Fire Prediction in Southeast Asia
نویسنده
چکیده
L and fires in Southeast Asia have increased dramatically over the past 30 years due to changes in land use and population density, draining of swamp forests, etc.. In 2015, Indonesian fires alone are estimated to have emitted as much carbon dioxide as Indias annual fossil fuel usage, and to have caused around 12,000 premature deaths. The massive negative environmental and health impacts have prompted increasing interest from regional governments in better quantifying fire risks and identifying land management strategies. One of the major contributing factors is the equatorial Asian peatlands, which is one of the worlds biggest carbon sinks. However, regional-scale investigation of peatland hydrology is made difficult by the location’s inaccessibility of peat forests. Therefore, in this project, we will use machine learning to predict local fire risks from remote sensing satellite data over the tropical peatlands of Borneo, Sumatra, and Peninsular Malaysia in 2015, one of the worst years. The input to our algorithm is remote sensing data collected over seven features– soil moisture, vegetation optical depth, specific humidity, temperature, precipitation, potential and actual evapotranspiration over 0.25 x 0.25 spatial grids in Southeast Asian peatlands. We then use multinomial logistic (Softmax) regression to output a predicted fire risk class. The objective of the study will be to do better than the already existing fire index predictor which is said to have an accuracy of 50%.

متن کاملEl Niño and health risks from landscape fire emissions in Southeast Asia
Emissions from landscape fires affect both climate and air quality1. In this study, we combine satellite-derived fire estimates and atmospheric modeling to quantify health effects from fire emissions in Southeast Asia from 1997 to 2006. This region has large interannual variability in fire activity due to coupling between El Niño-induced droughts and anthropogenic land use change2,3. We show th...
متن کاملCurrent Fire Regimes , Impacts and the Likely Changes – IV : Tropical Southeast Asia
The Southeast Asian region is experiencing some of the world’s highest rates of deforestation and forest degradation, the principle drivers of which are agricultural expansion and wood extraction in combination with an increased incidence of fire. Recent changes in fire regimes in Southeast Asia are indicative of increased human-causd forest disturbance, but El Niño–Southern Oscillation (ENSO) ...

متن کاملIn the line of fire: the peatlands of Southeast Asia.
Peatlands are a significant component of the global carbon (C) cycle, yet despite their role as a long-term C sink throughout the Holocene, they are increasingly vulnerable to destabilization. Nowhere is this shift from sink to source happening more rapidly than in Southeast Asia, and nowhere else are the combined pressures of land-use change and fire on peatland ecosystem C dynamics more evide...
