Abstract

Versão traduzida do artigo “The risk of fake controversies for Brazilian environmental policies”, publicado no periódico Biological Conservation, v. 266,em fevereiro de 2022. Disponível em: < https://doi.org/10.1016/j.biocon.2021. 109447>.Tradução de Evandro L. T. P. Cunha e Letícia Santos de Lima. Falsas controvérsias têm influenciado a elaboração de políticas sobre questões ambientais e de saúde há décadas, resultando em grandes retrocessos na implementação dessas políticas em todo o mundo. Utilizando um estudo de caso, neste artigo são examinadas falsas controvérsias produzidas por um pequeno grupo de pesquisadores brasileiros que têm afetado seriamente a conservação ambiental, particularmente em questões relacionadas ao desmatamento e às mudanças climáticas. Com base na literatura, foi desenvolvida uma tipologia das estratégias empregadas em falsas controvérsias, que incluem a fabricação de incertezas, o uso indevido de credenciais científicas e a desconsideração da literatura científica. Posteriormente, foi examinada a influência desse grupo de negacionistas no Congresso Nacional. Analisam-se, então, as falsas controvérsias promovidas por esses negacionistas e argumenta-se que, para entende-las adequadamente, é necessário considerar uma estratégia até agora negligenciada na literatura: a criação de “pseudofatos”, ou seja, afirmações em desacordo com a literatura científica já estabelecida, mas que são mascaradas para parecerem fatos científicos. Ao contrário de outros contextos, nos quais os negacionistas têm procurado principalmente lançar dúvidas sobre questões já consensuais, argumentando que ainda existem incertezas consideráveis em torno delas, no Brasil foram produzidos e publicados pseudofatos sobre o desmatamento fora do âmbito da literatura revisada por pares. Concluímos o estudo com recomendações sobre como se opor às falsas controvérsias científicas que ameaçam a conservação ambiental em geral.

29. Cronologia e impacto ambiental do uso da terra na Microbacia Hidrográfica do Ceveiro, em Piracicaba, SP

Abstract

Este trabalho objetivou avaliar a cronologia e o impacto ambiental do uso da terra na Microbacia Hidrográfica do Ceveiro (MHC), nos anos de 1962, 1965, 1978 e 1995. Utilizou-se a fotointerpretação e geoprocessamento, o que permitiu uma rápida e eficiente integração entre os dados levantados. Os solos da área são basicamente Litossolos e Podzólicos Vermelho-Amarelos. A cultura anual, que em 1965 chegou a ocupar 42% da área da microbacia, em 1995 ocupava 0,15%. Nesse mesmo período, o plantio da cana-de-açúcar passou de 16% para 66%, sendo esta cultura a principal causa da diminuição das culturas anuais na microbacia. O maior aumento do plantio da cana-de-açúcar ocorreu de 1978 a 1995, caracterizando, assim, a influência dos incentivos governamentais para o seu cultivo. As pastagens e os reflorestamentos também contribuíram para a expansão do plantio da cana-de-açúcar, com uma diminuição em área de 48% das pastagens e 42% do reflorestamento. As áreas de mata nativa e urbana apresentaram um aumento de 1962 a 1995. O impacto ambiental na MHC tem como indicador a represa da Vila de Artemis, que, de 1978 a 1995, diminuiu sua área em 50%, em decorrência do assoreamento.

30. Learning soil classification with the Kayapó indians

Xicrin do Cateté, Amazon, Brazil, indigenous knowledge, Agriculture (General), S1-972
Abstract

The Kayapó Xicrin do Cateté (Xicrin) indigenous reserve is located within the Amazon forest in Pará (Brazil). The Xicrins have developed a soil classification system that is incorporated in their language and culture. The etymology of their classification system and its logical structure makes it similar and comparable with modern soil classification. The etymology of the Xicrin's language is based on the junction of radicals to form words for different soil names. The name of the soil is formed by the main noun radical "puka", to which adjectives referring to soil morphological attributes are added. Modern classification systems are also based on similar morphological variables, and analytical support for defining boundaries of chemical or physical soil attributes are important only in lower hierarchical levels. Soil scientists have developed a soil classification system that is sensitive for the restrictions and potentialities the soil will show for modern agriculture. The Xicrins classify soils for what is important for their life style, i.e. a harmonic and friendly life with the resources they gain from the forest.

35. A national soil profile database for Brazil available to international scientists

Subjects

Abstract

A comprehensive digital soil profile database of Brazil was compiled and is being made available through the Internet. Most of the soil data were obtained from the Radambrasil project and other regional surveys. The database contains information from 5086 profiles distributed over the whole Brazilian territory corresponding to data from 10 034 horizons, each with 31 variables. The variables were chosen to represent different areas of soil science, embracing soil morphological, chemical, mineralogical, and physical attributes. The distribution uniformity of the data was low with sampling densities varying from one profile per 10 000 [km.sup.2] to one profile per 1370 [km.sup.2]. The access to the database is free and its design allows its use not only by soil scientists but also by those working with agricultural, environmental, and land use issues.

Abstract

Results show that the response of the bacteria to carbon sources in the soil samples, collected from a soil reclamation gradient, manifests in terms of an increase in the number and diversity of the bacteria, which exhibit highest functional redundancy for the substrates found in the preserved forest soil.
