Theres two types of slash and burn.
One is cyclical where the forest returns as part of the cycle.
Its actually the most environmentally friendly type of Agriculture.
Its really embedded in natural pricesses and biodiversity
The other is non cyclical.
It advances across the landscape burning away ecosystems never to return
It leaves behind erosion, poverty and a simplified weedy landscape.
Step by step. Id like to keep some burning in this system, particularly to turn spiny or diseased biomass into Biochar.
BioChar would be a great way to process the material into useable product.
