Climate explained: regenerative farming can help grow food with less impact
Troy Baisden Professor and Chair in Lake and Freshwater Sciences, University of Waikato Climate Explained is a collaboration between The Conversation, Stuff and the New Zealand Science Media Centre to answer your questions about climate change. If you have a question you’d like an expert to answer, please send it to climate.change@stuff.co.nz I would like to know to what extent regenerative agriculture practices could play a role in reducing carbon emissions and producing food, including meat, in the future. From what I have read it seems to offer much, but I am curious about how much difference it would make if all our farmers moved to this kind of land management practice. Or even most of them. – a question from Virginia To identify and quantify the potential of regenerative agriculture to reduce greenhouse gas emissions, we first must define what it means. If regenerative practices maintain or improve production, and reduce wasteful losses on the farm, then the answer tends to be yes. But to what degree is it better, and can we verify this yet? Let’s first define how regenerative farming differs from other ways of farming. For example, North Americans listening to environmentally conscious media would be likely to define most of New Zealand pastoral agriculture systems as regenerative, when compared to the tilled fields of crops they see across most of their continent. If milk and meat-producing animals are not farmed on pasture, farmers must grow grains to feed them and transport the fodder to the animals, often over long distances. It’s hard to miss that the transport is inefficient, but easier to miss that nutrients excreted by the animals as manure or urine can’t go back to the land that fed them. Healthy soils Returning nutrients to the land really matters because these build up soil and grow […]
