Extractive agriculture

If you look at the conventional way farming is done across the world, and if we are completely honest with ourselves, it is a largely extractive process. For example, conventional agriculture uses a large amount of fossil fuels, and products of fossil fuels. Some examples are:


Renewable agriculture

A more common term for renewable agriculture is regenerative agriculture.


Commit to the process

On every farm I have been to, the farmer and I have been able to identify multiple opportunities from these two steps. They have been practical, viable options for each farmer in their own context. Shifting a farm to regenerative, sustainable practices is not straightforward, nor does it happen overnight.
