Abstract: Across a 1000‐km stretch of the River Nile, from the 1st Cataract in southern Egypt to the 4th Cataract in Sudan, many hundreds of drystone walls are located within active channels, on seasonally inundated floodplains or in now‐dry Holocene palaeochannel belts. These walls (or river groynes) functioned as flood and flow control structures and are of a type now commonly in use worldwide. In the Nile Valley, the structures have been subject only to localised investigations, and none have been radiometrically dated. Some were built within living memory to trap nutrient‐rich Nile silts for agriculture, a practice already recorded in the early 19th century C.E. However, others situated within ancient palaeochannel belts indicate construction over much longer time frames. In this paper, we map the distribution of these river groynes using remote sensing and drone survey. We then establish their probable functions and a provisional chronology using ethnoarchaeological investigation and the ground survey, excavation and radiometric dating of the structures in northern Sudan, focusing on the Holocene riverine landscape surrounding the pharaonic settlement of Amara West (c. 1300–1000 B.C.E.). Finally, we consider the historical and economic implications of this form of hydraulic engineering in the Nile Valley over the past three millennia.

Abstract: Agricultural practices in northern Sudan have been changing rapidly but remain little documented. In this paper we aim to investigate changes to crops grown in living memory and their uses through interviews with Nubian farmers on the island of Ernetta. By exploring cultivation and crop processing practices, together with associated material culture and foodstuffs, we also seek to explore how agricultural and food heritage are connected, and to better understand reasons for crop changes. Several cereals and pulses that were previously important subsistence crops are now grown as comparatively minor crops. The replacement of the sagia (waterwheel) by diesel pump irrigation, the introduction of commercial crops, and the reduction of the annual flood have led to fundamentally new cropping patterns within household farms. At the same time, each species has its own narrative and timing of change. Shifts in crops grown are paralleled by transitions in foodways, associated material culture, and land use. The project is timely, as much of the information about past crop uses resides in the memories of elderly farmers. The findings highlight the broader global need to document endangered memories of cropping patterns, traditional ecological and food knowledge, including local terms for foods and crops.
