Agricultural Water Withdrawal (% Of Total)

Percentage of the total water withdrawal used in agriculture, including renewable freshwater resources as well as potential over-abstraction of renewable groundwater or withdrawal of fossil groundwater, use of agricultural drainage water, desalinated water and treated wastewater. It also includes water withdrawn for irrigation purposes and for livestock watering, although depending on the country this last category sometimes is included in municipal water withdrawal. As far as the water withdrawn for irrigation is concerned, the value far exceeds the consumptive use of irrigation because of water lost in its distribution from its source to the crops.

HOW TO JOIN WITH METADATA

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

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