The Sahara, now perceived as a vast arid desert, conceals traces of a past when it was a lush environment. This reality is illuminated by the climatic evolution that has shaped not only this region but also the entire planet over millennia.

According to a report by DW, the Sahara has experienced periods of greenery, thus testifying to the profound climate changes that have influenced its ecosystem. Geological studies reveal that wetter conditions allowed a diverse flora to thrive in this region once rich in biodiversity.

Scientists agree that these transformations are not solely the result of recent events. As indicated in the report published on the eve of the UN Climate Action Summit in 2019, global climate organizations highlight a growing gap between the goals of combating global warming and observable reality. This gap underscores the urgency to act to preserve threatened environments, including those like the Sahara.

In parallel, the issue of critical minerals is gaining increasing importance in the environmental debate. These resources are essential for the global energy transition, but their extraction and use raise major ecological concerns. Resource-rich African countries must navigate between economic development and the preservation of their fragile environment.

Previous dispatches from the editorial team have also mentioned the scarcity of natural resources on the African continent. Water, for example, is becoming a precious commodity in many regions affected by desertification and climate change. The case of the Sahara perfectly illustrates this dynamic where environmental history is marked by cycles of drought and moisture.

Awareness of these issues is crucial. According to experts, understanding the evolution of the Sahara and its former periods of greenery could provide insights for better managing current resources and anticipating the future impacts of climate change.

The Sahara is not just a desert; it is a reflection of past struggles against climate change. Its verdant remnants remind us that the Earth has undergone upheavals far greater than those we know today. For future generations, it is essential to learn from these historical lessons in order to protect our planet.
