• Bangladesh
has
been
classified

• Following the guide lines of Framework for
development of Environment Statistics (UN-FDES)
Bangladesh Bureau of Statistics (BBS) developed BFDES in 1998.
• Following the guide line BBS has prepared
“Compendium of Environment Statistics 2009”.
• Data are collected from the secondary sources.
• MoeF has identified 5 areas of environmental issuesBiodiversity loss, Air pollution, Water pollution, Land
degradation and Natural disaster

Policy Adopted in Bangladesh
• Water Pollution control Ordinance 1973 (promulgated
in 1974).
• Bangladesh wild life (preservation) order 1973
(promulgated in 1974) & wild life (preservation) Act
1973

Biodiversity
• Bangladesh has about 5000 species of
flowering plants and 1500 species of fauna. It
was much more a century ago.
• Bio-diversity is effected:
- Deforestation
- Inefficient forest management
- Agricultural and industrial pollution
5
Biodiversity (Continued)
-
Shifting cultivation in the tribal areas
Coastal shrimp farming
Large scale irrigation
And flood control projects in Bangladesh

Flora
• It is recorded 7095 (apx) species of different plant
(MOef 2007).
• Total forest area less than 17%, day by day it is
reduce due to increasing of population and
landlessness.
• According to latest account about 96 seed-bearing
plant species are threatened.
• According to task force report 9 vascular plants are
endangered and 27 are threatened
• Government has taken some steps for afforestation
7
Fauna
• The total number of animal species of Bangladesh 4469.
• Vertebrate fauna of Bangladesh is 1597.
• According to IUCN Red Book 266 species of inland fishes,
442 species of marine fishes, 22 species of amphibians, 109
inland reptiles,17 marine reptiles, 388 resident birds, 240
migratory birds, 110 inland mammals and 3 species of marine
mammals exist in Bangladesh.

threatened.
• Number of extinct fauna of Bangladesh is 17.
• Number of marine species are 1093.

Atmosphere
• Tropical monsoon climate (high temperaturehigh humidity, heavy rainfall). Mean annual
temperature of Bangladesh is 26oc. Average
rainfall 1300 mm. to 4000 mm.
• Increasing trend of temperature.
• Decreasing trend of Monsoon.
• Recently, Seasons are not behaving regular.
9
Air Pollution
• Atmospheric conditions both urban and rural areas are
deteriorating due to air pollution.
• Uncontrolled emission from motor vehicles, dust, industrial
waste product, construction dust, garbage, brick kilns, cooking
stoves, burning of wood, coal and bio-mass are mainly
responsible.
• Common pollutants: Dust, Carbon monoxide, Nitrogen oxide
& Sulpher dioxide, Respirable suspended particulates (RSP),
Smoke etc.
• Effects on human health such as cronic chronic bronchitis,
acute respiratory infection in children, lung cancer, Stroke &
Heart diseases, abnormality during birth.
10
Sound Pollution
• Main sources of sound pollution are the
hydraulic horn of vehicles, aircraft, railroads,
industry, construction, Miking, brick breaking,
sirens and consumer products.
• Noise levels in selected area Dhaka city varies
from 68 dB to 106 dB (Dey, 2001).
• Government is trying to reduce sound
pollution in capital dhaka.
11
Water and Soil Pollution
• Bangladesh receives water: 74% from transboundary,
24% from rainfall & 2% from groundwater.
• Source of pollution: Industrial effluent (textiles,
tanneries, pulp and paper mill, fertilizer), municipal
waste, chemical fertilizer & pesticide, oil & lube
spillage from sea & river ports.
• Arsenic contamination in the groundwater (57 million
people in Bangladesh drink water containing arsenic).
9136 death per year due to arsenic related diseases.
• Increasing salinity in the coastal regions during dry
seasons.
12
Solid Waste Management and climate change
• Approximately 16,380 tons/day of waste are
generated in urban areas .
• Dhaka city corporation has established a Solid Waste
Management cell.
• Due to climate change floods, tornados, cyclones
(sidr, aila), drought and salinity ingress.
• If 1 meter rise of Sea level will inundate 17% of the
country and GDP effect will be 7%.
• Last 10 years 3 big floods has occurred in
Bangladesh (1998, 2004 & 2007).

Millennium Development Goal-7:
Bangladesh Progress at a Glance
• Bangladesh Government try to achieve the goal in the
area:
• Forest area – 9 (Base year 1990-95) to 11.3 (2006),
where target is 20 in 2015
• Biological diversity -1.6 (Base year 1990-95) to 1.83
(2006) where target is 5 in 2015
• Carbon Dioxide Emissions – .14 (Base year 1990-95)
to .3 (2006)
• Consumption of Ozone depleting CFCs – 280.6 (Base
year 1990-95) to 195.5 (2006)
