Bolivian Wildfires: A Global Crisis And Challenge

Bolivia has been experiencing some of the worst wildfires in over a decade, with over 3 million hectares of land burned so far this year. The blazes have been exacerbated by a prolonged drought and a recent heatwave, which have turned vegetation into tinder. The fires have spread across several ecosystems, including the Pantanal wetlands, the Chiquitano forest, Beni savanna and Amazon rainforest areas. The consequences have been severe, with over 1.3 million acres of land charred, crops and grazing lands destroyed, and 25% of the large fires burning in protected areas. The Bolivian government has declared a national emergency and called for international aid to help tackle the fires. The situation in Bolivia is part of a wider issue of wildfires in the Amazon region, which have been raging for several weeks and affecting Brazil and Ecuador as well. The fires are thought to be caused by a growing amount of farmland and deforestation, leading to a rise in temperatures and decreasing rainfall, which increases the risk of wildfires. The Amazon is currently in its worst state in 50 years, with over ten thousand species at high risk of extinction due to the fires and deforestation.

Bolivia has recorded the largest number of wildfire outbreaks in 14 years, with 3 million hectares of land burned

Bolivia has recorded the largest number of wildfire outbreaks in 14 years, with 3 million hectares (7.5 million acres) of land burned. This has resulted in a national emergency being declared, with the country's defence ministry stating that this will allow them to "have more agile and effective support from friendly countries and from international cooperation".

The wildfires have had a devastating impact on the country, with Reuters reporting that "walls of flames engulfed tracts of dry land" in the Bolivian region of Concepcion. The government has called for international aid, with the country's firefighting teams stretched thin.

The wildfires have been exacerbated by the effects of climate change, with South America experiencing a record drought that has dried out vegetation across the region. Bolivia's wildfire season usually peaks in August and September, with the season lasting until December. As a result, the total figure for 2024 is expected to rise sharply.

The blazes have also had a significant impact on the country's cultural heritage, with the lowland region's distinctive wooden churches under threat. Additionally, Indigenous communities that rely on the land for agriculture and livestock have been severely affected, with water and food supplies disrupted.

The Bolivian wildfires are part of a larger issue affecting South America, with neighbouring Brazil also experiencing major blazes. The Amazon rainforest, which spans several countries in the region, including Bolivia, has been particularly hard hit, with the worst start to the fire season in two decades.

Wildfires in Bolivia have been exacerbated by a prolonged drought, which has parched landscapes and turned vegetation into tinder

Bolivia has been experiencing severe wildfires, with 2024 marking the largest number of outbreaks in 14 years, with 3 million hectares of land burned already. Neighbouring Brazil is also suffering from a torrid fire season, with blazes in major cities and the Amazon rainforest off to their worst start in 20 years.

The wildfires in Bolivia have been exacerbated by a prolonged drought, which has parched landscapes and turned vegetation into tinder. The drought has been caused by warm ocean temperatures in the tropical Atlantic Ocean, which tend to shift weather patterns and divert moisture away from South America. This has been further exacerbated by El Niño, which has shifted rainfall patterns, and reduced humidity from deforestation.

The consequences of the fires have been severe, with the government reporting that more than 1.3 million acres have been burned, dangerously close to several towns, and causing widespread damage to crops and grazing lands. Bolivia's Ministry of Defense reported that nearly 3,825 firefighters and 45 military units played a role in fighting wildfires in 2023.

The fires have also had an impact on the country's distinctive wooden churches, with the blazes burning artifacts and buildings. In addition, the smoke from the fires has led to smog and poor air quality in some areas.

Bolivia's lowland plains have been highly impacted by smoke transported from the Amazon and Cerrado biomes

The Bolivian lowland plains were highly impacted by smoke transported from the Amazon and Cerrado biomes due to their proximity to the fire foci and lower altitude. The smoke impacted the city of Santa Cruz, exceeding the World Health Organization's daily PM10 limit in June-September. The smoke also had a lower impact on the cities of La Paz and Cochabamba, with PM10 exceedances mainly due to local sources.

The Amazon biome covers parts of Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, Guyana, Suriname, and French Guiana. The biome contains blackwater and whitewater flooded forests, lowland and montane terra firma forest, bamboo and palm forest, savanna, sandy heath, and alpine tundra. The Cerrado biome, on the other hand, is characterized by dry forests, grasslands, and wetlands and spans across Argentina, Bolivia, and Paraguay.

Bolivia's wildfire season usually peaks in August and September, but officials are already preparing to continue fighting fires until the year's end

The blazes are being driven by a prolonged drought, which has parched landscapes in Bolivia and Brazil. The drought has been exacerbated by warm ocean temperatures in the tropical Atlantic Ocean, which tend to shift weather patterns and divert moisture away from South America. The consequences of the fires have been severe, with more than 1.3 million acres of land burned in Bolivia, dangerously close to several towns and causing damage to crops and grazing lands.

Bolivia's wildfire season usually peaks in August and September, but the country often experiences fires until the end of the year. In 2023, for example, 25% of the large fires in Bolivia burned in protected areas during October. In 2020, Bolivia experienced fierce fires throughout August, September, and October, which charred large areas and emitted smoke that darkened skies over the region.

The country's worst October for fires on record was in 2020, when the blazes continued until December. Bolivia saw its highest number of October, November, and December fire outbreaks ever recorded that year, with 12,453, 9,426, and 1,347 outbreaks, respectively.

Bolivia's Santa Cruz was the most affected city by wildfires, where PM10, CO and AOD increased between 1.3- and 3.9-fold in September compared to April

Bolivia has been experiencing severe wildfires, with the country recording the largest number of outbreaks in 14 years, with 3 million hectares (7.5 million acres) of land burned already this year. The situation is particularly dire in the lowland region of Santa Cruz, where PM10, CO and AOD increased between 1.3- and 3.9-fold in September compared to April.

Santa Cruz is the most affected city by the wildfires due to its proximity to fire foci and lower altitude. The smoke has caused widespread damage to crops and grazing lands, and has even burned dangerously close to several towns. The fires have also impacted the air quality in the region, with PM10 levels exceeding the WHO daily limit in June–September.

The Bolivian government has declared a state of emergency and called for international aid to combat the blazes. As of early September, blazes had torn through more than 10 million hectares of Bolivia, or roughly 9% of the country's total area. The situation is expected to worsen, as peak fire season is still ahead, and drought conditions have intensified the fires.
