The difficulties associated to the
making of decisions regarding the classification of the territory in the rural
areas of our country, and the access limitations to the technologies that
support the space analysis and generation of cartographic models, have impelled
the development of efforts aiming at the implementation of a GIS that allows us
to monitor the changes and the impact of the process of modernization of the
rural space.
The economy globalization process
has directly influenced on the landuse and the rural landscape modifications in
Central Chile, and it sets demands for different ends, among which the demand
of agricultural floor to increase the surface and productivity of the so-called
export crops, as well as the satisfaction of the residential necessities (rural
housing in this case) of the agricultural workers, are an example. This last
process has been notably intensified during the last years in almost all the
rural areas next to the big cities, which has meant the loss of agricultural
soils untying a speculation in the sale and transfer of lands, as well as
transformations that directly affect the rural landscape (Pino, 2005).
In the new globalization context,
the effective economic pattern in
On the other hand, the
use of new technologies in the agriculture has allowed to incorporate new lands
to the productive processes and has facilitated the traffic from a traditional
agriculture, rather extensive, with prevalence of cereals, leguminous, chacras and vegetables, toward
fruit-bearing and vineyards, to name the most important.
From the methodological point of
view we think that the implementation of
Geographical Information System
(GIS) and the cartography elaboration with the support and use of satellite images, will facilitate the
study of these space transformations, contributing to the understanding of
these changes; something which will allow government authorities to visualize
what could be future tendencies that will have to contemplate to take the
appropriate political measures by means of an informed territorial planning.
