Primary Forest Area (ha)

Total area of forest land (hectares) with native species, where there are no clearly visible indications of human activities and the ecological processes are not significantly disturbed.

HOW TO JOIN WITH METADATA

• Concepts (labels/units)
– Use the concept id primary_forest_area_ha to look up labels and units in @gapminder.metadata.concepts.
SELECT * FROM @gapminder.metadata.concepts WHERE concept = 'primary_forest_area_ha'.

• Countries and names
– Join your datapoints on geo to @gapminder.metadata.entities_geo_country to get readable country/area names
(e.g., name) and membership attributes such as world_4region, income_groups.

• Regions and other group labels
– After you have a region code from the country table (e.g., world_4region),
you can join to:
· @gapminder.metadata.entities_geo_world_4region on world_4region → region names/colors/shapes
· @gapminder.metadata.entities_geo_world_6region on world_6region → region names
· @gapminder.metadata.entities_geo_income_groups on income_groups → income group names

Example:
SELECT d.time,
c.name AS country,
d.primary_forest_area_ha AS value
FROM @gapminder.primary_forest_area_ha.primary_forest_area_ha_by_geo_time d
LEFT JOIN @gapminder.metadata.entities_geo_country c ON d.geo = c.country;
