  • Local Plant Knowledge of Farmers' Families in the Napf-Region
    Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2009 Local plant knowledge of farmer’s families in Napf-region, Switzerland Poncet, Anna <javascript:contributorCitation( ’Poncet, Anna’ );>; Vogl, Christian R <javascript:contributorCitation( ’Vogl, Christian R’ );>; Weckerle, Caroline <javascript:contributorCitation( ’Weckerle, Caroline’ );> Abstract: This contribution presents preliminary results of an ongoing PhD project which aims to explore linkages between plant diversity and local plant knowledge in the Napf‐region in Switzerland. The central part of the Napf is a cultural landscape listed in the Federal Inventory of Landscapes and Natural Monuments of National Importance. Cultural Domain Analysis was used to get an overview of known and used plant species. In total 51 family members of twelve farmer families were asked to list indigenous plants, followed by semi‐structured interviews about the use of the species. Roughly 400 wild and cultivated plant species were listed. The most frequently mentioned were Taraxacum officinale agg. and Rumex obtusifolius L.. Mentioned use categories, with declining frequency, were food, medicine for humans and animals, decoration, handicraft, toys and customs. Statistical analysis on the influence of demographic factors like age, gender, education, cultural background and farming system on plant knowledge revealed that age is the most important factor to explain knowledge variation.

  • Quaternary Glaciation History of Northern Switzerland

The oldest Quaternary sediments of Switzerland are multiphase gravels intercalated by till and overbank deposits (‘Deckenschotter’). Important differences in the base level within the gravel deposits allows the distin- guishing of two complex units (‘Höhere Deckenschotter’, ‘Tiefere Deckenschotter’), separated by a period of substantial incision. Mammal remains place the older unit (‘Höhere Deckenschotter’) into zone MN 17 (2.6–1.8 Ma). Each of the complexes contains evidence for at least two, but probably up-to four, individual glaciations. In summary, up-to eight Early Pleistocene glaciations of the Swiss alpine foreland are proposed. The Early Pleistocene ‘Deckenschotter’ are separated from Middle Pleistocene deposition by a time of important erosion, likely related to tectonic movements and/or re-direction of the Alpine Rhine (Middle Pleistocene Reorganisation – MPR). The Middle-Late Pleistocene comprises four or five glaciations, named Möhlin, Habsburg, Hagenholz (uncertain, inadequately documented), Beringen, and Birrfeld after their key regions. The Möhlin Glaciation represents the most extensive glaciation of the Swiss alpine foreland while the Beringen Glaciation had a slightly lesser extent. The last glacial cycle (Birrfeld Glaciation) probably comprises three independent glacial advances dated to ca.

    Book Sur les traces de l'histoire de la Terre en Suisse WILDI, Walter Abstract La Suisse est un petit pays sur cette planète. Son histoire géologique est certainement plus ancienne, mais seules les quelque 300 derniers millions d'années sont suffisamment documentées pour raconter l'histoire que le pays partage avec la Terre entière. Ce livre décrit un voyage géologique à travers le temps et la Suisse, depuis les forêts tropicales, par les déserts de sel et la mer alpine tropicale au plissement alpin, au froid arctique et au changement climatique moderne. Auf den Spuren der Erdgeschichte in der Schweiz Die Schweiz ist ein kleiner Fleck auf diesem Planeten. Ihre Geschichte ist sicher älter, aber einzig die letzten etwa 300 Millionen Jahre sind hinreichend dokumentiert, um die Geschichte zu erzählen, welche das Land mit der ganzen Erde teilt. Dieses Buch beschreibt eine geologische Zeit- und Schweizerreise von tropischen Regenwäldern durch Salzwüsten und das warme Alpenmeer zur Alpenfaltung, zu arktischer Kälte und dem heutigen Klimawandel.

  • Chapter 8 : Forests and Decentralization in Switzerland : A
    2723 J&J Decentralization 8/4/05 9:55 am Page 152 Chapter 8 Forests and Decentralization in Switzerland: A Sampling Christian Küchli and Jürgen Blaser INTRODUCTION Switzerland has a long experience with decentralization and federalism. During the mid 19th century, large-scale clear-cutting of Alpine forests started in connection with high demand for timber from colonial countries and industrialization in Switzerland. The disastrous floods occurring simultaneously were linked to this clear-cutting. In response, the newly constituted Swiss Confederation passed a forestry law in 1876. Brief case studies of four sites in the Bernese Oberland illustrate the development of the interplay among government stakeholders at the national, cantonal and community levels, and between public and private forest owners. Stable relationships between public and private forest owners and the cantonal forest service emerge as a precondition for long-term forest management; but at the same time, changing conditions of the socio-economic context constantly make it essential to seek a new equilibrium among the three levels of government, as well as among the public and private forest owners and civil society. DECENTRALIZED FOREST MANAGEMENT AND CONSERVATION IN SWITZERLAND Switzerland comprises 26 cantons and about 3000 political communes. The country grew out of treaties between valleys, townships and other geographical units and was finally organized in its current form in 1848, when the constitution of the Swiss Confederation was enacted. Forest resources management and conservation have since been shared by the national (federal) level in Berne, the regional (cantonal) level and the local (commune and community) level, the latter being the main forest owners in Switzerland.
