It’s a truism of the diet industry that getting too little sleep can make fatty, sweet foods more tempting. Now, researchers think they know why: Sleep loss influences the same smell-processing neural pathway that smoking marijuana does. “This is an exceptional study,” says Christian Benedict, a neuroscientist at Uppsala University in Sweden who has worked on the effects of sleep loss on metabolism but was not involved with the new research. Sleep deprivation has long been known to make people crave higher calorie foods. To find out how that process works, Thorsten Kahnt, a neurologist at Northwestern University’s Feinberg School of Medicine in Chicago, Illinois, took inspiration from studies linking sleep deprivation in humans to an increase in certain molecules in the endocannabinoid system, a complex network of neurotransmitters and receptors that, among other things, is affected by marijuana. Studies in mice have shown this system influences how the brain processes smells. And smell is a powerful driver of appetite—as illustrated by any gas station cinnamon roll shop.
When conversations turn to the world’s climate and natural resources, they often also go to livestock production. That was the idea behind a session at the Global Agenda for Sustainable Livestock international meeting hosted by Kansas State University Sept. 9-13. The topic, “Climate and Natural Resource Use,” was one of several addressed as delegates from around the world convened to talk about opportunities and challenges for livestock producers in countries large and small, according to a Kansas State news release.
[行业报告] How the United States benefits from agricultural and food security investments in developing countries 进入全文
U.S. foreign agricultural assistance investments bring substantial economic, health, and security benefits to both developing countries and the United States. This report describes the food security investments of the U.S. Agency for International Development and how improving agriculture in developing countries brings positive returns to the United States and developing countries. The multiple benefits of foreign agricultural assistance include growth of agri-food systems of developing countries, and positive impacts on U.S. jobs and exports, technology spillovers that support U.S. agricultural production, health and nutrition of U.S. consumers, and global and U.S. security.
A former JPMorgan Chase & Co. analyst is using drones and satellites to boost Ethiopia’s agricultural exports and improve food security in a nation once synonymous with famine. Africa’s second most populous country, still struggles to feed itself. But now the government’s Agriculture Transformation Agency, headed by Khalid Bomba, is aiming for widespread commercial farming and food security in 20 years. It’s modeling itself on initiatives in South Korea and Taiwan. “The reason Ethiopia’s agricultural sector has not developed is because we have not leveraged technology,” said Bomba, 51, who spent a decade at JPMorgan on Wall Street and in London and later worked at the Bill & Melinda Gates Foundation developing and managing grants in the agriculture sector.
Outlining the first phase of a deal to end a trade war with China, U.S. President Donald Trump on Friday lauded his counterparts for agreeing to make purchases of $40 billion to $50 billion in U.S. agricultural goods. That would be double the $24 billion China spent on American farm goods in 2017. But Darin Friedrichs, senior Asia commodity analyst at brokerage INTL FCStone in Shanghai, threw cold water on the pledge. “I think it’s a meaningless big number, thrown out to get headlines, and won’t happen,” Friedrichs told Reuters.
On September 30 I attended a high-level policy roundtable. The question at hand: could (and should) soya bean production be increased in SA? Soya beans are critical for animal feed, and as incomes rise so does the demand for animal products. In fact, SA’s per capita consumption of poultry nearly doubled between 2001 and 2018, and the country has not been able to meet its demand for poultry feed. SA imports a half a million tons of soya bean oil cakes, 90% of which is imported from Argentina. As agribusiness executives interacted, one asked, “Why can’t we expand soya bean production in Mpumalanga?” Well, because the mining houses beat the agribusinesses in the competition for land — and the two industries can’t share the same ground because of the often irreversible environmental damage imposed by mining.
