Peri-urbanisation and loss of arable land in Kumasi Metropolis in three decades: Evidence from remote sensing image analysis

Evaluation of the environmental carrying capacity should be measured as part of sustainable land use planning. One of methods to evaluate this carrying capacity is land capability evaluation.. This study aims to evaluate the suitability of landuse in each of land capability classes in Mojokerto Regency. Land capability is obtained by spatial analysis and overlay of several criteria for land capability, included soil texture, effective soil depth, drainage, land slope, and soil erosion. The description of actual landuse is obtained using landsat 8 OLI images at coverage time in May 2018. The results of study show that the land capability in Mojokerto Regency varies from Class I to Class VIII. The actual land use in Mojokerto Regency are about 98% or 95314.33 Ha are suitable to the land capability, and 2% or of 2078.67 Ha are unsuitable to the land capability. Based on the environmental carrying capacity, about 78.85% or 76798.89 Ha of land in Mojokerto Regency are allocated accordingly, and 0.90% or of 875.29 Ha of land are allocated beyond their carrying capacity, 19.39% or 18884.18 Ha of land are allocated in a conditional manner so it needs any specific treatments of landuse.

“…Urbanization is one of the most evident global changes. During the last century, rapid urban growth exerted heavy pressure on land and resources in urban areas, as well as rural areas [1,2]. Large parts of the world are highly urbanized and the majority of the world's population now lives in cities and towns [3].…”

Influence of Urbanization Processes on the Dynamics and Scale of Spatial Transformations in the Mazowiecki Landscape Park

This paper explores how urbanization processes, since the 1950s, affected forested areas in the Mazowiecki Landscape Park and determines if these processes resulted in a significant reduction of forest. Spatial analyses, which were used to generate very detailed data on the area of forests, agricultural land, and development areas, were carried out, and the spatial directions of the changes were determined. The results indicate that, in comparison to the 1950s, in the 1990s, the forest area did not decrease, but, in fact, increased, despite a significant increase in the development area, both in the present area of the park and in its buffer zone. This was due to the fact that new buildings were constructed in mainly agricultural areas. At the same time, intensive afforestation of weak soils, mainly inland dunes, was carried out in this area. Comparing the current period to the 1990s, further dynamic growth of the development area can be observed, especially in the park's protective zone, with a simultaneous decrease in the forest area and agricultural land.

“…For China, given its large population and limited land resource per capita, arable land is a valuable resource [32][33][34][35][36][37]. However, in the last 30 years, this resource has been drastically reducing as a consequence of the rapid economic development [38][39][40][41][42]. According to statistical data, from 1987 to 2000, the area of arable land in China showed a net reduction of about 4.5 million hectares [43].…”

“…Clearly, this development represents a serious threat to regional food security and sustainable development. It has been reported that urban expansion usually leads to the loss of high-quality arable land because the distribution of urban areas and high-quality arable land usually shares similar land conditions such as the flat terrain and having resources close to the water [2,4,11,12,23,38,39,42,44,45]. However, whether rural settlement expansion prefers to consume high-quality arable land is still not clear now.…”

Settlement expansion caused by urbanization is an important factor leading to the loss of arable land across the world. Due to various factors in China, such as institutional problems, the total number of rural settlements is decreasing, while the total area continues to increase. Rural settlements expand mainly into arable land, resulting in a significant loss of high-quality farmland, thus threatening long-term food security. However, research on this subject is relatively scarce. In this study, using KeyHole and RESURS F1 satellite remote sensing images, we examined the spatial expansion of rural settlements in Tongzhou District, Beijing, in 1972 and 1991. Then, the consumption of high-quality arable land by rural settlements expansion was assessed. It was found that the overall accuracy of the produced maps for 1972 and 1991 were 93% and 90%, respectively. The accuracy of mapped changes from 1972 to 1991 was as high as 90%. From 1972 to 1991 and from 1991 to 2015, the rural settlements in Tongzhou District expanded by 51.54% and 79.91% respectively, with 53.72% and 60.64% of the expanded rural settlements being on arable land. Rural settlements expanded mainly into high-quality arable land at the beginning of the study period, whereas later on, medium- and low-quality farmland was also occupied, albeit to a lesser degree.
