The Ramsar Convention defines wetlands as:
- Lakes and rivers.
- Underground aquifers.
- Swamps and marshes.
- Wet grasslands.
- Deltas and tidal flats.
- Mangroves and other coastal areas.
- Coral reefs.
- All human-made sites including fish ponds, rice paddies, salt pans and reservoirs.
The Living Building Challenge 4.0, A Visionary Path to a Regenerative Future, published by the International Living Future Institute in June 2019, defines wetlands as: ‘Those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas.’
