What to know about Poverty Alleviation

The article discusses research published in Nature Sustainability regarding rice-fish co-culturing in the Senegal River basin. The study suggests that introducing native fish species into rice fields can reduce the prevalence of schistosomiasis by suppressing snail populations while simultaneously increasing crop yields and farmer income.

What happened

Rice–fish co-culturing could help curb schistosomiasis while increasing food production Stephanie Baum Scientific Editor Robert Egan Associate Editor The chronic disease schistosomiasis wreaks havoc on more than 220 million people around the world, with the…

Why it matters

Despite decades of mass drug administration campaigns, schistosomiasis remains one of the world's most widespread neglected tropical diseases.

Common ground

Rice farmers and their families are particularly at risk, as the parasitic worms that cause the disease are spread by freshwater snails found in the standing water of rice fields.
