The project will develop an innovative new model to examine the pivotal role of anthropogenic wetlands in the long transition to agriculture in the Levant. Remarkably, while this transition has been explored in some detail, we still do not have a good grasp on the long-term developments and causes of the origins of agriculture, mainly due to a lack of direct botanical evidence.

The Late Bronze Age (LBA) and Early Iron Age (EIA) in southwest Asia saw major socio-political transformations, including the rise and fall of the Hittite, Kassite and Neo-Assyrian empires. Alongside socio-political and economic instability, climatically induced droughts are among the most frequently cited causes for the collapse of these states. However, direct evidence for the impact of droughts on agricultural systems is virtually absent from these periods, rendering hypotheses that see climate change at the heart of the crises hypothetical.

The aim of H-E Interactions is to investigate how increasingly anthropogenic wetland landscapes, and the reliable resources within those environments, influenced the evolution of plant-food production and the origins of agriculture through the Final Pleistocene and into the Early Holocene (ca. 23-8 ka cal. BP).

Around 1,200 years ago, archaeological evidence suggests pre-existing pastoralist societies that had been present in some parts of eastern Africa since c. 5,000 BP experience significant cultural and economic change. Materials signs of these include the uptake of iron smelting technologies, new ceramic styles, and changes in food production. In the following centuries, the region also experienced several significant shifts in climate, alternating between periods of increased rainfall and extended droughts.

This project is a response to calls to build long-term sustainability and resilience into pastoral social-ecological systems in sub-Saharan Africa through provision of deep histories of human-environment interactions. It focuses on collecting and analysing archaeological and related data on the responses of pastoralist communities inhabiting the Laikipia and Leroghi plateaus, northern Kenya, to cycles of extreme drought and enhanced rainfall over the last millennium.

Igbo-Ukwu is a famous archaeological site in southeastern Nigeria. Excavated by Professor Thurstan Shaw in the 1960s, the site was settled over a thousand years ago. The materials from the site were unlike anything yet found in West Africa at the time. This discovery brought to our consciousness that Igbo-Ukwu represented a prosperous society that had established a complex social structure by the 9th century CE and had significantly interacted with the wider world through interregional and intercontinental exchange and trade.
