“…At present, there are 32 national geoparks with karst landscapes as the main or auxiliary land type, accounting for 23.2% of the national geoparks. Among them, Shilin Karst in Yunnan, Libo Karst in Guizhou, Wulong Karst in Chongqing, Guilin Karst in Guangxi, Shibing Karst in Guizhou, Jinfoshan Karst in Chongqing, and Huanjiang Karst in Guangxi are nominated as World Natural Heritage Sites, highlighting the global value and importance of the karst landscape in Southwest China [19,20]. In general, China's KRDC measures have achieved remarkable progress, effectively supporting the sustainable development of Southwest China.…”

The ecological rehabilitation project has greatly curbed the serious problem of karst rocky desertification (KRD) in southern China and significantly changed the ecological environment and landscape pattern of the karst rocky desertification control areas (KRDCA). As one of the most important social–ecological fragile areas in the world, rural landscapes in KRDCA still show a strong sensitivity to disturbance. To reduce risks and improve the resilience of landscapes, this paper constructs a framework for assessing rural landscape resilience in KRDCA from the three dimensions of ecology, engineering, and social culture, based on the concept of resilience defined by the United Nations International Agency for Disaster Reduction. Considering the characteristics of rural landscapes in KRDCA, we select typical villages for empirical study. The results show the following: (1) The KRDCA is highly sensitive to natural disasters due to its special dual geomorphic structure characteristics. The disaster preparedness capacity of villages is the key factor determining the resilience of rural landscapes. The analysis of the disaster preparedness capacities of rural landscape structures with different vulnerability characteristics can be used as an effective means of evaluating the resilience level of rural landscapes in KRDCA. (2) Based on the empirical analysis of Fanhua village, which is a typical KRDCA in southern China, we found that the ecological system and engineering system of the village landscape have high resilience, while the resilience of the social and cultural systems are weak. This is due to the fact that the large number of rural population emigration in recent years has resulted in villages being at the key node of the reorganization of the social and cultural value system. The unstable sociocultural value system reduces the ability of rural landscapes to adapt to disturbance or environmental change. The study results could guide improvement strategies for subsequent landscape planning and inspire new ideas and methods for the implementation of rural revitalization strategies and the improvement of landscape resilience in KRDCA.

“…However, current disaster studies of karst mainly focus on single hazard aspects, such as the classification, formation, and evolution mechanisms of rocky desertification [27,28], drought-related soil and vegetation research [29,30], or the development of karst floods [31,32]. The phenomena of compound multiple disasters, e.g., drought and waterlogging (DW), and their temporal and spatial distribution has not been analyzed in-depth [33][34][35].…”

Under the synergetic effect of land use and climate change, natural disasters occur frequently in the karst region of southwest China. This study used the daily precipitation data from 33 meteorological stations across 61 years (1960–2020), utilized the MK test and the Z index to calculate the levels of drought and waterlogging (DW) at multiple times (month and year) and spatial (province, sub-divisions, station) scales, and investigated the spatiotemporal patterns and their associated factors in DW in the karst mountains of Guizhou, southwest China. The results showed that: (1) DW occurred frequently and increasingly during the study period in Guizhou, with seven mutations of annual DW. (2) There were more droughts (especially heavy droughts) based on annual data, but more waterlogging (especially heavy waterlogging) based on monthly data. Drought occurred most frequently in summer, while waterlogging was most frequent in spring, followed by winter. (3) The normalized difference drought and waterlogging index (NDDWI) was created in this study to exhibit combined DW phenomena, which could be improved in the future to better present the compound hazards. The spatiotemporal patterns of DW in Guizhou were complicated and associated with terrain, geology, climate change, vegetation, land use, etc.

“…Forest management can affect soil quality and the sustainability of the ecosystem [5]. The soil quality also reflects the interaction between the environment below ground and the vegetation above ground [6]. The Alas Bromo Forest has numerous land cover types, including pine, mahogany, pine-mahogany, a mixture of trees, open land, and seasonal plants [7].…”

Understanding the environmental services provided by healthy forest ecosystems needs accurate soil quality (SQ) assessments. Selecting appropriate SQ indicators is one of the keys to the effectiveness of SQ assessment. Earthworms have the potential to be bioindicators of soil quality because they are sensitive to environmental changes. This study aims to assess the soil quality level and evaluate the potential of earthworms as bioindicators in six land covers at the Alas Bromo Education Forest of Universitas Sebelas Maret, namely: pine, pine-mahogany, mahogany, mixed, annual crops, and pine replanting. SQ assessment is measured by calculating the Soil Quality Index (SQI) using Principal Component Analysis (PCA) with 10 Minimum Data Sets (MDS), namely: bulk density, earthworm abundance, C-organic, N-total, pH, porosity, exchangeable Al, cation exchange capacity (CEC), base saturation (BS), and available K. Statistical analysis using ANOVA, Duncan's Multiple Range Test, correlation, and regression. The results showed that land cover significantly (p-value < 0.01) affected SQI. The SQI for all land cover categories is poor, with the highest value on mixed land cover (0.36) and the lowest on pine-mahogany (0.31). The land cover also significantly (p-value < 0.01) affected earthworm abundance, with the highest on mixed land cover (365 individuals/m 2 ) and the lowest on pine replanting (25 individuals/m 2 ). Earthworm density as a determining indicator significantly correlated with SQI (r = 0.495) and contributed 24.5% to the SQI. Future research needs to test the effectiveness of earthworms as a bioindicator of soil quality in other land uses in different areas.
