“…Although based on these results, it can be concluded that both variables affect DSIA changes in western Iran, land surface fluctuations had a greater impact on the DSIA than the NDVIA variations. In agreement with the findings of this work, the inverse and linear relationship between the dust emissions and vegetation cover have also been reported in many previous studies (Azoogh and Jafari 2018;Kergoat et al 2017;Sofue et al 2018). In addition, a recent study concluded that LST is one of the main factors controlling dust events in many arid and semi-arid regions of Iran because it has shown a significant direct relationship with changes in DSI in these areas (Ebrahimi-Khusfi and Sardoo 2021), which also confirms the findings of the present study.…”

Sand-dust events (SDE) are an increasing concern in many arid and semi-arid regions of the world, which have severely damaged air quality and human health in recent years. This study was conducted to monitor the SDE in western Iran using the dust storm index anomaly (DSIA) during 2000-2018. The spatiot-emporal change detection and statistical analysis were used to understand the impacts of normalized difference vegetation cover anomaly (NDVIA) and land surface temperature anomaly (LSTA) on the SDE activities. The area has suffered from the highest dust pollution in 2004, 2009, and 2012 (DSIA>+40) while it experienced the lowest dust pollution in 2002 and 2017 (DSIA<-40).Approximately 48% of western Iran experienced decreasing changes and 52 % of the total area experienced increasing changes in dust pollution during 2010-2018 compared to the previous years. Incremental changes in NDVIA and LSTA were observed in 73.2% and 7.5% of the study area while their decreasing changes were observed in 26.8% and 92.5% of the total area, respectively. Spatially, regions affected by the increase in dust pollution are mainly distributed in the eastern and southern regions of the study area. Significant effects of changes in anomalies of both terrestrial parameters on DSIA were observed throughout the study period (R LSTA-DSIA= +0.52; R NDVIA-DSIA= -0.41); P<0.05). It was also found that spatial correlation between LSTA and DSIA as well as NDVIA and DSIA in many parts of the study area were significant at the 95% confidence level ( 45 . 0  R). These findings can be useful for decision-makers to assess the risks of dust pollution and reduce its negative consequences in western Iran.

“…In line with this result, Hashemimanesh and Matinfar (2012) reported that the petroleum mulch project in southwestern Iran decreased sand dune areas from 66.4% in 1991 to 56% in 2002. Similarly, Azoogh et al (2018) results indicated that petroleum mulching-biological fixation practices promoted the restoration of vegetation cover in the sand dunes. Therefore, this result is likely explained by the positive effects of oil-mulch treatment on vegetation cover and litter.…”

Wind erosion is one of the desertification results and is among the natural processes that mostly occur under dry conditions and high wind velocity. Using oil-mulches is one of the common methods to stabilize sand dunes. The current study aimed to investigate the short-term effects of oil-mulch on vegetation attributes (i.e., cover and diversity) and rangeland condition score (RCS) using integrated ecological and remote sensing-based approaches in arid regions of Southwestern Iran. A vegetation survey was carried out in 2019 in the oil-mulched and control area, and a remotely sensed vegetation index (MSAVI) was calculated for 2017 and 2019. The results indicate that one year after treatment, compared to the control area, vegetation cover (30 ± 17.11 vs. 17 ± 5.44 %) and litter (4.6 ± 2.18 vs. 0.94 ± 1.55 %) increased significantly in the oil-mulched area, while bare soil (65.20 ± 17.34 vs. 82.31 ± 5.84 %) decreased. Further, diversity indices (Species evenness, Shannon, and Simpson indices) declined by applying oil-mulch (88%, 63%, and 71%, respectively). The rangeland condition score was significantly higher in the oil-mulched area than in the control area (22 ± 1.86 vs. 12 ± 0.88; P < 0.001). Comparing MSAVI between 2017 and 2019 showed that vegetation cover increased 44.8%. Based on the results, it can be suggested that planting native palatable species in an oil-mulched area with the exclusion of livestock grazing is likely to increase the benefits of oil-mulch treatment and will lead to better rangeland condition score.

“…Land use change both enhances and weakens this increase. The growth of vegetation coverage decreases the power of wind and increases the function of sand fixation (Azoogh et al, 2018). Thus, sand fixation increased more in the northern CBYN owing to the growth of vegetation coverage, as demonstrated by NDVI.…”

Urbanization, an unavoidable global process, has driven land use change, impacted ecosystem services, and induced serious environmental problems. As a result, urban planning is a critical issue in sustainable development. In this study, we developed a framework to quantify how urbanization influences ecosystem services (ESs) in order to provide suggestions for urban planning during large scale urban agglomeration in northwestern China. We separated the region into three sub-regions (developed urban, developing urban, and rural areas), quantified five critical ESs (crop production, carbon storage, nutrient retention, sand fixation, and habitat quality), analyzed the relationships (trade-off, synergy, and bundle) among ES changes, and investigated the impacts of urbanization on these ESs. The results show that urbanization results in large scale reclamation and small scale deforestation in rural areas; it comprehensively results in an increase of four ESs (not habitat quality). Urban expansion mainly occurs in developing urban areas and causes a decrease in four ESs (not sand fixation). Based on temporal change in ESs, synergy relationships exist among them, except for between nutrient retention and crop production, which have an insignificant correlation. Urban expansion would strengthen the synergy relationships among regulating services, while green infrastructure in core urban areas would weaken these relationships. Based on the spatial distribution of ES change, two bundles were identified among the five ESs: 1) crop production, carbon storage, and nutrient retention; and 2) sand fixation and habitat quality. Based on these findings, several suggestions for urban expansion and land use planning are proposed to achieve an optimized balance between urbanization and ES protection. Investigating the impacts of rapid urbanization on ESs and their relationships could provide scientifically based suggestions for urban planning according to ES protection, sustainable urban development, and human well-being.
