ECO-SENSITIVE ZONES

29 Eco Sensitive Zones notified by The Ministry of Environment, Forest and Climate Change.


ECO-SENSITIVE ZONES
The National Wild Life Action Plan (2002-2016) provided for declaring identified areas around Protected Areas and corridors as ecologically fragile under the Environment (Protection) Act, 1986, wherever necessary. The Indian Board for Wild Life on 21st January, 2002 considered Wild Life Conservation Strategy, 2002 and recommended that lands falling within 10 km of the boundaries of National Parks and Sanctuaries should be notified as eco-fragile zones under Section 3(v) of the Environment (Protection) Act and Rule 5  Sub-Rule 5(viii) & (x) of Environment (Protection) Rules.
          The National Board for Wild Life reviewed the matter and recommended that delineation of eco-sensitive zones would have to be site specific, and relate to regulation, rather than prohibition, of specific activities. The following criteria, as proposed by the Ministry were agreed by the National Board for Wildlife for declaration of Eco-Sensitive Zones around National Parks and Sanctuaries:
i.Complete protection to endemic species in its entire range;
ii.Development processes not to reduce, damage or destroy the habitat  of critically  endangered or any other threatened species;
iii.Protection to biological corridors;
iv.Protection to highly complex and diversified ecosystems susceptible to irreversible damage, like coral reefs, mangroves, etc.;
v.Sites associated with reproductive, breeding or nurturing behaviour of  rare and threatened species;
vi.Existence of pristine forests;
vii.Steep slopes ( more than 60º)

At present the 29 ESZ spread across 10 States notified by the Union Government are spread across Haryana, Gujarat, Jharkhand, Karnataka, Sikkim, Goa, Maharasthra, Rajasthan, Gujarat and Uttarakhand. Jammu and Kashmir government has identified 12 ESZ around National Parks and Sanctuaries in the state, including those around the Gulmarg Wildlife Sanctuary, Dachigam National Park, Hemis High Altitude National Park and Changthang Cold Desert Wildlife Sanctuary.


The conservation and sustainable development of ESZ is achieved through preparation of Zonal Master Plans for them on a scientific basis with adequate participation of the local communities and line departments of the state government.

El Nino & La Nina

El Niño is defined by prolonged warming in the Pacific Ocean sea surface temperatures when compared with the average value. El Niño and La Niña are opposite phases of what is known as the El Niño-Southern Oscillation (ENSO) cycle. The ENSO cycle is a scientific term that describes the fluctuations in temperature between the ocean and atmosphere in the east-central Equatorial Pacific. The ENSO cycle, both El Niño and La Niña, causes global changes of both temperatures and rainfall
The first signs of an El Niño are a weakening of the Walker circulation or trade winds and strengthening of the Hadley circulation and may include
1.  Rise in surface pressure over the Indian Ocean, Indonesia, and Australia
2.  Fall in air pressure over Tahiti and the rest of the central and eastern Pacific Ocean
3.  Trade winds in the south Pacific weaken or head east
4.  Warm air rises near Peru, causing rain in the northern Peruvian deserts
La Niña is sometimes referred to as the cold phase of ENSO and El Niño as the warm phase of ENSO. These deviations from normal surface temperatures can have large-scale impacts not only on ocean processes, but also on global weather and climate. La Niña caused a drop in sea surface temperatures over Southeast Asia by 2 °C. It also caused heavy rains over Malaysia, the Philippines, and Indonesia. La Niña causes mostly the opposite effects of El Niño
2014 hottest year on record: US scientists
According to US scientists, year 2014 was the hottest year on record, with global average temperature increasing about 0.8 degrees Celsius since 1880. It was revealed by two separate analyses carried out by NASA and National Oceanic and Atmospheric Administration (NOAA).However, 2014’s record warmth occurred during an El Nino-neutral year.

Acid Rain:

Acid rain occurs due to the presence of certain pollutants in the atmosphere. Acid rain can be caused due to combustion of fossil fuels or erupting volcanoes or rotting vegetation which release sulfur dioxide and nitrogen oxides into the atmosphere. Acid rain is a known  environmental problem that can have serious effect on human health, wildlife and aquatic species.

Ocean Acidification:

It is a direct impact of excessive production of CO2. 25% of CO2 produced by humans. The ocean acidity has increased by the last 250 years but by 2100, it may shoot up by 150%. The main impact is on shellfish and plankton in the same way as human osteoporosis.

Ozone Layer Depletion

The ozone layer is an invisible layer of protection around the planet that protects us from the sun’s harmful rays. Depletion of the crucial Ozone layer of the atmosphere is attributed to pollution caused by Chlorine and Bromide found in Chloro-floro carbons (CFC’s). Once these toxic gases reach the upper atmosphere, they cause a hole in the ozone layer, the biggest of which is above the Antarctic. The CFC’s are banned in many industries and consumer products. Ozone layer is valuable because it prevents harmful UV radiation from reaching the earth. This is one of the most important current environmental problem.

ENVIRONMENTAL LAWS

1.    Air (Prevention and Control of Pollution) Act, 1981.  It was amended in 1987
2.     Biological Diversity Act, 2002 National Biodiversity Authority (NBA)is a statutory autonomous body, headquartered in Chennai, under the Ministry of Environment and Forests, Government of India established in 2003 to implement the provisions under the Act
3.    Environment Protection Act, 1986. The purpose of the Act is to implement the decisions of the United Nations Conference on the Human Environments they relate to the protection and improvement of the human environment and the prevention of hazards to human beings, other living creatures, plants and property.
4.     Forest (Conservation) Act, 1980
5.     National Green Tribunal Act, 2010 to provide for the establishment of a National Green Tribunal for the effective and expeditious disposal of cases relating to environmental protection and conservation of forests and other natural resources including enforcement of any legal right relating to environment and giving relief and compensation for damages to persons and property and for matters connected therewith or incidental thereto.
6.    Public Liability Insurance Act 1991 is to provide for damages to victims of an accident which occurs as a result of handling any hazardous substance. The Act applies to all owners associated with the production or handling of any hazardous chemicals.
7.    The Water (Prevention and Control of Pollution) Act was enacted in 1974 to provide for the prevention and control of water pollution, and for the maintaining or restoring of wholesomeness of water in the country. The Act was amended in 1988.

8.    The Water (Prevention and Control of Pollution) Cess Act was enacted in 1977, to provide for the levy and collection of a cess on water consumed by persons operating and carrying on certain types of industrial activities. This cess is collected with a view to augment the resources of the Central Board and the State Boards for the prevention and control of water pollution constituted under the Water (Prevention and Control of Pollution) Act, 1974. The Act was last amended in 2003.
