MPNPI index calculation requires four indicators: land use (LCI), runoff (ROI), distance (DI) and annual precipitation (API). The results indicate that basins categorized as ranging from medium to very high diffuse contamination potential (nonpoint source pollution potential), with spatial coincidence during the three considered years, are Chuanito, Chondo and Cutio to the northwest; San Francisco and Huandiestacato to the north; Apo and Cuenca Rodada to the west; which in turn cross physical-geographical localities XLIV, XVII and LX; such conjunction allows to delimit spaces with homogeneous environmental characteristics within the basin which, in turn, helps to prioritize units that need to implement mitigation measures against diffuse pollution of aquatic systems En este trabajo, secalculó el Índice Modificado de Contaminación No Puntual (MPNPI), en el Área de Protección de Flora y Fauna, Pico de Tancítaro, Michoacán, durante tres años con diferentes condiciones de precipitación 2004, 2007 y 2014; en esta área se encuentran 16 cuencas para la región, dentro de estas existen 10 localidades de la tipología Físico-Geográfica del estado de Michoacán. La forma de calcular el índice MPNPI requiere de cuatro indicadores: Uso del Suelo (LCI), Escorrentía (ROI), Distancia (DI) y Precipitación Anual (API). Los resultados indican que las cuencas con categorías de potencial de contaminación difusa que va del Medio a Muy alto, con coincidencia espacial durante los tres años son Chuanito, Chondo y Cutio al noroeste; San Francisco y Huandiestacato al norte; Apo y Cuenca Rodada al oeste; al interior localidades físico-geográficas, XLIV, XVII y LX, esta conjunción permite delimitar espacios con características ambientales homogéneas dentro de la cuenca, esto ayuda a priorizar unidades que requieren implementar medidas de mitigación de la contaminación difusa hacia los sistemas acuáticos Universidad Nacional, Costa Rica 2020-06-29 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Evaluado por pares application/pdf text/html application/epub+zip https://www.revistas.una.ac.cr/index.php/geografica/article/view/12262 10.15359/rgac.65-2.8 Geographical Journal of Central America; Vol. 2 No. 65 (2020): Revista Geográfica de América Central; 207 - 238 Revista Geográfica de América Central; Vol. 2 Núm. 65 (2020): Revista Geográfica de América Central; 207 - 238 Revista Geográfica da América Central; v. 2 n. 65 (2020): Revista Geográfica de América Central; 207 - 238 2215-2563 1011-484X spa https://www.revistas.una.ac.cr/index.php/geografica/article/view/12262/19546 https://www.revistas.una.ac.cr/index.php/geografica/article/view/12262/19547 https://www.revistas.una.ac.cr/index.php/geografica/article/view/12262/19548 Derechos de autor 2020 Alberto Ortiz-Rivera, José de Jesús Alfonso Fuentes-Junco
