To successfully protect the wildlife in Gorongosa National Park, biologists like Cesária Huo know to first support the communities that call the park home. Cesária’s latest initiative aims to tap into the economic potential of an unlikely natural resource: bat guano, a valuable fertilizer. Often the collection process can be harmful to local bat populations, so Cesária is partnering with a Mozambican company Guano Moz to sustainably extract and distribute the guano.
