The time since land-use transition drives changes in fire activity in the Amazon-Cerrado region

A. F. S. Ribeiro, L. Santos, et al.

This research explores how deforestation and climate change are transforming fire regimes in the Cerrado-Amazon transition, revealing intriguing links between land-use transitions and fire probability. Conducted by an expert team of authors, including Andreia F. S. Ribeiro and Lucas Santos, this study highlights the critical role of frontier age in understanding fire activities, especially during droughts. An eye-opening look at the ecology of fire!

Abstract

Deforestation and climate change are expected to alter fire regimes along the Cerrado-Amazon transition. This study modeled fire probability as a function of time since land-use transitions (frontier age) from 1986 to 2020. Results show that deforestation increased fire activity before and after land clearing, especially in the Amazon. Agricultural intensification reduced fire probability, but deforestation-related fires remained a significant factor, particularly during droughts. Incorporating frontier age into fire modeling is crucial due to the ecological implications of changing fire regimes.
