Description of Challenge
Desertification (loss of arable land, forced migration, hunger etc.)Architect Magnus Larsson proposes an innovative, natural way of creating a natural wall out of Sahel dunes.
Solution
Architect Magnus Larsson proposes an innovative, natural way of creating a natural wall out of Sahel dunes to prevent further desertification as an alternative for the green wall – which is undermined by people’s need for fuel. Larsson proposes to use a natural bacteria to solidify parts of sand dunes, turning them into structures. There structures can be both lived in, as well as function as a solid base for plant and tree-growth, greening the desert from within.
