Gene drives: benefits, risks, and possible applications

Gene drives are genetic elements that skew the pattern of inheritance of a given characteristic in sexually reproduc- ing organisms. They can be used to spread a characteristic that can alter or even reduce the numbers of individuals in wild populations of a certain species.

How can science help to guide the European Union’s green recovery after COVID-19?

The design of efforts by the European Union (EU) and its Member States to recover from COVID-19 will determine the quality of people’s lives for decades to come. Related to the EU’s plans for a green recovery, European Academies urge policymakers to recognise the critical role of science and to step up efforts in three key areas: energy, ecosystem and health.

Cratschla 1/20

Schwerpunkt dieser Ausgabe: Biodiversität. Im Schwerpunktbeitrag zum Thema Nahrungsnetze zeigen Anita C. Risch und Martin Schütz von der WSL sowie Pia Anderwald vom SNP, wie sich Pflanzen und Pflanzenfresser beeinflussen und wie sich dies auf die wirbellosen Tiere und den Boden auswirkt. In der Reportage entführt uns der Ameisenforscher Christian Bernasconi in die abenteuerliche Welt der Waldameisen.

Rapport annuel 2019 de la SCNAT

La crise de la biodiversité et le changement climatique ont beacoup en commun. Opposer les problèmes n’a guère de sens d’un point de vue scientifique. Mais les scientifiques doivent s’impliquer encore plus dans le processus de recherche de solutions en dialoguant avec les différents acteurs et actrices. Et es chercheur·e·s ont bien le droit d’exprimer leur inquiétude sur la base de conclusions scientifiques. Vous en apprendrez davantage à ce propos et aux autres activités de la SCNAT dans le nouveau Rapport annuel.
IPBES Global Assessment - Summary for Policymakers
  • 2019

The global assessment report on biodiversity and ecosystem services

A key objective of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) is to provide Governments, the private sector and civil society with scientifically credible and independent up-to-date assessments of available knowledge for better evidence-informed policy decisions and action at the local, national, regional and global levels.

Is Europe living within the limits of our planet?

This report assesses selected environmental footprints for Europe based on the concept of planetary boundaries. It explores various approaches for allocating global limits to the European level.

HOTSPOT 41/20 Arguments pour la sauvegarde de la biodiversité

La biodiversité est le résultat de processus évolutionnaires et elle caractérise la Terre par son unicité. La biodiversité n’est pas seulement la base de la vie, mais aussi une caractéristique inhérente à tous les écosystèmes. Les raisons de préserver cette biodiversité ne manquent pas: des populations génétiquement variées sont plus résistantes aux agents pathogènes; les prairies et les forêts riches en espèces peuvent stocker davantage de carbone; les paysages offrant une riche mosaïque d’habitats sont appréciés et rendent heureux.

Floodplains: a natural system to preserve and restore

The preservation and restoration of Europe’s largely degraded floodplains, must be better prioritised according to a European Environment Agency (EEA) report. The report says floodplains have a key role to play in improving biodiversity, water, and climate change mitigation and adaptation.
Variety is the source of life: Agrobiodiversity benefits, challenges, and needs
  • 2020

Variety is the source of life

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.
