Estudos de externalidades na área de saúde humana decorrentes de reservatórios hidrelétricos

Abstract

ResumoO objetivo deste trabalho foi apresentar um método para se estimarem os valores das externalidades na área de saúde associadas à operação de reservatórios hidrelétricos. O método foi aplicado nos municípios de Uberaba e Uberlândia, Minas Gerais, parcialmente alagados pelo reservatório de Miranda. AbstractThe objective of this work was to present an estimation method of the values of the health externalities associated to the operation of hydro power plants reservoirs. The method was applied in the cities of Uberaba and Uberlândia, Minas Gerais, Brazil, partially flooded by Miranda reservoir. The number of hospital admittances in the Public Health System and the population growth in the flooded municipal districts were analyzed. If there is a cause-effect relation between the lake and the diseases, the costs of externalities in 2001 were estimated in R$ 25,000 when US$ 1 corresponded to R$ 2,36; the population number linked to this value was 773.409. The economical value of the health impacts showed that they do not have much significance.

“…Ferreira et al (2011) apresentaram um método para estimar os valores das externalidades na área de saúde, associado às operações de reservatórios hidrelétricos. Foram analisados o número de internações hospitalares na rede do Sistema Único de Saúde e o crescimento populacional.…”

“…Foram analisados o número de internações hospitalares na rede do Sistema Único de Saúde e o crescimento populacional. A justificativa é que em regiões próximas aos reservatórios é comum o aumento dos casos de febre amarela, dengue, malária, esquistossomose, entre outras, portanto segundo Ferreira et al (2011) ocorre uma relação de causa e efeito entre o lago e os impactos à saúde, o custo da externalidade.…”

Hydropower, Social Capital, Community Impacts, and Self‐Rated Health in the Amazon*

“…Scudder (2012) mentions that for individuals who were resettled, it is common to see multidimensional stress (physiological, psychological, and sociocultural) associated with the displacement. In Brazil, studies have covered a wide range of dam‐associated health impacts, focusing on outcomes such as malaria (Barcellos et al 2018), syphilis, homicides and suicides (da Silva Marques et al 2018; Gristotti 2016); leishmaniasis (Ferreira et al 2011); stress, hypertension, undernourishment, respiratory problems, and alcoholism (Giongo and Mendes 2015; Rosa et al 2018). Yet, to our knowledge, this is the first analysis of the association between self‐rated health, community resources, and social capital loss in the context of large hydropower dam construction.…”

“…However, environmental changes caused by the building of dams, together with the increase in numbers of workers, usually affect outbreaks of diseases such as malaria, dengue, yellow fever, filariasis, and leishmaniasis (Kochtcheeva and Singh 1999). The installation of hydroelectric dams may affect the fauna of vector insects and, consequently, the epidemiology of the diseases they transmit, by interfering with their natural food sources, in their population density, and in the composition and dispersion of potential vector species (Ferreira et al 2011, Figueiredo 2007, Guimarães et al 1997, Paula and Gomes 2007, Rezende et al 2009).…”
