  • Lowering Emissions by Accelerating Forest Finance (LEAF) Coalition

    At the recently concluded Leaders’ Summit on Climate in April 2021, the Lowering Emissions by Accelerating Forest Finance (LEAF) Coalition was announced.

    LEAF Coalition

    • LEAF Coalition is a collective of the US, UK and Norway governments.
    • It is a public-private effort, thus supported by transnational corporations (TNCs) like Unilever plc, Amazon, Nestle, Airbnb etc.
    • It came up with a $1 billion fund plan that shall be offered to countries committed to arresting the decline of their tropical forests by 2030.
    • The LEAF coalition initiative is a step towards concretizing the aims and objectives of the Reducing Emissions from Deforestation and Forest Degradation (REDD+) mechanism.

    How does this coalition work?

    • The LEAF Coalition can help reverse the trend by providing unprecedented financial support to tropical forest governments implementing forest protection, contributing to green and resilient growth through sustainable investments.
    • It empowers tropical and subtropical forest countries to move more rapidly towards ending deforestation while supporting them in achieving their Nationally Determined Contributions (NDCs) under the Paris Agreement.
    • Reductions in emissions are made across entire countries or large states and provinces (“jurisdictions”) through programs that involve all key stakeholders, including Indigenous peoples and local communities.

    Why is it significant?

    • Financial impetus is crucial as it incentivizes developing countries to capture extensive deforestation and provide livelihood opportunities to forest-dependent populations.
    • The initiative comes at a crucial time when the tropics have lost close to 12.2 million hectares (mha) of tree cover year last year according to global estimates released by Global Forest Watch.
    • Most of these lost forests were located in the developing countries of Latin America, Africa and South Asia.
    • India’s estimated loss in 2020 stands at 20.8-kilo hectares due to forest fires

    What lies next?

    • Implementation of the LEAF Coalition will help pump in fresh rigour among developing countries like India, that are reluctant to recognize the contributions of their forest-dwelling populations in mitigating climate change.
    • With the deadline for proposal submission fast approaching, India needs to act swiftly on a revised strategy.
    • Although India has pledged to carry out its REDD+ commitments, it is impossible to do so without seeking knowledge from its forest-dwelling population.

    Answer this PYQ in the comment box:

    With reference to ‘Forest Carbon Partnership Facility’, which of the following statements is/ are correct?  (CSP 2013)

    1. It is a global partnership of governments, businesses, civil society and indigenous peoples.
    2. It provides financial aid to universities, individual scientists and institutions involved in scientific forestry research to develop eco-friendly and climate adaptation technologies for sustainable forest management.
    3. It assists the countries in their ‘REDD+ (Reducing Emissions from Deforestation and Forest Degradation+)’ efforts by providing them with financial and technical assistance.

    Select the correct answer using the code given below:

    (a) 1 only (b) 2 and 3 only (c) 1 and 3 only (d) 1, 2 and 3

    Back2Basics: REDD+

    • REDD+ is a mechanism developed by Parties to the United Nations Framework Convention on Climate Change (UNFCCC).
    • It creates a financial value for the carbon stored in forests by offering incentives for developing countries to reduce emissions from forested lands and invest in low-carbon paths to sustainable development.
    • Developing countries would receive results-based payments for results-based actions.
    • REDD+ goes beyond simply deforestation and forest degradation and includes the role of conservation, sustainable management of forests and enhancement of forest carbon stocks.
    • It aims to create incentives for communities so that they stop forest degrading practices.

  • What is the ‘Heat Dome’ causing record temperatures in USA?

    A US city has recorded the highest temperatures as high as 46-degree Celsius part due to the historic heatwave that lasted as a result of a phenomenon referred to as a “heat dome”.

    What is a Heat Dome?

    • To understand what causes a heat dome, one should liken the Pacific Ocean to a large swimming pool in which the heater is turned on.
    • Once the heater is on, the portions of the pool close to the heating jets will warm up faster and therefore, the temperature in that area will be higher.
    • In the same way, the western Pacific ocean’s temperatures have increased in the past few decades and are relatively more than the temperature in the eastern Pacific.
    • This strong change in ocean temperature from the west to the east is what a team of scientists believe is the reason for the heat dome.
    • This occurs when the atmosphere traps heat at the surface, which encourages the formation of a heatwave.
    • To compare, the reason that the planet Venus is the hottest in the Solar System is that its thick, dense cloud cover traps the heat at the surface, leading to temperatures as high as 471 degrees Celsius.

    Is this heat wave a result of climate change?

    • It cannot be said for sure if the heatwave is a direct result of global warming.
    • Scientists are usually wary of linking climate change to any contemporary event mainly because of the difficulty in completely ruling out the possibility of the event having been caused by some other reason.
    • Similarly, scientists who have been studying the climate tend to agree that the heat waves occurring today are more likely to be a result of climate change for which humans are responsible.

  • [pib] Glacial Lake Atlas of Ganga River Basin

    The Ministry of Jal Shakti has released the Glacial Lake Atlas of Ganga Basin.

    Glacial Lake Atlas

    • The atlas is based on the inventoried glacial lakes in part of the Ganga River basin from its origin to the foothills of the Himalayas covering a catchment area of 2,47,109 sq. km.
    • The study portion of the Ganga River basin covers part of India and the transboundary region.
    • The Atlas is available on National Hydrology Project or NHP-Bhuvan Portal.
    • It can be used by water resources professionals, researchers, disaster management authorities and other stakeholders for managing the glacial lakes as well as to mitigate the possible adverse impacts of GLOF and climate change.

    Expected utility of the atlas is:

    • The atlas provides a comprehensive and systematic glacial lake database for Ganga River basin with size > 0.25 ha
    • In the context of climate change impact analysis, the atlas can be used as reference data for carrying out change analysis, both with respect to historical and future time periods
    • The atlas also provides authentic database for regular or periodic monitoring changes in spatial extent (expansion/shrinkage), and formation of new lakes
    • The atlas can also be used in conjunction with glacier information for their retreat and climate impact studies.
    • The information on glacial lakes like their type, hydrological, topographical, and associated glaciers are useful in identifying the potential critical glacial lakes and consequent GLOF risk.
    • Central and State Disaster Management Authorities can make use of the atlas for disaster mitigation planning and related program.

  • Species in news: Euphlyctis Kerala

    A new species of skittering frog has been identified from the surroundings of the Thattekkad bird sanctuary.

    Euphlyctis Kerala

    • The new species is named Euphlyctis Kerala in honor of the remarkable biodiversity of the State, which is also known for many endemic species of frogs.
    • The new species is known to be found in the freshwater bodies of the foothills of the Western Ghats, south of the Palakkad Gap.
    • Although multiple skittering frogs have been described from India for almost two centuries (since 1799), the taxonomic mess within this group created a lot of confusion due to “morphological character crypticity”.
    • Members of the genus Euphlyctis (skittering frogs) have their distribution range from Arabian Peninsula, Pakistan, India, Nepal, Sri Lanka, Myanmar, and Thailand.
    • As of now, Kerala is known to have 180 species of frogs and there could be many more new species awaiting formal descriptions.

  • What is Ambergris?

    In the past few weeks, there have been two cases where the Mumbai Police has arrested five persons trying to sell Ambergris or whale vomit.

    What is Ambergris?

    • Ambergris, French for grey amber, is generally referred to as whale vomit.
    • It is a solid waxy substance that floats around the surface of the water body and at times settles on the coast.
    • A sperm whale eats several thousand squid beaks a day.
    • Occasionally, a beak makes it way to the whale’s stomach and into its looping convoluted intestines where it becomes ambergris through a complex process, and may ultimately be excreted by the whale.

    Is it Ambergris valuable?

    • This excretion is so valuable it is referred to as floating gold.
    • As per the latest estimates given by Mumbai Police, 1 kg of ambergris is worth Rs 1 crore in the international market.
    • The reason for its high cost is its use in the perfume market, especially to create fragrances like musk.
    • It is believed to be in high demand in countries like Dubai that have a large perfume market. Ancient Egyptians used it as incense.
    • It is also believed to be used in some traditional medicines.

    Why are the laws on Ambergris?

    • Due to its high value, Ambergris has been a target for smugglers especially in coastal areas.
    • There have been several cases where the coastline of Gujarat has been used for such smuggling.
    • Since the sperm whale is a protected species, hunting of the whale is not allowed.
    • However, smugglers are known to have illegally targeted the fish in order to obtain the valuable Ambergris from its stomach.
    • However, Ambergris is produced only by an estimated one per cent of sperm whales.

  • Places in news: Yellowstone National Park

    A new assessment of climate change in the Yellowstone National Park shows that it has lost a quarter of its annual snowfall.

    Yellowstone National Park

    • Yellowstone NP is an American national park located in the western United States, largely in the northwest corner of Wyoming and extending into Montana and Idaho.
    • Yellowstone was the first national park in the US and is also widely held to be the first national park in the world.
    • The park is known for its wildlife and its many geothermal features, especially Old Faithful geyser, one of its most popular.
    • While it represents many types of biomes, the subalpine forest is the most abundant. It is part of the South Central Rockies forests ecoregion.
    • The area also represents the one point where the three major river basins of the western U.S. converge.
    • The rivers of the Snake-Columbia basin, Green-Colorado basin, and Missouri River Basin all begin as snow on the Continental Divide as it weaves across Yellowstone’s peaks and plateaus.

    Impact of climate change

    • Since 1950, average temperatures in the Greater Yellowstone Area have risen 1.3°C and potentially, more importantly, the region has lost a quarter of its annual snowfall.
    • The loss of snow there has repercussions for a vast range of ecosystems and wildlife, as well as cities and farms downstream that rely on rivers that start in these mountains.
    • It is home to the southernmost range of grizzly bear populations in North America and some of the longest intact wildlife migrations, including the seasonal traverses of elk, pronghorn, mule deer and bison.

  • Compensation for Covid deaths

    The Supreme Court has reserved its verdict seeking compensation of Rs 4 lakh to the kin of those who have died of Covid-19 or related complications.  The Centre has stated that state governments cannot afford to pay this, and had argued in favor of a broader approach including health interventions.

    Provisions for Compensation

    • Last year, the Centre declared Covid-19 as a notified disaster under the Disaster Management Act.
    • Section 12(iii) of the Act says the National Authority shall recommend guidelines for the minimum standards of relief to be provided to persons affected by disaster.
    • It includes “ex gratia assistance on account of loss of life as also assistance on account of damage to houses and for restoration of means of livelihood”.
    • The Centre revises this amount from time to time.

    What is the latest amount?

    • On April 8, 2015, the Disaster Management Division of the Home Ministry wrote to all state governments and attached a revised list of “norms of assistance”.
    • Under “ex gratia payment to families of deceased persons”, it specified: Rs 4 lakh per deceased person including those involved in relief operations or associated in preparedness activities.
    • This is subjected to certification regarding cause of death from appropriate authority.

    So, what about compensation for Covid?

    • Last year the Home Ministry wrote to state governments that the central government has decided to treat it (Covid-19) as a notified disaster for the purpose of providing assistance under SDRF.
    • It attached a partially modified list of items and norms of assistance.
    • It did not specify payment of ex gratia to families of deceased.
    • Some states have decided to pay, but not for all deaths.

    How has the government responded to the petition?

    • The Centre has submitted that ex gratia of Rs 4 lakh is beyond the affordability of state governments.
    • It argued that if Rs 4 lakh is paid to the kin of each, it “may possibly” consume the entire amount of the State Disaster Relief Fund (SDRF).
    • This would leave states with insufficient funds for organizing a response to the pandemic, or to take care of other disasters.
    • The centre argued that the term ex gratia itself means the amount is not based on legal entitlement.

    Way ahead

    • A broader approach, which involves health interventions, social protection, and economic recovery for the affected communities would be a more prudent, responsible, and sustainable approach.

  • Species in news: Pygmy Hogs

    Few captive-bred pygmy hogs, the world’s rarest and smallest wild pigs, were released in the Manas National Park of western Assam under the Pygmy Hog Conservation Programme (PHCP).

    Pygmy Hogs

    • The pygmy hog (Porcula salvania) is a native to alluvial grasslands in the foothills of the Himalayas at elevations of up to 300 m (980 ft).
    • Today, the only known population lives in Assam, India and possibly southern Bhutan.
    • As the population is estimated at less than 250 mature individuals, it is listed as Endangered on the IUCN Red List.
    • It is designated as a Schedule I species in India under the Wildlife Protection Act, 1972, and offences against them invite heavy penalties.

    About Pygmy Hog Conservation Programme (PHCP)

    • The PHCP is a collaboration among Durrell Wildlife Conservation Trust of UK, Assam Forest Department, Wild Pig Specialist Group of IUCN and Union Environment Ministry.
    • It is currently being implemented by NGOs Aaranyak and EcoSystems India.
    • Six hogs — two males and four females — were captured from the Bansbari range of the Manas National Park in 1996 for starting the breeding programme.
    • The reintroduction programme began in 2008 with the Sonai-Rupai Wildlife Sanctuary (35 hogs), Orang National Park (59) and Barnadi Wildlife Sanctuary (22).

  • Retreating Monsoon is a global phenomenon: Study

    Rainfall during retreating monsoon, which parts of South India experience every year, is not a local anomaly and is global in nature and scale, according to a recent study by the University of Sydney.

    What is Retreating Monsoon?

    • In India, retreating monsoon is the withdrawal of south-west monsoon winds from North India.
    • The withdrawal is gradual and takes about three months.
    • With the retreat of the monsoons, the clouds disappear and the sky becomes clear. The day temperature starts falling steeply.
    • Monsoon rains weaken all over India except few southeastern states.
    • It is helpful in Rabi crop cultivation.

    What has the research found?

    • The research has identified regions in the northern hemisphere that receive the bulk of the rainfall during September, October and November and southern hemisphere that receive most of the rainfall from March to August.
    • The discovery that these are part of a global pattern and not one-off occurrences means they can be systematically studied, which will help understand how these communities could be affected by climate change.
    • Peninsular India and parts of South-East Asia are among the eight regions examined in the study.

    Factors affecting the retreat

    • The eight global regions identified by the study that receive most of their rainfall after summer, have several things in common.
    • They lie on the eastern fringes of landmasses and are in close proximity to mountain ranges with modest heights.

    Two predominant factors cause the phenomenon:

    • First, the low mountain range in each region runs from north to south, shielding it from west-bound winds that trigger summer monsoon.
    • After summer, the range aids in the ‘orographic lift’ or rising of east-bound air mass from a lower to higher elevation, forming clouds and resulting in rain.
    • The second factor is atmospheric convection or vertical movement of air.
    • As the earth is heated by the sun, different surfaces absorb different amounts of energy and convection may occur where the surface heats up very rapidly.
    • As the surface warms, it heats the overlying air, which gradually becomes less dense than the surrounding air and begins to rise.
    • This condition is more favorable from September to February because of the role played by sea surface temperature or water temperature.

  • Species in news: Rare Black Softshell Turtle (Nilssonia nigricans)

    A major temple in Assam has signed a MoU with NGOs, the Assam State Zoo-cum-Botanical Garden and the Kamrup district administration for the long-term conservation of the rare freshwater black softshell turtle or the Nilssonia nigricans.

    Two years back, one species from our newscard: Species in news: Hump-backed Mahseer made it into the CSP 2019.  The ‘Puntius Sanctus’ fish in the newscard creates such a vibe yet again.

    A stand-alone species being mentioned in the news for the first time (and that too from Southern India) find their way into the prelims. Make special note here.

     

    Q.Consider the following pairs

    Wildlife Naturally found in
    1. Blue-finned Mahseer Cauvery River
    2. Irrawaddy Dolphin Chambal River
    3. Rusty-spotted Cat Eastern Ghats

    Nilssonia nigricans

    • Until sightings along the Brahmaputra’s drainage in Assam, the black softshell turtle was thought to be “extinct in the wild”.
    • It was confined only to ponds of temples in northeastern India and Bangladesh.
    • The International Union for Conservation of Nature had in 2021 listed the turtle as “critically endangered”.
    • But it does not enjoy legal protection under the Indian Wildlife (Protection) Act of 1972, although it has traditionally been hunted for its meat and cartilage, traded in regional and international markets.
