We must build toilets and sanitation systems that work in harmony with our environment. When nature calls, we have to listen and act.
Nature-based solutions (NBS) to the sanitation and water crisis harness the power of ecosystems:
- Composting latrines that capture and treat human waste on site, producing a free supply of fertiliser to help grow crops.
- Human-made wetlands and reed-beds filter waste water before it is released back into water courses.
