ISRO launches 2250 kg NVS-03 satellite to restore NavIC services in 18 minutes

Why in news: ISRO successfully launched the 2250 kg NVS-03 satellite using the GSLV-F18 to restore NavIC services after previous satellite failures.

The NVS-03 satellite weighs 2250 kg and was launched from the Satish Dhawan Space Centre using the GSLV-F18 vehicle. It carries an indigenous atomic clock and provides L1 signals alongside existing L5/S signals for a 12-year mission life.

Prelims pointers (4)
  • S&TGSLV-F18: The launch vehicle used to inject the NVS-03 satellite into a geosynchronous transfer orbit.
  • FactNVS-03: A 2250 kg satellite designed to provide continuity for the Navigation with Indian Constellation (NavIC).
  • S&TNavIC Coverage: Provides PNT services over the Indian landmass and a region extending 1,500 km beyond the Indian geopolitical boundary.
  • S&TNVS-03 Signals: Includes L1 signals in addition to existing L5 and S signals.
Mains angle

Q. Discuss the significance of the Navigation with Indian Constellation (NavIC) in ensuring India's strategic autonomy and enhancing domestic infrastructure.

  • Strategic Autonomy: Reducing dependence on foreign GNSS like GPS or GLONASS for critical infrastructure.
  • Technological Sovereignty: Development of indigenous atomic clocks and signal processing for secure PNT services.
  • Economic Utility: Enhancing precision for disaster management, maritime safety, and agricultural mapping.

Forest department and PCK to survey Athirappilly land over elephant corridor obstruction

Why in news: The Forest department and Plantation Corporation, Kerala (PCK) are conducting a joint survey of a two-hectare leased forest land at Athirappilly to address elephant corridor obstructions and human-wildlife conflicts.

The survey concerns a two-hectare leased forest land at Athirappilly where the lease expired a decade ago. The investigation targets alleged elephant corridor obstructions, tiger-related human-wildlife conflicts, and unauthorized private pineapple farming.

Prelims pointers (4)
  • PlaceAthirappilly: Location of the forest land survey in Kerala
  • FactTwo-hectare: Size of the leased forest land under survey
  • BodyPlantation Corporation, Kerala (PCK): Body involved in the joint survey
  • EnvironmentElephant corridor: Ecological pathway being obstructed by land use
Mains angle

Q. Discuss the challenges in balancing commercial land use with the preservation of wildlife corridors in ecologically sensitive zones like Kerala.

  • Ecological fragmentation: Obstruction of elephant corridors leading to increased human-wildlife conflict
  • Regulatory oversight: Enforcement of lease conditions against unauthorized private farming in forest zones
  • Judicial intervention: Kerala High Court's stance against sub-leasing of forest land

Naidu announces ₹3,000 crore to modernise Godavari irrigation drains against crop inundation

Why in news: Andhra Pradesh CM N. Chandrababu Naidu announced a ₹3,000 crore modernization plan for Godavari irrigation drains to mitigate crop inundation following Cyclone Arnab.

The Andhra Pradesh government pledged ₹5 lakh ex gratia for deaths, ₹25,000 per hectare for damaged crops, and ₹18,000 for aquaculture ponds. During the event, 4.68 TMC of rainwater was diverted to reservoirs, and groundwater improved by approximately 44 TMC.

Prelims pointers (5)
  • Fact₹3,000 crore allocated for modernising irrigation drains in the Godavari region
  • Fact₹25,000 per hectare provided as compensation for damaged crops
  • Fact₹18,000 compensation provided for aquaculture ponds
  • Fact4.68 TMC of rainwater diverted to reservoirs during Cyclone Arnab
  • FactGroundwater improved by approximately 44 TMC
Mains angle

Q. Discuss the importance of modernizing irrigation infrastructure in coastal states to mitigate the impacts of extreme weather events on agricultural productivity.

  • Infrastructure gap: Inadequate drainage systems leading to prolonged crop inundation in deltaic regions
  • Climate adaptation: Balancing surface water diversion with groundwater recharge during extreme rainfall events

The India Meteorological Department warned a low-pressure area may become a depression

Why in news: The India Meteorological Department (IMD) issued a warning regarding a low-pressure area potentially intensifying into a depression over the southeast Bay of Bengal.

The IMD warned of a potential depression over the southeast Bay of Bengal as of October 31. Reports indicated heavy rains and temperatures reaching 37°C in Anantapur, while teams were deployed to assess Cyclone Arnab damage and drought in 283 mandals.

Prelims pointers (1)
  • Fact283 mandals were identified as severely affected by drought and Cyclone Arnab damage.
Mains angle

Q. Discuss the challenges faced by coastal states in managing the dual impact of cyclonic storms and prolonged droughts in the face of climate change.

  • Infrastructure gap: Inadequate drainage and coastal embankments leading to prolonged waterlogging in rural mandals
  • Data-driven response: Need for real-time hydrological modeling to manage simultaneous drought and flood risks
