Natural, cultural and architectural beauties such as to be included in the UNESCO list of world heritage sites . The specialized agency of the United Nations has released the names of 20 works and places in danger due to wars, industrialization, environmental disasters and urbanization.
Among those to be defended, for example, is the Bamiyan Valley, in Aghanistan : an area that houses several fortified Islamic buildings, sacred caves, Buddhist sanctuaries and monasteries. Here, during the civil war, numerous places of worship were damaged. You may remember the outrage around the world, caused by the destruction of two Buddha statues in 2001 by the Taliban.
Also at risk from 2016 is the conservation of the old city of Sana’a, in Yemen . It is a settlement inhabited for more than 2,500 years, whose historic center is characterized by almost seven thousand houses that look like skyscrapers. Built with dried mud bricks, up to five stories high, with facades decorated with geometric shapes, they were partly devastated by bombing by the Arab coalition – led by Saudi Arabia – against the Shiite Houthi rebels in 2015.
Like the other sites in Syria declared a World Heritage Site , the old city of Damascus is also at risk for the civil war that has been going on for years and is devastating the territory. Positioned between Africa and Asia and founded in the third millennium BC, it hosts many Greek, Roman, Byzantine and Muslim archaeological sites and historical monuments.
In Africa, in the Sahara desert, there is the Aïr-Ténéré nature reserve , which extends over 7.5 million hectares in Niger and hosts a vast number of animal and plant species. In 1992 the site was included in the list of “endangered assets” due to the political disorder that allowed poaching to spread.
