Nairobi, Kenya:  It has been a long, tiring and dusty journey across north eastern Kenya on a mission to witness first-hand the effects of the drought that has left millions on the brink of starvation. With me on this trip is UNICEF Sweden Goodwill Ambassador Liza Marklund and Swedish photographer Martin von Krogh. Together we have travelled from Dadaab, the world’s largest refugee camp, to Liboi near the Kenya-Somalia border and their journey ends in Wajir, a drought stricken district in northern Kenya. But for me this journey is far from over.
