Abstract
The human ownership of area causes transformations that can be accompanied and identified by
means of land use, delineation of areas of environmental conflicts and categories of hemeroby.
The objective of this work is examine the dynamics of occupation of the land use in Cará-Cará
hydrographic basin located in municipal district of Ponta Grossa, in Parana State – Brazil,
between the years 1980 and 2007, and the relation of laws in force with the land use. It was
necessary to search and draw up maps of relevant legislation, of slope and land use that were
overlay until they reach to maps synthesis of conflicts land use. As for land use, the urban class
increased (121.83%) due to the increase in population. Areas that are in conflict regarding the
use represent 21.05%. Classes of hemeroby showed that the landscapes more artificial than
natural occupy 41.94%. It was concluded that the changes in Cará-Cará hydrographic basin
were motivated by guidelines of the Municipal Master Plans.
Keywords: Hydrographic basin, Environmental conflicts, Land use, Hemeroby
1. Introduction
The changes caused by human activities in space can be monitored and verified through a
survey of land use, the delimitation of areas of environmental conflicts and the identification of
areas that suffered most changes in their natural characteristics.
When dealing with topics and themes used in environmental planning, Santos (2004, p. 97)
states that land use is a basic theme, it "portrays the human activities that can create pressure on
the natural elements" which describes "not only the current situation, but recent changes and
history of occupation of the study area".
According to Clawson & Stewart (1965), land use refers to human activity on land, which is
directly connected to earth. With the same thought Campbell (1997) states that land use are the
human activities on land held as needed, and the results of these activities are physical changes
that transform the environment.
There is need for strategies to maintain balance and dynamics of natural ecosystems present, for
example in hydrographic basin. These strategies can be implemented and controlled by
legislation, such as the Municipal Master Plan and the Forest Code to address the Permanent
Preservation Areas. The occupation of these areas with other uses generates so-called
environmental conflicts.
According to Rocha (1997) environmental conflicts in land use occur when agricultural
