Biomass Stock In Forest (tonnes/ha)

Biomass stock refers to organic material both above-ground and below-ground, and both living and dead, e.g., trees, crops, grasses, tree litter, roots etc.; including the pool definition for above- and below-ground biomass in forest; other wooded land not included.

HOW TO JOIN WITH METADATA

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

• 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.biomass_stock_in_forest_tons AS value
FROM @gapminder.biomass_stock_in_forest_tons.biomass_stock_in_forest_tons_by_geo_time d
LEFT JOIN @gapminder.metadata.entities_geo_country c ON d.geo = c.country;
