Fragmentation and Isolation
Published in Yeqiao Wang, Landscape and Land Capacity, 2020
The importance of scale is widely recognized and considered throughout the broad field of ecology and is of specific relevance to the field of Landscape Ecology. Landscape Ecology specifically addresses broad and fine-scale spatial patterns and ecological processes and the hierarchical nature of these ecological processes.[25–28] Fragmentation and the isolation of remnant habitat can occur on different spatial scales and the effects may occur at different temporal scales (i.e., time lags between fragmentation and effect). The choice of scale assessment can affect the analysis of fragmentation and there is no single correct scale for analysis; the relevant scale being different for each species. Many forest fragmentation studies have been conducted to specifically investigate the effect of scale on the analysis of fragmentation.[29–33] It is widely accepted that any analysis of fragmentation and isolation should occur at multiple scales so the effect of scale on the response (e.g., species abundance, biodiversity, community indices) can be assessed at scales ranging from small (fine grain resolution) to large (landscape level extents). The temporal scale should also be considered by using long-term studies or meta-analyses that incorporate population-level responses over time to account for time lags between the fragmentation of habitat and the manifestation of species responses.

At the landscape level, the movement of organisms and substances between habitat patches becomes a critical factor in the maintenance of overall ecological processes. Also important is the interaction of organisms and physical processes located in different habitat patches. What happens in one area of the landscape can have an impact on other areas. The study of these factors, and how they are shaped by the spatial patterning of the landscape, is known as landscape ecology. Because it helps us understand how the different parts of the landscape mosaic are formed and how they interact, landscape ecology provides a good basis for management of the agricultural landscape (Turner et al. 2001; Burel et al. 2013; Landis 2017).
The role of landscape metrics In environmental planning and management of mining activities
Published in Heping Xie, Yuehan Wang, Yaodong Jiang, Computer Applications in the Mineral Industries, 2020
Landscape ecology relies in three main characteristics: landscape structure (or pattern), landscape functions (or ecological processes), and the continuous change of these two characteristics across time. Spatial structure influences many ecological processes, and landscape planning and management, in turn, influence landscape structure. Identifying the main landscape structural elements and functions is crucial to understand how landscapes work. The establishment of relationships between the two components allows predicting which will be the ecological consequences of the proposed spatial solution(s).

As an important part of ecological risk assessment, landscape ecological risk (LER) assessment has enriched and expanded ecological risk research and has played an important role in ecological assessment and environmental management (Peng et al. 2015; Tian et al. 2019). Specifically, LER assessment refers to the analysis of the response of landscape element mosaics, landscape pattern evolution and landscape ecological processes to internal risk sources and external disturbances (Peng et al. 2015). LER assessment is different from traditional ecological risk assessment methods. It relies on the perspective of coupling between ecological processes and spatial patterns in landscape ecology and particularly emphasizes the spatiotemporal heterogeneity and scale effects of ecological risks (Qiao et al. 2021; Han et al. 2022). Several geospatial techniques have been extensively used in the LER research (Li et al. 2018; Xie et al. 2021). Therefore, many scholars have conducted LER assessments based on landscape patterns to explore the spatiotemporal heterogeneity of ecological risk (Liu et al. 2018; Xie et al. 2021; Ran et al. 2022). Based on the theory of landscape pattern-process association, the LER assessment can directly reflect the ecological risks in the structure and composition of landscape patterns (Fu 2014; Zhang et al. 2020).

Human activities have played a significant role in the emergence of environmental and ecological deterioration in Nigeria (Tyokumbur, 2014). Traditional bush burning and open animal grazing have both played a part in Nigeria’s deforestation and desertification problems (Geist & Lambin, 2002). Both have the resultant effect of continuing to degrade the soil and biodiversity of the impacted regions and increase financial losses in the agriculture sector (Leke and Leke 2019). The social-economic development consequences of such high levels of pollution include a loss of biodiversity in the natural environment and a threat to food security consequent upon the outcome of soil contamination (Leke and Leke 2019). The erratic nature of public power has been a cog in the wheel of promoting environmental sustainability, and reliance on fossil fuel-powered power producers contributes to noise and air pollution (Mauree et al., 2019). As a result, the built environment plays a critical role in ameliorating the impacts of the climate change and obtained sustainable energy economy (Agboola 2011a; House of Lords 2016). Landscape ecology, which supports the significance of local variations and interactions between sections of an ecological system, has had a big influence on environmental sustainability notions (Msumba, 2006; Mickaityte et al., 2008; Shittu 2020). These ideas have since been expanded to include resilience in the context of human – environmental relationships as well as the importance of cultural capital in achieving regional sustainability (Warner, 2011; Silva et al., 2020; Van der Waal and Thijssens 2020).
An interactive platform for the analysis of landscape patterns: a cloud-based parallel approach

The ecological impacts of land use and land cover change are profound, and numerous examples in the literature have highlighted environmental impacts of future urban development (Gustafson 1998; Nagendra, Munroe, and Southworth 2004). To better understand human interactions with natural systems, landscape ecology plays an important role to analyse land use change pattern and spatial fragmentation (Turner and Lynn Ruscher 1988; Turner 1989, 1990). The results of such analyses can further guide decision-making in urban planning and natural ecological studies.
