Changing the Status Quo in Environmental Engineering Education in Response to Emerging Markets

The job market and skill needs have been expanding for environmental engineers requiring more interdisciplinary training and global citizenship. The 1970s was a decade of regulatory activities, the 1980s was a decade of major environmental disasters, the 1990s was a decade for global awakening, and the first decade of the 21st century is becoming the decade of concern for increasing global environmental stress. In parallel with the environmental trends, the environmental engineering programs have evolved from strictly water/wastewater focus to interdisciplinary programs with a wide selection of courses such as computer science, meteorology, aquatic biology, and ecology in addition to the classical environmental engineering curriculum. Advancements in science and technology, changing demographics, new delivery structures, changes in educational programs and policies, new regulatory requirements, increased global interactions, and recent large scale events with significant environmental impacts have increased the needs for engineers who are trained in environmental engineering discipline with adequate skills for addressing the emerging challenges. This technical note presents the emerging job markets and the corresponding skill needs for environmental engineers to respond to current and evolving environmental challenges both at regional and global scales.     

The impact of behavioural difficulty on the saliency of the association between self-determined motivation and environmental behaviours.

Evaluated the impact of the perceived level of difficulty of environmental behaviours on the magnitude of the relationship between environmental self-determination and the occurrence of environmental behaviours. 444 undergraduates (aged 17–50 yrs) completed the Motivation Toward the Environment Scale (L. G. Pelletier et al, in press), along with self-report measures of environmental behaviours and perceived difficulty of environmental behaviours. Three types of environmental behaviours were examined: recycling, purchasing environmentally-friendly products, and educating oneself as to what can be done for the environment. It was hypothesized that the level of self-determination of environmental motivation significantly predicts the occurrence of environmental behaviours. Data were subjected to structural equation modeling analyzes. Results support the proposed hypothesis. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Environmental Impact of Solid Waste Treatment Methods in Korea

The environmental impact of various solid waste treatment methods being used in Korea was assessed to provide useful information for decision making in solid waste management strategy. Among the treatment methods considered, the incineration method and the anaerobic digestion method are the most environmentally friendly, while the landfill method has the highest environmental impact. Regarding the life cycle of the treatment methods, the environmental impact of the main treatment stage is the largest, contributing 46–94% of the total impact, depending on the treatment method. The environmental impact due to wastewater treatment was 6.2, 0.2, 4.1, and 9.0% for landfilling, incineration, composting, and anaerobic digestion, respectively. Among the environmental impact categories considered, global warming, eutrophication, and acidification are the key contributors to environmental impact, with a range of 53 to 91% of the total environmental impact depending on the selected treatment method. Of these key contributors, global warming has the largest contribution. Other contributors to environmental impact, such as photochemical oxidant creation, abiotic resource depletion, and ozone depletion, contribute little to the total environmental impact. These results make it possible to construct an environmental data set and examine the environmental impact of the life cycle of various waste treatment methods to support decision making in solid waste management strategy.

Adolescents' motivation toward the environment: Age-related trends and correlates.

From a self-determination perspective, we attempted to replicate previous findings suggesting that higher autonomous environmental motivation (i.e., acting out of choice and pleasure) is associated with the frequency of environmental behaviours such as recycling, paper reuse, and energy conservation. We also compared students' level of autonomous environmental motivation with their level of autonomous academic motivation. We then examined age effects on autonomous environmental motivation and compared them to age effects on autonomous academic motivation. A total of 200 high school students grouped into 5 age cohorts filled out a questionnaire. Results showed that (1) adolescents' autonomous environmental motivation was associated with more frequent environmental behaviours, (2) autonomous motivation was higher in the environmental than the school domain, and (3) autonomous environmental motivation was higher in older than younger students, whereas autonomous motivation toward school was equivalent across age groups.
