The Desert Migrations Project is a new interdisciplinary and multi-dimensional collaborative project between the Society for Libyan Studies and the Department of Antiquities. The geographical focus of the study is the Fazzan region of southwest Libya and in thematic terms we aim to address the theme of migration in the broadest sense, encompassing the movement of people, ideas/knowledge and material culture into and out of Fazzan, along with evidence of shifting climatic and ecological boundaries over time. The report describes the principal sub-strands of the project's first season in January 2007, with some account of research questions, methods employed and some preliminary results. Three main sub-projects are reported on. The first concerns the improved understanding of long-term climatic and environmental changes derived from a detailed palaeoenvironmental study of palaeolake sediments. This geo-science work runs alongside and feeds directly into both archaeological sub-projects, the first relating to prehistoric activity and mobility around and between a series of palaeolakes during wetter climatic cycles; the second to the excavation of burials in the Wadi al-Ajal, exploring the changing relationship between material culture, identity and ethnicity across time, from prehistory to the early Islamic period (the span of the main cemetery zones). In addition, some rock art research and a survey of historic period sites was undertaken in the Wadi ash-Shati and Ubari sand sea.
