Revision summary
• 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.

Introduction
Rapid urbanization and changing consumption patterns have transformed solid waste management into a critical environmental and public health challenge for India. While comprehensive national policy frameworks exist, municipal implementation remains starkly polarized between systemic failures in metros like Delhi and exemplary urban transformations in cities like Indore.
Body
Systemic Challenges in India
- Unsegregated Waste: Lack of source segregation at the household level severely compromises downstream recycling and processing efficiency.
- Inadequate Infrastructure: Paucity of scientific landfills, waste-to-energy plants, and material recovery facilities leads to indiscriminate dumping.
- Informal Sector Dependence: Over-reliance on informal ragpickers without adequate safety gear, social security, or formal integration creates health vulnerabilities.
- Financial Constraints: Urban local bodies often lack the financial autonomy, revenue streams, and technical capacity to sustain modern waste processing systems.
Governmental Policy Framework
- Solid Waste Management Rules, 2016: Mandated source segregation, extended producer responsibility for packaging waste, and integration of informal waste pickers.
- Swachh Bharat Mission (Urban): Shifted waste management into a national mass movement, driving funding, infrastructure creation, and behavioral change through star ratings.
- Plastic Waste Management Rules, 2016: Introduced bans on identified single-use plastics and enforced strict producer accountability.
Indore: A Success Story
- 100 Percent Source Segregation: Institutionalized rigid segregation of wet, dry, and domestic hazardous waste at source before doorstep collection.
- Zero Dump-Site Mission: Remediation of legacy waste at the Devguradia trenching ground and conversion into decentralized processing units.
- Rigorous Enforcement: Effective deployment of spot fines and digital monitoring via apps to prevent littering and open dumping.
Delhi: Failures and Bottlenecks
- Landfill Overburden: Massive legacy waste mounds at Ghazipur, Okhla, and Bhalswa exceeding structural capacities and causing frequent fires.
- Decentralization Deficit: Over-dependence on centralized dumping rather than localized composting and material recovery.
- Governance Fragmentation: Overlapping jurisdictions between municipal corporations and state agencies leading to diffused accountability.

Conclusion
Effective solid waste management requires shifting from a linear dump-and-forget model to a circular economy anchored in source segregation and decentralized processing. Replicating the Indore model across urban India demands sustained political will, capacity building of local bodies, and strict enforcement of the polluter-pays principle.

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.

How are startups in India promoting entrepreneurship, innovation and employment? Discuss the global and domestic challenges in their working and suggest suitable measures to overcome these challenges.
Indian Economy
India's startup ecosystem drives entrepreneurship, disruptive innovation, and large-scale employment across sectors. However, startups face severe global headwinds like funding winters and protectionism, alongside domestic hurdles such as regulatory compliance, tax burdens, and talent gaps. Overcoming these requires targeted capital access, simplified compliance frameworks, and robust R&D incentives. Strengthening intellectual property regimes and Tier-2/3 incubation will sustain this growth engine. Ultimately, a balanced policy ecosystem ensures sustainable economic resilience and inclusive job creation.
