  • Descrição: The Tabarit-East tumulus field is a large cluster of funerary monuments in the western Tagant (south ern Mauritania), where fieldwork has long been restricted by security and logistical concerns. In this paper, we use photogrammetry derived from very high-resolution satellite stereo imagery to measure the volumetric geometry of these funerary monuments, in order to quantify labour energetics and calorific intake associated with construction efforts. This is the first time such a study has been attempted on archaeological structures of this size (>3.5m in diameter). Our results indicate that while the smaller tumuli could have been constructed by nuclear family members within a very short time span, the largest monuments would have demanded greater coordination, as we estimate them to have required the mobilisation of more than 200 person/days and over a million kilocalories. We contextualised how past communities may have engaged with these monuments through spatial analyses, such as least-cost pathways and viewsheds. This combined approach demonstrates the potential of remote sensing techniques to facilitate a deeper understanding of cultural heritage in dryland ecosystems. Furthermore, we aim to integrate these desk-based approaches with collaborative, community-centred fieldwork as soon as this becomes a viable option for this region of Mauritania. •First study to use very high resolution satellite imagery to model volumes of small funerary monuments (>3.5m in diameter).•Volumetric data were used to calculate labour energetics and comparative metrics of inequality.•This approach is useful for studying past cultural landscapes where fieldwork is not possible.
