Every year, 9 million people in the world succumb to hunger?that’s more than the deaths from AIDS, malaria and tuberculosis combined. But the solution to the global hunger crisis isn’t as simple as ramping up agricultural production.
For one, agriculture comes with a hefty carbon footprint, contributing 10 to 20 percent of the global greenhouse gases annually. Then, chemical overuse sows resistance in the pests and pathogens the substances intend to kill, making it harder for farmers to eradicate their associated diseases the next time around. Runoff from fertilizers may also pollute waterways.
It’s not enough to grow more food?humanity needs to grow more efficiently.
With an eye toward feeding the world’s growing population in a sustainable way, researchers from China and the U.S. may have found a clever solution?in the form of supersizing crops. Transplanting a human protein, known for promoting growth, into crops may engender larger, heavier and more bountiful plants, boosting agricultural yields by a whopping 50 percent, according to the new study in Nature Biotechnology. While the results are promising, experts say that more research needs to be done to test their agricultural mettle and ensure that the gains are replicable.
両国の小麦は黒海沿岸のイリチェスク、オデッサ港などからエジプト、モロッコ、イエメンなど中東・北アフリカ、サブサハラ向けに輸出される(図5)。ロシア産小麦と合わせると、世界の輸出量約2億tの内の約3割を占める。距離も近いために、輸入は海上運賃が安い時にスポット取引(hand to mouth)で行われている。これを中東・北アフリカの輸入側から見ると、同地域の2021〜22年の小麦輸入量は9,154万tで、世界小麦貿易量の45%を占める(表1,2)。
