近年来,摩洛哥伊尔福德地区受缺水和土壤退化困扰,农作物产量和质量持续下降。摩洛哥非洲中国合作与发展协会主席纳赛尔·布希巴联合中国企业,共同设立中非盐水农业示范农场,借鉴中国沙漠治理经验,引入中国的土壤改良剂和苦咸水淡化设备,大幅降低作物年用水量。“依托中国的太阳能技术,我们还设计研发了一套海水淡化和可持续灌溉系统。我们计划把这些基于中国创新技术的示范项目成果介绍给更多沙漠国家。”布希巴说,“中国愿意分享发展经验和创新技术,为更多全球南方国家带来减贫与发展的希望。”

“People were dying and we didn’t know why,” Cornman told me. “We didn’t understand the physics of why the planes were crashing.” The deadly gusts were thought to be blowing in from the ocean or from thunderstorms outside the airports. But the danger turned out to be right above them. In the late seventies, researchers at NCAR and the University of Chicago discovered that the crashes were caused by microbursts—sudden, violent downdrafts. In a microburst, a storm cloud dumps cool air and rain straight down, like water from a broken awning. The air spreads horizontally after it lands, so the pilot thinks he’s flying into a headwind at first. He lifts the plane’s nose slightly and decreases the engines’ thrust. Then the downdraft hits, followed by a vicious tailwind, sending the aircraft to the ground.
