In 2011, a new approach was introduced into the management of heritage on Ilha de Moçambique by the UNESCO World Heritage Centre. Known as the Historic Urban Landscape (HUL) approach, this seeks to expand current understanding of the island’s historic urban heritage, recognising that ‘heritage’ is not limited solely to monuments or the built environment. Importantly, HUL incorporates urban sustainable development within the scope of heritage preservation. Given this, the adoption of the HUL approach has the potential to contribute to ensuring the authenticity and integrity of the built heritage, as prescribed by the 1972 UNESCO Convention, of Ilha de Moçambique, and effectively maintaining the Outstanding Universal Values that resulted in the declaration of the island as a UNESCO World Heritage Site in 1991. This paper discusses how local communities use the resources and heritage available to them and the central role of commerce, and the marketplace, in the heritage landscape of the island. A critical aspect of this is the sale of antiquities, including archaeological items, to tourists. Perspectives developed within the Rising from the Depths (RftD) network recently supported by the Arts and Humanities Research Council (AHRC) UK, with funding from the Global Challenges Research Fund (GCRF), offer positive alternative solutions to overcome this challenging situation. In particular, the network sought to identify how the tangible submerged and coastal Marine Cultural Heritage (MCH) of Kenya, Tanzania, Mozambique, and Madagascar, and its associated intangible aspects, can be utilised to stimulate ethical, inclusive, and sustainable economic growth in the region. Our paper demonstrates how the implementation of the RftD initiative when combined with the HUL approach can help to increase awareness among communities on Ilha de Moçambique about the relevance of their heritage and the need for preserving it while meeting everyday needs.
