This collection provides a snapshot (year 1999-2000) of district-wise rice cropping areas for India. It is based on a compilation and analysis of 6 census-type datasets, and provides area estimates for a number different rice-based cropping systems (e.g., rice-rice-potato, rice-oilseed-fibrecrop, rice-wheat, rice-rice, rice-fallow, etc). For each of these, the area is split into two categories, irrigated and rainfed, referring to the rice crop water management only. The collection also includes estimates of monthly district-wise paddy-rice irrigation water use, based on area, soil properties, climatology data, and a water balance model. Data are table-based.
