The article summarizes key concepts and the scientific foundations regarding invasive non-native species and their management, with a focus on forestry. In particular, the three management phases 1) prevention, 2) early detection and containment, and 3) control and long-term management of established species are discussed. In Switzerland, over 100 non-native species are considered invasive by experts; many of them occur in forests. Given the complexity of the challenge, successful management in general needs to be adapted to specific contexts such as the forestry sector, and should involve directly affected decision-makers and experts. Dealing with invasive species is therefore a permanent task of the forestry sector as a whole, which can not be delegated to just one institution or administrative level (cantonal, national or international).

The 170th Annual Assembly of the Swiss Forestry Society took place at Andermatt in August 2013 with the theme "300 years of sustainable management". About one hundred forestry professionals took part in a seminar to debate the lessons of the last three centuries of sustainability for forest management. This article summarises the seminar results and draws conclusions for forest management in the future. The participants recognised that the greatest shortcomings were in the economic and social spheres. Measures were proposed in the area of knowledge of sustainable management, understanding of the forest ecosystem and in payment for forest services. The greatest challenge is considered to be responding to societal contradictions.

Drought: Research and Science-Policy Interfacing - Proceedings of the International Conference on Drought: Research and Science-Policy Interfacing | Year: 2015

Drought is a natural hazard that has hit Europe hard over the last decades. The DROUGHT-R&SPI project (2011-2015) advances on drought research and associated science-policy interfacing. This FP7 project works at various scales, ranging from local to the pan-EU level. In addition to the European level, the project works in six Case Studies, in Greece (local), Spain & Italy (river basin), Portugal, Switzerland, and The Netherlands (national). In the paper, the various drought science-policy interfacing approaches are described. An overall finding is that Science-Policy interfacing at detailed scales (i.e. specific to sector, context and territory) is easier than at pan-European scale. Another important conclusion is that successful science-policy interfaces develop over time, based on their specific (socio-economic, historic and institutional) circumstances and specific drought characteristics. As well, stakeholders appreciate to be engaged in science-policy activities, they express a benefit from being involved. The functioning of the science-policy interfaces has been observed to refine and improve in the case of prolonged or successive droughts. © 2015 Taylor & Francis Group, London, UK.

Historical or present oblique terrestrial photographs documenting natural disasters are abundant in archives, may be easily shot nowadays, and often depict very informative details. In most cases, however, they can hardly be georeferenced, what prevents a systematic and technical use of such material for analyzing and documenting the disaster-induced damage traces. The monoplotting software developed by the Swiss Federal Institute for Forest, Snow and Landscape Resarch (WSL) in Bellinzona has been conceived to meet these needs and allows georeferencing and orthorectifying ordinary individual photographs in order to produce georeferenced vector data by drawing them directly on the pictures and exchanging them with traditional GIS-Systems. In the present contribution we report on the results of selected applications of the monoplotting tool showing the suitability of the tool for the geographical processing of historical and present natural events, which are difficult to map in the field.
