Climate and land use change can influence susceptibility to erosion and consequently land degradation. The aim of this study was to investigate in the baseline and a future period, the land use and climate change effects on soil erosion at an important dam watershed occupying a strategic position on the narrow Strait of Hormuz. The future climate change at the study area was inferred using statistical downscaling and validated by the Canadian earth system model (CanESM2). The future land use change was also simulated using the Markov chain and artificial neural network, and the Revised Universal Soil Loss Equation was adopted to estimate soil loss under climate and land use change scenarios. Results show that rainfall erosivity (R factor) will increase under all Representative Concentration Pathway (RCP) scenarios. The highest amount of R was 40.6 MJ mm ha−1 h−1y−1 in 2030 under RPC 2.6. Future land use/land cover showed rangelands turning into agricultural lands, vegetation cover degradation and an increased soil cover among others. The change of C and R factors represented most of the increase of soil erosion and sediment production in the study area during the future period. The highest erosion during the future period was predicted to reach 14.5 t ha−1 y−1, which will generate 5.52 t ha−1 y−1 sediment. The difference between estimated and observed sediment was 1.42 t ha−1 year−1 at the baseline period. Among the soil erosion factors, soil cover (C factor) is the one that watershed managers could influence most in order to reduce soil loss and alleviate the negative effects of climate change.

“…However, some problems, such as ecological destruction, environmental degradation, and loss of biodiversity, have followed, posing a serious threat to the sustainable development of society (Barbier et al 1996; Baranova et al 2016). Arid areas, where water resources are limited, vegetation is sparse, and the environment is harsh, have become an area where a poor quality of life remains (Irajpoor and Latif. 2011).…”

Background: The lower reaches of the Tarim River is an arid region of inland China. In this area, vegetation is sparse and the environment is fragile. Therefore, it is of great significance to study the structure and stability of the plant community and ecosystem in the lower reaches of the Tarim River. It is valuable to increase the understanding of ecological protection and restoration in arid areas. Methods: In this study, four sections, Yingsu, Karday, Alakan, and Yiganbjm, were selected as research sites, and 96 arbor and shrub quadrats and 288 herb quadrats were delimited in these sites. The ecological characteristics of all species in the quadrats were investigated. We selected the surveyed data from 2000, 2004, 2008, 2012, 2016, and 2019. Based on the data, we analyzed the variations in species composition. We also determined Shannon-Wiener indexes, Alatalo indexes, and ecological dominance to discuss the species diversity and uniformity of plant community. Plant community stability were also evaluated. Results: There were 17 species in 2000 and 31 species in 2019. The proportion of arbor and shrub species decreased, while the understory herbaceous species gradually increased; all of the species become balanced. The stability of the plant community gradually increased; however, it remained unstable. Conclusions: In general, water conveyance in an ecosystem plays a positive role in promoting the restoration of vegetation and ecological stability. This study provides a new method for the evaluation of ecological protection and restoration benefits in arid areas. Our findings can be a good reference for similar studies.
