During 1987-89, Forestry was a department of the Ministry of Agriculture, under a Secretary. The Department of Environment (DoE) was established in Bangladesh in 1977 under the Environmental Pollution Control Ordinance, 1977. Finally, the Bangladesh Ministry of Forest and Environment was established in 1989.
Waste management in Bangladesh faces many challenges due to its large, rapidly growing population in a densely populated country. Bangladesh is the ninth most populous and twelfth most densely populated country in the world. In particular, the projected urban population growth rate from 2010 to 2015 is 3%. [1]
Bangladesh Environment Conservation Act (BECA) is set of laws enacted by the government of Bangladesh in 1995 to conserve the nation's environment. [1] Its main goals were to "provide for conservation of the environment, improvement of environmental standards and control and mitigation of environmental pollution."(Bangladesh Environmental Conservation Act, 1995).
Ex situ management can occur within or outside a species' natural geographic range. Individuals maintained ex situ exist outside an ecological niche. This means that they are not under the same selection pressures as wild populations, and they may undergo artificial selection if maintained ex situ for multiple generations. [3]
In 1977 the Environment Pollution Control Cell was created with 26 members. In 1989 the Government of Bangladesh created the Department of Environment from the Environment Pollution Control Cell and the Department of Public Health Engineering. [1] The department regulates pollution and can fine polluting industries. [5]
Air pollution is one of the most pressing environmental issues in Bangladesh, with the country frequently ranking among the most polluted in the world. [3] According to the World Air Quality Report, Bangladesh was the country with the worst air quality in 2020, a situation that has persisted over several years. [4]
In-situ conservation of seed-producing plant species is another conservation strategy. In-situ conservation involves the creation of National Parks, National Forests, and National Wildlife Refuges as a way of preserving the natural habitat of the targeted seed-producing organisms. In-situ conservation of agricultural resources is performed on-farm.
Bioremediation techniques can be classified as (i) in situ techniques, which treat polluted sites directly, vs (ii) ex situ techniques which are applied to excavated materials. [8] In both these approaches, additional nutrients, vitamins, minerals, and pH buffers are added to enhance the growth and metabolism of the microorganisms.
