Wetland restoration activities re-establish wetland hydrology, vegetation and/or functions usually in areas where they existed previously. Wetlands improve water quality by trapping and cycling nutrients and allow for settling of sediments. Wetlands also moderate water flows, reducing downstream erosion. 2
Wetland restoration can often be very expensive and outcomes can be uncertain. Restored wetlands may not achieve the same level of biodiversity or ecosystem services as undisturbed systems.
Scalable to small farms?
Can be combined with agroforestry practices to generate food, fiber or fodder crops.
