Explanation

The "Miyawaki method" is an innovative and highly effective technique for afforestation, developed by Japanese botanist Akira Miyawaki. This method involves planting diverse native species in a very dense and specific pattern. By creating a multi-layered forest structure (shrubs, sub-trees, trees, canopy trees) and enriching the soil, the method accelerates forest growth by about 10 times and makes the resulting mini-forests self-sustaining and maintenance-free after a few years. It is particularly well-known for its application in creating dense, biodiverse mini-forests in small urban plots, neglected spaces, or industrial sites, contributing to urban greening and ecological restoration.
