Show PAET V ALTERNATE LEVELS OF DEVELOPMENT Summary Agriculture in this region is tied to irrigated cropland production; therefore, the increase in production on existing irrigated lands by im- proved management practices and supplying supplemental water and the de- velopment of newly irrigated land relate to a large portion of the agri- cultural activity. Projected irrigated acreage for the alternative levels of development by time frame is shown in Table 46.

The "Regionally Interpreted" OBERS described in this appendix appraised crop production needs consistent with livestock output projections by utilizing the region's resources and determined an irri- gated acreage requirement. The two approaches lead to different estimates 02' irrigated acreage requirements, as indicated in Table 47« Table 47 - Comparison of projected irrigated acreage requirements between OBERS "as Published" and the "Regional Interpretation," 1965 to 2020 __________________(Unit-1,000 acres) Year OBERS "as Published" 1965 1,621.5 1980 1,498.7 2000 1,529.2 2020 1,550.8 Difference- 1965-2020 -70.7 OBERS "Regional Int erpret at ion" Differ- ence 1,621.5 1,793.6 1,954.2 2,122.1 +500.6 0 294.9 425.0 571.3 90 |
