CCA – Climatic Change in the Alps: 10´000 years of climatic and human impact in the Sivretta Massif between the Paznaun Valley (Austria) and the Lower Engadine (Switzerland) (2010-2013)
Project Description and Objectives
Understanding today’s climatic change and its
impact on human societies is dependant on the accurate knowledge on historical
and prehistorical interactions between man and nature. In a highly sensitive
mountainous region such as the European Alps even small, microclimatic
alterations may have huge impact in terms of subalpine settlement activities
and use of natural resources. Furthermore, this natural resources may be and
have affected economical constrains leading to transformation of the landscape
(such as timberline lowering due to high alpine pasture). From
palaeoclimatological work in the Western and Southern Alps it becomes clear
that the Holocene of the last 11550 years was characterized by at least nine
cold phases (with year mean temperature 1-2 °C lower as today) and intermittent
warm phases up to ca. 1 °C warmer than today. Probably such climatic
fluctuations as well as human impact as recorded for the last 10000 years in
the Silvretta Massif by archaeologically known remnants currently under
excavation (e.g. settlement structures, abris and livestock enclosures) had an
high impact on the alpine flora and vegetation (as well as its diversity), and
on prehistorical yield of cultural plants in the adjacent valleys. However, high-resolution
reconstructions on micro-palaeoclimatology and anthropogenic change using
pollen and spores, non-pollen palynomorphs as well as plant macrofossil remains
do not exist for the Silvretta Massif intermittently lying between the Central
and Eastern Alps up to now and are aimed
within the CCA-project using well dated palaeoecological bog/lake sediment archives.
