Irrigated Villages

The vast majority of Irrigated Villages is used for cultivation of crops (median = 69%).  Net primary production is low hence we find that at least some land is used for pasture in most areas designated as irrigated villages.

As with other village anthromes most irrigated villages are found in Asia, more than 61%. 

Among irrigated villages half of the areas experience average annual temperatures between 22.5°C and 29.1°C, but more than half receive less than 1000mm of precipitation per year, which necessitates irrigation from local waterways.
