The demand for dairy produce is growing alongside concerns about the impact of intensive dairying on water quality owing to nutrient loss. We found that nitrogen losses were greatest from all-grazed systems, but could be lowered by incorporating some housing.
Understanding the relationship between the production of farmed Atlantic salmon and the use of marine resources is imperative for planning the future growth of this industry and the sustainable management of these marine resources. This study demonstrates that the Atlantic salmon aquaculture industry can grow without the input of additional marine resources.
A realist review of 20 voluntary actions by the food and beverage industry in low- and middle-income countries analyses the implications of these actions for public health and policy. This realist review reveals that voluntary actions often aim to protect industry interests rather than improve public health.
Tillage on slopes thins the soil and reduces crop yields. Increased yields in regions where soil is deposited partially compensate for this reduction in crop yields at regional scales. However, continued increases in tillage intensity and climate-change-induced increases in dry spells may lead to reduced crop yields.
The digital twin technology uses real-time sensor data and in silico models to predict food quality and marketability metrics for every single refrigerated shipment. With this approach, we can identify the optimal shipment temperature window for maintaining citrus fruit quality, killing fruit fly larvae and avoiding chilling injury.
Modelling the quantitative effects of sustainable degrowth and efficiency proposals on greenhouse gas (GHG) emissions, material output and economic activity shows that a combination of both can lead to a sustainable transformation of the food system.
A farmer’s decision whether to use fertilizer is complicated in rainfed areas because the resulting yield gains vary greatly depending on rainfall, temperatures, soil conditions and many other factors. Farmers on about 25% of sub-Saharan Africa’s rainfed maize-growing land face an unacceptably high likelihood that this productivity-enhancing input will not pay off.
