Social-ecological systems (SESs) possess a great diversity of land use and cover (LULC) types with unique assemblages biodiversity ecosystem services. However, LULC changes due to landscape fragmentation are emerging as major threats the system productivity SESs around world. This study examined extent patterns in Village Tank Cascade Systems (VTCSs) Sri Lanka using satellite imagery GIS techniques between 1994 2021. Multispectral Landsat images (5 TM 8 OLI/TIRS) obtained from Google Earth Engine were classified machine learning algorithms. Overall accuracies 85.9% (1994) 88.6% (2021). The change matrix spatial pattern metrics used examine dynamics over VTCS landscapes. results revealed that forest, which is dominant class covering 73.7% total area was reduced by 206,725 ha transformation into agricultural (70.43%) scrub (24.33%) lands Over this time has gradually changed forest land-dominated landscape, showing significant negative correlation ( p < 0.001; R 2 > 0.868), particularly southeastern region. Landscape analysed based on eight calculated at both levels FRAGSTATS analysis software. At level, structure became more dispersed complex shape. Heterogeneity noted have increased weakening connectivity, whereas process had accelerated. dominance patches decreased, isolation increased, connectivity shape complexity leading loss fragmented habitats. number within aggregated performance indicators show VTCSs experienced gradual environmental sustainability. Assessment along can help monitor impacts determine ecological integrity. Thus, provides scientific guidance for restoration degraded effectively improve productivity.

Air pollution is a major trigger for chronic respiratory and circulatory diseases. As key component of air pollution, fine particulate matter (PM2.5) exposure largely determined by land use type population density. However, simultaneous consideration their spatiotemporal distribution lacking in existing studies on PM2.5 exposure. In this paper, we first assess the dynamic evolution patterns Gansu Province, China, from 2000 to 2020, using transfer matrix degree. Population-weighted (PWE) then evaluated each at provincial, city, county levels, with seasonal variations analyzed. Spatial autocorrelation analysis finally performed explore exposure, whereas standard deviation ellipses gravity center migration models highlight spatial characteristics shifting trends. Experimental results showed that 2010 was turning point annual provincial level an initial increase followed decrease. Construction had highest forest lowest (except 2005). Exposure levels pattern: higher winter spring lower summer autumn. At city southern indicated continuous decline across all types since 2000. exhibited strong positive correlation, fluctuating convergence. This study comprehensively analyzes multi-scale differences various types, contributing provide scientific evidence decision-making support mitigating enhancing coordinated control administrative levels.

Climate and land use change pressures are critical to food production in Social-Ecological Systems (SESs). This study assessed farmers’ perceptions of the climate changes alongside their impacts on Mhahakanumulla Village Tank Cascade System (MVTCS), a SES maintained by traditional agricultural systems dry zone Sri Lanka. used both rating ranking scale questions quantify perceptions. The tobit regression model was employed evaluate how farmer perception influenced socio-economic factors. results showed that most farmers had experienced MVTCS area changed over time, they perceived variability rainfall patterns as prominent influential change. increased cost production, wildlife damage, degradation were ranked impactful factors due rated deforestation clearing use, while damage highest changes. Among determinants, training income/profit positively severity level farmer’s adaptation negative association with Household size negatively influencing impacts. spatial farm downstream locations Thus, effectiveness strategies towards depends well understood farmers. findings provide helpful insights for formulating localized policies these globally important landscapes combination top-down bottom-up approaches.
