This publication gives us the opportunity to showcase the rich heritage, both material and immaterial, of Ksar Ouled Youssef, in the M’Hamid Oasis, in the hope to generate wider awareness of its cultural significance and struggle to survive desertification, sand dunes encroachment and outmigration. It also allows us to show our profound gratitude to the people of the ksar for their unparalleled hospitality, generosity and eagerness to share their traditional knowledge, and make their habitat and way of life known to outsiders like us.
