Treadle water pumps in Africa and Asia allowed women farmers to irrigate small plots and increase their harvests and incomes.
"supply land with water," 1610s, from Latin irrigatus, past participle of irrigare "lead water to, refresh, irrigate, flood," from assimilated form of in- "into, in, on, upon" (see in- (2)) + rigare "to water, to moisten," of uncertain origin, perhaps cognate with rain. Related: Irrigated; irrigating. In Middle English it was an adjective, "watered, flooded" (mid-15c.).
