A.C.R. de Oliveira & S.M. Carvalho 2010. Urban tree inventory and socio-economic aspects of three villages of Ponta Grossa
615
This research aims to analyze the current context of the afforestation of public roads from
villages Esmeralda, Jardim Carvalho and Vilela in Ponta Grossa, identifying native and exotic
species present, and also examine the afforestation as a reflection of the socio- economic aspects
of population.
2. Characterization of study area
Ponta Grossa, located under the average elevation of 975 meters, is included in the
Second Paraná Plateau in the east-central region of Parana State, being an important road and
rail junction of the state. (IBGE, 2008).
The Jardim Carvalho is located in the northeast of the city and houses within its limits
thirteen villages. Were chosen as the spatial area of the district three villages, namely:
Esmeralda, Jardim Carvalho and Vilela. We opted for these three towns they are
demographically more concentrated and have vast socio-economic disparities, and were the
closest to the downtown area.
The three villages comprising 11 census tracts, which total, according to IBGE (2000),
6971 inhabitants, with 2007 inhabitants in the village Jardim Carvalho, 602 in the village
Esmeralda and 4362 in Vilela.
As one of the objectives of the research was to investigate the relationship of urban
environmental quality (through the indicator of urban forestry) with socioeconomic indices, data
from the 2000 census were prevalent for the analysis. We selected some variables that
characterize the people responsible for permanent private homes - such as education and income
- and to those which have stressed the social inequality between the villages Esmeralda / Jardim
Carvalho and Vilela.
Looking at Figure 1 it is noted that the rate of people with lower educational level is
higher in Vilela, and 2% of the illiterate population, while in villages Esmeralda and Jardim
Carvalho that number drops to 0.3 and 0.2, respectively . The variable 'Course highest attended -
College' was the one that showed the difference between the two groups this census: Jardim
Carvalho and Esmeralda has more than twice as many people with this level of education
compared with Vilela. It should be noted that this village has 1,700 people more than the other
two villages, thus demonstrating how low is that index.
Thus, from the variables ‘Course highest attended – College’ and '15 years of study' is
possible to conclude that the villages Esmeralda and Jardim Carvalho have better rates of
schooling than Vilela.
