• Stakeholder Role: It actively engages stakeholders and rightsholders in decision-making to build social trust and transparency for plan compliance.
• Planning Cycle: The process follows UNESCO-IOC’s 10-step “learning-by-doing” cycle for continuous sustainable ocean management:
  • Organisational Framework: (1) Establishing authority, (2) securing funding, (3) pre-planning the process, and (4) engaging stakeholders.
  • Situation Analysis: 5) Mapping current ecological conditions and (6) forecasting future maritime space demands.
  • Plan Development: (7) Drafting the spatial management plan and (8) implementing formal regulations for ocean activities.
  • Adaptive Feedback: (9) Monitoring performance and (10) refining the strategy for the next cycle.

{GS3 – S&T} Gene Drive Technology for Malaria Control *

• Context (TH): New research has confirmed that genetically modified mosquitoes using Gene Drives can suppress malaria parasites from real-world infections.

Mechanism of Gene Drives in Malaria Control

• Biased Inheritance: Gene drives ensure a modified gene is passed to >90% of offspring, overriding the natural 50% inheritance rule.
• Rapid Spread: The modified trait spreads quickly through mosquito populations over successive generations.
• Two Main Approaches:
  • Population Suppression: Alters fertility genes (e.g., doublesex), leading to the collapse of mosquito populations.
  • Population Modification: Keeps mosquitoes alive but blocks malaria parasite development, stopping transmission.
• Real-world Evidence: Studies in Tanzania showed modified Anopheles gambiae mosquitoes significantly reduce parasite survival from real infections.
• High Efficiency: Split gene drive systems achieved ~94% inheritance of anti-malaria traits in experimental conditions.

{GS3 – S&T} India’s Drug Discovery Ecosystem Needs a Reset

• Context (TH): India aims to shift from generic drugs to innovation, but weak basic research and reliance on foreign data hinder new drug discovery.

Role of Basic Science in Drug Discovery

• Understanding Disease Biology: Identifies what goes wrong at the molecular and cellular levels, forming the foundation for targeted drug development.
• Identifying Drug Targets: Reveals specific proteins, genes, or pathways (e.g., enzymes, receptors) that medicines can act upon.
• Guiding Innovation: Breakthrough therapies (e.g., GLP-1 drugs, enzyme therapies) originate from long-term fundamental research.
• Reducing trial failures: Strong biological understanding improves success rates by ensuring drugs target the correct mechanism.

Gaps in India’s Drug Discovery Ecosystem

• Dependence on Western Data: Use of datasets from the US/Europe, which may not reflect India’s genetic diversity (e.g., different responses to drugs like warfarin across populations).
• Basic R&D Ecosystem: India spends only ~ 0.6-0.7% of GDP on R&D (vs ~2–3% in developed countries), limiting breakthroughs in fundamental biology and early-stage drug discovery.
• Poor Disease Understanding: Limited research on India-specific disease patterns (e.g., high diabetes prevalence with different phenotypes like “thin-fat Indian”) hampers targeted drug development.
• Lack of Patient Data: Absence of large-scale Natural History Studies (NHS) and disease registries (e.g., rare diseases) restricts identification of biomarkers and clinical trial endpoints.
• Innovation Deficit: India remains a global leader in generic drugs (~20% of global supply) but contributes relatively few novel drug molecules.
• Global Comparison: China transitioned from generics to innovation with 100+ drug out-licensing deals.

Measures to Strengthen India’s Drug Discovery Ecosystem

• Boost Basic Research Funding: Increase public R&D spending (from ~0.6-0.7% of GDP to 1.5-2%) and scale schemes like PRIP to support long-term discovery research.
• Develop Indian Biological Datasets: Build population-scale genomic databases (e.g., GenomeIndia initiative) to capture India’s genetic diversity for precision medicine.
• Promote Natural History Studies (NHS): Establish national rare disease registries (aligned with the National Policy for Rare Diseases, 2021) to generate patient data for better drug targeting.
• Strengthen Research Ecosystem: Foster academia–industry collaboration through biotech clusters (e.g., Bengaluru, Hyderabad Genome Valley) and public–private partnerships for research.
• Policy Execution: Effectively implement policies like Bio-E3 and clinical trial reforms to reduce approval timelines and attract global R&D investments.
