A fisheries and aquatic ecology research team from zoology department of Rajiv Gandhi University (RGU) discovered 5 species of fish from various districts of Arunachal Pradesh. The team was led by RGU Professor DN Das. Details of discovery have been published in various journals of international repute.
Majority of water bodies in remote areas of Arunachal Pradesh are still not easily accessible to researchers due to a difficult terrain which includes rain forests, steep hills besides communication problems. Researchers are however optimistic that meticulous exploration may result in more discoveries of new fish species from state in future.
Newly-Discovered Fish Species
- Mystus prabini– found in Sinkin and Dibang rivers in Lower Dibang Valley district
- Exostoma kottelati– found in Ranga river in Lower Subansiri district
- Creteuchiloglanis tawangensis– found in Tawangchu river in Tawang district
- Garra ranganensis– found in Ranga river
- Physoschistura harkishorei– found in Dibang and Lohit rivers in Lower Dibang Valley district
According to recently released report by Greenpeace India, India is the largest emitter of sulphur dioxide (SO2) in the world. The findings of report were based on data obtained from NASA’s Ozone Monitoring Instrument (OMI) satellite.
Findings of Report
Indian Scenario: It is largest emitter of SO2 in the world, with more than 15% of all anthropogenic SO2 hotspots detected by NASA OMI satellite. Most all of these anthropogenic emissions in India are because of coal-burning. This is because majority of coal-based power plants in India lack flue-gas desulphurisation (FGD) technology to reduce air pollution. Singrauli, Neyveli, Jharsuguda, Talcher, Korba, Chennai, Kutch, Ramagundam, Chandrapur and Koradi thermal power plants/clusters are major emission hotspots in India
Government Measures: Union Environment Ministry for the first time had SO2 emission limits for coal-fired power plants in December 2015 to combat pollution levels. But the deadline for installation of flue-gas desulphurisation (FGD) in power plants was extended from 2017 to 2022.
Global scenario: Largest SO2 emission hotspots have been found in Russia, South Africa, Iran, Saudi Arabia, India, Mexico, United Arab Emirates, Turkey and Serbia. Of world’s major emitters, China and United States (US) have been able to reduce emissions rapidly by switching to clean energy sources and enforcement for SO2 control. Emissions of air pollutants from power plants and other industries continue to increase in India, Iran and Saudi Arabia. In Russia, Mexico, South Africa and Turkey, emissions are currently not increasing — however, there is not lot of progress in tackling them either.
