Revision summary
Neeranchal backs IWMP, now WDC-PMKSY, as the national watershed effort. Structures slow runoff, cut soil loss, and recharge wells in rainfed blocks. The production gain is cropping intensity and a less risky kharif, plus fodder. MGNREGA and PMKSY convergence turn a trench into a second crop. Borewell over-extraction and unmaintained structures cap the impact.

Introduction
A watershed is a ridge-to-valley unit in which rain is caught, soil is held, and aquifers can recharge. The National Watershed Project in recent Union language is the World Bank–assisted Neeranchal project that backs the Integrated Watershed Management Programme (IWMP), later the Watershed Development Component of Pradhan Mantri Krishi Sinchayee Yojana (WDC-PMKSY). In dry blocks, more grain comes from soil moisture before it comes from a new canal.
Body
What the project does
- Ridge treatment, contour trenches, check dams, farm ponds, and drainage-line structures slow runoff so silt stays on the field and water soaks in.
- Common Guidelines (2008) put a Gram Sabha / Watershed Committee in charge, with a livelihood slice for the landless, not only for landholders.
- Neeranchal (approved 2014–15) was meant to fix IWMP’s weak planning, GIS, and monitoring so structures are placed where hydrology, not a contractor’s convenience, dictates.
- Convergence with MGNREGA, PMKSY (Har Khet Ko Pani and micro-irrigation), and PM-KISAN cash on the same plot is how a trench becomes a second crop.
Impact on production in water-stressed areas
- Cropping intensity rises where a rabi pulse or oilseed can follow a kharif cereal on stored moisture. That is the main production gain in rainfed Deccan, Bundelkhand, Marathwada and parts of Rajasthan and Gujarat.
- Groundwater in treated micro-watersheds often recovers enough for protective irrigation; yields of millets, cotton and horticulture become less of a coin-toss.
- Soil loss falls, so the nutrient capital that Soil Health Cards describe is not washed to the stream. This is yield saved, not only yield added.
- Fodder and trees on bunds support livestock, which is the IFS link: milk smooths the year when the grain crop is thin.
- Pradhan Mantri Fasal Bima Yojana still matters: watersheds cut frequency of total failure; they do not remove drought.
Limits
- Impact is site-specific. Ghost structures, poor maintenance, and upstream–downstream fights waste money.
- A watershed cannot offset power-subsidised borewells that mine deeper than recharge.
- Production gains need seeds, extension and a market; a check dam alone does not raise MSP-linked wheat in a canal command.

Conclusion
In water-stressed areas the National Watershed Project raises agricultural production mainly by holding soil and moisture, then a modest second crop and livestock. Neeranchal and WDC-PMKSY work when MGNREGA and PMKSY converge and when borewells are not allowed to empty the recharge. Treat the ridge first; then talk of yield.

-
Is the National Watershed Project a separate crop scheme?
No. It is a land-and-water programme. Production rises if moisture and then seeds and markets follow.
-
Can a check dam replace PMFBY in drought blocks?
No. It lowers the chance of total washout. Insurance remains the residual cover.

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.
