In this article -the result of a research work sponsored by Universidad del Cauca- several environmental actions from rural coffee-coca growing communities are assessed in Miranda, Cauca. For this purpose, a participative rural evaluation and an econometric analysis were conducted through multivariate regression models estimated through the White's Robust Ordinary Least Squares. Results show that, in relation to use and control of water and soil in both cultivations, water supply actions for agriculture mostly depend on isolation actions of water springs and handling of plant and organic areas in the soil. Tree exploitation actions mostly depend on reforestation actions and connections between forested areas at the farm. Coffee-coca growing countrymen's practices are more sustainable than those of coffee growing countrymen who do not grow coca at all.
