The evolution of an agrarian landscape. Methodological proposals for the archaeological study of the alluvial plain of Medellin (Guadiana basin, Spain)

Trabajo presentado a la First International Landscape Archaeology Conference (LAC), celebrada en Amsterdam del 26 al 28 de enero de 2010.In this paper we introduce the background, objectives and initial results of a regional research project focused on the evolution of the agrarian landscape in the Medellin alluvial plain (Badajoz province, Spain). From several different fields we face the task of analysing the changing role of this settlement as a political and administrative centre placed at a key point in communications of the Peninsular southwest. At the same time, we assess the methodological challenges of defining distinct territories based on the archaeological record in an area which has been severely affected by geomorphological processes, and which has also been disturbed by intensive agricultural activity in recent years. Firstly, basic criteria for the surface survey are explained. The workflow is explained from the definition of survey areas to the analysis of spatial distribution of finds. Secondly, we will show the preliminary results of the geomorphological interpretation and mapping of the study area. This is the starting point for a suitability model for the analysis of the interaction between factors that determine our perception of surface archaeological evidence. The objective is the elaboration of a map that would help to evaluate the degree of terrain stability, as a means to assess the representativeness of the surface record and potential risks for conservation.Trabajo presentado a la First International Landscape Archaeology Conference (LAC), celebrada en Amsterdam del 26 al 28 de enero de 2010.Peer Reviewe
