Jamie Hewlett will show his new artwork at a climate change exhibition.
The 41-year-old, who is known for his work with animated musicians Gorillaz, has created nine watercolours for the Under Water Colours exhibition.
The works were inspired by a trip to Char Atra in Bangladesh.
Hewlett, who grew up in Horsham and is a former pupil of Tambridge House School and Northbrook College in Worthing, toured the country with Oxfam earlier this year.
Under Water Colour is open from October 17 to 31 at London's Dray Walk Gallery of Truman Brewery.
