Environmental concern of university students in the federal education institute in rural Goiás, Brazil

In this research the adaptation and validation of the Environmental Concern Scale (ECS) for Brazilian Portuguese and the environmental concerns of students were described. After being translated with the assistance of an expert teacher in Spanish language, the ECS was administered to two samples: one of university students (N=153) from Federal Institute of Education Goiano (IF GOIANO), Rio Verde campus, and another of public servants evaluators (N=13) from Federal Institute of Education, Science and Technology of Rondonia (IFRO), Colorado do Oeste campus. Content validity, reliability and construct validity were evaluated. Statistical properties obtained proved the quality of the measurement instrument of Environmental Concern. The agreement style of evaluators with the ECS admitted values for average central tendency, median and mode close to 4.00, in a scale of values from 1.00 to 5.00. The environmental concern of students was low.

Environmental performance of aquaculture in Rondônia state, Brazil

The objective of this study was to analyze the environmental performance of aquaculture in the city of Colorado do Oeste, Rondonia 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. Aquaculture in the city of Colorado do Oeste, Rondonia presents two fish production systems: extensive and semi-intensive. In the semi-intensive system, stocking rate was one fish per m 3 , 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 or ganic 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).

Análise da gestão ambiental nos Institutos Federais de Educação, Ciência e Tecnologia

The main objective was to analysis the environmental profile of the Federal Institutes of Education, Science and Technology (IF), when analyzing the environmental management practices. To achieve this goal was developed through an interview questionnaire which was answered by 230 Campuses in Brazil, in order to diagnose environmental management practices in this sector. Based on the assessment of the degree of implantation of certain aspects and environmental management practices was traced the environmental profile of the IF. The environmental management practices are the means by which organizations can improve their performance. An eco-efficient use of resources prevents waste generation and enables significant savings. An adequate environmental performance avoids costs resulting from the application of the polluter-pays principle. This work provided a baseline to support several of IF Campus, suggesting the advantages of using environmental management practices in order to improve environmental performance in these public educational, research and extension institutions. It was concluded that there is no environmental management in the Federal Institutes of Education, Science and Technology that meets the requirements of sustainability and that the Environmental Evaluation Index of the Federal Institutes of Education, Science and Technology (IADAIFE) for four Campi was very weak and for 78 Campi was weak.
