Area equipped for irrigation for the seven regions (1 045 131 ha in total) was derived from a melioration inventory related to year 2005 [KG01]. To estimate area equipped for irrigation for each of the 40 districts an inventory for year 1994 was used [KG02]. AEI reported in this inventory for each district (1 075 040 ha in total) was scaled so that the sum of AEI in each region was similar to the AEI reported in [KG01] for year 2005. The irrigated area per district estimated that way is visible in the table below and also can be downloaded as Kyrgyzstan irrigation areas in PDF or Kyrgyzstan irrigation areas in Excel.
The irrigated areas were localized using a map of irrigation projects [KG03] and then digitized using satellite imagery [KG04] and a map of irrigated areas in the Aral Sea Basin [KG05]. These digitized irrigated areas were combined with irrigated cropland derived from the Globcover regional classification for Central Asia [KG06]. Irrigated area was then assigned with the highest priority to pixels being irrigated according to both data sources and after that, if required, to pixels that were either covered by the digitized irrigated areas or classified as irrigated by Globcover.
Area equipped for irrigation with groundwater was 7 000 ha in year 1994 [KG06] while area actually irrigated was 1 021 400 ha in year 2005 [KG07].
