In June, the study of a team of researchers published in the journal Nature Plants alerted about the gradual disappearance for a decade of the vast majority of the oldest baobabs in Africa *. Eight of the thirteen older of them are partially or died totally in the past 12 years. A spectacular and very disturbing phenomenon when we know that baobabs are trees that can live for thousands of years.

Africa is the continent with the most baobabs in the world, with a particular concentration in Madagascar. Only on the “red island”, no less than six species of baobabs on the existing nine are identified. The best known is the Adansonia digitata, or African baobab, found in many countries of the continent.

If the gradual disappearance of baobabs does not leave me indifferent, it is because they occupy a special place in African societies. “The tree of life” is sacred to many of our cultures. In West Africa, the baobab is often called the “palaver tree” because of its social function. In many African villages, being under the baobab means gathering and exchanging to solve a problem the community is facing.

Beyond this social function, the baobab also has a central place in the African flora. From a scientific point of view, it is a tree with many virtues and uses: it feeds, offers products of construction, heals … The baobab even serves as a water tank in some cases. In the arid regions of Madagascar where the Mahafaly people live, the inhabitants dig the trunks of the baobabs into rainwater reservoirs. Thanks to this know-how which is transmitted from generation to generation, a baobab-tank can hold up to 9,000 liters of water, enough to cover the water needs of a family for four to five months.

And yet, baobabs are disappearing in Africa, largely because of climate change, according to the researchers. This hypothesis is supported by the fact that it is in southern Africa, a region particularly affected by climate change, that these disappearances of savanna giants have been most often noted.

The death of baobabs speaks volumes about the more global challenges facing Africa. While Africa is the continent that produces the least greenhouse gases, it is also the continent that is the most victim of climate change. In a context where multilateralism is being undermined by national selfishness, African states must succeed in mobilizing the other countries of the world for better global governance in favor of the preservation of the environment and better management of global public goods.

Some African legends say that God gave this strange form to the baobab in order to connect the sky to the earth, thus becoming “the roots of heaven”. But above all, the roots of the baobab are buried in the land of an Africa in full transformation. It is up to us to make sure that despite these great political, economic, cultural and environmental developments, our baobabs remain firmly rooted in African soil, as are our traditions and our culture.
