About Matcha Tea
- Matcha is a premium powdered green tea produced from specially cultivated Camellia sinensis leaves grown under shade before harvest.
- Production: Traditionally produced in Japan, it is also manufactured in China and Vietnam, with global demand currently exceeding supply.
- China is the largest producer of matcha accounting for approximately 70% of global production.
- Key Features
- Shade-Grown Cultivation: Tea plants are shaded for 3–4 weeks, reducing sunlight exposure by about 90% to enhance chlorophyll, amino acids and flavour.
- Whole-Leaf Consumption: Unlike conventional green tea, finely powdered leaves are whisked into water and consumed entirely, providing higher nutritional value.
- Nutrient-Rich Beverage: Contains high levels of antioxidants (catechins), L-theanine, chlorophyll and natural caffeine.
- Production Process
- Shade-grown leaves are carefully harvested, steamed, dried and de-stemmed to produce tencha.
- Tencha leaves are finely stone-ground into a vibrant green powder using specialised grinding equipment.
- Authentic production requires precise cultivation, processing and storage to preserve colour, aroma and nutritional quality.
- India–Japan Cooperation: India’s first commercial Matcha was developed through a decade-long collaboration with Japanese tea experts, showcasing successful technology and knowledge transfer.
Sub-Orbital Launch Vehicle for Experiments (SOLVE)
Context: ISRO successfully conducted the first ground test of the SOLVE solid motor, a critical test platform for validating the Gaganyaan Crew Module’s parachute-based deceleration system.
About Sub-Orbital Launch Vehicle for Experiments (SOLVE)
- SOLVE (Sub-Orbital Launch Vehicle for Experiments) is a solid motor-based test vehicle developed by Indian Space Research Organisation to validate critical technologies for the Gaganyaan mission.
- It enables integrated parachute and deceleration tests of the Crew Module under simulated mission conditions.
- Key Features
-
- Sub-orbital Test Platform: Carries the Crew Module to an altitude of 10–17 km before separation for recovery tests.
- Parachute Validation: Tests a sequence of 10 parachutes to ensure safe atmospheric deceleration and sea splashdown.
- Modified PSLV Technology: Uses a modified PSLV strap-on motor with slow-burn propellant and secondary injection thrust vector control.
- Key Preparatory Tests under Gaganyaan
-
- Pad Abort Test (PAT): Validates emergency crew escape during launch.
- Test Vehicle (TV) Missions: Demonstrate abort capability under different flight conditions.
- Integrated Air Drop Test (IADT): Validates parachute and deceleration systems.
- SOLVE: Conducts integrated parachute and Crew Module recovery tests.
- Water Survival Test Facility (WSTF): Simulates post-splashdown recovery with Indian Navy support.
Asiatic Lion
Context: The latest Asiatic lion census recorded 891 lions, reviving calls to establish a second free-ranging population outside the Gir landscape for long-term conservation.
Key Trend in Asiatic Lion Population
- Gujarat recorded 891 Asiatic lions in 2025, a 32.2% increase from 674 lions in 2020.
- About 44.22% of the population now occurs outside protected forests, indicating expansion into human-dominated landscapes.
- The Gir National Park–Gir Wildlife Sanctuary–Pania Wildlife Sanctuary complex continues to support the core breeding population.
- Barda Wildlife Sanctuary has emerged as a new lion habitat, though it remains within Gujarat.
About Asiatic Lion
- The Asiatic lion (Panthera leo persica) is the only wild lion subspecies found in Asia and is endemic to India.
- Habitat: It inhabits dry deciduous forests, scrublands, savannas and open grasslands with adequate prey and water availability.
- Distribution: The species survives exclusively in the Gir landscape of Gujarat, comprising protected forests and surrounding multiple-use landscapes.
- Conservation Status
- IUCN Red List: Endangered.
- Wild Life (Protection) Act, 1972: Schedule I.
- CITES: Appendix I.
- Key Concerns
- Single Population Risk: Concentration in one landscape increases vulnerability to epidemics, forest fires and natural disasters.
- Disease Threat: The 2018 Canine Distemper Virus (CDV) outbreak highlighted the risk of mass mortality.
- Low Genetic Diversity: Limited genetic variation increases susceptibility to diseases and reduces long-term adaptability.
- Human–Lion Interface: Increasing dispersal outside protected areas raises risks of conflict, road accidents and electrocution.
- Conservation Initiatives
- Project Lion (2020): Focuses on habitat improvement, disease surveillance, corridor development and population management.
- Supreme Court Judgment (2013): Directed translocation of Asiatic lions to Kuno National Park to establish a second free-ranging population.
