Montreux Record, AQI & COP28
The 6 Biotic Species Interactions (+, -, 0): Mutualism to Amensalism
A perennial UPSC Prelims matching question testing (+/+), (+/0), (-/0), and (+/-) relationships.
- 1. Mutualism (+ / +): Both species benefit and are often obligatory (e.g., Lichens = Algae [food] + Fungi [shelter/water]; Mycorrhiza = Fungi + Plant roots; Coral polyps + Zooxanthellae; Fig tree + Wasp).
- 2. Commensalism (+ / 0): One benefits, the other is unaffected (e.g., Epiphytes/Orchids growing on mango branches; Barnacles riding on whales; Cattle Egret & grazing cattle; Suckerfish/Remora on sharks).
- 3. Amensalism (- / 0): One is harmed/inhibited while the other is completely unaffected! Classic examples: Penicillium fungus secreting penicillin that kills bacteria; Black Walnut tree secreting Juglone toxin (Allelopathy) that prevents herbs from growing under its canopy.
- 4. Predation (+ / -) & Parasitism (+ / -): One benefits, the other is harmed (e.g., Cuscuta/Amarbel dodder plant, ticks, tapeworms, Koel brood parasitism).
- 5. Competition (- / -): Both species suffer reduced fitness competing for the same limiting resource (Gause’s Competitive Exclusion Principle).
⚡ PRELIMS TRAP: In Amensalism (- / 0), the inhibiting species gains ZERO benefit from harming its neighbour—unlike Predation/Parasitism (+ / -)!
Habitat vs. Ecological Niche (Gause Principle) & Ecotone Edge Species
Why two species can share the same Habitat but never the exact same Ecological Niche.
- Habitat (Address) vs Ecological Niche (Profession — Joseph Grinnell, 1917): Habitat is the physical place where many species live together. Niche is the unique functional role, trophic position, and micro-environmental requirement of a single species.
- Gause’s Competitive Exclusion Principle: No two species can occupy the exact same Ecological Niche in the same habitat indefinitely—the superior competitor will drive the inferior one to extinction or niche shift (Resource Partitioning).
- Ecotone & Edge Effect: An Ecotone is a zone of tension/junction between two biomes (e.g., Mangroves between land & sea, Estuary between river & ocean, Grassland between forest & desert). The increased variety and density of species at this boundary is the Edge Effect (birds are particularly abundant in terrestrial ecotones!).
⚡ PRELIMS TRAP: A wider Ecotone with a well-developed Edge Effect can harbor species that are completely absent from either of the two adjoining ecosystems (called Edge Species)!
Upright, Inverted & Spindle Pyramids of Numbers, Biomass & Energy
When is a Pyramid of Numbers spindle-shaped vs inverted, and why Energy is never inverted.
- 1. Pyramid of Numbers (Can be Upright, Inverted, or Spindle-shaped!):
• Upright: Grassland & Pond ecosystems (Grass → Grasshopper → Frog → Snake).
• Spindle-Shaped: A single large Forest Tree supporting many herbivorous birds, which in turn support fewer predatory hawks/eagles.
• Inverted: A Parasitic Food Chain on a single tree (1 Tree → 100s of fruit-eating birds → 1,000s of lice/bugs → millions of hyperparasite bacteria/protozoa). - 2. Pyramid of Biomass (Standing Crop = Dry Weight per unit area):
• Upright: All terrestrial ecosystems (Forests, Grasslands).
• Inverted: Aquatic/Marine Ecosystems because microscopic phytoplankton have a tiny standing crop biomass at any single moment compared to the long-lived large fish and whales feeding on them. - 3. Pyramid of Energy (Lindeman’s 10% Law): ALWAYS UPRIGHT without exception because 90% of energy is lost as metabolic heat at every trophic transfer.
⚡ PRELIMS TRAP: Saprophytes / Decomposers (fungi & bacteria) are NOT given any place in traditional ecological pyramids even though they play a vital role in nutrient recycling!
Bioaccumulation vs. Biomagnification & The 4 Conditions for a Pollutant to Magnify
Why water-soluble toxins get excreted while fat-soluble POPs explode up the food chain.
- Bioaccumulation (Within 1 Organism): The gradual build-up of a pollutant inside a single organism over time (entry from environment into the first organism in a food chain).
- Biomagnification / Bioamplification (Across Trophic Levels): The progressive increase in concentration of a pollutant from one link in a food chain to the next higher trophic level.
- 4 Mandatory Conditions for Biomagnification (UPSC 2015/2021): The pollutant MUST be:
1. Long-lived (Persistent) in the environment.
2. Mobile (able to be taken up by organisms).
3. Soluble in FATS (Lipophilic)—if it is water-soluble, the organism simply excretes it in urine!
4. Biologically active (e.g., DDT, Endosulfan, Methylmercury, Polychlorinated Biphenyls [PCBs]).
⚡ PRELIMS TRAP: If a pollutant is water-soluble, it will NOT biomagnify! Only fat-soluble (lipophilic) persistent pollutants accumulate in adipose tissues and biomagnify.
Gaseous vs. Sedimentary Nutrient Cycles & Nitrogen Fixation Bacteria
Distinguishing Carbon/Nitrogen cycles from Phosphorus/Sulphur cycles and N-fixing microbes.
- Gaseous Cycles (Reservoir = Atmosphere / Hydrosphere): Water, Carbon, and Nitrogen cycles. They are fast and considered "perfect" cycles because nutrients are rapidly replaced.
- Sedimentary Cycles (Reservoir = Earth’s Crust / Rocks): Phosphorus, Sulphur, Calcium, and Magnesium cycles. Weathering of rocks releases them slowly.
- Nitrogen Cycle Bacteria (High-Frequency UPSC Question):
• Free-Living N2 Fixers: Azotobacter, Clostridium, Rhodospirillum + Cyanobacteria (Anabaena, Nostoc, Spirulina).
• Symbiotic N2 Fixers: Rhizobium (in leguminous root nodules) & Frankia (in non-leguminous Alnus/Casuarina).
• Nitrification (Ammonia → Nitrite → Nitrate): Nitrosomonas & Nitrococcus (NH3 → NO2^-), then Nitrobacter (NO2^- → NO3^-).
• Denitrification (Nitrate → N2 gas): Pseudomonas & Thiobacillus.
⚡ PRELIMS TRAP: Nitrosomonas converts Ammonia into Nitrite (NO2-), whereas Nitrobacter converts Nitrite into Nitrate (NO3-)—the form plants absorb!
Eutrophication, Algal Blooms, Biological Oxygen Demand (BOD) vs. COD & Winterkill
How nutrient enrichment (Nitrates & Phosphates) suffocates aquatic life.
- Cultural Eutrophication: Nutrient enrichment of lakes by agricultural runoff (fertilizers rich in Nitrates & Phosphates) and sewage triggers explosive Algal Blooms on the surface, blocking sunlight to submerged plants.
- Dissolved Oxygen (DO) vs BOD vs COD:
• BOD (Biological Oxygen Demand): Amount of dissolved oxygen needed by aerobic bacteria to decompose biodegradable organic matter only (measured over 5 days at 20°C).
• COD (Chemical Oxygen Demand): Measures oxygen required to chemically oxidize BOTH biodegradable AND non-biodegradable organic pollutants. Therefore, COD is ALWAYS higher than BOD! - Inverse Rule: Higher pollution \Rightarrow Higher BOD/COD \Rightarrow Lower Dissolved Oxygen (DO) (below 4 mg/L stresses fish; below 2 mg/L creates hypoxic "Dead Zones").
⚡ PRELIMS TRAP: BOD measures ONLY biodegradable organic matter, whereas COD measures BOTH biodegradable and non-biodegradable organic matter!
Primary vs. Secondary Succession, Pioneer Species, Autogenic vs. Allogenic
How bare rock or water transforms into a mesic climax forest.
- Primary Succession (Starts on a sterile, lifeless substrate with ZERO soil): Occurs on cooled lava, newly exposed glacial moraine, bare rock (Lithosere/Xerosere), or newly formed pond (Hydrosere). Pioneer Species on rock = Lichens (secrete acids to weather rock into soil); Pioneer in water = Phytoplankton.
- Secondary Succession: Occurs where a pre-existing community was destroyed by fire, flood, or farming, leaving intact soil and seeds behind. It is much faster than primary succession.
- Autogenic vs Allogenic Succession: Autogenic is driven by the living inhabitants of the community themselves (modifying soil/shade); Allogenic is driven by external geophysical forces (volcanoes, climate shifts, floods).
⚡ PRELIMS TRAP: Both Hydrarch (wet) and Xerarch (dry) successions ultimately converge toward a medium-water condition called MESIC (Mesarch Climax Forest)!
Norman Myers’ 2 Strict Hotspot Criteria & Keystone, Indicator, Umbrella & Flagship Species
The exact quantitative thresholds for a Biodiversity Hotspot and functional species roles.
- Norman Myers’ 2 Quantitative Criteria for a Biodiversity Hotspot (Conservation International):
1. Must contain at least 1,500 species of vascular plants (0.5% of world total) as ENDEMICS.
2. Must have lost at least 70% of its original primary native vegetation (i.e., have ≤ 30\% of its original natural habitat remaining). - Functional Species Archetypes:
• Keystone Species: Has a disproportionately huge impact on ecosystem structure relative to its abundance (e.g., Sea Otter, Tiger, Fig Tree, Elephants, Pollinators/Bees). Its removal causes trophic cascade collapse.
• Indicator Species: Extremely sensitive to environmental change (e.g., Lichens = SO2 air pollution indicator; Frogs/Amphibians; Stoneflies/Mayflies = clean water; Tubifex worm = polluted water).
• Flagship Species: Charismatic icon chosen to rally public conservation support (e.g., Giant Panda, Bengal Tiger, One-Horned Rhino).
• Umbrella Species: Wide-ranging species (like the Tiger) whose conservation automatically protects hundreds of co-occurring species in the same large habitat.
⚡ PRELIMS TRAP: Lichens are hyper-sensitive to Sulphur Dioxide (SO2) and completely disappear in SO2-polluted industrial cities!
National Park vs. Wildlife Sanctuary vs. Conservation/Community Reserves (WPA 1972)
Boundary alteration rules, grazing rights, and the 2022 Wildlife Protection Amendment changes.
- National Park (NP) vs Wildlife Sanctuary (WS):
• Livestock Grazing: Completely PROHIBITED in a National Park; may be regulated/permitted by the Chief Wildlife Warden inside a Wildlife Sanctuary.
• Human Rights (Collector’s Inquiry): In a Sanctuary, certain existing rights of local residents may be allowed to continue; in a National Park, NO human rights or private landholding are allowed.
• Species Focus: A Sanctuary can be created for a specific species (e.g., Grizzled Giant Squirrel WS), whereas a National Park protects the entire ecosystem/habitat without species-specific bias.
• Boundary Alteration: Neither NP nor WS boundaries can be altered by a State Govt without the recommendation of the National Board for Wildlife (NBWL — chaired by the Prime Minister!). - Conservation Reserves & Community Reserves (Added by 2002 Amendment): Conservation Reserves are on uninhabited State Govt-owned land acting as buffer/corridors; Community Reserves are on private or community land.
⚡ PRELIMS TRAP: A Wildlife Sanctuary can be upgraded into a National Park, but a National Park can NEVER be downgraded into a Wildlife Sanctuary!
Wildlife Protection Act (1972) Bodies & The 2022 Amendment (6 Schedules → 4 Schedules)
Crucial update for UPSC Prelims: the 6 Schedules of WPA 1972 were rationalized into 4 Schedules in 2022!
- 5 Statutory Bodies under WPA 1972:
1. NBWL (National Board for Wildlife — Chaired by Prime Minister; standing committee chaired by Environment Minister).
2. NTCA (National Tiger Conservation Authority, 2005 — Chaired by Environment Minister).
3. CZA (Central Zoo Authority, 1992 — Chaired by Environment Minister).
4. WCCB (Wildlife Crime Control Bureau, 2007 — HQ: New Delhi).
5. NBSAP / CITES Management Authority. - Wild Life (Protection) Amendment Act, 2022 (Rationalized 6 Schedules into 4 Schedules!):
• Schedule I: Animal species with the highest level of protection.
• Schedule II: Animal species with a lesser degree of protection.
• Schedule III: Protected Plant species.
• Schedule IV: Specimens listed in the Appendices under CITES (Scheduled specimens).
(Note: The old "Vermin" schedule [old Schedule V] was removed!).
⚡ PRELIMS TRAP: NBWL is chaired by the PRIME MINISTER, whereas NTCA and CZA are chaired by the UNION MINISTER OF ENVIRONMENT, FOREST & CLIMATE CHANGE!
India’s 18 Biosphere Reserves & The 12 UNESCO MAB Network Sites
Chronology from Nilgiri (1986) to Panna, and which 6 Indian BRs are NOT in the UNESCO MAB list.
- 18 Biosphere Reserves in India:
• First BR (1986): Nilgiri (TN, Kerala, Karnataka).
• Largest BR by Area: Great Rann of Kutch (Gujarat —Indian Wild Ass).
• Smallest BR by Area: Dibru-Saikhowa (Assam). - 12 Indian BRs in UNESCO’s Man and the Biosphere (MAB) Network: Nilgiri, Gulf of Mannar, Sundarbans, Nanda Devi, Nokrek, Pachmarhi, Simlipal, Achanakmar-Amarkantak, Great Nicobar, Agasthyamala, Khangchendzonga, and Panna (added 2020).
- The 6 Indian BRs NOT in UNESCO MAB (Memorize to eliminate options!): 1. Manas (Assam), 2. Dibru-Saikhowa (Assam), 3. Dihang-Dibang (Arunachal), 4. Cold Desert (Himachal), 5. Kachchh (Gujarat), and 6. Seshachalam Hills (Andhra Pradesh).
⚡ PRELIMS TRAP: Remember the 6 NON-MAB Biosphere Reserves (Manas, Dibru-Saikhowa, Dihang-Dibang, Cold Desert, Kachchh, Seshachalam)—all other 12 ARE in UNESCO MAB!
Project Tiger (1973), Project Elephant (1992), M-STrIPES, MIKE & Project Cheetah
Launch years, monitoring technologies, and key reserves across India.
- Project Tiger (1 April 1973 — Launched from Jim Corbett NP): Administered by NTCA (statutory body since 2006). Uses M-STrIPES (Monitoring System for Tigers - Intensive Protection and Ecological Status) android GPS app & pugmark/camera-trap census every 4 years. India hosts >70\% of the world’s wild tigers across 55+ Tiger Reserves.
- Project Elephant (1992 — Centrally Sponsored Scheme): Protects elephants and their corridors (33 Elephant Reserves; Gaj Yatra & Gaj Soochna). MIKE (Monitoring the Illegal Killing of Elephants) is a CITES program (launched 2003) operating across 10 sites in India (Chirang-Ripu, Dihing Patkai, Eastern Dooars, Deomali, Garo Hills, Mayurbhanj, Mysore, Nilgiri, Shivalik, Wayanad).
- Other Key Conservation Milestones: Project Crocodile (1975), Project Rhino (2005 — Indian Rhino Vision 2020), Project Snow Leopard (2009), Project Dolphin (2020 — Gangetic Dolphin = National Aquatic Animal), Project Cheetah (2022 — African Cheetahs translocated from Namibia & South Africa to Kuno National Park, MP).
⚡ PRELIMS TRAP: Asian Elephants (Elephas maximus) are Endangered on the IUCN Red List; only MALE Asian elephants have tusks (unlike African elephants where both sexes have tusks), and the oldest female (Matriarch) leads the herd!
Forest Rights Act (2006), CAMPA (2016) & Bamboo Exemption (2017 Amendment)
Which ministry administers FRA 2006, Critical Wildlife Habitats, and Minor Forest Produce.
- Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006 (FRA):
• Nodal Ministry: Ministry of Tribal Affairs (MoTA)—NOT the Environment Ministry!
• Initiating Authority: The Gram Sabha is the sole authority to initiate the process for determining individual (up to 4 hectares) and community forest rights.
• OTFD Requirement: Other Traditional Forest Dwellers must prove residence for 3 generations (75 years) prior to 13 Dec 2005.
• Critical Wildlife Habitat (CWH): Defined under FRA 2006 (not WPA 1972!), declared inside NPs/Sanctuaries as inviolate areas. - Indian Forest (Amendment) Act, 2017 (Bamboo Rule): Exempted Bamboo grown in NON-FOREST areas from the definition of "Tree"—so farmers no longer need felling/transit permits for bamboo grown on private land!
- CAMPA Act, 2016: Shares Compensatory Afforestation Fund money in a 90% (State Fund) : 10% (National Fund) ratio.
⚡ PRELIMS TRAP: "Critical Tiger Habitat" is notified under the Wildlife Protection Act (1972), whereas "Critical Wildlife Habitat" is notified under the Forest Rights Act (2006)!
Global Warming Potential (GWP) vs. Atmospheric Lifetime & The 7 Kyoto/Doha Gases
Why SF6 has the highest GWP while CO2 causes the most total warming.
- Most Abundant Natural GHG vs Largest Anthropogenic Driver: Water Vapour (H2O) is the most abundant greenhouse gas overall (positive feedback loop), whereas Carbon Dioxide (CO2) is the largest anthropogenic contributor (~64%) to radiative forcing.
- Global Warming Potential (GWP over 100 years, relative to CO2 = 1):
1. Carbon Dioxide (CO2): GWP = 1 (persists for centuries).
2. Methane (CH4): GWP ≈ 28–30 (Lifetime: ~12 years; sources: wetlands, paddy fields, cattle belching, termites, coal mines).
3. Nitrous Oxide (N2O): GWP ≈ 265–298 (Lifetime: ~114 years; sources: urea fertilizers, aviation).
4. HFCs & PFCs: GWP = 1,400–12,000.
5. Sulphur Hexafluoride (SF6 — electrical switchgear insulator): Highest GWP (≈ 23,500) & lifetime of 3,200 years!
6. Nitrogen Trifluoride (NF3): Added in the Doha Amendment (2012) as the 7th Kyoto gas ( extGWP ≈ 16,100).
⚡ PRELIMS TRAP: Methane has a much HIGHER GWP (~28x) than CO2, but a much SHORTER atmospheric lifetime (~12 years) than CO2 or N2O!
Kyoto Protocol’s 3 Market Mechanisms (CDM, JI, Emissions Trading) & Paris Article 6
Certified Emission Reductions (CERs), Annex-I vs Non-Annex-I, and Carbon Credits.
- Common But Differentiated Responsibilities (CBDR): Under Kyoto (adopted 1997, entered into force 2005), only developed countries (Annex-I) had binding emission reduction targets; developing nations like India and China (Non-Annex-I) had no binding caps.
- The 3 Kyoto Flexibility Mechanisms:
1. Clean Development Mechanism (CDM — Article 12): An Annex-I (developed) country invests in a clean energy project inside a Non-Annex-I (developing) country (like India) and earns Certified Emission Reduction (CER) credits (1 CER = 1 metric tonne of CO2 equivalent).
2. Joint Implementation (JI — Article 6): An Annex-I country invests in an emission-reduction project in another Annex-I country to earn Emission Reduction Units (ERUs).
3. International Emissions Trading (Carbon Cap-and-Trade): Trading of Assigned Amount Units (AAUs). - Green/Blue/Teal/Black/Brown Carbon: Green Carbon (terrestrial forests), Blue Carbon (coastal mangroves, salt marshes, seagrass beds), Teal Carbon (freshwater inland wetlands), Black Carbon (soot — PM2.5 solid particles that lower ice albedo), Brown Carbon (biomass burning organic aerosols).
⚡ PRELIMS TRAP: CDM is between a Developed (Annex-I) country and a Developing (Non-Annex-I) country, whereas Joint Implementation (JI) is strictly between TWO Developed (Annex-I) countries!
Why the Ozone Hole is Worst Over Antarctica (Polar Stratospheric Clouds) & Vienna/Montreal/Kigali
The role of the Polar Vortex, Type-II Polar Stratospheric Clouds (PSCs), and Chlorine radicals.
- Good Ozone vs Bad Ozone: 90% of ozone is in the Stratosphere (15–35 km; measured in Dobson Units [DU]; absorbs lethal UV-B & UV-C rays). The remaining 10% in the Troposphere is a toxic secondary air pollutant and greenhouse gas (component of Photochemical Smog).
- Why the Ozone Hole is Deepest Over Antarctica in Spring (Sept–Nov):
1. During the freezing Antarctic winter night, a strong Polar Vortex isolates the air and temperatures drop below -80^°C, forming Polar Stratospheric Clouds (PSCs / Nacreous Clouds).
2. Ice crystals in PSCs provide a solid surface that converts inactive chlorine reservoirs (HCl, ClONO2) into reactive Cl2 gas.
3. When Antarctic Spring sunlight returns in September, UV light splits Cl2 into free Chlorine radicals (Cl^•), where a single Cl^• atom catalytically destroys up to 100,000 Ozone (O3) molecules!
⚡ PRELIMS TRAP: Polar Stratospheric Clouds (PSCs) + returning Spring Sunlight are the two essential triggers for the seasonal Antarctic Ozone Hole!
Classical (London) vs. Photochemical (Los Angeles) Smog, Acid Rain, AQI (8 Pollutants) & Fly Ash
Comparing reducing vs oxidizing smog and the exact 8 pollutants in India’s National Air Quality Index.
- Classical (London / Sulphurous) Smog vs Photochemical (Los Angeles) Smog:
• Classical Smog: Occurs in cool, humid winter mornings from coal burning (Smoke + Fog + SO2). Chemically REDUCING.
• Photochemical Smog: Occurs in warm, dry, sunny climates when sunlight acts on vehicular Nitrogen Oxides (NOx) + Volatile Organic Compounds (VOCs) to form Ground-level Ozone (O3), PAN (Peroxyacetyl Nitrate), and Acrolein. Chemically OXIDIZING. - 8 Pollutants in India’s National Air Quality Index (AQI — CPCB, 2014): PM10, PM2.5, NO2, SO2, CO, O3, NH3 (Ammonia), and Pb (Lead).
(CRITICAL TRAP: Carbon Dioxide [CO2] and Methane [CH4] are NOT included in the 8 AQI pollutants! Benzene, Benzo(a)pyrene, Arsenic, and Nickel are in the 12 NAAQS list, not the 8 AQI list). - Coal Fly Ash Composition: Contains Silicon dioxide (SiO2), Aluminium oxide (Al2O3), Calcium oxide (CaO), and trace toxic heavy metals (Arsenic, Lead, Mercury); used in Portland cement, bricks, and road embankments.
⚡ PRELIMS TRAP: Carbon Monoxide (CO) and Ozone (O3) ARE part of the 8 AQI pollutants, but Carbon Dioxide (CO2) is NOT part of AQI!
Heavy Metal Diseases (Minamata, Itai-Itai, Blue Baby) & Bioremediation Techniques
Matching water pollutants to their clinical syndromes and in-situ vs ex-situ bioremediation.
- Pollutant-Disease Matching (High-Yield Prelims Table):
• Mercury (Hg): Minamata Disease (neurological poisoning) — governed by the Minamata Convention (2013).
• Cadmium (Cd): Itai-Itai ("Ouch-Ouch") Disease (severe bone softening & kidney failure).
• Nitrates (NO3^- in drinking water): Blue Baby Syndrome (Methemoglobinemia).
• Arsenic (As): Blackfoot Disease & keratosis.
• Fluoride (F^-): Skeletal & Dental Fluorosis (Knock-Knee Syndrome). - Bioremediation Techniques:
• In-Situ Bioremediation: Bioventing (pumping air/nutrients into unsaturated soil), Biosparging (injecting air below the water table), Bioaugmentation (adding engineered microbes like Oilzapper / Oilivorous-S developed by TERI).
• Ex-Situ Bioremediation: Landfarming, Biopiles, Windrows, Bioreactors.
⚡ PRELIMS TRAP: Bioventing, Biosparging, and Bioaugmentation are IN-SITU bioremediation methods, whereas Landfarming and Biopiles are EX-SITU methods!
Ramsar Convention (1971), Wise Use Principle & India’s 2 Sites in the Montreux Record
Which two Indian wetlands are currently listed in the Montreux Record (and why Chilika was removed).
- Ramsar Convention on Wetlands (Adopted 2 Feb 1971 in Ramsar, Iran; Force: 1975): The only global treaty focused on a single ecosystem. Core philosophy is the "Wise Use of Wetlands". India has 85+ Ramsar Sites (Tamil Nadu has the highest number; Sundarbans is the largest Ramsar site in India by area; Renuka Wetland in HP is the smallest).
- The Montreux Record (Established 1990): A register of Ramsar sites where changes in ecological character have occurred, are occurring, or are likely to occur as a result of technological developments, pollution, or human interference.
• Currently in Montreux Record from India (ONLY 2 SITES!):
1. Keoladeo National Park (Bharatpur, Rajasthan)
2. Loktak Lake (Manipur — famous for floating Phumdis and the Sangai dancing deer at Keibul Lamjao NP).
• Removed from Montreux Record: Chilika Lake (Odisha) was placed on the record in 1993 due to siltation, but was REMOVED in 2002 after successful restoration by the Chilika Development Authority (winning the Ramsar Wetland Conservation Award)!
⚡ PRELIMS TRAP: Chilika Lake is NO LONGER in the Montreux Record! Only Keoladeo National Park (Rajasthan) and Loktak Lake (Manipur) are currently in the Montreux Record from India.
Convention on Biological Diversity (CBD): Cartagena, Nagoya (ABS), Aichi & Kunming-Montreal 30x30
Distinguishing the 2 supplementary protocols to CBD and the 30x30 target of COP15.
- Convention on Biological Diversity (CBD — 1992 Rio, Legally Binding): Has 3 main goals: (1) Conservation of biodiversity, (2) Sustainable use of its components, and (3) Fair and equitable sharing of benefits arising from genetic resources. (Note: The USA signed but NEVER ratified the CBD!).
- The 2 Supplementary Protocols to CBD:
1. Cartagena Protocol on Biosafety (2000; Force 2003): Regulates transboundary movement of Living Modified Organisms (LMOs) via Advance Informed Agreement (AIA) procedures.
2. Nagoya Protocol on Access and Benefit-Sharing (ABS — Adopted 2010 in Nagoya, Japan; Force 2014): Ensures prior informed consent and fair sharing of benefits from utilizing genetic resources and traditional knowledge (paired with the 2011–2020 Aichi Biodiversity Targets). - Kunming-Montreal Global Biodiversity Framework (COP15, Dec 2022): Adopted the historic "30x30 Target"—to conserve and manage at least 30% of the world’s terrestrial, inland water, and coastal/marine areas by 2030!
⚡ PRELIMS TRAP: Cartagena = Biosafety (LMOs/GMOs); Nagoya = Access and Benefit Sharing (ABS) + Aichi Targets; Kyoto = Climate Change GHGs; Minamata = Mercury!
The Triple Chemical Conventions: Basel (1989), Rotterdam (1998) & Stockholm (2001)
Prior Informed Consent (PIC), Persistent Organic Pollutants (Dirty Dozen), and Transboundary Waste.
- 1. Basel Convention (1989; Force 1992): Controls Transboundary Movements of Hazardous Wastes and Their Disposal (prevents developed nations from dumping toxic/plastic/electronic waste in developing nations without consent). (Note: Radioactive waste is excluded and covered by IAEA).
- 2. Rotterdam Convention (1998; Force 2004): Establishes a legally binding Prior Informed Consent (PIC) Procedure for certain Hazardous Chemicals and Pesticides in International Trade.
- 3. Stockholm Convention (2001; Force 2004): Global treaty to eliminate or restrict the production and use of Persistent Organic Pollutants (POPs)—initially targeting the "Dirty Dozen" (Aldrin, Chlordane, DDT, Dieldrin, Endrin, Heptachlor, Mirex, Toxaphene, PCBs, Hexachlorobenzene, Dioxins, Furans).
⚡ PRELIMS TRAP: The Global Environment Facility (GEF) serves as the financial mechanism for 6 major conventions: CBD, UNFCCC, UNCCD, Stockholm (POPs), Minamata (Mercury), and the High Seas BBNJ Treaty!
IUCN vs. CITES (Washington) vs. TRAFFIC vs. Bonn Convention (CMS)
Understanding which bodies are intergovernmental treaties vs NGOs vs joint programs.
- 1. IUCN (International Union for Conservation of Nature, 1948 — HQ: Gland, Switzerland): Composed of BOTH government and civil-society/NGO members (NOT a UN organ!). Has Observer Status at the UN General Assembly and publishes the Red Data Book (pink pages = critically endangered; green pages = recovered species).
- 2. CITES (Convention on International Trade in Endangered Species, 1973 Washington; Force 1975): Legally binding on member states (though it does not take the place of national laws). Appendix I (species threatened with extinction — commercial trade prohibited), Appendix II (strictly regulated trade), Appendix III (protected in at least one country).
- 3. TRAFFIC (1976 — HQ: Cambridge, UK): A joint wildlife trade monitoring program of WWF and IUCN (it is a non-governmental organization/network, NOT an intergovernmental bureau under UNEP!).
- 4. Bonn Convention (CMS — Convention on the Conservation of Migratory Species of Wild Animals, 1979): Only global UN treaty under UNEP dedicated exclusively to conserving terrestrial, avian, and marine migratory species (India hosted CMS COP13 at Gandhinagar in 2020 with the Great Indian Bustard as mascot).
⚡ PRELIMS TRAP (Asked in UPSC 2017): TRAFFIC is a joint non-governmental program of WWF and IUCN—it is NOT a bureau under UNEP!
Statutory Parent Acts of NGT, CPCB, AWBI, NBA, NTCA, CZA & GEAC
A classic UPSC Prelims trap: matching Indian environmental bodies to the exact Act that created them.
- 1. CPCB (Central Pollution Control Board): Constituted in Sept 1974 under the Water (Prevention and Control of Pollution) Act, 1974; later entrusted with powers under the Air Act, 1981!
- 2. AWBI (Animal Welfare Board of India, 1962 — Pioneered by Rukmini Devi Arundale; HQ shifted to Ballabhgarh, Haryana): Statutory body established under Section 4 of the Prevention of Cruelty to Animals Act, 1960 (NOT under WPA 1972!).
- 3. GEAC (Genetic Engineering Appraisal Committee): Statutory body notified under the Environment (Protection) Act, 1986 (Rules 1989) to approve GM crops (Bt Cotton is the only commercially approved GM crop in India; DMH-11 Mustard & Bt Brinjal have been debated).
- 4. NGT (National Green Tribunal — NGT Act, 2010): Guided by Principles of Natural Justice (not bound by CPC 1908); disposes of cases within 6 months. Can adjudicate cases under 7 Acts (Water, Air, EPA, Forest Conservation, Biodiversity, Public Liability), EXCEPT the Wildlife Protection Act (1972) and Indian Forest Act (1927)/FRA (2006)!
⚡ PRELIMS TRAP (Asked in UPSC): The National Green Tribunal (NGT) has ZERO jurisdiction over cases under the Wildlife (Protection) Act, 1972 and the Forest Rights Act, 2006!
UNFCCC COP Landmarks (COP3 to COP28) & India-Led Global Alliances (ISA, CDRI, IBCA, LiFE)
Green Climate Fund, Loss and Damage Fund, International Solar Alliance, and Big Cat Alliance.
- Landmark UNFCCC COP Summits:
• COP3 (Kyoto, 1997): Kyoto Protocol.
