40% Amazon rainforest unprotected: why is this significant for climate change?

  • 12 Sep 2024

In News

  • Scientists agree that preserving the Amazon rainforest is critical to combating global warming, but new data published recently, indicate huge swathes of the jungles that are vital to the world’s climate remain unprotected.
  • Nearly 40% of the areas of the Amazon rainforest most critical to curbing climate change have not been granted special government protection, as either nature or indigenous reserves, according to an analysis by nonprofit Amazon Conservation.
  • The areas lie in the far southwest of the Amazon in Peru and the far northeast in Brazil, French Guiana, and Suriname, the data show.
  • Those parts of the Amazon have the biggest, densest trees and the most continuous canopy cover. That means these areas hold the most carbon, which would be released into the atmosphere as climate-warming greenhouse gas if the jungle is destroyed by fire or logging.

What satellite data show

  • Amazon Conservation analysed new data from the satellite imaging company Planet that used lasers to get a three-dimensional picture of the forest and combined it with machine-learning models.
  • Only aboveground vegetation was considered, and not underground carbon in roots and soils.
  • Amazon Conservation’s Monitoring of the Andean Amazon Project (MAAP)’s analysis shows that 61% of the peak carbon areas in the Amazon are protected as indigenous reserves or other protected lands, but the rest generally has no official designation.
  • In Brazil, Suriname and French Guiana, only 51% of peak carbon areas are labeled for preservation. Peru protects a higher proportion of its critical areas, but some of the areas that have been left unprotected have been earmarked for logging.

Why the Amazon matters

  • MAAP published an analysis last month showing that the Amazon contained 71.5 billion tonnes of carbon, roughly double the global carbon dioxide emissions for 2022. That analysis showed that the Amazon just barely absorbed more carbon than it released in the decade leading up to 2022, a positive signal for the world’s climate.
  • But that remains an area of intense debate, with other studies showing the Amazon has flipped to become an emissions source.
  • As the effects of anthropogenic climate change become more stark with each passing day, the Amazon becomes one of the most valuable assets for the planet’s health. Scientists say that if the Amazon becomes an emission source instead of a carbon sink — which absorbs carbon from the atmosphere — the impact on the planet may be cataclysmic.

Controversy over Mumbai's salt pans: why do these lands matter?

  • 12 Sep 2024

In News:

Earlier this month, the Centre approved the transfer of 256 acres of salt pan land in Mumbai to the Dharavi Redevelopment Project Pvt Ltd (DRPPL), a joint venture between Adani Realty Group and the Maharashtra government, for building rental housing for slum dwellers.

What are salt pan lands?

  • They comprise parcels of low-lying lands where seawater flows in at certain times, and leaves behind salt and other minerals. Along with Mumbai’s mangroves (also at risk due to development), this ecosystem is instrumental in protecting the city from flooding.
  • According to the Coastal Regulation Zone (CRZ) notification of 2011, the ecologically sensitive salt pans fall under CRZ-1B category, where no economic activity is allowed with the exception of salt extraction and natural gas exploration.
  • In all, 5,378 acres of land in Mumbai have been designated as salt pan lands, approximately nine times the size of the Dharavi slum. About 31% of this land is located in residential and commercial belts, and roughly 480 acres are encroached upon, a 2014 study by the state government found. The same study found that about 1,672 acres of Mumbai’s more than 5,000 acres of salt pan lands are “developable”.
  • Nationally, some 60,000 acres have been demarcated as salt pan lands, spread across Maharashtra, Andhra Pradesh, Tamil Nadu, Odisha, Gujarat, and Karnataka. Andhra Pradesh (20,716 acres) boasts the largest expanse of such land, followed by Tamil Nadu (17,095 acres) and Maharashtra (12,662 acres).

Why are Mumbai’s salt pan lands at risk?

Development Pressure

  • Land Scarcity: Mumbai faces severe land scarcity, with its burgeoning population and high demand for space. Salt pans, being some of the last undeveloped areas, are increasingly targeted for various projects.
  • Development Plans: Multiple state governments have eyed salt pan lands for different uses.

Environmental Significance

  • Flood Prevention: Salt pans are situated in low-lying areas that naturally collect rainwater and tidal flows, helping to mitigate flooding in Mumbai’s eastern suburbs. They act as natural buffers, absorbing excess water during heavy rains and high tides.
  • Historical Context: During the July 2005 deluge, salt pans helped reduce the impact of flooding compared to other areas of Mumbai, highlighting their role in flood management.
  • Ecosystems: Salt pans are home to various species of birds and insects and contribute to local biodiversity. The destruction of these lands could lead to loss of habitat and disruption of local ecosystems.

Risks of Development

  • Flooding Concerns: Environmentalists argue that constructing on these low-lying areas will lead to increased flooding in areas like Vikhroli, Kanjurmarg, and Bhandup. This is because the land’s natural ability to absorb and manage water will be compromised.
  • Quality of Life Issues: Relocating slum-dwellers to these areas raises concerns about their living conditions. Salt pans are prone to flooding, which could undermine the quality of life for new residents. The cost of making these lands habitable, including extensive land filling and waterproofing measures, could negate the benefits of affordable housing.
  • Conflict with Climate Goals: There is a contradiction between Mumbai’s Climate Action Plan, which recognizes climate threats, and the push to develop areas critical for flood management.

Baobab Tree

  • 17 May 2024

Why is it in the News?

A new study has uncovered the origins of baobabs, the tall and uniquely shaped deciduous trees that are famously spotted on the island of Madagascar.

What are Baobab Trees?

  • Baobabs are known for their great heights, with some extending up to 50 metres, and exceptionally long lifespans going up to 2,000 years.
  • In India too, a few baobab trees exist, including one near the Golconda Fort in Andhra Pradesh that is believed to be more than 400 years old.
  • The trees have trunks with large circumferences and thin, spindly branches.
  • In local cultures, the trees are also revered because of the multiple uses their parts have, with the fruits and seeds being edible, the seed oil used for cooking and the bark fibre for clothing.
  • They are also called “upside down” trees because of their tops resembling an uprooted plant turned upside down.

Essential for the ecosystem:

  • Baobab trees are fundamental to the entire dry African savanna ecosystem.
  • They help keep soil conditions humid, aid nutrient recycling, and slow soil erosion with their massive root systems.
  • As a succulent, the tree absorbs and stores water from the rainy season in its massive trunk, producing a nutrient-dense fruit in the dry season, which can grow up to a foot long.
    • The fruit contains tartaric acid and Vitamin C, serving as a vital nutrient and food source for many species.
  • They are also an essential source of water and shelter for hundreds of animals, including birds, lizards, monkeys, and even elephants – which can eat their bark for moisture when there is no water nearby.

In human culture:

  • For humans, the baobab’s fruit pulp can be eaten, soaked in water to make a refreshing drink, preserved into a jam, or roasted and ground to make a coffee-like substance.
  • The bark can be pounded to make everything from rope, mats, and baskets to paper and cloth.
  • Leaves are also used, they can be boiled and eaten, or glue can be made from their flower’s pollen.

What Did the Study Find?

  • The study highlighted the threats facing baobab trees and examined their genetic makeup.
    • It reported that three Madagascar species of baobab trees are threatened with extinction, according to the IUCN Red List of Threatened Species.
  • The study identified various threats, including residential and commercial development and livestock farming, which require land clearing.
    • However, even species not currently endangered show declining populations, suggesting that more rigorous conservation strategies are needed to ensure their long-term survival.
    • This necessitates a detailed understanding of the baobabs' genetics.
  • Genomic sequencing revealed a consensus on the monophyly of the Malagasy lineage from Madagascar.
    • According to DNA studies, baobab trees first arose in Madagascar 21 million years ago, with their seeds later carried by ocean currents to Australia and mainland Africa, where they evolved into distinct species.
  • The study also warned that climate change poses severe threats to Adansonia suarezensis from Madagascar, predicting its possible extinction by 2080.
    • Due to their unique ecological roles and low genetic diversity, these species are likely to have reduced resilience to environmental changes and habitat fragmentation.

  • 01 Apr 2024

Why is it in the News?

Recently, Japan announced that its experts have engaged in discussions with their Chinese counterparts to address Beijing's concerns regarding the release of treated radioactive wastewater from the damaged Fukushima Daiichi nuclear power plant into the sea.

What is the Fukushima Water Issue?

  • In 2021, the Japanese government unveiled plans to gradually discharge over one million tonnes of contaminated water from the Fukushima nuclear plant into the ocean over the next three decades.
  • The contaminated water is a residual product of the devastating 2011 earthquake and tsunami that incapacitated the Fukushima Daiichi nuclear power plant, resulting in the release of radioactive materials.
  • After more than ten years of storing this wastewater, Japan asserts that they are facing storage space limitations and contends that the treated water is now safe for release.

Concerns Surrounding the Fukushima Water Discharge:

  • Tritium and Carbon-14: The water from Fukushima undergoes filtration via the Advanced Liquid Processing System (ALPS), effectively reducing most radioactive contaminants to acceptable safety levels, except tritium and carbon-14.
    • While both emit low levels of radiation, consumption in large quantities could potentially pose risks.
  • Insufficient Research: Scientists emphasize the need for further investigation into the potential impact of the water discharge on the ocean bed and marine ecosystems.
  • The Pacific Islands Forum regional group has labeled the proposed plan as "another significant nuclear contamination disaster," citing ongoing challenges faced by its member nations due to past US nuclear testing.

Pacific Islands Forum (PIF):

  • The Pacific Islands Forum (PIF) is an inter-governmental organization that aims to enhance cooperation among countries and territories of Oceania, including the formation of a trade bloc and regional peacekeeping operations.
  • It was founded in 1971 as the South Pacific Forum (SPF), and changed its name in 1999 to "Pacific Islands Forum", to be more inclusive of the Forum's Oceania-spanning membership of both north and south Pacific island countries, including Australia.
  • It is a United Nations General Assembly observer.
  • The PIF secretariat is located in Suva, the capital of Fiji.

Nuclear Incidents:

  • A nuclear and radiation incident denotes an occurrence that has resulted in significant repercussions for individuals, the environment, or the facility involved.
  • These may entail fatal consequences for individuals, substantial releases of radioactivity into the environment, or reactor core meltdowns.

Pusa Basmati Rice

  • 21 Mar 2024

Why is it in the News?

Even as basmati rice exports from the country are poised to scale a new high, scientists at the Indian Agricultural Research Institute (IARI) have red-flagged the “illegal” cultivation of its blockbuster varieties in Pakistan.

Unauthorized Cultivation and Export of Pusa Basmati Rice Varieties in Pakistan:

  • Despite being officially registered and protected Indian varieties, several IARI-bred Basmati rice varieties, such as Pusa Basmati 1121, Pusa Basmati-6, and Pusa Basmati 1509, are being illegally cultivated and marketed in Pakistan.
    • Recent YouTube videos even feature newer IARI varieties like Pusa Basmati-1847, PB-1885, and PB-1886, released in late 2021.
  • Pakistan's unauthorized Basmati exports have been substantial, with 7.58 lt ($694.55 million) in 2021-22 and 5.95 lt ($650.42 million) in 2022-23 (July-June).
    • This growth is partly due to the depreciation of the Pakistani rupee, allowing the country to offer lower export prices than India.
  • The proliferation of these protected varieties in Pakistan can be attributed to the ease of seed multiplication.
    • With just a small quantity of seeds, large-scale cultivation can be established within two years of the variety's release in India.
    • This unauthorized cultivation not only undermines India's intellectual property rights but also impacts the competitiveness of India's Basmati rice exports in the global market.

What is the Basmati Crop Improvement Program?

  • The Basmati Crop Improvement Program focuses on refining the unique qualities of Basmati rice, such as its distinct grain characteristics, cooking properties, and pleasing aroma.
  • IARI has played a crucial role in the genetic enhancement, leading to the development of high-yielding, semi-dwarf, and photo-insensitive Basmati varieties like Pusa Basmati 1.
  • These improvements have significantly reduced the crop duration from 160 to 120 days and increased productivity from 2.5 to 6-8 tons per hectare.
  • As a result, these advanced Basmati varieties account for approximately 90% of India's projected $5.5 billion exports in 2023-24.
    • This achievement contributes to substantial foreign exchange earnings and economic growth for the country.

Key Features of IARI-Developed Basmati Rice Varieties:

  • IARI has cultivated various Basmati rice varieties with distinct characteristics, including:
  • Pusa Basmati 1121: Known as the world's longest Basmati rice, it matures in 145 days with an average yield of 45 q/ha.
  • Pusa Basmati 1509: Derived from Pusa 1121 x Pusa 1301, this variety addresses Pusa Basmati 1121's weaknesses, matures in 115 days, and yields 5 tons/ha.
  • Improved Pusa Basmati 1 (Pusa 1460): This variety, the first product of molecular breeding in Indian rice, is an enhanced Pusa Basmati 1 with bacterial leaf blight resistance.
  • Pusa Basmati 6 (Pusa 1401): Offering superior grain quality, this variety improves upon Pusa 1121's yielding ability, agronomy, and cooking quality.
  • Pusa RH10: The world's first superfine grain aromatic rice hybrid, it was released in 2001 for commercial cultivation in specific irrigated ecosystems.

Registration and Cultivation Areas of Pusa Basmati Rice in India:

  • All Pusa Basmati rice varieties are officially recognized under the Seeds Act 1966 and can be cultivated within the designated Geographical Indication (GI) area of Basmati rice in India, encompassing seven northern states.
  • These varieties are further registered under the Protection of Plant Varieties and Farmers' Rights Act 2001, which permits only Indian farmers to sow, save, re-sow, exchange, or share the seeds of protected/registered varieties.

  • Extensive Marine Heatwaves: Nearly one-third of the global ocean experienced a marine heatwave on an average day in 2023.
    • Over 90% of the ocean had faced heatwave conditions at some point during the year, negatively impacting ecosystems and food systems.
  • Unprecedented Glacier Ice Loss: Preliminary data reveals the largest loss of ice since 1950 for the global set of reference glaciers, driven by extreme melt in western North America and Europe.
  • Surge in Renewable Energy Capacity: Renewable capacity additions in 2023 increased by almost 50% from 2022, totaling 510 gigawatts (GW) and marking the highest rate in the past two decades.

Equity Issues in IPCC Reports

  • 18 Mar 2024

Why is it in the News?

In a study published recently, researchers analyzed more than 500 future emissions scenarios the UN Intergovernmental Panel on Climate Change (IPCC) assessed in its latest reports.

About the Intergovernmental Panel on Climate Change (IPCC):

  • The IPCC was created in 1988 by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP).
  • It is the leading international body for the assessment of climate change.
  • It is a key source of scientific information and technical guidance to the United Nations Framework Convention on Climate Change (UNFCCC) and the Paris Agreement.
  • The IPCC provides governments with scientific information for use in developing climate policies.
  • The IPCC currently has 195 members.
  • The IPCC does not undertake new research. Instead, it synthesizes published and peer-reviewed literature to develop a comprehensive assessment of scientific understanding.
    • These assessments are published in IPCC reports.
    • They are subject to multiple drafting and review processes to promote an objective, comprehensive, and transparent assessment of current knowledge.
  • The IPCC’s work is guided by principles and procedures that govern all main activities of the organization.
  • IPCC member governments and observer organizations nominate experts and the IPCC's scientific governing body, the IPCC Bureau, selects authors and editors with expertise in a range of scientific, technical, and socio-economic fields.

What are IPCC Assessment Reports?

  • Typically, IPCC reports comprise three Working Group reports:
    • One on physical science
    • One on climate adaptation, and
    • One on mitigation action.
  • One synthesis report consolidates findings from the three Working Group reports.
  • Then there are thematic special reports.
  • Each report assesses climate-related scientific literature to capture the state of scientific, technical, and socio-economic knowledge on climate change.
  • The IPCC is currently in its Seventh Assessment cycle (AR7).

How Does it Assess Future Scenarios?

  • The IPCC uses ‘modelled pathways’ to estimate what it will take to limit the warming of the earth’s surface.
  • These pathways are drawn using Integrated Assessment Models (IAMs) that describe human and earth systems.
  • IAMs are complex models that examine possible futures of the energy and climate systems and economies.
  • Its macroeconomic models can point to future growth levels in terms of GDP;
    • Its energy models can project future consumption
    • Vegetation models can examine land-use changes; and
    • Earth-system models use the laws of physics to understand how climate evolves.
  • With such integration across disciplines, IAMs are meant to provide policy-relevant guidelines on climate action.
  • However, these models also have shortcomings. They prioritize least-cost assessments — for example, the absolute cost of setting up a solar plant or undertaking afforestation in India is lower than in the U.S.
  • However, experts have said they could exercise the option of enabling countries to equitably share the burden of action, where the richest undertake more drastic mitigation action more immediately.

About the Latest Study:

  • Conducted by a team of specialists from Bengaluru and Chennai, the study scrutinized 556 scenarios outlined in the IPCC's AR6 report.
  • Their findings indicate that by 2050, per-capita GDP in Sub-Saharan Africa, South Asia, West Asia, and other parts of Asia will remain below the global average.
  • Collectively, these regions account for 60% of the global population.
  • Additionally, the study highlighted disparities in the consumption of goods and services, as well as energy and fossil fuel consumption, between the Global North and the Global South.

Why Does Equity Matter?

  • Equity is crucial in climate action as per the UNFCCC, which mandates developed nations to lead in combating climate change.
  • However, current modeling approaches often overlook equity, burdening poorer nations disproportionately.
  • Researchers highlight the need for modeling techniques that prioritize climate justice and equitable distribution of responsibilities.
  • They argue that mitigation pathways should ensure developed regions accelerate towards net negative emissions and allocate carbon budgets to less developed regions.
  • Addressing this gap requires a paradigm shift in scenario building, emphasizing both equity and environmental sustainability.
  • This approach is vital for fostering global cooperation and achieving meaningful climate action.

Kerala declares man-animal conflict a state-specific disaster

  • 08 Mar 2024

Why is it in the News?

Amid repeated deaths from animal attacks and rising anger over them, Kerala recently declared man-animal conflict as a state-specific disaster, becoming the first state in the country to do so.

What is Man-animal Conflict?

  • Man-animal conflict refers to the interaction between wild animals and humans, resulting in adverse outcomes for both people and wildlife, as well as their habitats.
  • Escalating Conflict: In states across India, human-wildlife conflict has intensified, leading to a significant rise in human casualties.
    • For instance, in Maharashtra, the conflict resulted in 86  in 2021 and 105 deaths in 2022, marking a sharp increase compared to previous decades.

Causes:

  • Factors contributing to this conflict include the encroachment of grodeathswing human and animal populations into each other's territories, habitat fragmentation due to legal and illegal land use changes, alterations in cropping patterns attracting wildlife to agriculture, and habitat destruction from invasive alien species.
    • Despite having over 700 protected areas, a substantial portion of elephant, lion, and tiger ranges lie outside these protected zones, exacerbating the conflict.

Ecologist Perspective:

  • Ecologist Madhav Gadgil highlights that the Wildlife Protection Act of 1972 has inadvertently facilitated an environment where wild animals can invade human habitats with impunity.
    • He cites the optimal foraging theory in ecology, which underscores animals' efforts to maximize nutrient intake while minimizing time, effort, and risks.

Solutions:

  • Addressing the issue requires robust enforcement and pragmatic policies to mitigate conflict incidences.
    • Engaging local communities, as suggested by the Future for All Report 2021 (by WWF and UNEP), fosters coexistence between humans and wildlife, acknowledging that complete elimination of conflicts is impractical.
    • Additionally, awareness campaigns aimed at educating the public about man-animal conflict and skill development initiatives for communities living near forests can alleviate pressures on agricultural and forest lands.

Kerala's Decision to Declare Man-Animal Conflict as a State-Specific Disaster:

  • Implications of the Decision: Currently, the management of man-animal conflict falls under the jurisdiction of the forest department, operating in accordance with the Wildlife Protection Act.
    • By designating man-animal conflict as a state-specific disaster, the responsibility for addressing it shifts to the state disaster management authority, empowered by the Disaster Management Act, enabling swifter and more decisive action.
  • Rationale for the Decision: Instances of loss of life due to man-animal conflict have prompted calls to tranquilize, capture, or eliminate the responsible animals.
    • Presently, the chief wildlife warden, holding the sole authority in the state, makes decisions regarding wild animals causing disturbances in human settlements.
    • Past decisions to tranquilize aggressive animals, like wild elephants, have faced legal challenges.
  • Under the disaster management authority, actions can be taken that supersede other regulations, including those outlined in the Wildlife Protection Act.
  • According to the Disaster Management Act, except for the Supreme Court or a High Court, no court has jurisdiction to entertain suits or proceedings regarding actions taken by relevant authorities in line with the Act.
  • Additionally, the Act stipulates that its provisions hold precedence over any other law during the specific period of a declared disaster.

Kerala's Success in Managing Man-Animal Conflict:

  • Kerala, with approximately 5,700 wild elephants in 2017, comprising 19% of the nationwide population of 30,000, witnessed a significantly lower incidence of human fatalities caused by elephants, accounting for only 81 (4%) of the 2,036 deaths recorded in India between 2018 and 2021.
  • Factors Contributing to Kerala's Effective Management of Man-Animal Conflict:
  • Maintenance of Unchanged Wilderness Boundaries: Kerala has largely preserved the boundaries between wilderness and civilization in recent years, contributing to the mitigation of man-animal conflicts.
  • Evolution of Agricultural Practices: Changes in agricultural practices, such as the cultivation of crops like coffee, pepper, and tea, which hold less appeal for elephants, have helped reduce conflicts between humans and elephants.
  • Unique Elephant Characteristics: Individual elephants are identified and named based on their distinct characteristics, such as Kabali, an elephant residing in the Athirapally jungle in Thrissur district, known for its tendency to attack or chase automobiles.
  • These factors collectively contribute to Kerala's successful management of man-animal conflict, resulting in relatively fewer human fatalities caused by elephants compared to other regions in India.

Trees in Corbett fell prey to greedy nexus, says Supreme Court

  • 07 Mar 2024

Why is it in the News?

The Supreme Court on Wednesday condemned the illegal felling of over 6,000 trees to construct buildings, ostensibly for “eco-tourism” at the Jim Corbett National Park in Uttarakhand, as a “classic case” of nexus between politicians and officials working to ransack the environment for short-term commercial ends.

News Summary:

  • In 2023, a series of applications brought attention to the creation of alleged illegal buildings and encroachment on water bodies, prompting court intervention.
  • Petitioners highlighted violations of environmental norms and encroachment into core wildlife habitats.
  • Evidence presented during proceedings revealed unauthorized constructions within the national park, including concrete and iron enclosures purportedly intended for a 'safari' experience.
  • Moreover, it was disclosed that over 6,000 trees had been felled in the national park under the pretext of safari development.

Supreme Court’s Observations:

  • The Court has raised concerns regarding the necessity of developing facilities within natural forest environments, particularly in areas designated for the protection of endangered species like tigers.
  • Directing the Government to establish a committee, the Supreme Court seeks recommendations on whether tiger safaris should be permitted in buffer or fringe areas and what guidelines should govern their establishment if allowed.
  • Additionally, the Court has strongly criticized the illegal constructions and extensive tree felling in Uttarakhand's Corbett National Park.

What are the Core and Buffer Areas in Tiger Reserves?

  • As per the Wild Life (Protection) Amendment Act of 2006, a Tiger Reserve comprises core or critical habitat and a buffer zone surrounding it.
  • Core areas hold the legal status of a National Park or a Sanctuary.
  • Buffer zones consist of a mix of forest and non-forest land, managed as a multiple-use area.
  • The buffer area acts as a protective barrier, absorbing the impact of poaching pressure on tiger and other wildlife populations.

About Jim Corbett National Park:

  • Location: Situated in the Nainital district of Uttarakhand, Jim Corbett National Park is renowned for its rich biodiversity.

Key Facts:

  • Established in 1935, it is India’s oldest national park.
  • Initially named Hailey National Park after its founder Sir Malcolm Hailey, it was renamed Corbett National Park in 1956 to honor Jim Corbett's contributions to wildlife preservation in India.
  • Corbett National Park boasts the highest population of tigers in India, highlighting its importance for tiger conservation efforts.
  • Flora: Dominated by Sal, Semal, Kharpat, Sissoo, Khair, Dhak, Khingan, Bakli, Bel, Ber, Bamboo, Khingam, Jamun, Kanju, Rohini, and Pula trees.
    • Sal, Khair, and Sissoo are prominently featured throughout the park.
  • Fauna: Home to diverse wildlife including Tiger, Leopard, Elephant, Chital Deer, Sambar Deer, Hogg Deer, Barking Deer, Wild Boar, Langur, Wild pig, Rhesus Monkey, Jackal, Rabbit, Yellow Throated Martin, and Otters.
    • Various reptiles such as Crocodile, Gharial, King Cobra, Common Krait, Cobra, Russell's Viper, Rock Python, and Monitor Lizard inhabit the park.
  • The Kosi River feeds the eastern periphery of Corbett National Park.
  • The Ramganga River (West) and its tributaries Sonanadi, Palain, and Mandal serve as significant hydrological resources for the park.

Exclusive-World on brink of fourth mass coral reef bleaching event- NOAA

  • 06 Mar 2024

Why is it in the News?

The world stands on the brink of witnessing its fourth mass coral bleaching event, a phenomenon that threatens to hit vast expanses of tropical reefs, including significant portions of Australia's iconic Great Barrier Reef.

Key Findings from the National Oceanic and Atmospheric Administration (NOAA):

  • Impending Fourth Mass Coral Bleaching Event: The world is on the brink of a fourth mass coral bleaching event, following those in 1998, 2010, and 2014.
    • To classify as global, widespread bleaching must occur across three ocean basins: the Atlantic, Pacific, and Indian.
  • Impact of Previous Events: The last global mass coral bleaching event occurred from 2014 to 2017, resulting in the loss of nearly a third of the Great Barrier Reef's corals.
    • Preliminary data indicates that approximately 15% of the world's reefs experienced significant coral die-offs during this event.
  • Current Situation: This year is witnessing even more severe bleaching events, with the Caribbean experiencing its worst coral bleaching on record following the Northern Hemisphere summer last year.
  • Link to Climate Phenomena: Coral bleaching is often associated with the naturally occurring El Niño climate phenomenon, which leads to warmer ocean waters.
  • Climate Change Impact: The world recently experienced its first 12-month period with an average temperature exceeding 1.5 degrees Celsius (2.7 degrees Fahrenheit) above pre-industrial levels.
    • A temperature rise of 1.5°C is considered the tipping point for mass coral die-offs, with scientists estimating that 90% of the world's corals could be lost as a result.

About the Corals and Coral Reefs:

  • Corals: Corals are animals known as polyps, which engage in a symbiotic relationship with tiny algae called zooxanthellae.
    • These algae provide corals with food and oxygen, while corals offer them a safe habitat.
  •  Coral Reefs: Coral reefs are limestone structures formed by thousands of tiny coral animals and are predominantly found in tropical climates.

Coral Bleaching and Its Concerns:

  • Coral bleaching occurs when corals are exposed to stressful conditions like high temperatures, pollution, or changes in water chemistry, leading them to expel the zooxanthellae.
    • Without these algae, corals lose their color and turn white, hence the term 'bleaching,' and cannot survive for long in this state.
  • Recovery Potential: Despite its severity, coral bleaching doesn't necessarily mean the end of the reef; timely removal of stressors can facilitate the return of zooxanthellae and coral recovery.
  • Ecological Importance: Coral reefs serve as habitats and food sources for numerous fish and marine species.
    • They also offer coastal protection from erosion and storms and play a critical role in regulating the Earth's climate by absorbing and storing carbon dioxide.
  • Cultural and Aesthetic Value: Beyond their ecological functions, coral reefs represent stunning biodiversity and natural beauty, making their loss a tragic prospect for future generations.
  • Impacts: When coral reefs suffer, so do the ecosystems and communities reliant on them, underscoring the far-reaching consequences of coral degradation.

 

Google-backed satellite to track global oil industry methane emissions

  • 06 Mar 2024

Why is it in the News?

MethaneSAT — a satellite which will track and measure methane emissions at a global scale — was launched aboard a SpaceX Falcon9 rocket from California recently.

What is MethaneSAT?

  • MethaneSAT will orbit the Earth 15 times a day, monitoring the oil and gas sector.
  • It will create a large amount of data, which will tell “how much methane is coming from where, who’s responsible, and are those emissions going up or down over time”.
  • The data collected by MethaneSAT will be made public for free in near real-time.
  • This will allow stakeholders and regulators to take action to reduce methane emissions.

Institutions involved in the development:

  • The entity behind MethaneSAT is the Environmental Defense Fund (EDF) — a US-based nonprofit environmental advocacy group.
  • To develop the satellite, EDF partnered with Harvard University, the Smithsonian Astrophysical Observatory, and the New Zealand Space Agency.

Features of MethaneSAT:

  • Historically, tracking the source of methane emissions and measuring them has been quite challenging.
    • ?While some satellites can provide high-resolution data, they can only scan specific, pre-targeted sites.
    • Others can examine larger areas and detect large emitting events, but cannot scan “smaller sources that account for the majority of emissions in many, if not most, regions,” the EDF statement added.
  • Due to this discrepancy, according to an International Energy Agency (IEA) report, global methane emissions are about 70 per cent higher than levels reported by national governments.
  • MethaneSAT is expected to fix the issue.
  • Equipped with a high-resolution infrared sensor and a spectrometer, the satellite will fill critical data gaps.
  • It can track differences in methane concentrations as small as three parts per billion in the atmosphere, which enables it to pick up smaller emissions sources than the previous satellites.
  • MethaneSAT also has a wide-camera view — of about 200 km by 200 km — allowing it to identify larger emitters so-called “super emitters”.

Significance of MethaneSAT:

  • Advancing the Goals of the Global Methane Pledge 2021: The Global Methane Pledge, signed by over 150 countries in 2021, aims to reduce collective methane emissions by at least 30% from 2020 levels by 2030.
    • During the previous year's COP, over 50 companies pledged to significantly reduce methane emissions and routine flaring.
    • MethaneSAT will play a crucial role in helping these entities achieve their targets.
  • Enhancing Transparency: The satellite will usher in a new era of transparency by providing publicly available data accessible to anyone worldwide.
  • This data will enable monitoring of methane commitments made by governments and corporations, promoting accountability and transparency in emission reduction efforts."

Why Do We Need to Track and Measure Methane Emission?

  • Methane is an invisible but strong greenhouse gas, and the second largest contributor to global warming after carbon dioxide, responsible for 30 percent of global heating since the Industrial Revolution.
  • According to the United Nations Environment Programme, over a period of 20 years, methane is 80 times more potent at warming than carbon dioxide.
  • The gas also contributes to the formation of ground-level ozone — a colorless and highly irritating gas that forms just above the Earth’s surface.
    • According to a 2022 report, exposure to ground-level ozone could be contributing to one million premature deaths every year.
  • Therefore, it is crucial to cut methane emissions and the main culprit, fossil fuel operations, which account for about 40 percent of all human-caused methane emissions.
  • The objective of MethaneSAT is to help achieve this goal.

Carbon Capture and How it Can Help Save the Planet

  • 05 Mar 2024

Why is it in the News?

Germany has recently declared its approval for carbon capture and offshore storage for specific industrial sectors.

What is Carbon Capture and Storage?

  • CCS refers to a host of different technologies that capture CO2 emissions from large point sources like refineries or power plants and trap them beneath the Earth.
  • Notably, CCS is different from carbon dioxide removal (CDR), where CO2 is removed from the atmosphere.
  • CCS involves three different techniques of capturing carbon, including: Post-combustion, Pre-combustion, and Oxyfuel combustion.
    • In post-combustion, CO2 is removed after the fossil fuel has been burnt. By using a chemical solvent, CO2 is separated from the exhaust or ‘flue’ gasses and then captured.
    • Pre-combustion involves removing CO2 before burning the fossil fuel. “First, the fossil fuel is partially burned in a ‘gasifier’ to form synthetic gas. CO2 can be captured from this relatively pure exhaust stream,” according to a report by the British Geological Survey. The method also generates hydrogen, which is separated and can be used as fuel.
    • In oxyfuel combustion, the fossil fuel is burnt with almost pure oxygen, which produces CO2 and water vapor. The water is condensed through cooling and CO2 is separated and captured. Out of the three methods, oxyfuel combustion is the most efficient but the oxygen burning process needs a lot of energy.
  • Post-combustion and oxyfuel combustion equipment can be retro-fitted in existing plants that were originally built without them. Pre-combustion equipment, however, needs “larger modifications to the operation of the facility and are therefore more suitable to new plants.
  • After capture, CO2 is compressed into a liquid state and transported to suitable storage sites.
    • Although CO2 can be transported through ship, rail, or road tanker, pipeline is the cheapest and most reliable method.

Can Carbon Capture Help Save the world?

  • Operational CCS projects generally claim to be 90 percent efficient, meaning they can capture 90 per cent of carbon and store it.
  • Studies, however, have shown that a number of these projects are not as efficient as they claim to be.
    • For example, a 2022 study by the Institute for Energy Economics and Financial Analysis (IEEFA) found most of the 13 flagship CCS projects worldwide that it analyzed have either underperformed or failed entirely.
  • Moreover, CCS technologies are quite expensive.
    • When CCS is attached to coal and gas power stations it is likely to be at least six times more expensive than electricity generated from wind power backed by battery storage.
    • It is far cheaper and more efficient to avoid CO2 emissions in the first place.
  • There are also only a few operational CCS projects across the world even though the technology has been pushed for decades.
  • According to the International Energy Agency (IEA), there were 40 operational CCS projects in 2023, which captured more than 45 metric tonnes (Mt) of CO2 annually.
  • To ensure the planet doesn’t breach the 1.5 degree Celsius temperature increase limit, it would take an “inconceivable” amount of carbon capture “if oil and natural gas consumption were to evolve as projected under today’s policy settings.
  • It added that the electricity required to capture that level of carbon as of 2050 would be more than the entire planet’s use of electricity in 2022.
  • Therefore, there couldn’t be an overreliance on carbon capture as a solution to tackle climate change.

Doomsday Glacier has lost 50 billion tons of ice, melting began 80 years ago

  • 01 Mar 2024

Why is it in the News?

Antarctica's Doomsday Glacier, the world's widest glacier, has lost over 50 billion tons of ice and the melting rate is on the rise as the continent gets warmer.

What is Doomsday Glacier?

  • The Thwaites Glacier (also known as Doomsday Glacier), a massive and world’s widest glacier is located in West Antarctica.
  • The Doomsday nickname reflects the potential for catastrophic flooding if the glacier were to collapse completely.
  • Scientists are particularly concerned about Thwaites Glacier because of its size and location.
    • If it were to collapse or significantly retreat, it could lead to a more rapid flow of ice from the interior of West Antarctica into the ocean, contributing to rising sea levels.
    • The collapse could lead to a 65 cm rise in global sea level.
  • The ice loss in the region has been observed to be accelerating since the 1970s, however, so far it remained unclear as to when this retreat began.
  • The significant glacial retreat began in the 1940s and the findings coincide with previous work that studied retreat on Pine Island Glacier and found glacial retreat began in the ‘40s as well.
  • This change is not random nor specific to one glacier but It is part of a larger context of a changing climate.

Why Did the Melting Begin?

  • The meeting was kicked off by an extreme El Nino climate pattern that warmed the west Antarctic, and since then the glacier has not been able to recover from the damage.
    • It is significant that El Niño only lasted a couple of years, but the two glaciers, Thwaites and Pine Island remain in significant retreat.
    • Once the system is kicked out of balance, the retreat is ongoing.
  • The Doomsday Glacier's melting remains one of the most crucial events triggered and accelerated by climate change and could lead to the submergence of several coastal regions of the world.
