Bao Dhaan (Geography)

Recently, the first consignment of ‘Bao Dhaan or Red Rice‘ was sent to the USA from Assam.

Key Points

  • The red rice is iron-rich and is grown in the Brahmaputra valley of Assam, without the use of any chemical fertilizer. 
    • The rice variety is referred to as ‘Bao-dhaan‘, and it is red due to the presence of anthocyanin
    • It is an integral part of Assamese food.
    • It has a nutty flavor.

  • Compared to brown and white rice, it has the highest nutritional value.
  • Varieties: Thai Red Cargo rice, Bhutanese red rice, Camargue red rice, and Kerala Matta rice.
  • Geographical Conditions:
    • Climate: Warm and humid
    • Temperature: 20°C to 35°C
    • Rainfall: 100 cm 
    • Soil: Fertile soil. Delta and valley soils are the most suitable.

Jalyukta Shivar Yojana Project (Government Schemes)

Recently, the Mounda tehsil in Maharashtra was turned into a water-surplus tehsil under Jalyukta Shivar Yojana Project.

Jalyukta Shivar Yojana Project

  • Launched in: 2014
  • Launched by: Government of Maharashtra.
  • Aim: To make Maharashtra a drought-free state by 2019
    • To make 5000 villages free of water scarcity every year in regions including Marathwada and adjoining areas of Madhya Maharashtra and large parts of Vidarbha.
  • The recent state government has ended this scheme in 2020. 

UV Disinfection Technology (S&T)

Recently, CSIR- CSIO has transferred UV Disinfection technology to combat SARS-CoV-2 to some indigenous manufacturers.

  • There has been increasing evidence for the airborne route of transmission of SARS-CoV-2 via aerosols.
  • Airborne transmission is a major risk in indoor settings.

UV Disinfection Technology

  • The UV-C air duct disinfection system can be used in Air Handling Units (AHUs) like auditoriums, large conference rooms, classrooms, malls, etc. for disinfection
  • Purpose: To deactivate the SARS COV-2 virus contained in an aerosol with necessary ventilation measures, necessary safety and user guidelines, and tested Bio-safety standards, etc.
    • An aerosol is a suspension of small liquid droplets or solid particles in the air. 
    • The aerosol material exists in the liquid or solid state and is carried by air into the respiratory tract.
  • Utility: 
    • UV-C deactivates over 99 % of viruses, bacteria, fungus, and other bioaerosols, etc., and ameliorating fungal infections.
    • The UV-C is energy efficient system, improves airflow through coils, enhances indoor air quality, requires less maintenance, easy to retrofit with any existing system having AHU ducts, and has a low initial setup cost.

Ultraviolet (UV) Radiation

  • It is a form of non-ionizing radiation that is emitted by the sun and artificial sources, such as tanning beds.
  • UV radiation is classified into three primary types: ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC)
    • These groups are based on the measure of their wavelength, which is measured in nanometers.
    • UVA: 
      • Wavelength: 315- 399 nm
      • Absorption Level: Not absorbed by the ozone layer.
    • UVB: 
      • Wavelength: 280-314 nm
      • Absorption Level: Mostly absorbed by the ozone layer, but some do reach the Earth’s surface.

  • Location: Inside Virunga National Park, Congo.
    • Location: Albertine Rift Valley of Great Rift Valley.
    • It is listed in the List of World Heritage in Danger and UNESCO World Heritage Sites.
    • Apart from Mount Nyiragongo, another active volcano Mount Nyamuragira is located here.
    • Here around 1/3 of the world’s wild mountain gorillas are present.
