ABORDAGEM AMBIENTAL E GESTÃO DE RESÍDUOS DE CONSTRUÇÃO: UMA ANÁLISE CURRICULAR NOS CURSOS DE ENGENHARIA CIVIL E ARQUITETURA EM PALMAS, TO

A importância da abordagem ambiental nos cursos de Engenharia Civil e Arquitetura e Urbanismo em Palmas, TO, está relacionada principalmente à sua expansão urbana e às crescentes preocupações ambientais. Esta pesquisa documental analisou as ementas e conteúdos programáticos dos Projetos Pedagógicos desses cursos. Os principais resultados indicam uma ausência de conteúdos específicos sobre gestão de resíduos de construção civil nos currículos, embora haja ênfase na dimensão ambiental. O enfoque nesta temática muitas vezes se limita a conceitos teóricos e introdutórios, abordados de forma transversal ou em disciplinas optativas. Além disso, os currículos necessitam de atualização e adaptação para atender às necessidades ambientais presentes e futuras do país. Para pesquisas futuras, sugere-se ampliar a amostra e analisar a obrigatoriedade de disciplinas ambientais em cursos de Engenharia Civil e Arquitetura, além de investigar a formação e competências dos professores que ministram conteúdos ambientais, tanto específicos quanto transversais

Symbolic Losses and the People Affected By the Construction of Dams: the Case Study of the Estreito Hydroelectric Power Plant, Brazil

Dentre as atividades econômicas em desenvolvimento no Brasil, está a construção de usinas hidrelétricas. A crescente expansão do setor elétrico vem acarretando perdas irreversíveis para as populações impactadas, em razão do seu deslocamento compulsório e consequente ruptura com o seu espaço de construção simbólica. Tendo em vista o horizonte de crescimento do setor elétrico no país, este trabalho buscou analisar como o processo de negociação das perdas simbólicas sofridas pelos atingidos por barragens vem sendo conduzido, tendo sido os dados obtidos a partir de análise documental, seguida da realização de entrevistas com os impactados pela Usina Hidrelétrica de Estreito, situada no médio Rio Tocantins, entre os Estados do Maranhão e Tocantins. Esta pesquisa evidenciou a necessidade de buscarmos mecanismos que contemplem os valores simbólicos desses atingidos, priorizando a continuidade da vida que não prima pela lógica do mercado e sim pela vivência com dignidade humana.Among the economic activities under development in Brazil it is the construction of hydroelectric power plants. The increasing expansion of the Brazilian electrical sector has been causing irreversible losses to impacted populations, due to their forced displacement, and consequent rupture with their symbolic construction space. In view of the growth horizon of the electricity sector in the country, this study sought to analyze how the negotiation process of the symbolic losses suffered by affected people has been conducted. The data were obtained from the analysis of documents followed by conducting interviews with those impacted by Estreito Power Plant, located in the middle Tocantins River between the States of Maranhão and Tocantins. This research highlighted the need to seek mechanisms that behold the symbolic values of people affected by dams, prioritizing the continuity of life that does not prize the logic of the market, but by living with dignity

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear understanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5,6,7 vast areas of the tropics remain understudied.8,9,10,11 In the American tropics, Amazonia stands out as the world's most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepresented in biodiversity databases.13,14,15 To worsen this situation, human-induced modifications16,17 may eliminate pieces of the Amazon's biodiversity puzzle before we can use them to understand how ecological communities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple organism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region's vulnerability to environmental change. 15%–18% of the most neglected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lost
