Sugarcane field with controlled burn at sunset in countryside

Controlled burn in a sugarcane field at sunset in São Paulo countryside, a common agricultural practice for sugarcane harvesting.

About this subject

Controlled burning of sugarcane straw is a traditional agricultural technique in Brazil, particularly in São Paulo state, the country's largest sugarcane producer. Performed before manual harvesting, the burn removes dry leaves and venomous animals, making cutting easier and increasing worker productivity. However, this practice generates air pollution and greenhouse gas emissions, and is gradually being replaced by mechanized harvesting in flat areas. The sunset scene highlights the contrast between fire and the orange sky, symbolizing the duality between tradition and modernity in Brazilian agribusiness. Despite controversy, controlled burning is still allowed in sloping areas and under specific weather conditions to minimize the risk of wildfires.

Frequently Asked Questions

Why is controlled burning done in sugarcane fields?

Controlled burning removes dry straw and facilitates manual cutting of sugarcane, also eliminating venomous animals, increasing worker safety and productivity.

Is controlled burning allowed by law?

Yes, but with restrictions. In São Paulo, state law has prohibited burning in mechanizable areas since 2017, only allowing it in sloping regions or with environmental authorization.

What is the environmental impact of sugarcane burning?

Burning releases CO2, particulate matter, and other pollutants, contributing to global warming and respiratory problems. Therefore, there are incentives for mechanized harvesting.
