Pavimentando Roraima: a BR-174 como exemplo das lógicas neoliberais de transnacionalização do território na Amazônia Ocidental

Este artigo discute a pavimentação da BR-174 na metade da década de 1990 e as suas consequências socioespaciais no estado de Roraima. O caso é apresentado como um exemplo da transformação das intervenções territoriais na Amazônia no contexto da neoliberalização do Estado e da produção de um espaço econômico transnacional. Os investimentos federais para o desenvolvimento rodoviário e infraestruturas auxiliares trouxeram conectividade sem precedentes para o estado de Roraima, além de gerar crescimento econômico. Todavia, o artigo argumenta que, além dos novos discursos de desenvolvimento regional sustentável, as lógicas dominantes dos projetos, tais como o melhoramento da BR-174, são as de um neoliberalismo em expansão transnacional, no qual o Estado empreendedor torna-se um parceiro para o estabelecimento de mercados externos mais do que o principal agente da integração do território nacional. Assim, no desenho da BR-174, Roraima aparece, principalmente, como um espaço estratégico de conexão transfronteiriça que liga a Amazônia brasileira aos portos do Caribe. Entretanto, passada mais de uma década desde a conclusão do projeto, a concentração territorial tem se aprofundado ao passo que emergem novas desigualdades socioespaciais intimamente atreladas às funções e fluxos que a integração rodoviária criou.

Survey of Trachoma within School Students in the State of Roraima, Brazil

Purpose: Trachoma, a blinding conjunctivitis, is the result of repeated infection with Chlamydia trachomatis. There are no recent data for the state of Roraima, Brazil, where it was thought that trachoma no longer existed. These data are derived from school children sampled in this state, with additional data collected from the contacts of children with trachoma. Design: A population-based cross-sectional study with random sampling of students in grades 1 through 4 of all public schools within municipalities where the human development index was less than the national average in 2003. The sample was stratified according to population size. Participants: A sample size of 7200 was determined and a total of 6986 (93%) students were examined, along with an additional 2152 contacts. Methods: All students were examined for trachoma according to World Health Organization criteria. Demographic data and contact information also was collected. The family and school contacts of students with trachoma then were located and examined. Main Outcome Measures: Prevalence and grade of trachoma, age, gender, race, and municipality location. Results: The overall prevalence of trachoma was 4.5% (95% confidence interval [CI], 3.7%–5.3%), but there were municipalities within the state where the prevalence of inflammatory trachoma was more than 10%. The prevalence was greater in rural areas (4.9%; 95% CI, 3.7%–6.0%) compared with urban areas (3.9%; 95% CI, 2.9%–4.9%). Living in indigenous communities was associated with trachoma (odds ratio, 1.6; 95% CI, 0.9 –2.6). An additional 2152 contacts were examined, and the overall trachoma prevalence was 9.3% (95% CI, 8.1–10.5). Conclusions: Trachoma continues to exist in Roraima, Brazil, where there are municipalities with a significant prevalence of disease. The indigenous population is highly mobile, crossing state and international borders, raising the possibility of trachoma in neighboring countries. Trachoma prevalence among the contacts of students with trachoma was higher than the school population, highlighting the importance of contact tracing.
