Animals poisoned by herders for years were actually helping livestock
1+ day, 10+ hour ago (967+ words) Plateau pikas labeled as pests can actually help livestock gain more weight by keeping poisonous weeds from taking over valuable grazing plants. High on the grasslands of the Qinghai-Tibetan Plateau in western China, herders have spent decades trying to wipe…...
Climate change is turning northern farmlands into nitrogen pollution hotspots
4+ week, 2+ day ago (720+ words) Climate change could unleash nitrogen stored in dry soil, turning northern farmlands into pollution hotspots as rainfall and storms intensify. For as long as researchers have tracked it, China’s worst cropland nitrogen pollution has occurred in the humid south. Heavy…...
Climate pledges could put the world's food supply under pressure
1+ mon, 5+ day ago (820+ words) Here’s an uncomfortable possibility nobody planned for: aiming to save the planet from overheating might, in the process, quietly starve it. A new analysis warns that climate commitments leaning hard on planting forests and other land-based carbon removal could shrink…...
Millions face growing food insecurity as climate change hits small island nations
1+ mon, 3+ week ago (1130+ words) Climate change pushed an additional 2.7 million people in the world’s small island nations into food insecurity in a single year, a new study has found. Across 26 Small Island Developing States, more frequent heatwaves and droughts took a growing toll in…...
Most toxic alga ever recorded caused Australia's mass marine die-off
2+ mon, 1+ day ago (957+ words) Millions of marine animals died when a massive harmful algal bloom spread along South Australia’s coastline, leaving scientists scrambling to identify the culprit. They found an unexpected answer. The bloom was driven by Karenia cristata, a little-known microscopic alga that…...
Ancient farming boosted plant diversity, but modern agriculture reversed it
2+ mon, 1+ week ago (955+ words) A new study has found that as farming spread across ancient Europe, plant diversity rose rather than fell. Researchers reading pollen buried in Swiss lake mud tracked the pattern over roughly 7,000 years, and found the land grew richer in species…...
A small change in cow feed may cut the methane footprint hidden in every glass of milk
2+ mon, 2+ week ago (876+ words) Pasture is the cheapest feed dairy farmers can provide, but by late summer it no longer meets a cow’s nutritional needs. As grass quality declines, cows in late lactation, still producing milk while carrying their next calf, begin running short…...
Swapping beef for salmon once a week helps the climate
2+ mon, 3+ week ago (851+ words) One simple food swap – replacing a beef steak with salmon once a week – could nearly double the carbon savings of simply continuing current dietary trends. New research has put numbers on what different levels of dietary change would mean for…...
Farmers helped double rice production despite decades of climate stress
2+ mon, 4+ week ago (700+ words) Global rice production came close to doubling between the 1960s and the 2010s – a remarkable achievement given that climate change was actively working against it the whole time. A new study found that human decisions deserve much of the credit. Expanded irrigation,…...
Europe is losing green land to concrete faster than scientists thought
3+ mon, 2+ day ago (852+ words) European official figures tracking how fast the continent loses natural land to construction are published every few years and feed into government targets. The working assumption was that those numbers, however imperfect, were at least roughly accurate. They were off…...
