Brazil’s dry‑season fire‑prevention drive, intensified by El Niño, has seen widespread bans and massive resource mobilization. In Mato Grosso, a fire prohibition period ~~from 1 July to 30 November 2026~~ is in effect across the Amazon, Cerrado, and Pantanal biomes. To support this, the state launched a R$134 million operation involving 85 vehicles, aircraft, and 150 contracted brigadists. Additionally, Mato Grosso signed an Environmental Commitment Agreement to transition industrial biomass from native forests to planted sources by 2035. In Mato Grosso do Sul, an environmental emergency decree was issued to address heightened drought risks. Preventive measures included prescribed burns in the Ivinhema River Floodplain and Pantanal parks to reduce biomass. Meanwhile, Campo Grande launched the “Agosto Alaranjado 2026” campaign to curb urban fires. Regional efforts have expanded ~~significantly.~~ significantly, with Goiás ~~declared~~ declaring a 120-day environmental emergency ~~with a total fire ban, while~~ and Tocantins ~~suspended all~~ suspending controlled-burn permits until 31 October. In Maranhão, Operation Maranhão Sem Queimadas utilizes Starlink satellite technology and drones. In Pará, the Operation Fênix partnership uses real-time satellite monitoring. permits. As the dry season progresses, authorities report escalating ~~damage. In Mato Grosso, extreme drought~~ damage and ~~heat have heightened wildfire~~ extreme weather risks. By late August, the state recorded 1,489 heat spots between 16 and 22 August, leading to severe air pollution that exposed approximately 710,000 people to fine particulate matter levels exceeding WHO recommendations. In ~~Jangada, fires have destroyed over 120 hectares of sugarcane and caused cattle losses. In Goiás, fires destroyed over 14,000 hectares of vegetation near Serra Dourada State Park. In~~ Acre, wildfire activity saw a massive surge ~~was recorded~~ in ~~late August,~~ August 2026, with ~~173~~ heat spots ~~identified between 27 and 28 August—more than tripling~~ increasing by approximately 770% compared to July. Data from the ~~state’s previous single-day record~~ National Institute for Space Research (Inpe) shows 487 fire spots were recorded in August, accounting for 83.4% of the ~~year.~~ state’s total annual occurrences. The municipality of Feijó has been most heavily impacted, while air quality in Rio Branco has deteriorated, with PM2.5 concentrations reaching levels nearly 2.8 times the annual concentration recommended by the World Health Organization. Fire departments are reporting a rise in emergencies linked to extreme weather conditions. In Codó, the Military Fire Brigade noted a 22% increase in vegetation fire calls. In the Vale do Juruá region, specifically near Cruzeiro do Sul, authorities issued alerts following a fire that burned approximately 50,000 square meters. To manage risks during September—a critical month for fire propagation—the military is conducting ‘Operation Controlled Fire’ across five municipalities. Fire departments are also intensifying educational campaigns to prevent improper fire use from escalating into large-scale environmental damage.
