Workers fill bags with rough rice harvested from a paddy field in Lampsar, on August 20, 2026. In Senegal, rice and fish are ubiquitous dietary staples and practically a matter of national pride, so growing the two side-by-side is logical, those involved say. The fish eat snails that cause the parasitic disease schistosomiasis, while also fertilizing the rice with their poop. The disease, which has a wide range of symptoms from itchy skin to anaemia or organ scarring, can be treated with medicine. But that doesn't prevent reinfection nor mitigate the time and money lost when children miss school and adults miss work, furthering cyclical poverty.
