LivestockCheap milk test finds hidden mastitis on Kenyan dairy farms
A simple California mastitis test lets smallholders find udder infections in cows that look healthy, before milk yields fall and emissions per litre rise, ILRI researchers say.

AgrotechFermentation proteins cut emissions up to 98% against beef, GFI review finds
A Good Food Institute review of more than 30 life-cycle assessments finds biomass, precision and microalgae fermentation use far less land, water and emissions than meat, dairy and fish oil.
EnvironmentWould banning meat adverts change what Europeans eat? A climate psychologist weighs in
Amsterdam this year became the first capital to ban billboards for meat and fossil fuels; a climate psychologist says advertising shapes what feels normal, but a ban works best alongside other measures.
EnvironmentUNEP report says holding warming to 1.5C without overshoot is no longer possible
Global greenhouse gas emissions dipped slightly to 58.4 gigatonnes in 2025 only because land-use emissions fell; fossil fuel CO2 kept rising, and cuts of 18% by 2030 are now needed to limit the overshoot.
EnvironmentManitoba's first Net Zero Action Plan keeps $7.6 million for sustainable farming
The plan leans on fertilizer efficiency under the 4R framework and on existing farm programmes, but leaves open whether grain dryers qualify for efficiency support and how rollout will affect farmers.
EnvironmentClimate scientists warn of locked-in damage, drying land and costly overshoot of 1.5C
The 10 New Insights in Climate Science report, by more than 70 scientists, says past emissions have locked in more ocean warming and sea level rise, freshwater is vanishing across continents and food systems must change.
EnvironmentReduced tillage cuts emissions but mulching can raise them, Rothamsted review finds
An analysis of 422 studies found reduced and zero tillage the most reliable conservation practices for lowering greenhouse gases, while mulching and fertiliser strategies gave mixed results depending on climate and soil.
LivestockMore than 50 UK dairy farms trial 200 practical ways to cut emissions
The Defra-funded UK Dairy Carbon Network, led by AFBI, is testing nutrition, breeding, animal health and nutrient measures on farms across Great Britain and Northern Ireland, increasingly in combination.
EnvironmentUS irrigation avoids 363 times more greenhouse gas than it emits by sparing land, Colorado State study finds
A PNAS paper estimates that replacing irrigated yields with rain-fed cropland would release 6.86 gigatonnes of carbon, more than the whole US emitted in 2024; pump electrification would cut the direct emissions further.
