    Earthworms contribute to plant growth. Here, Fonte et al. conduct a global meta-analysis and estimate that earthworms contribute to roughly 6.5% of global grain (maize, rice, wheat, barley) production and 2.3% of legume yields, equivalent to over 140 million metric tons annually.

    Population growth in China has increased the demand for food. Combining data-driven projections with field experiments, Luo et al. find that China can achieve self-sufficiency in maize production by 2030 implementation of optimal planting density and management without expanding cropping areas.

    Lablab is a legume native to Africa and cultivated throughout the tropics for food and forage; however, as an orphan crop, limited genomic resources hampers its genetic improvement. Here, an African-led South-North plant genome collaboration produces an improved genome assembly and population genomic resource to accelerate its breeding.

    This research quantifies the role of zero deforestation policies and potential leakages in Brazilian soybean production, the third major driver of deforestation globally. Here the authors provide the first estimates of net global avoided soy-driven deforestation from zero-deforestation import restrictions and find that such restrictions could help avoid ~40% of deforestation for soy cultivation in Brazil and ~2% of global deforestation.

    In chocolate production, a complicated tempering process is used to guide the crystallization of cocoa butter towards its most desirable polymorph, which gives the chocolate proper melting behavior, gloss, and snap—hallmarks of good quality chocolate. Here, the authors find that simply adding a specific phospholipid also directs crystallization towards this polymorph, producing chocolate with comparable microstructure and properties to tempered chocolate.

    Yellow fever virus (YFV) is an arbovirus affecting humans and non-human primates (NHPs) with seasonal transmission. Here Hamlet et al. model the monthly occurrence of YF in humans and NHPs across Brazil and show that seasonality of agriculture is an important predictor of seasonal YF transmission.

    China has pledged to achieve carbon neutrality in 2060. Here the authors find a promising option to abate 1.0 Gt CO2-eq yr−1 of carbon emissions at a marginal cost of $69 (t CO2-eq)−1 by retrofitting 222 GW of coal power plants to co-fire with biomass and upgrading to CCS operation across 2836 counties in China.

    Quantifying land use change is critical in tackling global challenges related to food, climate and biodiversity. Here the authors show that land use change has affected 32 % of the global land area in six decades (1960- 2019) by combining multiple open datasets to create the HIstoric Land Dynamics Assessment +.

    Agricultural sectors receive US$600 billion per year in government support, providing incentives for GHG emission-intensive production. Here, the authors show that removing this support will not reduce global GHG emissions by much; rather it will need to be radically redirected to contribute to climate change mitigation.

    Agricultural greenhouse gas emissions not only amplify the global climate crisis, but cause damage currently unaccounted for by food prices. Here the authors show the calculation of prices with internalized climate costs for food categories and production systems, revealing strong market distortions.

    Long-term dynamics of species’ range sizes play a crucial role in determining extinction risks. Here the authors simulate global vegetation cover and scenarios of anthropogenic land cover change to estimate habitat range sizes of thousands of mammal, bird, and amphibian species since 1700, and project trajectories up to 2100 under four emission scenarios and five socio-economic pathways.

    Fraudulent adulteration of edible oils is based on the fact that their characteristic fatty acid profile can be mimicked with mixtures of other oil types. Here, the authors use a deep learning method to uncover fatty acid patterns discriminative for ten different plant oil types and to discern composition of mixtures.

    Phosphorus is an essential nutrient critical for agriculture, but because it is non-renewable its future availability is threatened. Here the authors show that across the globe most nations have net losses of phosphorus, with soil erosion as the major route of loss in Europe, Africa and South America.

    Global largest agricultural ammonia (NH3) emissions in China have caused severe damage to both ecosystem and human health, yet no policy is formulated to reduce NH3 emissions. Here, the authors show that halving agricultural NH3 emissions with feasible technical mitigation options in China generates far more societal benefits than abatement costs.

    Studies on examining the climate impact on irrigated agriculture do not account for regional specific details. Here the authors studied both the direct and indirect impact of climate change on irrigated agriculture in the Yakima River Basin (YRB) and found that increasingly severe droughts and temperature driven reductions in growing season significantly reduces expected annual agricultural productivity.

    The greenhouse gas (GHG) mitigation potential of organic methods is poorly understood. Here, the authors assess the GHG impact of a 100% shift to organic food production in England and Wales and find that direct GHG emissions are reduced with organic farming, but when increased land use abroad to allow for production shortfalls is factored in, GHG emissions are elevated well-above the baseline.

Here the authors find that the adhesive holding the pollen together consists of two phases and the oily phase stabilizes the aqueous phase with respect to humidity changes.
