- W2001497801 abstract "Clearing of native forest for plantation expansion is a significant component of land use change in many tropicalregions. The continuing expansion of plantations has many environmental consequences, including the loss andfragmentation of habitat, alteration of nutrient cycling processes, reduction in environmentally sequestered carbon,increased soil erosion and land degradation, and loss of biodiversity. The primary goal of this research was todevelop and test remote sensing methods to detect the expansion of plantations in the southern part of the LaoPeople’s Democratic Republic (PDR). We used Landsat satellite imagery acquired between 2003 and 2012.Principal component analysis (PCA) was applied to three Landsat temporal image pairs (2003-2006, 2006-2009 and2009-2012) to identify areas of change. Change identification accuracy was evaluated by comparison against 1,240random sample locations which had been independently classified from Google Earth imagery from 2006 and 2012.It was found that one of the principal components detected change in areas of plantation in the study area, withproducer's accuracy of 92% and user's accuracy of 79%. This method was relatively easy to implement, involved noimage purchase costs, and could be used by ecologists or forestry managers seeking to monitor forest loss orplantation expansion." @default.
