Note Difference between Total Land Use (1) and Rainfed Use (2), is Irrigated Use (3), so 1
= 2+3. Crop intensity is the ratio between Harvested and Cultivated
Land, so H/C
= CI
Source by the author, based on date of FAO (2011)
Definition
The fraction of the cultivated area that is harvested. The cropping intensity may exceed 100 percent where more than one crop cycle is permitted
each year on the same area. In AQUASTAT, the cropping intensity has been calculated on irrigated crops only and becomes practically the ratio of the harvested
irrigated areas over the area equipped for full control irrigation actually irrigated. Irrigation, by decoupling the crop production from the natural precipitation,
increases cropping intensity in countries where temperatures are not a limiting factor. Source: http://www.fao.org/nr/water/aquastat/data/glossary/search.html?
