Guest Column - This week, we welcome King Charles to Kenya, on his first visit to the Commonwealth since his Coronation. In Nairobi’s Karura Forest, the lungs of our city that my mother, the late Professor Wangari Maathai and so many others fought to save, he will honour her legacy for which she was awarded a Nobel Peace Prize in 2004. I, along with many others, will have the honour of sharing Karura Forest, the oasis it represents for our city, thanks to the foresight of brave friends of this forest over 30 years
