Desigualdade social intraurbana: implicações sobre a epidemia de dengue em Campinas, SP, em 2014

This paper investigates whether the segmentation of social groups in the urban fabric, with differential access to the city’s resources and services, can influence the spatial and temporal distribution of dengue cases. The study’s site is the city of Campinas, state of Sao Paulo, in which we analyzed the dengue cases reported from January to December 2014. For this purpose, geoprocessing and spatial analysis tools were applied. The findings indicated that social inequality could be conditioning the distribution of dengue cases in conjunction with other factors that contributed to the occurrence of the largest epidemic recorded in Campinas so far.

Demographic transition and transition of urban water consumption in Brazil

In this paper we discuss that, although the volume of the population is an important aspect to be considered in the relationship between population and environment, there are other factors that may be even more important. From a demographic perspective, for example, details such as composition and spatial distribution of the population are essential. In environmental terms, the style of development and level of consumption are crucial. Brazil is going through a time of important transitions. On the one hand, the demographic transition (decreased levels of mortality and birth rates), is characterized by the rapid decline in total fertility rate, from about 6 children per woman in the 1960s to fewer than 2 children per woman in the late 2000s. On the other hand, there is a consumption transition also incourse, discussed here in the relationship between improving the economic situation and increased water consumption, which is caused by the expansion of the supply system in urban areas and by the trend toward growing per capita consumption. Thus, while there has been a significant decrease in population growth rates, water consumption tends to increase as the result of changes in access patterns and consumption levels.In this paper we discuss that, although the volume of the population is an important aspect to be considered in the relationship between population and environment, there are other factors that may be even more important.

Water, sanitation and health: an intra-urban comparison in the municipality of Caraguatatuba, Brazil

The rapid urbanization of Latin America during the twentieth century resulted in poor sanitation conditions that exposed its population to significant health risks. One of the most important examples is outbreaks of dengue fever, a multifactoral disease resulting in part from unsanitary water. This work seeks to understand the possible interrelation between the distribution of environmental sanitation services, including water, and the distribution of dengue by comparing intra-urban areas in Caraguatatuba, Brazil, using GIS tools such as regular grids, cluster analysis, and the application of Moran’s index.
