recommendations! Published in 2018 at "Remote Sensing of Environment"

DOI: 10.1016/j.rse.2018.04.009

Abstract: Abstract Tropical forest disturbance (such as selective logging and fire) along with deforestation have significant contributions to the carbon source due to land-use change and anthropogenic CO2 emissions, and thus envisioned by United Nation's REDD+… read more here.
