Munroe Thuruthu: The sinking island of Kerala
|
A recent study revealed anthropogenic interventions as the main reason for the plight of Munroe Thuruthuresidents, Kerala’s first set of climate refugees.
- Munroe Thuruthu is slowly going under water
- Munroe Island is located 27 km away from the heart of Kollam.
- It is a string of eight islets at the confluence of the Ashtamudi Lake and the Kallada river.
- The island’s decline began with the construction of the Thenmala dam.
- Located 70 km away and constructed in the 1960s under the Kallada Irrigation Project, the dam blocked the flow of fresh water as a result of sediments from the Kallada river — the main determinant of the land’s fertility.
- Today the whole area has turned saline.

- Usually, flying schools use this fuel for piston-engine aircraft.
- The gas is certified by the Directorate General of Civil Aviation (DGCA) and will benefit around 35 flying schools in the country.
- Unmanned Aerial Vehicles (UAVs) are increasingly being used in modern warfare, including in Russia-Ukraine, so the development marks an important milestone for India from the perspective of defense preparedness.
