World Forum 2023 Speakers

Prince Hussain Aga Khan

Wildlife photographer, Focused on Nature

From a young age, Prince Hussain Aga Khan developed a keen interest in conservation, tropical fish, reptiles and amphibians – and began scuba diving at 14. He started travelling to the tropics frequently after high school and began taking photographs of fauna and flora on a trip to the Brazilian Amazon in 1996.

Multiple photographic expeditions, often organized jointly with scientists or professional photographers, have led him to constitute extraordinary archives, covering various geographic areas and types of habitats. He has also captured many marine and terrestrial species.

His international exhibitions aim to inspire admiration for wildlife and the desire to protect it. Collections of Prince Hussain’s photographs have also been published in four books: Animal Voyage (2004), Diving into Wildlife (2015), Fragile Beauty (2022) and The Living Sea (2022). Proceeds from the sale of his books are donated, via Focused on Nature, to shark, cetacean or sea turtle conservation.
