Tropical Forest Forever Facility (TFFF)

Why in the News?

Brazil, the host of COP30, has proposed the Tropical Forest Forever Facility (TFFF) to finance conservation of standing forests.

What is Tropical Forest Forever Facility (TFFF)?

  • Nature: A global blended finance fund that pays Tropical Forest Countries (TFCs) per hectare of forest conserved.
  • Adjustments: Deductions made for deforestation or degradation.
  • Equity Provision: At least 20% of payments reserved for Indigenous Peoples & Local Communities (IPLCs).
  • Monitoring: Payments tracked via satellite systems and managed by a TFFF Secretariat.
  • Relation to REDD+: Complements but does not replace REDD+; no carbon credits or project-based offsets.

Financial Mechanism:

  • Core Instrument: Tropical Forest Investment Fund (TFIF) under a Multilateral Development Bank (likely World Bank).
  • Funding Sources:
    • Sponsors (20%): High-income countries and philanthropies, via concessional loans/grants.
    • Market Investors (80%): Institutional investors, sovereign wealth funds, university endowments.
  • Investment Strategy: Invests in liquid public bonds (US Treasuries), corporate bonds (Apple), green/blue bonds; excludes fossil fuels.
  • Returns & Payments: Earnings from investments fund result-based payments to TFCs, with 2% annual increase for inflation.

Key Hurdles:

  • Financing Burden: Global South may indirectly finance its own conservation as TFIF invests in their markets with higher borrowing costs.
  • Credit Rating Dependence: Returns hinge on ratings by Fitch, S&P, Moody’s.
  • Geopolitical Risk: Reliance on World Bank (US dominance) may skew control.
  • IPLC Gap: Despite pledges, historically Indigenous Peoples & Local Communities (IPLCs) receive <1% of climate aid.
  • Forest Definitions: Disputes over canopy thresholds (20–30%) may disadvantage sparser forest nations.

Back2Basics: REDD+ (Reducing Emissions from Deforestation and Forest Degradation plus)

  • Launch: 2008 as a UN collaborative initiative (FAO, UNDP, UNEP); now >65 partner countries.
  • Framework: Under UNFCCC; incentivizes developing nations to cut emissions and improve forest carbon stocks.
  • ‘+’ Component: Adds conservation, sustainable management, and carbon stock enhancement.
  • Objectives: Financial incentives for verified actions in (1) reducing deforestation, (2) reducing degradation, (3) conservation, (4) sustainable management, (5) carbon enhancement.
  • Mechanism: Countries prepare national strategies, monitor/report, and get results-based payments for verified emission reductions.

Supreme Court Guidelines on DNA Evidence in Criminal Cases

Why in the News?

The Supreme Court has issued guidelines in the Kattavellai @ Devakar v. State of Tamil Nadu Judgement to standardise DNA handling in criminal cases to prevent contamination and delays after evidence lapses in a major case.

Key Highlights of the Supreme Court Guidelines:

  • Case Context: It involved rape, murder, and robbery. Court flagged delays in Forensic Science Laboratory (FSL) submission, lack of chain of custody, and risk of contamination.
  • Need: Lack of uniform procedures across states despite scattered rules. Since Police and Public Order are in the State List, Supreme Court intervened for national uniformity.
  • Guidelines Issued:
    • Collection and Documentation: Samples must be packaged properly, labelled with FIR details, and signed by medical officer, Investigating Officer, and witnesses.
    • Transportation: Investigating Officer (IO) must deliver samples to FSL within 48 hours. Reasons for any delay must be recorded.
    • Storage Pending Trial: Packages cannot be opened or resealed without trial court approval.
    • Chain of Custody Register: Maintained until conviction or acquittal. IO responsible for explaining lapses.

Previous SC Observations on DNA Evidence:

  • Anil v. Maharashtra (2014): DNA reliable only if laboratory procedures are maintained.
  • Manoj v. Madhya Pradesh (2022): DNA rejected as recovery was from open area with contamination risk.
  • Rahul v. Delhi (2022): DNA held inadmissible after being kept in police custody for two months.
  • Pattu Rajan v. Tamil Nadu (2019): DNA value depends on corroborating evidence; absence not fatal.
  • Sharda v. Dharmpal (2003): DNA test orders valid; no violation of Article 21.
  • Das @ Anu v. Kerala (2022): DNA not self-incrimination under Article 20(3). Section 53A CrPC permits collection in rape cases.

Back2Basics: DNA Profiling

  • Overview: DNA profiling, also called DNA fingerprinting, is a forensic technique to identify individuals by analysing unique DNA regions, mainly Short Tandem Repeats (STRs).
  • How it works: Human DNA is 99.9% identical; the 0.1% variability forms the basis of personal identification.
  • Sources: DNA can be extracted from blood, semen, saliva, hair, bone, skin, or even “touch DNA.”
  • Processes: The process includes isolation, purification, amplification, visualization, and statistical comparison of DNA markers.
  • Methods:  miniSTRs and mitochondrial DNA (mtDNA) help in degraded or limited samples.
  • Legal Status: Treated as expert opinion under Indian Evidence Act Section 45 (now BSA 2023 Section 39). DNA is corroborative, not substantive evidence.

Biofuel Policy

PM inaugurated India’s first Bamboo-based Ethanol Plant

Why in the News?

PM has inaugurated the world’s first bamboo-based ethanol plant in Golaghat district, Assam, marking a significant step in India’s green energy journey.

Note: Ethanol is prepared from bamboo using a multi-step biochemical conversion process that transforms its rich cellulose content into fermentable sugars, which are then fermented and distilled into ethanol.

About Assam Bioethanol Plant:

  • Overview: World’s first 2G bamboo-based bioethanol facility, developed jointly by Numaligarh Refinery Limited (NRL), Fortum (Finland), and Chempolis OY.
  • Feedstock: Uses 5 lakh tonnes of green bamboo annually, sourced from Assam, Arunachal Pradesh, and other NE states.
  • Production Capacity: Generates 48,900 MT ethanol, 11,000 MT acetic acid, 19,000 MT furfural, and 31,000 MT food-grade CO₂ per year.
  • Benefits: Adds ~₹200 crore annually to Assam’s rural economy; supports farmers and tribal communities with assured markets.
  • Policy Enabler: Reclassification of bamboo (no longer a tree) allowed free cultivation and harvesting, unlocking industrial potential.

Back2Basics: Regulation of Bamboo in India

  • Earlier Status: The Indian Forest Act, 1927 classified bamboo as a “tree”, though botanically it is a grass.
  • Regulatory Impact: Even in non-forest areas, felling, cutting, and transport of bamboo required permits like timber, discouraging farmers and traders.
  • 2017 Amendment: The Act was amended to remove “bamboos” from the definition of “tree” under Section 2(7), but only for non-forest areas.
  • Policy Goal: Intended to ease regulatory burdens, promote bamboo cultivation and trade, and strengthen agroforestry.
  • Current Rule: Bamboo on private/agricultural land can now be freely grown, cut, and transported without permits; bamboo in forest areas remains regulated.
  • Scientific Alignment: Recognises bamboo correctly as a grass (Poaceae family).
  • Significance: Supports rural farmers, artisans, and tribal communities by making bamboo a viable cash crop.

 

[UPSC 2023] According to India’s National Policy on Biofuels, which of the following can be used as raw materials for the production of biofuels?

    • Manki: Head of pidh (cluster of 8–15 villages), adjudicates inter-village disputes.
  • Pre-British: Purely internal self-rule, no taxation or external sovereign authority.
  • British Codification:
    • Wilkinson’s Rules (1833–37) codified system into 31 rules, formally recognising Mankis/Mundas as British agents.
    • Introduced private property; Ho became raiyats (tenants) instead of communal landholders.
    • Led to demographic influx of dikkus (outsiders), rising from ~1,500 (1867) to ~15,700 (1897).
  • Post-Independence: Kolhan Government Estate dissolved (1947) but Wilkinson’s Rules still operative; Kolhan largely exempt from civil laws.
  • Judicial View: In Mora Ho vs State of Bihar (2000), Patna HC treated Wilkinson’s Rules as customs, not law, but upheld their continuance.
  • Current Practice: System governs village disputes; ~200 vacant posts filled by Gram Sabhas.
  • Criticism: Hereditary leadership limits efficiency; many leaders lack education for modern administration.
  • Reform Debate: Youth demand limiting hereditary succession and inclusion of non-tribal raiyats.
  • Contemporary Role: Remains a symbol of tribal autonomy yet requires modernisation for democratic governance.

Bharat Emission Standards

BS-VII Emission Norms

Why in the News?

To align India’s automobile sector with global standards, the government is planning to introduce BS VII emission norms by 2026-27.

About BS7 Norms:

  • Overview: India’s equivalent of Euro 7 emission standards, aimed at reducing vehicular pollution and aligning with global benchmarks.
  • Coverage: Applies uniformly to cars, vans, buses, trucks, petrol, diesel, hybrid, and electric vehicles.
  • On-Board Monitoring (OBM): New system to monitor tailpipe emissions in real time, covering NOx, ammonia, PM, engine gases.
  • Non-Exhaust Regulation: First-time regulation of brake dust (PM) and tyre microplastics.

Back2Basics: Indian Classical Philosophy

There are 6 classical schools of Indian philosophy in the orthodox (Astika) tradition, which accept the authority of the Vedas:

  1. Nyaya: School of logic and reasoning
  2. Vaisesika:  Atomism and categories of reality
  3. Sankhya: Dualism of consciousness (purusha) and matter (prakriti)
  4. Yoga: Practical discipline based on Patanjali’s Yoga Sutras
  5. Mimamsa (Purva Mimamsa): Ritual action and dharma
  6. Vedanta (Uttara Mimamsa): Philosophy of the Upanishads

Apart from these, there are also heterodox (Nastika) schools, which do not accept Vedic authority, such as Buddhism, Jainism, and Charvaka (materialism).

Historical and Archaeological Findings in News

What was the Harappan Language?

Why in the News?

The Union Culture Ministry has invited experts to present their research on deciphering the Indus Valley script, also known as the Harappan script.

What was the Harappan Language?

Recent Efforts and Theories on the Harappan Script:

  • Taxation & Commerce Theory: Bahata Ansumali Mukhopadhyay argues the script encodes rules of trade and taxation, not phonetic spellings.
  • Religious Hypothesis: Karuna Shankar Shukla claims Indus seals carried Rig Vedic mantras and Puranic references, used mainly for rituals.
  • Proto-Dravidian Claims:
    • Prakash N. Salame (Nagpur engineer) says 90% of symbols represent Proto-Dravidian Gondi, building on Dr. M. C. Kangali.
    • Asko Parpola (Finnish Indologist) supports the Dravidian hypothesis, suggesting a logo-syllabic system of pictograms and rebuses.
    • Bryan K. Wells also backs Proto-Dravidian links.
  • Santali Link: Prabhunath Hembrom connects the script to the Santali language, citing parallels with Parpola’s work.
  • Scholarly Caveats: H. P. Ray stresses need for bilingual objects, contextual clarity, and warns against assuming a single language for the entire civilization.

Back2Basics: Indus Valley Civilization (IVC)

  • Timeline: Flourished 2600–1900 BCE, with roots back to Mehrgarh (7000 BCE).
  • Extent: Covered 1.5 million sq. km across modern India, Pakistan, Afghanistan.
  • Discovery: Excavations at Harappa (1921–22, Daya Ram Sahni) and Mohenjo-daro (1922, R. D. Banerji) confirmed as one civilization by John Marshall.
  • Urban Features: Grid-planned cities, fortified towns, granaries, warehouses, dockyards, drainage systems, advanced water management (wells, reservoirs, Great Bath).
  • Seals & Script: Steatite seals with animal motifs and undeciphered script point to complex administration.
  • Crafts & Finds: Pottery, bead-making, weaving, metallurgy, toys, ornaments, figurines; iconic Dancing Girl, Priest-King, Mother Goddess statues.

 

[UPSC 2001] Which one of the following animals was NOT represented on the seals and terracotta art of the Harappan culture?
