Farmland Mapping & Monitoring Program

Irrigated Farmland in Monterey County.

​​

Documenting Changes in Agricultural Land Use Since 1984

The Farmland Mapping and Monitoring Program (FMMP) produces maps and statistical data used for analyzing impacts on California’s agricultural resources. Agricultural land is rated according to soil quality and irrigation status; the best quality land is called Prime Farmland. The maps are updated every two years with the use of a computer mapping system, aerial imagery, public review, and field reconnaissance.
