  • Places in news: Deepor Beel

    Assam has prohibited community fishing at Deepor Beel, a wetland on the south-western edge of Guwahati and it’s the only Ramsar site.

    Try this PYQ:

    In which one among the following categories of protected areas in India are local people not allowed to collect and use the biomass?

    (a) Biosphere reserves

    (b) National parks

    (c) Wetlands declared under Ramsar convention

    (d) Wildlife sanctuaries

    Deepor Beel

    • Deepor Beel is located to the south-west of Guwahati city, in Kamrup district of Assam, India.
    • It is a permanent freshwater lake, in a former channel of the Brahmaputra River, to the south of the main river.
    • It is a wetland under the Ramsar Convention which has listed since November 2002, for undertaking conservation measures on the basis of its biological and environmental importance.
    • Considered as one of the largest beels in the Brahmaputra valley of Lower Assam, it is categorised as a representative of the wetland type under the Burma monsoon forest biogeographic region.
    • It is also an important bird sanctuary habituating many migrant species.
    • Freshwater fish is a vital protein and source of income for these communities; the health of these people is stated to be directly dependent on the health of this wetland ecosystem.

    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 fresh water 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.

  • Places in news: Dibru-Saikhowa National Park

    PC: Gmaps

    Assam has asked the State’s Forest and Revenue departments to permanently rehabilitate the indigenous forest dwellers of the Dibru-Saikhowa National Park.

    Try this PYQ from CSP 2019:

    Q. Which of the following are in Agasthyamalai Biosphere Reserve?

    (a) Neyyar, Peppara and Shendurney Wildlife Sanctuaries; and Kalakad Mundanthurai Tiger Reserve

    (b) Mudumalai, Sathyamangalam and Wayanad Wildlife Sanctuaries; and Silent Valley National Park

    (c) Kaundinya, Gundla Brahme-swaram and Papikonda Wildlife Sanctuaries; and Mukurthi National Park

    (d) Kawal and Sri Venkateswara Wildlife Sanctuaries; and Nagarjunasagar-Srisailam Tiger Reserve

    Dibru-Saikhowa National Park

    • DSNP is a national park in Assam located in Dibrugarh and Tinsukia districts.
    • It was designated a Biosphere Reserve in July 1997 with an area of 765 sq. km.
    • The park is bounded by the Brahmaputra and Lohit Rivers in the north and the Dibru river in the south.
    • It mainly consists of moist mixed semi-evergreen forests, moist mixed deciduous forests, canebrakes, and grasslands.
    • It is the largest Salix swamp forest in north-eastern India, with a tropical monsoon climate with a hot and wet summer and cool and usually dry winter.

     Why in news?

    • Rehabilitation of some 10,000 people has been hanging fire since 1999 when the Dibru-Saikhowa Wildlife Sanctuary was upgraded to a national park.
    • The park, home to a few wild horses, had been in focus since May when a blowout at an Oil India Limited gas well in the vicinity posed an ecological threat.

    What is the issue?

    • The affected people belong to the Missing community.
    • The forest dwellers of the 425-sq. km. Dibru-Saikhowa National Park has been denied access to government schemes since 1986 through a notification.
    • It allowed them to continue staying until their shifting to a suitable place.
    • The organization said the villagers’ problems started when 765 sq. km. around their habitations was declared a biosphere reserve in 1997, limiting the access of the forest to the community.
    • The hardship compounded in 1999 when the national park came into existence.

  • The climate policy needs new ideas

    The article highlights the issues with the current climate policies which are centred on the inequality.

    Inequality and climate change

    • Inequity is built into the climate treaty, which considers total emissions, size, and population, making India the fourth largest emitter.
    • According to the United Nations, the richest 1% of the global population emits more than two times the emissions of the bottom 50%.
    • .China, with four times the population of the U.S., accounts for 12% of cumulative emissions.
    • India, with a population close to that of China’s, for just 3% of cumulative emissions that lead to global warming.
    • In an urbanized world, two-thirds of emissions arise from the demand of the middle class for infrastructure, mobility, buildings, and diet.
    • Well-being in the urbanized world is reflected in saturation levels of infrastructure.
    • Growth in the developed countries is consumption-driven not production driven.
    • The vaguely worded ‘carbon neutrality’, balancing emitting carbon with absorbing carbon from the atmosphere in forests is a triple whammy for latecomers like India.
    • Such countries already have less energy-intensive pathways that will not encroach on others’ ecological space, a young population, and are growing fast to reach comparable levels of well-being with those already urbanized and in the middle class.

    What changes are required in the policies

    • At present, the focus is on physical quantities which indicates effects on nature.
    • The solutions require analysis of drivers, trends, and patterns of resource use. 
    • This anomaly explains why the link between well-being, energy use, and emissions is not on the global agenda.
    • Modifying unsustainable patterns of natural resource use and ensuring comparable levels of well-being are societal transformations.
    • New thinking must enable politics to acknowledge transformational social goals and the material boundaries of economic activity.

    India’s unique national circumstances

    • India must highlight its unique national circumstances.
    • For example, the meat industry, especially beef, contributes to one-third of global emissions.
    • Indians eat just 4 kg of meat a year compared to those in the European Union who eat about 65 kg.
    • Also to be noted is the fact that the average American household wastes nearly one-third of its food.
    • Transport emissions account for a quarter of global emissions.
    • Transport emissions are the symbol of Western civilization and are not on the global agenda.
    • Rising Asia uses three-quarters of coal drives industry and supports the renewable energy push into cities.
    • India, with abundant reserves and per capita electricity use that is one-tenth that of the U.S., is under pressure to stop using coal.

    Way forward

    • India has the credibility and legitimacy to push an alternate 2050 goal for countries currently with per capita emissions below the global average.
    • These goals should include well-being within ecological limits, the frame of the Sustainable Development Goals, as well as multilateral technological knowledge cooperation around electric vehicles, energy efficiency, building insulation, and a less wasteful diet.

    Conclusion

    Emissions are the symptom, not the cause of the problem. India, in the UN Security Council, must push new ideas based on its civilizational and long-standing alternate values for the transition to sustainability.

  • Places in news: Sea of Galilee

    The Sea of Galilee, well-known in Jewish, Christian, and Islamic lore, has swelled up due to recent rains, according to reports in the Israeli media.

    Do you know?

    The Sea of Galilee Lake Tiberias, Kinneret or Kinnereth is a freshwater lake in Israel. It is the lowest freshwater lake on Earth and the second-lowest lake in the world (after the Dead Sea, a saltwater lake).

    Sea of Galilee

    • The lake lies in northern Israel, between the occupied Golan Heights and the Galilee region. It is fed by underground springs but its major source is the Jordan River.
    • The lake has risen to 209.905 meters below sea level due to heavy rainfall in the surrounding areas.
    • The Jordan flows into the lake and then exits it before ending in the Dead Sea, the saltiest and the lowest point on the planet.
    • Water is not extracted from the Sea of Galilee. But it is considered to be an important barometer of the water situation in Israel.

    Q.Why is a plant called Prosopis juliflora often mentioned in the news?

    (a) Its extract is widely used in cosmetics.

    (b) It tends to reduce the biodiversity in the area in which it grows

    (c) Its extract is used in the pesticides.

    (d) None of the above

    Portulaca Laljii

    • The new species named Portulaca laljii was discovered from the Prakasam district of Andhra Pradesh.
    • It has unique features such as a tuberous root, no hair in its leaf axils, a reddish-pink flower, prolate-shaped fruits, and copper brown seeds without luster.
    • Portulaca Laljii has been named to honor the contribution of Lal Ji Singh, an eminent botanist of the Botanical Survey of India.
    • The species has been placed under the ‘Data Deficient’ category of the IUCN List of Threatened Species because very little information is available about the population of the species.

    Morphological features

    • These morphological features distinguish the species from other species of the genus Portulaca.
    • The flowers, which are reddish-pink in color, are very minute, at about 0.5mm.
    • The plant was found growing in rocky crevices at an altitude of about 1,800 meters above mean sea level, very close to the ground, at about less than 10 cm.
    • The plants belonging genus Portulaca are classified in the category Sun Rose because they flower in bright sunshine.
    • The genus was described by Linnaeus in 1753 as a type genus of the flowering plant family Portulacaceae.

  • [pib] Tso Kar Wetland Complex

    India has added Tso Kar Wetland Complex in Ladakh as its 42nd Ramsar site, which is a second one in the Union Territory (UT) of Ladakh. With this, India now has forty-two Ramsar sites.

    Try this PYQ:

    In which one among the following categories of protected areas in India are local people not allowed to collect and use the biomass?

    (a) Biosphere reserves

    (b) National parks

    (c) Wetlands declared under Ramsar convention

    (d) Wildlife sanctuaries

    Tso Kar Wetland Complex

    • It is a high-altitude wetland complex, consisting of two principal waterbodies, Startsapuk Tso, a freshwater lake of about 438 hectares to the south, and Tso Kar itself, a hypersaline lake of 1800 hectares to the north.
    • It is situated in the Changthang region of Ladakh.
    • It is called Tso Kar, meaning white lake, because of the white salt efflorescence found on the margins due to the evaporation of highly saline water.

    Ecological significance

    • 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, a major source of water and our main supply of freshwater comes from an array of wetlands which help soak rainfall and recharge groundwater.
    • The Tso Kar Basin is an A1 Category Important Bird Area (IBA) as per BirdLife International and a key staging site in the Central Asian Flyway.
    • The site is also one of the most important breeding areas of the Black-necked Crane (Grus nigricollis) in India.

    Back2Basics: Wetlands

    • A wetland is a distinct ecosystem that is flooded by water, either permanently or seasonally, where oxygen-free processes prevail.
    • The primary factor that distinguishes wetlands from other landforms or water bodies is the characteristic vegetation of aquatic plants, adapted to the unique hydric soil.
    • 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.

    What is the Ramsar Convention?

    • The Ramsar Convention on Wetlands of International Importance Especially as Waterfowl Habitat is a treaty for the conservation and sustainable use of such sites.
    • The convention, signed in 1971 in the Iranian city of Ramsar, is one of the oldest inter-governmental accords for preserving the ecological character of wetlands.
    • Also known as the Convention on Wetlands, it aims to develop a global network of wetlands for the conservation of biological diversity and for sustaining human life.
    • Over 170 countries are party to the Ramsar Convention and over 2,000 designated sites covering over 20 crore hectares have been recognised under it.

  • Five years since Paris Agreement, an opportunity to build back better

    This article by the Ambassador of the European Union underscores the need for implementation and action on the commitments made in the Paris Agreement to deal with climate change.

    EU’s commitment to implement Paris Agreement

    • In December 2019, the European Commission launched the European Green Deal — roadmap to achieve climate neutrality in the EU by 2050.
    •  “Next Generation EU” recovery package and our next long-term budget earmark more than half a trillion euros to address climate change.
    • Recently  EU leaders unanimously agreed on the 2030 target of reducing greenhouse gas emissions by at least 55% compared to 1990 levels.

    Impact on low carbon technologies

    • These actions and commitments of the EU towards Paris Agreement will further bring down the costs of low carbon technologies.
    • The cost of solar photovoltaics has already declined by 82% between 2010 and 2019.
    • Achieving the 55% target will even help us to save €100 billion in the next decade and up to €3 trillion by 2050.

    EU working with India on climate actions

    • No government can tackle climate change alone.
    •  India is a key player in this global endeavour.
    • The rapid development of solar and wind energy in India in the last few years is a good example of the action needed worldwide.
    • India has taken a number of very significant flagship initiatives such as the International Solar Alliance, the Coalition for Disaster Resilient Infrastructure and the Leadership Group for Industry Transition.
    • India and Team Europe are engaged to make a success of the forthcoming international gatherings: COP 26 in Glasgow on climate change and COP 15 in Kunming on biodiversity.

    Way forward

    • The international community should come forward with clear strategies for net-zero emissions and to enhance the global level of ambition for 2030.
    • Our global, regional, national, local and individual recovery plans are an opportunity to ‘build back better’.
    • We will also need to foster small individual actions to attain a big collective impact.

    Conclusion

    With climate neutrality as our goal, the world should mobilise its best scientists, business people, policymakers, academics, civil society actors and citizens to protect together something we all share beyond borders and species: our planet.

  • Firefly Bird Diverters’ to save the Great Indian Bustard (GIB)

    The Environment Ministry along with the Wildlife Conservation Society (WCS) India has come up with a unique initiative a “firefly bird diverter” for overhead power lines in areas where Great Indian Bustard (GIB) populations are found in the wild.

    Try this PYQ:

    Q.Which one of the following groups of animals belongs to the category of endangered species?

    (a) Great Indian Bustard, Musk Deer, Red Panda, Asiatic Wild Ass

    (b) Kashmir Stag, Cheetah, Blue Bull, Great Indian Bustard.

    (c) Snow Leopard, Swamp Deer, Rhesus Monkey, Saras (Crane)

    (d) Lion Tailed Macaque, Blue Bull, Hanuman Langur, Cheetah

    Great Indian Bustard

    • The GIB is one of the heaviest flying birds and can weigh up to 15 kg which grows up to one metre in height.
    • In July 2011, the bird was categorised as “critically endangered” by the International Union for Conservation of Nature (IUCN).
    • It is considered the flagship grassland species, representing the health of the grassland ecology.
    • For long, conservationists have been demanding to secure this population, warning that the bird might get extinct in the coming decades.
    • It would become the first mega species to disappear from India after Cheetah in recent times.
    • Till the 1980s, about 1,500-2,000 Great Indian Bustards were spread throughout the western half of India, spanning eleven states.
    • However, with rampant hunting and declining grasslands, their population dwindled.

    Bird Diverters

    • The diverters are called fireflies because they look like fireflies from a distance, shining on power lines in the night.
    • GIBs are one of the heaviest flying birds in India. Therefore, when they encounter these wires, they are unable to change the direction of their flight.
    • Death is most cases is due to impact with the wires and not due to electrocution.
    • The diverter will not only save GIB but other species of large birds, including migratory birds.

    Why such a move?

    • GIB is one of the most critically threatened species in India, with less than 150 birds left in the wild.
    • A report has pointed out that power lines, especially high-voltage transmission lines with multiple overhead wires, are the most important current threat for GIBs in the Thar region.
    • They are causing unsustainably high mortality in about 15% of their population.

  • Bihar to change Kosi’s course to save the ancient site

    The Bihar government will try to divert the course of the mighty Kosi River in Bhagalpur district to save an archaeological site discovered recently.

    Tap to read more about the Himalayan Drainage System:

    Drainage System | Part 3

    Kosi River: The Sorrow of Bihar

    • The Kosi is a trans-boundary river which flows through Tibet, Nepal and India.
    • The river crosses into northern Bihar, India where it branches into distributaries before joining the Ganges near Kursela in Katihar district.
    • Its unstable nature has been attributed course changes and the heavy silt it carries during the monsoon season, and flooding in India has extreme effects.
    • It is also known as the “Sorrow of Bihar” as the annual floods affect about 21,000 km2 of fertile agricultural lands thereby disturbing the rural economy.

    Why change its course?

    • Several priceless artefacts have been found at the Guwaradih village in Naugachhia sub-division of Bhagalpur district during the excavation of a mound.
    • These items could be 2,500-years-old and could be of interest for historians if conserved.
    • The historical sites are facing threats from the Kosi floods.
    • The Kosi currently flows around 300-400 metres from the site, while its old course is about two kilometres from the village.

    Threats posed by the move

    • Environmentalists have warned that changing the Kosi’s course could be disastrous for Bihar as seen in 2008.
    • At that time, the river had breached its mud embankments at Kushaha in Nepal.
    • The Kosi frequently changes its course naturally. If its course is artificially changed, it will cause floods and erosion in new areas, leading to massive displacement of people.
    • It then caused extensive damage to life and property downstream in five densely populated districts of northeast Bihar.
    • Some 500 people were killed and four million rendered homeless.
