Abstract
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.
Highlights
Urban sprawl has been observed throughout the world, and there is concern about its impact on peri-urban areas (PUAs) [1,2,3]
We studied the spatiotemporal changes of land use and land cover (LULC) of the Arshaly district, which is within the PUA of the fast-growing metropolis Nur-Sultan
The following observations were made: there was a significant increase in arable land and a decrease in pasture land; the area of water bodies varied within the seasons, but no general trend of their increase or decrease was found; a steady increase in the area occupied by forest stands was noted; and the most active increase in built-up territories was observed on the border of the Arshaly district with the capital of the republic
Summary
Urban sprawl has been observed throughout the world, and there is concern about its impact on peri-urban areas (PUAs) [1,2,3]. It has been established that the growth and development of a large city and its interaction with the PUA are influenced by three main factors: economic development, the intensity of trade growth, and political motivation on the part of the state aimed at the growth and development of cities [4]. Over the past 20 years (1998–2018), the capital of Kazakhstan transformed from a provincial regional city into a large metropolis as a result of the combined impact of the above three factors and became the political, economic, and cultural center of the republic [5]. In the adjacent agro-industrial areas, under the influence of the metropolis, certain changes took place during the study period, both under the influence of urban sprawl [6] and other factors [7], which still require analysis and evaluation
