This study introduces a novel spatially explicit modeling framework developed to quantify the secondary environmental benefits of groundwater protection strategies in karst landscapes, with specific application Hranice Abyss region. The model employs multi-criteria decision analysis, integrated hydrological and high-resolution random forest-based prediction algorithm, downscale land surface temperature (LST) order obtain 1 × m spatial results. primary contribution this research lies its capacity assess not only core objectives but also wider impacts, including enhanced stormwater retention mitigation increases. Key predictors include use cover data, is adaptable across diverse landscape types. In case area, water demonstrated an increase up 30%, average rise precipitation 18.2 mm per microbasin. However, reductions were more modest, maximum decrease 7.3%, corresponding drop 1.5 °C. further identified pronounced seasonal land-use-specific variations temperature, particularly on agricultural land, where fluctuations reached 2.6 °C between pre- post-harvest periods. findings offer critical insights into how targeted land-use interventions can safeguard resources enhance resilience climate change. As such, approach provides essential tool for advancement sustainable resource management climate-adaptive planning.

ABSTRACT Carbon stock is a key element of land‐based ecosystems and serves as one the indicators for assessing SDG 15.3, which undergoes direct or indirect effects due to changes in land use. Utilizing central Yunnan urban agglomeration (CYUA) study region, we constructed Markov‐Multi‐Objective‐patch‐generating use simulation (Markov‐MOP‐PLUS) coupled model across four distinct scenarios: sustainable development scenario (SDS), economic (EDS), ecological protection (EPS), natural (NDS) year 2030. The Integrated Valuation Ecosystem Services Trade‐offs (InVEST) was employed carbon spatially identifying comparatively analyzing over time different areas reserves region between 2000 We used optimal parameter geographic detector (OPGD) exploring driving factors spatial differentiation stocks quantitatively 15.3. revealed that according scenarios modeled, region's future expected show expanded watershed construction zones.

Global challenges such as climate change, ecological imbalance, and resource scarcity are closely related with land-use change. Arid land, which is 41% of the global land area, has fragile ecology limited water resources. To ensure food security, resilience, sustainable use resources, there a need for multi-scenario analysis change in arid regions. carry this out, multiple spatial techniques indicators were used to analyze typical inland river basin Northwest China—the Tailan River Basin (TRB). Then, PLUS model was analyze, certain time period (1980–2060), same basin. The scenarios included Natural Increase Scenario (NIS), Food Security (FSS), Economic Development (EDS), Water Protection (WPS), Ecological (EPS), Balanced Eco-economy (BES). results show that 1980–2020, TRB mainly driven by changes cultivated grassland, forest built-up land.

Climate change is a major challenge impacting food security globally. Sub-Saharan African (SSA) countries including Nigeria has experienced the negative effect of climate vagaries most especially on agricultural production, thus, leading to insecurity. However, sustainable land management (SLM) practices have huge potential minimize impacts in rapidly changing climate. This study estimates determinants adoption SLM and impact household among smallholder rice farmers Ogun State, Nigeria. A multistage sampling procedure was used select 120 respondents. Poisson endogenous treatment (PET) model employed analyse level area. To account for counterfactuals, doubly-robust augmented-probability-weighted regression adjustment (APWRA) also used. In same vein, marginal effects (MTE) approach estimate heterogeneity. The results showed that socio-economic factors greatly influenced practices, such as age educational farmers. found be improved when they package consisting variety hence, alleviate insecurity if well combined large extent. concluded knowledge form formal education, some vocational training, trainings access weather information were key influencing untreated (ATU) are lower than ATE ATT, confirming positive selection unobserved gains. particular, ATU show an average non-adopting household, would significantly improve dietary diversity by about 27%.

The biodiversity–ecosystem function (BEF) relationship is the basis for studying restoration of degraded ecosystems, and simultaneous assessment multi-trophic-level biodiversity ecosystem multifunctionality more conducive to unravelling mechanism especially forest ecosystems with harsh habitats infertile soils such as karst. In this study, we evaluated soil (SMF) karst forests (scrub, SB; secondary growth forests, SG; old-growth OG) in Maolan National Nature Reserve, China, using 30 sample plots. Biodiversity at three trophic levels (plant–soil fauna–soil microorganisms), were assessed through vegetation surveys sampling. One-way ANOVA showed that SMF increased natural restoration, but multi-trophic level different trends. Pearson’s correlation analysis a positive between plant species diversity (p < 0.001), whereas fauna microorganisms negatively correlated SMF. Structural equation modeling revealed cascading effect on stimulation during restoration. Only exhibited direct driving plants indirectly influenced fauna, which subsequently affected Although observed negative effects microbial terms quantitative relationships, increase evenness still contributed This study promoting emphasized microbes are key unraveling mechanisms processes, an important intermediate link.

Mapping cultural ecosystem services (CES) in river basins is crucial for spatially identifying areas that merit conservation due to their significant CES contributions. However, precise quantification of the appropriate area mapping units, which basis assessment, rare existing studies. In this study, optimal threshold units (OATMU) identification, consisting a multi-dimensional indicator framework and methodology validation, was established clarify boundary CES. The included geo-hydrological (GI), economic (EI) social management (SMI). OATMU each determined by seeking inflection point second-order derivative power function. minimum value obtained as Finally, validated comparing it with administrative villages basin. results showed 3.60 km2. This study adopted easy access basic data simplified calculation methods, provide clear generic technical support optimizing mapping.

【目的】探究生态系统服务权衡与协同耦合关系的驱动因素及其动态变化特征,对于明确生态恢复背景下社会-生态系统的互馈机制至关重要。【方法】本文以典型植被恢复区延安市为研究区,量化了2000—2020年碳固存、产水量、基流调节与土壤保持服务,采用生态系统服务综合指数(ESI)表征4项生态系统服务耦合关系;基于贝叶斯信念网络模型(BBNs)构建社会-生态驱动因素识别框架,并揭示了植被恢复以来研究区生态系统服务耦合关系的驱动因素及其变化特征。【结果】①2000—2020年延安市生态系统服务耦合关系显著改善,ESI高值区由中部向南北扩张,低值区集中在城镇周围以及北部边缘地区;但基流调节高值概率持续降低。②降水、植被覆盖度、实际蒸散发与气温对延安市生态系统服务耦合关系变化的综合贡献率达70%以上,且降水和植被覆盖度是主导驱动因素。③20年间,降水的贡献率波动减少,植被覆盖度的贡献率持续上升;概率推理表明,气候暖湿化将加剧基流调节下降的风险,而持续的植被恢复也将引起生态系统服务耦合关系优化的阈值效应。【结论】对植被恢复区开展长期监测、提高区域基流调节功能是维持植被恢复成效以应对气候变化和人类活动干扰的优先事项。
