ABSTRACT 
The coming of the European colonizers in Latin America caused an increasing reduction in the native Indian 
population, thus extinction was almost achieved in the beginning of the XX!h century. Thought a small 
community of Kaingang Indians was still living as usual in the State of Parana in the southern part of Brazil. 
In the twenties this place became, for economic reasons, very attractive. Its climate and its soil were naturally 
favorable to the development of a large scale farming. Then the transformations of landscapes began with the 
cultivation of coffee and went on into the sixties with the soja and the practice of mixed farming that caused 
important social problems in the Kaingang Indian community. This situation could have become worse after 
the municipal decision to build a tourist center in the Kaingang Reservation, but the Indian community was 
supported with popular demonstrations, so the project had to be stopped. An analysis of the deterioration of 
landscapes in the Kaingang Reservation was carried out from 1970 to 1993 with remote sensing data. 
Different image processes, either from LANDSAT TM data and aerial photographs have been carried out to 
show the spatial conflict between Indian and farmers through the extension of farming areas as well as in the 
reservation edges as in its center.
