Brazil’s Vanishing Wilderness: A Recipe for Disaster
As the world grapples with the devastating impacts of climate change, a recent study has shed light on the alarming rate at which Brazil’s natural areas are disappearing. Over the past four decades, the country has lost an area of native vegetation more than twice the size of France, leaving it more vulnerable than ever to extreme weather events like El Nino.
The Shrinking Amazon
The Amazon rainforest, the world’s largest tropical rainforest, has been a victim of this destruction. Once covering a staggering 79% of Brazil’s territory, native vegetation now accounts for only 65%. The Cerrado savanna, another biodiversity hotspot, has also suffered significant losses. The biggest culprits behind this deforestation are agriculture and livestock farming, which now cover 32% of Brazil’s territory, up from 18% in 1985.
The El Nino Connection
As El Nino, a weather pattern confirmed in June, intensifies towards the end of the year, different regions of Brazil are bracing for droughts, floods, and fires. An analysis by MapBiomas, an environmental monitoring network, has shown that areas where native vegetation has given way to agriculture are more vulnerable to weather extremes during El Nino events. Tasso Azevedo, general coordinator of MapBiomas, explained that deforested areas of the Amazon have experienced a more significant drop in rainfall compared to forested areas during the 2023-2024 El Nino.
Agriculture: The Unintended Consequence
The study highlights the unintended consequences of land-use patterns on climate events. Azevedo noted that “land-use patterns don’t change El Nino itself, but they can alter the impact it has.” He added that the study did not address why agricultural areas experienced more intense impacts from El Nino, but one hypothesis is that removing forest reduces evapotranspiration and local air humidity, leading to rising temperatures and reduced rainfall. El Nino, in turn, amplifies the magnitude of this effect.
The Human Toll
The consequences of this destruction are already being felt. Last year’s floods in the southern state of Rio Grande do Sul left around 200 people dead. The Brazilian Confederation of Agriculture and Livestock (CNA) has warned that a “super El Nino” could impact crops such as coffee, soy, and sugar. With Pacific Ocean sea-surface temperatures forecast to exceed two degrees above average temperatures, the Brazilian government has warned of a “very strong El Nino” this year.
A Call to Action
As the world watches Brazil’s wilderness disappear, it is clear that urgent action is needed to mitigate the impacts of climate change. The study highlights the importance of sustainable land-use practices and the need to protect Brazil’s natural areas. As Azevedo noted, “our land-use decisions can impact our level of vulnerability and determine how intense these climate events will be in the country.” It is time for Brazil to take a stand and protect its precious natural heritage for future generations.
