Impact of Environmental Issues in Construction Sector: Bangladesh Perspective

The common features of most of the Asian cities are high density of population, scarcity of land, unplanned growth and expansion of cities and overall environmental and ecological degradation. Some of the developing countries of Asian have already been alarmed by the present situation and to avoid the future disaster the impact of environmental issues needed to be prioritized. Bangladesh faces the constant challenges of rampant poverty, high population density, and increasing population rate. Poor people are arsenic contaminated and urban people are mostly exposed to the polluted air, recurring natural disasters and a dwindling natural resource base. It is one of the poorest countries of the developing world, with a low resource base, a very low land-man ratio, and is threatened by both natural hazards and overexploitation. However this resource base is under see threat and environmental planning is necessary to signal any hope for survival with dignity and sustainability. Therefore, Bangladeshi peoples need awareness, protection and national environmental policy. With this objective, the Government of Bangladesh had established several Commissions and Committees since the independence of the country. So it is necessary to consider that a well-arranged framework for a global analysis is important in respect of environmental impact in construction sector to current situation. Environmental impact and construction engineering is the most discussed subject in the present time. It becomes the central issue not only for Bangladesh context as well as in the international debate in the early part of twenty first century. The land, water, air, sea, ocean, hill, mountain, roads, transport, industry and its sound, human, animals, insects, trees etc. consisting of whole environment. The development & survival of human fully depend on the peaceful and balanced coexistence of the environment. But most regretfully, the human society is destroying the equilibrium of nature by changing and mishandling the mineral resources. As a result the human society is facing the natural disasters with certain intervals. Therefore it is essential to rethinking that a good-arranged structure for a historical study is significant in respect of environmental impact in construction.
