(Sensuous) Ways of Seeing in Stone Town, Zanzibar: patina, pose, punctum
This study introduces a novel approach to interpreting the Ranchhod and Rohit Oza vernacular photography collection from Stone Town, Zanzibar (1930–present), challenging conventional historical or cultural readings. By focusing on the medium's characteristics—patina, pose, and punctum—the research offers a 'sensuous' framework that emphasizes incompleteness and visual perception over narrative completeness. This method shifts the interpretation of the Capital Art Studio (CAS) archive away from illustrative history toward an experiential, sensory engagement with the images. The study draws on John Berger's Ways of Seeing to recontextualize how photography is viewed, curated, and analyzed, providing a fresh lens for understanding vernacular visual culture in UNESCO-listed Stone Town.
Electromagnetic Shielding Effectiveness of Historic Buildings: The Heritage Stone Town of Zanzibar
Historic buildings constructed with traditional materials, such as coral stone, mud, and mangrove poles, exhibit significant electromagnetic shielding effectiveness (SE), comparable to renowned structures from the Roman Empire. This finding highlights the potential of these materials in mitigating health and security risks posed by electromagnetic radiation (EMR) from modern wireless devices. The study tested buildings in Stone Town of Zanzibar, demonstrating that their construction techniques and materials can effectively shield EMR, offering insights for future building designs to incorporate traditional materials for enhanced shielding properties.
Calcium Carbonate Production, Coral Cover and Diversity along a Distance Gradient from Stone Town: A Case Study from Zanzibar, Tanzania
Coral reefs near Stone Town, Zanzibar, exhibit significantly lower calcium carbonate production (8.47 ± 4.37 kg CaCO₃ m⁻² yr⁻¹), coral cover (52.4 ± 13.9%), and biodiversity compared to those farther away or within marine protected areas, where values peak at 16.90 ± 9.70 kg CaCO₃ m⁻² yr⁻¹, 67.4 ± 8.7% cover, and higher diversity (H′ = 1.74 ± 0.20). This gradient suggests that human activities—such as fishing pressure, pollution, unregulated tourism, and anchoring—severely degrade reef health, while protection measures mitigate these impacts. The study highlights the critical role of distance from urban centers and management regimes in shaping coral community structure, with reefs closest to Stone Town dominated by stress-tolerant species like Porites lobata and P. rus. These findings underscore the need for targeted conservation efforts to preserve Zanzibar’s reef ecosystems.
Producing a World of Remains in Indian Ocean Africa: Discrepant Time, Melancholy Affect and the Subject of Transport in Capital Art Studio, Stone Town, Zanzibar
Capital Art Studio in Stone Town, Zanzibar, employs a unique visual idiom that challenges the heritage industry's narrative by re-presenting the city as a 'melancholy palimpsest.' This approach simultaneously evokes Zanzibar's past as an 'island metropolis' while resisting its consignment to history. The studio's photographic archive reveals discrepant temporalities, offering surfaces for self-fashioning that contrast with those of other postcolonial studios. By framing the past within a neoliberal global order, the studio articulates a time that was both cosmopolitan and commodifying, providing a nuanced perspective on Zanzibar's complex historical interface between the Indian Ocean world and continental Africa.
Tourism employment and local residents’ engagement in the conservation of the built heritage in Zanzibar Stone Town in Tanzania
Tourism employment significantly influences local residents' engagement in conserving Zanzibar Stone Town's built heritage, acting as a key moderator between attitudes toward conservation and the intention to conserve.
