Arnhem plants the world’s first ‘urban climate tree’

Arnhem has planted the world's first ever stadsklimaatboom ('urban climate tree') in the Sonsbeekkwartier. This district is experiencing serious heat problems, which are known as the 'urban heat island effect'. The tree will be ceremoniously unveiled by municipal councillor Henk Kok at 8 p.m. on Tuesday 16 September. This will be followed by a mini-symposium on the urban climate in the district in De Hommel community centre.

The urban climate tree has been planted on Graaf Ottoplein. It is a pagoda tree sapling, which in combination with a work of art, will be promoted as an urban climate tree. This initiative of the city of Arnhem (and others) was sparked by the book 'Het weer in de stad' (The weather in the city) by Sanda Lenzholzer (Wageningen University), which was presented last November. In this book, Lenzholzer clearly illustrates how better urban design could be used to improve thermal comfort in towns and cities.

Their stomata release vapour into the atmosphere, which has a cooling effect on the temperature. In addition, trees filter out particulate matter and other forms of air pollution. All in all, trees can have a very positive effect on urban climate."
