The Black Forest is considered to be a rather unfavorable area, having a short vegetation period, low mean annual temperatures, high precipitation, and a pronounced relief. These conditions do not favor agricultural land use and thus it is widely accepted that people only began using the land intensively during the Middle Ages. In this integrated study 17 soil profiles, two peat bogs and a database of archaeological finds were used to reconstruct past land use impacts on the environment. AMS–14C datings of charcoals, luminescence datings of colluvial deposits, archaeological finds and pollen records indicate land use already during the Neolithic. This pre‐medieval land use might be related to seasonal settlements dominated by pastoralism and the use of wood or bedrock to build settlements and infrastructure or as energy supply. There is new evidence of human activity dating back to the Bronze and Iron Age, which is a discrepancy to the absence of archaeological finds in the direct vicinity of the studied sites. With the beginning of the Middle Ages land use practices changed, most likely with the expansion and intensification of agricultural land use, which coincides with the increasing use of natural resources in the Black Forest. Hence, the main phases of colluvial deposition date to the Middle Ages and Modern Times. Increased contents of As, Cr, Cu, Pb, or Zn in medieval colluvial deposits might indicate smelting or mining, even though there are no known archeological sites pointing to such activities nearby. Whereas the pattern of colluvial deposition in the southeastern Black Forest points to distinct, but local land use in pre‐medieval times and to intensified and widespread land use since the Middle Ages, thick and multi‐layered colluvial deposits indicate intensive land use in the neighboring Baar region since the Neolithic. The different land use patterns of these two regions originate from the rather favorable conditions for agriculture in terms of soils, climate, and topography in the Baar region compared to the unfavorable conditions in the Black Forest.

Colluvial deposits, as the correlate sediments of human-induced soil erosion, depict an excellent archive of land use and landscape history as indicators of human–environment interactions. This study establishes a chronostratigraphy of colluvial deposits and reconstructs past land use dynamics in the Swabian Jura, the Baar and the Black Forest in SW Germany. In the agriculturally favourable Baar area multiple main phases of colluvial deposition, and thus intensified land use, can be identified from the Neolithic to the Modern times. In the unfavourable Swabian Jura increased colluvial deposition began later compared to the more favourable areas in the Baar. The same holds true for the unfavourable areas of the Black Forest, but intensified land use can only be reconstructed for the Middle Ages and Early Modern times instead of for the Bronze and Iron Age as in the Swabian Jura. Land use intensity and settlement dynamics represented by thick, multilayered colluvial deposits increase in the Baar and the Black Forest during the Middle Ages. In between those phases of geomorphodynamic activity and colluviation, stable phases occur, interpreted as phases with sustainable land use or without human presence.

ABSTRACT. Today's global challenges (e.g., food security) are not unprecedented in human history. Starting with the Neolithic transition, the agricultural sector and society underwent several cultural and technological changes and endured natural challenges. These challenges and changes are analyzed by using the adaptive cycle metaphor and the social-ecological system as tools to show the complexity of human-environment interactions and their development. The analysis relies on archaeological, pedological, and botanical research, and demonstrates the importance of interdisciplinary work. Agrarian soil use as a social-ecological system persisted in Central Europe for 7000 years and underwent an adaptive cycle from the Neolithic transition to industrialization. With agriculture's mechanization, a second adaptive cycle started. The resilience of agrarian soil use for thousands of years shows that agriculture, as a human-environmental interaction, is adaptive to change. Understanding past agricultural challenges and changes using archaeological and soil scientific data puts the present development into a new perspective. A cultural perspective on soils might trigger soil protection and sustainable land use in a technical as well as political domain. Applying social-ecological system and adaptive cycle concepts to this interdisciplinary reconstruction of agrarian soil use illustrates their usefulness for archaeology and soil science.

Using the concept of liminality, this paper provides a comparative study of ritual places. The concept was introduced by Arnold van Gennep in his study "rites de passage", in which he differentiated between rites of separation (préliminaires), rites of transition (liminaires) and rites of aggregation (postiliminaires). The main characteristics of liminality were elaborated by Victor Turner: of crucial importance are the temporary dissolution or reversal of existing social structures and the visit of places that are set apart due to their geographical or cultural location. Accordingly, these places enhance the emotional and physical experiences of the individuals participating in the rituals. We discuss case studies from Prehistoric Archaeology, Classical Archaeology and Ethnology: (I) the Heidentor near Egesheim on the Swabian Jura in southwestern Germany, used during the Hallstatt and the La Tène period, (II) the Early Iron Age ritual complex of Francavilla Marittima close to the Ionian coast of Calabria in southern Italy and (III) the recently used pilgrimage site in the Manzhyly-Ata Valley on the shore of Lake Yssyk-Kul in Kyrgyzstan. The comparative analysis focuses on the spatial and material expressions of liminality and its social significance: the history of origin and usage, special forms of artifacts involved in the rituals and the geographical or cultural location. Due to the exceptional nature of the case studies, their location and long (dis)continuous histories of use, they differ from contemporaneous structures. Altogether, the concept of liminality provides new perspectives on ritual sites and how they were embedded in their surrounding landscapes.
