Adam Izdebski
Ancient historian and psychologist by education, I work at the intersection of history and the palaeo-sciences, or the sciences of human history. In particular, I focus on how the data produced within the different branches of the environmental and earth sciences may contribute to our understanding of premodern societies and economies. I am interested in how they functioned as holistic socio-ecological systems combining cultural and "natural" components; how they reacted to enviornmental stress, be it climate fluctations, disease events or other phenomena. I tend to disbelieve catastrophist visions and explore the ways in which the study of the past may be relevant for the current challenges of the planetary crisis. I work on these issues together with the colleagues from the Independent Max Planck Research Group "Palaeo-Science and History" which I lead at the Max Planck Institute for the Science of Human History in Jena.
Although not restricted to these areas, my work usually focuses on the Eastern Mediterranean and Central Europe.

How did humans and the environment impact each other in the medieval Eastern Mediterranean? How did global climatic fluctuations affect the Byzantine Empire over the course of a millennium? And how did the transmission of pathogens across long distances affect humans and animals during this period?
This book tackles these and other questions about the intersection of human and natural history in a systematic way. Bringing together analyses of historical, archaeological, and natural scientific evidence, specialists from across these fields have contributed to this volume to outline the new discipline of Byzantine environmental history.

This paper examines the evidence for climatic changes in the Eastern Mediterranean for the period 200-800 AD and offers hypotheses on the role of climatic fluctuations in the societal developments that occurred in this region at the end of Antiquity. The geographical focus of the paper includes Anatolia and the Levant, two major regions of the Eastern Roman Empire that are rich in environmental, historical and archaeological data.
- Use of palaeoclimate, palaeomodels, historical, palaeoenvironmental, archaeological data.
- Complex medieval Byzantine socio-economic system.
- Climate was a contributing factor to the socio-economic changes of the medieval Byzantium.
- Byzantine socio-economic system vulnerable to climatic changes only with external pressures.

At the beginning of the Medieval Climate Anomaly, in the ninth and tenth century, the medieval eastern Roman empire, more usually known as Byzantium, was recovering from its early medieval crisis and experiencing favourable climatic conditions for the agricultural and demographic growth. Although in the Balkans and Anatolia such favourable climate conditions were prevalent during the eleventh century, parts of the imperial territories were facing significant challenges as a result of external political/military pressure. The apogee of medieval Byzantine socio-economic development, around AD 1150, coincides with a period of adverse climatic conditions for its economy, so it becomes obvious that the winter dryness and high climate variability at this time did not hinder Byzantine society and economy from achieving that level of expansion. Soon after this peak, towards the end of the twelfth century, the populations of the Byzantine world were experiencing unusual climatic conditions with marked dryness and cooler phases. The weakened Byzantine socio-political system must have contributed to the events leading to the fall of Constantinople in AD 1204 and the sack of the city. The final collapse of the Byzantine political control over western Anatolia took place half century later, thus contemporaneous with the strong cooling effect after a tropical volcanic eruption in AD 1257.
We suggest that, regardless of a range of other influential factors, climate change was also an important contributing factor to the socio-economic changes that took place in Byzantium during the Medieval Climate Anomaly. Crucially, therefore, while the relatively sophisticated and complex Byzantine society was certainly influenced by climatic conditions, and while it nevertheless displayed a significant degree of resilience, external pressures as well as tensions within the Byzantine society more broadly contributed to an increasing vulnerability in respect of climate impacts.
Our interdisciplinary analysis is based on all available sources of information on the climate and society of Byzantium, that is textual (documentary), archaeological, environmental, climate and climate model-based evidence about the nature and extent of climate variability in the eastern Mediterranean. The key challenge was, therefore, to assess the relative influence to be ascribed to climate variability and change on the one hand, and on the other to the anthropogenic factors in the evolution of Byzantine state and society (such as invasions, changes in international or regional market demand and patterns of production and consumption, etc.). The focus of this interdisciplinary study was to address the possible causal relationships between climatic and socio-economic change and to assess the resilience of the Byzantine socio-economic system in the context of climate change impacts.

and Paphlagonia – since Late Antiquity till the end of the Middle Byzantine period (6 th-13th c. AD).
Most of the conclusions presented in this paper are based on palynological material, as potentially
relevant archaeological and textual evidence is scarce and poses serious interpretational problems.
In order to properly use the pollen data collected by Bottema, Woldring and Aytuğ, new age-
depth models were constructed with the use of clam age-modelling software, on the basis of the
radiocarbon dates obtained by the original investigators. Thus, the key turning points in the history
of northern Anatolian landscapes in the Byzantine era were identified. First, the transition from Late
Antiquity to the Middle Ages, which meant some diminishment of complex agricultural activities
in the very north of the region and their collapse in the south; second, relatively short “pasturing
phases” which seems to have occurred in many areas in the early medieval period; third, the Middle
Byzantine agricultural expansion halted most probably by the Turkish invasion; finally, the late
medieval recovery of agricultural activities. Unfortunately, as the archaeological evidence is very
inconclusive, almost nothing is known as regards the transformations of settlement which must have
accompanied each environmental change.
ENVIRONMENT AND SOCIETY IN THE FIRST MILLENNIUM A.D.
Conference to be held at
The Society of Antiquaries, London,
Saturday 8th October 2016
See document for full programme and booking details
A workshop organised jointyl by the MPI SHH and the University of Jena. All are invited!
The primary aim of the conference is to make a contribution to the ongoing debate concerning the form and content of interdisciplinary research on human-environment dynamics in past societies from prehistory to Late Antiquity. The conference will be an arena for innovative ideas, integrated methods and lessons learnt from current interdisciplinary projects in the Peloponnese and beyond. In answer to the open call for more collaborative research efforts, the conference will host 17 lectures by members of the PELOPS group and invited speakers, presenting well integrated accounts of human-environment interactions in past societies.
The conference will open on Thursday, 6 April, 2017, 7 pm at the Acropolis museum, with a lecture by Michael GIVEN (University of Glasgow), ‘Conviviality of the land: towards a new academic ecology’, followed by a welcome reception at the Swedish Institute at Athens.
The conference will thereafter take place at the American School of Classical Studies at Athens, 7-8 April, 9 am-18 pm.
