MIYAWAKI METHOD

WHY IN NEWS?

PIB: In a bid to boost forest cover in the coal belt region of Chhattisgarh, Coal India Ltd subsidiary, South Eastern Coalfileds Ltd (SECL) will undertake plantation using the Miyawaki method for the first time in its operational areas. 

ABOUT

The Miyawaki method of plantation was pioneered in the 70s by Japanese botanist and expert in plant ecology Mr. Akira Miyawaki.

It has revolutionised the concept of urban afforestation by turning backyards into mini-forests.

Miyawaki method helps to create a forest in just 20 to 30 years, while through conventional methods it takes anywhere between 200 to 300 years.

PROCESS

• The native trees of the region are identified and divided into four layers — shrub, sub-tree, tree, and canopy.
• The quality of soil is analysed and biomass which would help enhance the perforation capacity, water retention capacity, and nutrients in it, is mixed with it.
• A mound is built with the soil and the seeds are planted at a very high density — three to five sapling per square meter which not only saves space, but block sunlight reaching the ground, thereby preventing the growth of weed.
• The saplings become maintenance-free (self sustainable) after the first three years
