A growing number of people in Cameroon are using an innovative method to integrate fish farming and plant cultivation.
The novel initiative called aquaponics has been introduced in the Central Africa nation by Flavien Kouatcha, a 31-year-old entrepreneur.
He claims this method of cultivation is "twice as efficient" as traditional agriculture methods because it saves water and bolsters the fight against global warming.
Apart from ecology, Kouatcha said he wants to address the problem of high food costs in Cameroonian markets.
"Our goal is to demonstrate that aquaponics can be very useful in Africa. We want to develop much larger units. We are targeting large scales of producers based on these models," he added.
