Conversion of agricultural land to urban and low-density residential development between 1992 and 2012
The development of agricultural land is shown in relationship to the low-to-high continuum of productive, versatile, and resilient values for agricultural land. The conversion of agricultural land to urban and low-density residential uses between 1992 and 2012 is shown as high (dark brown-red, > 25% conversion within a 10-kilometer (6.2 miles) radius), moderate (light brown-red, 10–25% conversion) and low (tan, 5–10% conversion). Urban areas are shown in gray.
