“…The form of urban area development that occurs in the built area along the main road corridor has a tendency to form a concentration of urban activity and its focal point is characterized by the presence of a residential area, a shopping center, services, and economic activities that are compactly integrated. The rapid process of urbanization and suburbanization, ad hoc and unplanned spatial distribution and allocation of spatial activities will have an impact on decreasing environmental quality [67]. Differences between city centers and peripheral locations indicate that location plays at least some important roles, in combination with income and governance factors [68].…”

Metropolitan Urban Mamminasata South Sulawesi, Indonesia as the object of study is explored in the core-peripheral spatial interaction towards the formation of suburban service centers. The problems raised in this study are (i) is there a relationship/correlation between spatial integration, spatial interaction, and urban agglomeration to the formation of urban activity systems and (ii) how the formation of urban activity systems works as a determinant of economic growth, land use change and environmental quality degradation towards sustainable development in the metropolitan city of Mamminasata. Comparative studies of suburban areas have been carried out over three time periods (2001, 2015 and 2019). Data elaboration on observations, surveys and documentation is done to describe urban dynamics in terms of economic, social and environmental aspects. Path analysis is used to address direct effects, indirect effects, differences, and dependencies between urban elements. The gravity model is used to analyze the spatial interactions of the core city with the periphery. The study results show that spatial integration, spatial interaction and urban agglomeration have a positive effect on the system of urban activity and economic growth in the outskirts of the Mamminasata Metropolitan area. The results of this study recommend policy makers and urban planners that land use change, spatial integration and urban spatial interactions on the spatial scale of metropolitan cities to require the implementation of sustainable development concepts oriented towards saving the environment, ensuring fairness in economic access and creating social cohesion, in line with meeting national Metropolitan city development targets by 2030.

“…It is apparent from the regression results shown in Tables 3 and 4 that both the size and proportion of migrant populations have a statistically significant negative relationship with AQI, indicating that urban atmospheric pollution will be abated with an increase in the size or proportion of migrant populations in urban districts. Moreover, the migrant populations will generally mitigate the deterioration of urban air quality because in contrast to native residents, migrants' activities, for example, their usage of cars, is of lower intensity (Yang, 2017), which moderates the overall impact of urban residents on environmental pollutant emissions (Cramer, 1998;Squalli, 2009Squalli, , 2010Price and Feldmeyer, 2012;Ma and Hofmann, 2019). In addition, low income levels within migrant populations also lead to lower energy consumption of these residents compared with the energy consumption of local residents, as confirmed by data in the Survey Report on China's Floating Population and Squalli (2009).…”

“…Nevertheless, there is widespread consensus that the relationship between populations and environments is complicated (United Nations Population Fund, 1991;Qin, 2009). Some studies have shown that migration has little or no effect on pollution levels in terms of air quality (Squalli, 2009;2010) because migrants typically have smaller ecological footprints than locals, producing less pollution (Cramer, 1998;Hunter, 2000;Neumayer, 2006;Bohon et al, 2008;Price and Feldmeyer, 2012;Ma and Hofmann, 2019). Cramer (1998) who investigated the relationship between population growth and air quality in the United States, found that higher concentrations of migrant populations corresponded to lower levels of five major air pollutants.…”

In recent years, researchers have devoted considerable attention to identifying the causes of urban environmental pollution. To determine whether migrant populations significantly affect urban environments, we examined the relationship between urban environmental pollutant emissions and migrant populations at the prefectural level using data obtained for 90 Chinese cities evidencing net in-migration. By dividing the permanent populations of these cities into natives and migrants in relation to the population structure, we constructed an improved Stochastic Impacts by Regression on Population, Affluence and Technology model (STIRPAT) that included not only environmental pollutant emission variables but also variables on the cities' attributes. We subsequently conducted detailed analyses of the results of the models to assess the impacts of natives and migrants on environmental pollutant emissions. The main findings of our study were as follows: 1) Migrant populations have significant impacts on environmental emissions both in terms of their size and concentration. Specifically, migrant populations have negative impacts on Air Quality Index (AQI) as well as PM 2.5 emissions and positive impacts on emissions of NO 2 and CO 2 . 2) The impacts of migrant populations on urban environmental pollutant emissions were 8 to 30 times weaker than that of local populations. 3) Urban environmental pollutant emissions in different cities differ significantly according to variations in the industrial structures, public transportation facilities, and population densities.

“…Furthermore, the adaptation process, carried out by the local community, towards infiltrative migrants involved the provision of accommodation in a residential environment and their willingness to build mutually beneficial cooperation. Hence, it is important for the population to understand population-environmental relations (Ma and Hofmann, 2019). Information from the field showed that mutual acceptance among communities possesses the capacity to strengthen social relations, leading to welfare improvement.…”

The rapid development observed in metropolitan cities affects the spatial interaction between regions and urban cluster settlements, leading to the fiscal growth of suburbs. This study is therefore, aimed to examine and analyze the spatial integration, urban agglomeration, economic growth and formation of the social territorial structures in the Mamminasata Metropolitan suburb using a combination of qualitative and quantitative approaches. Meanwhile, data were obtained through observation, surveys and documentation studies. Furthermore, the results showed that an elevation in the pattern of urban activities elicited changes parameters assessed which lead to economic growth in the suburbs of Mamminasata Metropolitan. This finding further indicated that spatial integration an urban agglomeration and the increase of activity, led to land tenure inequality and differences in adaptation between migrants and the local community. However, changes in spatial use influenced the structure and pattern of space, therefore, causing the formation of social territorial structures in the area.
