Internal Renewable Water (cu Meters Per Person)

Quantity of internal renewable water resources per person per year in cubic meters. Internal Renewable Water Resources (IRWR): Long-term average annual flow of rivers and recharge of aquifers generated from endogenous precipitation. Double counting of surface water and groundwater resources is avoided by deducting the overlap from the sum of the surface water and groundwater resources.

HOW TO JOIN WITH METADATA

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

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