Papers in Environmental Protection Agency. Change 22(1), 5566 (2012). If the null hypothesis is rejected, the fixed effects model will be selected for further inferences. Gregory D. Urban Sprawl and Uneven The mixed evidence demonstrates the complex interplay between urban form and air pollution, which further implies that the inconsistent relationship may exist in cities at different urbanization levels and over different periods33. Stone, B. Jr. Urban sprawl and air quality in large US cities. It will be beneficial to further polish this study by including other important controlling factors, such as vehicle possession. Glob. Plant trees and incorporate the care of city green spaces as a key element in urban planning. Landscape Shape Index (LSI) indicates the divergence of the shape of a landscape patch that increases as the landscape becomes increasingly disaggregated68. Popul. and JavaScript. Current numbers for natural increase/decrease and migration flows come from population estimates for 2014, the most comparable year to the ACS data because it is the midpoint of the combined ACS data used in this chapter. Urban administrative restructuring, changing scale relations and local economic development in China. & Kho, Y. GeoDa: an introduction to spatial data analysis. J. Transit Cooperative Research Program, Transportation Research Board. Int. Low-density residential units may mean different things in the city of Houston . Computer simulation results also indicate that more compact cities improve urban air quality but are under the premise that mixed land use should be presented18. Policy Responses. Fang, C., Liu, H., Li, G., Sun, D. & Miao, Z. Estimating the impact of urbanization on air quality in China using spatial regression models. Results demonstrate that the urban form evolution has long-term effects on PM 2.5 level, but the dominant factors shift over the urbanization stages: area metrics play a role in PM 2.5 trends of . Once there were green fields: How urban sprawl is undermining America's of Planning Education and Research 25, Urban sprawl makes it difficult for people from different areas to participate in the democracy of our country. One reason recreation-based counties grew was that they had a net gain of new residents who moved from other U.S counties, the only rural county type to have a gain in net domestic migration. Read more on how this ranking was calculated. Smart growth and urban development pattern: a comparative study. Luo, Y. et al. 40(10), 17431758 (2006). 185, 189200 (2017). Zhou, B., Rybski, D. & Kropp, J. P. The role of city size and urban form in the surface urban heat island. Liu, Y., Wu, J., Yu, D. & Ma, Q. Int. Ashgate Press, 2008). CAS As a result, in each county type, adults ages 65 and older now make up a larger share of the total population than in 2000. Henderson, J.V., Logan, J.R. & Choi, S. Growth of China's medium-size cities. Aggregation metrics measure the spatial compactness of urban land, which affects pollutant diffusion and dilution. Dynamic effect analysis of meteorological conditions on air pollution: a case study from Beijing. & Ou, J. Report 231K13001 (Environmental Protection Agency, Washington, 2013). CONTIG_MN is another method of assessing patch shape based on the spatial connectedness or contiguity of cells within a patch. volume10, Articlenumber:18618 (2020) Health damages from air pollution in China. Tsai, For example, between 1950 and 1995, the population of Chicago grew by 48 percent, while land coverage increased by 165 percent (Openlands Project, 1998). One of the biggest drivers of urban sprawl is the demand for low-cost housing, and the planning of these developments often neglects long-term social externalities. Population Change and Its Driving Factors in Rural, Suburban, and Urban The estimated coefficients vary substantially. PubMed Central All those regions have a strong economy and higher population density86. These relate to the economic well-being of their residents. Environ. Based on the above observations, how urban form affects within-city PM2.5 level changes may differ over the urbanization stages. Eastern China is generally wealthier than the interior, resulting from closeness to coastlines and the Open-Door Policy favoring coastal regions. ADS Thus, an overlooked yet essential task is to account for various levels of cities, ranging from large metropolitan areas to less extensive urban area, in the analysis. Growth at the fringe: The influence of political fragmentation in United States Our Built and Natural Environments: A Technical Review of the Interactions Between Land Use, Transportation and Environmental Quality (2nd edn.). https://doi.org/10.1016/S0065-308X(05)62004-0 (2006). To inform stakeholders making transportation decisions, we created a set of metrics analyzing transportation equity for neighborhoods which we approximate with census block groups within four metropolitan regions: Baltimore, Maryland; Lansing, Michigan; Nashville, Tennessee; and Seattle, Washington. Chem. When stratified by spatial autocorrelation relationship (Fig. Journal of Economic Perspectives 18, 177-200 (2004). While 20th century segregation was also residential Black urban areas versus white suburban areas in the 21st century we're seeing segregation as more regional today. https://doi.org/10.7927/H4GT5K3V. The rising per capita income due to the concentration of manufacturing industrial activities can deteriorate air quality and vice versa if the stronger economy is the outcome of the concentration of less polluting high-tech industries.

New York's Grand Central Station overflows with a sea of commuters and travelers at rush hour. The estimation equation for the panel data model in this study is given as: where the subscript \(i\) and \(t\) refer to city and year respectively. The development of urban sprawl increases the need for transport and reduces the land available for agriculture. Since 2000, more people left rural counties for urban, suburban or small metro counties than moved in from those areas. If compact urban development does not contribute to a rising proportion of green areas, then such a development does not help mitigating air pollution41. ed. Larger contiguous patches will result in larger CONTIG_MN. These negative consequences of sprawl must be counterbalanced with the widely-held notion that this type of development pattern provides relatively affordable housing opportunities and a seemingly higher quality of life. We're also seeing white suburbs and Black suburbs. How American racism is rooted in residential segregation Many factors can influence the regional air quality, including emissions, meteorology, and physicochemical transformations. A dwelling located in a rural area is preferred by 14% of respondents and living in the city centre is the least preferred option (12%). Factors that may affect urban driving include: Traffic density More one-way streets More pedestrians More cars on the road Slow or irregular traffic More potholes More construction zones Factors that may affect suburban driving include: More school zones and crosswalks Lower speed limits School buses Remote Sens. Nonetheless, two aggregation metrics, LSI and AI, play positive roles in determining the PM2.5 trends in the Central model. Solutions Combat poverty by promoting economic development and job creation. Elliot, D. et al. Every day, 1.3 million commuters travel into Manhattan to work for the day and then return to their homes at night. It has been criticized for its numerous negative effects on the environment, social life, and economy of cities and the countries they reside in. 9, 918. https://doi.org/10.3390/rs9090918 (2017). Influence of urbanization on air quality based on the occurrence of particle-associated polycyclic aromatic hydrocarbons in a tropical semiarid area (Fortaleza-CE, Brazil). Fourth, the factors have varying effects on population change from rural to suburban to urban areas. This increases the risk of transporting dangerous substances and the risk of importing food that is not produced to the high standards required in the United States and other developed countries. Poor air and water quality, insufficient water availability, waste-disposal problems, and high energy consumption are exacerbated by the increasing population density and demands of urban environments. After excluding cities with invalid or missing PM2.5 or sociodemographic value, a total of 626 cities, with 278 prefecture-level cities and 348 county-level cities, were selected. China Dimensions Data Collection: China Administrative Regions GIS Data: 1:1M, County Level, 1 July 1990. Relationship between air pollutants and economic development of the provincial capital cities in China during the past decade. Results demonstrate that the urban form evolution has long-term effects on PM2.5 level, but the dominant factors shift over the urbanization stages: area metrics play a role in PM2.5 trends of small-sized cities at the early urban development stage, whereas aggregation metrics determine such trends mostly in mid-sized cities. Finally, all pixels falling inside of the city boundary were averaged to represent the overall meteorological condition of each city. Res. Powered by WordPress / Academica WordPress Theme by WPZOOM. Environ. Appl. All authors reviewed the manuscript. It is becoming a major issue in many cities around the United States. Environ. In addition to the three major demographic shifts that are reshaping urban, suburban and rural counties in the U.S. the aging of the population, changing racial and ethnic makeup and the influx of new immigrants there are significant differences in other important metrics across community types.

An, exclusion-inclusion framework for extracting human settlements in rapidly developing regions of China from Landsat images. York, R., Rosa, E. A. Sci. 120, 443455 (2018). When combined with effective transportation networks, it promotes social integration and reduces pollution. Some factors appear to affect population change more in one area than in others. (2000). 5. Google Scholar. We suggest that, depending on the citys developmental stage, different aspects of the urban form should be emphasized to achieve long-term clean air goals. The impact of urban development on air quality and energy use. & Wang, S. J. The compact city: a sustainable urban form, 200211 (1996).
