La matriz de Leopold en EIA:

Como ejemplo de uno de los métodos que se emplean en loe Estudios de Impacto Ambiental es la llamada “matriz de Leopold” que fue el primer método utilizado para hacer estos estudios, en 1971, por el Servicio Geológico de los Estados Unidos.
Este sistema utiliza un cuadro de doble entrada (matriz). En las columnas pone las acciones humanas que pueden alterar el sistema y en las filas las características del medio que pueden ser alteradas. En el original hay 100 acciones y 88 factores ambientales, aunque no todos se utilizan en todos los casos.
Cuando se comienza el estudio se tiene la matriz sin rellenar las cuadrículas. Se va mirando una a una las cuadrículas situadas bajo cada acción propuesta y se ve si puede causar impacto en el factor ambiental correspondiente. Si es así, se hace una diagonal. Cuando se ha completado la matriz se vuelve a cada una de las cuadrículas con diagonal y se pone a la izquierda un número de 1 a 10 que indica la magnitud del impacto. 10 la máxima y 1 la mínima (el 0 no vale). Con un + si el impacto es positivo y – si negativo. En la parte inferior derecha se califica de 1 a 10 la importancia del impacto, es decir si es regional o solo local, etc.
