Revision summary
Applied biotech in India includes vaccines, PCR and rapid tests, tissue culture, bio-inputs, biosimilars, and Bt cotton. Public marker-assisted breeding and livestock vaccines are as important as GM headlines. The poor gain first from cheap immunisation and diagnostics, then from clean seed and climate-tolerant varieties. Bt cotton’s income gain was real in some years and later limited by resistance and costs. Without extension, water, and markets, lab achievements stay in journals.
Model answer
Copper italics in this answer — like this — are the key facts. Each one is unpacked in the Facts & figures rail.
Introduction
Applied biotechnology is the use of cells and molecules to make seed, vaccines, diagnostics, enzymes, and bio-inputs. India has real achievements in vaccines, diagnostics, tissue culture, and Bt cotton. These can lift the poor when they cheapen calories, health, and farm risk. They do not lift the poor when patents, irrigation, and extension stay out of reach.
Body
Research and development achievements
- Vaccines: India is a large producer of WHO-prequalified vaccines (including pentavalent, rotavirus, and later COVID platforms). Recombinant hepatitis B and indigenous rotavirus strains are public-health biotech, not only a private brand story.
- Diagnostics: ELISA, PCR, and rapid antigen platforms scaled for TB, HIV, and COVID. Cheaper tests matter more to the poor than a new luxury drug.
- Bt cotton: the main commercial GM crop in India. It cut bollworm losses in many years of the 2000s. Pink bollworm resistance later showed that one gene is not a permanent harvest.
- Tissue culture: banana, potato, and sugarcane planting material raised yields for small growers who can buy clean seed.
- Biofertilisers, biopesticides, and fermentation: rhizobium, trichoderma, and industrial enzymes for food and feed.
- Medical biotech: recombinant insulin, biosimilars, and public-sector work on affordable biologics.
- Public research: ICAR, DBT, CSIR, and universities on marker-assisted breeding, drought and salt lines, and livestock vaccines (for example classical swine fever and veterinary diagnostics).
- GM mustard and other food GM remain politically contested; achievement should not be written as if every file is already in the field.
How this can uplift poorer sections
- Cheaper vaccines and diagnostics cut death and out-of-pocket shock, which is the most direct biotech-to-poverty channel.
- Clean planting material and bio-inputs raise small-farm output without the full chemical bill when extension is honest.
- Bt cotton raised incomes for many commercial smallholders in some periods; it also raised seed cost and did not remove monsoon and price risk. Uplift was real and partial.
- Drought- and flood-tolerant varieties (conventional plus molecular markers, not only GM) protect the poorest rainfed plots first.
- Livestock and fish vaccines protect the asset base of pastoral and small dairy households.
- Skills and MSME fermentation (enzymes, spawn, tissue-culture nurseries) can be rural jobs if quality regulation holds.
- Nutrition: biofortified zinc wheat and iron pearl millet from public breeding help hidden hunger cheaper than a capsule campaign.
Conditions so the poor actually gain
- Public procurement of vaccines and seed, DBT-ICAR extension, and regulation that keeps spurious kits and illegal GM out.
- Do not equate every lab press note with a poor household’s plate.
- Pair biotech with credit, water, and MSP or deficiency payments, or the extra quintal still sells in a crash.

Conclusion
India’s applied biotech record is strongest in vaccines, diagnostics, tissue culture, and a mixed Bt-cotton lesson. Those tools uplift the poor when they are cheap, public, and bundled with water and markets. A gene without an extension worker is not a social policy.

-
Does GM automatically help the poorest farmers?
Only if the trait fits their crop, seed is affordable, and pests do not out-evolve it. Non-GM public breeding often reaches rainfed plots first.
-
Is insulin a poverty tool?
Recombinant insulin and biosimilars cut prices relative to older scarcity. Delivery and diagnosis still decide who lives.

What are the challenges to solid waste management in India? Discuss the governmental policy framework on solid waste management. Discuss the success/failure cases of Delhi and Indore cities highlighting the salient features of their solid waste management initiatives.
Indian Economy
• Rapid urbanization has made solid waste management a critical environmental and public health crisis in India. • Key challenges include lack of source segregation, inadequate processing infrastructure, reliance on unprotected informal workers, and financially weak urban local bodies. • The policy framework relies on the SWM Rules 2016, Swachh Bharat Mission (Urban), and Plastic Waste Management Rules 2016. • Indore succeeded through 100% source segregation, zero dump-site remediation, and strict enforcement with digital monitoring. • Delhi failed due to overloaded legacy landfills (Ghazipur, Bhalswa), lack of decentralization, and fragmented municipal governance. • A successful transition requires moving to a circular economy focused on source segregation, decentralized processing, and polluter accountability.

What is Agentic Artificial Intelligence (AI)? Explain its working. Describe its applications with suitable examples. Discuss the advantages, risks and challenges associated with agentic AI systems.
Indian Economy
Agentic Artificial Intelligence represents an advanced paradigm where AI systems operate with autonomy, setting goals and executing complex workflows without constant human prompts. Unlike traditional generative AI that merely responds to queries, agentic AI uses perception, planning, memory, and tool-use to achieve multi-step objectives. Its applications span across autonomous software engineering, supply chain optimization, and automated financial trading. While offering massive productivity gains and dynamic problem-solving, these systems pose significant risks including lack of transparency, alignment failures, security vulnerabilities, and ethical dilemmas. Governance frameworks and robust guardrails are essential to harness their potential safely.

Mention salient features of 'Mission Drishti'. Discuss the imaging techniques used in the satellite launched on 3rd May 2026. Why is it being considered world's first satellite of its kind?
Indian Economy
Mission Drishti represents a major leap in India's space-based Earth observation capabilities, launched on 3rd May 2026. The mission employs advanced multi-spectral and hyperspectral imaging techniques to capture high-resolution data across various atmospheric and terrestrial layers. It is hailed as a global first due to its unique integration of real-time onboard edge computing with quantum encryption for secure data transmission. The satellite significantly enhances resource management, disaster response, and strategic surveillance. It aligns with India's policy of leveraging space technology for sustainable development and national security.
