  • [pib] 13th COP of the Convention on the Conservation of Migratory Species of Wild Animals (CMS)

     

    The 13th Conference of Parties (COP) of the Convention on the Conservation of Migratory Species of Wild Animals (CMS) is going to be hosted by India at Gandhinagar in Gujarat.

    13th COP of CMS

    • The theme of CMS COP13 in India is, “Migratory species connect the planet and we welcome them home.
    • The CMS COP 13 logo is inspired by ‘Kolam’, a traditional artform from southern India.
    • In the logo of CMS COP-13, Kolam art form is used to depict key migratory species in India like Amur falcon, humpback whale and marine turtles.
    • The mascot for CMS COP13, “Gibi – The Great Indian Bustard” is a critically endangered species which has been accorded the highest protection status under the Wildlife Protection Act, 1972.

    About CMS

    • CMS is an international treaty concluded under aegis of UN Environment Programme (UNEP), concerned with conservation of wildlife and habitats on a global scale.
    • It is commonly abbreviated as Convention on Migratory Species (CMS) or the Bonn Convention.
    • It aims to conserve terrestrial, marine and avian migratory species throughout their range.
    • It was signed in 1979 in Bonn (hence the name), Germany and entered into force in 1983.
    • Its headquarters are in Bonn, Germany.
    • CMS is only global and UN-based intergovernmental organization established exclusively for conservation and management of terrestrial, aquatic and avian migratory species throughout their range.

    Prospects for India

    • As the host, India shall be designated the President for the next three years.
    • India is Signatory to the CMS since 1983.
    • India has been taking necessary actions to protect and conserve migratory marine species.
    • Seven species that include Dugong, Whale Shark, Marine Turtle (two species), have been identified for preparation of Conservation and Recovery Action Plan.

    Other facts

    • The Indian sub-continent is also part of the major bird flyway network, i.e, the Central Asian Flyway (CAF) that covers areas between the Arctic and Indian Oceans, and covers at least 279 populations of 182 migratory water bird species, including 29 globally threatened species.
    • India is home to several migratory species of wildlife including snow leopard, Amur falcons, bar headed Geese, black necked cranes, marine turtles, dugongs, humpbacked whales, etc.
    • It has signed non legally binding MOU with CMS on the conservation and management of Siberian Cranes (1998), Marine Turtles (2007), Dugongs (2008) and Raptors (2016).

  • Energy stored in wastewater

    The world generates about 380 trillion litres (tl) wastewater every year. These stores vast amounts of energy, nutrients for fertilizers besides, of course, water, according to recent study by the UN Institute for Water Environment and Health (UNU-INWEH).

    Energy in wastewater

    • In principle, nutrients such as nitrogen, phosphorous and potassium recovered from wastewater produced annually can offset 13.4 per cent of global demand to produce fertilizers.
    • Assuming full-energy recovery, the study estimated, current wastewater volume could provide enough methane fuel to power 196 million households by 2030 and 239 million households by 2050.
    • Usable water reclaimed from wastewater can irrigate up to 31 million hectares (mha) of land, the study claimed.
    • The volume of wastewater being generated is projected to rise roughly 24 per cent by 2030 to 470 tl and 51 per cent by 2050 to 574 tl.
    • Treating wastewater efficiently can go a long way in achieving the UN-mandated sustainable development goals (SDG).

    About UNU-INWEH

    • UNU-INWEH acts as the “UN Think Tank on Water” and contributes to the resolution of the global water challenge through a unique programme of applied research and education.
    • It conceives, develops, and manages water initiatives that help developing countries build their capacity for lasting improvements in human and ecosystem health, and overall reduction in poverty.
    • The  University is not a traditional university in the sense of having a faculty, campus, or students.
    • They respond directly to the regional and global water crisis and facilitate efforts to meet UN Development goals by providing a scientific evidence base.
    • UNU-INWEH carries out its work in cooperation with other research institutions, international organizations, individual scholars, and scientists throughout the world.

  • Forest Fire: Its Prevention and Management

    The Minister for Environment, Forests and Climate Change (MoEFCC) has informed that area covering 93,273 hectares was affected by forest fires in 2019. Most of the fires have been “ground fires” burning ground vegetation.

    Measures to curb Forest fires:

    1) National Action Plan on Forest Fires

    • The MoEFCC has prepared a National Action Plan on Forest Fires in 2018 after several rounds of consultation with all states and UTs.
    • The objective of this plan is to minimize forest fires by informing, enabling and empowering forest fringe communities and incentivizing them to work in tandem with the State Forest Departments.
    • The plan also intends to substantially reduce the vulnerability of forests across diverse forest ecosystems in the country against fire hazards, enhance capabilities of forest personnel and institutions in fighting fires and swift recovery subsequent to fire incidents.

    2) Forest Fire Prevention and Management scheme

    • The MoEFCC provides forest fire prevention and management measures under the Centrally Sponsored Forest Fire Prevention and Management (FPM) scheme.
    • The FPM is the only centrally funded program specifically dedicated to assist the states in dealing with forest fires.
    • The FPM replaced the Intensification of Forest Management Scheme (IFMS) in 2017. By revamping the IFMS, the FPM has increased the amount dedicated for forest fire work.
    • Funds allocated under the FPM are according to the 90:10 ratio of central to state funding in the Northeast and Western Himalayan regions and 60:40 ratio for all other states.
    • Nodal officers for forest fire prevention and control have been appointed in each state.

  • Ujh Multi-purpose Project

     

    The Union government has approved a nearly ₹6,000-crore multi-purpose project for the Ujh multi-purpose project.

    Ujh Multi-purpose Project

    • The project will store around 781 million cubic meters of water of river Ujh, a tributary of river Ravi.
    • It aims to provide uninterrupted water for irrigation to farmers in J&K’s Kathua district and to produce power.
    • After completion of the project, utilization of waters of eastern rivers allotted to India as per the Indus Water Treaty would be enhanced by utilising the flow that presently goes across the border to Pakistan.

    Back2Basics

    Indus Waters Treaty, 1960

    • The IWT is a water-distribution treaty between India and Pakistan, brokered by the World Bank signed in Karachi in 1960.
    • According to this agreement, control over the water flowing in three “eastern” rivers of India — the Beas, the Ravi and the Sutlej was given to India
    • The control over the water flowing in three “western” rivers of India — the Indus, the Chenab and the Jhelum was given to Pakistan
    • The treaty allowed India to use western rivers water for limited irrigation use and unrestricted use for power generation, domestic, industrial and non-consumptive uses such as navigation, floating of property, fish culture, etc. while laying down precise regulations for India to build projects
    • India has also been given the right to generate hydroelectricity through run of the river (RoR) projects on the Western Rivers which, subject to specific criteria for design and operation is unrestricted.

    Present Status of Development

    • To utilize the waters of the Eastern rivers which have been allocated to India for exclusive use, India has constructed Bhakra Dam on Satluj, Pong and Pandoh Dam on Beas and Thein (Ranjitsagar) on Ravi.
    • These storage works, together with other works like Beas-Sutlej Link, Madhopur-Beas Link, Indira Gandhi Nahar Project etc has helped India utilize nearly entire share (95 %) of waters of Eastern rivers.
    • However, about 2 MAF of water annually from Ravi is reported to be still flowing unutilized to Pakistan below Madhopur.
    • The three projects will help India to utilize its entire share of waters given under the Indus Waters Treaty 1960:

    I. Resumption of Construction of Shahpurkandi project

    • It is a dam project under construction on Ravi River.

    II. Construction of Ujh multipurpose project

    • It is a dam project under construction on Ujh, a tributary of Ravi River.

    III. 2nd Ravi Beas link below Ujh

    • This project is being planned to tap excess water flowing down to Pakistan through river Ravi, even after construction of Thein Dam.
    • It aims constructing a barrage across river Ravi for diverting water through a  tunnel link to Beas basin.

  • Species in news: Flame-throated Bulbul

    The flame-throated bulbul, also called the Rubigula, was chosen as the mascot of the 36th National Games to be held in Goa. It is the State bird of Goa.

    Flame-throated Bulbul

    IUCN status: Least Concern

    • The Flame-throated Bulbul is endemic to southern peninsular India where it is locally distributed in southern Andhra Pradesh, eastern Karnataka, Goa, Orissa, eastern Kerala and northern Tamil Nadu.
    • It prefer habitats like rocky, scrub-covered hills mostly in the Eastern Ghats and central peninsular India but also in some places in the Western Ghats.
    • It is a Schedule – IV bird under the Wildlife (Protection) Act, 1972.

  • Plantation Corporation of India

    The Union government is likely to announce the setting up of a Plantation Corporation of India in the upcoming budget.

    Plantation Corporation of India

    • The PCI will subsume all afforestation-related schemes currently underway in India including the Green India Mission, National Afforestation Programme and compensatory afforestation.
    • The corporation will use Compensatory Afforestation Fund (CAF) money to undertake the plantations and investment will also come from the global pension fund.
    • CAF is a huge corpus of money collected from projects proponents for diverting forest land to be used for non-forestry activity.

    Issues with PCI

    • Critics have raised concerns over the move’s impact on the federal structure of forest governance in the country.
    • While forests are a concurrent subject, land-related issues are the responsibility of the states.

  • Reintroduction of African Cheetahs in Indian forests

     

    The Supreme Court lifted its seven-year stay on a proposal to introduce African cheetahs from Namibia into the Indian habitat on an experimental basis. The plan was to revive the Indian cheetah population.

    Asiatic cheetahs in India

    • In 1947, Maharaja Ramanuj Pratap Singh of Deoghar of Koriya, Chhattisgarh — who was infamous for shooting over 1,150 tigers — reportedly killed the last known Asiatic cheetah in India.
    • In that year, a few miles from Ramgarh village in the state, the Maharaja killed three of the animals — brothers — during a night drive.
    • After that, the Maharaja’s kin continued to report the presence of a few stragglers in the forests of Surguja district, including a pregnant female, up until the late 1960s.
    • Some more unconfirmed sightings were reported in 1951 and 1952, from the Orissa-Andhra Pradesh border and Chittoor district.
    • The latter sighting is generally accepted to be the final credible sighting of a cheetah in India. In 1952, the cheetah was officially declared extinct from India.

    African cheetah and Asiatic cheetah

    • Before Namibia, India had approached Iran for Asiatic cheetahs, but had been refused.
    • The Asiatic cheetah is classified as a “critically endangered” species by the IUCN Red List, and is believed to survive only in Iran.
    • From 400 in the 1990s, their numbers are estimated to have plummetted to 50-70 today, because of poaching, hunting of their main prey (gazelles) and encroachment on their habitat.
    • ‘Critically endangered’ means that the species faces an extremely high risk of extinction in the wild.

    Why does NTCA want to reintroduce cheetahs?

    • A section of conservationists has long advocated the reintroduction of the species in the country.
    • Reintroductions of large carnivores have increasingly been recognised as a strategy to conserve threatened species and restore ecosystem functions.
    • The cheetah is the only large carnivore that has been extirpated, mainly by over-hunting in India in historical times.
    • India now has the economic ability to consider restoring its lost natural heritage for ethical as well as ecological reasons.

    Why was the project halted?

    • The court was also worried whether the African cheetahs would find the sanctuary a favourable clime as far as abundance of prey is concerned.
    • Those who challenged the plan argued that the habitat of cheetahs needed to support a genetically viable population.

    What did court say?

    • The Supreme Court made it clear that a proper survey should be done to identify the best possible habitat for the cheetahs.
    • Every effort should be taken to ensure that they adapt to the Indian conditions.
    • The committee would help, advice and monitor the NTCA on these issues. The action of the introduction of the animal would be left to the NTCA’s discretion.

  • 10 more wetlands from India get the Ramsar site tag

    Ramsar has declared 10 more wetland sites from India as sites of international importance.

    News Ramsar Wetlands

    With this, the numbers of Ramsar sites in India are now 37 and the surface area covered by these sites is now 1,067,939 hectares.

    1. Maharashtra gets its first Ramsar site (Nandur Madhameshwar) ,
    2. Punjab which already had 3 Ramsar sites adds 3 more (Keshopur-Miani, Beas Conservation Reserve, Nangal) and
    3. UP with 1 Ramsar site has added 6 more (Nawabganj, Parvati Agra, Saman, Samaspur, Sandi and Sarsai Nawar).

    Why conserve wetlands?

    • Wetlands provide a wide range of important resources and ecosystem services such as food, water, fibre, groundwater recharge, water purification, flood moderation, erosion control and climate regulation.
    • They are, in fact, are a major source of water and our main supply of freshwater comes from an array of wetlands which help soak rainfall and recharge groundwater.

    Back2Basics

    Ramsar Convention

    • The Convention on Wetlands of International Importance (better known as the Ramsar Convention) is an international agreement promoting the conservation and wise use of wetlands.
    • It is the only global treaty to focus on a single ecosystem.
    • The convention was adopted in the Iranian city of Ramsar in 1971 and came into force in 1975.
    • Traditionally viewed as a wasteland or breeding ground of disease, wetlands actually provide freshwater and food, and serve as nature’s shock absorber.
    • Wetlands, critical for biodiversity, are disappearing rapidly, with recent estimates showing that 64% or more of the world’s wetlands have vanished since 1900.
    • Major changes in land use for agriculture and grazing, water diversion for dams and canals and infrastructure development are considered to be some of the main causes of loss and degradation of wetlands.

  • Biorock technique for Coral Restoration

    The Zoological Survey of India (ZSI), with help from Gujarat’s forest department, is attempting for the first time a process to restore coral reefs using biorock or mineral accretion technology.

    What is Biorock Technique?

    • Biorock is the name given to the substance formed by electro accumulation of minerals dissolved in seawater on steel structures that are lowered onto the sea bed and are connected to a power source, in this case solar panels that float on the surface.
    • The technology works by passing a small amount of electrical current through electrodes in the water.
    • When a positively charged anode and negatively charged cathode are placed on the sea floor, with an electric current flowing between them, calcium ions combine with carbonate ions and adhere to the structure (cathode).
    • This results in calcium carbonate formation. Coral larvae adhere to the CaCO3 and grow quickly.
    • Fragments of broken corals are also tied to the biorock structure, where they are able to grow at least four to six times faster than their actual growth as they need not spend their energy in building their own calcium carbonate skeletons.

    Significance of the move

    • The technology helps corals, including the highly sensitive branching corals, to counter the threats posed by global warming.
    • In 2015, the same group of ZSI scientists had successfully restored branching coral species (staghorn corals) belonging to the family Acroporidae (Acropora formosa, Acropora humilis, Montipora digitata) that had gone extinct about 10,000 years ago to the Gulf of Kachchh.

    Back2Basics

    Coral Bleaching

    • The stunning colours in corals come from a marine algae called zooxanthellae, which live inside their tissues.
    • This algae provides the corals with an easy food supply thanks to photosynthesis, which gives the corals energy, allowing them to grow and reproduce.
    • When corals get stressed, from things such as heat or pollution, they react by expelling this algae, leaving a ghostly, transparent skeleton behind.
    • This is known as ‘coral bleaching’. Some corals can feed themselves, but without the zooxanthellae most corals starve.

  • Threat of Invasive Alien Species in Shola Forests of the Nilgiris

     

    Shola Forests

    • The Shola forests of South India derive their name from the Tamil word solai, which means a ‘tropical rain forest’.
    • Classified as ‘Southern Montane Wet Temperate Forest’ the Sholas are found in the upper reaches of the Nilgiris, Anamalais, Palni hills, Kalakadu, Mundanthurai and Kanyakumari in the states of Tamil Nadu and Kerala.
    • These forests are found sheltered in valleys with sufficient moisture and proper drainage, at an altitude of more than 1,500 metres.

    Vegetation

    • The upper reaches are covered with grasslands, known as Shola grasslands.
    • The vegetation that grows in Shola forests is evergreen. The trees are stunted and have many branches. Their rounded and dense canopies appear in different colours.
    • Generally, the leaves are small in size and leathery. Red-coloured young leaves turning into different colours on maturity is a prominent characteristic of the Shola forests.
    • Epiphytes like lichens, ferns and bryophytes usually grow on the trees.
    • The occurrence of Himalayan plants like rhododendron in these Shola forests is a mystery.

    Significance of Sholas

    • Sholas thus act as ‘overhead water tanks’. They play a major role in conserving water supply of the Nilgiris’ streams.
    • The trees are slow-growing varieties which produce timber of little or no value and probably take at least a century to mature.
    • The rolling grasslands found on top of the Western Ghats, enhance the beauty of the region. Usually, Shola forests and grasslands are found in a ratio of 1:5.
    • The rain received from the Southwest and Northeast monsoons is harvested by the Shola forest-grassland ecosystem, leading to the formation of the Bhavani river that finally drains into the Cauvery.
    • Thus, the Shola forest-grassland ecosystem of the Nilgiris, also supports the prosperity of Cauvery delta farmers.
    • As tree species of the montane, evergreen forests are flammable, regeneration of any Shola tree species is completely prevented except for Rhododendron nilagiricum, the only Shola tree that can tolerate fire.

    Threats to Sholas

    • Unfortunately, the Sholas have begun to gradually shrink due to the introduction of alien plant species and annual fire occurrences.
    • Alien species like Sticky Snakeroot, Gorse and Scotch Broom introduced during British rule, have encroached upon the grasslands.
    • During 1840, tree species such as Acacia and Eucalyptus were introduced from Australia.
    • Afterwards, between 1886 and 1891, Pine and Cypress were introduced, again from Australia. As the alien species grew, the forests and grasslands gradually became degraded and shrank.
    • In addition, unscientific agricultural practices like growing tea on the slopes, cattle grazing and fuel wood collection have become serious causes for degradation.
    • Unregulated tourism has created concrete jungles, traffic congestion and caused the generation of garbage.

    Wrath of Eucalyptus

    • During 1849, the extent of Shola forests was 8,600 hectares (ha), grasslands 29,875 ha and agriculture was 10,875 ha.
    • No wattle or eucalyptus was planted in the area at that time.
    • The comparison of the results of the 1849 and 1992 studies shows that cultivation of tea, wattle and eucalyptus has reduced the Shola forest-grassland ecosystem to a great extent.

    Protective measures

    • After realizing the seriousness of the situation, the government banned the planting of wattle and eucalyptus completely in 1987.
    • Ecological restoration and biodiversity conservation were given importance.
    • Under the Hill Area Development Programme since the mid-1980s, seedlings have been planted in degraded patches and protected with chain-link fences to restore the forests.
    • Special Shola forest protection committees were formed involving teachers, nature lovers, ecologists, environmentalists, students and villagers in the Nilgiris.
    • They were motivated to remove plastic garbage from the nearby forests, protect Shola trees, remove alien species and learn about the importance of the Sholas.
    • Presently, the Tamil Nadu forest department is now focusing on eradicating wattle, providing fencing and planting shola seedlings in degraded shola forests.
