Correct Answer: Option (C) — Creation of mini forests in urban areas

Concept & Option Breakdown

Standard Reference Verified

The Miyawaki method, pioneered by Japanese botanist Akira Miyawaki, is an urban afforestation technique designed to create dense, multi-layered mini-forests in small urban spaces and backyards. By planting native species close together (3 to 5 saplings per square metre across four layers: shrub, sub-tree, tree, and canopy), it enables rapid growth, making the forest self-sustaining within 2 to 3 years and mature in 20 to 30 years compared to centuries through conventional afforestation.
