Van Mahotsav Programme

Why in News?

Recently, The Chhattisgarh Forest Department organised a Van Mahotsav programme in the Manendragarh-Chirmiri-Bharatpur (MCB) district by planting saplings using the Miyawaki method.

Key Points

• Around 6,000 seedlings were planted at five distinct locations. The primary aim behind adopting the Miyawaki technique is to mitigate urban heat islands and pollution.
• Miyawaki method:
  • It was named after Japanese botanist Akira Miyawaki, this method involves planting two to four different types of indigenous trees within every square metre.
  • The methodology was developed in the 1970s, with the basic objective to densify green cover within a small parcel of land.
  • In this method, the trees become self-sustaining and they grow to their full length within three years.
    • The plants used in the Miyawaki method are mostly self-sustaining and don’t require regular maintenance like manuring and watering.
  • Significance:
    • The dense green cover of indigenous trees plays a key role in absorbing the dust particles of the area where the garden has been set up. The plants also help in regulating surface temperature.
      • Some of the common indigenous plants that are used for these forests include Anjan, Amala, Bel, Arjun and Gunj.
    • These forests encourage new biodiversity and an ecosystem which in turn increases the fertility of the soil.
