“…Another study found that there were 16.9% and 5.4% increases in bare land and large-scale mechanized agriculture, respectively, as well as a 37% decrease in dense forest cover and a 20% increase in light forest cover in the Erawashda Forest in eastern Sudan. The expansion of mechanized agriculture, the cutting of trees, grazing and construction were the main factors contributing to forest degradation [27].…”

“…Sulieman and Elagib [26] compared the temperature, rainfall and aridity index with land cover change in the El-Gedaref region in east Sudan and found an increase in warming and arid areas. Another study determined the factors affecting land cover change in the Erawashda Forest between 1973 and 2015 [27]. However, besides Sulieman and Elagib [26], few studies have investigated the changes in vegetation coverage with meteorological parameters.…”

Arid regions worldwide, for example, Sudan, are affected by climate change and susceptible to environmental deterioration. In this study, temperature and rainfall data from 1985 to 2015 obtained from the Sudan Meteorological Authority were compared with satellite images of vegetation coverage in southern Port Sudan. The objective of this study was to determine the impact of climate change on the vegetation cover in this area. Results showed significant increases in the annual maximum, minimum and average temperatures with time, and precipitation showed a slight but not significant decrease from 1985 to 2015. The rates of increase for the annual maximum, minimum and average temperatures were 0.08 °C/year, 0.03 °C/year and 0.06 °C/year, respectively, and precipitation decreased at a rate of 0.12 mm/year. Higher shrub abundance and greater water area in 2013, 1995 and 1990 were probably due to high rainfall in the years preceding these years. Decreased shrub abundance in the year 2000 could be due to the significantly higher temperatures after 1998. There was no decreasing trend in shrub coverage from 1985 to 2015, but the overall increase in temperature and decrease in precipitation from 1985 to 2015 indicate a potential threat to vegetation in this area in the future.

“…Specific landscape metrics, such as largest patch index (LPI) and patch density (PD), have been considered robust for measuring fragmentation (Wang et al, 2014). Quantifying landscape structure with landscape metrics can be useful for acquiring spatially consistent findings, which provide biophysical processes driving landscape fragmentation (Sulieman, 2018). The use of simple metrics, instead of complex and usually correlated metrics is an unsettled issue of debate in landscape ecology studies (Bogaert et al, 2011).…”

Landscapes are composed of diverse units that associate with each other, and these units have different functions both in ecology and physiognomy. Thus, evaluating landscape character plays an important role for conserving biodiversity , as well as spatial planning and management of habitats and landscapes. Determining and analyzing environmental factors is an important part of assessing the conservation value of landscape types. For its ecological value, stone pine, botanical name Pinus pinea L. was chosen to be evaluated according to the environmental parameters in this research, because of its scattered distribution around the Mediterranean basin. Although P. pinea L. does not have a widespread distribution, it is naturally found in five regions of Turkey. This research was conducted in three provinces (Muğla, Denizli, and Aydın), located in western Anatolia. Maps representing different classes of soil, geology, aspect, and slope were overlaid in ArcMap 10.5, and characterized by Landscape Character Assessment (LCA). A total of 309 character types were determined, according to tree species composition, represented by 4 variants of the P. pinea L. community. To assess fragmentation among 34 different stands, landscape metrics were calculated using Fragstats v4.2 software. Potential range for regenerating stone pine stands was suggested in this paper, which can be considered as habitat corridors providing connectivity between mature stands. Spatial variation in bird species composition, reflecting wildlife richness, was evaluated as evidence for forest fragmentation.

“…Although the level of forest loss has lessened worldwide (FAO 2015), the issues of forest cover replacement still remains relevant at international meetings and conferences on global environment. Reliable and up-to-date information on the state of forest resources is necessary for land use planning and development (Sulieman 2018). A lot of researchers have emphasised the need for combining high resolution images, remote sensing data and aerial photography for understanding changes in land cover patterns (Brown et al 2000;Sader et al 2001;Sharma et al 2017;Sulieman 2018).…”

Background: Forest cover change continues to be one of the most important topics in global environment discussions and negotiations. In North Africa, there is a broad consensus on forest decline but available information on the extent and rate of degradation has been far lower than needed. The present study uses the example of the cork oak forest of Tlemcen (Hafir-Zariffet forest), North West Algeria, to provide spatially explicit and up-to-date information on forest cover changes. The goal was to fill a knowledge gap in a poorly studied area by determining the extent of changes in forest cover. Methods: Land use land cover maps of 1989, 1999, 2009 and 2019 were classified using Random Forest Algorithm in R software and change assessed via intensity analysis. Results: The results revealed that sparse vegetation was the dominant land cover at the end of the study period, although it decreased from 71.25% in 1989 to 65.24% in 2019. The lowest coverage was water body from 0.47% in 1989 to 0.18% in 2019. Sparse vegetation and dense forest experienced a major decline of 6.01% and 3.22% respectively. On the other hand, open forest (+6.96%), bare areas (+0.37%), settlements (+1.99%) and agricultural (+0.21%) increased. In the LULC transitions analysis, dense forest recorded loss for two consecutive periods (1989-1999 and 1999-2009). The path of conversion was mainly from dense forest to open forest, an evidence of anthropogenic activities. Conclusion: The findings show that the cork oak forest of Hafir-Zariffet suffered multiple pressures, which cause degradation of this natural heritage. These pressures continue to increase the fragility of forest ecosystem and can affect the rehabilitation or even its resilience. In order to conserve the dwindling cork oak forest, a sustainable and effective management which ensures ecological, economic and social balance should be adopted.
