    November 2020: Current Affairs Environment & Ecology UPSC Notes | EduRevMini Ganga Quest
    • Ganga Quest is a bilingual pan-Indian quiz to increase public participation and promote youth in the Namami Gange program.
  3. Suggestion on the innovative ways in which Namami Gange can engage in activities throughout the year.
    • In 2014, Namami Gange Programme was launched to accomplish the twin objectives of effective abatement of pollution and conservation, and rejuvenation of Ganga.

➤ Government Initiatives on River Ganga

  1. Ganga Action Plan: It was the first River Action Plan adopted in 1985 by the Ministry of Environment, Forestry and Climate Change to improve water quality through domestic sewage interception, diversion and treatment. 
    • An extension to this plan, which aims to clean the Ganga River under Phase 2 of the Ganga Action Plan, is the National River Conservation Plan.
  2. National River Ganga Basin Authority: It was formed by India's Government in the year 2009 under Section-3 of the Environment Protection Act 1986.
  3. Clean Ganga Fund: In 2014, it was formed for cleaning up of the Ganga, setting up of waste treatment plants and conservation of biotic diversity of the river.
  4. Bhuvan-Ganga Web App: It ensures the public's involvement in the monitoring of pollution entering the river Ganga.
  5. Waste Disposal Ban: The National Green Tribunal (NGT) prohibited the disposal of any waste in the Ganga in 2017.

Exotic Animals Rescued 

Recently, 6 blue or hyacinth macaws and two capuchin monkeys have been released in the Assam State Zoo-cum-Botanical Garden in Guwahati.

Earlier, there had been a large consignment of exotic animals confiscated by the Revenue Intelligence Directorate in the same region, (DRI)

Major points: 

➤ Illegal Wildlife Trade-Related Provisions

  • Under Section 111 of the Customs Act, 1962, read in conjunction with the Convention on International Trade's provisions in Endangered Species of Wild Fauna and Flora (CITES) and the Foreign Trade Policy (Import-Export Policy) of India, illegal exotic animals are confiscated. 
  • Sections 48 and 49 of the Wildlife Protection Act, 1972 also prohibit trade or trade in wild animals, articles or trophies containing animals. 

Concerns

  • Against the background of Covid-19, the possibility of the spread of zoonotic diseases due to smuggling in such exotic species is increasingly becoming a global concern. 
  • After the smuggling of narcotics, counterfeit goods and human trafficking, the illegal wildlife trade was ranked the 4th largest transnational organized crime worldwide. 
  • Due to their proximity to Bangladesh and Myanmar's borders, and to Thailand, West Bengal and northeast India are vulnerable to cross-border smuggling of wildlife. 
  • Apart from foreign currency's illegal movement, many international organisations involved in wildlife crime use the Indo-Bangladesh Border for various other illegal activities, such as drug smuggling, commercial goods, and even gun-running.

Blue Macaws

  • Scientific Name: Anodorhyn- chus hyacinthinus.
    November 2020: Current Affairs Environment & Ecology UPSC Notes | EduRevBlue Macaw
  • Native to central and eastern South America, it is a parrot. 
  • It is longer than any other parrot species with a length of about one meter and is the largest macaw and the largest flying parrot species. 
  • Threat: The loss of habitat and the trapping of wild birds for the pet trade has suffered a heavy toll on their wild population. 
  • Protection Status:
    1. IUCN Red List: Vulnerable.
    2. CITES Appendix I.

Capuchin Monkeys

  • Genus: Cebus
    November 2020: Current Affairs Environment & Ecology UPSC Notes | EduRevCapuchin Monkey
  • Capuchin Monkeys, also called sapajou, is a common Central and South American primate found in tropical forests from Nicaragua to Paraguay.
  • They are named for their "caps" of hair, which resemble Capuchin monks' cowls.
  • Protection Status:
    IUCN Red List: Least concerned.

Declaring ESA Unconstitutional

The Supreme Court (SC) recently moved a Kerala-based farmers' NGO to declare the draft notification on the Western Ghats Ecologically Sensitive Area (ESA) unconstitutional.
November 2020: Current Affairs Environment & Ecology UPSC Notes | EduRevWestern Ghats

November 2020: Current Affairs Environment & Ecology UPSC Notes | EduRev

It sought direction from the government not to implement the reports on the conservation of the Western Ghats by the Madhav Gadgil and Kasturirangan committees. 

Context

  • The Western Ghats Ecology Expert Panel (WGEEP), also known as the Gadgil Committee, and the High-Level Working Group of the Kasturirangan Committee were established to conserve and protect the biodiversity of the Western Ghats, while at the same time enabling the region's sustainable and inclusive development. 
  • They recommended that the ESA be declared as identified geographical areas falling within the six states of Kerala, Karnataka, Goa, Maharashtra, Gujarat and Tamil Nadu.
  • In 2018, a draft notification concerning the same was issued specifying the areas to be notified in the ESA.

Ecologically Sensitive Areas

  • Protected Areas, National Parks and Wildlife Sanctuaries are located within 10 km of Eco-Sensitive Zones or Ecologically Fragile Areas. 
  • ESAs are reported under the Environment (Protection) Act 1986 by the MoEFCC. 
  • Objective: To regulate certain activities in the vicinity of national parks and wildlife sanctuaries in order to minimize the adverse effects on the fragile ecosystem of protected areas.
    1. Red sectors (highly polluting industries) should be strictly prohibited.
    2. Exclusion from the scope of ESAs of inhabited regions and plantations makes it a pro-farmer approach.

Issues underlined by the petition

  • The draft notification would declare 123 agricultural villages in Kerala to be ESA, converting the region's semi-urban villages into forests without roads and facilities. It will affect 22 lakh people and will cripple Kerala's economy. 
  • The Centre incorrectly branded individuals residing in the Western Ghats region as "destroyers of the biodiversity and agents of ecological damage." 
  • Also, it suggested that ESA be restricted to reserved forests and protected areas in Kerala.

➤ Gadgil Committee

  • It recommended that all Western Ghats be declared ESA with only limited development permission in graded zones. O The Western Ghats were classified into ESA 1, 2 and 3, of which ESA-1 is a high priority zone in which almost all development activities (mining, thermal power plants, etc.) were to be limited. The Western Ghats Ecology Authority (WGEA) was also recommended to be established as a statutory authority under the Ministry of Environment, Forestry and Climate Change (MoEFCC) with powers under Section 3 of the Environment (Protection) Act, 1986. 
  • It was criticized for being more environmentally friendly and not in harmony with the realities of the earth. 

Kasturirangan Committee

  • In contrast to the Gadgil report system, the aim was to balance development and environmental protection. The major recommendations of the Committee were: 
  • Instead of the Western Ghats' total area, only 37% of the total area to be transferred under the ESA is required. 
  • A complete prohibition on ESA mining, quarrying and sand mining. 
  • No thermal power projects should be permitted, and hydropower projects should only be permitted after a detailed study.

Panna Biosphere Reserve

The Panna Biosphere Reserve (PBR) has recently been included in the World Network of Biosphere Reserves by the United Nations Educational, Scientific and Cultural Organization (UNESCO) (WNBR).

  • In 1974, UNESCO launched the idea of a biosphere reserve under the MAB with the aim of obtaining international cooperation for the conservation of the biosphere.

New Species in Andaman

A new genus of treefrog from the Andaman Islands, the Striped Bubble-nest frog, has recently been reported by a group of scientists.
November 2020: Current Affairs Environment & Ecology UPSC Notes | EduRevStriped Bubble-nest frog

Core Points 

Biological Name : Rohanixalus vittatus

  • The Striped Bubble-nest frog belongs to the Rhacophoridae genus of the Old World family of treefrogs. 
  • This is the first report from the Andaman Islands of a tree frog species. 
  • Bodily Attributes: Small and thin body (2-3 cm long). O A pair of lateral lines of a contrasting colour on any side of the body, either. The upper body is scattered with minute brown speckles. 
  • Light green-coloured eggs set in nests of arboreal bubbles. 

There are several unique behavioural traits in the genus: 

  1. Maternal egg attendance:
    • The female (mother) takes care of the egg clutches until she hatches and helps to release the tadpoles into the water.
    • The female sits over the eggs during the first three days after egg laying and produces a gelatinous secretion with which she glazes (covers) the egg mass by moving her legs clockwise. This behaviour provides the eggs laid on exposed leaf surfaces with the necessary moisture and protects them against insect predation.
  2. Attendance of Community Eggs:
    • Arboreal means living in trees or related trees or they are also referred to as Asian Glass Frog or see-through frog.
    • While most glass frogs' general background colouration is mainly lime green, some family members have translucent abdominal skin (allowing light to pass through). The internal viscera, including the liver, heart, and gastrointestinal tract, are visible through this translucent skin, hence the common name.
  3. Many egg clutches (over 50) on a single leaf or plant at different developmental stages. In a behaviour known as 'community' egg attendance, multiple women typically attend such clutches.
  4. Frequent male-male fighting to mate with a woman involves pushing, kicking and dislodging.

Earthquake Concentrations in Dharchula Region

At the Wadia Institute of Himalayan Geology (WIHG), scientists recently discovered large concentrations of earthquakes of micro and moderate magnitude in the Dharchula region and adjacent Kumaon Himalaya areas. 

  • Under the Department, WIHG is an autonomous institute  Government of India, Science and Technology (DST)

Core Points 

➤ Position

  • The main concentration is in an area around 45 km from the new Kailash Mansarovar road, connecting Dharchula in Uttarakhand to Lipu Lekh on the border with China.
  • Despite the Himalayas being one of the most tectonically and seismically active regions in the country, the region is known as the Central Seismic Gap (CSG) region. 

A gap is a term used to denote an area with little activity in tectonics. 

Methods

  • Scientists began to research and map the region precisely in order to find out the reason behind it.
  • The occurrence of earthquakes that are crowded (closely located and often felt). With the Ministry of Earth Sciences' support, they set up a seismological network of 15 broadband seismological stations along the Kali River valley to examine the subsurface configuration in the Kumaon Himalaya region.

Earthquakes in India

  • Due to the presence of tectonically active young fold mountains, the Himalayas, India is one of the highly earthquake-affected countries.
  • India has been split into four seismic zones (II, III, IV, and V) on the basis of scientific inputs relating to seismicity, past earthquakes and regional tectonics.

New Ramsar Sites

Ramsar sites, a conservation status conferred by the International Ramsar Convention on Wetlands, have recently been declared the Meteor lake at Lonar in Buldhana district of Maharashtra the Soor Sarovar at Agra. 

  • Kabartal Wetland (Bihar) and Asan Conservation Reserve (Uttrakhand) were also named as Ramsar sites earlier this year.
