The GFSAD30 is a NASA funded project to provide high resolution global cropland data and their water use that contributes towards global food security in the twenty-first century. The GFSAD30 products are derived through multi-sensor remote sensing data (e.g., Landsat, MODIS, AVHRR), secondary data, and field-plot data and aims at documenting cropland dynamics from 1990 to 2017.
Monitoring global croplands is imperative for ensuring sustainable water and food security to the people of the world in the Twenty-first Century. The currently available cropland products suffer from major limitations such as:
Thereby, the overarching goal of GFSAD30 project is to produce consistent and unbiased estimates of global agricultural cropland products such as:
1) Cropland extent\area;2) Crop types with focus on 8 crops that occupy 70% of the global cropland areas;3) Irrigated versus rainfed;4) Cropping intensities: single, double, triple, and continuous cropping;5) Cropland change over space and time: 1990-2017.
Once the above products are established, other products such as the following can be derived using the above products and certain other inputs:
6) Crop productivity (productivity per unit of land; kg\m2)7) Water productivity (crop per drop or productivity per unit of water; kg\m3).
Relevant methodology including Models and Algorithms used by the group.

The above map is an example of the 30 meter Cropland Extent products that are available for inspection on Croplands.org. Users can explore additional data sets such as 250 meter data and 1 kilometer data. Likewise, users have the ability to zoom in to examine individual pixels.
