| Sumario: | Background and aims: The advance of the urban frontier has caused the loss of natural ecosystems. In the mountain sector of Traslasierra (Córdoba, central Argentina), the population has increased in recent years. In this work, we analyzed the advance of urbanization in Villa de Las Rosas (VLR) and San Javier-Yacanto (SJY) towns concerning their impact on native vegetation, environmental fragility and conservation category according to Law 26,331 (“Forests Law”).
M&M: Through satellite images we georeferenced all buildings before and after the promulgation of the Forests Law for VLR and SJY. Then, we analyzed the type of vegetation, the proximity to water courses/bodies, the terrain slope and the forest conservation category in which were located the buildings that appeared until 15 years after the promulgation of the Forests Law.
Results: In both towns the number of buildings doubled during the study period. More than 80% of buildings advanced at the expense of native forests; less than 15% were located on the banks of water courses/bodies, while more than a half of them were located on sloping or very sloping terrain. The proportion of buildings located in areas of high conservation value increased after the promulgation of Forests Law.
Conclusions: Urbanization advance at the expense of native forests could be due to the scarce regulation about land use at the municipal level, to tourism promotion policies, and to urban-rural migration.. |
