Answer (Detailed Solution Below)

Option 3: Creation of mini forests in urban areas

Detailed Solution

Explanation:

The Miyawaki forestation method is a unique way to create an urban forest and is pioneered by Japanese botanist Akira Miyawaki who in the 1970s, began to plant young native plant species — trees, shrubs, and grasses — in tight groves to restore degraded lands. Saplings planted close together grow rapidly as they compete for light. By planting a native tree assortment, replicating the vegetation layers found in a mature forest, Miyawaki was engineering (and fast-forwarding) the stages of ecological succession by which a degraded plot turns naturally into a forest.

Therefore, option (3) is the correct answer.
