Abstract

In Southeast Asia, Cambodia has the highest rate of wildfire, and during the early 2000s, fire activity has dramatically grown. Since wildfires are frequently multidimensional, it is still challenging to assess the relative significance of each component. Assessment of the environmental condition is highly dependent on forest fire, climate, biological, and biophysical aspects investigation using Google Earth Engine (GEE) and MODIS data. This study created a framework for identifying concerns connected to forest fires in Cambodia between 2005 and 2023. There were 975.90 km² of observed afforestation and 35561.33 km² of deforested area due to the forest fire. The annual average rainfall observed between 2005 and 2023 shows 9.76 mm decreased while evapotranspiration increased by 24.85 mm. While Cambodia's surface temperature decreased by 2.72 °C, latent heat (LE) increased from 0.14 W/m² (2005) to 0.22 W/m² (2023). Surface temperature and precipitation have negative correlation values of −0.48 (2005), −0.55 (2010), −0.54 (2015), −0.52 (2020), and −0.38 (2023). Forest fires have had a major impact on Cambodia's ecosystem and climate. This study enhances the present comprehension of the causes of forest fires in Cambodia, and the methodological framework created has great potential for application to other regions of the world that are prone to forest fires.

期刊介绍： Physics and Chemistry of the Earth is an international interdisciplinary journal for the rapid publication of collections of refereed communications in separate thematic issues, either stemming from scientific meetings, or, especially compiled for the occasion. There is no restriction on the length of articles published in the journal. Physics and Chemistry of the Earth incorporates the separate Parts A, B and C which existed until the end of 2001. Please note: the Editors are unable to consider submissions that are not invited or linked to a thematic issue. Please do not submit unsolicited papers. The journal covers the following subject areas: -Solid Earth and Geodesy: (geology, geochemistry, tectonophysics, seismology, volcanology, palaeomagnetism and rock magnetism, electromagnetism and potential fields, marine and environmental geosciences as well as geodesy). -Hydrology, Oceans and Atmosphere: (hydrology and water resources research, engineering and management, oceanography and oceanic chemistry, shelf, sea, lake and river sciences, meteorology and atmospheric sciences incl. chemistry as well as climatology and glaciology). -Solar-Terrestrial and Planetary Science: (solar, heliospheric and solar-planetary sciences, geology, geophysics and atmospheric sciences of planets, satellites and small bodies as well as cosmochemistry and exobiology).
