Miyawaki forest is a method of afforestation developed in Japan. It involves the planting of saplings in a small area resulting in formation of dense forests in relatively short time periods. The method is specifically used in urban areas to increase green cover. Some of the advantages of the method include low space requirements and lower chances of weed growth as the dense canopy prevents sunlight from reaching the ground. The Mansa unit of Punjab state Police is developing Miyawaki forests.
