Natural Sciences and archaeology: Collaborative research for 'Entangled Africa'
Research on past climate and ecosystem changes, land-use patterns and subsistence strategies, as well as landscape transformations is an important component of several ‘Entangled Africa’ projects. On May 11, 2021, members of the Program’s ‘Natural Sciences’ Working Group met to discuss further collaborative research and the management and publication of research data.
Connected virtually from their home universities or home offices in Berlin, Cologne, Münster and Frankfurt, the meeting began with brief updates on the progress of work in each project. It was impressive to see the progress that has been made despite the restrictions imposed by the pandemic in the last year. It was also the first opportunity to hear the new colleague in the ClimCellMed project, Mansour Mdawar, who presented the dendrochronological work on juniper trees from Turkey and Lebanon. In addition, Jana Eger-Karberg (InterLINK project) and Tim Karberg (DFG funded project Wadi Abu Dom Investigations), who are working on geospatial information from northern Kordofan, Sudan, were welcomed to the group.
- Spread and use of crop plants
- Vegetation maps
- The ‘Rain forest crisis’ and beyond
- Medieval Climate Anomaly
The second part of the meeting was dedicated to the discussion and exchange about the possibilities of data curation and management. Following the F.A.I.R. data principles, several Cultivated landscapes and DeGree datasets are being prepared for upload to the Neotoma database platform. Following the November 2020 migration of the database and the recent memorial event for the late Eric Grimm, the data upload is now picking up speed. A first pollen data set (EMIW566) is already available in the system. More palynological data and the Chad Basin charcoal datasets will follow soon.
In addition, the web services of iDAI.welt are used. First images of charcoals and their site Mege at Lake Chad can already be viewed in iDAI.objects/Arachne. A possible repository and exchange platform for the data generated by remote sensing is the iDAI.geoserver. The iDAI.chronontology service can be used for chronological information and the linkage with material culture, for example at Mege. The Learning through connecting project team encourages all participants to contribute relevant data to this flexible “time-space-volume” to facilitate collaboration and the identification of connections within the SPP.
The outcome of the DFG-review of projects which applied for a second phase of funding will now be critical to the implementation of the planned collaborative research and data management work. A next meeting is thus scheduled for fall 2021, when the decision will be pubished.
