Abstract:

The study area is La Colacha sub‐basins from Arroyos Menores basins, natural areas at West and South of R&iacuteo Cuarto in Province of Córdoba of Argentina, fertile with loess soils and monsoon temperate climate, but with soil erosions including regressive gullies that degrade them progressively. Cultivated gently since some hundred 60 years coordinated action planning has become necessary to conserve lands while keeping good agro‐production. Some of the authors were engineers trained here and other had former experience in Salta, Argentina, using a set of Decision Theory Methods, (DTM), to consider the possible systems of soil uses and actions to be recommended. After having improved data on soils and on hydrology for the study area, they have adapted as academic study these DTM for Arroyos Menores areas where gully erosions are severe, also intending to offer better view for the necessary planning to have policies of actions and uses, done by the local society decision and services, and in part by land owners. This paper concentrates on the application of a set of discrete multi‐criteria models (MCDM), where alternatives were global, considering soil conservation and hydrologic management actions, and main types of use of soil, and where criteria were about the diverse consequences, grouped as environmental, economic, and social. As methods they have used for the sub areas PROMETHEE with sets of weights, comparing results with ELECTRE with same data and weights, and with AHP method needing comparisons of criteria by authors, getting somehow compatible results, but finding that the ‘weighted PROMETHEE II’ was the more adapted for the present study. The system and results are very global, and are offered as indications for planning, that will require using detailed engineering and administration aspects for series of local singular actions or for management pursued in time.
