Quasi Experiment

Fertility is a spatially non-stationary property of regional demographic systems. Despite the wealth of quantitative (micro–macro) information delineating short-term population dynamics in advanced economies, the contribution of economic downturns to local fertility has still been under-investigated along urban–rural gradients, especially in low-fertility contexts. Recent studies have assumed suburban fertility rates as systematically higher than urban and rural fertility rates. This assumption (hereafter known as the “suburban fertility hypothesis”) has been grounded on stylized facts and spatial regularities in advanced economies that reflect a significant role of both macro (contextual) and micro (behavioral) factors that positively influence fertility in suburban locations. To test the suburban fertility hypothesis at the macro-scale, the present study compares gross fertility rates from seven regional units of the Athens metropolitan area between 1991 and 2018. A refined spatial analysis of gross fertility rates during an economic expansion (1999–2008) and recession (2009–2018) was carried out in 115 urban, suburban, and rural municipalities of the same area. Experiencing sequential waves of economic expansion and recession, Athens’ socio-demographic dynamics were considered a sort of “quasi-experiment” for Southern Europe, linking late suburbanization with the multiple impacts of (rapid) economic downturns. Compared with both urban and rural locations, a higher fertility rate in suburban municipalities (15–20 km away from downtown Athens) was observed during the study period. However, a subtle distinction was observed during the economic expansion versus the recession. In the first period, the highest birth rates were recorded in industrial locations west of Athens, hosting economically disadvantaged communities with a relatively young population structure. With the recession, the highest fertility was associated with residential and service-specialized (wealthier) locations east of Athens, attracting resident population from neighboring areas, and better responding to crisis. The results of our study document how recent urban expansion and economic downturns have intrinsically shaped fertility dynamics, with implications for urban sustainability and social cohesion of metropolitan regions.

Economic Downturns

Between the 1970s and the 1990s, cities in Southern Europe experienced a progressive delocalisation of population, settlements and activities over larger regions. Economic downturns have increasingly influenced more recent waves of metropolitan growth, shaping differentiated patterns of urban change. While some cities evolved towards accelerated population dynamics in central districts responding to re-urbanisation impulses, other agglomerations were intrinsically bounded in a sort of ‘late suburbanisation’, with demographic shrinkage of both inner districts and rural areas, and uneven expansion of suburban population. By providing a comprehensive interpretation of the socioeconomic mechanisms underlying recent urban expansion, this study illustrates a diachronic analysis of population dynamics over multiple spatial scales and time frames in a metropolitan region of Southern Europe (Athens, Greece) between 1999 and 2019. Natural population balance was investigated vis à vis selected territorial indicators using descriptive, inferential and multivariate statistics. Results of the analysis identify different social forces underlying suburban population growth during economic expansion (2000s) and recession (2010s), evidencing a distinctive response of local communities to economic downturns that depends mostly on the background context (affluent versus disadvantaged neighbourhoods). Given the multiplicity of territorial dimensions involved in urban growth, our findings highlight how economic downturns distinctively shape metropolitan development based on locally differentiated demographic dynamics.

Area Expansion

Monitoring uncontained built-up area expansion remains a complex challenge for the development and implementation of a sustainable planning system. In this regard, proper planning requires accurate monitoring tools and up-to-date information on rapid territorial transformations. The purpose of the study was to assess built-up area expansion, comparing two freely available and widely used datasets, respectively, Corine Land Cover and Landsat, to each other, as well as the ground truth, with the goal of identifying the most cost-effective and reliable tool. The analysis was based on the largest post-socialist city in the European Union, the capital of Romania, Bucharest, and its neighboring Ilfov County, from 1990 to 2018. This study generally represents a new approach to measuring the process of urban expansion, offering insights about the strengths and limitations of the two datasets through a multi-level territorial perspective. The results point out discrepancies between the datasets, both at the macro-scale level and at the administrative unit’s level. On the macro-scale level, despite the noticeable differences, the two datasets revealed the spatiotemporal magnitude of the expansion of the built-up area and can be a useful tool for supporting the decision-making process. On the smaller territorial scale, detailed comparative analyses through five case-studies were conducted, indicating that, if used alone, limitations on the information that can be derived from the datasets would lead to inaccuracies, thus significantly limiting their potential to be used in the development of enforceable regulation in urban planning.

Despite limitations of low fertility and high acidity of the soils, the cerrado flora is the richest amongst savannas. Many cerrado woody species show sclerophyllous leaves, which might be related to the availability of water and nutrients in the soil. To better understand the function and structure of cerrado vegetation within its own variations, we compared two cerrado communities: one in its core region in central Brazil (Brasília, DF) and the other on its southern periphery (Itirapina, SP). We contrasted the length of the dry season, soil fertility rates, leaf concentrations of N, P, K, Ca and Mg and the specific leaf area (SLA) between these communities. The dry season was shorter on the periphery, where the soil was more fertile although more acidic. Plants from the periphery showed higher SLA and higher leaf concentrations of N, P, Ca and Mg. We propose that the higher SLA of plants from the periphery is related to the shorter dry season, which allows better conditions for nutrient uptake.

Increasing development is historically associated with fertility declines. However, demographic paradigms disagree about whether that relationship should hold at very high levels of development. Using national-level data through 2005, Myrskylä, Kohler, and Billari (2009) found that very high levels of the Human Development Index (HDI) were associated with increasing total fertility rates (TFR). This paper updates that finding with data up to 2017. It investigates whether the observed association has continued to hold for the countries originally studied and whether it holds for countries that have more recently reached very high HDI. For countries that reached HDI ≥ 0.8 in 2000 or before (n=27), the data indicate no clear relationship between changes in HDI and TFR at HDI ≥ 0.8. There is also no clear relationship for countries that reached HDI ≥ 0.8 between 2001 and 2010 (n=13). For countries that reached HDI ≥ 0.8 in 2000 or before, there appear to have been notable increases in TFR between 2000 and 2010, but those gains appear to have completely reversed between 2010 and 2017. The past finding of TFR increases at very high levels of development has not borne out in recent years. In fact, TFRs declined markedly in very high development countries between 2010 and 2017. This paper contributes to the debate over the relationship between development and fertility. That debate has an important bearing on how low fertility is conceived by social scientists and policymakers.

There has been much debate over the micro-level relationship between employment situations and fertility in Europe and Northern America. However, related research in East Asia is scant, although countries in this region have some of the lowest fertility rates in the world. Moreover, most studies analyze the employment-fertility relationship from a static perspective and only for women, which underemphasizes life-course dynamics and gender heterogeneity of employment careers and their fertility implications. Drawing on retrospective data from the 2017 Taiwan Social Change Survey (TSCS), this study explores women’s and men’s career trajectories between ages 18 and 40 in Taiwan using sequence cluster analyses. It also examines how career variations associate with different timing and quantum of birth. Empirical results show that economically inactive women experience faster motherhood transitions and have more children by age 40 than women with stable full-time careers. For men, having an unstable career associates with slower fatherhood transitions and a lower number of children. For both genders, self-employed people are the earliest in parenthood transitions and have the highest number of children by midlife. Our findings demonstrate sharp gender contrasts in employment careers and their diversified fertility implications in low-fertility Taiwan

Suburbanization of Bekasi Regency as a part of the Jakarta Metropolitan Area (JMA) is mainly induced by urban expansion and industrialization, in which the suburbanization process threatens food security and ultimately disrupts urban sustainability. This study aims to characterize industrial-dominated suburban formation to manage the suburbanization process using a quantitative zoning method. In assessing the characteristics of industrially dominated suburban, this research utilizes the concept of urban–rural development (URD), which consists of five aspects of development (socioeconomic, population, industrial, land-use, and environmental). Factor analysis and Rustiadi’s spatial clustering form regional clusters using all variables while referring to the URD concept. The results showed that there are three regional typologies: (i) urban, (ii) Desakota, and (iii) rural regions. Urban regions are situated in the central and western parts of Bekasi Regency, rural regions are situated in the northern part of Bekasi Regency, while the desakota region is situated between urban and rural regions. Characteristics of each typology then could be used as the basis for development policy in Bekasi Regency which is then constructed towards the protection of agricultural areas in the rural and desakota regions, serving both food security function and strengthening urban sustainability of JMA.

The Impact

Rapid urbanization has become a major urban sustainability concern due to environmental impacts, such as the development of urban heat island (UHI) and the reduction of urban security states. To date, most research on urban sustainability development has focused on dynamic change monitoring or UHI state characterization, while there is little literature on UHI change analysis. In addition, there has been little research on the impact of land use and land cover changes (LULCCs) on UHI, especially simulates future trends of LULCCs, UHI change, and dynamic relationship of LULCCs and UHI. The purpose of this research is to design a remote sensing-based framework that investigates and analyzes how the LULCCs in the process of urbanization affected thermal environment. In order to assess and predict the impact of LULCCs on urban heat environment, multitemporal remotely sensed data from 1986 to 2016 were selected as source data, and Geographic Information System (GIS) methods such as the CA-Markov model were employed to construct the proposed framework. The results showed that (1) there has been a substantial strength of urban expansion during the 40-year study period, (2) the farthest distance urban center of gravity moves from north-northeast (NEE) to west-southwest (WSW) direction, (3) the dominate temperature was middle level, sub-high level, and high level in the research area, (4) there was a higher changing frequency and range from east to west, and (5) there was a significant negative correlation between land surface temperature and vegetation and significant positive correlation between temperature and human settlement.

Abstract In Europe, falling fertility rates are regarded as part of a second demographic transition precipitated by changing values. Low fertility rates in developed Asian countries, however, are thought to be due to decreasing marriage rates, as a result of worsening young men’s employment. This study proposes the hypothesis that men in non-regular employment – those with low incomes and those who are unemployed – have lower probabilities of getting married. Male employment was analyzed using a logistic regression of micro data for 20- to 49-year-old men in Japan, South Korea, Singapore, the UK, France, and Sweden. The study’s findings generally supported the hypothesis and clearly confirmed that there is a relationship between employment and marriage in Asian countries, and especially in Japan.

Spatial Temporal Analysis

In response to serious environmental and socio-cultural challenges brought about by fast urbanization, the concept of a sustainable city emphasizes the quality of life of urban residents, assuring the importance of parkland provision in urban development. Despite China’s fast urban expansion in recent decades, scant attention has been paid to the development pattern of urban parkland in China and its implications toward urban sustainability. Engaging official data from government sources, this study conducted a spatial-temporal analysis of urban parkland in China. Results support the overall fast increase of urban parkland provision in China with a clear regional disparity. Moreover, the shift of development momentum from the east to the west has been identified in the recent decade. The status of economic development, the progress of urbanization, and the level of urban development investments are identified as key influential factors influencing the temporal changes of urban parkland in China. With the increasing demand for urban parkland and its important role in ensuring urban sustainability, recommendations to improve urban park development in China are proposed, including integrating urban parkland in urban land use management with specific planning guidelines, establishing a dynamic urban parkland monitoring system, incorporating both national and regional policy frameworks catering for both national standards and regional preferences, and shifting urban development investments with more emphasis on urban maintenance expenditure.
