CEC Cropland Index Model (Classified)

<p style='margin:0in; font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px;'></p><p><span style='color:black;'>For lands used to produce crops, CEC developed a suitability
model to simultaneously evaluate several factors that impact an area’s relative
implication for croplands. In
the CEC land use screens, <i>implication</i> is defined as a possible
significance or a likely consequence of an action. For example, planning for
energy infrastructure development in areas with more factors that support
high-value croplands has <i>implications </i>for opportunities to preserve
agricultural land. The variables
used in the CEC Cropland Index Model contain information on soil quality (CA
Revised Storie Index, Electrical Conductivity, and Sodium Adsorption Ratio),
farmland designations (Prime Farmland, Unique Farmland and Farmland of
Statewide Importance), and current existence of crops (as indicated by the
California Statewide Crop Mapping). The
CEC Cropland Index Model does not include statewide information for
grazing lands or rangelands, and it is only applied to solar technology.</span></p>

<p><span style='color:black;'>Each input data layer is transformed onto a common scale
and weighted according to each dataset’s relative importance. The result is a
summation of the input data layers into a single-gridded map. This final model
output provides a numerically weighted index of importance for croplands
at a given location. The classified version of the model output, given in
this dataset, partitions the CEC Cropland Index Model at the mean into areas of
high and low implication. The high implication area is used as an exclusion in
the CEC Land Use Screens for solar technology. These regions have a relatively
higher implication for cropland than the lower implication region.</span></p>
