Explanation:

Invented by and named after Japanese botanist Akira Miyawaki, the ‘Miyawaki Method’ is a unique technique to grow forests.

• Under the approach, dozens of native species are planted in the same area, close to each other, which ensures that the plants receive sunlight only from the top, and grow upwards than sideways.
• During early period, the plantings compete with each other for space and access to light and water—a battle that encourages much faster growth. In conventional afforestation techniques, 1 meter of growth per year is considered the norm. In the Miyawaki method, trees grow about 10 times faster. Once stabilized, the forest is left to flourish, forevermore, on its own without further interference.

Hence both statements are correct.
