Influence of timing and spatial extent of savanna fires in southern Africa on atmospheric emissions
TL;DR: In this article, a Landsat path-row scene locations, distributed over southern Africa, were used to quantify the area burned and to understand the coupled role of the timing and the extent of burning on regional emissions.
Journal ArticleDOI
Modeling and sensitivity analysis of fire emissions in southern Africa during SAFARI 2000
TL;DR: In this article, the authors used satellite data for a sensitivity study of regional biomass burning emissions for a number of trace gases and particulates, and found that the differences in the extent and location of areas burned among products generated from Moderate Resolution Imaging Spectroradiometer (MODIS), Systeme Pour l'Observation de la Terre (SPOT-VEGETATION), and Along Track Scanning Radiometer (ATSR-2) data are significant.
Journal ArticleDOI
Spatial variability of images and the monitoring of changes in the Normalized Difference Vegetation Index
TL;DR: In this article, scale variance analysis was used to determine the spatial frequencies present in the images of the Normalized Difference Vegetation Index (NDVI), which is sensitive to vegetation activity.

TL;DR: In this article, the authors show that there are significant additional pressures on existing agricultural land through increased competition from the biofuel sector and the need to elevate feed production, which is being driven by higher levels of meat consumption in low and middle-income countries.
