[show abstract][hide abstract] ABSTRACT: Indiscriminate cutting of hills in the Sylhet region has become a major environmental issue. The nature and life style of Sylhet intimately related with the hills are thus under the threat of a drastic imbalance in its ecosystem. Due to such hill cutting the mostly affected sectors of this region will be its weather and climate, geomorphology and hydrology, and the indigenous flora and fauna. As a result the frequency of natural calamities like earthquake, flash flooding etc may increase considerably. Deforestation and resulting increased soil erosion, decreased ground water recharge and deteriorated water quality might also be as consequences of such hill cutting. This paper investigates the cause and extent of the problem along with its probable impact and finally suggests actions for conservation of hills for ecological balance of the region.

Currently a gigantic volume of solid waste is generated every day in the district towns of Bangladesh and unfortunately solid waste management is being deteriorated day by day due to the limited resources to handle the increasing rate of generated waste. In order to check the waste management situation, a detailed survey in different cities of Bangladesh has been done in this study. Although a significant amount of municipal waste is collected by community based organizations, conservancy wings of the cities can not dispose more than 50% of the generated wastes. This study reflects the adverse impacts of pollution through solid waste and deteriorating situation of municipal solid waste management in capital city Dhaka, divisional city Sylhet, greater district town Tangail and Rangamati and new district town Gazipur.
