Overview
Widespread conversion of rural lands to urban uses has drawn
attention at all levels of government. To provide information useful
for projections of future changes in land use, ERS has created a
system to classify remaining farmland into "population-interaction
zones for agriculture" (PIZA). These zones represent areas of agricultural
land use in which urban-related activities (residential, commercial,
and industrial) affect the economic and social environment of agriculture.
In these zones, interactions between urban-related population and
farm production activities tend to increase the value of farmland,
change the production practices and enterprises of farm operators,
and elevate the probability that farmland will be converted to urban-related
uses. More overview...
