Sugarcane field with controlled burn at sunset in countryside

Scene of a sugarcane field under controlled burn at dusk in São Paulo's countryside, a regulated agricultural practice.

About this subject

Controlled burning of sugarcane is a traditional agricultural practice in Brazil, especially in São Paulo state, the country's largest sugarcane producer. The procedure involves setting fire to the dry leaves of the plant before manual harvesting, making cutting easier and reducing risks of accidents with venomous animals. Although controversial due to pollutant emissions, controlled burning is legally permitted in areas where mechanized harvesting is unfeasible, such as sloped or small-scale fields. Since 2007, the sugarcane industry has signed protocols to gradually eliminate this practice by 2031, replacing it with mechanized harvesting. Sunset in São Paulo's countryside, with its orange sky and mild temperatures, is a common time for these burns, as wind and humidity conditions favor fire control. The burning sugarcane field creates a dramatic contrast with the horizon, capturing a transitional phase in Brazilian agriculture between traditional and modern methods.

Frequently Asked Questions

Why is controlled sugarcane burning done at dusk?

At dusk, wind and humidity conditions are more favorable for controlling the fire, reducing the risk of uncontrolled spread.

Is controlled sugarcane burning legal?

Yes, it is legally permitted, but it is being gradually phased out by environmental protocols, with a deadline set for 2031.

What is the environmental impact of controlled burning?

It emits air pollutants, such as particulate matter and greenhouse gases, but is considered less impactful than uncontrolled burning and is regulated to minimize damage.
