Machine Learning Analysis Reveals Deforestation Risks in Pakistan's Semi-Arid Regions

Researchers at Beijing Forestry University have conducted a study using machine learning and remote sensing to analyze deforestation and fragmentation dynamics in Pakistan's semi-arid regions between 2001 and 2021. The research found that deforestation and forest degradation in these regions drive critical environmental challenges. The study used multi-source remote sensing data, Google Earth Engine (GEE), and machine learning algorithms (Random Forest and Extreme Gradient Boosting) to assess the impact of human activities on forest ecosystems.

Key Takeaways:

  • The study achieved high accuracy in land use/land cover classification, with Random Forest achieving 94.81% overall accuracy and XGBoost demonstrating 90.17% accuracy in spatial fragmentation analysis.
  • The net forest cover increased by 3.48% between 2001 and 2021, but structural fragmentation intensified, with a 3.4% increase in edge forests and a 2.9% rise in isolated islets.
  • High-risk deforestation zones (9.09% of the landscape) were concentrated near urban-agricultural frontiers, driven by road proximity and elevation.
  • Urban areas expanded by 20.2% between 2010 and 2021, displacing cropland and barren land, which declined by 1.94%.
  • Morphological Spatial Pattern Analysis (MSPA) revealed persistent connectivity loss, with core forests representing only 3.51% of the study area.
  • The research concluded that conservation strategies prioritizing landscape connectivity and mitigating connectivity-based degradation are necessary in semi-arid regions.
