“In their free-flowing form, large rivers like the Tana are among the most productive, life-giving ecosystems on the planet. These natural supermarkets continue to feed hundreds of millions of very poor people each and every day.
Many fish species wait for floods to swim out onto a river’s floodplain, where they spawn prolifically. When a fish spawns on a floodplain, its offspring will have many advantages over other fish born in the river itself. The water spilling onto a floodplain during floods is enriched with nutrients, helping young fish to grow. The drowned vegetation of the floodplain harbors a bounty of insects to feed upon, and provides places where newborn fish can hide from bigger fish and other predators. Rivers with large numbers of floodplain-spawning fish produce far more fish for people to eat than those without floods and floodplains.”
