The complexity of Neolithic population movements and their interpretation through material culture have been the subject of archaeological research for decades. One of the dominant narratives proposes that groups from the Starčevo-Körös-Criş complex spread from the central towards the northern Balkans in the Early Neolithic and eventually brought the Neolithic lifestyle into present-day Hungary. Broad geographical migrations were considered to shape the continuous expansion of Neolithic groups and individuals. However, recent archaeological research, aDNA, and isotope analyses challenged the synchronous appearance of specific material culture distributions and human movement dynamics through emphasizing communication networks and socio-cultural transformation processes. This paper seeks to retrace the complexity of Neolithic mobility patterns across Hungary by means of strontium and oxygen stable isotope analyses, which were performed on a total of 718 human dental enamel samples from 55 Neolithic sites spanning the period from the Starčevo to the Balaton-Lasinja culture in Transdanubia and from the Körös to the Tiszapolgár cultural groups on the Great Hungarian Plain (Alföld). This study presents the largest strontium and oxygen isotope sample size for the Neolithic Carpathian Basin and discusses human mobility patterns on various geographical scales and throughout archaeological cultures, chronological periods, and sex and gender categories in a multiproxy analysis. Based on our results, we discuss the main stages of the Neolithisation processes and particularly trace individual movement behaviour such as exogamy patterns within extensive social networks. Furthermore, this paper presents an innovative differentiation between mobility patterns on small, micro-regional, and supra-regional scales, which provides new insights into the complex organisation of Neolithic communities.

Extreme weather events and severe flash floods during July 2021 caused numerous deaths and massive ecological disasters across Europe. The regionally overstrained environmental and socio-cultural resilience triggered an intensive discussion about cause and effect, responsibilities and public denouncement, and the financial consequences of climate-induced extreme events. In this article we analyze the flood event by four methodological approaches: (1) hermeneutics, with an analog interpretation of printed newspapers and sources; (2) text mining and natural language processing of digital newspaper articles available online; (3) precipitation and discharge models based on instrumental data; and (4) how the findings can be linked to the historical extreme floods of 1804 and 1910, based on documentary source analysis. These four approaches are used to compare and evaluate their consistency by tracking the course, consequences, and aftermaths of the flood disaster. The study shows a high consistency between the analog, digital, and instrumental data analysis. A combination of multidisciplinary methods and their application to historical events enables the evaluation of modern events. It enables to answer the question of return periods and intensities, which are indispensable for today’s risk assessments and their social contextualization, a desideratum in historical and modern climatology.

Europe witnessed a strong increase in climate variability and enhanced climate-induced extreme events, such as hot drought periods, mega heat waves, and persistent flooding and flash floods. Intensified land degradation, land use, and landcover changes further amplified the pressure on the environmental system functionalities and fuelled climate change feedbacks. On the other hand, global satellite observations detected a positive spectral greening trend—most likely as a response to rising atmospheric CO2 concentrations and global warming. But which are the engines behind such shifts in surface reflectance patterns, vegetation response to global climate changes, or anomalies in the environmental control mechanisms? This article compares long-term environmental variables (1948–2021) to recent vegetation index data (Normalized Difference Vegetation Index (NDVI), 2001–2021) and presents regional trends in climate variability and vegetation response across Europe. Results show that positive trends in vegetation response, temperature, rainfall, and soil moisture are accompanied by a strong increase in climate anomalies over large parts of Europe. Vegetation dynamics are strongly coupled to increased temperature and enhanced soil moisture during winter and the early growing season in the northern latitudes. Simultaneously, temperature, precipitation, and soil moisture anomalies are strongly increasing. Such a strong amplification in climate variability across Europe further enhances the vulnerability of vegetation cover during extreme events.

To understand the connectivity in human–landscape ecosystems, a multidirectional concept of landscape transformation, sociocultural development, and human response cycles needs to be considered. In this context, societal decision-making is controlled by the ecosystem’s functionality; the human perception, experience, memory, and tradition; and the individual configuration of landscape components: a conceptual framework that is herein referred to as landscape affordances. In contrast to defining environmental components as passive resources, the concept of landscape affordances entails dynamic and processual feedbacks of an individual and the environment in the moment of mutual interaction—thus actively integrating human ingenuity in the production of landscapes, biological processes, and sociocultural patterns. This article contextualizes the concepts of landscape affordances and functional ecosystem connectivity to evaluate human behavioural patterning and the production of landscapes in a methodological landscape archaeological approach.

The transportation of Chalcolithic and Early Bronze Age ivory raw materials and artefacts across the Mediterranean has been in the focus of archaeological research for over a century now. However, tracing the flow of ivory has mostly been restricted to traditional theoretical models of raw materials distribution deriving from socio-culturally centred considerations. Environmental conditions, potential transportation networks and dissemination routes have not yet been considered decisive for the spread of ivory raw material from the African shores and the eastern Mediterranean towards the Iberian Peninsula. Implementing computational environmental and archaeological modelling, we present a fully reproducible quantitative approach to estimate potential communication and transportation networks based on environmental covariates. We deploy a Network Analysis model and a predictive model based on Least Cost Path density to propose a potential land- and sea-based movement corridor for the western Mediterranean Basin that could have enabled the cultural spread of resources during the 3rd and 2nd millennia BC. Using the presented model and the open-source data underlying the analyses, distribution patterns of multiple material resources from different chronological subsets or regions can be developed, which will contribute to understanding prehistoric human patterns across the Mediterranean.
