Five Japanese-inspired urban forests have been planted in Glasgow to mark the Scottish city's role as host of COP26, the U.N. major climate conference.

The so-called tiny forest plantations are based on the work of Japanese botanist Akira Miyawaki, who died earlier this year. He pioneered a method of creating small-scale, dense tree plantations that grow to maturity in just a few decades — a process which typically takes hundreds of years for a natural forest.

The forests were unveiled ahead of the two-week U.N. summit, which concluded Saturday, in an effort to create a positive environmental impact in the host city, with deforestation among the hot topics being addressed at the conference.
