Scientists sequence first ancient Irish human genomes

The study sequenced ancient Irish human genomes, providing evidence for massive migration from the Middle East and Pontic Steppe. These genetic influxes are believed to have introduced cultural changes, such as agriculture and bronze metalworking, which may have originated the western Celtic language.

The Danish nitrogen budget in a nutshell

A national nitrogen budget for Denmark shows significant reductions in nitrogen emissions from agriculture, but other sectors like energy production and transport remain major contributors. New initiatives, such as organic farming expansion and electric vehicles, aim to further reduce nitrogen losses.

Feed supplement greatly reduces dairy cow methane emissions

A new feed supplement has been shown to reduce dairy cow methane emissions by 30% without affecting feed intake, fiber digestibility, or milk production. This could have significant implications for global climate change, as animal agriculture is a major source of methane emissions.

Organic agriculture more profitable to farmers

A comprehensive study by Washington State University scientists David Crowder and John Reganold reveals organic agriculture has significant profit margins compared to conventional farming. Despite lower yields, organic agriculture offers greater environmental benefits and can expand its share in sustainable food production.

Spreading the seeds of big data

MSU researchers are using big data analytics to help farmers adapt to climate variability, reducing nitrous oxide emissions and algal blooms. The project aims to integrate crop models with satellite imagery and UAVs to promote water-, nutrient- and climate-smart technologies.

Did climate change help spark the Syrian war?

A new study suggests that a record drought in Syria (2006-2010) was likely stoked by ongoing manmade climate change, contributing to the 2011 Syrian uprising. The researchers found that the drought destroyed agriculture and drove dispossessed farmers to cities, exacerbating poverty and government mismanagement.

Humans erode soil 100 times faster than nature

Researchers found that rates of hillslope erosion before European settlement were about an inch every 2500 years, while during peak land disturbance in the late 1800s and early 1900s, rates spiked to an inch every 25 years. This indicates a 100-fold increase in soil loss due to human activities.

How will climate change transform agriculture?

A new study by IIASA researchers finds that climate change impacts on crop yields could lead to a 18% decline in global caloric production or a 3% increase by 2050. The researchers identified likely needed adaptations and transformations for global agricultural systems, highlighting the importance of irrigation and regional connections.

Ancient wisdom boosts sustainability of biotech cotton

A new study suggests that biotechnology and traditional agriculture can be compatible approaches toward sustainable agriculture. Combining computer modeling and field research, the international team found that diverse patchwork of crops in northern China slowed adaptation to genetically engineered cotton by a wide-ranging insect pest.
