Modelling urban expansion in the transitional Greater Mekong Region

Abstract

Urban expansion in emerging urban areas has drawn plenty of attention. The Greater Mekong Region (GMR) has experienced dramatic urbanisation and urban land expansion in recent decades. Based on built-up area data from the World Bank compiled over the 2000–2010 period, this paper integrates geographical, socioeconomic and physical factors to explore the underlying patterns and dynamics of urban land expansion in the GMR. An explicit and critical emphasis is placed on institutional conditions. The growth of built-up areas in the GMR has concentrated heavily in the capital cities and coastal areas. Additionally, the transitional countries have shown more dramatic expansion. The results of multi-level models suggest that urban developments in the GMR are not only sensitive to local contexts, such as distance to coastlines, accessibility factors and population growth rates, but are also closely associated with country-level factors, such as country political systems, and patterns of economic growth and foreign investment. We also find that the demographic measures of urbanisation have more influence in Thailand, while measures of economic growth have more marked impacts in the transitional countries.

The peri-urbanization of Europe: A systematic review of a multifaceted process

“…While this review has analysed peri-urbanization processes in Europe, different co-occurring processes in peri-urban areas are also reported in case studies from other parts of the world. As an example, a review of studies for the Mekong region also found broad variation in patterns of changing urban growth and socioeconomic contexts, differentiated by local and national policies (Li, Wei, & Korinek, 2018), while in China, different spatiotemporal growth patterns were reported alongside socioeconomic changes such as access to education, clean water, urban green space and mobile phone use (Tong, Hu, Frazier, & Liu, 2017). This suggests that the multifaceted process of peri-urbanization is not a strictly European process, but instead a more generic phenomenon that manifests itself in multiple world regions.…”

Beyond the bid‐rent: Two tales of land use transition in contemporary China

“…The main determinant of urban land development, according to the bid‐rent theory, has been widely recognized as the distance to the city center (Alonso, 1964; Bourne, 1976). Although scholars in the field of macroeconomics have explained the accumulated outcome of urban sprawl with the help of the bid‐rent approach (Li, Wei, & Korinek, 2018). This is, as Wu (2002) argued, a simplified theoretical deduction.…”

Natural Geography and Patterns of Local Population Growth and Decline in Spain: 1960–2011

“…They include variables for slope, temperature, precipitation, groundwater availability, distance to ports, and agricultural land suitability and find significant negative relations of urban growth with distance to ports and heating degree month (defined as the total number of degrees below 18 • C summed across the month of the year). Li et al [11], in a recent study, modeled urban expansion in the Greater Mekong Region in Southeast Asia at the county level between 2000 and 2010 and tested for five geographic indicators. They did not find a significant coefficient for slope and elevation, while annual average precipitation, distance to coast, and a Mekong River Basin dummy showed a negative effect on urban expansion.…”
