In Yaoundé, Cameroon, the rapid urban expansion has led to a significant loss of green spaces, with wooded areas dropping from 28.6% to just 5.4% since 1984. Volunteers like Jean-Baptiste Tchengang are stepping up to counter this trend by promoting small gardens and community workshops on composting and local plant preservation. Tchengang has trained around 300 people, helping them create gardens on abandoned plots. Climate specialist Jean-Marie Essoh emphasizes the importance of trees, stating, "They absorb rainwater, slow runoff and help hold the soil together," highlighting their role in climate adaptation.
