  • It typically has explosive eruptions and pyroclastic flows –– defined as a high-density mix of hot lava blocks, pumice, ash and volcanic gas.
  • It has erupted more than 50 times and is considered among the most dangerous volcanoes in the world due to its proximity to Naples and surrounding towns.
  • Its last serious eruption, lasting two weeks, was in 1944 during World War II, which left 26 Italian civilians dead and around 12,000 displaced.

  • The Asan Conservation Reserve in Dehradun, the first wetland from Uttarakhand to be recognised by Ramsar convention, was added to the list in October this year.

Back2Basics: Wetlands

  • A wetland is a distinct ecosystem that is flooded by water, either permanently or seasonally, where oxygen-free processes prevail.
  • The primary factor that distinguishes wetlands from other landforms or water bodies is the characteristic vegetation of aquatic plants, adapted to the unique hydric soil.
  • Wetlands provide a wide range of important resources and ecosystem services such as food, water, fibre, groundwater recharge, water purification, flood moderation, erosion control and climate regulation.

What is the Ramsar Convention?

  • The Ramsar Convention on Wetlands of International Importance Especially as Waterfowl Habitat is a treaty for the conservation and sustainable use of such sites.
  • The convention, signed in 1971 in the Iranian city of Ramsar, is one of the oldest inter-governmental accords for preserving the ecological character of wetlands.
  • Also known as the Convention on Wetlands, it aims to develop a global network of wetlands for the conservation of biological diversity and for sustaining human life.
  • Over 170 countries are party to the Ramsar Convention and over 2,000 designated sites covering over 20 crore hectares have been recognised under it.

  • When the Soviet Union began to collapse in the late 1980s, Armenia’s regional parliament voted for the region’s transfer to Armenia; the Soviet authorities turned down the demand.
  • Years of clashes followed between Azerbaijan forces and Armenian separatists.
  • The violence lasted into the 1990s, leaving tens and thousands dead and displacing hundreds of thousands.
  • In 1994, Russia brokered a ceasefire, by which time ethnic Armenians had taken control of the region.
