IASCODEX · Accepted Answer

Correct Option: C. Creation of mini forests in urban areas

Strategy: Identify the Miyawaki method's unique association with afforestation and urban forestry. This method is distinct from agricultural, genetic, or renewable energy contexts, with 'mini forests' in urban settings being a key indicator.

Key Info: The Miyawaki method, pioneered by Japanese botanist Akira Miyawaki, is an urban afforestation technique. It involves planting dense layers of native plant species close together to mimic natural forest structures.

This technique fosters rapid growth and self-sustainability, resulting in forests that grow 10 times faster and are 30 times denser than conventional plantations. Miyawaki forests become self-sufficient in approximately 2-3 years, requiring minimal maintenance.

These small, biodiverse forests are prominently used in urban and peri-urban areas. They serve vital environmental functions such as improving air quality, supporting urban biodiversity, and reducing local heat. The method does not involve genetically modified flora, commercial agriculture, or renewable energy production. Miyawaki forests are widely adopted globally, including in India, for ecological restoration, carbon sequestration, and urban greening.
