This indicator measures the area (in hectares) actually brought under restoration -and counted toward the Bonn Challenge Commitment- in each country.
Reported hectares under restoration are divided into three tiers to convey the level of confidence and accuracy in the reported figures:
- Tier 1 values offer low confidence in accuracy, derived from non-spatial country statistics and broad estimates with limited supporting documentation or ground validation.
- Tier 2 values offer moderate confidence in accuracy, derived from maps, surveys and other statistical data with some supporting documentation and ground validation.
- Tier 3 values are associated with high confidence in accuracy, derived from spatially-specific estiamtes supported by adequate documentation and ground validation.
