Both natural and managed ecosystems fall under nature-based solutions: efforts to protect, manage, and restore ecosystems for the purpose of human and biodiversity benefits. Benefits include harnessing healthy ecosystem(s) for their potential, safeguarding biodiversity, and delivering ecosystem services. In practice this means sustainable natural solutions, techniques, projects, and initiatives which deliver results. In other words, solutions that simultaneously protect and harness natural ecosystems (habitats), benefiting humans and nature itself in the process. An example of an ecosystem which would benefit from nature-based solutions is land that has been damaged by mono-cropping and intensive chemical-input agriculture as characterized by the Green Revolution. There is evidence that agricultural practices can change which species of mycorrhizal fungi are present, for example intensive agriculture versus natural systems.
