The legacy of 1300 years of land use in Jamaica

Despite decades of archaeological research on Jamaica, little is known about how settlers influenced landscape change on the island over time. Here, we examine the impact of human occupation through a multi-proxy approach using phytolith, charcoal, and stratigraphic analyses. White Marl was a continuously inhabited village settlement (ca. 1050–450 cal yrs BP) with large mounded midden areas, precolonial house structures, and human landscape management practices. We have shown that the local vegetation at White Marl was directly affected by human settlement through the use of agroforestry and burning, and suggest that fire was used to modify vegetation. Manioc phytoliths were found throughout human occupation and are broadly associated with increases in evidence for burning, suggesting fire was used to modify the landscape and clear vegetation for crop cultivation. The phytolith assemblages relate to three distinct temporal vegetation phases: (1) the earliest occupation dominated by arboreal vegetation (pre-ca. 870 cal yrs BP); (2) a transition to palm-dominated vegetation (ca. 870–670 cal yrs BP); and (3) the latest occupation representing European colonization associated with a more open, grass-dominated landscape (after ca. 670 cal yrs BP). These transitions occur independent of changes in paleoclimate records, suggesting humans were the dominant driver of vegetation change.Introduction Archaeological context Archaeobotany in Jamaica The White Marl site Materials and methods - Sampling, stratigraphic analysis, and recording - Phytoliths - Phytolith extraction - Phytolith identification, counting, and quantification - Charcoal extraction and quantification Results - Vegetation phase 1: Arboreal-dominated canopy - Vegetation phase 2: Palm-dominated canopy - Vegetation phase 3: Open grassland-dominated landscape - Crops - Burning indicators - Vegetation changes and climate Discussion Conclusio

Future archive

Future Archive brings together artworks, texts, and conversations from the Future Archive artistic research laboratory, led by artist Rut Blees Luxemburg. Future Archive focusses on the four-year construction process of the RCA’s new Battersea campus, designed by architects Herzog & de Meuron opening in 2022. Future Archive explores the construction site in Battersea as a location for field-study, generating diverse artworks including paintings, photographs and billboards; performances, sculptures, videos and publications. The opportunity to work on a construction site provided the artists a productive conduit for exploring urban transformation, memory and the active construction of a future archive. The representation of labour and masculinity; data and ethics; visualisation and material experimentation were key questions of artistic enquiry
