May 28 is celebrated every year as World Dugong Day.
About Dugongs:
Species Info: Dugong dugon, also known as sea cows, are herbivorous marine mammals closely related to manatees but live only in saltwater.
Habitat: They live in shallow coastal waters and are mainly found in the Andaman and Nicobar Islands, Gulf of Mannar, Palk Bay, and Gulf of Kutch.
Diet and Role: Dugongs feed on seagrass species like Cymodocea, Halophila, Thalassia, and Halodule. As they graze, they stir up the seabed, earning the nickname “farmers of the sea.”
Lifespan and Behaviour: They can live up to 70 years and are usually solitary or seen in mother-calf pairs.
Reproduction: Females mature at 9–10 years and give birth every 3–5 years, resulting in a slow population growth of about 5% per year.
Conservation Concern: India’s dugong population has dropped to an estimated 200 individuals, with shrinking range and numbers.
Conservation Efforts in India:
IUCN Status: Dugongs are listed as ‘Vulnerable’ globally and ‘Regionally Endangered’ in India.
Legal Protection: They are protected under Schedule I of the Wild Life (Protection) Act, 1972.
Global Agreements: India joined the Convention on Migratory Species in 1983 and signed the Dugong Conservation MoU in 2008.
Dugong Reserve: In 2022, India established its first Dugong Conservation Reserve in Palk Bay, Tamil Nadu, covering 448.3 sq. km.
[UPSC 2015] With reference to ‘dugong’ a mammal found in India, which of the following statements is/are correct?
1. It is a herbivorous marine animal. 2. It is found along the entire coast of India. 3. It is given legal protection under Schedule I of the Wildlife (Protection) Act 1972.

[UPSC 2024] What is disaster resilience? How is it determined? Describe various elements of a resilience framework. Also mention the global targets of the Sendai Framework for Disaster Risk Reduction (2015- 2030).
Linkage: The heat health crisis falls under the broader domain of disaster risk reduction and building resilience, especially considering extreme heat events as climate-induced disasters. It prompts discussion on defining resilience and the frameworks needed, aligning with the call for embedding heat resilience into public health systems.
Mentor’s Comment: India is going through a serious climate-health crisis as rising temperatures and frequent heatwaves put more pressure on the already stretched public health system. At the recent national conference “India 2047: Building a Climate-Resilient Future,” experts shared not only scientific facts like wet-bulb temperatures but also the real-life struggles of informal workers. This showed how heat stress and social inequality are closely linked. The conference highlighted the need to move beyond isolated emergency care and take united, cross-sector, and fair action to build climate resilience into the way we manage public health.
Today’s editorial discusses the serious climate-health crisis as rising temperatures and frequent heatwaves. This content would help in GS Paper II ( Governance & Health Sector) and GS Paper III (Climate change impact).

Let’s learn!
Why in the News?
As extreme weather increases, we need to move from only treating emergencies to preventing problems by focusing on fair and caring public health.
Why is linking weather alerts with health systems crucial?
Enables Timely Preventive Action: Early warning systems allow health workers to prepare and respond before heatwaves lead to medical emergencies. Eg: In Ahmedabad, heat alerts trigger distribution of hydration kits and public advisories, reducing heatstrokecases.
Strengthens Community-Level Response: Alerts shared through ASHA workers or local networks can activate door-to-door checks, especially for the elderly and chronically ill. Eg: ASHAs sending WhatsApp messages and visiting vulnerable residents during red alerts.
Reduces Burden on Emergency Healthcare: By preventing illness through early interventions (like avoiding midday work, increasing hydration), the pressure on hospitals and emergency services is reduced. Eg: Pre-monsoon planning with meteorological inputs helps health centers stock cooling kits and prepare treatment spaces.
What is the impact of extreme heat on India’s public health?
Rise in Heat-related Illnesses and Deaths: Extreme heat leads to heatstroke, dehydration, and worsens heart and kidney conditions. Eg: According to the National Centre for Disease Control (NCDC), over 25,000 heat-related deaths were recorded in India between 1992 and 2020.
Overburdened Healthcare Infrastructure: Hospitals face a surge in emergency cases during heatwaves, straining limited resources. Eg: During the 2022 heatwave, Delhi’s Lok Nayak Hospital reported a 30% increase in patients with heat-related symptoms in just a week.
How does extreme heat act as a “social injustice multiplier”?
Greater Risk to Vulnerable Populations: Outdoor workers, elderly, and slum dwellers suffer disproportionately due to poor shelter and exposure. Eg: A study by the Indian Institute of Public Health (Ahmedabad) found construction workers had a 2.5 times higher risk of heat illness compared to the general population during peak summer.
Limited adaptive capacity: Daily wage workers, street vendors, and waste pickers cannot afford to stop working during heatwaves, making them more vulnerable to heat stress and illness. Eg: Construction workers under tin roofs suffer intense heat but have no choice but to continue working.
Excludes the marginalised from public guidance: Advice like “stay indoors” or “avoid exertion” is often irrelevant to those who lack shelter, depend on outdoor jobs, or live in overcrowded spaces, highlighting deep systemic inequalities. Eg: A homeless person or a street vendor cannot follow “stay indoors” guidance during a red alert.
Who can act as frontline heat-safety champions?
ASHA Workers and Primary Health Workers: Trained Accredited Social Health Activists (ASHAs) and staff at Primary Health Centres (PHCs) are well-placed to spread awareness, monitor vulnerable groups, and respond early to heat-related illnesses. Eg: An ASHA worker in a rural village sends heat alerts via WhatsApp and conducts door-to-door visits during a heatwave.
Health and Wellness Centre Staff: Staff at Health and Wellness Centres can play a key role in educating communities, distributing hydration kits, and advising on preventive measures like staying hydrated and avoiding midday sun. Eg: A nurse at a wellness centre trains local youth on recognizing signs of heat stress and first-aid response.
What are the steps taken by the Indian Government?
Development of Heat Action Plans (HAPs): The government, in collaboration with local bodies and NGOs, has promoted city-level Heat Action Plans to reduce heat-related mortality through early warnings, public awareness, and cooling strategies. Eg: The Ahmedabad Heat Action Plan (2013) includes early warning systems, public cool spaces, and training for health workers.
Integration with Meteorological Services: India Meteorological Department (IMD) provides heat alerts, which are increasingly being integrated into local health response systems to trigger preventive action. Eg: Heat alerts in Odisha are linked to ASHA worker messaging and hydration kit distribution before peak summer.
Policy Push for Climate-Resilient Health Systems: The National Action Plan on Climate Change and Human Health (NAPCCHH) encourages health systems to be climate-ready by building infrastructure, developing clinical protocols, and training staff. Eg: Health ministries now issue advisories on heat stress, including guidance on modifying medication for chronic patients during heatwaves.
What preventive steps can make India’s health system heat-resilient? (Way forward)
Strengthening Primary Health Infrastructure: Equip primary health centres, Health & Wellness Centres, and ASHA workers with training and protocols to identify and respond to heat-related illnesses. Eg: Trained ASHA workers in rural Gujarat conduct door-to-door checks during heat alerts and share hydration tips via WhatsApp groups.
Integrating Heat Risk into Chronic Disease Care: Clinicians should adjust medications, provide heat safety counselling, and track high-risk patients like those with heart or kidney conditions during summer. Eg: In Delhi, doctors monitor diabetic patients more closely during red alerts and advise them on avoiding midday exposure.
Standardising Clinical Protocols for Heat Illness: Create and implement national clinical guidelines for diagnosing and treating heatstroke and heat stress, including summer drills and heat corners in hospitals. Eg: Rajasthan hospitals now stock cooling kits and have designated heat response units during summer months.

Representation of the People Act (RPA), 1951 is an area that aspirants commonly skip or read superficially. A lack of analysis of the legal provisions is the primary reason. This article takes a focused approach on such a provision: candidates contesting from multiple constituencies—a topic often relegated to the margins of preparation. From case examples like Narendra Modi contesting from Varanasi and Vadodara in 2014, to critical issues like the high financial cost of by-elections (₹130 crore projected for 2024), the article bridges the gap between core provisions and their practical implications. The Back2Basics section, curated specifically for aspirants seeking a competitive edge, ensures you can effectively link multi-dimensional impacts like electoral fairness with UPSC GS-2 themes.
PYQ ANCHORING & MICROTHEMES:
GS 2 : Discuss the procedures to decide the disputes arising out of the election of a Member of the Parliament or State Legislature under The Representation of the People Act, 1951. What are the grounds on which the election of any returned candidate may be declared void? What remedy is available to the aggrieved party against the decision? Refer to the case laws. [2022]
GS 2: On what grounds a people’s representative can be disqualified under the Rep resentation of People Act, 1951? Also mention the remedies available to such person against his disqualification. [2019]
Microtheme: Representation of Peoples Act
In India, candidates are permitted to contest elections from more than one constituency. While this practice is commonly used by political parties as a strategy to maximize their chances of winning, it carries significant legal, financial, and democratic implications.
Political Motivations Behind Contesting from Multiple Constituencies
Motivation
Explanation
Specific Example
Strategic Advantage
Candidates hedge their chances by contesting from multiple constituencies, reducing the risk of total loss.
Narendra Modi (2014): Contested and won from Varanasi (Uttar Pradesh) and Vadodara (Gujarat), ensuring a seat despite possible regional uncertainties.
Resource Mobilization
Ruling party candidates utilize party resources effectively across constituencies to dominate electoral competition.
Indira Gandhi (1980): Contested from Rae Bareli and Medak, leveraging Congress’s vast organizational resources to secure wins in diverse regions.
Demonstrating Party Strength
Contesting in multiple regions highlights the party’s influence and nationwide appeal, enhancing its image and sway over voters.
Rahul Gandhi (2019): Contested from Wayanad (Kerala) and Amethi (Uttar Pradesh) to demonstrate Congress’s reach from North to South India.
Perception of Legitimacy
Winning from multiple seats boosts the candidate’s image as a national leader, gaining internal party clout and voter trust.
Sonia Gandhi (1999): Contested from Bellary (Karnataka) and Amethi (Uttar Pradesh), emphasizing her leadership’s credibility and consolidating voter support.
Provisions of the RPA, 1951 Related to Multiple Constituencies
Section 33(7):
This section permits a person to contest elections from up to two constituencies simultaneously for Lok Sabha or Vidhan Sabha (State Assembly) elections.
This provision was introduced in 1996 through an amendment (Representation of the People (Amendment) Act, 1996) to reduce the burden of by-elections, as candidates earlier could contest from more than two constituencies.
Vacating Seats in Case of Winning Multiple Constituencies:
If a candidate contests from two constituencies and wins both, Section 70 of the RPA, 1951, mandates that the individual can hold only one seat.
The candidate must submit their resignation from the other constituency, which triggers a by-election in that seat.
Deposit Requirement:
Under Section 34, candidates are required to deposit a certain amount of money as a security fee while filing their nomination.
While this aims to deter frivolous nominations, it does not specifically restrict candidates from contesting multiple seats.
Key Challenges and Loopholes in the Provisions
Cost of By-Elections: While the RPA acknowledges the resignation requirement, it does not provide measures to mitigate the significant cost of holding by-elections after a candidate vacates a seat.
For example, the administrative cost of the 2014 general elections was ₹3,870 crore, projected to rise to ₹6,931 crore in 2024. If multiple candidates win from two constituencies, the extra cost for holding by-elections can amount to around ₹130 crore.
No Restriction on Strategic Contesting: The Act does not address strategic contests where political parties field high-profile leaders in multiple constituencies to bolster their chances of winning more seats.
Limited Safeguards Against Voter Disenfranchisement: Although a candidate vacates one seat, there are no safeguards in the RPA to ensure continued accountability for constituents in the vacated constituency.
Way Forward
To address the issue of candidates contesting from multiple constituencies in India, here are practical solutions:
Change the Law: Amend the Representation of the People Act, 1951, to prevent candidates from contesting more than one seat at a time. This will reduce unnecessary by-elections and save public money.
Introduce Financial Responsibility: Make candidates pay a fixed amount, such as ₹5 lakh, if they win in multiple constituencies and vacate a seat. This ensures accountability for the additional costs of by-elections.
Empower the Election Commission: Strengthen the Election Commission’s authority to strictly monitor electoral conduct, enforce laws, and handle grievances efficiently.
Promote Party-Level Reforms: Encourage political parties to adopt transparent candidate selection processes based on merit and local voter preferences, rather than favoritism or strategy alone. This ensures better representation.
The practice of contesting from multiple constituencies, while legally permissible, raises questions about the balance between electoral strategy and democratic fairness. Addressing these challenges requires a reevaluation of the rules to ensure transparency, equitable representation, and accountability in the electoral process.
#BACK2BASICS: Impact of Contesting from Multiple Constituencies on Electoral Fairness
Component of Electoral Fairness
Impact of Multiple Constituencies
Example
Equal Representation
Undermines representation as resources and attention may favour high-profile candidates over local needs.
Kuldip Nayar vs Union of India (2006): Affirmed equal representation as a democratic principle.
Transparent Electoral Processes
Leads to voter confusion and administrative burden in managing by-elections, affecting transparency.
Election Commission’s Reports on By-Elections: Highlight the complexity and resource strain caused by vacated seats.
Free and Equal Competition
Favors dominant parties that can afford expensive campaigns across multiple constituencies, limiting smaller parties.
EC’s Model Code of Conduct emphasizes a level playing field.
Voter Inclusion and Accessibility
Creates disenfranchisement when voters feel neglected due to candidates vacating seats after winning.
Voter discontent highlighted during the 2014 and 2019 elections when leaders vacated multiple seats.
Accountability and Rule of Law
Raises questions on accountability as leaders vacate one seat, impacting the constituents’ trust in representation.
Supreme Court Observation (2014): Criticized lack of measures to address frequent by-elections stemming from multi-seat contests.
In 2024, a soundtrack was released inspired by the Laschamps event, a magnetic flip-flop that occurred 41,000 years ago when Earth’s magnetic field weakened to just 5% and the poles briefly reversed.
What is Magnetic Flip-Flop?
Definition: A magnetic flip-flop is when Earth’s magnetic poles reverse, with the north and south poles switching places.
Magnetic Field Source: Earth’s magnetic field is generated by the movement of molten iron in the outer core, acting like a giant magnet.
Reversal Types:
A long-term change is called a geomagnetic reversal.
A short-lived, temporary switch is a geomagnetic excursion.
Field Behavior: During a reversal, the magnetic field weakens significantly and the direction of field lines flips.
Occurrence: These events are irregular and unpredictable.
Recent Magnetic Reversals and Excursions:
Last Major Reversal: The Brunhes–Matuyama reversal occurred about 780,000 years ago.
Known Excursions:
Norwegian-Greenland Sea event (~64,500 years ago)
Laschamps excursion (~41,000 years ago), when field strength dropped to 5% of today’s level
Mono Lake excursion (~34,500 years ago)
Indian Evidence: Excursions found in Uttarakhand (Bagwalipokar), dated to 15,500–14,700 years and 8,000–2,850 years ago.
Pole Movement: Since 1831, the north magnetic pole has shifted 1,100 km toward Siberia and now moves at 35 km/year, while the south pole is more stable.
Implications of Magnetic Flip-Flop:
Radiation Exposure: A weaker magnetic field during flip-flop allows more cosmic radiation, affecting:
Satellites and astronauts
Navigation and communication systems
Power grids and electronics
Protective Shield: Earth’s atmosphere still protects against harmful radiation even when the magnetic field is weak.
Climate & Ozone Effects: Events like Laschamps may have altered the ozone layer and climate, but no confirmed link to mass extinctions.
South Atlantic Anomaly: A current weak-field region affecting spacecraft over South America and South Africa.
Monitoring Tools: Scientists use satellites, ice cores, volcanic rocks, and geomagnetic observatories to track field changes.
Global Guidance: The World Magnetic Model, updated every 5 years, supports navigation systems worldwide.
Prediction Outlook: Though timing of future reversals is uncertain, computer models and cosmic data are improving forecasts.
[UPSC 2017] Consider the following statements:
1. The Earth’s magnetic field has reversed every few hundred thousand years.
2. When the Earth was created more than 4000 million years ago, there was 54% oxygen and no carbon dioxide.
3. When living organisms originated, they modified the early atmosphere of the Earth.
Which of the statements given above is/are correct?

Scientists have discovered a new sea creature from the Cambrian period named Mosura fentoni, found in Canada’s Burgess Shale, one of the most important fossil sites in the world.
About Mosura fentoni:
Discovery Site: Mosura fentoni was discovered in Canada’s Burgess Shale, a well-known Cambrian fossil site.
Biological Group: It belongs to radiodonts, an extinct group of marine predators related to insects, crabs, and spiders.
Size and Structure: The creature is very small (1.5 to 6 cm) but has a long, complex body made of 26 segments.
Body Zones:
The neck supports the head.
The mesotrunk has six paddle-shaped flaps for swimming, like mini propellers.
The posterotrunk has up to 16 segments with rows of thin gills and small flaps.
Breathing Adaptation: The gills in the posterotrunk likely acted as a breathing zone, similar to the tails of horseshoe crabs that help collect oxygen.
Evolutionary Importance:
Arthropod Evolution: The find helps explain how early arthropods (like modern insects and crustaceans) evolved diverse forms.
Advanced Abilities: Despite its small size, M. fentoni had specialised swimming and breathing systems.
Evolutionary Position: It is placed near the base of the hurdiid family in the radiodont family tree.
Segment Specialisation: Its body shows early examples of segment division for specific tasks — a trait common in modern arthropods.
Key Insight: The discovery suggests that complex body planning in arthropods began much earlier than previously thought.
Back2Basics: Cambrian Period:
The Cambrian Period is a division of the geologic time scale that lasted from approximately 541 million to 485 million years ago.
It is the first period of the Paleozoic Era and follows the Precambrian Eon.
It is significant because it marks a time when most major animal groups first appeared in the fossil record.
This period is characterized by the development of complex, multicellular life, especially in marine environments.
The Cambrian Explosion refers to a relatively short evolutionary event—occurring around 541 million years ago—during which a vast number of new animal species and body plans rapidly emerged.
Within about 20 to 25 million years, nearly all major animal phyla (like arthropods, mollusks, and chordates) appeared.
This explosion of biodiversity is seen as one of the most important evolutionary events in Earth’s history.

The Secretary General of the Rajya Sabha acts as the chief executive and administrative head of the Rajya Sabha Secretariat.
Researchers have solved the genetic mysteries behind Mendel’s Experiments on Inheritance, using advanced DNA sequencing and genome analysis.
About Mendel’s Experiments on Inheritance:
Who Was Mendel: Gregor Mendel was an Austrian monk who studied pea plants starting in 1856 to find out how traits like height or color are passed from parents to children.
Years of Study: He worked for 8 years and tested over 10,000 plants. His results were shared in 1865 but ignored at the time.
Rediscovered Later: In 1900, other scientists realised how important Mendel’s work was.
What He Studied: He looked at 7 traits in peas – Seed shape, seed colour, flower colour, pod shape, pod colour, flower position, and plant height.
What He Found: Some traits (like round seeds) are stronger than others (like wrinkled seeds). These stronger traits usually show up in the next generation.
Why It Matters: Mendel showed that traits are passed through tiny units called genes, and each gene can have different versions called alleles. This became the foundation of genetics.
What the Study Found (2024):
What Scientists Did: In April 2024, scientists studied the DNA of 697 types of pea plants to understand the exact genes behind all 7 traits that Mendel studied.
Big Data: They used powerful machines to look at a huge amount of data — as much as 14 billion pages of information!
Surprising Results: They found that the pea plant family is more mixed than expected, with 8 different genetic groups due to crossbreeding.
New Genetic Details:
Pod color changes due to a missing piece of DNA.
Pod shape is controlled by 2 specific genes.
Flower position changes with a small DNA change.
More Than Mendel: They also found 72 other traits related to seeds, pods, leaves, and roots.
Why It’s Useful: These findings can help farmers grow better crops, protect plants from diseases, and prepare for climate change.
