APPENDIX III: THE BATTELLE ENVIRONMENTAL EVALUATION SYSTEM VALUE FUNCTIONS Dr. Victor M. Ponce The Battelle EES value functions are determined by judicious analysis and knowledge of the parameters, their scope, and local situation. Lack of relevant data for most parameters precludes a more detailed assessment. 1.  Terrestrial browsers and grazers No significant reduction in grazing area is expected at La Calzada, where most of the current use is agricultural. However, a significant reduction in grazing area is expected at Calicantro. The assigned values are from Vi,0 = 1.0 to Vi,1 = 0.4. Therefore, the weighted value for the entire project is: V1,0 = 1.0 to V1,1 = 0.7. 2.  Terrestrial crops The surface area of terrestrial crops will increase substantially with the project, but some crops will be lost to inundation.
