Malaysia

Total area equipped for irrigation is 362 687 ha [MY01]. The figures refer to 1994. Irrigated area per state was available for 1993 and totalled 321 696 ha [MY02]. Therefore, irrigated area per state was scaled so that the sum was equal to the value given by the AQUASTAT report for the entire country. The irrigated area per state estimated that way is visible in the table below and also can be downloaded as Malaysia irrigation areas in PDF or Malaysia irrigation areas in Excel.

The boundaries of nine large, government irrigation schemes, designated as granary schemes and totalling 210 552 ha, were digitized from maps provided by the Department of Irrigation and Drainage [MY03]. The remaining part of the irrigated area was assigned to a large number of small-scale irrigation schemes as digitized from another irrigation map [MY04].

Area equipped for irrigation with groundwater was 27 260 ha in year 1994 [MY01]. Subnational statistics on the fraction of groundwater use were not available. The fraction of the area equipped for irrigation that is actually used for irrigation was not reported. However, the because of the high cropping intensity on the full control irrigated area (140 percent in year 1996) it was assumed that the all area equipped for irrigation is actually irrigated.
