Conclusion Call for integrated, decentralised, and locally tailored heat governance anchored in vulnerability mapping and urban equity.
Introduction With 2024 recorded as the warmest year globally and Indian cities witnessing heatwaves as early as March 2025, thermal extremes have transitioned from anomaly to a recurrent hazard, challenging urban planning, health systems, and equity.
Capacity of Indian cities to respond to prolonged heat events
• Fragmented urban governance: Overlapping jurisdictions between municipal bodies, disaster authorities, and health departments weaken coordinated responses. Eg: NDMA (2023) acknowledged limited city-level integration of heatwave response protocols beyond Ahmedabad.
• Eg: NDMA (2023) acknowledged limited city-level integration of heatwave response protocols beyond Ahmedabad.
• Insufficient early warning systems: City-level meteorological alert systems often fail to integrate real-time humidity and night-time temperatures. Eg: Delhi’s 2022 heat alert failed to predict thermal discomfort zones in informal settlements (IMD-Delhi Urban Observatory)
• Eg: Delhi’s 2022 heat alert failed to predict thermal discomfort zones in informal settlements (IMD-Delhi Urban Observatory)
• Under-prepared public health infrastructure: Urban PHCs lack capacity to manage heatstroke cases and dehydration emergencies. Eg: Jaipur Medical College (2023) saw a 28% rise in heat-related emergency cases with no dedicated ward (MoHFW)
• Eg: Jaipur Medical College (2023) saw a 28% rise in heat-related emergency cases with no dedicated ward (MoHFW)
• Vulnerable informal workforce: Nearly 80% of urban workers lack heat-safe working conditions or staggered work hours. Eg: A 2023 study by IIPH-Hyderabad showed productivity losses of 6% in construction sites during summer (IIPH)
• Eg: A 2023 study by IIPH-Hyderabad showed productivity losses of 6% in construction sites during summer (IIPH)
• Urban heat island effect unaddressed: Dense construction and poor ventilation in slums amplify local temperatures. Eg: Kolkata slums recorded 3°C higher nighttime temperatures than the city average during April 2023 (TERI)
• Eg: Kolkata slums recorded 3°C higher nighttime temperatures than the city average during April 2023 (TERI)
Significance of heat-health action plans (HAPs)
• Structured local response planning: HAPs enable local governments to adopt multi-agency coordination and decentralised mitigation. Eg: Ahmedabad Heat Action Plan (2013), India’s first, reduced heatwave mortality by 61% by 2017 (NRDC Report)
• Eg: Ahmedabad Heat Action Plan (2013), India’s first, reduced heatwave mortality by 61% by 2017 (NRDC Report)
• Public health preparedness: HAPs facilitate staff training, hospital readiness, and pre-positioning of emergency supplies. Eg: Pune HAP (2021) implemented heat response drills in all urban PHCs before peak summer (PCCHH)
• Eg: Pune HAP (2021) implemented heat response drills in all urban PHCs before peak summer (PCCHH)
• Community awareness and outreach: HAPs promote early warnings, hydration tips, and behavioural changes in high-risk areas. Eg: Nagpur’s 2022 plan used local radio and WhatsApp groups for ward-level heat advisories (NDMA)
• Eg: Nagpur’s 2022 plan used local radio and WhatsApp groups for ward-level heat advisories (NDMA)
• Policy continuity and scalability: State-level HAPs embed resilience into urban climate strategies under NPCCHH and Smart Cities. Eg: Odisha’s HAP (2023) integrated into Smart City Mission’s disaster resilience module (MoHFW)

Structure of the Answer:
Introduction Highlight the paradox between numerical expansion and global irrelevance of Indian universities with one striking recent fact.
• Briefly list major reasons for lack of global credibility.
• Outline systemic institutional and governance barriers to quality.
• Propose five high-impact structural reforms to make Indian higher education globally competitive.
Conclusion End with a forward-looking remark on transforming demographic advantage into global knowledge capital.
Introduction India boasts one of the largest higher education systems globally, yet struggles to produce world-class universities. The mismatch between numerical growth and global relevance stems from entrenched systemic and regulatory flaws.
Why Indian universities struggle to build global credibility
• Quantity-driven expansion without quality benchmarks – New universities have proliferated without investing in foundational teaching and research infrastructure.
• Eg: 1074 universities (UGC, Jan 2023), yet none in QS Top 100 (2024).
• Low global academic integration – Absence of international faculty, limited foreign student enrolment, and minimal academic mobility hinder global presence.
• Eg: India hosts <50,000 international students, while UK attracts over 500,000 (UNESCO GEM Report 2024).
• Bureaucratic interference in academic functioning – Delays in appointments and overregulation reduce agility and competitiveness
• Eg: University of Madras has had no Vice Chancellor since Aug 2023 due to UGC–Governor deadlock.
• Inadequate innovation and research ecosystem – R&D output remains low due to underfunding and poor faculty incentives.
• Eg: India spends only 0.66% of GDP on R&D, compared to 4% by China (Economic Survey 2023).
• Lack of liberal education and interdisciplinary focus – Overemphasis on professional degrees stifles creativity and critical thinking.
• Eg: AICTE removed Humanities from B.Tech in 2021, drawing global criticism.
Systemic barriers to quality enhancement
• Faculty shortages and recruitment delays – Teaching standards suffer due to vacant posts and slow appointment processes.
• Eg: 5182 vacant faculty posts in Central Universities as of Oct 2024.
• Excessive regulatory centralisation – UGC’s prescriptive guidelines leave little room for contextual or innovative practices.
• Eg: Overreach via NET, CUET, CBCS undermines academic flexibility.
• Political and ideological interventions – Curricular content and faculty selections are increasingly influenced by state ideology.
• Eg: Resignations at JNU (2022–24) linked to academic interference.
• Weak industry–academia collaboration – Disconnect between university research and real-world applications hampers employability and innovation.
• Eg: Only 10% of Indian patents emerge from higher education institutions (DST Innovation Index 2023).
• Flawed accreditation and ranking systems – Quality measurement remains superficial and prone to manipulation.
• Eg: High NIRF ranks for some poorly-performing colleges expose methodological flaws.
Structural reforms to align with global standards
• Replace UGC with HECI as a modular regulator – Reform regulatory architecture by separating funding, accreditation, and quality standards.
• Eg: Draft HECI Bill (2018) aimed to streamline governance and remove regulatory overlaps.
• Guarantee academic and administrative autonomy – Legal safeguards are needed to protect universities from political and bureaucratic overreach.
• Eg: Tandon Committee (2009) recommended graded autonomy for Central Universities.
• Scale up alumni endowments and CSR funding – Financial independence through private philanthropy enhances global competitiveness.
• Eg: IIT Bombay alumni endowment exceeds ₹300 crore, supporting global labs and scholarships (IITB Foundation 2023).
• Reform faculty appointment and promotion systems – Introduce tenure-track systems and global salary parity to attract top talent.
• Eg: IISc Bengaluru’s tenure model has drawn foreign researchers and improved retention (IISc Report 2023).
• Facilitate global partnerships and joint degrees – Collaborate with reputed foreign universities through joint research, campuses, and curricula.
• Eg: IIT Madras–Zanzibar campus (2023) offers globally recognised degrees with African partners.
Conclusion India’s demographic and institutional scale must now be matched by a commitment to autonomy, innovation, and global openness. Only a structural transformation—not incremental reforms—can unlock Indian universities’ true potential on the world stage.

• List major institutional and structural constraints WHO faces due to financial unpredictability.
• Explain how these constraints disrupt healthcare delivery, disease surveillance, and post-conflict recovery in Global South regions.
Conclusion Suggest the need for diversified, predictable funding and stronger regional health partnerships to reduce external dependency.
Introduction The World Health Organization (WHO), as the apex global health body, is increasingly strained by donor unreliability and geopolitical disruptions—jeopardising its capacity to ensure equitable health responses worldwide.
Institutional constraints in sustaining operations
• Donor dependency and skewed funding: Over 80% of WHO’s funding is voluntary and earmarked, limiting flexibility in crisis allocation. Eg: U.S. aid freeze in 2024–25 led to a projected 20% budget cut, hampering core emergency operations.
• Eg: U.S. aid freeze in 2024–25 led to a projected 20% budget cut, hampering core emergency operations.
• Unpredictable political alignments: Donor disengagement linked to regime changes affects WHO’s long-term planning and coordination. Eg: U.S. exit from WHO disrupted joint surveillance and pandemic preparedness projects globally.
• Eg: U.S. exit from WHO disrupted joint surveillance and pandemic preparedness projects globally.
• Fragmented multilateral authority: WHO lacks enforcement power over member states, leading to poor compliance in global health data sharing. Eg: Delayed COVID-19 reporting by China (2020) revealed gaps in WHO’s monitoring authority (Independent Panel on Pandemic Preparedness, 2021)
• Eg: Delayed COVID-19 reporting by China (2020) revealed gaps in WHO’s monitoring authority (Independent Panel on Pandemic Preparedness, 2021)
• Over-centralisation of expertise: Excessive reliance on partnerships with a few high-capacity nations weakens resilience when such partnerships collapse. Eg: Research pipelines and vaccine data sharing were impacted post-U.S. collaboration freeze in 2024–25.
• Eg: Research pipelines and vaccine data sharing were impacted post-U.S. collaboration freeze in 2024–25.
• Administrative rigidity: Bureaucratic delays and slow disbursal hinder WHO’s rapid emergency responses. Eg: Delayed deployment of emergency medical teams in Sudan due to internal clearance hurdles
• Eg: Delayed deployment of emergency medical teams in Sudan due to internal clearance hurdles
Impact on health systems in vulnerable regions of the Global South
• Collapse of emergency health logistics: Pre-positioning of trauma kits and medicine faces severe disruption. Eg: Gaza Strip saw a halt in trauma care support after U.S. aid suspension (WHO EMRO Brief)
• Eg: Gaza Strip saw a halt in trauma care support after U.S. aid suspension (WHO EMRO Brief)
• Disrupted disease surveillance: Withdrawal affects early warning systems for outbreaks and emerging pathogens. Eg: Cholera and dengue outbreaks in Sudan were inadequately tracked after WHO field surveillance was scaled down (AFP Report, 2025)
• Eg: Cholera and dengue outbreaks in Sudan were inadequately tracked after WHO field surveillance was scaled down (AFP Report, 2025)
• Impaired health infrastructure recovery: post-conflict rebuilding of hospitals is suspended or stalled. Eg: Yemen’s rural clinics lost international rehabilitation support after WHO’s funding cutbacks.
• Eg: Yemen’s rural clinics lost international rehabilitation support after WHO’s funding cutbacks.
• Reduced training of health personnel: WHO’s field training and emergency medical team programs shrink due to staffing cuts. Eg: Emergency team training in Eastern Mediterranean region cancelled in 2025 (WHO Regional Update)
• Eg: Emergency team training in Eastern Mediterranean region cancelled in 2025 (WHO Regional Update)
• Equity gaps in vaccine and drug access: Vulnerable regions lose access to WHO-facilitated procurement mechanisms. Eg: HIV treatment delivery in Indian tribal districts affected after USAID shutdown
• Eg: HIV treatment delivery in Indian tribal districts affected after USAID shutdown
Conclusion The fragility of WHO’s funding architecture exposes the Global South to cascading health risks. Strengthening mandatory contributions, promoting South-South cooperation, and insulating global health governance from political flux are now urgent imperatives.

Conclusion Assert the urgency of placing nitrogen management on par with carbon targets to ensure climate-resilient, healthy and sustainable development.
Introduction
While global efforts centre around carbon dioxide, nitrous oxide (N₂O) is over 300 times more potent as a greenhouse gas and has remained under-addressed in climate policy, despite posing multi-sectoral threats.
The paradox: Nitrogen crisis and carbon-centric climate focus
• Higher warming potential ignored: N₂O has a Global Warming Potential (GWP) of 273–300 times CO₂ over a 100-year period but receives less policy attention. Eg: UNEP Global Nitrous Oxide Assessment 2024 warned that N₂O is responsible for 10% of global warming since the Industrial Revolution.
• Eg: UNEP Global Nitrous Oxide Assessment 2024 warned that N₂O is responsible for 10% of global warming since the Industrial Revolution.
• Climate finance and treaties carbon-focused: International climate frameworks under UNFCCC prioritise CO₂ mitigation, with limited provisions for reactive nitrogen. Eg: Paris Agreement focuses on CO₂ but has no specific targets for N₂O emission reduction, despite its rising share in emissions.
• Eg: Paris Agreement focuses on CO₂ but has no specific targets for N₂O emission reduction, despite its rising share in emissions.
• Lack of public discourse and data: Nitrogen-related emissions lack visibility due to poor monitoring, unlike CO₂ which is widely tracked. Eg: The Indian Nitrogen Assessment 2010 remains the last detailed sectoral estimate, showing 70% N₂O emissions from agriculture.
• Eg: The Indian Nitrogen Assessment 2010 remains the last detailed sectoral estimate, showing 70% N₂O emissions from agriculture.
Climate and health risks from excess reactive nitrogen
• Stratospheric ozone depletion: N₂O is the largest ozone-depleting substance emitted today, replacing CFCs in impact. Eg: WMO Ozone Assessment 2022 identified N₂O as a key threat to ozone recovery, with emissions rising from fertiliser use.
• Eg: WMO Ozone Assessment 2022 identified N₂O as a key threat to ozone recovery, with emissions rising from fertiliser use.
• Formation of tropospheric ozone and acid rain: Nitrogen oxides (NOx) from fossil combustion react to form ozone and nitric acid, damaging ecosystems. Eg: Delhi’s NO₂ levels, linked to vehicular emissions and stubble burning, worsen ground-level ozone and acid rain risks (CPCB 2023).
• Eg: Delhi’s NO₂ levels, linked to vehicular emissions and stubble burning, worsen ground-level ozone and acid rain risks (CPCB 2023).
• Airborne health hazards: N₂O and NOx increase respiratory illnesses, particularly among urban poor and children. Eg: A 2023 BMJ study linked over 2.18 million annual deaths in India to air pollution, with nitrogen compounds being significant contributors.
• Eg: A 2023 BMJ study linked over 2.18 million annual deaths in India to air pollution, with nitrogen compounds being significant contributors.
• Aquatic eutrophication and dead zones: Runoff of excess nitrates causes algal blooms, depleting oxygen and killing aquatic life. Eg: The Gulf of Mexico’s dead zone is a textbook case of fertiliser-driven eutrophication, now visible in Indian inland lakes too (NIHFW 2022).
• Eg: The Gulf of Mexico’s dead zone is a textbook case of fertiliser-driven eutrophication, now visible in Indian inland lakes too (NIHFW 2022).
• Soil degradation and acidification: Over-application of urea lowers soil pH and microbial diversity, reducing long-term productivity. Eg: ICAR study (2022) shows acidification in Punjab and Haryana soils, threatening cereal productivity and sustainability.
• Eg: ICAR study (2022) shows acidification in Punjab and Haryana soils, threatening cereal productivity and sustainability.
Multi-sectoral roadmap for mitigation in India
• Shift to balanced fertiliser use: Promote nitrogen-phosphorus-potassium (NPK) balance instead of urea-dominated subsidy system. Eg: Tandon Committee on Fertiliser Use Efficiency (2016) recommended rationalising urea subsidy and incentivising crop-specific blends.
• Eg: Tandon Committee on Fertiliser Use Efficiency (2016) recommended rationalising urea subsidy and incentivising crop-specific blends.
• Enhance nitrogen use efficiency (NUE): Invest in nano-urea, neem-coated urea, and slow-release formulations to reduce excess application. Eg: IFFCO’s nano-urea rollout in 2021 reduced urea demand by 10–15% per hectare, improving NUE .
• Eg: IFFCO’s nano-urea rollout in 2021 reduced urea demand by 10–15% per hectare, improving NUE .
• Incentivise legume cultivation: Restore cereal-legume balance to reduce external nitrogen dependence through biological nitrogen fixation. Eg: National Food Security Mission (NFSM) includes pulses, but needs revamp to shift focus to soil-restorative legume cycles.
• Eg: National Food Security Mission (NFSM) includes pulses, but needs revamp to shift focus to soil-restorative legume cycles.
• Set national reactive nitrogen targets: Establish quantifiable N₂O limits through a National Nitrogen Policy, integrated with climate goals. Eg: FAO’s Nitrogen Roadmap 2023 recommends country-specific nitrogen budgets for better monitoring and mitigation.
• Eg: FAO’s Nitrogen Roadmap 2023 recommends country-specific nitrogen budgets for better monitoring and mitigation.
• Regulate industrial N₂O emissions: Enforce standards on chemical and nylon industries, where mitigation technologies already exist. Eg: UNEP 2024 report says 40% of industrial N₂O emissions can be abated using existing scrubbing technologies.
• Eg: UNEP 2024 report says 40% of industrial N₂O emissions can be abated using existing scrubbing technologies.
• Improve wastewater nitrogen recovery: Promote sewage treatment plants with nitrogen recovery, especially in urban clusters. Eg: Bengaluru’s Jakkur Lake STP uses constructed wetlands to recover and reuse nitrogen for aquaculture .
• Eg: Bengaluru’s Jakkur Lake STP uses constructed wetlands to recover and reuse nitrogen for aquaculture .
• Integrate nitrogen into air pollution strategies: Link NOx control under NCAP with climate and nitrogen strategies to achieve co-benefits. Eg: National Clean Air Programme (NCAP) covers 122 cities, but lacks explicit nitrogen component, despite overlapping goals.
• Eg: National Clean Air Programme (NCAP) covers 122 cities, but lacks explicit nitrogen component, despite overlapping goals.
Conclusion As India advances towards net-zero by 2070, reactive nitrogen must enter the climate spotlight alongside carbon. A dedicated national nitrogen strategy, integrating agriculture, health, and environment, is now critical for achieving resilient, low-emission growth.

Conclusion Emphasise trophic cascades as a nature-based solution for sustainable restoration and climate resilience.
Introduction The disappearance or return of a single predator can transform entire ecosystems. This systemic ecological phenomenon is known as a trophic cascade, crucial in rebuilding degraded landscapes.
What are trophic cascades in ecology
• Top-down control in ecosystems: Apex predators regulate herbivore populations, influencing multiple trophic levels.
• Chain reactions across food webs: The effects ripple down to plants, soil, and even microbial life.
• Non-linear ecological effects: Changes in predator density can lead to disproportionate responses in lower trophic levels.
• Influence on species behaviour: Presence of predators alters prey behaviour, reducing overgrazing in sensitive areas.
• Scientific basis from empirical studies: Proven through field experiments and rewilding initiatives globally. Eg: James Estes’ sea otter studies (1970s) showed that predator loss caused urchin overgrazing and kelp forest collapse in Alaska (Estes et al., Science, 2011)

Significance in ecosystem restoration
• Revives vegetation structure: Predators reduce herbivore pressure, enabling plant regeneration. Eg: Wolves in Yellowstone (1995) led to aspen, cottonwood and willow recovery due to reduced elk browsing (US NPS)

• Boosts biodiversity: New vegetation supports a range of species including birds, insects and mammals. Eg: Beaver and songbird return post-wolf reintroduction in Yellowstone enhanced ecosystem richness (Ecology Letters, 2012)
• Eg: Beaver and songbird return post-wolf reintroduction in Yellowstone enhanced ecosystem richness (Ecology Letters, 2012)
• Restores hydrology and soils: More vegetation stabilises soils, improves water retention, and reduces erosion. Eg: Yellowstone riverbanks saw better water retention and riparian recovery after trophic regulation (PLOS Biology, 2014)
• Eg: Yellowstone riverbanks saw better water retention and riparian recovery after trophic regulation (PLOS Biology, 2014)
• Aids climate resilience: Vegetation recovery from cascades increases carbon sinks and buffers climate stress. Eg: Rewilding Scotland with native predators shows increased peatland vegetation, a major carbon store (Rewilding Europe Report, 2023)
• Eg: Rewilding Scotland with native predators shows increased peatland vegetation, a major carbon store (Rewilding Europe Report, 2023)
• Reduces human-wildlife conflict: Balanced ecosystems reduce abnormal animal behaviour like crop raiding. Eg: Predator return in Gorongosa, Mozambique reduced overgrazing and human-animal conflict
• Eg: Predator return in Gorongosa, Mozambique reduced overgrazing and human-animal conflict
Conclusion Trophic cascades reveal the deep interconnections in nature. Protecting predator species is not just conservation—it is ecological engineering that revives nature’s own ability to heal.

Q7. Attitudes are not just internal dispositions but tools of moral and political influence. Discuss. How do they mediate between value systems and public conduct? (10 M)
Difficulty Level: Medium
Reference: InsightsIAS
Why the question: To examine the ethical function of attitudes beyond psychology, particularly in shaping governance, moral leadership, and civic behaviour in society. Key Demand of the question: Explain how attitudes influence moral and political environments, and analyse how they translate internal value systems into real-world behaviour and public ethics. Structure of the Answer: Introduction Define attitude in ethical context and link it briefly to moral and political conduct. Body Show how attitudes act as tools for moral and political influence through leadership, public opinion, and symbolic gestures. Explain how attitudes mediate between personal values and actual behaviour in administration and public service. Conclusion Highlight the need to institutionalise ethical attitudes in governance to sustain democratic morality.

Conclusion Highlight the need to institutionalise ethical attitudes in governance to sustain democratic morality.
Introduction Attitudes are mental predispositions shaped by values, but they also guide leadership styles, influence mass behaviour, and sustain ethical governance in democratic societies.
Attitudes as tools of moral and political influence
• Framing ethical leadership: Attitudes shape how leaders respond to moral challenges in public life. Eg: Dr. A.P.J. Abdul Kalam’s service-mindedness instilled ethical inspiration among youth and civil servants.
• Eg: Dr. A.P.J. Abdul Kalam’s service-mindedness instilled ethical inspiration among youth and civil servants.
• Mobilising civic participation: Political attitudes can transform moral concerns into democratic action. Eg: 2011 Anti-Corruption movement channelled widespread moral discontent into support for the Lokpal Bill.
• Eg: 2011 Anti-Corruption movement channelled widespread moral discontent into support for the Lokpal Bill.
• Setting institutional tone: Ethical attitudes in top officials influence entire systems. Eg: T.N. Seshan’s assertive attitude as CEC brought electoral discipline and citizen confidence in the 1990s.
• Eg: T.N. Seshan’s assertive attitude as CEC brought electoral discipline and citizen confidence in the 1990s.
• Combating polarisation: Constructive political attitudes reduce ethical toxicity in discourse. Eg: Dr.Manmohan Singh’s parliamentary decorum reflected a value-driven attitude promoting institutional respect.
• Eg: Dr.Manmohan Singh’s parliamentary decorum reflected a value-driven attitude promoting institutional respect.
• Expressing symbolic resistance: Moral attitudes are externalised through ethical public gestures. Eg: Gandhi’s Salt March (1930) used non-violence as an attitudinal message of protest against colonial injustice.
• Eg: Gandhi’s Salt March (1930) used non-violence as an attitudinal message of protest against colonial injustice.
Mediating between value systems and public conduct
• Converting values into action: Attitudes provide the behavioural link between internal ethics and decision-making. Eg: IAS officer Armstrong Pame’s road project in Manipur showed proactive public service rooted in empathy.
• Eg: IAS officer Armstrong Pame’s road project in Manipur showed proactive public service rooted in empathy.
• Safeguarding moral consistency: Strong attitudes ensure conduct remains value-aligned under pressure. Eg: Ashok Khemka’s repeated resistance to illegal orders reflects integrity-driven administrative conduct.
• Eg: Ashok Khemka’s repeated resistance to illegal orders reflects integrity-driven administrative conduct.
• Aligning roles with constitutional ethics: Attitudes help officials act in sync with their moral and legal duties. Eg: Police officers ensuring fair trial processes during riots embody Article 21–based ethical attitudes.
• Eg: Police officers ensuring fair trial processes during riots embody Article 21–based ethical attitudes.
• Influencing institutional culture: Ethical attitudes at the top inspire wider ethical compliance. Eg: E. Sreedharan’s punctuality in Delhi Metro created a disciplined work ethic among subordinates.
• Eg: E. Sreedharan’s punctuality in Delhi Metro created a disciplined work ethic among subordinates.
• Bridging formal and informal ethics: Attitudes fill moral voids when law is silent or delayed. Eg: Post-violence in Manipur (2023), community elders adopted peace-building attitudes to restore trust.
• Eg: Post-violence in Manipur (2023), community elders adopted peace-building attitudes to restore trust.
