Intensifying #droughts threaten future #foodsecurity: Soybeans, #maize & spring #wheat are most drought-sensitive & prone to severe #yields losses, esp. in US, #Argentina, #Australia & China. GHG #emissions intensify the risk of #drought significantly... (1/2) doi.org/10.3390/atmos16010034 #USA #China

MDPIIntensified Drought Threatens Future Food Security in Major Food-Producing CountriesDrought is one of the most severe natural disasters globally, with its frequency and intensity escalating due to climate change, posing significant threats to agricultural production. This is particularly critical in major food-producing regions, where drought profoundly impacts crop yields. Such impacts can trigger food crises in affected regions and disrupt global food trade patterns, thereby posing substantial risks to global food security. Based on historical data, this study examines the yield response characteristics of key crops—maize, rice, soybean, spring wheat, and winter wheat—under drought conditions during their growth cycles, highlighting variations in drought sensitivity among major food-producing countries. The findings reveal that maize and soybean yield in China, the United States, and Brazil are among the most sensitive and severely affected by drought. Furthermore, using precipitation simulation data from CMIP6 climate models, the study evaluates drought trends and associated crop yield risks under different future emission scenarios. Results indicate that under high-emission scenarios, crops face heightened drought risks during their growth cycles, with China and the United States particularly vulnerable to yield reductions. Additionally, employing copula functions, the study analyzes the probability of simultaneous drought occurrences across multiple countries, shedding light on the evolving trends of multicountry drought events in major food-producing regions. These findings provide a scientific basis for assessing global food security risks and offer policy recommendations to address uncertainties in food supply under climate change.

"Europe is grappling with a severe #cereal production crisis, exacerbated by adverse weather conditions, high production costs with stable prices, low quality of output, and stiff competition from Ukraine.

“This season was particularly challenging due to a series of adverse weather events for harvest,” he added, highlighting how droughts in Southeastern Europe and excessive autumn rainfall have negatively impacted both quantity and quality of harvests."

Project DrawdownGreenwashing and denial won’t solve beef’s enormous climate problemsI’ll admit it: I like beef. Like many Americans, I was brought up to believe that beef was a central part of a traditional family meal. My mom made it. My kids ate it. Marketing campaigns told me it was healthy. Everywhere I went, I saw Americans eating lots of it. And for many years, I didn’t question these choices.

This year I planted a milpa-inspired bed with #squash #beans and #sorghum in place of #corn / #maize.

Everything grew great! The weird thing, however, was that the beans did not flower. At all. Until after the fall equinox when it was too late for them to mature pods. I planted Frijol Negro Santanero from Rancho Gordo that were grown in #Oaxaca. Turns out, much to my surprise, common beans can be day-length sensitive! I live too far north for this tropical variety.

End on view of a garden bed filled with tall sorghum plants, their tops developing fluffy bunches of seeds. The lower half or so of the plants are enrobed in a thick covering of bean vines. To the right, along the ground are the leaves and a fruit of a butternut squash plant.

So I set up an experiment to see what my #corn seeds (all the same variety given to me) would grow best in. I have the results, but I would like a prediction to compare it to. Please vote which plants you think will be the most vigorous. #Compost #Compostodon #Maize #ScienceMastodon #PlantScience I will reply once the poll closes with the actual results. Thanks!

Just three plant species, wheat, maize and rice, account for 60% of all food eaten globally. Crop science expert, Prof Tafadzwanashe Mabhaudhi, argues that many of Africa’s 30,000 edible plants must be revived.
