The impact of social and economic development on local ecological patterns should not be ignored. Because human beings cannot change the natural environment quickly, it is only by paying attention to research factors that we can promote implementation policies. From perspective economics, this paper selects panel data for 31 provinces in China during 2000–2020 explore differences influencing different socioeconomic stages using spatial Durbin model piecewise regression method. We found distribution ecosystem service value per unit area uneven, being high east low west, south, north. At development, capita GDP, proportion primary industry, tertiary industrial pollution control investment, population density, construction land area, total investment key forestry projects, education infrastructure road length have impacts value, even spillover effects adjacent areas.

Growth and diversification of tourism activities in Antarctica have not been matched by proactive strategies for planning or management. Recognizing that the adaptive management approach has effectively implemented managing protected areas, we examine to what extent this incorporated into Antarctic research management, constraints exist its implementation. To better understand literature contributions, conducted an appraisal 72 peer-reviewed journal articles published from 1992 2020 documents. From a scientific perspective, researchers advocating approaches applied different elements, particularly ecological assessments, design measures, monitoring, regulatory mechanisms. However, these contributions necessarily translated policy regulations. We acknowledge full implementation is easily achievable due unique regime. argue comprehensive site-specific regional models could be as first step more systematic This incremental contribute enhanced stakeholder participation improved decision-making processes, ultimately leading effective tourism, essential conservation continent.

Across the high seas, distant water fisheries have benefited from government subsidies. Public funds directed toward supporting fishery sector enabled these to extend their range and duration at sea, threatening fish populations health of ocean ecosystems. Fuel subsidies been identified as primary form subsidy, often allowing fishing vessels continue operations despite declining revenues. While significant attention has understanding on a global scale, magnitude specific Southern Ocean remained largely unknown. The accounts for 10% oceans, its two main fisheries, Antarctic krill toothfishes, are managed by Commission Conservation Marine Living Resources (CCAMLR). Through data collection in interviews, our study provides comprehensive analysis complex that underpin fisheries.

Antarctica harbors many distinctive features of life, yet much about the diversity and functioning Antarctica’s life remains unknown. Evolutionary histories functional ecology are well understood only for vertebrates, whereas research on invertebrates is largely limited to species descriptions some studies environmental tolerances. Knowledge Antarctic vegetation cover showcases challenges characterizing population trends most groups. Recent community-level microbial have provided insights into at its limits. Overall, biotic interactions remain unknown across all groups, restricted basic information trophic level placement. Insufficient knowledge groups limits understanding ecological processes continent. Remedies current situation rely identifying caveats each discipline finding targeted solutions.
