In the bustling city of Tiruchirappalli, Tamil Nadu, a green revolution is taking root through the innovative Miyawaki method. Grow Billion Trees is spearheading the transformation of underutilized urban spaces into dense, fast-growing forests of indigenous species. In just 20–30 years—compared to centuries for traditional afforestation—these mini-forests mature, improving air quality, reducing heat, enriching biodiversity, and creating vibrant, community-loved green havens filled with birds, insects, and peaceful respites for residents.
