The document compares two multicriteria decision methods - Brans' PROMETHEE and a modified version - for selecting erosion control alternatives in Argentina's Chaco area. It applies the methods to choose among five alternatives (forestation options and agriculture/livestock mixes) across six subzones. Eight criteria are considered, including water/wind erosion, economic/social impacts. The modified PROMETHEE method weights criteria similarly to ELECTRE I. Results show alternative rankings for one subzone using both methods, with some alternatives preferred over others.
