Patterns of Built-Up Area Change in Small Cities of West Sumatra Province - Indonesia

Abstract

West Sumatra Province has many small cities considered by population size as well as their built-up area. In these cities, a vast paddy field landscape still exists as a prominent characteristic. However, there are varied patterns of built-up area change among the cities. This paper examines the patterns of changes over the past 13 years from 2005 to 2018 using spatial metrics method. The measurements consist of the number of patches, patch density, mean patch size, and Urban Sprawl Index. Patterns of built-up area change generated by combining such measurements. It is found that the relationship between spatial geometry measures and growth rate measure is weak. Therefore, the study suggests identifying trends and comparisons among cities with the same characteristics to interpret spatial metrics method appropriately. The study also shows three types of built-up area change: (a) infilling with low-density development, (b) edge expansion with low-density development, and (c) edge expansion with scattered/leapfrogging development. The development of cities in the first and second types had a compact pattern, while the third tended to develop fragmented.

Is urban sprawl a threat to sustainable development? A review of characteristics and consequences

“…Uncontrolled urban growth is also associated with negative expansion and urban sprawl (Ghosh, 2019;Shao et al, 2020). While urban agglomeration is a highly developed spatial form of integrated cities (Fang & Yu, 2017), urban sprawl mostly occurred in lower densities accompanied by expansion of urban periphery, is acknowledged as the opposite force, with its character of scattered and leapfrogging development (Mills 1981;Brueckner & Fansler 1983;Lowry, 1988;Hayden, 2004;Downs, 1999;Ewing, 2008;Ahyuni & Nur, 2020). Though urban sprawl is a global phenomenon, but it is always viewed in different ways on how and why it was resulted (Hosseini & Hajilou, 2019;Abulibdeh et al, 2019).…”
