(PDF) Mapping Irrigated Areas In China From Remote Sensing And Statistical Data Using these indices and a spatial allocation model, we downscaled the census data on irrigation from administrative units to individual pixels and produced a new irrigation map of china. Using these indices and a spatial allocation model, we downscaled the census data on irrigation from administrative units to individual pixels and produced a new irrigation map of china around the year 2000.

(PDF) Mapping Irrigated Areas In China From Remote Sensing And Statistical Data Here, we produced annual 500 m irrigated cropland maps across china for 2000–2019, using a two step strategy that integrated statistics, remote sensing, and existing irrigation. Here, we addressed these important gaps and developed new annual maps of china’s irrigated cropland from 2000 to 2020, named cirrmap250 (china’s irrigation map with a 250m resolution). we harmonized irrigation statistics and surveys and reconciled them with remote sensing data. This study proposed a novel approach to develop the first 250 m irrigated cropland map in mainland china (cirrmap250) by integrating remote sensing, irrigation suitability, and irrigated area statistics. The annual irrigation datasets allow us to understand the spatiotemporal dynamics of irrigated croplands in china and are expected to contribute to the improvement of earth system models and facilitate sustainable agricultural water management.

The annual irrigation datasets allow us to understand the spatiotemporal dynamics of irrigated croplands in china and are expected to contribute to the improvement of earth system models and facilitate sustainable agricultural water management. The maps were created using a synergy approach, which combines and integrates regional and global irrigation maps, cropland maps and subnational statistics. the maps were calibrated to subnational irrigation statistics and validated using an external dataset with geocoded information on the location of irrigated areas. We validated our new irrigation map and also two global irrigation maps (iwmi map and fao/uf map) in china using 614 reference samples including 262 irrigated samples and 352. The maps were calibrated to subnational irrigation statistics and validated using an external dataset with geocoded information on the location of irrigated areas.
