1/5 "Characterizing the Global Polycrisis: A Systematic Review of Recent Literature" - newly published in Annual Review of Env. & Resources (Rakowski & Schaan et al. 2025)! We harvested all papers on the global polycrisis and analysed a) what it is, b) its components, c) drivers, and d) solutions.

Interesting, I couldn't find any information about the respective vote in the @euparliament.bsky.social pages. Instead I found a rather opposite statement. Seems like stating A and voting B.

scientists, keep on signing to make our voices, including yours, heard. euobserver.com/242794/meps-...

Habitat loss is the biggest threat to the world’s wildlife. Nearly all habitat loss is driven by the expansion of agriculture: we chop down forests and convert wild grasslands into farmland to grow crops and raise livestock.

I'm informed that the number of signatories more than doubled since the call last week - but can we reach 3000? We also lack the voices of scientists form E, SE and S Europe. Please translate and forward the call to other languages to maximise reach ahead of Parliamentary discussions!

I'm shocked and saddened by this sudden loss. Sepp has been a central pillar in so much that has been happening recently, such as the successful fight for the EU's Nature Restoration Regulation.

Scientists: join an open letter on pesticides! Pesticide over-use has grave impacts on human health & the environment, yet the Commission proposed a deregulation (aka "Omnibus proposal on Food and Feed Safety"). Scientists call for a rigorous assessment prior to next steps: tinyurl.com/y5db7vsy

Food companies (and governments) are flying blind to the escalating climate threats to supply chains Shocks are increasingly likely to hit multiple regions at once, yet companies don’t have tools to assess the likelihood and impact of multiple supply shocks... www.reuters.com/sustainabili...

Indonesia is hindering access to government data on the state of its forests. The new restrictions come as the country witnesses a surge in deforestation.

📣 New campaign! What are #LandscapeFeatures and why do they matter? 🌾 Learn how powerful together are the hedgerows, ditches, stone walls & flower strips woven through farmland: better soil, cleaner water, more wildlife. 👇 Stay tuned for more! 🕵️ laferia-project.eu/news/benefit...

Happy to attend the kickoff meeting of the Knowledge Exchange Network on agro-ecosystems in Brussels, organized by @bioagora.eu Looking forward to exciting interactions!

Yes, facts and evidence are important. Science too. Yes, misinformation is a problem. But notably, biases in people's knowledge and opinions are not evolving out of the blue.

Butterflies are beautiful - and some more than others. The consequence is a bias in conservation efforts, but not necessarily in species' status. This bias is worth attention. Read more here: www.ufz.de/index.php?en...

Did you sign for keeping EU's nature laws alive? Let's reach 1 million signatures within the next 20 days! #HandsOffNature cc @birdlifeeurope.bsky.social @clienteartheur.bsky.social @eeb.org @wwf.eu

Newly published! www.sciencedirect.com/science/arti... We checked 28 indicators in CAP, NRR, Climate- & Soil Monitoring laws 4 mismatches btw policy, science & practice. Result: mismatch 4 ALL! Lead: Cian Blaix with @cleliasirami.bsky.social, @bdumontae.bsky.social, part of @agtransect.bsky.social

Great workshop during the @idiv-research.bsky.social congress last week, exploring alternative scenarios for restoring landscape features in intensive agricultural areas. More to come in @laferia-project.eu

When a poor CAP reform is on the table which defends the worst parts while cutting on what works, not much is left to save. Interestingly, I hear the wish to cancel the CAP mostly from AfD members, whereas most stakeholders we meet do prefer a CAP that works - for people, nature and healthy food.

Conservation works, we should do more of it

When people say ''I have lots of butterflies in my garden'', it's useful to get a quantitative estimate, in a standardized way. Example: At friends' garden (Alps near Granoble) I counted >50 individuals, 8 spp in a 15 minute count. Try the ButterflyCount app, you can now register sites too!

It's always a joy to meet good friends, both humans and non-humans, in nature. Here's one of my favourite, the Chalkhill Blue (Lysandra coridon, Silbergrüne Bläuling). Rare in many parts of Germany, but abundant in the Alps.

An investigation by @propublica.org and @drilledmedia.bsky.social has found that the same modelers who overestimated the potential of CCS repeatedly underestimated solar power - one of the energy technologies that would allow more oil to remain in the ground. projects.propublica.org/why-carbon-c...

The European Parliament will soon decide on its path for the CAP reform. Will they adopt a dangerous CAP proposal, or can they find a way to retain (or even expand and improve) what works? Watch our YouTube film and our plea for policymakers here: www.agroecology-transect.org/toolkit-reso...

I am honored to be one of the co-authors of @shawan-chowdhury.bsky.social's excellent paper, pulling together experts from so many countries to assess range shifts in butterflies across the globe. Great work, though worrying outcomes. More to come!

How do we scale up & scale out agroecology across Europe? Researchers, farmers, policymakers & practitioners tackled that question at @agtransect.bsky.social final event in Brussels Full recordings are available, including discussions on: • lessons from 11 Innovation Hubs 👉 doi.org/10.1007/s116...

Comprehensive article about the Flamingo Revolution in #Albania published by @earthislandjournal.bsky.social My contribution with focus on the impact of Vlora airport for the eventual alteration & destruction of #Vjosa #Narta ecosystem. @euronatur.bsky.social www.earthisland.org/journal/inde...

Unglaublich. Was Merz hier sagt, ist: 1) Die Wirtschaft ist wichtiger als das Leben von (Tausenden von) Menschen. 2) „Klimawandel“ gibt es nicht (offensichtlich, vermeidet er diesen Begriff) und die Klimawandel zu vermeiden kommt nicht in Frage. Gibt es hier einen Unterschied zwischen CDU und AfD?

No surprise. Governments that seek to maximise profits for the few, by all means, won't let anything stand on their way - be it nature, peoples' lives and wellbeing, or our future. Will the Albanian demonstrations expand? I'm looking forward to see, when the ''enough is enough'' moment comes.

Congratulations @zakisaati.bsky.social with this amazing paper! Some of those samples were ours from Belgium 🇧🇪

My talk at @scbeurope.bsky.social Only 10-15% of the EU's cattle herd is needed to graze every biodiversity-rich field there is. Most cattle never set hoof on pasture. They're fed grain, packed onto fertilized monocultures. The solution isn't more grazing. It's fewer animals, better raised.

My talk at @scbeurope.bsky.social - 2 Put every EU cow on pasture and you'd need more land, more emissions, more imported crops from elsewhere. Too many animals for the land we have. The fix isn't more grazing — it's less and better. #Agroecology #LivestockStrategy

At #ECCB2026 we speak with concern about #FoodSecurity due to heat, droughts, pollinators' loss, soil erosion, etc. Meanwhile at X, DG Agri happily anounces a promising year for... oilseed, dairy, pigmeat, poultry. @ec.europa.eu didn't u shout food security? Can't u take your own claims seriously?

Ugandan farmers have filed a lawsuit in London against TotalEnergies' EACOP project. They warn that the 1,443 km (897-mile) oil pipeline threatens 16 protected areas, including vital water sources for 40 million people, and note that more than 100,000 residents have already faced displacement.

Die EU plant ein Geschenk für Pestizidkonzerne: Giftige Pestizide könnten für immer zugelassen werden – ohne Sicherheitsprüfung. Ja, für immer. Ja, das passiert wirklich. Jetzt unterschreiben um den Plan aufzuhalten: action.wemove.eu/sign/2025-12...

When politicians and policies fail, i.e. when upscaling of solutions is impossible, outscaling is an excellent alternative - namely replicating what works, instead of awaiting someone else to help. Same might be needed for #agroecology and, more broadly, sustainable agrifood systems.

The Nature Restoration Regulation contains risky exceptions and exemptions. Volker Mauerhofer reminds that NRR should be legally interpreted in the narrow sense, i.e. complementary to the BD and HD. Court will likely have an important role. #ECCB2026

At #ECCB2026, Stefan Kreft presents a MARISCO-based 'strategic situation analysis for European forest biodivetsity'. Are we bending the curve? No Are we going to meet the 'biodiversity positive' target by 2030? No.

A study concluded that the uninhibited pumping of groundwater by farmers, cities and corporations around the world now accounts for 68% of the total loss of fresh water at the latitudes where most people live. (Published July 2025)

Looking at the EU Stress Test on the Birds and Habitats Directives: Merely 11% of respondents <30 year old. Is it poor familiarity with EU policies? Or law awareness of what the Commission means when they say "simplification"? Hey, youngsters, it's about the quality of YOUR future.

Gestern auf eine Wiese, habe ich das Schachbrett-Weibchen hier fotografiert, als ich bemerkt hatte, das am ende ihres Bauches hängt ein Ei. Zwei Sekunden später ist das Ei runtergefallen. Es ist vielleicht kaum zu glauben, aber manche Falter legen keine Eier ab - sie lassen sie einfach fallen...

The European Commission is placing the Birds & Habitats Directives under a "stress test" (while in parallel, losing grip on CAP and pesticides). The open consultation runs until 10.8.2026: ec.europa.eu/info/law/bet... Sor far 22 scientists (3.3%) contributed. Let's make science be heard too!
