Beirut faced with climatic aridificationBeirut, the capital of Lebanon, is currently undergoing a significant deterioration of its air quality. At the same time, water resources appear to be a crucial challenge, especially in late summer. These two environmental problems simultaneously related to regional climatic characteristics, urban planning and anthropogenic activities, are likely to worsen in the middle term. Indeed, the country is starting to feel the early impacts of the climatic developments observed in the Near and Middle East: desertification is spreading, the length of the dry season increasing, rainfall patterns changing, and temperature rising significantly. However, no management policy has yet been implemented in response to such environmental constraints. Quite on the contrary, private initiatives are developing and putting human pressure on resources already under strain: urbanization is becoming vertically and horizontally denser, illegal wells are being multiplied, thus increasing the scarcity of water and pollutant emissions due to road traffic are suffocating the town. In the end, early signs of aridification combined with the lack of environmental management are threatening, especially in terms of water resources, the thus-far privileged position of Lebanon in the arid or semi-arid context.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
