Abstract
An Environmental-Impact Assessment (EIA) makes it possible to determine whether or not a project is compatible with nature, and thus whether the project qualifies to be executed. The Environmental-Impact Assessment is intended to establish a balance between the development of human activities and the environment. In this work, an Environmental-Impact Assessment of the mineral deposit of Punta Gorda (Moa, Cuba) is made, using fuzzy techniques. Two previous works have been combined: an appropriate linguistic model built with fuzzy techniques, providing a framework for handling qualitative and quantitative variables, and an environmental-impact assessment carried out according to a classical methodology.
