In Makoko, a sprawling slum of Nigeria's megacity Lagos, a floating school capable of holding up to a hundred pupils has since November brought free education to the waterways known as the Venice of Lagos. It offers the chance of social mobility for youngsters who, like most of the city's 21 million inhabitants, lack a reliable electricity and water supply and whose water-based way of life is threatened by climate change as well as rapid urbanisation.

Kevin Russ, a photographer & image moderator for iStockphoto, grew up in Arroyo Grande, California. In 2003, he made the move to Portland, planning to study at Multnomah Bible College. Finding the workload to be minimal, Kevin invested in a camera, filling his free time and finding himself instantly smitten with the craft. A year and a half later, photography had evolved into his full-time job. However, after 4 years of consistent portrait work, Kevin became burnt out and took a step back from photography altogether. Two years later, he picked up the camera again and now spends the majority of his time on the road, exploring & photographing the rustic landscapes & wildlife he encounters.
