Context: The Miyawaki method of afforestation is to come up on the government office premises, residential complexes, school premises, and puramboke land in Kerala.
What is Miyawaki method?
The Miyawaki method, developed by a Japanese botanist after whom it is named, involves planting saplings in small areas, causing them to “fight” for resources and grow nearly 10 times quicker.
It originated in Japan, and is now increasingly adopted in other parts of the world, including our Chennai. It has revolutionised the concept of urban afforestation by turning backyards into mini-forests.
The process explained:
- A pit has to be dug, and its dimensions depend on the available space. Before digging the pit, the list of tree species should be chosen judiciously. As there is very little space to work around with, trees with varying heights should be chosen.
- Fill it with one layer of compost, followed by a layer of natural waste such as bagasse and coconut shells and then top it with a layer of red soil.
- Plant the saplings following interval and tree height specifications.
- The whole process can be completed in two to three weeks. The saplings have to be maintained regularly for a year.
The exercise will cost approximately ₹ 20,000 for a 600 sq. ft mini forest.
