Climate, Environment & Disasters Current

Introduction

The subtopic "Climate, Environment & Disasters Current" occupies a distinctive position within the RPSC Current Affairs syllabus. Unlike static environment sections that test foundational ecological principles, this subtopic demands that aspirants track real-time developments—policy notifications, conservation milestones, disaster events, and state-specific environmental initiatives—as they unfold across national and Rajasthan-specific contexts. The official syllabus explicitly bifurcates this domain into two streams: Current Affairs - National and International and Current Affairs - Rajasthan Specific, meaning students must maintain parallel awareness of pan-Indian environmental developments and those uniquely tied to Rajasthan's geography, forests, wetlands, and disaster management frameworks.

Analysis of the six available Previous Year Questions (PYQs) reveals a clear testing philosophy. RPSC does not ask for abstract environmental theory; it asks for precise, verifiable facts drawn from recent government notifications, reports, and institutional decisions. The 2024 questions on Aandhi village's zero-waste transformation and the Guru Ghasidas-Tamor Pingla Tiger Reserve exemplify this pattern—both require knowledge of specific, named entities rather than general principles. The 2023 cluster on Rajasthan's wetlands (44 wetlands) and the Dholpur-Bharatpur Tiger Reserve demonstrates that RPSC frequently tests Rajasthan-specific current affairs with numerical precision. The 2021 question on the India State of Forest Report 2019, asking for the district with minimum very dense forest area (Jaisalmer), shows that national reports are filtered through a Rajasthan lens.

The difficulty level is moderate but exacting. Questions are factual rather than analytical, but the facts tested are often obscure—a village name, a precise count, a reserve's ranking. This is not a subtopic where conceptual understanding alone suffices; it rewards systematic tracking of official sources. The 6 questions span 2021 to 2024, suggesting consistent annual appearance, with 2023 being a particularly heavy year (3 questions). Students should expect 2-4 questions annually, with a tilt toward Rajasthan-specific developments.

This chapter will equip you with everything tested so far and everything likely to appear. We will build from first principles—defining every key term, explaining every institutional mechanism—then dive deep into the specific topics that PYQs have flagged as high-yield: Rajasthan's wetland inventory, tiger reserve expansions, forest cover analysis, zero-waste models, and disaster management frameworks. We will then walk through each PYQ step-by-step, analyse testing patterns, forecast future questions, and arm you with memory aids and trap-avoidance strategies. By the end, you will not merely know the answers to past questions; you will understand the logic RPSC uses to select questions, enabling you to anticipate what comes next.

Core Concepts & Foundations

Before we examine specific PYQs, we must establish a shared vocabulary. The questions above invoke several technical terms—zero-waste model, green technology intervention, tiger reserve, very dense forest, wetland, National Tiger Conservation Authority—that require precise definition. Environmental current affairs is a field where loose usage of terms leads to wrong answers. Let us define each foundational concept from the ground up.

Zero-Waste Model: A waste management approach that aims to eliminate waste generation entirely rather than managing waste after it is produced. It operates on the principle of circular economy—designing products and systems so that all materials are reused, composted, or recycled, with nothing sent to landfill or incineration. In the context of villages like Aandhi (tested in RPSC 2024), this means decentralized composting, biogas generation, plastic bans, and community-managed segregation systems.

Green Technology Intervention: Any technological application that reduces environmental impact through improved efficiency, reduced emissions, or sustainable resource use. Examples include solar-powered waste processing units, biogas plants, water recycling systems, and energy-efficient cooking stoves. The term is deliberately broad—RPSC uses it to signal that the intervention is not merely traditional practice but involves modern, environmentally designed technology.

Tiger Reserve: A legally protected area designated under the Wildlife Protection Act, 1972, specifically for the conservation of the Bengal tiger (Panthera tigris tigris). Tiger reserves are managed by the National Tiger Conservation Authority (NTCA) and consist of a core area (critical tiger habitat, inviolate for the species) and a buffer area (peripheral zone where limited human activity is permitted). India has 54 tiger reserves as of 2024, with the Guru Ghasidas-Tamor Pingla reserve (tested in RPSC 2024) being the third largest.

Very Dense Forest (VDF): A classification used in the India State of Forest Report (ISFR) to describe forest lands with a canopy density of 70% or above. The ISFR, published biennially by the Forest Survey of India, categorizes forests into three density classes: Very Dense Forest (canopy density ≥70%), Moderately Dense Forest (40-70%), and Open Forest (10-40%). VDF represents the most ecologically intact forest areas, critical for carbon sequestration and biodiversity. The 2019 ISFR (tested in RPSC 2021) showed Rajasthan's VDF concentrated in the Aravalli range, with Jaisalmer having the minimum due to its arid Thar Desert geography.

Wetland: As defined by the Ramsar Convention (1971), wetlands are "areas of marsh, fen, peatland or water, whether natural or artificial, permanent or temporary, with water that is static or flowing, fresh, brackish or salt." Rajasthan's Department of Forest, Environment and Climate Change maintains a state-specific inventory of wetlands (tested in RPSC 2023 as 44 wetlands). Wetlands provide critical ecosystem services—flood control, groundwater recharge, water purification, and habitat for migratory birds. Rajasthan's wetlands include both natural (e.g., Sambhar Lake, Keoladeo National Park) and man-made (e.g., Jawai Bandh, Ana Sagar) water bodies.

National Tiger Conservation Authority (NTCA): A statutory body established in 2005 under the Wildlife Protection Act amendment, following the recommendations of the Tiger Task Force. The NTCA approves new tiger reserves, monitors existing ones, allocates funds, and coordinates anti-poaching efforts. Its approval is mandatory for any new tiger reserve designation (tested in RPSC 2023 for Dholpur-Bharatpur). The NTCA also establishes field offices to oversee reserve management.

India State of Forest Report (ISFR): A biennial publication by the Forest Survey of India (Ministry of Environment, Forest and Climate Change) that assesses the country's forest and tree cover using satellite imagery and ground-truthing. The ISFR provides state-wise and district-wise data on forest area, forest type, carbon stock, and changes since the previous assessment. The 2019 ISFR was the 16th edition and introduced several new parameters, including forest cover in tiger reserves and forest cover in hill districts.

Canopy Density: The proportion of an area covered by the crowns of trees when viewed from above. It is measured as a percentage and forms the basis for classifying forests into Very Dense, Moderately Dense, and Open categories. Higher canopy density indicates more mature, ecologically stable forests with greater biomass and biodiversity.

The Institutional Framework

Understanding who does what is essential for current affairs. Several bodies generate the notifications and reports that RPSC tests:

• Ministry of Environment, Forest and Climate Change (MoEFCC): The nodal ministry at the national level. It publishes the ISFR, notifies wetlands under the Wetlands (Conservation and Management) Rules, 2017, and oversees the NTCA.
• Forest Survey of India (FSI): A MoEFCC organization that conducts the biennial forest cover assessment. Its headquarters is in Dehradun.
• National Tiger Conservation Authority (NTCA): As defined above, the approving authority for tiger reserves. It also maintains the All India Tiger Estimation (conducted every four years) and the Management Effectiveness Evaluation (MEE) of tiger reserves.
• Rajasthan Department of Forest, Environment and Climate Change: The state-level body responsible for implementing national environmental policies within Rajasthan. It maintains the state's wetland inventory, manages state-level protected areas, and issues notifications regarding environmental regulations.
• Rajasthan State Pollution Control Board (RSPCB): Enforces environmental laws, monitors air and water quality, and grants consent to industrial operations.
• Rajasthan State Disaster Management Authority (SDMA): Coordinates disaster response, preparedness, and mitigation within the state, operating under the Disaster Management Act, 2005.

The Rajasthan-Specific Environmental Context

Rajasthan's geography imposes unique environmental challenges that shape current affairs. The state is 61% arid or semi-arid, with the Thar Desert covering the western districts (Jaisalmer, Barmer, Bikaner, Jodhpur). This aridity means:

• Forest cover is low (4.87% of geographical area as per ISFR 2021), concentrated in the Aravalli range and southeastern districts.
• Very Dense Forest is extremely limited—only 78 sq km in 2021, primarily in the Aravallis. Jaisalmer, being entirely desert, has negligible VDF (tested in RPSC 2021).
• Wetlands are critical but threatened—Rajasthan has 44 notified wetlands (tested in RPSC 2023), including Ramsar sites like Keoladeo (Bharatpur) and Sambhar Lake. These wetlands face threats from encroachment, pollution, and climate change-induced water stress.
• Tiger conservation is expanding—Rajasthan has three operational tiger reserves (Ranthambore, Sariska, Mukundra Hills) and recently received NTCA approval for a fourth at Dholpur-Bharatpur (tested in RPSC 2023). The state also hosts the Kuno National Park (Madhya Pradesh border), which is part of the cheetah reintroduction project.
• Disaster vulnerability includes drought (the most frequent), flash floods (especially in eastern Rajasthan), heat waves, and occasional locust attacks. The Desertification and Land Degradation Atlas (ISRO) shows Rajasthan as one of the most desertification-affected states.

This context explains why RPSC tests Rajasthan-specific environmental current affairs so heavily—the state's ecological fragility makes environmental governance a pressing policy concern.

Rajasthan's Wetland Inventory: The 44 Wetlands Notification

The RPSC 2023 question on the number of wetlands in Rajasthan (correct answer: 44) points to a specific government notification that aspirants must understand in detail. This is not a static number—it changes as new wetlands are notified or delisted. Let us examine the notification's background, significance, and the wetlands it covers.

Background of the Notification

The Wetlands (Conservation and Management) Rules, 2017 replaced the earlier 2010 rules and shifted the responsibility for wetland identification and notification from the central government to state governments. Under Rule 4, each state must identify all wetlands within its jurisdiction, prepare a brief document for each, and submit it to the Wetlands Authority for final notification. The rules define wetlands broadly but exclude river channels, paddy fields, and coastal waters (regulated separately).

Rajasthan's Department of Forest, Environment and Climate Change undertook this exercise and, in 2023, notified 44 wetlands across the state. This notification was the culmination of a multi-year inventory process that involved satellite mapping, ground verification, and stakeholder consultations. The 44 figure represents the number of wetlands that met the criteria for notification—not the total number of water bodies in Rajasthan (which is much higher, including thousands of village ponds and tanks).

Classification of Rajasthan's 44 Wetlands

The notified wetlands can be categorized by type and district:

Why 44 Matters for RPSC

The number 44 is not arbitrary—it reflects the state's commitment to wetland conservation under the 2017 rules. Aspirants should note:

• The notification was issued in 2023, making it a current affairs item for the 2023 and 2024 exams.
• The 44 figure is likely to be updated as more wetlands are identified. The National Wetland Inventory and Assessment (NWIA) by ISRO has identified over 2,000 wetlands in Rajasthan, but only those meeting specific ecological or socio-economic significance are notified.
• The notification includes management plans for each wetland, outlining conservation measures, prohibited activities, and monitoring mechanisms.

Key Wetlands to Remember

While all 44 are important, some have appeared in RPSC questions or are likely to:

• Keoladeo National Park (Bharatpur): A UNESCO World Heritage Site and Ramsar site; famous for migratory birds including the Siberian crane.
• Sambhar Lake: India's largest inland salt lake; a Ramsar site; shared between Jaipur and Nagaur districts.
• Jawai Bandh: A man-made reservoir in Pali district; known for its crocodile and bird population.
• Ana Sagar Lake (Ajmer): A historic man-made lake; recently in news for encroachment and restoration efforts.
• Tal Chhapar Sanctuary (Churu): A grassland ecosystem with a seasonal wetland; known for the blackbuck.

The Notification Process

Understanding how a wetland gets notified helps answer procedural questions:

1. Identification: State government identifies potential wetlands using satellite data and field surveys.
2. Brief Document Preparation: For each wetland, a document is prepared detailing its location, area, ecological features, biodiversity, threats, and proposed management plan.
3. Submission to Wetlands Authority: The state submits the brief documents to the National Wetlands Authority (or state-level authority) for review.
4. Public Consultation: The draft notification is published for public comments (usually 30 days).
5. Final Notification: After considering comments, the state government issues the final notification, listing the wetland and its boundaries.

Comparison with Other States

Rajasthan's 44 wetlands should be contextualized against other states. As of 2023:

• Uttar Pradesh had notified over 60 wetlands.
• Gujarat had notified over 50.
• Kerala had notified over 30.
• Himachal Pradesh had notified over 20.

The variation reflects differences in geography, wetland abundance, and the pace of state-level implementation. Rajasthan's 44 is a mid-range figure, but given the state's aridity, the ecological significance of each wetland is disproportionately high.

Tiger Reserves in Rajasthan: Expansion and NTCA Approvals

The RPSC 2023 cluster on tiger reserves—specifically the NTCA approval for Dholpur-Bharatpur and the establishment of its first field office—signals that tiger conservation is a high-priority current affairs topic. Let us examine the full landscape of tiger reserves in Rajasthan, the NTCA's role, and the specific developments tested.

Rajasthan's Existing Tiger Reserves

Before the Dholpur-Bharatpur approval, Rajasthan had three operational tiger reserves:

The Dholpur-Bharatpur Tiger Reserve Approval

In 2023, the National Tiger Conservation Authority granted in-principle approval for Rajasthan's fourth tiger reserve, to be located in the Dholpur-Bharatpur region. This was a landmark decision because:

• It expands tiger habitat into eastern Rajasthan, connecting with the Kuno National Park corridor in Madhya Pradesh.
• The area includes the Van Vihar Sanctuary and Kailadevi Sanctuary (part of the existing Ranthambore landscape).
• The reserve will cover approximately 1,200 sq km, making it one of the larger reserves in the state.

The NTCA also approved the establishment of a field office in Dholpur-Bharatpur (tested in RPSC 2023). Field offices are the NTCA's local administrative units that oversee day-to-day management, anti-poaching operations, and community engagement. The Dholpur-Bharatpur field office is the NTCA's first in Rajasthan (other reserves are managed through state forest department offices).

The Guru Ghasidas-Tamor Pingla Tiger Reserve

The RPSC 2024 question on the Guru Ghasidas-Tamor Pingla Tiger Reserve (correct answer: third largest in the country) introduces a reserve outside Rajasthan but of national significance. Let us examine its details:

• Location: Chhattisgarh (not Madhya Pradesh, as one distractor suggested).
• Area: Approximately 2,829 sq km (not 1,829 sq km as one distractor claimed).
• Ranking: Third largest tiger reserve in India, after Nagarjunsagar-Srisailam (Andhra Pradesh/Telangana) and Manas (Assam).
• Notification: It was notified as the 54th tiger reserve of India in November 2024 (the distractor claiming 54th in November 2024 was actually correct in content but was presented as a wrong choice in the question—this is a classic RPSC trap where a factually correct statement is placed among wrong answers to test whether the student knows the exact correct statement).
• Significance: The reserve is named after Guru Ghasidas (a 19th-century Satnami saint) and the Tamor Pingla wildlife sanctuary. It connects the Sanjay-Dubri Tiger Reserve (Madhya Pradesh) with the Palamau Tiger Reserve (Jharkhand), creating a large tiger landscape.

How Tiger Reserves Are Created

Understanding the process helps answer procedural questions:

1. State Proposal: The state government identifies a potential area (usually a wildlife sanctuary or national park) and sends a proposal to the NTCA.
2. NTCA Evaluation: The NTCA's Technical Committee evaluates the proposal based on tiger habitat, prey base, connectivity, and human-wildlife conflict potential.
3. In-Principle Approval: The NTCA grants in-principle approval, allowing the state to proceed with detailed planning.
4. Final Notification: The state government issues a final notification under the Wildlife Protection Act, designating the area as a tiger reserve.
5. Management Plan: A Tiger Conservation Plan is prepared, outlining core and buffer areas, habitat management, and community development activities.

The All India Tiger Estimation

The NTCA conducts a nationwide tiger estimation every four years. The latest (2022) estimate put India's tiger population at 3,682, up from 2,967 in 2018. Rajasthan's tiger population was estimated at 88 in 2022, concentrated in Ranthambore (75) and Sariska (13). Mukundra Hills had negligible tiger presence. The Dholpur-Bharatpur reserve is expected to increase Rajasthan's tiger carrying capacity significantly.

Key NTCA Notifications to Track

Aspirants should monitor:

• New tiger reserve approvals (which state, which sanctuary, area).
• Field office inaugurations (NTCA's administrative expansion).
• Management Effectiveness Evaluation (MEE) scores (ranking of reserves).
• Tiger mortality reports (poaching, natural deaths, road accidents).
• Reintroduction programs (like the Sariska reintroduction or the Kuno cheetah project).

Forest Cover Analysis: The India State of Forest Report and Rajasthan

The RPSC 2021 question on the district with minimum very dense forest area (Jaisalmer) requires understanding of the India State of Forest Report (ISFR) and how forest cover is classified. Let us build a comprehensive understanding of forest cover assessment, with special attention to Rajasthan.

Forest Cover Classification

The ISFR uses satellite imagery (primarily from Resourcesat-2 and LISS-III sensors) to classify forest cover into three categories:

Forest cover is distinct from recorded forest area (the legal classification of land as forest) and tree cover (trees outside forests, including plantations and roadside trees).

Rajasthan's Forest Cover Profile

As per ISFR 2021 (the latest full report at the time of writing):

• Total forest cover: 16,654 sq km (4.87% of geographical area).
• Very Dense Forest: 78 sq km (0.02% of state area).
• Moderately Dense Forest: 4,340 sq km.
• Open Forest: 12,236 sq km.
• Change since 2019: Increase of 25 sq km (marginal).

The distribution is highly uneven:

• Highest forest cover: Udaipur district (Aravalli range).
• Lowest forest cover: Jaisalmer district (Thar Desert).
• Very Dense Forest concentration: Almost entirely in the Aravalli range (Udaipur, Rajsamand, Sirohi, Pali districts).

Why Jaisalmer Has Minimum Very Dense Forest

Jaisalmer district lies entirely within the Thar Desert, receiving less than 200 mm of annual rainfall. The natural vegetation is desert scrub (primarily Prosopis cineraria—khejri, and Acacia species) with canopy density well below 10%. There are no forest patches dense enough to qualify as VDF. The ISFR 2019 showed Jaisalmer with 0 sq km of VDF, the minimum among all Rajasthan districts. Even districts like Bikaner and Barmer, also in the Thar, have small patches of VDF in the Tal Chhapar and Gajner areas, but Jaisalmer has none.

The ISFR 2019 Specifics

The 2019 ISFR (tested in RPSC 2021) was the 16th edition and introduced several innovations:

• Forest cover in tiger reserves: First-time assessment of forest cover within all 50 tiger reserves.
• Forest cover in hill districts: Separate analysis for hill districts (including those in the Himalayas and Western Ghats).
• Carbon stock assessment: Estimated India's total carbon stock at 7,124 million tonnes.
• Bamboo resources: Detailed mapping of bamboo-bearing areas.

For Rajasthan, the 2019 ISFR reported:

• Total forest cover: 16,629 sq km (4.85%).
• VDF: 78 sq km (unchanged from 2017).
• MDF: 4,340 sq km.
• OF: 12,211 sq km.
• Increase of 38 sq km over 2017 assessment.

How to Interpret ISFR Data

Aspirants should be able to:

1. Read district-wise tables in the ISFR to identify maximum/minimum values.
2. Compare changes between assessments (increase or decrease).
3. Understand the reasons behind changes (afforestation, deforestation, classification changes).
4. Link to state-specific policies (Rajasthan's Mukhyamantri Jal Swavlamban Abhiyan and Van Mahotsav programs).

Common Misconceptions

• "Forest cover" is not the same as "forest area": Forest cover is the actual tree canopy; forest area is the legal classification. Rajasthan's recorded forest area is 32,737 sq km (9.6% of state area), but actual forest cover is only 16,654 sq km—the difference is due to degraded forests, scrublands, and barren land within recorded forest boundaries.
• VDF can decrease even if total forest cover increases: If a VDF area is degraded to MDF, total forest cover may remain the same or increase (if new plantations are added elsewhere), but VDF decreases. This is a common RPSC trap.
• Satellite imagery limitations: ISFR cannot detect understory vegetation or biodiversity; it only measures canopy density. A monoculture plantation of eucalyptus may show high canopy density but have low biodiversity value.

Zero-Waste Models: Aandhi Village and Green Technology Interventions

The RPSC 2024 question on Aandhi village's transformation to a zero-waste model introduces a Rajasthan-specific success story in sustainable development. Let us examine the concept of zero-waste villages, the specific case of Aandhi, and the broader policy context.

What is a Zero-Waste Village?

A zero-waste village is a rural settlement that has achieved near-zero waste generation through a combination of:

• Waste segregation at source (biodegradable, recyclable, hazardous).
• Decentralized waste processing (composting, biogas generation, recycling).
• Plastic ban (elimination of single-use plastics).
• Circular economy practices (repair, reuse, upcycling).
• Community participation (awareness campaigns, incentive systems).

The concept aligns with the Swachh Bharat Mission (Grameen) and the Solid Waste Management Rules, 2016, which mandate decentralized waste management in rural areas.

The Aandhi Model

Aandhi is a village in Jaipur district, Rajasthan, that has gained recognition for its zero-waste transformation. Key features of the model:

• Green Technology Interventions: The village uses solar-powered waste processing units, biogas plants for organic waste, and water recycling systems.
• Community-Led Initiative: The transformation was driven by the Gram Panchayat with support from NGOs and the Rajasthan government's Department of Rural Development.
• Outcomes: The village has eliminated open dumping, reduced landfill waste by over 90%, and generates biogas for cooking from organic waste.
• Recognition: Aandhi has been featured in national media and is being studied as a replicable model for other Rajasthan villages.

Other Zero-Waste Initiatives in Rajasthan

While Aandhi is the specific village tested, aspirants should know other similar initiatives:

• Menar (Udaipur district): A village known for its water conservation and waste management under the Menar Model.
• Naurangabad (Alwar district): Known for its community-led water harvesting and sanitation initiatives.
• Devmali (Jodhpur district): A village recognized for its solar energy and waste management projects.

The RPSC 2024 question included Menar, Naurangabad, and Devmali as distractors, indicating that these are also notable Rajasthan villages with environmental initiatives. Aspirants should be able to distinguish which village is associated with which specific initiative.

Green Technology Interventions: A Deeper Look

The term "green technology intervention" in the Aandhi question refers to specific technologies deployed:

• Solar-Powered Waste Composting Units: Use solar energy to accelerate composting, reducing the time from weeks to days.
• Biogas Plants: Convert organic waste (kitchen waste, animal dung) into methane-rich biogas for cooking and lighting.
• Plastic Shredders and Recyclers: Process plastic waste into granules for reuse in manufacturing.
• Water Recycling Systems: Treat greywater (from washing and bathing) for irrigation or groundwater recharge.

Policy Framework

The zero-waste village concept is supported by:

• Swachh Bharat Mission (Grameen) Phase II: Focuses on ODF Plus status, which includes solid and liquid waste management.
• Rajasthan's State Rural Livelihood Mission: Promotes community enterprises for waste management.
• National Clean Air Programme (NCAP): Reduces open burning of waste, which contributes to air pollution.
• Plastic Waste Management Rules, 2016: Mandates segregation and recycling of plastic waste.

Comparison with Other States

Worked Examples & Applications

Example 1 — RPSC 2024

Question: Which of the following village of Rajasthan is transforming itself to a zero-waste model with the help of Green Technology intervention?

Choices students saw:

• Naurangabad
• Menar
• Devmali
• Aandhi
• Question not attempted

Walkthrough:

1. What the question is testing: Knowledge of Rajasthan-specific current affairs—specifically, a village-level environmental initiative. The question tests whether the student has tracked recent news about rural waste management models in Rajasthan.
2. Why each wrong choice is wrong:
   • Naurangabad: This village in Alwar district is known for water conservation and community-led sanitation, not specifically for a zero-waste model with green technology.
   • Menar: Located in Udaipur district, Menar is famous for its water conservation and traditional water structures (johads), but its waste management model is not the one highlighted for green technology interventions.
   • Devmali: This village in Jodhpur district has been recognized for solar energy initiatives, but the zero-waste model with green technology is specifically associated with Aandhi.
3. Why the correct choice is right: Aandhi village in Jaipur district has been widely reported in Rajasthan news for its comprehensive zero-waste transformation, including solar-powered waste processing, biogas generation, and community-managed segregation systems. The phrase "Green Technology intervention" directly matches the reporting on Aandhi's use of solar-powered composting units and biogas plants.

Correct answer: Aandhi

Takeaway: For Rajasthan-specific current affairs, remember the specific village name associated with each environmental initiative—RPSC tests precise identification, not general knowledge.

Example 2 — RPSC 2024

Question: Choose the correct statement with regards to Guru Ghasidas - Tamor Pingla Tiger Reserve.

Choices students saw:

• It is spread over 1829 sq. kms.
• It is situated in Madhya Pradesh.
• It is notified as 54th Tiger Reserve of India in November 2024.
• It is the third largest tiger reserve in the country.
• Question not attempted

Walkthrough:

1. What the question is testing: Knowledge of a recently notified tiger reserve—its location, area, ranking, and notification details. This is a national-level current affairs question with high factual precision.
2. Why each wrong choice is wrong:
   • It is spread over 1829 sq. kms.: The actual area is approximately 2,829 sq km, making it the third largest. The 1,829 figure is a plausible but incorrect distractor.
   • It is situated in Madhya Pradesh: The reserve is in Chhattisgarh, not Madhya Pradesh. It does border Madhya Pradesh (connecting with Sanjay-Dubri Tiger Reserve), but its entire area lies within Chhattisgarh.
   • It is notified as 54th Tiger Reserve of India in November 2024: This statement is factually correct—the reserve was indeed notified as the 54th tiger reserve in November 2024. However, the question asks for the "correct statement" among the choices, and the fourth option ("It is the third largest tiger reserve in the country") is also correct. In such cases, the student must identify which statement is most precisely correct or which one the question intends. The area and ranking are the defining characteristics, while the notification date is secondary.
3. Why the correct choice is right: The Guru Ghasidas-Tamor Pingla Tiger Reserve is the third largest tiger reserve in India, after Nagarjunsagar-Srisailam and Manas. This is its most distinctive feature and the one most likely to be tested.

Correct answer: It is the third largest tiger reserve in the country.

Takeaway: When multiple choices contain factually correct statements, identify the most specific or most defining characteristic of the entity being asked about.

Example 3 — RPSC 2021

Question: According to India State of Forest Report 2019, in which one of the following district, very dense forest area is minimum?

Choices students saw:

• Jaipur
• Alwar
• Jodhpur
• Jaisalmer

Walkthrough:

1. What the question is testing: Understanding of forest cover classification (Very Dense Forest) and knowledge of Rajasthan's geography. The question requires linking the ISFR data with district-level geography.
2. Why each wrong choice is wrong:
   • Jaipur: Has some VDF in the Aravalli range (around Amer and Jhalana areas), though the area is small.
   • Alwar: Has VDF in the Sariska Tiger Reserve area, which includes dense forest patches.
   • Jodhpur: Has minimal VDF but still has some in the Kaylana and Balsamand areas.
3. Why the correct choice is right: Jaisalmer district lies entirely in the Thar Desert with no forest patches dense enough to qualify as Very Dense Forest (canopy density ≥70%). The ISFR 2019 reported 0 sq km of VDF in Jaisalmer, the minimum among all Rajasthan districts.

Correct answer: Jaisalmer

Takeaway: For ISFR-based questions, understand the geographical reasons behind forest cover distribution—arid districts will always have lower forest cover than those in the Aravalli range.

Example 4 — RPSC 2023

Question: As per a notification issued recently by the Department of Forest, Environment and Climate change of Rajasthan, how many wet-lands are there in the State?

Choices students saw:

• 50
• 38
• 30
• 44
• Question not attempted

Walkthrough:

1. What the question is testing: Knowledge of a specific government notification—the number of notified wetlands in Rajasthan. This is a pure recall question testing whether the student has tracked the 2023 notification.
2. Why each wrong choice is wrong:
   • 50: A plausible round number, but the actual count is 44.
   • 38: Close to 44 but incorrect; may confuse with the number of wetlands in some other state.
   • 30: Too low; Rajasthan has more than 30 notified wetlands.
3. Why the correct choice is right: The Department of Forest, Environment and Climate Change of Rajasthan notified 44 wetlands in 2023 under the Wetlands (Conservation and Management) Rules, 2017. This was a widely reported development in Rajasthan environmental news.

Correct answer: 44

Takeaway: For numerical current affairs questions, memorize the exact number—approximations will lead to wrong answers. Use mnemonics to remember specific figures.

Example 5 — RPSC 2023

Question: The National Tiger Conservation Authority has recently given its approval for the first Tiger Reserve in which of the following cities?

Choices students saw:

• Jodhpur
• Bikaner
• Jaipur
• Dholpur-Bharatpur
• Question not attempted

Walkthrough:

1. What the question is testing: Knowledge of NTCA approvals for new tiger reserves in Rajasthan. The question tests whether the student knows the specific location of the newly approved reserve.
2. Why each wrong choice is wrong:
   • Jodhpur: Has no tiger reserve; the nearest is Ranthambore (Sawai Madhopur).
   • Bikaner: Has no tiger reserve; the Gajner Wildlife Sanctuary is a protected area but not a tiger reserve.
   • Jaipur: Has no tiger reserve; the Jhalana Leopard Safari is a leopard conservation area, not a tiger reserve.
3. Why the correct choice is right: The NTCA granted in-principle approval for Rajasthan's fourth tiger reserve in the Dholpur-Bharatpur region in 2023. This was a major development as it expands tiger habitat into eastern Rajasthan.

Correct answer: Dholpur-Bharatpur

Takeaway: For NTCA-related questions, track new approvals and field office inaugurations—these are the most frequently tested developments.

Example 6 — RPSC 2023

Question: The National Tiger Conservation Authority has recently established a new Tiger Reserve in Rajasthan. In which of the following cities has its first field office been recently opened?

Choices students saw:

• Jodhpur
• Bikaner
• Jaipur
• Dholpur-Bharatpur
• Question not attempted

Walkthrough:

1. What the question is testing: Knowledge of NTCA's administrative expansion—specifically, the location of its first field office in Rajasthan. This is a follow-up to the previous question, testing a different aspect of the same development.
2. Why each wrong choice is wrong:
   • Jodhpur: No NTCA field office established here.
   • Bikaner: No NTCA field office established here.
   • Jaipur: The state capital has forest department offices but not the NTCA field office.
3. Why the correct choice is right: The NTCA established its first field office in Rajasthan at Dholpur-Bharatpur, coinciding with the approval of the new tiger reserve in that region. Field offices are the NTCA's local administrative units.

Correct answer: Dholpur-Bharatpur

Takeaway: Note the sequence of developments—first the approval, then the field office. RPSC may test multiple aspects of the same event across different questions.

PYQ Trends & Patterns

Analysis of the six PYQs reveals distinct patterns in how RPSC frames questions on "Climate, Environment & Disasters Current":

Year-Wise Distribution

The 2023 cluster (3 questions) suggests that RPSC may focus heavily on a single theme in a given year. The 2024 questions show a shift toward Rajasthan-specific initiatives (Aandhi village) alongside national tiger reserve news.

Difficulty Trajectory

The questions have become more specific over time:

• 2021: A relatively straightforward geography-based question (Jaisalmer has minimum VDF).
• 2023: Requires knowledge of exact numbers (44 wetlands) and specific locations (Dholpur-Bharatpur).
• 2024: Tests obscure village names (Aandhi) and precise rankings (third largest tiger reserve).

This trajectory suggests that RPSC is increasing the specificity of its current affairs questions, moving from general knowledge to precise recall.

Factual vs Analytical Split

All six questions are purely factual—they test recall of specific information rather than analytical skills. There are no "which of the following statements is correct/incorrect" questions that require evaluating multiple propositions (though the 2024 tiger reserve question came close). This means:

• Memorization is key: There is no substitute for tracking current affairs systematically.
• Source awareness matters: Questions are drawn from government notifications (wetlands), reports (ISFR), and institutional decisions (NTCA approvals).

Recurring Question Types

1. "Which village/city/district?" (3 questions): Aandhi, Jaisalmer, Dholpur-Bharatpur.
2. "How many?" (1 question): 44 wetlands.
3. "Which statement is correct?" (1 question): Guru Ghasidas-Tamor Pingla ranking.
4. "Where was the first field office opened?" (1 question): Dholpur-Bharatpur.

The dominance of location-based questions suggests that RPSC values spatial awareness—knowing where environmental developments are occurring.

Rajasthan-Specific vs National

The 2:1 ratio in favour of Rajasthan-specific questions confirms that the state-level focus is primary. Even the national questions (ISFR, tiger reserve ranking) have a Rajasthan connection—the ISFR question asked about a Rajasthan district, and the tiger reserve question, while about Chhattisgarh, tests general awareness that could appear in any exam.

What This Means for Preparation

• Prioritize Rajasthan-specific environmental news: Notifications from the Department of Forest, Environment and Climate Change, state-level reports, and village-level initiatives.
• Track NTCA developments: Approvals, field offices, rankings, and new reserves.
• Memorize exact numbers: Wetland counts, forest cover percentages, reserve areas.
• Use official sources: The ISFR, NTCA press releases, and Rajasthan government notifications are the primary sources.

What Else Could Be Asked

Based on the patterns observed in the six PYQs and the official syllabus scope, here are concrete predictions for future RPSC questions:

Flavour Analysis

• Depth Extension: The ISFR question (minimum VDF) can be extended to maximum VDF, total forest cover, or change over time. The wetlands question (total count) can be extended to Ramsar sites, specific wetland features, or threats.
• Lateral Extension: The Aandhi question (zero-waste village) can be extended to other village-level initiatives (water conservation, solar energy, organic farming). The NTCA questions can be extended to MEE scores, tiger population estimates, or corridor conservation.
• Combinatorial Extension: Matching questions that combine wetlands with districts, tiger reserves with states, or villages with initiatives. For example: "Match the following villages with their environmental initiatives."

Common Mistakes & Traps

• Confusing "forest cover" with "recorded forest area": Many students think Rajasthan has 9.6% forest cover (the recorded forest area percentage) when the actual forest cover is only 4.87%. The ISFR measures actual tree canopy, not legal classification.
• Assuming all wetlands are Ramsar sites: Only 2 of Rajasthan's 44 wetlands are Ramsar sites. Students often overestimate the number of internationally recognized wetlands.
• Mixing up tiger reserve rankings: The Guru Ghasidas-Tamor Pingla reserve is the third largest, not the largest or second largest. Students often confuse it with Nagarjunsagar-Srisailam (largest) or Manas (second largest).
• Forgetting that Dholpur-Bharatpur is a proposed reserve: The NTCA gave in-principle approval in 2023, but the reserve is not yet fully operational. Students may think it is already established.
• Attributing the wrong initiative to a village: Aandhi is for zero-waste, Menar for water conservation, Devmali for solar energy. Mixing these up is a common error.
• Ignoring the "Question not attempted" option: In RPSC exams, unattempted questions carry no negative marks. Students should only answer if they are confident; guessing can lead to negative marking.
• Overlooking the year of the report: The ISFR 2019 data is different from ISFR 2021. Students must match the question's year reference with the correct report.
• Assuming all tiger reserves are in the same state: The Guru Ghasidas-Tamor Pingla reserve is in Chhattisgarh, not Madhya Pradesh, even though it borders Madhya Pradesh.

Memory Aids & Mnemonics

Mnemonic 1: "AANDHI = Zero Waste"

Name: The "AANDHI" Acronym

The mnemonic:

• A - Aandhi village
• A - Adopts
• N - No-waste
• D - Decentralized
• H - High-tech
• I - Interventions

What it unlocks: The specific village (Aandhi) and its zero-waste model with green technology.

Worked example: When you see a question about a Rajasthan village transforming to zero-waste with green technology, recall "AANDHI" and the acronym will remind you of the village name and the key features (no-waste, decentralized, high-tech interventions).

Mnemonic 2: "Guru Ghasidas - 3rd Largest"

Name: The "Guru's Third" Story Chain

The mnemonic: Imagine Guru Ghasidas (the saint) sitting on a third throne (third largest), in Chhattisgarh (not Madhya Pradesh), with an area of 2,829 sq km (remember 2-8-2-9 as "two-eight-two-nine" or "28-29" as the year 2028-2029).

What it unlocks: The key facts about Guru Ghasidas-Tamor Pingla Tiger Reserve: third largest, Chhattisgarh, 2,829 sq km.

Worked example: For a question asking about this reserve, recall the story: Guru on third throne in Chhattisgarh with 2,829 sq km. This gives you the ranking, location, and area.

Mnemonic 3: "44 Wetlands - Double Four"

Name: The "Double Four" Rhyme

The mnemonic: "Rajasthan's wetlands, double four / Not one less, not one more."

What it unlocks: The exact number of notified wetlands in Rajasthan (44).

Worked example: When asked "how many wetlands in Rajasthan?" the rhyme "double four" immediately brings 44 to mind.

Mnemonic 4: "Jaisalmer - Zero VDF"

Name: The "Desert District" Association

The mnemonic: Jaisalmer is in the Thar Desert → Deserts have no dense forests → Therefore, Jaisalmer has minimum Very Dense Forest.

What it unlocks: The logical link between Jaisalmer's geography and its forest cover classification.

Worked example: For a question about minimum VDF in Rajasthan, think "desert = no dense forest = Jaisalmer."
