From: Contribution of remote sensing to wildfire trend and dynamic analysis in two of Ghana’s ecological zones: Guinea-savanna and Forest-savanna mosaic

Fig. 11

Mann-Kendall test and Pettitt test plots representing the trend of burned area in (A) the Guinea-savanna ecological zone and (B) the Forest-savanna mosaic ecological zone, as well as the Mann-Kendall test and Pettitt test plots representing the trend of the number of active fires in (C) the Guinea-savanna ecological zone and (D) the Forest-savanna mosaic ecological zone in Ghana, from data compiled during research to characterize the fire regime for these two zones using a remote sensing approach, during the study period 2001 to 2021. Sequential values U(t) are standardized variables that have zero mean and unit standard deviation (solid line; prograde series), and U′(t) are the values computed backwards, starting from the end of the series (dashed line; retrograde series). 95% CI = confidence interval of the intersection points of the prograde and retrograde curves
