Raw earth and the Mediterranean.

The Mediterranean, 22 countries bordering the same sea. A climate and land that gave us olive oil, wine, bread but also raw materials to build. Here, like everywhere, men and women used what they had under their feet: EARTH and stone.

Earth is a raw material used for building materials. It is a major component of constructional cultures around the world (more than a third of the world's population lives in raw-earth habitat). There are construction systems that have been exclusively or partially composed of raw earth in all countries of the Mediterranean basin for millennia.
From the second half of the 20th century, the use of raw earth for construction tends to disappear in favour of industrial materials. This evolution of building practices has led to phenomena whose consequences are disastrous from an ecological and social viewpoint as well as cultural.
