Variety is the source of life: Agrobiodiversity benefits, challenges, and needs
SWISS ACADEMIES FACTSHEETS, VOL. 15. NO. 1, 2020
For millennia, humankind’s food security and resilience were ensured by thousands of cultivated plant species, dozens of domesticated animal species, and the wider biodiversity from which they derive. But with the expansion of industrial agriculture and globalized standardized food systems, this long-running agricultural biodiversity has fallen steeply. Today, just three plant species account for half of all plant-based food calories, and only four animal species account for the vast majority of meat supplies. Looking ahead, restoring agrobiodiversity – the richness of what we cultivate, breed, consume, and conserve in the wild – is crucial to ensure resilient food systems against the backdrop of climate change.
In particular, we must safeguard the livelihoods of the “guardians of agrobiodiversity”: approximately 500 million small farms across the world – particularly those in the global South. This factsheet outlines causes and consequences of agrobiodiversity loss, areas of promise, and options for policy and research.

Ethical guidelines for animal experiments
The Swiss Animal Welfare Act permits the use of animals for certain scientific purposes; at the same time, however, it requires that the dignity of animals be respected and their welfare protected. For researchers, reconciling these various societal interests can be challenging. The ethical guidelines for animal experiments (2025) are designed to clarify the margin of discretion left by the legislation and to encourage researchers to reflect on the handling of animals in their experiments. The decisive factors for updating the previous version from 2005 were new scientific knowledge and research methods on the one hand, as well as changes in the legal framework on the other.

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.
