- Due to the dynamic inter-relationship between human society and water resources, decision-making is a tricky task in water management sectors. In this study, multi-criteria analysis has been used as a decision support tool for the selection of a sustainable option in a regional channel improvement in Bangladesh. The Malnichara channel flows across the north-eastern divisional city of the country, and is responsible for storm water conveyance to the downstream Surma River. The channel was observed to be at risk due to anthropogenic activities such as encroachment, sewage and solid waste disposal and the filling up of natural depression basins. Using the multi-criteria analysis, three alternatives for channel improvement (sodding natural channel, lined natural channel and concrete box culvert) were evaluated with respect to ten indicators, grouped into four sustainability criteria (technical, economic, environmental and social). Sodding natural channel was found to be the optimal alternative, though the selection was sensitive to social criteria. Such a straightforward tool can efficiently be used to ensure sustainability of the channel through stakeholders' involvement in decision-making.

Comparative study of municipal solid waste treatment technologies using life cycle assessment method
- 2010

In: International Journal of Environmental Science and Technology. - 1735-1472. ; 7:2, s. 225-234

Journal article (peer-reviewed)abstract
- The aim of the study is to analyze three different waste treatment technologies by life cycle assessment tool. Sanitary Landfill, Incineration and gasification-pyrolysis of the waste treatment technologies are studied in SimaPro software based on input-output materials flow. SimaPro software has been applied for analyzing environmental burden by different impact categories. All technologies are favorable to abiotic and ozone layer depletion due to energy recovery from the waste treatment facilities. Sanitary landfill has the significantly lower environmental impact among other thermal treatment while gases are used for fuel with control emission environment. However, sanitary landfill has significant impact on photochemical oxidation, global warming and acidification. Among thermal technology, pyrolysis-gasification is comparatively more favorable to environment than incineration in global warming, acidification, eutrophication and eco-toxicity categories. Landfill with energy recovery facilities is environmentally favorable. However, due to large land requirement, difficult emission control system and long time span, restriction on land filling is applying more in the developed countries. Pyrolysis-gasification is more environmental friendly technology than incineration due to higher energy recovery efficiency. Life cycle assessment is an effective tool to analyze waste treatment technology based on environmental performances.

Green marketing or green wash? : A comparative study of consumers' behavior on selected Eco and Fair trade labeling in Sweden
- 2010
-
In: Journal of Ecology and the Natural Environment. - : Academic Journals. - 2006-9847. ; 2:6, s. 104-111
-
Journal article (peer-reviewed)abstract
- Green marketing is in the focus of present marketing strategy due to the pressure that comes from inclined environmental awareness in the global climate change. Different initiatives have been considered to support environmental programme and practices and one of the meaningful business initiatives is eco or fair trade labeling. Eco-label provides the information of product contribution in the context of environmental burden to the consumers. Different label initiatives are available in the present business market as a provider of ‘white goods’, however, the basic principles of the label initiative are ignored in most of the business practices. The study compared eight selected eco-brands which were used on the Swedish market. Comparison was based on environmental justice and ecosystem services perspectives. The study showed that most of the eco brands do not comply with environmental justice and ecosystem services in their label policy initiatives. Moreover, there is a gap between policy and practices. Questionnaire survey showed that environment is an important criterion for consumers while purchasing consumer products. Eco-label is an important tool; however, this tool is not communicating to consumers to its expected role.
