Topics Discussed on Daily Current Affairs 11 March 2026 for UPSC Exam

The Daily Current Affairs for 11 March 2026 covers the following key national and international issues relevant for UPSC preparation:

• West Asia Crisis and Natural Gas Supply Disruptions

• India’s First OTEC Desalination Plant in Lakshadweep

• Nirbhaya Nisha Initiative by Kerala Police

West Asia Crisis and Natural Gas Supply Disruptions

Tensions in West Asia involving Iran, Israel, and the United States have disrupted global natural gas supply chains. Iran reportedly targeted gas infrastructure connected to Qatar, which supplies a significant portion of the world’s liquefied natural gas.

India imports a major share of its natural gas from Qatar, making the situation important for energy security.

The disruption has forced India to consider alternative sources such as Norway and the United States. However, the longer shipping distance may increase transportation time and cost.

UPSC Mains Angle

• Impact of geopolitical conflicts on India’s energy security

• Diversification of energy import sources

• Role of strategic energy partnerships

India’s First OTEC Desalination Plant in Lakshadweep

India has launched its first Ocean Thermal Energy Conversion (OTEC) powered desalination plant in Kavaratti Island, Lakshadweep.

The project was developed by the National Institute of Ocean Technology (NIOT) under the Ministry of Earth Sciences.

OTEC technology generates energy using the temperature difference between warm surface seawater and cold deep-sea water. This energy is used to operate a desalination plant that converts seawater into drinking water.

The plant is expected to generate around 60–65 kW of power and produce about 1 lakh litres of drinking water per day.

Significance

• Provides sustainable drinking water supply to island regions

• Promotes renewable energy-based infrastructure

• Reduces dependence on fossil fuels

UPSC Mains Angle

• Role of renewable energy technologies in coastal regions

• Importance of desalination for water security

• Marine technology innovations in India

Nirbhaya Nisha Initiative by Kerala Police

The Nirbhaya Nisha initiative was launched by the Kerala Police to improve women’s safety during night hours.

The program aims to ensure safe movement for women between 9 PM and 5 AM in urban areas.

Key Features

• Integration with Emergency Helpline 112

• AI-based monitoring systems

• Smart safety poles with surveillance cameras and panic buttons
  
  

• Increased night patrols and hotspot monitoring
  
  

The initiative focuses on vulnerable locations such as IT parks, hospitals, bus stations, and railway stations.

UPSC Mains Angle

• Role of technology in policing

• Women’s safety and gender-sensitive governance

• Impact on female workforce participation

Exercise Dharma Guardian 2026 (India–Japan Military Exercise)

Exercise Dharma Guardian is a joint military exercise between India and Japan.

The 2026 edition was conducted in Uttarakhand, involving the Indian Army and Japan Ground Self-Defense Force.

The exercise started in 2018 and is conducted annually, alternating between India and Japan.

Objective

• Enhance interoperability between the two forces

• Improve coordination in counter-terrorism operations

• Strengthen India–Japan strategic partnership

UPSC Mains Angle

• Defence cooperation under the Indo-Pacific strategy

• India–Japan bilateral security relations

• Role of military exercises in regional stability

Exercise Lamitye 2026 (India–Seychelles Military Exercise)

Exercise Lamitye is a joint military exercise between India and Seychelles.

The 11th edition of Lamitye 2026 began on 9 March 2026 and will continue until 20 March 2026.

The exercise is hosted by the Seychelles Defence Academy and aims to strengthen defence cooperation.

Key Participation

• Indian Army (Assam Rifles troops)

• Indian Navy ship INS Trikand

• Indian Air Force C-130 aircraft

Significance

• Enhances maritime security in the Indian Ocean Region

• Strengthens India’s strategic presence in the Western Indian Ocean

• Improves joint operational capabilities
  
  

UPSC Mains Angle

• India’s maritime diplomacy

• Strategic importance of Indian Ocean islands

• Defence partnerships with small island nations

Discovery of Dark Oxygen in the Pacific Ocean

Scientists recently discovered Dark Oxygen in the deep Pacific Ocean at a depth of about 4000 meters, where sunlight cannot penetrate.

The discovery was made in the Clarion–Clipperton Zone, located between Mexico and Hawaii.

Traditionally, oxygen production is associated with photosynthesis, which requires sunlight. However, the discovery of oxygen in deep ocean regions suggests alternative chemical processes may produce oxygen.

Researchers believe polymetallic nodules on the ocean floor may create small electrical currents that split water molecules into hydrogen and oxygen.

UPSC Mains Angle

• Implications for marine ecosystem research

• Scientific importance for deep-sea exploration

• Concerns regarding deep-sea mining

War of Attrition in International Conflicts

Experts describe the ongoing Iran-related conflict as a War of Attrition.

A war of attrition is a military strategy where one side attempts to gradually weaken the enemy by exhausting its resources, manpower, and economy, rather than achieving immediate victory.

This strategy was historically used during World War I and the Iran–Iraq War.

UPSC Mains Angle

• Military strategy concepts in international relations

• Economic and humanitarian impacts of prolonged conflicts

• Strategic challenges in modern warfare

Early Heatwave Conditions in North India

The India Meteorological Department (IMD) reported early heatwave conditions in North and West India, where temperatures are 8–13°C above normal levels.

Causes

• Reduced winter rainfall due to weak Western Disturbances

• Low soil moisture levels

• Early northward movement of the sun

• Climate change effects

Impact

• Damage to Rabi crops such as wheat and barley
