NEW: Biofuels globally emit more than the fossil fuels they replace, our latest study shows. The first-of-a-kind study looks at global biofuels production today and the potential impacts of government biofuel targets. 🧵⤵️

Pissed off at that bonkers press conference confusing correlation and causation, and warning women off Tylenol? Yeah me too. But think of that next time a nutrition study makes headlines because, say, artificial sweeteners are associated with cognitive decline - to pick an example at random.

To grow food you need two things: some land and some of your time. Land and labor are two of agriculture’s primary inputs. To build a food system that works for people and the planet, humanity needs to achieve high productivity in both of them.

'Cows just replaced the methane from wild bison' Not even close. At their peak, wild ruminants incl. bison emitted ~15 Tg CH₄/yr Today’s 4+ billion farmed ruminants emit over 100 Tg CH₄/yr That’s nearly 7x more methane. essd.copernicus.org/articles/17/...

6. Then other people say, "we must rewild the world". Yes. But it's not going to happen without major dietary change. Eg we can't have grass-fed beef (the most land-hungry of all products) and rewilding. In fact, it drives a massive de-wilding. At this point, half the enthusiasts shuffle away.

Totally agree. There seems to be the idea that regen ag will do the trick. See our response to a BES report

Can Africa feed itself without further expansion of its agricultural land at a high C and biodiversity cost? => Would require *tripling* current annual yield increase to achieve cereal self-sufficiency. => Big differences between E & W Africa due to differences in nitrogen fertilization regime.

New research from my colleagues out today looking at the environmental and social impacts of food crop-based biofuels in the US, where we now use >30% of the corn supply and >40% of the soybean oil supply (on tens of millions of acres of prime cropland) to produce only ~6% of US transport fuel. 🧪

Fascinating study. For every 1000 bears in an area, there is an associated 4% increased likelihood of a bigfoot sighting. 🧪 zslpublications.onlinelibrary.wiley.com/doi/10.1111/...

Many "ultra-processed foods" are basically a trojan horse for getting more fat, sugar, and meat into diets in hyper-palatable form. But the political discourse around "ultra-processed food" and health is a trojan horse for mainstreaming disinfo and junk science and bad policy. Important distinction.

The average American diet requires about 2 acres of land per person per year (and that’s food grown and raised by people who are experts at growing and raising food)

🙄 when gardening gurus recommend applying a 4" layer of compost to vegetable garden beds. From my calculations, that's 260-320 tons/acre, way more than any farmer would apply. It's also over 2000 lb of nitrogen per acre. And then apply 1" annually after this, so another 500 lb of N...😬

Een kleine belasting op grasmaaien en gebruik van hogedrukreinigers zou een milieuvriendelijke manier zijn om een intergenerationele transfer van middelen te organiseren van te vroeg gepensioneerde boomers naar jongeren.

New paper in The Lancet Planetary Health where we show that Nitrogen enrichment not only substantially increases the pollen production of grasslands, but also the pollen allergenicity 🤧.

1. Yesterday I wrote a thread about the dire warnings from food professionals on the state of supply chains. Comfortable folk might find it impossible to imagine an end to the current abundance. But we'd better start imagining it fast. THIS thread is about solutions - false ones and sound ones.

Donald Trump has committed the most profound, harmful and unnecessary economic error in the modern era. Almost everything he said—on history, economics and the technicalities of trade—was utterly deluded econ.st/3YbbFjq

Highly recommend this worthwhile essay coauthored by @garrettbroad.bsky.social for this moment in environmental communication on "nature-based solutionism" (like grass-fed beef), including ai newrepublic.com/article/1933...

What mediates one's view on wolves? In short: it's likely your global attitude towards nature, but attitude towards hunting is a good enough proxy for that. A short 🧵 royalsocietypublishing.org/doi/full/10....

Oh come on.

Fragmented landscapes consistently have both lower α diversity and lower γ diversity. The whole body of literature on Allee effects makes some sense after all 🙂.

Resolves part of a 1/2 century old debate about whether habitat fragmentation reduces biodiversity, above and beyond habitat loss. We find that it does.

NEW: WRI report provides a "state of the science" & economic estimates of >25 agricultural methane mitigation solutions, including: 1. Increased livestock efficiency 2. Methane inhibitors 3.

Cover crop benefits are tied to cover crop biomass, but how much biomass do you need? Generally, more biomass is better, but thresholds differ for erosion control, soil benefits, and weed suppression. My latest... csanr.wsu.edu/cover-crop-b...

Ardennes. In less than 10 years literally every stream here has been colonized by beavers.

I always wonder why African scientists don’t speak out more often against radical agroecology ideas. Funding and Institutional Pressures? Power Dynamics in Global Science? Career Risks? Criticism can be perceived as support for industrial agriculture?

Opiniestuk vandaag van 40 Nederlandse wetenschappers vanuit diverse disciplines. Zoneren om aan biodiversiteitsbehoud te kunnen doen. De logica zelve. Maar hier in Vlaanderen zijn we daar als groenen tegen want zoneren zou de nakende Transformatieve Veranderingen wel eens in de weg kunnen staan.
