The "Miyawaki method" is well known for the:
- A.Promotion of commercial farming in arid and semi-arid areas
- B.Development of gardens using genetically modified flora
- C.Creation of mini forests in urban areas
- D.Harvesting wind energy on coastal areas and on sea surfaces
Correct answer
Explanation
The correct answer is C, Creation of mini forests in urban areas. The Miyawaki method grows dense, fast-growing native forests on small plots of land, which suits crowded cities.
The method was developed by the Japanese botanist Akira Miyawaki. Many native species of trees and shrubs, often three or four saplings per square metre, are planted close together in prepared soil. Because the plants compete for sunlight they grow quickly, and the patch becomes a self-sustaining forest in a few years. Indian cities have used it to raise urban green cover, absorb dust and support birds and insects.
A is wrong because the method is about forests, not commercial farming in dry areas. B is wrong because it uses native species, not genetically modified plants. D is wrong because it has nothing to do with wind energy.
Exam tip: Miyawaki = Japanese botanist Akira Miyawaki, dense native mini forests on small urban plots.
