Land use change caused by human activities, has an influence on natural processes such as ground water recharge, run off, soil loss; hence the importance of understanding the dynamics of such change and its possible origins. The area of study with 22 710 ha includes the north of the municipality of Leon, Guanajuato, and the common area that it describes with the south of the Natural Protected Area Protected (NPA) Sierra de Lobos. The objective of this work consisted of determining the change of land use from 1970 to 2007, through monoscopic interpretation, associated with activities that the man realises within the NPA Sierra de Lobos. The results show that in the study area, product of the human activities, has a diminution of 10.5% of agricultural surface of agriculture from 5525 to 2395 has mainly by abandonment of parcels; of opposite way, the surface of scrubs and pasture induced has been increased with a rate of annual change of 10.9 and 68.4 ha yr-1, the previous thing due to the extensive pasturing that predominates in 85% of the producers of the area. In the studied period and area, 80 ha were developed of urban zones and the water bodies were increased 6 times in surface, with the difference that in 1970 existed 27 water bodies compared with 506 in 2007.

Keywords : human activities; monoscopic interpretation; rate of annual change.
