Yn ogystal â helpu i reoli risgiau llifogydd i eiddo, gall NFM hefyd helpu i hyrwyddo bioamrywiaeth ehangach, ansawdd dŵr a gwella amwynderau, yn ogystal â manteision dysgu ar gyfer y cyhoedd ac awdurdodau rheoli risg.
As well as helping to manage flood risks to property, NFM can also help to promote wider biodiversity, water quality and amenity improvements, as well as learning benefits for both the public and risk management authorities.
