Arid regions are highly vulnerable with respect to environmental and particularly hydrological changes. Data scarcity for most of these areas (such as Egypt and the most of Middle East) is a great challenge for hydrogeological investigation at practical scales. Moreover, climate change will exacerbate groundwater-related problems by reduction in recharge rates in some areas, increased reliance on groundwater resources due to decrease in the reliability of surface-water sources, saltwater intrusion due to sea-level rise, and deterioration of groundwater quality by increased flushing of urban and agricultural wastes.
Erik J. Schaffernicht is a PhD candidate in meteorology at the Institute for Geophysics and Meteorology of the University of Cologne, Germany.
He is member of the project Palaeoclimate and Palaeoenvironmental Reconstructions Using a Computational Regional Environmental Modelling System (Project E6) of the Collaborative Research Centre 806 (CRC806), Our Way to Europe.
The Chew Bahir basin is located in southern Ethiopia. It is a tectonic graben, which is part of the East African Rift System (EARS). Its position close to the Omo Valley, which is considered to be the source region of the anatomically modern human (AMH), makes it an interesting target for interdisciplinary research.
Many archaeologists associate the appearance of Homo sapiens and modern behavior with the Middle Stone Age of Africa. Over the years numerous models have been developed to explain how and why modern humans left Africa and dispersed throughout the world. The majority of these models are based on skeletal and genetic data as well as climatic data, while paradoxically very few incorporate archaeological data.
11,000 years ago, at the beginning of the Holocene, today’s hyper-arid Sahara desert was dotted with large and small lakes, savannah and grassland and in some regions even humid tropical forest. Due to a strengthened African monsoon triggered by strong orbital forcing i.e. summer insolation, more humid conditions compared to today, prevailed in Northern and Central Africa.
I am a member of the CRC 806 in project B3 as research assistant since 2011. Since September 2013 I am working on my PhD (funded by the German National Academic Foundation), in which I am analyzing changes of fossil diatom communities during the Holocene in sediment cores from Lake Kinneret (Israel; Southeastern Mediterranean) and Laguna de Medina (Spain, Western Mediterranean).
“How often have you sat through a presentation and felt bored, uninspired or even confused? Delivering a great presentation can be a challenge – especially if English is your second language. In your career as an academic or researcher giving presentations is a major and important part of your role. With this one and half day presentation skills workshop you will pick up some tips on how to improve your presentation style and practice in a constructive environment”

Lesley-Anne Weiling is a native English speaker and comes from Ireland. She is a partner in Write English, a Cologne based business specializing in helping people improve their English communication skills in both writing and presenting.
She graduated from Queens University Belfast and began her career in the IT industry in London. Working in the high pressure environment of sales and marketing Lesley-Anne experienced first hand the value of good presentation skills. As a senior manager, she often had to give presentations to multicultural teams and large audiences. Her role involved mentoring junior team members and coaching them to deliver successful presentations.
The project C3 investigates limnological archives on the southern Iberian Peninsula to unravel past environmental and climatic conditions of the late Quaternary.
Dr. Petr Kuneš (Charles University, Prague) will offer a course on quantitative palynology during his stay in Cologne:
Suggested topics covered by the course (R-project):
- Basic statistics and multivariate data analysis in palynology/assemblage data: rate of change analysis, rarefaction, indirect ordination (PCA, DCA), direct ordination (RDA, DCCA – applied in Canoco program)
- Quantitative vegetation reconstruction using pollen data: Theory behind and application of the ERV model (calculation of pollen productivity estimates) and Landscape Reconstruction Algorithm (REVEALS and LOVE models to reconstruct regional and local vegetation estimates)
- Application of modern analogue technique to assemblage data, reconstructing climate, transfer functions
Forests have undergone gradual change since their formation after the end of the glacial. Until today, these forests have been influenced by humans for at least eight millennia being gradually transformed into today’s agriculture landscape. However, to the simple disappearance of woodland we have to account with various forest management regimes, which profoundly altered woodlands’ structure and species composition. Continue reading
