Across the world, cities are confronting a common challenge.

As populations grow and development intensifies, urban areas are becoming hotter, noisier and increasingly disconnected from nature.

Concrete surfaces absorb heat, biodiversity declines, and green spaces often struggle to keep pace with expansion.

In response, an unconventional form of afforestation pioneered in Japan is gaining global attention.

Known as the Miyawaki method, it transforms small plots of land into dense native forests capable of supporting wildlife, improving local environmental conditions and restoring fragments of lost ecosystems.
