Bombay Municipal Corporation(BMC) has been using the Miyawaki method to create tiny urban forests in the Metropolitan areas of Mumbai.
What is the Miyawaki Method?
- Miyawaki is an afforestation method based on the work of Japanese botanist Akira Miyawaki in the 1980s.
Process of Miyawaki Method:
- Initially, native trees of the region are identified and divided into four layers — shrub, sub-tree, tree, and canopy.
- After that, The quality of soil is analysed and biomass is mixed with it. Biomass mixing help to enhance the perforation capacity, water retention capacity, and nutrients.
- A mound is built with the soil and the seeds are planted at a very high density. Furthermore, the ground is covered with a thick layer of mulch.
- Multi-layered saplings are planted close to each other. This blocks sunlight from reaching the ground and prevents weeds from growing. It also keeps the soil moist.
- The close cropping also ensures that the plants receive sunlight only from the top. It enables them to grow upwards rather than sideways.
Benefits of Miyawaki Method:
- Faster Process and Dense Forest: This method creates mini forests. They grow 10 times faster and become 30 times denser and 100 times more biodiverse than those planted through conventional methods.
- Faster Regeneration of Land: Miyawaki forests are designed to regenerate land in far less time. It takes over 70 years for a forest to recover on its own.
- Self Sustainable: The saplings become self-sustainable after the first three years.
- Environmental Benefits: These mini forests help lower temperatures in concrete heat islands, reduce air and noise pollution, attract local birds and insects, and create carbon sinks.
