Five years is a long period for project‐funded research and non‐palaeolimnologists may forgive me when I first recognize the fact that additional five varves (annual laminations) and tree rings have accumulated during the project time extending our geoarchives of landscape change. Obviously, our Virtual Institute is documented not only in our publications, PhD theses, outreach and other commonly used evaluation parameters, but and measurable also in our archives. These five varves and tree rings probably are amongst the best studied and we made significant steps forward in understanding how they formed and how environmental signals were transferred into our archives. We are gathering here to present our main achievements and share them with the scientific community, but we also want to make use of this symposium to address new challenges for our research and discuss novel approaches and methodologies to address these challenges. The overarching goal of landscape research is to better anticipate regional impacts of future global change in order to create intelligent adaptation strategies to limit negative consequences of such changes for our societies. However, landscape evolution is the result of complex coupled processes working at different time scales. Anticipating future developments will not be possible by simply extrapolating trends of the last few decades because of inherent legacies and landscape controlling mechanisms that function on longer time scales. We, therefore, need to integrate information from the past in a holistic and time‐integrating approach. However, the concept of learning from the past is easy to be claimed, but its realization in detail still is challenging and not straightforward to accomplish. Information from the past is recorded in different natural archives including lake sediments, tree rings, palaeo‐soils and geomorphological features. All of them have been intensively studied within ICLEA. Each of these archives contains information about different environmental aspects at different time resolution and a comprehensive picture about past landscape evolution and its driving mechanisms requires integrating all available information. In order to be able to achieve this, we first must know how to reliably interpret the data from our archives in terms of past changes. Proxy data are for geoscientists like hieroglyphs for archaeologists for which a dictionary is lacking. In ICLEA, we implemented the task to write such dictionary for our proxy data. We made good progress in proxy calibration as this will be presented during our symposium. However, we also disclose some fundamental challenges that we would like to discuss in the next three days. One of these concerns is the question of a non‐analogue situation today due to the comprehensive human impact that might not allow the transfer of observed climate – environment – proxy relations far back in time. Even without human impact the proxy responses to climate and environment changes might not always have been stationary on longer time scales. In ICLEA, we have demonstrated that STR 17/03.

DOI: 10.2312/GFZb103-17037 4 ICLEA Final Symposium 2017 ‐ GFZ German Research Centre for Geosciences, Potsdam, Germany we have to seriously consider these limitations in proxy calibration, but that there are potential solutions to deal with these limitations in a differentiated way and, ultimately, minimize them. In ICLEA our focus particularly is on terrestrial geoarchives, because they have the advantage over marine and ice cores of providing regional climate and environment information directly from the human habitat. As above mentioned, this advantage implies the problem of possible direct and indirect human‐induced modifications of proxy signals in these archives. On the other hand, this can provide new windows into the way of life of pre‐historic societies which did not deliver written documents. Exploiting our archives with respect to past human activities is a major chance especially for palaeolimnological research in the next decade. The main objective and challenge will be to disentangle human and natural signals in these archives. In contrast to the progress in climate and environment proxies, we still have a great demand in developing proxies for human activity like, for example, specific fire proxies and human biomarkers. Some first attempts in this direction have been developed in ICLEA that will presented during this symposium. We will present our main results in an integrated way according to the main themes of relevance rather than following the classical work package ordering based on archive type and disciplines. The order of sessions partly reflect the development of research in ICLEA during course of the project. We started with a strong focus on deciphering the role of natural variability and its driving mechanisms and increasingly considered man – climate – environment interactions as a highly intriguing topic not only for the industrialization period, but even for the prehistoric period. Session 1: Abrupt and High Frequency Climate Variability since the Late Glacial Session 2: Recent change and instrumental observations Session 3: Integrating time‐scales and regional synchronization Session 4: Man ‐ climate ‐ environment interactions We have invited international experts for each of these themes to give keynote presentations and further stimulate our discussions. In addition to the oral sessions, we give room for detailed discussions in front of posters as in our previous workshops. Finally, we keep a good ICLEA tradition to discuss new results not only in lecture rooms but also in front of the objects that we are investigating, i.e. during field excursions.
