Conduziu-se este trabalho, com o objetivo central de analisar o perfil ambiental dos Institutos Federais de Educação, Ciência e Tecnologia (IF), quando analisadas as práticas de gestão ambiental. Para atingir esse objetivo foi desenvolvida uma entrevista por intermédio de questionário, o qual foi respondido por 82 Campi do Brasil, de um total de 230, de forma a poder diagnosticar práticas de gestão ambiental nesse setor. Com base na avaliação do grau de implantação de determinadas vertentes e práticas de gestão ambiental, foi traçado o perfil ambiental dos IF. As práticas de gestão ambiental são meios pelos quais as organizações podem melhorar o seu desempenho. Um comportamento ecoeficiente otimiza o uso dos recursos e evita a produção de resíduos, permitindo poupanças significativas. Um bom desempenho ambiental evita custos resultantes da aplicação do princípio do poluidor-pagador. Este trabalho constituiu uma base de apoio aos diversos Campi dos IF, sugerindo quais as vantagens de recorrer a práticas de gestão ambiental, de forma a aumentar o desempenho ambiental nessas instituições de ensino, pesquisa e extensão públicas. Concluiu-se que não há gestão ambiental nos Institutos Federais de Educação, Ciência e Tecnologia que preencha os requisitos da sustentabilidade e que o Índice de Avaliação Ambiental dos Institutos Federais de Educação, Ciência e Tecnologia (IADAIFE) para quatro Campi foi muito fraco e para 78 Campi foi fraco.

The objective of this study was to analyze the environmental performance of aquaculture in the city of Colorado do Oeste, Rondônia State, Brazil. Fifteen fish farmers were interviewed. For data collection, structured interviews were carried out, using a questionnaire based on information supplied by the United Nations Food and Agriculture Organization (FAO). The questionnaire considered 12 items, organized into three main topics: a) social and legal standards b) environmental standards c) standards of food safety and hygiene. The questionnaire considered 12 items, organized into three main topics: a) social and legal standards b) environmental standards c) standards of food safety and hygiene. Aquaculture in the city of Colorado do Oeste, Rondônia presents two fish production systems: extensive and semi-intensive. In the semi-intensive system, stocking rate was one fish per m3, on average; tambaqui (Colossoma macropomum), tilapias (Oreochromis spp.), pirarucu (Arapaima gigas) and pintado (Pseudoplatystoma spp.) were the species farmed at the largest number. The rate of water renewal was due to the greater availability of natural food in this system. Water renewal was constant in the ponds (1,500 liters per minute). In the semi-intensive system using dug ponds, alevins were stocked and fed during the entire rearing time with natural and exogenous food. The extensive system relied on the natural production of the pond, with stocking density limited by the production of natural food. The little renewal of water made the cultivation tank itself acted as a decantation lake, with the occurrence of oxidation and sedimentation of residual organic matter, consisting of feces, debris and organic fertilizer. Production of reduced effluent volume took place in the extensive system, compared to the cultivation area. In addition, there was high water turbidity, caused by high concentration of planktonic organisms, and low concentrations of dissolved oxygen in the water. Data showed that nine estates of the interviewed fish farmers had critical environmental performance (less than 30.0%). Six estates of fish farmers had bad environmental performance (between 30.0 and 50.0%) (Coefficient of sustentainability = green square x 100 ÷ Total Questions less the yellow squares)

This study aimed to evaluate social and environmental aspects of family farming at Cacoal City, Rondonia State, in Brazil. This is applied in non-experimental (descriptive) research. Questionnaire was designed as the main tool of the study. Eleven (11) semi-structured interviews were conducted with family farmers from eleven cooperative associations. Quantitative and qualitative approaches were employed in the scientific research, using a questionnaire consisting of twenty four questions that sought to evaluate environmental aspects of the sample of family farmers. It was concluded that agriculture continues to be basis of the local development and rurality model found in the Western Amazon Brazil.
