The article highlights the impact of climate change and desertification on the date palm trees in Mauritania, particularly in the oasis village of Azougui and M'Heiret, where nearly 20,000 and 6,000 trees have died since the 1980s, respectively. The dying trees, erratic rainfall, and rising temperatures are forcing residents to migrate, threatening their main source of income. The government's efforts to plant trees and improve irrigation systems, along with calls for the construction of a dam, indicate the community's struggle to adapt and find solutions to mitigate the effects of climate change on their livelihoods.
