Miyawaki Method - UPSC Current Affairs

The Miyawaki method is a technique for creating dense, multi-layered forests that mimic natural ecosystems in a short period of time. This method involves planting a variety of native species in a small area, resulting in a self-sustaining forest that can grow up to ten times faster and be 30 times denser than traditional methods.

The Miyawaki Method is a unique technique used for afforestation and creating dense forests with native plants. Developed by Japanese botanist Akira Miyawaki, it is used worldwide for urban afforestation by growing forests in small spaces such as backyards. This technique requires a small space of at least 20 square feet, and plants are seeded very closely to each other to save space and promote dense plant growth. The aim is to achieve plant growth ten times faster and vegetation thirty times denser than usual. The forest must be maintained for at least three years.


The Miyawaki method has four main steps. The first step involves examining the soil texture and measuring the existing biomass of the soil. The second step involves selecting native plant species and identifying their genus, height and influence on nature. The third step is to prepare the ground and equip the forest area before planting. The final step is to start the plantation process and take care of the forest for the next three years.


This method helps create self-sustaining vegetation within two to three years, whereas traditional afforestation procedures take nearly 100 years. The Miyawaki Method is based on natural reforestation principles, using trees native to the area and replicating natural forest regeneration processes. It has significant benefits over more traditional forestry methods when used in smaller afforestation projects and is particularly effective in the urban environment. Trees planted using this method grow much faster, jump-starting the forest creation process and capturing more carbon. Higher biodiversity has been recorded in Miyawaki forests than in neighbouring woodland, making it an ideal method for creating diverse forest ecosystems quickly.


In conclusion, the Miyawaki Method is one of the most effective tree planting methods for creating forest cover quickly on degraded land that has been used for other purposes such as agriculture or construction. Within the context of the current climate change emergency and warnings about the global loss of biodiversity, being able to create diverse, healthy forests quickly could prove vital to meeting international targets and tackling these issues. Although some environmentalists question this technique's efficacy, it has many benefits for nature and is an excellent way to create more green spaces in urban environments.
