Yelagiri hut

Over 200 Malaiyali tribespeople once inhabited traditional clay huts atop Yelagiri hill in northern Tamil Nadu, now replaced by modern homes except for one ancient hut, symbolizing their transition from foraging to modern living.

About Yelagiri hut:

  • The hut is formed of red clay on a teak wood structure.
  • Made of dry bamboo leaves, the thatched roof is waxed with cow dung to prevent it from leaking during the monsoon season. 
  • Weatherproofed: A unique feature of the munn veedu(mud house) or andara kotai (storage facility) is that it stands on a stilt-like structure also made of teak wood.
    • This holds the house two feet above the ground to keep rodents at bay and to prevent the house from flooding during torrential rains.

About Malaiyali tribe:

  • The Malaiyali tribe – malai meaning “hill” and yali meaning “people” – is strewn across Tamil Nadu’s hilly regions.
  • The tribespeople were foragers who settled in the upper Nillavur region of Yelagiri and began cultivating its tabletop peak for food.
  • Initially living in makeshift huts, they found a permanent solution in the red loam clay abundant in the hills and constructed simple one-room structures that measured 16 by 22 feet.

  • The two main issues addressed in a general review of quotas are the
    • size of an overall quota increase
    • distribution of the increase among the members

Economy (GS-III)


China reported “deflation” in July. 

What is Deflation?

  • Deflation is when the general price levels in a country are falling—as opposed to inflation when prices rise.
  • Deflation can be caused by an increase in productivity, a decrease in overall demand, or a decrease in the volume of credit in the economy.
  • Most of the time, deflation is unambiguously a positive trend for the economy, but it can also under certain conditions occur along with a contraction in the economy.
  • In an economy dominated by debt-fuelled asset price bubbles, deflation can lead to a temporary financial crisis and a period of liquidation of speculative investment known as debt deflation.


China’s Sponge cities initiative

China has been hit by devastating floods recently, inundating cities and causing infrastructural damage, as well as raising questions about the effectiveness of its 2015 “sponge city” initiative aimed at reducing urban flood risks.

About Sponge cities initiative:

  • The “sponge city” initiative was designed to make greater use of lower-impact “nature-based solutions” to better distribute water and improve drainage and storage.
  • Those solutions included the use of permeable asphalt, the construction of new canals and ponds and also the restoration of wetlands, which would not only ease waterlogging, but also improve the urban environment.
  • However, the sponge city infrastructure can only handle no more than 200 millimetres (7.9 inches) of rain per day.
