UNPLANNED URBANISATION AND ENVIRONMENTAL DEGRADATION
Urbanization is an inevitable phenomenon for the country like Bangladesh. The push and pull
factors help to migrate people from rural area to urban area. As a result haphazard and
unplanned urbanization create environmental degradation. Survey data reveals that inadequate
solid waste disposal services, lack of adequate public water supply, traffic congestion, water
logging, air pollution, noise pollution, hill cutting are the main problems in the city area.
Concentration of dust as well as SOx, NOx exceeded the allowable limit at the selected
points. Groundwater level of Sylhet city has a considerable lowering over the last few
decades. It has lowered from 3380 mm below ground in 1982 to 7880 mm below ground.
Sylhet is located in highly seismic risk zone but most of the buildings and other structures in
this area are constructed without considering earthquake risk. Environmental degradation
index was calculated based on economic condition of the country.
