Evaluation of pasture, based on a multicriteria approach, is an important issue for decision making in the design of sustainable farming systems. The aim was to build a state index, based on production and biological indicators of pasture in 50 paddocks of a farm estate Garcia Abajo, located on department of Cauca, Colombia. Nine variables describing incidents factors in production factors (area of pasture, pasture age, topography, trees and canopy cover), the botanical composition (legumes, weeds, grass species) and indicators of quantity and quality of pastures (forage biomass and color) was measured and ranked with the use of a multi-criteria tool. Using multivariate statistics, a typology of pastures was performed. The C1 cluster groups the 17 paddocks longer listing, while C2 corresponds to fewer paddocks, which are young pastures. C3 contains the largest number of pastures (25), which in turn have the largest area averages. C2 fuel conglomerate highest biomass production, and has the lowest percentage of spontaneous vegetation. In conclusion, the multi-criteria analysis to evaluate pastures allows the decision maker to make judgments based on different ratings, which makes diagnosis and formulating solutions, based on endogenous concerning more successful.
