Climate Change as a Public Health Emergency

Source: TH

Subject: Climate Change

Context: The health experts including warned that climate change has transitioned from an environmental threat to a full-blown medical emergency in India.

About Climate Change as a Public Health Emergency:

What is Climate Change?

• Climate change refers to long-term shifts in temperatures and weather patterns, primarily driven by human activities like burning fossil fuels, which release greenhouse gases.

Key Data and Stats:

• Extended Disease Windows: In Delhi-NCR, the peak for Dengue has shifted from September to November due to prolonged warm and rainy cycles.
• Geographic Expansion: Malaria is now being reported in cooler, high-altitude regions like Himachal Pradesh, where it was historically non-existent.
• Pollution Impact: Higher energy demand for cooling has increased PM2.5 levels, microscopic pollutants that damage the lungs, heart, and kidneys.
• Heat Mortality: Rising nighttime temperatures in cities like Mumbai and Delhi are eliminating the human body’s recovery window, leading to a surge in heat-stroke-related deaths.

Factors Raising Climate Change Concerns:

• Urban Heat Island Effect: Cities trap heat due to concrete structures, leading to dangerously high nighttime temperatures.
• Sanitation Overload: Frequent urban flooding (e.g., in Mumbai) overwhelms drainage, causing outbreaks of Cholera and Typhoid.
• Feedback Loops: Increased use of air conditioning to combat heat leads to higher emissions, which in turn traps more heat in the atmosphere.
• Water Scarcity: Prolonged droughts force rural communities to use unsafe water sources, rising the burden of diarrhoeal diseases.
• Agricultural Disruption: Unseasonal rains and heat stress reduce crop yields and the nutritional quality of food, leading to chronic malnutrition.

Implications of the Health Crisis:

• Vector-Borne Surge: Mosquitoes are migrating to newer territories, exposing populations with no prior immunity to Malaria and Zika.
• Chronic Organ Damage: PM2.5 pollutants penetrate the bloodstream, accelerating atherosclerosis and increasing the risk of stroke and heart attack.
• Maternal and Infant Risks: Extreme heat exposure is now scientifically linked to preterm births and low birth weight in newborns.
• Renal Stress: Chronic dehydration and heat stress are contributing to a silent rise in Chronic Kidney Disease (CKD) among outdoor manual laborers.
• Food & Milk Insecurity: Heat stress in cattle reduces milk production, directly compromising the nutrition of infants and growing children.

Way Ahead:

• Climate-Resilient Healthcare: Upgrading hospital infrastructure to handle surge capacity during extreme heatwaves and floods.
• Early Warning Systems: Using meteorological data to predict disease outbreaks and issuing health alerts to vulnerable outdoor workers.
• Urban Greening: Implementing Cool Roof technologies and increasing urban forest cover to mitigate the heat island effect.
• Clean Energy Transition: Reducing reliance on fossil fuels for cooling to break the emission-heat feedback loop.
• Nutritional Safeguards: Developing heat-resistant crop varieties and supporting dairy farmers to maintain food security during climate shocks.

Conclusion:

Climate change is no longer a distant environmental forecast; it is a present-day medical crisis that is quietly redrawing the health map of India. Treating this as a purely ecological issue overlooks the profound human cost, from impaired infant health to the expansion of deadly infections. Recognizing it as a public health emergency is the essential first step toward building a resilient India capable of surviving a warming planet.

India First Fast Breeder Reactor (FBR) Achieve Criticality

Source: NDTV

Subject: Science and Technology

Context: Prime Minister of India congratulated scientists as India’s first indigenous Prototype Fast Breeder Reactor (PFBR) at Kalpakkam, Tamil Nadu, successfully attained criticality.

About India First Fast Breeder Reactor (FBR) Achieve Criticality:

What is Fast Breeder Reactor (FBR)?

• A Fast Breeder Reactor is an advanced nuclear reactor that generates more fissile material (fuel) than it consumes while producing electricity. It is fast because it uses high-energy (fast) neutrons to sustain the fission chain reaction, unlike conventional reactors that use slow neutrons.

What is Criticality?

• In nuclear physics, criticality is the state in which a nuclear fuel sustains a self-supporting chain reaction. It is the point at which the number of neutrons produced by fission is exactly equal to the number of neutrons lost (through leakage or absorption) plus those causing new fissions.

Developed By: The 500 MWe PFBR has been developed by Bharatiya Nabhikiya Vidyut Nigam Ltd (BHAVINI).

How It Works?

1. Fuel: It uses a Uranium-Plutonium Mixed Oxide (MOX) fuel.
2. The Breeding Process: The reactor core is surrounded by a blanket of fertile material (Uranium-238). When these U-238 atoms capture fast neutrons, they undergo transmutation to become Plutonium-239, which is a high-grade nuclear fuel.
3. Coolant: Instead of water, it uses Liquid Sodium as a coolant because sodium does not slow down neutrons, allowing the fast reaction necessary for breeding.
4. Heat Exchange: The heat generated by fission is transferred to the liquid sodium, which then heats water to produce steam to turn turbines.

Aim:

• To create a surplus of Plutonium fuel to power future fast reactors.
• To act as a bridge to the third stage of India’s nuclear programme, where Thorium-232 will be converted into Uranium-233.
• To provide a sustainable, long-term solution to India’s energy needs by extracting significantly more energy from uranium than conventional reactors.

Key Features:

• Indigenous Design: Built almost entirely with Indian technology and materials.
• MOX Fuel Technology: Utilizes recycled fuel from the first stage (Pressurized Heavy Water Reactors).
• Passive Safety: Equipped with advanced safety systems that can automatically shut down the reactor during emergencies without human intervention.
• High Efficiency: Operates at higher temperatures than conventional reactors, leading to better thermal efficiency.

Significance:

• Attaining criticality is the final scientific green light before the reactor begins generating electricity for the grid.
• It proves that the reactor’s core geometry, fuel arrangement, and engineering calculations are accurate and functional.
• For India, PFBR criticality signals the formal operational start of the Second Stage of its nuclear roadmap, moving the country closer to utilizing its vast thorium reserves.

Internet Protocols

Source: TH

Subject: Science and Technology

Context: A study of six major Indian ISPs reveals a haphazard and inconsistent internet censorship regime, where only 1,414 out of 43,083 blocked domains were restricted across all providers.

About Internet Protocols:

What It Is?

• An Internet Protocol (IP) is a set of rules that govern how data is sent and received over the internet. Much like a postal system, it ensures that packets of digital information are addressed correctly and delivered to the right destination.

How It Works?

When you access a website, your request is broken down into small data packets.

1. Addressing: Each packet is given an IP address (source and destination).
2. Routing: Routers and switches use these protocols to determine the most efficient path for the packets across various networks.
3. Reassembly: Once the packets reach the destination, the protocols ensure they are put back together in the correct order to display the webpage or file.

Common Types of Protocols:

• DNS (Domain Name System): The phonebook of the internet. It translates human-readable names into machine-readable IP addresses.
• HTTP/HTTPS (Hypertext Transfer Protocol): The foundation of data exchange on the web; the ‘S’ stands for secure (encrypted).
• TLS (Transport Layer Security): Provides authentication and encryption to ensure that the data being transferred remains private.
• TCP (Transmission Control Protocol): Works with IP to ensure that data is delivered reliably and in the correct sequence.

Internet Censorship in India:

Legal Framework

• IT Act, 2000: Section 69A empowers the Central Government to issue blocking orders in the interest of national sovereignty, integrity, defense, or public order. Section 79 provides the framework for intermediaries (like ISPs) to follow these directions.
• Licensing Agreements: ISPs are legally bound by their license to block sites identified by the Licensor (Government), often under strict confidentiality.

Methods of Implementation:

ISPs typically use three main layers to enforce blocks:

1. DNS Poisoning: The most common and cheapest method. When a user requests a blocked site, the ISP’s DNS server returns a false IP address or a Not Found message.
2. HTTP/URL Filtering: The ISP examines the web address (URL) and blocks the request if it matches a restricted list.
3. Deep Packet Inspection (DPI): A more advanced and expensive method where the ISP analyzes the actual content of the data packets to block specific traffic.

• The turtles, native to the Ganga river system and protected under Schedule I of the Wildlife Protection Act, were being illegally transported.

About Indian Softshell Turtles:

What It Is?

• The Indian Softshell Turtle (Nilssonia gangetica), also known as the Gangetic Softshell Turtle, is a large freshwater reptile. Unlike most turtles that have a hard, bony scute, these belong to the family Trionychidae, characterized by a leathery shell that lacks a traditional keratinized cover.

IUCN Status and Legal Protection:

• IUCN Red List: Endangered.
• Wildlife Protection Act (1972): Schedule I (India’s highest level of legal protection, equivalent to that of the Tiger).
• CITES: Appendix I.

Habitat and Distribution:

• Primary Range: Found predominantly in the Ganges, Indus, and Mahanadi river systems.
• Environment: They prefer deep, turbid rivers, streams, large canals, lakes, and ponds with mud or sand bottoms where they can easily bury themselves.
• Geographic Spread: Distributed across India, Pakistan, Bangladesh, and Nepal.

Key Characteristics:

• Soft Shell: It has a flat, oval, and leathery carapace (upper shell) that is olive-green or dull green in color.
• Distinct Head: The head is large with a distinctive snout-like proboscis (pointed nose) that allows it to breathe while remaining submerged.
• Size: They are massive, with the carapace length reaching up to 94 cm.
• The 20-Claw Myth: Poachers specifically target individuals with 20 claws (five on each limb), as they are falsely believed to bring good luck or have higher medicinal value in the black market.
• Diet: They are omnivorous scavengers, feeding on fish, mollusks, frogs, and occasionally rotting vegetation or carcasses.

Significance:

• As scavengers, they play a vital role in the river ecosystem by consuming organic waste and dead matter, helping to keep the Ganges and other rivers clean.
• Their presence indicates the health of the freshwater riverine systems.
