Environment and Biodiversity Basics :
· The average temperature of the earth is
16ÂșC.
· The most unique feature of the earth is
its buffering action due to which a neutral pH (pH7)is maintained in the soil
and water bodies.
· The diversity of living organisms is
comprised of five kingdoms of life. Monera,
Prototictista,Fungi, Plantae and
Animalia.
· The environment may be defined as the
surroundings or conditions in which an organism lives or operates.
· The human beings (Homo sapiens sapiens),
evolved more than two million years ago.
· Petroleum is also called mineral oil.
Like petroleum, natural gas is a mixture of gaseous hydrocarbons
· The earliest human ancestors, the
Australopithecines which walked upright, evolved around 3.5 million years ago
in South Africa.
· Remains of Neanderthals have been found
in Europe, Asia and Africa.
· At certain depth of the soil, all the
pore spaces between soil particles are saturated with water. This depth is
called Water table
· Earth has four major habitats-(1)
Terrestrial (2) Freshwater (3) Estuarine (Where rivers meet the ocean) and (4)
Ocean
· The term niche means the sum of all the
activities and relationships of a species by which it uses the resources in its
habitat for its survival and reproduction.
· An adaptation is thus, “the appearance
or behaviour or structure or mode of life of an organism that allows it to
survive in a particular environment”.
· Speciation is the process by which new
species are formed and evolution is the mechanism by which speciation is
brought about.
· Two basic forms of population growth
curves can be identified. (i) ‘J’ shaped growth curve and the (ii) ‘S’ shaped
or sigmoid growth curve.
· Succession that occurs on land where
moisture content is low for e.g. on bare rock is known as xerarch. Succession that takes place in a water body, like
ponds or lake is called hydrarch.
· The interaction that occurs among
different individuals of the same species is called intraspecific interaction
while the interaction among individuals of different species in a community is
termed as interspecific interaction.
· Standing crop biomass is the amount of
the living matter at any given time. It is expressed as gm/unit area or kilo
cal/unit area
· Jajmani system: Each village is grouped
into (i) jajmans and (ii) service provider castes who are paid in cash or kind.
Jajmans are land owners. They come from upper castes while service provider
castes are at a middle or lower level.
· Timber accounts for 25% of all
photosynthetic materials produced on the earth and about half of the total
biomass produced by a forest.
· Asprin, which is probably the world’s
most widely used drug was developed according to a chemical “blueprint”, from a
compound extracted from the leaves of tropical willow trees.
· In 1950 the Government of India began
the annual festival of tree planting called the Vanamahotsava. Gujarat
was the first state to implement it.
· Tehri
power project which is a 260.5m high earth and rock fill dam near
the Tehri town in Garhwal Himalayas.
The project site is situated a little downstream the junction of Bhagirathi and Bhilganga rivers
· The Great Indian Bustard (Ardeotis nigriceps ) is an example of rare species of India.
·
India has nearly 45,000 species of
plants and 75,000 species of animals.
· Tetraethyl lead (TEL) is used as an
anti-knock agent in petrol for smooth and easy running of vehicles.
· Under the “Montreal Protocol” amended in 1990 it was decided to completely phase out CFCs to prevent damage of ozone
layer.
·
Noise
level is measured in terms of decibels (dB). W.H.O. (World Health Organization)
has prescribed optimum noise level as 45 dB by day and 35 dB by night. Anything
above 80 dB is hazardous.
· Pollution of water bodies by mercury
causes Minamata disease in humans and dropsy in fishes. Lead causes displexia,
cadmium poisoning causes Itai – Itai disease etc.
· ‘Eu’ maens well or healthy and ‘trophy’
means nutrition. The enrichment of water bodies with nutrients causes
entrophication of the water body.
· The sudden and explosive growth of
phytoplankton and algae impart green colour to the water is known as water
bloom, or “algal blooms”. These phytoplankton release toxic substances in water
that causes sudden death of large population of fishes. This phenomenon of
nutrient enrichment of a water body is called eutrophication.
· The sewage water can be treated to make
it safe for disposal into water bodies like rivers, lakes etc. Thetreatment
involves three stages: primary, secondary and tertiary. This includes
1.sedimentation, 2. coagulation/flocculation, 3.filtration, 4.disinfection,
5.softening and 6.aeration. The first four steps are of primary treatment. The
first three steps are involved in primary treatment remove suspended
particulate matter. Secondary treatment removes organic solids, left out after
primary treatment, through their microbial decomposition. Effluents after
secondary treatment may be clean but contain large amounts of nitrogen, in form
of ammonia, nitrates and phosphorous which can cause problem of eutrophication upon
their discharge into a receiving water body such as river, lake or pond. The
tertiary treatment is meant to remove nutrients, disinfect for removing
pathogenic bacteria, and aeration removes hydrogen sulphide and reduce the
amount of carbon dioxide and make water healthy and fit for aquatic organisms.
This treatment of waste water or sewage is carried out in effluent treatment
plants especially built for this purpose. The residue obtained from primary
treatment one known as sludge.
·
The worse case of nuclear pollution was
the cherndoyl disaster in Russia occured in 1986 but the effects still longer
today.
· Radiation
damage can be divided into two types: (a) somatic damage (also called radiation
sickness) and (b) genetic damage. Somatic damage refers to damage
to cells that are not associated with reproduction. Effects of somatic
radiation damage include reddening of the skin, loss of hair, ulceration,
fibrosis of the lungs, the formation of holes in tissue, a reduction of white
blood cells, and the induction of cataract in the eyes. This damage can also
result in cancer and death. Genetic damage refers to damage to cells associated
with reproduction.
This damage can subsequently cause genetic damage from gene mutation resulting
in abnormalities. Genetic damages are passed on to next generation.
· A traditional unit of human-equivalent
dose is the rem, which stands for radiation equivalent in man. At low doses,
such as what we receive every day from background radiation (< 1 m rem), the
cells repair the damage rapidly. At higher doses (up to 100 rem), the cells
might not be able to repair the damage, and the cells may either be changed
permanently or die. Cells changed permanently may go on to produce abnormal
cells when they divide and may become cancerous.
·
Atmosphere of asbestos mines contains
asbestos dust which causes asbestosis, silica
causes
silicosis,
·
Leukemia and lymphoma are cancers which
are initiated in blood-forming cells. Most
cancers
are named after the organ concerned e.g. Cancer that begins in lungs is lung
cancer
and the one in skin is known as melanoma. The cancer-causing agents are known
as
carcinogens. Agents present in the environment are the environmental
carcinogens.
· Excessive use of pesticides
particularly
herbicides like 2,4dichlorophenoxyacetic
acid
(2,4-D) has been
associated
with a 200-800% increase of NHL (Non-Hodgkin’s Lymphoma) – one
type
of cancer in Sweden. Pesticides such as toxaphene, hexachlorocyclohexane
(BHC),
trichlorophenol, dieldrin, DDT are known to cause lymphatic cancer in rats and
mice.
· Once the level of nitrates in soil
exceeds 10 ppm it may become harmful. In areas where ground water is the only
source of drinking water, this causes methaemoglobinaemia
particularly in bottle fed infants who are very sensitive to this
pollutant.
· Methaemoglobin is formed when iron in
the haemoglobin molecule is oxidized from Fe2 + (ferrous) to Fe 3 + (ferric)
form. Due to reduced carrying capacity for oxygen the babies
gradually
acquire a blue tinge and hence the name
– “Blue Baby disease”. Symptoms
are sleeping,
poor feeding, decreased energy, etc. Nitrates can be removed from the
water
by processes like electrodialysis and reverse osmosis. Nitrites in the water
can be
oxidized
to nitrates by introducing a strong oxidant like ozone in the water.``

·
In Japan,
mass mercury poisoning (Minamata disease) was observed in 1960s, caused by
eating fish from Minamata Bay which were
contaminated with methyl mercury
· Typical symptoms of mercury poisoning
are irritability, excitability, loss of memory, insomnia, tremor and gingivitis
· Itai-itai
disease first reported from Japan in 1965 was attributed to
cadmium contamination in water and rice caused by discharge of effluents from a
zinc smelter
into a river. The deposits of coal dust makes miners lungs look black instead
of a healthy pink and hence the name black
lung disease. Black lung disease is the common name for pneumoconiosis (CWP) or anthracosis,
· Dengue is also called Breakbone Fever,
or Dandy Fever . Dengue is caused by a virus transmitted through a mosquito
called Aedes aegypti or Asian tiger mosquito.
· Bovine spongiform encephalopathy (BSE or
mad cow disease) in cattle is caused by aninfectious agent that has a long
incubation period, between two and five years.
·
Mortality refers to the death of
individuals.
·
Natality is an expression of the
addition of new individuals in a population.
·
Water on earth is classified into
following three types:
(a) Fresh water:
It is inland water and its salt content is less than 5 ppt or 0.5%;
(b) Marine water: It occurs in seas, oceans and its salt content is more than 35 ppt or
3.5%.
(c) Brackish water: It’s salt content is more than 5 ppt but less than 35ppt. It is present in
estuaries, salt
marshes and salt lakes. A lot of underground water in Rajasthan, Gujarat,
Haryana and Punjab
is brackish.
·
The important global environmental
issues are:
•
green house effect and global warming
•
biodiversity loss
•
desertification
•
depletion of ozone layer
•
acid rain
•
oil spills
•
dumping of hazardous wastes
·
Ultra violet (UV) radiation, with
wavelengths shorter than visible spectrum has high
energy.
UV radiations can be divided into three forms: UV-A (wavelength between
320-400nm),
UV-B (wave length lesser than 280 nm), and UV-C (wavelength
lesser
than 280 nm). UV-C is most damaging to biological systems.
·
One chlorine atom can break down
1,00,000 ozone molecules.
·
Measures to prevent ozone (O3) layer
depletion Global awareness and action on the part of world community in the
form of Helsinki (1989), Montreal (1990’s) conventions and protocol have had
some important success on this front. A complete ban on the use of CFCs and
other ozone destroying chemicals is recommended. Further, use of HCFCs
(Hydrochloric fluorocarbons) as a substitute for CFCs is being recommended on
temporary basis because HCFCs are relatively less damaging to ozone layer as
compared to CFCs, but they are not completely ozone safe.
· Acid rain is caused by atmospheric
pollution from acidic gases such as sulphur dioxide and oxides of nitrogen
emitted from burning of fossil fuels. Acid rain damage cuticle of plant leaves
resulting etiolation of foliage. This in turn reduces
photosynthesis.
Reduced photosynthesis accompanied by leaf fall reduces plant and crop
productivity.
· Norman Myers, a British Ecologist,
developed the concept of hot spots in 1988 to designate priority areas for in
situ conservation. According to him, the hot spots are the richest and the most
threatened reservoirs of biodiversity on the earth.
The criteria for
determining a hot spot are:
(i) The area
should support >1500 endemic species,
(ii) It must have
lost over 70 % of the original habitat
Twenty-five
biodiversity hot spots have been identified in the world
Among the 25 hot
spots of the world, 2 are found in India namely western ghats and the eastern
Himalayas.
These two areas of the country are exceptionally rich in flowering plants, reptiles, amphibians,
butterflies and some species of mammals.
·
The trans-Himalayan region with its
sparse vegetation has the richest wild sheep and goat
community
in the world. The snow leopard (Panthera uncia) and Black-necked Crane
(Grus
nigricollis) are found here. The Great Indian Bustard (Ardeotis nigriceps)
which is highly endangered bird, is found in (Gujrat) region, rich in extensive
grasslands.
·
According
to the Red List by IUCN( International Union for the Conservation of Nature and
Natural Resources, IUCN)), in India, 44 plant species are critically
endangered.,113 endangered and 87 vulnerable. Amongst animals, 18 are
critically endangered, 54 endangered and 143 Vulnerable.
·
Conservation efforts can be grouped into
the following two categories:
1. In-situ (on-site) conservation includes
the protection of plants and animals within
their natural habitats or in protected
areas. Protected areas are land or sea dedicated to protect and maintain
biodiversity.
2. Ex-situ (off-site) conservation of
plants and animals outside their natural habitats.
These include botanical gardens, zoo,
gene banks, seek bank, tissue culture and
Cryopreservation
Some
of the main sanctuaries in India are:
The
Jim Corbett Tiger Reserve- Uttaranchal, Kanha National Park, Madhya Pradesh,
Bandhavgarh
National Park- Madhya Pradesh, Ranthambhor National Park-Sawai
Madhopur,
Gir National Park-Sasangir (Gujarat) etc.

deserts. In wesern Himalayas, one can see birds like Himalayan monal
pheasant, western tragopanm koklass, white crested khalij pheasant, griffon
vultures, lammergiers, choughs, ravens. In the Andaman and Nicobar region, about 250 species and subspecies of birds are
found, such as rare Narcondum horn bill, Nicobar pigeon and megapode. While
the national parks and sanctuaries in South India, too. For e.g. Madumalai in
Tamil Nadu and Bandipur Tiger Reserve and Nagahole National Park in Karnataka.

·
Thirteen biodiversity- rich
representative ecosystems , largely within the forest land ( total area –
53,000 sq. km. ),have been designated as Biosphere Reserves in India.
·
A Biosphere Reserve consists of core,
buffer and transition zones.
(a) The core zone is fully protected and
natural area of the Biosphere Reserve least
disturbed
by human activities. It is legally protected ecosystem in which entry is not
allowed except with permission for some special purpose. Destructive sampling
for scientific investigations is prohibited.
(b)
The buffer zone surrounds the core zone and is managed
to
accommodate a greater variety of resource use strategies, and research and
educational activities.
(c)
the transition zone, the outermost part of the Biosphere Reserve, is an area
of
active cooperation between the reserve management and the local people, wherein
activities
like settlements, cropping, forestry , recreation and other economic that are
in harmony with the conservation goals. Till date there were 553 biosphere
reserves located in 107 countries.
·
Crocodile
breeding and management project
This
project was started in 1976 with FAO - UNDP assistance to save three endangered
crocodilian species, namely, the fresh water crocodile, salt water crocodile
and the rare gharial. Eleven sanctuaries have been declared specially for
crocodile protection including the National
Chambal Sanctuary in Madhya Pradesh.
·
The Wildlife
Protection Act (1972) contain provisions for penalties or punishment
to
prevent poaching and illegal trade. India is also a signatory to the Convention
on
International
Trade in Endangered Species of Wild Fauna and Flora (CITES).
The
Convention entered into force on 1st July, 1975. In addition to this, India is
also a
signatory
to Convention on Biological Diversity
(CBD), which it signed on 29th
December, 1993
at Rio de Janeiro during the Earth Summit. The Convention has
three key
objectives:
1. Conservation
of biological diversity,
2 Sustainable
use of biodiversity and
3. Fair and
equitable sharing of benefits arising out of the utilization of genetic
resources.
·
Habitat protection is the main in-situ approach. The Protected
Area Network for
habitat
protection includes national parks,
wildlife sanctuaries, biosphere reserves,
sacred groves or
sacred forests.
•
Ex-situ
conservation is doen by setting up botanical gardens, zoos, gene banks and
seed
banks, cryopreservation and preservation of germplasm.
·
IUCN
and WWF are among the leading international organizations concerned
withbiodiversity conservation. The Wildlife Protection Act (1972) and
Biodiversity Act (2002) at the national level and The CITES and The Convention
on Biodiversity at the international level regulate the trade in biodiversity
and promote its conservation and sustainable use.
·
The
forty second amendment Clause (g) to Article 51A of the Indian constitution
made it a fundamental duty to protect and improve the natural environment.
·
There is a directive, given to the State
as one of the Directive Principles of State Policy(DPSP) regarding the protection and improvement of the environment.
Article 48A states “The State shall
endeavour to protect and improve the environment and to safeguard the forests
and wildlife of the country”.
·
The department of Environment was
established in India in 1980 to ensure a healthy
environment
for the country. This later became the Ministry of Environment and Forests in 1985.
This Ministry has overall responsibility for administering and enforcing
environmental
legislations
and policies.
·
The
Water (Prevention and Control of Pollution) Act of 1974 and
Amendment,
1988
The main objective of
this act is to provide prevention and control of water pollution and maintaining
or restoring of wholesomeness and purity of water
·
The
Water (Prevention and Control of Pollution) Cess Act of 1977
The Water Cess
Act
was passed to generate financial resources to meet expenses of the Central and
State Pollution Boards. The Act creates economic incentives for pollution control
and requires local authorities and certain designated industries to pay a cess
(tax) for water effluent discharge.
·
The
Air (Prevention and Control of Pollution) Act of 1981 and amendment,
1987
The
main objectives of this Act are to improve the quality of air and to prevent,
control and abate air pollution in the country
States not
having water pollution boards were required to set up air pollution boards.
•
Under the Air Act, all industries operating within designated air pollution
control areas must obtain a “consent” (permit) from the State Boards.
•
The states are required to prescribe emission standards for industry and
automobiles
after
consulting the central board and noting its ambient air quality standards.
•
Act granted power to the Board to ensure compliance with the Act including the
power
of entry for examination, testing of equipment and other purposes and power
to
take the sample for the purpose of analysis of air or emission from any
chimney, fly
ash
or dust or any other outlet in such a manner as may be prescribed.
Notably,
the 1987 amendment introduced a citizen’s suit provision into the Air Act and extended
the Act to include noise pollution.
·
The
Environment (Protection) Act of 1986
In
the wake of the Bhopal tragedy, the government of India enacted the Environment
(Protection)
Act of 1986 Section 3 (1) of the Act empowers the centre to “take all such
measures as it deems necessary or expedient for the purpose of protecting and
improving the quality of the environment and preventing, controlling and
abating environmental pollution”. Specifically, the Central Government is
authorized to set new national standards for the quality of the environment
(ambient standards) as well as standards for controlling emissions and effluent
discharges; to regulate industrial locations, to prescribe procedures for
managing hazardous substances; to establish safeguards preventing accidents, and
to collect and dismantle information regarding environmental pollution.
BIODIVERSITY RELATED ACTS
Ă The
Wild Life (Protection) Act of 1972 and Amendment, 1982
In
1972, Parliament enacted the Wild Life Act (Protection) Act. The Wild Life Act
provides for state wildlife advisory boards, regulations for hunting wild
animals and birds, establishment of sanctuaries and national parks, regulations
for trade in wild animals, animal products and trophies, and judicially imposed
penalties for violating the Act. Harming endangered species listed in Schedule
1 of the Act is prohibited throughout India. Hunting species, like those
requiring special protection (Schedule II), big game (Schedule III), and small
game (Schedule IV), is regulated through licensing. A few species classified as
vermin (Schedule V), may be hunted without restrictions. Wildlife wardens and
their staff administer the act.
Ă The
Forest (Conservation) Act of 1980
First
Forest Act was enacted in 1927. This is one of the many surviving colonial
legislations.
It
was enacted to consolidate the law related to forest, the transit of forest
produce and the duty livable on timber and other forest produce. Subsequently,
the Forest (Conservation) Act was promulgated in 1980 to make certain reforms
over the preceding Act of 1927.The
1927
Act deals with the four categories of the forests, namely reserved forests,
village
forests,
protected forests and private forests . Alarmed at India’s rapid deforestation
and resulting environmental degradation, Centre Government enacted the
Forest
(Conservation) Act in1980. Under the provisions of this Act, prior approval of
the Central Government is required for diversion of forestlands for non-forest
purposes. An Advisory Committee constituted under the Act advises the Centre on
these approvals.
Ă Biodiversity
Act 2000
The
main intent of this legislation is to protect India’s rich biodiversity and
associated
knowledge
against their use by foreign individuals and organizations without sharing the benefits
arising out of such use, and to check biopiracy. The Act provides for setting
up of a National Biodiversity Authority (NBA), State Biodiversity Boards (SBBs)
and Biodiversity Management Committees (BMCs) in local bodies. NBA and SBB are required
to consult BMCs in decisions relating to use of biological resources or related
knowledge within their jurisdiction and BMCs are to promote conservation,
sustainable use and documentation of biodiversity.
This
bill seeks to check biopiracy, protect biological diversity and local growers
through a three-tier structure of central and state boards and local
committees. These will regulate access to plant and animal genetic resources
and share the benefits. The proposed National Biodiversity Authority (NBA) will
deal with all cases of access by foreigners. Its approval will be required
before obtaining any intellectual property right on an invention based on a
biological resource from India, or on its traditional knowledge. It will oppose
such rights given in other countries. The NBA will enjoy the power of a civil
court. In addition, centre may issue directives to state if it feels a
naturally rich area is threatened by overuse, abuse or neglect.
Ă Wetland Convention (Ramsar Convention)
It
is an international convention came in force in 1975. The convention provides
the
framework
for international cooperation for the conservation and wise use of wetland
habitats.
The United Nations Educational, Scientific and Cultural Organisation (UNESCO) serves
as the Depositary for the Convention, and its secretariat, the Ramsar Bureau,
is in Gland, Switzerland. India became signatory to this convention on in 1981.
The Convention aims to halt the loss of wetlands and to ensure the conservation
of fauna and flora and their ecological processes.
Obligations
of parties include:
•
designating one or more wetlands for inclusion in the list of Wetlands of
International
Importance
(e.g. six Ramsar wetlands in India).
•
promoting wise judicious use of wetlands, including mangroves.
•
promoting conservation of wetlands through establishment of nature reserves.
•
irrespective of their listing under the Convention and managing wetlands for
the benefit of water fowl.
•
promoting training in the field of wetland research, managing and warding.
•
consulting with other parties about implementation of the convention,
especially with regard to trans frontier wetlands, shared water systems, shared
species, and
development
of wetland projects.convention, nations committed themselves to protecting the
ozone layer and to co-operate with each other in scientific research to improve
understanding of the atmospheric processes and serious consequences of ozone
depletion. The convention provides for future protocols and specified
procedures for amendment and dispute settlement.
.
Ă Montreal Protocol
The
United Nations Environment Programme (UNEP) has been addressing this issue
since
1977. Under the auspices of UNEP, the nations of the world arrived at The
Convention
for the Protection of the Ozone Layer in Vienna in 1985. Through this
convention,
nations committed themselves to protecting the ozone layer and to co-operate with
each other in scientific research to improve understanding of the atmospheric
processes and serious consequences of ozone depletion. The convention provides
for future protocols and specified procedures for amendment and dispute
settlement. To pursue the objectives of convention for the protection of ozone
layer the Montreal Protocol on Substances that deplete the Ozone layer was
agreed to by nations in 1987 and has since been amended five times so far. Its
control provisions were strengthened through five amendments to the Protocol
adopted in London (1990), Copenhagen (1992), Vienna (1995), Montreal (1997) and
Beijing (1999). The Protocol aims to reduce and eventually eliminate the
emission of man-made ozone depleting substances. The Vienna Convention and
Montreal Protocol are considered as highly effective regime for reducing and
possibly, in the future, eliminating –emissions of ozone depleting chemicals into
the atmosphere.
The Montreal
Protocol uses three kinds of provisions as economic
incentives to encourage participation and compliance with the Protocol’s
control regime;
(1)
entry into forcerequirements,
(2)
controls on trade with non-parties, and
(3)
research and technology transfer benefits. The Protocol promotes technology
transfer to developing countries, thereby offering economic incentives for
developing countries to join and comply through a network of 507 monitoring
stations located all over the country. Under the National Ambient Air Quality
Monitoring Programme, 290 station covering over 90 cities/towns are being monitored
by the CPCB (Central Pollution Control Board).
Ă The Convention on Biological Diversity
(CBD)
was adopted during the United Nations Conference on Environment and Development
(UNCED - or the “Earth Summit”) in Rio de Janeiro on 5 June 1992.
Ă NATIONAL
ENVIRONMENTAL AGENCIES
The Ministry of
Environment and Forest, Central Pollution Control Board, Indian Board
for Wildlife are
the main national environmental agencies.
The
Central Pollution Control Board (CPCB), is statutory organisation, was
constituted in September, 1974 under the Water (Prevention and Control of
Pollution) Act, 1974. Further, CPCB was entrusted with the powers and functions
under the Air (Prevention and Control of Pollution) Act, 1981. It serves as a
field formation and also provides technical services to the Ministry of
Environment and Forests of the provisions of the Environment (Protection) Act,
1986.
Principal functions
of the CPCB, as spelt out in the Water (Prevention and Control
of Pollution) Act, 1974, and the Air (Prevention and Control of Pollution) Act,
1981,
(i) to promote cleanliness of streams and wells in different areas of the States by prevention, control and abatement of water pollution, and
(i) to promote cleanliness of streams and wells in different areas of the States by prevention, control and abatement of water pollution, and
(ii)
to improve the quality of air and to prevent, control or abate air pollution in
the country. One of the mandates of CPCB is to collect, collate and disseminate
technical
and
statistical data relating to water pollution. Hence, Water Quality Monitoring
(WQM) and Surveillance are of utmost importance.
Environmental
Governance and State Pollution Control Board
The
umbrella Act, EPA (Environmental Protection Agency) 1986 added strength to all preceding
provisions. Special stipulations were made for industrial, vehicular and noise pollution
control in the country.
Ă Indian Board for Wildlife (IBWL)
The
IBWL is the apex advisory body in the field of Wildlife Conservation in the
country and is headed by the Honorable Prime Minister of India. The IBWL has
been reconstituted w.e.f. 7.12.2001. The XXI meeting of the IBWL was held on
21.1.2002 under the Chairmanship of the Honorable Prime Minister of India at
New Delhi.
