Organization Title

Irrigated farmland losses accellerated compared with the 2002-2004 period, as steady urbanization rates combined with changing agricultural markets and resource availability factors.  Farm and grazing lands in California decreased by 275 square miles (176,014 acres) between 2004 and 2006 as documented by the Farmland Mapping and Monitoring Program (FMMP).  The highest-quality agricultural soils, known as Prime Farmland, comprised 46% of the loss (81,247 acres).  Urban development was concentrated in a smaller number of counties, resulting in an increase of 0.2% in urbanization relative to the 2002-04 period (102,010 and 101,825 acres, respectively).  2004-2006 report cover image
