“…Transport accessibility is assumed to be the main driver of urbanization [74][75][76] and city extensions intothe PUA. Accessibility is usually assessed in terms of connecting the AOI to transportation infrastructure (roads, railways, and airways), which facilitate communication with the main metropolitan area.…”

A Spatiotemporal Assessment of Land Use and Land Cover Changes in Peri-Urban Areas: A Case Study of Arshaly District, Kazakhstan

In this study, the spatiotemporal dynamics of land use and land cover (LULC) were evaluated in the peri-urban area of the Arshaly district, which borders the capital of the Republic of Kazakhstan. Landsat multispectral images were used to study the changes in LULC. The analysis of LULC dynamics was carried out using supervised classification with a multi-temporal interval (1998, 2008, and 2018). During the study period, noticeable changes occurred in LULC. There was an increase in the area of arable land and forests and a reduction in the pastures. There was a sharp increase in the built-up area; that is, there was an intensification of land use through an increase in the share of arable land as well as the transformation of agricultural land for development. However, in general, the influence of urban sprawl in this peri-urban area has so far been accompanied by only a slight focus on its sustainable development.

“…Land is the physical base of urban expansion, and urban expansion requires a lot of land for construction. It has resulted in enormous problems, such as farmland loss [4], fragmentation [5], and urban sprawl [6]. Reasonable land supply is crucial to reduce these problems.…”

State-owned construction land is the dominant legal land source for construction in China and its supply influences urban expansion, house prices, and economic development, among other factors. Surprisingly, limited attention has been directly devoted to the spatiotemporal variation in land supply or the driving factors. This paper applied a centroid model and hotspot analysis, and created a newly increased construction land dependence-degree index (NCD) to present the spatiotemporal variations of China's construction land supply magnitude and pattern from 2003 to 2014, using land supply data from 339 cities. A two-way fixed effect model was introduced to reveal the influence of the socio-economic driving factors. The results showed that China's state-owned construction land supply area (CLSA) and newly increased construction land supply area (NCSA) both increased during the period from 2003 to 2014, the geographic centroid of CLSA and NCSA moved northwest. NCD showed an overall increasing trend, and hotspots with high NCD migrated from the east region to the west region and shifted from an "east hot and west cold" pattern in 2003 to an "east cold and west hot" pattern in 2014. The gross domestic product (GDP) has a U-shape effect on CLSA and NCD. The population, average annual wage of workers, and investment in fixed assets (fiv) have positive effects on CLSA, and fiv also has a positive effect on NCD. The increasing ratio of tertiary industry added value to secondary industry added value reduces CLSA and NCD, and the effects of state policies vary from year to year. Different land supply policies should be implemented for cities in different development stages.

“…Unplanned settlements (Figure 1) which were built out of the official governmental plans of GCMR are thought to accommodate between 12 and 17 million inhabitants, or about 40%-50% of Egypt's urban population and over 20% of total population in 2006 [2,3]. Despite 30 years of attempts by the government to limit unplanned growth around the GCMR, as it has been in most Egyptian cities and villages, unplanned settlements around the GCMR sheltered more than 7 million inhabitants in 1998 [4]. As of 2006, they were estimated to contain more than 65% of the population of GCMR (10.5 out of 16.2 million inhabitants), and the rate of population growth in these areas is higher than other cities averages, with an increase of 2% between 1996 and 2006 [5].…”

Abstract:The Greater Cairo Metropolitan Region (GCMR) in its seeking to sustainable development (SD) by the year of 2050 facing the serious challenge of around 65 percent of Cairenes live in unplanned settlements. In this respect, the authors examined the effect of urban characteristics of unplanned settlements on SD in the Egyptian context, focusing on the type of unplanned growth on agricultural land. The output of the analysis were fourfold. First of all, we provide a brief overview of previous research on the main types of unplanned settlements in GCMR and the sustainability definition according to the Egyptian context. Secondly, we had a discussion with the local government during our field survey in GCMR to determine the study samples, the main urban characteristics, and the sustainability evaluation criteria in the Egyptian context. Thirdly, through the comparative analysis and geographic information system (GIS), we examined how the character of urban development affected per capita four urban measures in a cross-section of two settlements, one represented the unplanned settlements and other as a comparative planned sample to determine the real gap. Finally, by using the evaluation matrix, the help and block items are estimated for each measure of urban characteristics, providing substantive evidence on how the four measures of urban characteristics have been affected by the urban sprawl.
