food for 9 billion

Aquaponics uses 90 percent less water than conventional fish ponds, and the plants grow faster and need less space than they would in the soil. It’s also nearly climate-proof, since it doesn’t rely on the weather.

Here, Charles Mulamata feeds nile tilapia, which are native to Uganda and popular with consumers. Because they are herbivorous and thrive in crowded conditions, they are well suited to aquaponics.
