About This Project

Written in the Soil explores how an ancient farming community along the Silk Road sustained agriculture for centuries in a water-limited environment. Building on our recent peer-reviewed research at Ravat (Kyrgyzstan), we will investigate ancient irrigation and soil management using geoarchaeology. Funding will support local fieldwork, Kyrgyz archaeologists and student participation, helping us uncover how this remarkable landscape once worked.

Ask the Scientists

What is the context of this research?

For centuries, farming communities along the Silk Road depended on carefully managed irrigation systems to survive in dry environments. Yet we still know surprisingly little about how these systems functioned or how they remained productive over long periods.

Ravat, in southwestern Kyrgyzstan, preserves one of the best-preserved ancient agricultural landscapes in Central Asia. Its irrigation canals, fields and archaeological soils still contain evidence of past farming practices. In our recent peer-reviewed study, we demonstrated that these soils preserve microscopic evidence of irrigation, cultivation and long-term land management. Rather than answering our questions, these results revealed new ones.

This project builds directly on that research. By combining archaeology and geoarchaeology, we aim to reconstruct how water, soils and farming practices interacted to create a sustainable agricultural landscape more than 1,500 years ago.

What is the significance of this project?

Ravat offers a rare opportunity to investigate how an ancient farming community successfully managed water and maintained agriculture over many generations in a semi-arid environment. Although the ancient irrigation system is no longer fully functional today, its canals, cultivated fields and archaeological soils are exceptionally well preserved, preserving evidence that has disappeared from most ancient agricultural landscapes in Central Asia.

This project will improve our understanding of long-term interactions between people, water and landscape while contributing new data to the archaeology of the Silk Road. By reconstructing how past societies adapted to water scarcity over centuries, our findings may provide valuable long-term perspectives on sustainable land and water management. The project also strengthens collaboration between researchers in Kyrgyzstan and Europe and trains the next generation of Kyrgyz archaeologists.

What are the goals of the project?

The main goal of this project is to reconstruct how the ancient agricultural landscape of Ravat functioned and how its inhabitants successfully managed water in a semi-arid environment. During the field season, we will document the irrigation system, map archaeological features using drone surveys, and collect undisturbed soil samples from ancient fields and associated iron-smelting areas. These samples will be analysed using soil micromorphology and geochemical analyses to identify microscopic evidence of irrigation, cultivation, fertilisation and long-term soil management. By integrating these results with drone mapping and archaeological observations in a GIS environment, we aim to reconstruct how water, farming practices and landscape development interacted over time, providing new insights into sustainable agriculture along the Silk Road.
