Using the PLUS model, it simulates land use changes in the Panxi Dry Valley by 2035 and incorporates convex hull model validation to construct a multi-tiered urban development boundary system—comprising baseline, elastic, and priority boundaries. The results indicate that: (1) the western subregion emphasizes ecological protection, whereas the central subregion prioritizes both agricultural production and urban development; (2) under the Natural Development Scenario, construction land expands substantially by 2035, while the Policy-Driven Scenario effectively limits expansion, highlighting the regulatory role of policy constraints; and (3) the areas delineated for the baseline, elastic, and priority boundaries are 313.37 km², 5882.12 km², and 25,023.94 km², respectively. This approach integrates spatial planning with policy-oriented constraints, providing a systematic framework for hierarchical boundary delineation.

Utilizing data from 398 respondents collected over nine months, the research identifies drought as a significant agricultural threat, with farmers reporting increased frequency and intensity. To enhance resilience, farmers employ six primary strategies: cultivating drought-resistant crop varieties, diversifying crops, adjusting cropping calendars, improving irrigation systems, practicing intercropping, and conserving soil moisture. The study reveals that socio-demographic factors and land tenure security significantly shape these adaptation decisions. Secure land tenure facilitates investment in sustainable practices, thereby positively influencing food security and poverty alleviation. Conversely, land-use conflicts create legal uncertainties that hinder long-term resilience. These findings underscore the necessity for targeted policies that resolve land disputes and secure tenure, enabling a transition from short-term coping mechanisms to sustainable adaptation strategies.

Although measuring sustainability poses challenges, it remains crucial for developing specific management strategies designed for a given geographic area. This study introduces the Management Impact on Soil Quality (MISQ), an integrated indicator designed to assess how common management practices influence the attributes of soil health in organic vineyards. The MISQ evaluates five key management components: soil disturbance, regeneration of soil organic matter, terrestrial eco-toxicity impact of copper, efficiency of nutrient (NPK) use, and biodiversity. This indicator was applied using data collected from an organically-managed vineyard in Franciacorta, a grape-producing area in Northern Italy over the years 2014, 2015, 2019 and 2021. The results indicate how enhanced soil function depends on increased supply of organic matter and diversified cover cropping with legumes, thereby improving soil biodiversity. However, managing potential nutrient surplus and recognizing the risks associated with tillage for row spacing management are also crucial factors. These results provide viticulturists with a valuable tool for assessing the effects of agronomic techniques on soil quality, thereby facilitating sustainable management practices. This study highlights the need to preserve the soil multifunctionality, which is critical for nutrient cycling, soil structural stability and biological population control. The straightforward approach of the MISQ makes it suitable for use in different environments, thereby promoting effective management strategies that mitigate a negative impact on soil functionality.</div></div>","PeriodicalId":36171,"journal":{"name":"Environmental and Sustainability Indicators","volume":"27 ","pages":"Article 100732"},"PeriodicalIF":5.4,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144166489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our findings uncover profound implications of the national park pilot scheme on ESV in giant panda habitats: a remarkable increase in ecological land, reaching 1430 square kilometers, with non-ecological land primarily converted into ecological space through reforestation and afforestation initiatives. The ESV within GPNP displayed a distinctive trajectory, initially declining then rebounding, predominantly driven by forest land and water. In GPNP, natural factors predominate as chief ESV contributors. Contrarily, the surroundings experienced varying influences from both natural and human activities until 2015, followed by a distinct shift in ESV regulation under the GPNP's establishment, suggesting a dominance of natural factors afterward. This research highlights the positive impact of establishing a national park, not only enhancing ESV within its boundaries but also spillover effects on adjacent habitats, culminating in a consistent ESV uplift across the study area.

Monitoring microplastics presence in different environments is crucial, and employing simple, cost-effective methods, such as using insects as bioindicators, can be highly effective. In this pilot study, Carabid beetles (Coleoptera: Carabidae), a terrestrial insect group, were used, for the first time, to investigate their potential as bioindicators for microplastics in soils. Their biological and morphological characteristics, along with their broad distribution, make them ideal candidates for assessing the presence of microplastics in terrestrial environments. Monthly sampling was conducted from July to October 2022 using pitfall traps at three sites along the Conero coast (Italy), differing in the degree of human influence. Microplastics were extracted from organisms' guts using oxidative digestion and vacuum filtration and then characterized through optical microscopy and μFT-IR spectroscopy. Findings revealed that 32 % of Carabid beetles ingested microplastics. While no consistent spatial or temporal patterns were observed in the number of particles found per individual, ingestion frequency varied significantly among sites (Pearson's chi-squared test, p = 0.028). Site C, a stony beach subject to intense summer tourism, exhibited the highest ingestion rates (75 % in July, 87.5 % in August). Most microplastics were primarily fragments of 0.1–1 mm in size, with polyester and silicone being the most prevalent polymers. Given limited information available on microplastics contamination in soils, this pilot study confirms that Carabids are effective bioindicators of the presence of soil microplastics, and demonstrated a link between microplastics pollution and anthropogenic presence.</div></div>","PeriodicalId":36171,"journal":{"name":"Environmental and Sustainability Indicators","volume":"27 ","pages":"Article 100729"},"PeriodicalIF":5.4,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144117044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite its importance, existing assessment frameworks often lack spatial adaptability and fail to account for local hydrogeologic complexity, data limitations, and implementation constraints. This study introduces the Iranian Groundwater–Surface Water Interaction Method Selection Decision Tool (IR-GWSW-IA-MSDT), a modular, semi-quantitative framework designed to facilitate scientifically robust and context-sensitive selection of GW/SW assessment methods. The tool synthesizes hydrogeological and socioeconomic indicators, spatially calibrated across 609 officially delineated study areas in Iran, to quantify the relative importance of GW/SW interactions. It employs a dual-pathway decision structure: the first ranks candidate methods based on their alignment with interaction importance scores and expert-assessed accuracy; the second filters methods according to user-defined objectives, data availability, technical feasibility, and site constraints. Evaluations incorporate both compatibility and functional adequacy across interaction types, including river–aquifer interaction, return flow, and precipitation-driven recharge. Application to three representative basins—Dezful-Andimeshk, Tehran-Karaj, and Urmia—demonstrates the tool's capacity to recommend hydrologically appropriate and operationally feasible methods across diverse GW/SW regimes. Unlike conventional frameworks, IR-GWSW-IA-MSDT explicitly integrates unsaturated zone dynamics and enables flexible reconfiguration for regional or international contexts. By aligning method selection with both environmental relevance and institutional capacity, the tool supports improved groundwater–surface water governance and contributes to sustainable development goals (SDGs), particularly SDG 6 (Clean Water and Sanitation) and SDG 13 (Climate Action).</div></div>","PeriodicalId":36171,"journal":{"name":"Environmental and Sustainability Indicators","volume":"27 ","pages":"Article 100726"},"PeriodicalIF":5.4,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144125164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
