{GS2 – IR} India Ends Ayni Air Base Presence

• Context (TOI): India ended its activities at Ayni Air Base in 2022 following the expiration of the bilateral defence agreement with Tajikistan.

About Ayni Air Base

• The Ayni Air Base, also known as Gissar Air Base, is a Soviet-era military facility near Dushanbe, the capital of Tajikistan.
• Redevelopment Effort: India redeveloped the air base in 2002 with an estimated $100 million to upgrade runways, air defence systems, and radar infrastructure.
• Strategic Objective: The redevelopment aimed to support the anti-Taliban Northern Alliance in Afghanistan and expand India’s regional presence in Central Asia.
• Operational Exit: India withdrew all personnel and equipment in 2022 after Tajikistan declined to renew the defence agreement.

Strategic Significance of Ayni Air Base

• Regional Presence: Ayni gave India a strategic foothold in Central Asia and acted as a key pillar of its “Connect Central Asia” policy.
• Intelligence Role: Its proximity to Afghanistan, Pakistan, and China allowed India to monitor regional military and insurgent activities.
• Independent Connectivity: The base provided a direct and secure air access to Afghanistan and Central Asia, bypassing Pakistan’s restricted airspace.
• Operational Support: Ayni operated as a logistics and humanitarian hub and played a key part in Operation Devi Shakti (India’s 2021 mission to evacuate citizens from Afghanistan).

{GS3 – IE} India’s $30 Trillion Economy Projection **

• Context (BS | IE): According to the Commerce and Industry Minister, India is projected to become a $30 trillion economy within the next 20-25 years.

• India’s GDP for FY 2024 stood at $3.9 trillion, while the U.S. GDP was $29.2 trillion, roughly eight times.

Understanding the Projection

• The size of an economy is measured by its Nominal Gross Domestic Product (GDP), the total market value of goods and services produced in a year, expressed in U.S. dollars for global comparison.
• Two key factors determine this figure:
  • Nominal GDP growth in rupee terms (domestic economic expansion).
  • Rupee-dollar exchange rate, which converts domestic value into global terms.

Historical Growth Patterns of India

• Over the past 25 years (2000-2024), India’s nominal GDP grew at a CAGR of 11.9%, and the rupee depreciated at a CAGR of 2.7%.
  • Based on this trend, India could reach $30 trillion by 2048 within 25 years, consistent with the ministry’s forecast.
• However, in the past 11 years (2014-2025), Nominal GDP growth slowed to 10.3%, and rupee depreciation quickened to 3.1%.
  • Under these conditions, India may reach $30 trillion only by 2055, nearly a decade later.

Current Affairs

Factors Influencing the Projection

• Exchange Rate Volatility: A stronger rupee accelerates progress toward the $30 trillion mark while sustained depreciation delays it.
• Growth Moderation: As economies mature, growth rates tend to moderate. India, however, remains at a stage where higher growth is still feasible and necessary.
• Structural Reforms: It will be crucial to continue focusing on manufacturing, infrastructure, digital transformation, and ease of doing business.
• Inflation and Fiscal Health: Maintaining macroeconomic stability and low inflation is essential to sustain long-term growth.
  • As the analysis highlights, each decade’s performance matters; even minor shifts in growth trajectory can lead to large divergences over time.

{GS3 – S&T} Enshittification

• Context (TH): The digital spaces that once symbolised freedom, creativity, and connectivity are increasingly seen as exploitative ecosystems prioritising profit over user experience.

Symptoms of Enshittification

• Ad Saturation: Excessive unskippable ads and paywalls replacing once-free experiences. E.g. YouTube Premium and Netflix ad tiers (2024).
• Algorithmic Manipulation: Prioritising viral or paid content over authentic connections. E.g. Instagram’s algorithm now favours reels over user posts.
• Self-Preferencing: Tech giants promote their own content or products over competitors. E.g., Amazon’s sponsored results dominate search listings (FTC case, 2024).
• Data Exploitation: User data repurposed for micro-targeted advertising without transparency. E.g. Cambridge Analytica scandal (2018) exposed large-scale political profiling.
• Loss of Authenticity: Paid verifications and bots distort discourse and trust. E.g., X (Twitter) verification is now purchasable by anyone, including fake accounts.

{Prelims – Species} Water Lettuce (Pistia stratiotes)

• Context (RE): Invasive aquatic species Water Lettuce (Pistia stratiotes) has overrun Lake Suchitlán in El Salvador, threatening local fisheries and livelihoods.

About Water Lettuce (Pistia stratiotes)

• Water lettuce, also called water or Nile cabbage, is a free-floating freshwater plant with leaves that resemble a head of lettuce.
  • It is a popular ornamental plant but is also considered an invasive weed.
• Habitat Preference: It thrives in still or slow-moving freshwater environments (i.e., ponds, lakes, and reservoirs), mainly in tropical and subtropical regions.
• Physical Traits: The plant has soft green leaves with fine white hairs that trap air bubbles, and unbranched roots with a hair-like appearance.
• Invasive Nature: Its fast growth and mat formation block sunlight, deplete oxygen, and disrupt local aquatic biodiversity.
• Ecological Role: Despite being invasive, it provides temporary refuge for fish and helps suppress algal blooms by absorbing excess nutrients.
• Human Use: It is unsafe for human consumption due to high concentrations of calcium oxalate crystals that irritate mucous membranes.
  • Phytoremediation: Its hyperaccumulation ability makes it useful for phytoremediation, wastewater treatment, and oil-spill cleanup.
• Conservation Status: IUCN: Least Concerned
