“…In the case of BD, it was a negative correlation with total organic carbon (r = −0.81), TP, macroporosity (r = −0.71), and saturated hydraulic conductivity (r = −0.48) (Figure 4). These results are in agreement with previous studies in which a negative linear relationship was found between BD and macroporosity, and between BD and the saturated hydraulic conductivity (Baranian Kabir et al, 2020; Reichert, Suzuki, Reinert, Horn, & Håkansson, 2009). According to Chen, Huang, and Sun (2017), organic matter content has a dominant effect on soil BD and organic matter concentration is used to predict soil BD (Périé & Ouimet, 2008; Prévost, 2004).…”

“…BD is a structural index that is strongly related to TP, AP and consequently influences hydraulic properties and defines air: water relationships in the soil (Baranian Kabir et al, 2020; Blanco‐Canqui & Ruis, 2018; Pla, 2010; Reynolds, Drury, Tan, Fox, & Yang, 2009). The soil under the influence of decomposing wood differed significantly from the control sample in terms of capillary water capacity, which indicates a significant increase in the number of micropores capable of retaining water (Piaszczyk, Lasota, & Błońska, 2020).…”

“…Organic remains released from deadwood in the forest and LL in the agroecosystems is delivered to soil and determine soil structure and aggregation (Piaszczyk et al, 2020; Safaei et al, 2019). Understanding the effects of land‐use/cover change on the hydrological properties of soil is essential for sustainable land‐use/cover effective land management and soil quality improvement (Baranian Kabir et al, 2020). Therefore, SOC, AP, BD, and Ksat could play an important role for monitoring soil quality.…”

“…Numerous studies have shown that soil quality has suffered significant degradation worldwide as a result of anthropogenic disturbances due to land‐use change (Afanador‐Barajas et al, 2020; Andrews et al, 2003; Baranian Kabir, Bashari, Bassiri, & Mosaddeghi, 2020; de Lima, Hoogmoed, & Brussaard, 2008; Molaeinasab, Bashari, Tarkesh Esfahani, & Mosaddeghi, 2018; Safaei, Bashari, Mosaddeghi, & Jafari, 2019; Viana et al, 2014; Zhang et al, 2019) and natural processes (Peng et al, 2013; Pla, 2010; Zhang et al, 2019). However, under the conditions of the Ecuadorian Amazon, very few studies have been carried out to assess the impact of the change from forest to agricultural and livestock systems upon soil quality.…”

Few studies have comprehensively evaluated the effect of changing land use on the soil quality in the Ecuadorian Amazon region that is subject to continued deforestation processes. This study evaluated the influence of different types of land use on soil quality using an integrated soil quality index (SQI) with a minimum set of indicators, based on 140 soil samples from 7 land use types, in seven productive distinct landscapes in Pastaza Province, Ecuador. The land use type evaluated was Chakra_A, Chakra_B, Chakra_C, Cattle_A, Cattle_B, Cattle_C, and Forest. Land use type had significant effects on soil properties and thus on soil quality. SQI was developed by using, AP, Zn, TOC, BD, and LL; AP and Zn had highest weighting values (0.38), which indicated that these indicators contributed the most to final SQI. In general, the SQI varied significantly depending on the type of land use and two groups were established: the first categorized as of moderate quality with mean SQI values of 0.45, 0.44, and 0.41 for Chakra_A, Forest and Chakra_B, respectively; while the second group registered average SQI values of 0.33, 0.33, 0.32, and 0.30 for Chakra_C, Cattle_C, Cattle_A and Cattle_B, respectively, considered of low quality. The methods used are applicable to the study of changes in soil properties as functions of agroforestry systems, which are generated by changes in land use in similar landscape of the Ecuadorian Amazon.

“…These changes play important roles in shaping the landscape and altering land resources, sometimes with negative impacts 8 . Numerous scholars have concluded that unregulated land-use changes lead to environmental degradation that poses a major threat to the socioeconomic and ecological sustainability of soil as a vital resource 9 – 11 . Increasing pressure on land resources because of unsustainable cultivation, overgrazing, deforestation, climate change and drought, urbanization and poor land management practices are worsening land degradation on a global scale 12 – 15 .…”

Soil erosion (SE) and climate change are closely related to environmental challenges that influence human wellbeing. However, the potential impacts of both processes in semi-arid areas are difficult to be predicted because of atmospheric variations and non-sustainable land use management. Thus, models can be employed to estimate the potential effects of different climatic scenarios on environmental and human interactions. In this research, we present a novel study where changes in soil erosion by water in the central part of Iran under current and future climate scenarios are analyzed using the Climate Model Intercomparison Project-5 (CMIP5) under three Representative Concentration Pathway-RCP 2.6, 4.5 and 8.5 scenarios. Results showed that the estimated annual rate of SE in the study area in 2005, 2010, 2015 and 2019 averaged approximately 12.8 t ha−1 y−1. The rangeland areas registered the highest soil erosion values, especially in RCP2.6 and RCP8.5 for 2070 with overall values of 4.25 t ha−1 y−1 and 4.1 t ha−1 y−1, respectively. They were followed by agriculture fields with 1.31 t ha−1 y−1 and 1.33 t ha−1 y−1. The lowest results were located in the residential areas with 0.61 t ha−1 y−1 and 0.63 t ha−1 y−1 in RCP2.6 and RCP8.5 for 2070, respectively. In contrast, RCP4.5 showed that the total soil erosion could experience a decrease in rangelands by − 0.24 t ha−1 y−1 (2050), and − 0.18 t ha−1 y−1 (2070) or a slight increase in the other land uses. We conclude that this study provides new insights for policymakers and stakeholders to develop appropriate strategies to achieve sustainable land resources planning in semi-arid areas that could be affected by future and unforeseen climate change scenarios.

Surface soil hydraulic properties play critical roles in controlling water infiltration, evaporation, and soil water storage, in‐turn affecting the evolution of soil pore structure in cultivated desert soils of arid areas. The variability in soil pores and hydraulic properties caused by conversion of native semidesert soils to agroforestry use alters soil water storage and water budget in the desert–oasis ecotone. The objective of this study was to investigate that land use conversion alters surface soil hydraulic properties and enhances the contribution of soil macropores to water flow in the Linze desert–oasis ecoregion. Water infiltration and soil pores characteristics with nine replicates were measured using a disc tension infiltrometer across four habitat types (Haloxylon ammodendron shrublands, Populus gansuensis forests, Medicago sativa Linn grasslands, and Zea mays croplands) during the growing season. Soil properties and hydraulic conductivity characteristics clearly varied across the four habitat types. Saturated hydraulic conductivity was 0.177, 0.126, 0.118, and 0.031cm min−1 in the forest, grassland, shrubland, and cropland, respectively, with the corresponding average soil moisture being 7.6, 6.7, 0.9, and 19.2%. Clay content, bulk density, and initial soil moisture were the key soil physicochemical properties affecting saturated hydraulic conductivity (Ks). The macropores (> 0.5 mm in radius) accounted for 15–60% of total water flow, while 0.25–0.5 mm pores contributed to 12–24% across the four habitat types. The contribution of >0.5 mm pores to water flow in the forest was 3.3–4.0‐times greater than in shrubland and cropland, due to greater soil macroporosity (58 cm−3 cm3 ) and undisturbed soil pore structure. Land use conversion has a positive impact on soil properties, structure features, and soil hydraulic properties, and as a consequence, enhance the complexity of water exchange in the arid areas.
