GoKawiilStudy finds world's protected-area coverage higher than official figures show
Researchers built a sampling method covering 10% of the world's land area, selecting sites based on ten factors including biomes, elevation, government effectiveness, income levels and population density, broken into 89 distinct features. Using the Marxan conservation-planning software, they identified a representative sample of countries and territories to measure how much land is actually under conservation protection, building on an earlier study's methodology.
GoKawiil's interpretation of the reporting above, not reported fact.
The approach suggests that official global tallies of protected land may understate true coverage, since they often rely on incomplete reporting by national governments to international databases. A more representative sampling method could give policymakers and conservation groups a clearer, independently verified picture of progress toward global biodiversity targets, such as the international pledge to protect 30% of land and sea by 2030.
- Researchers sampled 10% of global land area across 89 features spanning ten factors like biomes, elevation and income levels
- The method used Marxan software to select a representative, minimal set of countries for detailed data collection
- Findings indicate actual conservation area coverage worldwide is larger than previously estimated figures suggest
