I can't read this full paper because my university, quite rightly, is not willing to pay the extortionate fees charged by Nature Publishing Group, but the takeaways are clear from the abstract. 1/n

I'm generally skeptical of win-wins for agriculture and biodiversity, but this one seems legit: planting perennial crops on marginal land leads to more birds without reduced profit.

It's 2025 and there are still people out there trying to define a maximum sustainable human population - in this case 2 billion people.

In a contest in California, rice yields were on average ~40% higher than the average for the state. Does that mean that yields could go up by 40%? Probably not. Presumably only the most productive fields were entered into the contest, and growers could invest more than would otherwise be economical.

Rice production needs to increase to meet projected demand. Understanding a crop’s yield potential and the management practices and limitations to inc…

I'm trying to up my game when it comes to slide decks for academic presentations. Does anyone have a slide deck they're particularly pleased with that they would be willing to share? Or point me to someone else's deck if it's publicly available. Any other resources also appreciated.

I don't know what combination of causes led to this species' demise, but it was hunted on Malta back in the day and I once saw one in a hunter's private collection, an experience that sent shivers down my spine.

after combing through some 1,400 records, it looks like the slender-billed curlew is indeed extinct and the last known photo taken in 1995 was probably at the point it slipped beneath the waves 🦉🧪

Better nitrogen management in ag could reduce emissions of various polluting nitrogen compounds by up to one-third.

None of this is rocket science and could be implemented with the right policies and incentives.

One of the largest sources of greenhouse gas emissions from agriculture is in the form of nitrous oxide from soil processes. These emissions occur even with legumes, which receive little to no fertilizer. Soy actually accounts for 40% of emissions from corn-soy rotations in the US. 1/2

New study: we found that small reductions in pasture-based beef production in some areas, especially in temperate, humid regions like the Eastern US & Europe, could lead to large amounts of CO2 removal by regrowing native forests. Here's an explainer 🧵 www.nyu.edu/about/news-p...

If I'm reading this right, no-till increased total nitrate losses from agriculture and redirected the losses from runoff to leaching. Winter cover crops reduce runoff but don't affect leaching.
