Quantifying the greenhouse gas footprint of crop cultivation

A new study proposes a generic methodological framework to accurately quantify the greenhouse gas footprints of crop cultivation systems. The framework takes into account direct and indirect contributors, providing example values of emission factors and emphasizing the combination of measurements and model simulations.

The advent of 'green' cattle

A new method of carbon footprinting for pasture-based cattle production systems can identify 'green' cattle within a herd, reducing greenhouse gas emissions. The study found that existing methods underestimates the impacts of poorly performing animals, which produce disproportionately large amounts of methane.

Adding commercial soy in developing countries brings unique challenges

Growing commercial soybean in developing countries requires changes to traditional agricultural practices, including weed and pest control, soil correction, and access to certified seed supply chains. This shift can lead to poverty reduction, nutrition improvement, and rural economic development, but also a tradeoff of higher chemical ...

Unbalanced wind farm planning exacerbates fluctuations

A new study reveals that Europe's wind energy capacity is concentrated in the North Sea region, leading to extreme fluctuations. Cooperating countries can balance capacity across the continent to minimize these fluctuations. However, expanding solar energy capacity tenfold would be required to compensate for longer-term fluctuations.

Making cows more environmentally friendly

A study by Royal Botanic Gardens Kew suggests that plants growing in warmer conditions are tougher and have lower nutritional value to grazing livestock, potentially inhibiting milk and meat yields and raising the amount of methane released. This vicious cycle threatens to further exacerbate climate change.

A better way to farm algae

A new technology for energy-efficient cultivation and harvesting of microalgae has been developed by Bendy Estime, improving growth rates up to 10 times larger than traditional methods. The Tris-Acetate-Phosphate-Pluronic medium allows algae to grow in clusters without sticking to container walls, eliminating the need for constant stir...

Climate model predictions are telling a consistent story

A study by Aarhus University scientists uses three independent climate modeling methods to demonstrate that wheat yield will decline with global temperature increases. The models project a 5.7% decline in global wheat production for each 1°C temperature rise, with warmer regions expected to suffer the most.

Widespread evidence of prehistoric dairying discovered along the Mediterranean coast

Researchers have uncovered widespread evidence of prehistoric milk production in southern Europe, dating back to the onset of agriculture around 9,000 years ago. The study found varying intensities of dairying and non-dairying activities across the northern Mediterranean region, with the slaughter profiles of domesticated animals mirro...

Early evidence of dairying discovered

Scientists have discovered evidence of prehistoric milk production in southern Europe dating back to the onset of agriculture around 9,000 years ago. The study suggests that dairying played a crucial role in sustaining early farmers and spreading farming across the western Mediterranean region.

Refrigerator us warm?

A new discovery at RUDN University allows for substantially increased production of high-quality planting material using artificial winter in the fridge. This method uses micro cloning to grow plants from small buds, with potential benefits including increased plant height, reduced virus attacks, and improved plant health.

Can palm oil be sustainable?

A new study identifies nearly 1.37 billion hectares of land globally suitable for oil palm cultivation, while avoiding protected forests and high-biodiversity areas. The resulting map includes 19.3 million hectares of land that could be available for future production, slightly more than the current extent of palm oil production.

Droughts hit cereal crops harder since 1980s

A new study led by McGill University and the University of British Columbia found that droughts have a significant impact on cereal crop production, particularly in developed nations. The research analyzed data from 177 countries and found that global production lost to extreme weather events averaged around 9-10%.
