Arctic Acidification

  • Researchers have recently highlighted the changing chemistry of the western region of Arctic Ocean.
  • Scientists have predicted that by 2050, Arctic sea ice in this region will no longer survive the increasingly warm summers.
  • As a result, the ocean’s chemistry will grow more acidic.

pH is a measure of the level of acid or alkali in a water and Seawater is normally alkaline, with a pH value of around 8.1.

  • Acidification creates life-threatening problems for the diverse population of sea creatures, plants and other living things that depend on a healthy ocean.

Ocean Acidification is a process of dissolving CO2 in seawater which forms carbonic acid by decreasing the ocean’s pH.

  • The researchers have also identified a strong correlation between the accelerated rate of melting ice and the rate of ocean acidification (rapid pH decrease).
  • Increasing rate of melting changes the surface water in three primary ways.
  1. The water under the sea ice, which had a deficit of carbon dioxide, now is exposed to the atmospheric carbon dioxide and can take it up freely.
  2. The seawater mixed with meltwater is light and can’t mix easily into deeper waters, which means the carbon dioxide is concentrated at the surface.
  3. The meltwater dilutes the carbonate ion concentration in the seawater, weakening its ability to neutralise the carbon dioxide into bicarbonate and rapidly decreasing ocean pH.

Community reserves

Increasing community reserves in North East India poses a serious question about the backdoor entry of the forest department.

  • Unlike other regions of India, administrative control of forests in the North East is predominantly by communities, with much of the forests listed as ‘unclassified’.
  • But North East India has seen a rapid increase of community reserves in the last 11 years.
  • A community reserve is usually formed by the local village council and the forest department signing a memorandum of understanding (MoU).
  • Community reserves fall under the protected areas, along with marine protected areas, national parks, wildlife sanctuaries and conservation reserves, according to the Wild Life (Protection) Act (WLPA), 1972.
  • Once a forest land has been declared a community reserve, its governance comes under forest department instead of being governed by the local village councils.
  • After a forest has been made into a community reserve, people cannot hunt there, nor can they use it for agricultural practices, leave alone jhum cultivation.
  • But the village council members who agree to sign the MoU are mostly illiterate and do not know what they are getting into and changes the lives of local residents.
