METHODOLOGIES

The rules behind recommendations

Each recommendation comes from a stated rule with evidence numbers, a calculation note and a priority.

Advanced 1 min read recommendationsrulesintelligencepriority

Atlas generates recommendations for every country with a mangrove map. Each is produced by a transparent rule.

Examples of rules

  • Net change. Net loss of ≥5% since 1996 is high; any loss is medium; gain is low.
  • Fragmentation. Many tiny patches with most area in a few large stands suggests focusing on the large stands and checking the small-patch tail.
  • Pressure. More than 30% of mangrove within 10 km of a major development is high (Lamu).
  • Validation. Low agreement between field plots and the map is high.
  • Governance. Datasets with no stated licence raise a licence recommendation.

Each recommendation stores a category, priority, confidence, evidence (the numbers that triggered it), the calculation and a suggested action. They are regenerated whenever the data changes.

Honest limits. The rules encode judgement about what is worth flagging. They are transparent, but not exhaustive.

Limits. Rules are tuned for mangrove screening, not for legal or financial decisions.
