Nigeria is struggling to end open defecation, but a grassroots campaign is trying to change that

Open Defecation Free Nigeria works to stop people from disposing of human waste in public areas by building public toilets. The organization has built 66 so far and manages a group of volunteers who educate residents about the dangers of public defecation. Encouraging behavioral change is key to ending the practice of open defecation. Fundraising and the sale of private household toilets funds the public toilets, which are tailored to the needs of a community. Most contain a biodigester system that turns waste to liquid or compost manure, which can last for decades and is easy for communities to maintain.
