Fire Dynamics on a Micro-regional Scale: Methodology and application based on free data and softwares

Abstract

Research Purpose: Proposes a methodology for space-time analysis of fires/burn on a microregional scale based on free data from the burning program of INPE – National Institute for Space Research and use of free software. Methodology: The methodological referral covered the reference on the subject, the acquisition of accessible vector and matrix data and records from the INPE fires/burn database. The product validation was referenced in the publications of INPE fires and reports. Findings: The results revealed that of the 209 burn detected in the South Coast Microregion of the State of Espírito Santo, Brazil between 2009 and 2019, 60.3% or 126 occurred in land uses of "Pasture" and in "Temporary Crops". It also showed 4 registers inside the Conservation Units - UCs and 26 the damping zone of 3 km of the UCs. The monthly analysis indicated the highest records in the months marked by low rainfall and dry indices, with the highlight for July to September, concentrating 45.9% or 93 of the 209 occurrences. Originality/Value: The use of the methodology offers an important contribution to control and monitoring actions, which can be applied in municipalities or regions that need studies of this nature, because it considered the occurrences in the territory from reference data of accessible fires, charting with free software places most susceptible to disasters of this nature.
