Jürg Walther

Manager of the Arab United Emirates Zone.

Through his work, Jürg has many contacts in the Arab United Emirates. During his frequent travels, he was struck by the contrast between industrialization and modernity in the cities and fragility in the natural environments. This realization made him want to commit for biodiversity with NNF.
