Relandfill activity, which means digging up landfill waste and recovering resources, can remove the material having been landfilled, and will free up the land to be reused as new landfill space. We have extended the WIO model for environmental assessment including re-landfill activity. As a part of this work, we have estimated landfill consumption and CO2 emission based on 4 kinds of scenarios ...

The development efforts of successive governments during the last several decades have led to growth in per capita incomes, increase in standard of living of the people and decrease in overall poverty levels.

In the present study, land use/land cover changes has been evaluated in the decade between 1989 and 2010 utilizing Landsat TM5 satellite images in the Hugli estuary which stretches across 4817.98 km 2 of Gangetic delta in West Bengal, India, predominantly dominated by mangrove plantation. The study utilizes supervised classification techniques using Fuzzy Cmean classification algorithm. The mai...

Environmental management research on the hotel industry has touched little upon the topic of environmental performance assessment. This study uses ecological footprint models to assess natural resource consumption in the hotel industry and the burden it puts on the environment. Findings of the study indicated that: (1) As the star rating goes up, hotels tend to consume greater amounts of resour...
