PLAZAS CERTUCHE, Julián Andrés; DE J. LEMA TAPIAS, Álvaro  e  LEON PELAEZ, Juan Diego. A STATISTICAL PROPOSAL FOR ENVIRONMENTAL IMPACT ASSESSMENT OF DEVELOPMENT PROJECTS. Rev. Fac. Nac. Agron. Medellín [online]. 2009, vol.62, n.1, pp.4937-4955. ISSN 0304-2847.

Environmental impact assessment of development projects, is a fundamental process, which main goal is to avoid that their construction and functioning, lead to serious and negative consequences on the environment. Some of the most important limitations of the models employed to assess environmental impacts, are the subjectivity of its parameters and weights, and the multicolineality among the variables, which represent high quantities of similar information. This work presents a multivariate statistical-based method that tries to diminish such limitations. For this purpose, environmental impact assessment, is valuated through different environmental impact attributes and environmental elements, synthesized in an environmental quality index (ICA in Spanish). ICA can be applied at different levels, such as at a project level, or applied only at a partial level on one or some environmental components.

Palavras-chave : Environmental impact assessment; environmental impact attributes; environmental elements; environmental components; principal components analysis; cluster analysis; discriminating analysis.
