Definition by Regeneration International on 16 February 2017:
“It describes farming and grazing practices that, among other benefits, reverse climate change by rebuilding soil organic matter and restoring degraded soil biodiversity – resulting in both carbon drawdown and improving the water cycle.”
(Remark: This definition will continue to evolve as research and practice emerge and reveal what the health of soils is, and how to sequester carbon and build topsoil.)
Regenerative farming goes beyond organic or sustainable. It not only stresses on “not harming the land” but also enhancing its productivity by understanding, respecting and mimicking the mechanisms of nature on farmland. Nowadays, agriculture, without doubt an artificial system, has developed a generally accepted but flawed paradigm to control and monitor the nature, rather than understanding the deep-rooted causes of different undesirable symptoms we observe in the field.
To be more concrete, regenerative farming means
(i) restoring carbon back to soil through the most important natural process: photosynthesis, and
(ii) enriching soil life in terms of diversity and quantity
It is a win-win-win situation where farmers harvest more good food, consumers enjoy safe tasty food full of nutrients and there is a good chance that we reverse climate change by storing and stabilizing carbon in the soil. With healthy soil, farmers can grow plants in a stress-free environment without synthetic chemicals that poison the food and degrade the soil, in return, plants thrive and produce good harvest of high-quality nutrient-dense food.
Here is a well-written overview by Jack Kittredge that we highly recommend to everyone who has the will to take a regenerative step in agriculture:
If you are a farmer, or you have practical experiences of farming, you may wonder how to farm or manage your garden towards a regenerative direction. Here we raise some of the practices that we think are the most crucial to start with. Please be reminded that this is not intended to be an exhausted list and we definitely have to adjust according to farm scale, local resources, weather and climate differences, etc.:
