• Environment: The fourth global mass coral bleaching event is confirmed. 2023-24 ocean heat drove bleaching across all coral reef systems.
• Health: India introduces mandatory NOTTO-ID for all organ transplants to curb commercial dealings involving foreign nationals.
• Agriculture: Forest Rights Act conflicts: 44 per cent arise from conservation projects and 88 per cent from non-implementation of FRA.
• Science: Researchers discover the Nitroplast, the first nitrogen-fixing organelle in eukaryotes, in a marine alga.
• Governance: UNCTAD's Trade and Development Report Update flags that 2023 saw the first net negative resource transfer from developing to developed countries since 2008.

The National Organ and Tissue Transplant Organisation (NOTTO) mandated that all organ transplants in India require a unique NOTTO-ID to prevent illegal organ trade involving foreign nationals.

Key facts:

• NOTTO: A body under the Directorate General of Health Services, Ministry of Health and Family Welfare. Coordinates procurement and distribution of organs and tissues.
• Primary law: Transplantation of Human Organs Act (THOA), 1994. Bans commercial dealings in human organs. Allows "near relatives" and voluntary donations.
• India's ranking: Third-largest number of transplants globally (15,561 in 2022, up from 4,990 in 2013).
• Concern: Private hospitals have been found arranging organs for foreign nationals, circumventing the priority system for Indian patients.
• NOTTO-ID: A unique registration number generated for each transplant. Hospitals must obtain it before proceeding. Creates an audit trail linking donor, recipient, and hospital.
• State domicile removal: An earlier reform removed the requirement for patient registration only in their home state, allowing inter-state transplant access.
• Age provision: Individuals above 65 years can receive organs from deceased donors under the scheme.

A Land Conflict Watch database study found that 44 per cent of land conflicts arise from conservation or forestry projects, and 88 per cent involve non- implementation of the Forest Rights Act, 2006.

Key facts:

• Forest Rights Act (FRA), 2006: Recognises the rights of Scheduled Tribes and other traditional forest dwellers over forests they have lived in for generations. Two types of rights:
  • Individual forest rights: Patta (title) for land under cultivation.
  • Community forest rights: Rights over community forest resources.
• Land titles distributed: Approximately 23.43 lakh individual and community rights titles across states.
• Most affected states: Maharashtra, Odisha, and Madhya Pradesh have the highest share of conflicts.
• High-risk states for implementation gaps: Odisha, Chhattisgarh, and Jammu and Kashmir.
• Infrastructure conflicts: Mining and power sector projects are the largest sources of displacement-related conflict in FRA areas.
• FRA and conservation projects: Conflicts arise when Protected Area extensions or tiger reserve notifications ignore FRA rights. The SC has held that FRA rights must be settled before any forest diversion.

Scientists identified a new cellular organelle called the Nitroplast in the marine alga Braarudosphaera bigelowii.

Key facts:

• Function: The Nitroplast fixes atmospheric nitrogen (N₂) into ammonia (NH₃), a form usable by the cell. Until this discovery, nitrogen fixation in eukaryotes was believed to occur only through bacterial symbionts, never through a dedicated organelle.
• Origin: Evolved from a symbiotic bacterium (UCYN-A) approximately 100 million years ago.
• Key criterion for organelle status: The Nitroplast is inherited through cell division and depends on proteins supplied by the host cell. This distinguishes it from a bacterial endosymbiont.
• Why it matters: The Nitroplast is only the fourth organelle of endosymbiotic origin to be recognised, after the mitochondrion, chloroplast, and Chromatophore. Nitrogen fixation is the most energy-intensive step in the nitrogen cycle. A eukaryotic cell with its own nitrogen-fixing organelle could change agriculture if the capacity is eventually transferred to crops.

NOAA and the International Coral Reef Initiative formally confirmed the 2023-24 mass bleaching event as the fourth in recorded history.

Key facts:

• Cause: Ocean heat driven by El Nino and long-term climate warming pushed sea surface temperatures above the bleaching threshold across all reef systems.
• Scale: Bleaching confirmed in at least 53 countries and territories.
• Great Barrier Reef: Australia's reef, the world's largest coral system, has experienced its fifth mass bleaching since 1998.
• India's reefs: The Lakshadweep Islands, Andaman and Nicobar reefs, and the Gulf of Mannar reef chain are all at risk.
• Soil acidification parallel: A separate study released the same week warned that soil acidification could release 3.3 billion tonnes of soil inorganic carbon over 30 years. The two phenomena both reflect carbon cycle disruption.

A global study warned that soil acidification could affect 30 per cent of India's cultivable land, with the northeastern states most vulnerable.

Key facts:

• Drivers: Industrial pollution and intense nitrogen-based fertiliser use raise soil acidity. Acid deposition (acid rain) from sulphur and nitrogen emissions also contributes.
• Consequences:
  • Lower soil pH impairs nutrient availability, especially phosphorus, calcium, and magnesium.
  • Soil microbe populations decline.
  • Crop yields fall.
  • Carbon sequestration capacity of soil decreases.
• India context: Northeastern India is most vulnerable due to high rainfall and acidic parent rock combined with agricultural intensification.
• Mitigation: Lime application neutralises acidity. Reduced chemical fertiliser use and organic matter addition improve soil health.

UNCTAD's Trade and Development Report Update for April 2024 flagged that 2023 saw the first net negative resource transfer from developing to developed countries since 2008.

Key facts:

• Net negative transfer: Developing countries paid more in debt service, profit repatriation, and capital outflows than they received in new investment and aid.
• Global merchandise trade (2023): Decreased approximately 1 per cent in real terms. Causes: trade tensions, subdued demand, and Red Sea shipping disruptions.
• Debt crisis: Nine low-income countries are in debt distress; 25 more are on the brink.
• UNCTAD: Founded in 1964. Headquartered in Geneva. The main UN body addressing trade and development from a developing-country perspective.

• Pink bollworm: Cotton farmers in Punjab reduced cotton area by 32 per cent in 2023-24 due to severe pink bollworm (Pectinophora gossypiella) infestation. The larva develops a distinctive pink colouring and burrows into cotton bolls, destroying seeds and fibre.
• Space debris milestone: India announced a target of debris-free space missions by 2030, presented at the 42nd annual meeting of the Inter-Agency Space Debris Coordination Committee (IADC). IADC was founded in 1993 and is the internationally recognised authority on orbital debris management.
• Bumblebees and pesticides: A study found that bumblebees show resilience to combined insecticide and fungicide exposure without reduced learning or flight performance, challenging assumptions about pesticide cocktail effects.
