In simple terms, slash and burn is a method where farmers cut down vegetation, let it dry, and then burn it. The ash enriches the soil with nutrients, creating a temporary patch of fertile ground for crops like maize, cassava, or rice.
After a few seasons, the soil loses its fertility—and the plot is abandoned to regenerate for a decade or more. The farmer then moves to a new patch and repeats the cycle. Yes, it’s mobile, not lazy.
Think of it as a natural reset button for the land, but one that requires a lot of patience and space. In traditional settings, it worked beautifully for thousands of years.
Why Do People Still Do This?
Because it’s incredibly efficient for communities without access to tractors, fertilizers, or irrigation. The ash provides an instant nutrient boost, and the clearing opens up sunlight for crops.
Around 200 to 500 million people worldwide still rely on some form of shifting cultivation. Most live in tropical regions—the Amazon, Central Africa, and Southeast Asia.
It’s not a primitive choice; it’s a pragmatic one, born from deep knowledge of local ecosystems. Many indigenous cultures have refined the practice over centuries, rotating fields like clockwork.
