“…Landscape metrics are widely used in studies on landscape variability over the years [19,23,[25][26][27], both in terms of ecological and visual values [28]. The metrics are used to analyze the state, the characteristics of the spatial structure, and the functioning of various types of landscapes, including urban [23,26,29], rural [30][31][32], forest [19], and degraded landscapes (e.g., by extractive industries and intensive agriculture [33]). As emphasized by Roo-Zieli ńska et al [20], landscape metrics, apart from their use in indication, also have a wider meaning.…”

Landscape metrics have been used for years in research on the evolution of landscapes. They are also important in the process of monitoring changes taking place in the functional and spatial structure of rural areas. The main aim of this article is to assess the transformation of the rural landscape of the Puchaczów commune, which is based on a comparative analysis of selected landscape metrics. In the Puchaczów commune, due to the availability of raw materials, a mining industry has developed, which has a decisive influence on the development of the region. The study included schemes of the commune’s land cover from four periods: the pre-war period, the 1960s and the 1970s (i.e., shortly before the construction of the hard coal mine), 1990–2000, and 2020. Then, for the given time frames, with the help of the FRAGSTATS version 4.2 program, the following landscape indicators were calculated: the percentage of the landscape coverage by particular land cover units, the number of patches, the mean class area, the Shannon diversity index, and the Simpson diversity index. A comparative analysis of landscape metrics showed that the landscape of the Puchaczów commune was constantly transformed in the years 1937–2020. Despite the decrease in the area of agricultural land, agricultural production remains the dominant function of the commune. The percentage of industrial areas is the smallest, but the metric values do not reflect the enormous environmental impact of the mine. A broader description of the changes taking place in the landscape of the Puchaczów commune can therefore be obtained only by combining research with the use of landscape metrics and analyses of the impact of land cover units on the environment.

“…The significance of this period is that it marks the beginning of democracy in South Africa and, subsequently, a move towards more inclusive policy. Within the landuse and transport context, landscape metrics have been applied to understand rural planning (Wu, Kuo, & Zhang, 2016), urban planning and development (Botequilha Leitão, & Ahern, 2002), urban sprawl, land-use transition and urban growth (Herold et al, 2003;Herold, Scepan, & Clarke, 2002;Ji, 2008;Nkeki, 2016;Weng, 2007) and transportation planning (van der Ree, Jaeger, van der Grift, & Clevenger, 2011), among others.…”

Abstract:The marginalization of low-income earners, in regard to access to economic activities, is a topical issue in South Africa. The location of residential areas relative to locations of employment plays a large role in determining how accessible employment opportunities are to individuals. This has led to several studies that look at the polarization of growth in places of economic activities in more affluent suburbs within the discourse of social exclusion and transformation. Since South African independence, several policies were drafted to address issues of segregation and social exclusion, among other issues. However, the question remains whether there has been progress in addressing these issues. This research applies landscape metrics to understand the growth trends in the spatial location of residential areas, relative to centers of economic activities, from 1995 (start of democracy) to 2013. The analyses reveal that high-and middle-income residential areas are typically located near commercial land uses. This explains the mixed land-use patterns that are found in middle-income residential areas. On the other hand, low-income residential areas were observed to be, dominantly, in large homogeneous and continuous patches.

Forest fragmentation in China and its effect on biodiversity

et al. 2019

Land‐use change is fragmenting natural ecosystems, with major consequences for biodiversity. This paper reviews fragmentation trends – historical and current – in China, the fourth largest country on Earth, and explores its consequences. Remote sensing makes it possible to track land‐use change at a global scale and monitor fragmentation of dwindling natural landscapes. Yet few studies have linked fragmentation mapped remotely with impacts on biodiversity within human‐modified landscapes. Recent reforestation programs have caused substantial increases in forest cover but have not stopped fragmentation, because the new forests are mostly monocultures that further fragment China's remnant old‐growth lowland forests that harbour the highest levels of biodiversity. Fragmentation – and associated biodiversity declines – is unevenly distributed in China's forests, being most problematic where agricultural expansion is occurring in the southwest and northeast, serious in the densely populated eastern regions where urbanisation and transport infrastructure are modifying landscapes, but less of a problem in other regions. Analyses of temporal trends show that the drivers of forest fragmentation are shifting from mainly agricultural expansion to urbanisation and infrastructure development. Most of China's old‐growth forests persist in small, isolated fragments from which many native species have disappeared, on land unsuitable for human utilisation. Fragmentation throughout China is likely to have major consequences on biodiversity conservation, but few studies have considered these large‐scale processes at the national level. Our review fills this research gap and puts forward a systematic perspective relevant to China and beyond.
