns in the central and northeastern areas ranking second and western towns and northeastern cities ranking the lowest. At the same time, we found that there is a mismatch between the underground space development index and the economic population development index in the evaluation index. Finally, some suggestions are put forward to realize the balanced development of UUS development in our country.

Regional Development Quality of Yangtze River Delta: From the Perspective of Urban Population Agglomeration and Ecological Efficiency Coordination

With the deepening of the development process of regional integration in the Yangtze River Delta, integration and high quality have become the key paths of regional development. On the basis of the panel data of 26 cities in the Yangtze River Delta urban agglomeration, from 2008 to 2018, this paper uses a DEA model to calculate the ecological efficiency of each city. On the basis of the visual expression of the population agglomeration degree, with the help of ArcGIS platform, the coupling coordination between the population agglomeration and the ecological efficiency is calculated by using the coupling degree model. The results show the spatiotemporal pattern changes of the coupling coordination degrees of 26 cities in the Yangtze River Delta urban agglomeration between population agglomeration and ecological environment, modeling the impact of urban population growth on the ecological environment. The research provides a scientific basis for determining the goal of urban population development, for coordinating the relationship between populations and the environment in urban development, and for realizing regional sustainable and high-quality development.

Optimization of Diagrid Angle for High Rise Structure for Varying Bay Widths

The development of urban population, the lack of space and the high land costs has created the scope and necessity for the high-rise structures. In high rise structures, the design of lateral load resisting systems is more crucial than gravity load resisting system. There are many structural systems exists in literature to resist lateral loads. Diagrid structure is one among them which is proven to be both structurally and architecturally efficient structural system to resist lateral loads. The present study aims to investigate the best bay spacing for a particular high-rise structure and also optimizing the best diagrid angle to suit to the selected bay spacing. A numerical study is carried out with a 24 storied high-rise structure of plan area 36m x 36m considering with and without corner columns. The structure performance is checked with a bay width of 4m and with a bay width of 6m. Each structure is analyzed for four angles of inclinations of diagrid are formed by connecting 1, 2, 3, 4 stories respectively to optimize the diagrid angle. A comparative investigation is carried out for the structural responses like storey displacement, storey drift and base shear with different diagrid angles and with different bay width.

Multiscale analysis of the correlation patterns between the urban population and construction land in China

The relationship between the urban population and urban construction land is an important indicator for assessing urbanization quality. With the rapid growth of urban population and the drastic expansion of urban construction land, human-land contradictions have become a major factor restricting the sustainable development of cities. This paper analyzes the coordination relationship between the urban population and urban construction land at the national, provincial and provincial-capital scales in China in recent years. The results show that the expansion rate of urban construction land in China is generally faster than the growth rate of the urban population, resulting in an overall discordant human-land relationship. Although the regional differences in the uncoordinated allocation of urban population and urban expansion gradually narrowed from 2010–2017, there was still mismatch among provinces. The relationship between the urban population and urban construction land trends was mainly coordinated at the provincial scale and uncoordinated at the provincial capital scale. By combining the coordination degrees at the provincial and provincial-capital scales, we identify six combined development types and analyze the combined characteristics of urban population growth and urban construction land expansion. It is necessary to formulate differentiated policies to guide urban population development and urban construction land use at different scales. These findings provide a theoretical basis for alleviating the human-land contradiction and achieving sustainable urban development.

What drives urban population growth and shrinkage in postsocialist East Germany?

AbstractMost cities in East Germany experienced drastic shrinkage between 1990 and 2014, but in recent years some have stabilized or even switched toward new growth paths, while others have been continuously declining. A descriptive analysis of subgroups of cities with diverging population growth trajectories reveals that this recent phase of “urban resurgence” accounts to a large share to the growth of the largest cities and some smaller cities in their hinterland and is strongly related to the residential preferences of families and young adults. Furthermore, the estimation of spatial regression models for the period 2004–2014 including a comprehensive set of control variables, such as agglomeration effects, initial demographic conditions, labor market characteristics, climate, and quality of life‐related factors, reveals that recent patterns of urban population development are negatively correlated to historical growth rates during times of socialism. This indicates that postsocialist urban development can be interpreted as a direct outcome of the transition process and as a backlash against the socialist past when urban development was dominated by central planning policies. However, the relevance of the individual determinants included in our regression model differs strongly with respect to the population dynamics in different age groups.

Exploring the Interactive Development between Population Urbanization and Land Urbanization: Evidence from Chongqing, China (1998–2016)

To promote regional sustainable urbanization strategies, this paper selected the population and land resources in the urbanization system, and used the time series-based econometric analysis method and the coordinated development degree model to empirically study the interactive relationship between population urbanization (PU) and land urbanization (LU) in Chongqing, China, from 1998 to 2016. The research results showed that: (1) The development of urbanization in Chongqing was relatively rapid, but the level of development was relatively insufficient. The phenomenon of population outflow during urban development was more serious, and the structure of land use irrational; (2) There was a long-term cointegration relationship between PU and LU; PU is the Granger cause of LU. A PU increase of 1% in the short-term will promote LU by 3.29%, and in the long-term will promote 2.28%; the contribution of population agglomeration to urbanization is more than 80%, while land expansion is only about 20%, and the urban development model, which relies on urban land expansion is not applicable; (3) LU was faster than PU, but the improvement of PU development’s quality level was greater than that of LU. The development quality of both systems increased year by year, and gradually developed into a coordinated state. It is recommended that the government strengthen land planning, delineate urban growth boundaries, and increase the level of land intensive use; furthermore, through the reformation of the land finance and the household registration systems, a system for linking population, finance, and construction land should be established to promote the coordinated development of the two systems.

Urban Population Development in Germany (2000-2014): The Contribution of Migration by Age and Citizenship to Reurbanisation

The increase of the population of large German cities between 2000 and 2014 indicates a reurbanisation process in line with the concept of the “growing city”. This exploratory investigation will analyse the influence of internal and external migration on the population development of the German urban system by applying descriptive and statistical methods, going beyond the mere observation of selected cities.
 This paper shows that reurbanisation in Germany has resulted from various age- and citizenship-dependent combinations of spatial population movements, which in turn express different location advantages and disadvantages. The structural change towards a knowledge economy, the expansion of education, and changing living concepts on the demand versus new urbanistic planning concepts on the supply side strengthen the affinity of different population groups for urban living. This new attractiveness of cities seems to be most distinct among young adults’ motives for living in cities or not. Furthermore, the dynamics of these processes are also dependent upon conditions on the national and international levels. Thus, before the economic and financial crisis 2009 the balances of internal migration of the German as well as foreign population had a decisive influence on the dynamics, in-migration surpluses from abroad rose considerably after 2009. With the rising numbers of asylum seekers, state-controlled residence allocations as well as migrant networks are increasingly important for the population development of cities. At the same time, especially in cities with at least 500,000 inhabitants, ongoing growth is creating shortages on the housing and real estate markets, which tend to counteract the population growth.

Study on water resources optimal regulation of inter-basin water transfer project

Water resources optimal regulation is an important means to mitigate the shortage of water resources and promote social and economic sustainable development in regions or watershed. With the rapid development of urban population and industrial and agricultural production in recent years, the shortage of water is becoming more and more serious in Jiaodong area. The four regions with serious water shortage including Weifang, Qingdao, Yantai and Weihai in Jiaodong area are the typical research areas. In combination with the water transfer project of Yellow river to Qingdao and the south-to-north water transfer project, the water diversion is carried out to alleviate the contradiction between water supply and demand of Jiaodong area. The year of 2014 deemed as the base year and the years of 2020 and 2025 are the planning years. Based on the supply and demand analysis of water resources, an optimal regulation model is built with the minimum total water shortage considering the constraints of water supply capacity of project, water distribution capacity and minimum water supply of bleeds and so on. The optimal regulation schemes are obtained by solution model using MATLAB programming. The results show that water shortage rate of the four cities decreases significantly in annual regulation. For different planning years, guarantee rate of 50%, 75% and 95%,the total water shortage rate will be reduced by 15.35%、15.75% and 16.85% respectively in 2020, and in 2025the total water shortage rate will be reduced by 13.27%、13.26% and 14.19% respectively. Therefore the water resources optimal regulation of inter-basin water transfer project can effectively mitigate water scarcity and the contradiction between water supply and demand in Jiaodong area.

Industrial area as a basis for spatial optimization of land use in Kiev

In article deals with problem of using the urban land, including land under the industrial objects in Kiev. Also was analysed the ways of optimization the urban land using. Today become particularly acute the problem for efficient use of urban land use, including land for industrial facilities non-functioning as a reserve future development of Kyiv-based ecological-economic approach to solving them. However, to ensure sustainable development of urban population (preserve and improve health, improve working conditions, improve living conditions, increase the construction of social and affordable housing, reducing unemployment, creating new jobs, improving the ecological state of the environment) within large cities , you need to identify ways to optimize existing urban land use. The complexity of management decisions is determined, above all, the fact that in most cities of Ukraine territorial resources are exhausted and vacant land plots require significant investment. Also, a significant proportion of non-functioning industrial enterprises, which occupy large areas in the city were in Kyiv surrounded by residential development, buffer zones, technogenic disturbed and contaminated land. These objects be removed outside the settlements and the land on which they are to be re-cultivated and restoration for more ecological, economically feasible and sustainable use. The rapid development of large cities around the world and increase their impact on the environment and society is accompanied by a set ekonominyh, environmental and social issues that significantly influence the development of land relations in settlements in general. Today in Kyiv observed the changing dynamics of land area, which is to reduce the share of agricultural and forestry purposes and to increase the territory of other categories. The process of de-industrialization and suburbanization of urban land use is inevitable. They in turn accelerate other processes - "crowding out" of industrial facilities in the cities suburbs, which in turn will foster a number of ecological, economic and social problems. Management processes of territorial development of the city can be successful only when decisions on current issues of land use based on strategic, long-term development programs, offensive planning ideas zemleohoronnyh ensure consistency of implementation measures. Optimization of territorial development. Kyiv is to improve the structure of the land to improve the efficiency and usage of urban land, improvement of investment attractiveness, increase their profitability, ensuring the sustainability of ecosystems city. In our belief improving ecological and economic situation of the city, forming an effective urban land may provide by moving industrial facilities beyond Kyiv, to reorganize these areas of balance and formation of the optimal structure of urban land. Given the shortage of available areas for further development of the city's new housing construction, facilities service sector, tourism, etc. Industrial areas in which rolled production function, should be seen as a spatial basis optimize land use in Kiev. Taking into account the economic, social and environmental factors optimizing industrial areas are not functioning businesses that occupy large areas of urban land should also consider the most expedient type of land use. This, in turn, will contribute to the growth of urban land use, improve the well-being of the urban population, increasing tax revenues to the city budget, city economic development and is a prerequisite for creating favorable conditions for attracting investments. Keywords : urbanization, deindustrialization, industrial objects, industrial area, urban land use, land resources.

INFLUENCE OF MIGRATORY PROCESSES ON FORMATION OF URBAN POPULATION IN KRASNOYARSKY KRAI IN 1954 – 1984

Migration is the overriding factor of formation of the population of reclaimed territories and a significant factor in urban population development. In the second half of the XX th century the active migrations directed from the west to the east and back and from the village to the city were detected. In Krasnoyarsky Krai inflow of migrants was one of the biggest in the country, however, the number of those leaving the city was almost as high as the number of those arriving, which formed a negative attitude to migration as the cause of lumpenization of urban environment. The thesis proved in the article is migrations have become a source of urban development and defined urban social environment. Despite the migration flows on the territory of the region had a transit character, a certain part of migrants settled in the cities and became permanent residents. Although natives from the Siberian villages were the most numerous group, it was migrants from the European part of Russia who defined the quality of the population. Small non industrial towns lost their population as well as villages. The low level of urban amenities provision together with the growing demands of the population who already adopted urban way of life caused the migration outflow of in 1970s and 1980s which could not be compensated by migration inflow from the countryside.

Difficulties and Strategies in the Process of Population Urbanization: A Case Study in Chongqing of China

The population urbanization is one of the main routes and objectives of current Chinese urbanization. This paper, a case study in Chongqing, China, based on statistical data analysis and the forecasting of population growth trend, combined with the development law of population urbanization and regional reality, mainly discusses major problems facing the development of China’s population urbanization, economic, social and institutional obstacles to the solution of these problems in the development of population urbanization, and effective ways to promote positive interactions between the population urbanization and the economy, society and space. The analysis reveals that in the process of the population urbanization, due to the large population base, large agricultural population, serious population aging problem and low level of education of population, China’s population urbanization development does not match with economic and social development in objective and pattern; there is a glaring contradiction in industrial upgrading, labor supply, the population migration and relocation. It is necessary to take corresponding strategies in the population urbanization, population management system, labor resources and elderly-care policies, human resource development and economic growth, surplus agricultural population migration and the urban-and-rural development, in order to solve these contradictions and find out real effective ways to achieve positive interaction between the population urbanization and the economic and social development.

Dari Ritual Ke Panggung Pertunjukan: Perkembangan Tari Dalam Kehidupan Masyarakat

There are three primary functions of dance in human life, i.e., for ritual,for personal entertainment, and for aesthetic presentation. All dance experts believe that oldest function of dance in human life is for ritual. Dance is needed on occasion of birth, circumcision, marriage, death, war, changes of moon and sickness. Bali is richest island of dance in Indonesia and known as paradise in world of arts. The Balinese dance ritual dances for gods, for spirits of ancestors, for religious seers, for human beings, and also for underworld spirits. Indonesia is rich in dance for personal entertainment, such as tayuban in Central and East Java, Jaipongan in West Java, gandrung in East Java, joget in Bali, ronggeng Melayu in Sumatera, etc. The development of urban population with sufficient income has influenced development of dance as aesthetic presentation, because urban people, categorized as cultural consumers, need some aesthetic entertainment for their leisure time. The best country in world whose amazing development of her dance as aesthetic presentation is United States of America and New York is widely known as the mecca of performing arts

Urban Population Development in Europe, 1991–2008: The Examples of Poland and the UK

AbstractAcross Europe, there is a complex mosaic of urban population development. Characterized by great diversity and heterogeneity, this development does not follow a common pattern and cannot be attributed to specific regional trends (e.g. Eastern or Western European geographic location, or post‐socialist, old industrial or developed capitalist economic models). In this article, we show how this mosaic can be explained, relating it to various driving forces and overarching processes. Using a multilevel approach and looking at the period 1991–2008, we identified various European city population growth or decline clusters; these indicated that urban population development does not necessarily follow strictly national lines. Further, we argue that similar clusters of growing and declining cities may occur within European countries as diverse as Poland and the UK. Overarching driving forces such as demographic change interfere with national specificity and the peculiarities of local settings. The most significant finding of this article is that overlapping driving forces currently lead in their interplay to diverging courses of urban population development on different spatial scales (and will probably continue to do so in future).RésuméL'évolution de la population urbaine en Europe se présente comme une mosaïque complexe. Caractérisée par une diversité et une hétérogénéitéélevées, elle n'obéit à aucun schéma commun et ne peut être attribuée à aucune tendance régionale précise (comme la situation géographique en Europe de l'Est ou de l'Ouest, ou bien les modèles économiques post‐socialistes, industriels anciens ou capitalistes développés). Il est possible d'expliquer cette mosaïque en la reliant à divers facteurs moteurs et processus dominants. Une approche à plusieurs niveaux et l'étude de la période 1991–2008 permettent d'identifier différents pôles de croissance et de déclin de la population dans les villes européennes. Ceux‐ci indiquent que la population urbaine ne suit pas forcément les tendances nationales. En outre, des pôles similaires de villes en croissance et en déclin peuvent exister dans des pays aussi distincts que la Pologne et le Royaume‐Uni. Les dynamiques dominantes, telles que les changements démographiques, interfèrent avec la spécificité nationale et les particularités des contextes locaux. La conclusion la plus importante de ce travail est que ces dynamiques superposées viennent se conjuguer pour créer, selon l'échelon spatial, des trajectoires distinctes d'évolution de la population urbaine (ce qu'elles continueront sans doute de faire à l'avenir).

Coordination Degree of Urban Population, Economy, Space, and Environment in Shenyang Since 1990

In the background of China's rapid urbanization, the conflicts between urban population, economy, space, and environment are intensified and complicated. This article aims to establish a coordinate assessment method for studying urban population, economy, space, and environment interactions in city scale by principal component analysis and regression analysis. On the basis of the case study on Shenyang city, the results indicated that the integrated development of urban population, economic, and space was in a poor situation from 1993 to 1999, whereas it turned better after 2000, and the urban environment improved steadily after 1998. The static coordination degree of urban integrated development and environment showed obvious periodical and fluctuant characteristics. Compared with the static coordination degree, the dynamic coordination degree appeared to be smooth and lag. The static coordination degree was elementary discoordinative in 1993, 1994, and 1999; whereas it turned to be elementary coordinative between 1995 and 2005. The dynamic coordination degree was elementary discoordinative from 1993 to 1996, whereas it became elementary coordinative overall after 1997.
