In the search for an alternative, more sustainable construction material, building companies in Ghana and other African countries are reviving an ancient technique called ‘rammed earth’. Daniel Dadzie, a BBC reporter from Ghana, explains how you make it and why it’s seen as a greener option. Architect and academic Kuukuwa Manful explains the history of rammed earth and how European colonial authorities discouraged indigenous African building styles.”
