After fifteen years of reconstruction in a relatively peaceful environment spanning the years 1990 to 2004, Lebanon has experienced successive violent political events resulting from complex entangled internal and external struggles. Since 2002, a collaborative endeavor between French and Lebanese researtchers has resulted in producing two versions of the Atlas of Lebanon, now adapted and translated in English. The richly illustrated book displays original maps and infographics to provide a rare vision of the country. It highlights the new main legacy of the civil war and the reconstruction, and underscores the new challenges linked to the unfolding of the Syrian crisis and its consequences on Lebanon, particularly because of the massive influx of Syrian refugees in the country. The atlas assesses the fragile economy, the environmental degradation, climate change and the failures of public infrastructure. The book ends with the analysis of the mutations of the local territorial management, which is marked by the retreat of the state, if not its marginalization, and the rise of other actors, notably municipalities, local powers and also civil society organizations.
