To understand the impact of soil properties and land use systems on earthworm diversity in the biodiversity-rich Eastern Ghats Highlands of India, the present study was carried out in six land use systems i.e., moist deciduous forest, dry deciduous forest, fallow land, cropland, compost pit, and, sewage soil. The study area has been divided into 10 × 10 km2 grids and 25% grids were randomly selected for sampling from May to December 2022. A total of 16 species of earthworms under 14 genera and 8 families were recorded in this study, out of which 15 species are new records for the region. The most taxonomically rich family was the Megascolecidae. The most abundant species are endogeic followed by epigeic and anecic. Based on Hill numbers, the highest values of Shannon index (1D= 9.89) and Simpson diversity (2D= 9.14) were found for the fallow land. Earthworm abundance showed a significant difference among six land use systems [F (5,84) = 3.25, p = 0.01]. Furthermore, earthworms showed a significant positive relationship with moisture (r = 0.22, p < 0.05), organic Carbon (r = 0.25, p < 0.05), available Nitrogen (r = 0.22, p < 0.05), and clay content (r = 0.43, p < 0.01), whereas negatively correlate with sand content (r = 0.32, p < 0.01) of soil. High species richness was observed in cropland due to the high moisture, pH, organic Carbon, Potassium, and, Phosphorus content of the soil. The presence of a high number of native species urges their conservation in this region through land management.

“…Forests, mainly Tropical Moist Deciduous Forests and Tropical Dry Deciduous Forests cover 24.51% of the total study area (FSI 2021). Cropland is the major land cover in the study area (34.2%) based on a rainfed cropping system (Adhikary et al 2019). The majority of the region's agriculture is rain-fed and mono cropped.…”

“…In the third sub-stage, an error matrix was proposed to assess the accuracy. The confusion matrix had several statistics and thus could assess the accuracy in relation to several aspects [56]. In general, by using the error matrix, we could calculate the overall accuracy, Kappa coefficient, producer accuracy, and user accuracy.…”

Settlement expansion caused by urbanization is an important factor leading to the loss of arable land across the world. Due to various factors in China, such as institutional problems, the total number of rural settlements is decreasing, while the total area continues to increase. Rural settlements expand mainly into arable land, resulting in a significant loss of high-quality farmland, thus threatening long-term food security. However, research on this subject is relatively scarce. In this study, using KeyHole and RESURS F1 satellite remote sensing images, we examined the spatial expansion of rural settlements in Tongzhou District, Beijing, in 1972 and 1991. Then, the consumption of high-quality arable land by rural settlements expansion was assessed. It was found that the overall accuracy of the produced maps for 1972 and 1991 were 93% and 90%, respectively. The accuracy of mapped changes from 1972 to 1991 was as high as 90%. From 1972 to 1991 and from 1991 to 2015, the rural settlements in Tongzhou District expanded by 51.54% and 79.91% respectively, with 53.72% and 60.64% of the expanded rural settlements being on arable land. Rural settlements expanded mainly into high-quality arable land at the beginning of the study period, whereas later on, medium- and low-quality farmland was also occupied, albeit to a lesser degree.

“…Population growth and political agendas aiming for agricultural intensification through the propagation of settled agriculture have recently increased the pressure on productive land in South and Southeast Asia (Bose, 2019; Bruun et al, 2017; Castella et al, 2013; Fox et al, 2014; Rasul & Thapa, 2003; Ziegler et al, 2012). As a consequence of increasing land competition, shifting cultivation has migrated toward higher altitudes (Adhikary et al, 2019; Feng et al, 2021; Nongkynrih et al, 2018) and fallow cycles have been reduced (Choudhury & Sundriyal, 2003; Lestrelin et al, 2012; Prokop & Poreba, 2012; van Vliet et al, 2012), thus increasing the risk for soil erosion and challenging the sustainability of shifting cultivation systems.…”

Shifting cultivation will face increasing pressure from erosion‐related land degradation caused by rising cultivation intensities and climate change. However, empirical knowledge about future trends of soil erosion and thus land degradation in shifting cultivation systems is limited. We use the Environmental Policy Integrated Climate (EPIC) model to first explore the combined effects of climate change and agricultural intensification on soil erosion of uphill shifting cultivation systems, using six surveyed soil profiles. We assess interactions between climate change, the length of the fallow period, and slope inclinations for a near (2021–2050) and far (2071–2100) future period, considering three climate scenarios, five climate models, fallow periods between one and 20 years, and slopes between five and 70% steepness. Our results show a significant nonlinear relationship between global warming and erosion. Until the end of the century, erosion is estimated to increase by a factor of 1.2, 2.2, and 3.1 under the SSP126, SSP370, and SSP585 scenarios, respectively, compared with the historical baseline (1985–2014). Combined effects from climate change, fallow length, and slope inclination indicate that steep slopes require longer fallow periods, with an increase of slope from 5% to 10% multiplying the required fallow length by a mean factor of 2.5, and that fallow periods will need to be extended under higher global warming if erosion rates are to remain at current levels. These findings are novel as they link climate change effects on shifting cultivation systems to different slopes and fallow regimes, making an important contribution to understanding future erosion dynamics of traditional smallholder production systems in mountainous terrain, with relevant implications for policies on agricultural intensification.
