Regenerative agriculture, or restorative agriculture, is any agricultural system that results in a net increase of soil fertility and biodiversity and minimizes non-renewable energy usage while producing an economically significant yield.
Regenerative agriculture is in contrast to agro-industrial farming, which is the norm in 21st century agriculture. Agro-industrial farming typically is degenerative to it's environment and relies on depleting natural resources such as energy, while using industrial chemicals to address deficiencies in soil fertility and relying on biocides to control unwanted ecosystem interactions and kill unwanted life-forms/biodiversity.
Regenerative agriculture may also restore damaged ecosystems to a more natural pattern. Regenerative grazing, for example, mimics natural grassland and open forest ecosystems, returning them to a biodiverse and functional state while managing them to produce high yields of food for human use.
