Miyawaki Technique

Why in News? 

The Prayagraj Municipal Corporation has developed dense forests at multiple locations across Prayagraj to provide pure air and promote a healthy atmosphere.  

• Using the Japanese Miyawaki technique, the corporation established several oxygen banks that have now evolved into lush green forests.  

 Key Points 

• Benefits of the Project: 
  • The initiative aids in managing industrial waste and reduces dust, dirt, and foul odours. 
  • It significantly improves the city's air quality and promotes environmental conservation. 
  • Miyawaki forests help reduce air and water pollution, prevent soil erosion, and enhance biodiversity. 
• Environmental Impact: 
  • These forests lower the temperature difference between day and night during summers. 
  • They enhance biodiversity, improve soil fertility, and create habitats for animals and birds. 
  • Large forests developed through this technique reduce temperatures by 4 to 7 degrees Celsius. 
• Diversity of Species in Miyawaki Forests: 
  • Fruit-bearing trees: Mango, Mahua, Neem, Peepal, Tamarind, Amla, and Ber. 
  • Medicinal and ornamental plants: Tulsi, Brahmi, Hibiscus, Kadamba, Bougainvillea, and Jungle Jalebi. 
  • Other species: Arjuna, Teak, Sheesham, Bamboo, Kaner (red and yellow), Tecoma, Kachnar, Mahogany, Lemon, and Drumstick (Sahjan). 

 The Miyawaki Technique 

• About: 
  • Developed by Japanese botanist Akira Miyawaki in the 1970s, this method creates dense forests in limited spaces. 
  • Known as the ‘pot plantation method,’ it involves planting native species closely together for rapid growth. 
• Key Features and Benefits: 
  • Plants grow 10 times faster, mimicking natural forests with dense plantations. 
  • Improves soil quality, biodiversity, and carbon absorption. 
  • Effective in urban areas for transforming polluted and barren lands into green ecosystems.
