Why in news: IIT Madras and the Finnish Meteorological Institute (FMI) signed an MoU to establish VAYYU, a virtual research center to study aerosol influences on regional climate.
The VAYYU facility will use advanced simulations to analyze Himalayan snow and glacier melting, urban air quality in Indian metros, and regional hydro-climate. The project is a collaborative effort between IIT Madras and the Finnish Meteorological Institute (FMI).

Why in news: A group of 22 scientists and ecologists urged Tamil Nadu CM M.K. Stalin to withdraw the Mamallan Reservoir project to protect the Kovalam-Nemmeli backwater system.
The proposed project involves constructing a reservoir in the Kovalam-Nemmeli backwater system. Scientists argue the project would restrict tidal flow, damaging seagrass patches, mudflats, and brackish habitats.

PlaceKovalam-Nemmeli backwater system: A wetland ecosystem in Tamil Nadu.
EnvironmentSeagrass patches and mudflats: Identified as essential habitats for fish and shrimp in the backwater system.
Fact22 scientists (ecologists, hydrologists, ornithologists, and marine biologists) submitted the protest.
Mains angle
Q. Discuss the ecological implications of large-scale reservoir construction in coastal backwater systems and the importance of lagoonal wetland conservation.
Hydrological risk: Increased flooding and cyclone vulnerability due to restricted tidal flow
Biodiversity loss: Degradation of brackish habitats and seagrass patches essential for marine fauna
Conservation trade-off: Balancing infrastructure development with the preservation of lagoonal wetland ecosystems
Why in news: MARC and Social Forestry Divisions conducted a nest monitoring survey in Kannur and Kasaragod, identifying 17 active White-bellied Sea Eagle nests.
The survey conducted by MARC and Social Forestry Divisions found 17 active nesting sites, an increase from 13 sites recorded last year. The eagles were found nesting in temple compounds and populated areas, preferring large mature trees like Ficus religiosa and Mangifera indica.

FactNest count: 17 active nesting sites identified in the current survey.
Q. Discuss the challenges of conserving flagship avian species in anthropogenic landscapes and the importance of community-led conservation in temple and populated areas.
Habitat fragmentation: Encroachment on coastal ecosystems reducing historical nesting sites
Human-wildlife coexistence: Managing nesting sites within temple compounds and populated zones
Biodiversity monitoring: Limitations of periodic surveys in tracking long-term population trends
