■ YELLOW STONE NATIONAL PARK

#Climatechange

□ ABOUT :-

◇ American national park located in the western United States, largely in the northwest corner of Wyoming and extending into Montana and Idaho.

◇ It is the first national park in the US and is also widely held to be the first national park in the world.

◇ The park is known for its wildlife and its many geothermal features, especially Old Faithful geyser, one of its most popular.

◇ It represents many types of biomes - the subalpine forest is the most abundant. It is part of the South Central Rockies forests ecoregion.

□ IMPACT OF CLIMATE CHANGE.

◇ Since 1950, average temperatures in the Greater Yellowstone Area have risen 1.3°C and potentially, more importantly, the region has lost a quarter of annual snowfall.

◇ The loss of snow there has repercussions for a vast range of ecosystems and wildlife, as well as cities and farms downstream.

2021-09-07 08:30:08 ■ SOUTH CHINA SEA DISPUTE

#Internationalinstitutions

□ ABOUT :-

◇ It is a dispute over territory and sovereignty over ocean areas, and the Paracels and the Spratlys – two island chains claimed in whole or in part by a number of countries.

◇ China, Vietnam, the Philippines, Taiwan, Malaysia, and Brunei all have competing claims.

◇ Alongside the fully-fledged islands, there are dozens of rocky outcrops, atolls, sandbanks, and reefs, such as the Scarborough Shoal.

□ SPAT OVER CHINESE CLAIM :-

◇ China has backed its expansive claims with island-building and naval patrols.

◇ The US says it does not take sides in territorial disputes but has sent military ships and planes near disputed islands, calling them “freedom of navigation” operations to ensure access to key shipping and air routes.

◇ Both sides have accused each other of “militarizing” the South China Sea.

■ LEMRU ELEPHANT RESERVE

#Conservation

□ ABOUT :-

◇ The proposal for the reserve, in Korba district, was passed unanimously by the Assembly in 2005 and got central approval in 2007.

◇ Lemru is one of two elephant reserves planned to prevent human-animal conflict in the region, with elephants moving into Chhattisgarh from Odisha and Jharkhand.

◇ Its area was then proposed to be 450 sq km.

□ Why does the government want to reduce the size of the reserve ?

◇ The area proposed under the reserve is part of the Hasdeo Aranya forests, a very diverse biozone that is also rich in coal deposits.

◇ Of 22 coal blocks in the area, seven have already been allotted with mines running in three, and in the process of being established in the other four.

◇ Under the ‘No-Go Area’ policy from the UPA area, the entire area was considered out of bounds for mines, but in 2020, five coal blocks from the region were put on the auction list.

■ HAWAII'S KILAUEA VOLCANO

Geologists have detected a swarm of earthquakes at Hawaii’s Kilauea volcano, though it was not erupting.

□ ABOUT :-

◇ Kilauea is about 200 miles south of Honolulu, on the Big Island of Hawaii.
It is one of the world’s most active volcanoes, having erupted 34 times since 1952.

◇ In Hawaiian tradition, Kilauea is home to the volcano goddess Pele.

◇ From 1983 to 2018, it erupted almost continuously, in some cases sending streams of lava that covered farms and homes.

◇ At the end of this decades-long eruption, Kilauea spewed lava from vents in a residential neighborhood on its eastern flank and destroyed more than 700 homes.

◇ In December, Kilauea erupted at the crater, creating a lake with enough lava to fill 10 Hoover dams. That eruption ended in May.

■ SAMBHAR SALT LAKE.

#Conservation

World-famous Sambhar Salt Lake in Rajasthan is constantly shrinking with the degradation of soil and water quality and a decline in the population of migratory birds.

□ ABOUT :-

◇ The lake, situated 80 km south-west of Jaipur, is the country’s largest inland saline water body which attracts thousands of migratory birds every year.

◇ Death of more than 20,000 birds belonging to 10 species which migrate annually to the lake had made headlines in 2019.

◇ It has been designated as a Ramsar site because the wetland is a key wintering area for tens of thousands of pink flamingos and other birds that migrate from northern Asia and Siberia.

□ Threats : Illegal mining.

◇ 30% of the Sambhar Lake’s area had been lost to mining and other activities, including the illegal salt pan encroachments.

◇ It has also threatened the livelihoods of local people who have always lived in harmony with the lake.
