Indigenous fire brigades record their traditional ecological knowledge via map-based apps.\r\n\r\n\u201cThe true owners of the knowledge, with field experience about the way fire behaves, are the Indigenous people in those areas,\u201d said Talita Oliveira Tarlei De Freitas, an environmental analyst at Prevfogo, which is part of the larger Brazilian Institute for the Environment and Renewable Natural Resources (IBAMA).\r\n\r\n&nbsp;"},{"acf_fc_layout":"image","image":648842,"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"Prevfogo\u2019s fire brigade training includes the use of an app called the National Wildfire Information System (Sisfogo), which was built using GIS technology. Sisfogo makes it simple for firefighters to collect wildfire information and incident details, which are displayed on a dashboard for decision-makers.\r\n\r\nFirefighters use Sisfogo on their phones and tablets to see the fuel load maps of green and dry vegetation and coordinate the suppression of unwanted fires. This information helps manage controlled burns during the wet season and contributes to a greater understanding of the land.\r\n<h3>Reinforcing Indigenous Rights<\/h3>\r\nBrazil is also taking measures to prevent illegal fires along the Amazon\u2014those started by settlers who burn the forest to clear land for farming and grazing. When Brazilian president Luiz In\u00e1cio Lula da Silva won reelection in 2022, he pledged increased protections and support for the rainforest and Indigenous stewards of the land. Since then, thousands of non-Indigenous people have been removed from the two native territories that had seen the greatest amount of deforestation. The removal of illegal settlers reduces environmental stress on the land Prevfogo manages and eliminates a persistent source of fires.\r\n\r\nPrevfogo works within Indigenous territories called quilombos and land reform settlements in integrated fire management activities.<em> [Quilombos are settlements dating from Brazilian colonial times that were organized by fugitive slaves.]<\/em> Of the 99 fire brigades Prevfogo has trained and maintained since 2009, more than half are composed of Indigenous people and one is composed entirely of women.\r\n\r\nEach tribe has a unique cultural connection to fire, using it in various ways for rituals, land management, and hunting. The Indigenous fire brigades spread their fire knowledge through the Sisfogo app so that all can learn what elders have passed down through generations.\r\n\r\n\u201cIndigenous firefighters work in their own territory, which is very important for us because they have a natural relationship of protection,\u201d Freitas said.\r\n<h3>Depleting Fuels Before the Dry Season<\/h3>\r\nTo reduce fuels, brigades conduct prescribed burns in May at the beginning of the driest season, which typically lasts through October. The areas considered most vulnerable to fire are carefully evaluated, and burning only occurs where authorized. For this work, the center\u2019s GIS tools help with public awareness.\r\n\r\n\u201cWe need to inform the community and gain approval,\u201d Freitas said. \u201cMaps and imagery help us show the risk and convince them that we\u2019re there to partner and work with them. They may need to sacrifice a small piece of their land as part of a prescribed burn for the bigger picture of reduced wildfire risk in the future.\u201d\r\n\r\nFor a short period that began in 2001, Brazil\u2019s government banned controlled burning by tribes but soon reversed the policy. Researchers have learned that many of Brazil\u2019s biomes depend on fire and controlled burns reduce fire intensity and damage. Controlled burns that spread slowly\u2014called cold fires because they naturally die out in the early evening when temperatures decrease\u2014give animals and insects time to flee. The flames don\u2019t reach the treetops and are not intense enough to destroy mature trees or shrubs.\r\n\r\nGIS maps visually communicate the brigade\u2019s strategy for its controlled burns. \u201cWe use maps to explain where we plan to burn and to demonstrate how and why we will conduct the operation in a certain way,\u201d said Luiz Pacheco Motta, an environmental analyst and developer at Prevfogo who is working on Sisfogo.\r\n\r\n&nbsp;"},{"acf_fc_layout":"image","image":648852,"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"<h3>Stopping Destructive Fires<\/h3>\r\nWhen faced with wildfire, tribes in the affected region share maps to communicate and take strategic actions. Within the Sisfogo app, they can adjust data capture forms and dashboards as needed. \u201cThey can share their thoughts, their feelings, their perceptions of the world using GIS tools and maps,\u201d Freitas said.\r\n\r\nThe value of collecting and sharing tribal knowledge extends beyond the immediate needs of firefighters. Government ministries, agencies, and academics benefit from the data and shared awareness.\r\n\r\n\u201cOne of Sisfogo\u2019s biggest challenges is to adapt the traditional use of fire to climate change,\u201d Motta said. \u201cTo this end, GIS technology with spatiotemporal data and Indigenous land-use records provides the right way to respond to this challenge.\u201d\r\n\r\nPrevfogo can now visualize and analyze wildfire data to see patterns, compare incidents in space and time, and monitor hot spots. The insights could provide answers about wildfire conditions and incidents, which can inform global efforts to reduce disasters.\r\n\u201cEveryone is watching Brazil for environmental issues, deforestation, and wildfires right now,\u201d Freitas said. \u201cIt\u2019s important for us to show the world what we\u2019re doing, how we prevent wildfires, and how we manage them.\u201d\r\n\r\n&nbsp;"},{"acf_fc_layout":"image","image":648862,"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"Prevfogo\u2019s monitoring and combat division (DMC), where Sisfogo developers work, relies on global GIS collaborators who share knowledge and techniques to better face the challenges of global warming.
