Africa is the continent most exposed to fires, accounting for over half of the burned areas and pyrogenic greenhouse gas emissions globally. Fire seasonality in Africa follows the dry seasons, primarily from October to March for the Northern Hemisphere, with a peak in December–January, and from April to October for the Southern Hemisphere, with a peak in August. In 2001, we monitored active fires monthly, observing significant changes based on the seasons. The equatorial and southern regions of Africa showed a higher concentration of fires, less in the north. This variation has been consistent for 21 years, up to 2021. A strong correlation exists between the latitude of African regions and fire abundance. Equatorial countries experience more fires during the period between December and March, while southern countries see more during the other time of year period. Key factors include the accumulation of biomass, which fuels fires during the rainy season, and increasing human pressure, especially due to the need to warm up.

The Quaternary, a period spanning the last 2.58 million years, is crucial for understanding the climatic and environmental dynamics that have shaped the modem planet. This article explores how data specific to Morocco fit into the global context of Quaternary studies, drawing parallels between local and global information to reveal significant trends and features. By examining paleoclimatic, geomorphological, archaeological and palaeobotanical data, the analysis highlights similarities and differences between local and global observations. The results show that Moroccan data, although reflecting global trends, present specificities that enrich the understanding of climatic and environmental processes at the regional level. This integration not only makes it possible to complete global models but also to identify the local impacts of climate change, thus offering a more nuanced view of Quaternary dynamics and the challenges posed by current climate change.
