Sustainable Organic Integrated Livelihoods or SOIL is an American nonprofit developmental aid organization co-founded by Sasha Kramer and Sarah Brownell in 2006. Its goal is to develop integrated approaches to the problems of poverty, poor public health, agricultural productivity, and environmental destruction in Haiti. SOIL's efforts have focused on the community-identified priority of increasing access to ecological sanitation, where human wastes are converted into compost. More than 20,000 Haitians are currently using SOIL ecological sanitation toilets.
