The 2026 Rich Earth Summit is the 12th annual global gathering advancing circular sanitation for clean water and sustainable agriculture. The Summit explores how nutrients in human “waste” can be reclaimed as a valuable resource for farms instead of becoming costly watershed pollutants, through completing the nutrient cycle. 46 presenters from around the world will share research, storytelling projects, economic strategies, pilot projects, and more. Conservation biologist Joe Roman will present the keynote “Eat, Poop, Die: How Animals Make Our World," based on his book of the same title. View the full Summit schedule and presentation details.  Together, we can pee the change!
