It has a population of about 128million. It has a boundary line on the West. north and east with India and the sou’-east with Myanmar. The whole state consists of chiefly low and level land except for the hilly parts in the nor’-east and sou’-east. Physiographical the state can split into hills. uplifted land blocks. and the bulk alluvial fields. The Environment of Bangladesh is diverse and mix of traditional and modern methods of land usage.

Environmental Resources:

The primary beginnings of environmental resources in the state can be considered to be the bing natural and human resources. Bangladesh this is really low compared to the denseness of population. and their demands. The environmental resources of the state have been summarized into two major parts. That is:

1. Natural Physical resources
2. Natural Biotic resources

Now I describe the major environmental resources.

Natural Physical resources:

Natural physical resources are divided into many parts. All the parts the most of import parts which reflect the quality of ambiance of Bangladesh is given below:


The land of Bangladesh can be grouped into three major units’ hill dirts. old alluvial dirts and recent alluvial dirts. The hill soils means the Himalayan ranges. Chittagong hills and knolls of sylhet. Old alluvial dirts are seen in the Madhupur and Barind. The dirts of these have been formed on the old alluvial sediment of the Pleistocene era. Recently old alluvial sediments are found in the Gangas alluvial sediment. Teesta silt and Brahmaputra alluvial sediment.

Water System:

Bangladesh is the largest delta in the universe formed in the universe by the Gangas. the Brahmaputra. and the Meghna river system. The delta is characterized by level with the intricate system of rivers and tidal channels. Three major rivers have a immense catchment country of 1. 554. 000 sq kilometer. distributing over five states. There are 700 rivers. cannels and watercourses in Bangladesh. The chief river system busying the delta formed by the Gangas and the Brahmaputro which one time they entry Bangladesh are known as the Padma and the Jamuna. The Jamuna joins the Padma near Aricha and flows up to chandpur where it joins The Meghna and the combined flow is the Meghna. The river fluxing from the hills situated in the sou’-east of Bangladesh. viz. Karnaphuli. Sangu. Matamuhuri and Knaaf flow into the Bay of Bengal. The of import river in this part is the Karnaphuli which is besides the longest. 274 kilometer.

Climate of Bangladesh:

The hot summer seasons from March to June is characterized by high temperatures in a hebdomad or more yearss are the highest rate of vaporization. and fickle but heavy rainfall.

From June to October is the hot and humid monsoon season with temperatures runing and heavy rainfall and two-third of the average one-year rainfall.

The ice chest and drier winter extends from November to March. When temperatures range from 8C to 15C and minimal temperatures can fall below 5C in the North. The temperatures fall throughout November to December. and in the last hebdomad of December.

Natural Biotic Resources:

Terrestrial and aquatic ecological resources play an of import function in state development. They serve as rich beginnings of nutrient and fuel for the population. Forest provides a broad scope of home ground of wildlife. and the wetland ecosystem provides home ground for aquatic species.

Tellurian Ecology:

Forests are both environmentally and economically of import natural resources in the tellurian ecology. The entire land under wood in Bangladesh is about 2. 56 million. which includes officially classified and unclassified province lands. Although a important portion of bing forest country. In Bangladesh natural forest country is 31 % and forest plantation is 13 % . The wood of Bangladesh has been cut downing at an speed uping rate. The major causes of deforestation are industrialisation. rapid urbanisation. and high population growing. both for colony and switching cultivation. In recent twelvemonth and estimated figure of 109. 92 million in the urban country and plantation along roads main roads and railroads.

Aquatic ecology:

For the intent of Ramsar convention wetland are defined as country of fen. fen. peat land or H2O. Wetlands are priceless constituents of the environment in Bangladesh. The entire country of wetlands in the state has been estimated at seven to eight million Hectors or 50 % of the entire land surface. The wetlands of Bangladesh are progressively being recognized as home ground and flight screen for a big assortment of wildlife. The alimentary merchandises of wetlands in Bangladesh are carried by rivers and floodwater. and the systems downstream. The wetlands of Bangladesh are being drastically affected by the impact of the burgeoning human population. Approximately 2. 1 million wetland have been lost of inundation control. drainage and irrigation development. Wetlands are being continuously lost because of assorted recent developments such as shrimp civilization. which reflect a deficiency of community consciousness of wetland map.

Major Environmental Problems:

The procedure through which fresh ( potable ) H2O becomes salt ( undrinkable ) H2O ; hence. desalinization is the rearward procedure ; besides involves the accretion of salts in surface soil caused by vaporization of inordinate irrigation H2O. a procedure that can finally render dirt incapable of back uping harvests.


Occurs when H2O channels and reservoirs become clogged with silt and clay. a side consequence of deforestation and dirt eroding.

Slash-and-burn agribusiness:

A revolving cultivation technique in which trees are cut down and burned in order to clear land for impermanent agribusiness ; the land is used until its productiveness diminutions at which point a new secret plan is selected and the procedure repeats ; this pattern is sustainable while population degrees are low and clip is permitted for regrowth of natural flora ; conversely. where these conditions do non be. the pattern can hold black effects for the environment.

Soil eroding:

The remotion of dirt by the action of H2O or air current. compounded by hapless agricultural patterns. deforestation. overgrazing. and desertification.


A works or carnal species whose presence. copiousness. and wellness reveal the general status of its home ground.

Salvage the Environment:
