Sri LankaArea equipped for irrigation increased from 457 200 ha in year 1980 to 570 000 ha in year 1995 and was assumed to be constant at this level until year 2011 LK01. Subnational information on total area equipped for irrigation was not available. Area equipped for irrigation was estimated therefore at the division level based on the irrigated paddy land extracted from an inventory related to year 2010 LK02 and an inventory of irrigated land for crops different from paddy rice for each district related to season 1990-1991 LK03.

Total irrigated paddy rice area was 556 630 ha while the area of other irrigated field crops was 60 916 ha in season 1990-1991 and then scaled to the area of 44 100 ha reported for year 2006. Total area equipped for irrigation estimated this way was 600 730 ha. The irrigated area by district is visible in the table below and the irirgtaed area both by district and by division can be downloaded as or (two sheets).The locations of 308 major irrigation schemes (more than 40 ha) and 12 lift-irrigation schemes covering 246 700 ha in total were digitized from an irrigation map LK04. The rest of the irrigated area was assigned to paddy areas as digitized from a land-use map LK05, from another map with a higher resolution but dating from 1972 LK06, and from a map that was part of the 1976 Water Resources Development Plan LK07. In divisions where area equipped for irrigation was larger than the sum of area in the registered irrigation schemes and the digitized paddy fields, the remaining difference was assigned to pixels classified as cropland by Globcover regional landcover classification for Central Asia LK08.Area equipped for irrigation with groundwater was computed based on statistics on the use of agrowells collected by the agricultural census 2002 LK09 (Department of Census and Statistics, 2009).

It was assumed that the maximum of area irrigated by agrowells in the Maha 2001/02 and the Yala 2002 seasons reported for each district represented the area irrigated with groundwater (6 828 ha in total). Area actually irrigated was 462 500 ha in year 2006 but subnational information on areas actually irrigated was not available. ReferencesLK01: FAO.
