Pollen allergy and the impact of a changing climate
While hay fever was almost unheard of in Switzerland 100 years ago, at present, around 20 percent of the Swiss population suffers from pollen allergy. Importantly, climate change is causing an earlier onset and increased intensity of the pollen season for many allergenic plants. Climate change also fosters the spread of highly allergenic invasive plants like ragweed. Furthermore, the combined exposure to air pollution and pollen may worsen allergic reactions through increased sensitivity and increased pollen allergenicity. Scientists of the Swiss Commission for Atmospheric Chemistry and Physics provide an overview of pollen, hay fever, and how climate change is affecting both.

Roles of Scientists in Sustainability Transformations: A Guide for Reflection and Workshop Facilitation
Scientists, scientific experts, and knowledge brokers often find themselves in situations where they need to play new roles in society or are criticised for positioning themselves at the interface between science and other societal fields of action. The present guide aims to stimulate reflections on, and discussions of, various different roles that scientists perform.

Changing wildfires: policy options for a fire-literate and fire-adapted Europe
There is an increased probability of extreme fires, due mainly to climate change (droughts and declining summer precipitation), rural depopulation, and land-use changes. To respond to this, a new European Academies report is calling for an urgent shift in wildfire policy – from reactive fire suppression to proactive, risk-based land management.
Already today, wildfires burn half a million hectares in the EU yearly on average, i.e. nearly twice the size of Luxembourg. While the Mediterranean remains the highest-risk region, the report warns that continental, alpine, and boreal regions must also prepare for a new era of fire. Instead of focussing on fire suppression and emergency response, the report advocates for an integrated EU framework for landscape fire-risk governance that prioritises prevention alongside these three elements: climate and land-use policies that focus on restoring carbon-rich peatlands and managing forests sustainably; integrate fire risk into biodiversity and tree-planting plans; and educate for a fire-resilient society.
The report under the auspices of the European Academies Science Advisory Council (EASAC) was drafted by scientists from across Europe. On behalf of the Swiss Academies of Arts and Sciences, Marco Conedera, forest engineer at the WSL Campus in Cadenazzo, contributed as a reviewer of a draft version.
Actor constellation - td-net toolbox profile 2 Pohl, C. 2020
This publication describes the actor constellation and is part of a series of tools and methods compiled in the td-net toolbox for co-producing knowledge. Actor constellation is a role-play for identifying the relevance of various involved actors for tackling a specific research question.
