“…In this study, we used InVEST as a spatially explicit integrated modelling tool and a set of Geographical Information Systems models to quantify and assess spatial-temporal changes in soil erosion potential (Sharp, 2014). Various tools from this package have been used frequently in different case studies to quantify ESs (Asadolahi et al, 2017;Zarandian et al, 2017).…”

“…The potential of each watershed for soil retention was assessed through a combination of different data sets of LULC, precipitation, soil properties, and topographic conditions (Sharp, 2014;Asadolahi et al, 2017;Zhu et al, 2019). In this module of InVEST, the universal soil loss 2equation (USLE) (Wischmeier & Smith, 1978) was used, measuring the erosion rate and then calculating the SR rate (Borselli et al, 2008).…”

“…The soil erodibility factor is the rate of soil erosion per unit of rainfall erosivity index (Wang, Zheng, Römkens, & Science, 2013). This factor depends on different drivers such as soil texture, soil structure, organic matter, and soil permeability characteristics (Asadolahi et al, 2017). The soil erosion factor is estimated based on tons per hectare per hour per hectare mega Joule/ mm (t. ha.h/ha.MJ.mm).…”

“…InVEST is a geospatial tool for evaluating the impact of LULC change on various ESs (Sharp et al, 2016). In terms of SRS estimation, Asadolahi et al (2017) used InVEST tool to generate an SRS map in the Hyrcanian forest, Iran. In another study, Arunyawat and Shresth (2016) imported the LULC dataset, rainfall, soil characteristics, and topography into the InVEST to extract the SRS in Thailand (Arunyawat & Shrestha, 2016).…”

Globally, urbanization changes land use/land cover (LULC) and alters ecosystem functions and services. Soil retention (SR) is a critical ecological service that is strongly related to LULC change. The topic of this study is assessment of LULC change on soil retention service (SRS) in a fragile seminatural-urbanized landscape of the Jajrood basin in Northern Tehran, Iran, from 2000 to 2020. To achieve the goal, the LULC maps and the other relevant datasets were imported into the Integrated Valuation of Ecosystem Services and Trade-offs tool (InVEST) using the Universal Soil Loss Equation (USLE). Calibration and validation were performed using Goodness-of-fit test for observational and modeled data. The results revealed that LULC change had both negative and positive effects on SR. The built-up area increased dramatically by about 133 percent, while the rangeland shrunk by approximately 5 % during the twenty-year, leading to an increase in soil erosion and reducing SR. On the other hand, the agricultural and gardening activities expanded by 41 %, which caused an increment in SR. Due to the outgrowth of man-made areas compared to the other land uses, the overall SR decreased by about 17,000 tons. Moreover, the result indicated that slope, elevation, and land management factors, respectively, had the highest correlation with SRS. The finding of this research can provide insight to land use planners to protect the areas with high soil erosion.

This study was carried out according to the following objectives in the Shoor River Basin in southwestern Iran: (i) Evaluation of ecosystem services (ES) including habitat quality (HQ), carbon storage (CS), nutrient export (NE), and soil export (SE) using the InVEST approach as well as soil quality (SQ) using an integrated quality index; (ii) Assessment of the relationship between ES and SQ with landscape metrics using Pearson correlation test; and (iii) Investigation of the interaction between ES efficiency, SQ and landscape fragmentation using a ternary plot. The results showed that the northern and eastern parts of the region are prioritized for HQ, CS, and SQ but the southern and western parts for NE and SE. The highest ES efficiency and SQ were found for the forests as well as for the ridge/tops landforms. Statistical analysis clarified that there was a positive and significant relationship between HQ and CS (R>0.8) while the relationship of the two with NE was inverse and significant (-0.55<R<-0.50). The correlation between SE and NE was also positive and significant (R>0.50). SQ was also correlated positively and significantly with HQ and CS (0.43<R<0.5) while no relation with NE and SE was found. It was also perceived that increasing the landscape fragmentation decreases HQ, CS, and SQ but increases NE and SE. Besides, the interaction between ES, SQ, and landscape fragmentation across the sub-basins of the study area can change under the influence of the dominant land use and landform types.

The current era has been termed the “Anthropocene,” because of the irreversible impact of human activities. Land use change and urban growth are examples of these disturbances leading to the reduction in many ecosystem services (ESs). The subject of this study, Gorgan, has undergone significant changes that significantly affected the area. Studying these changes and understanding their effects on the ecosystem is essential. An integrated method was used to investigate the process of changing the urban ESs over 35 years, considering the physical and ecological characteristics of the area. This marks the first time such a study has been conducted using the hexagonal unit. Then, the composite total ecosystem services (TESs) index was calculated from the modeled and quantified combination of six ESs, including water yield, flood volume, net primary production, soil retention, carbon sequestration, and air pollution removal. Thereafter, the ESs were mapped and evaluated across time and space. The TES is proposed as an appropriate measure for quantifying ES supply and can indicate the overall function of ESs. According to the findings, the TES value declined from 0.427 in 1985 to 0.247 in 2005 and declined to 0.192 in 2020. Moreover, the Hyrcanian forests were the main source of the highest TES in Gorgan city, whereas urban areas had the lowest levels. The shortage of ESs in the study area has resulted in various crises. These include reduced air quality, heightened flood risk, soil erosion, and ecological imbalances in urban regions.
