全球人口到2050年将达到90亿,我们怎样提高农业产量来保障粮食供给呢?

每天有将近10亿人食不果腹,其后果极其严重。饥饿可能是致命的——营养不良导致饥饿人口极易感染疾病。饥饿还造成各国的国内生产总值每年损失4500亿美元。

约翰·克里国务卿指出,确保人民有足够的粮食“必须被纳入全球议程的最前列”。他说:“做不到这一点我们就无法完成其他工作。”

全球人口到2050年预期达到90亿人,专家指出粮食产量必须翻番才能满足需求。特别是在气候变化加剧并威胁更多的农田和牲畜,从而使这项任务更加艰巨的时候,我们怎样才能提高粮食产量呢?

关键在于对农业生产进行简便、明智的投入。今天,我们掌握着科学、创新和技术,能以可持续方式为这个人口不断增长的地球提供粮食。

妇女也必须参与解决问题。她们作为农牧民、创业者和社区领袖发挥着关键性作用,但她们获得教育和信贷的机会远远不及男性。如果女性能与男性一样获得同等的资源,她们便能提高农业产量,最高可达30%

美国一直在发挥主导作用,发掘农业生产的潜力,以减轻饥饿和营养不良。2010年,欧巴马总统发起了保障未来粮食供给( Feed the Future)行动计划,力争在19个需求最迫切的国家改善农业发展和粮食安全。

保障未来粮食供给行动计划帮助小农户,特别是妇女,获取提高作物产量所需的工具和技术。该计划同公司企业、高等院校和非政府组织共同努力,正在全世界最贫困的一些社区打破饥饿循环。

  • 在孟加拉国,农民利用经过改进的肥料、稻米品种及管理方式,提高了稻米产量,最高可达20%。
  • 在塞内加尔,抗旱种子及更有效的管理技巧的引入帮助农民将玉米产量提高了一倍。
  • 在洪都拉斯,价值高的作物的销售额提高了125%,帮助4300多个家庭达到贫困线以上。

2015年米兰世界博览会美国馆(USA Pavilion at Expo Milano 2015)将具体介绍粮食及农业创新如何帮助为全球人口提供粮食。


How will we feed 9 billion people in 2050?

Almost a billion people go hungry every day, and the consequences are enormous. Hunger can be deadly — malnutrition leaves the hungry especially vulnerable to diseases. Hunger also costs countries $450 billion a year in lost gross domestic product.

Ensuring that people have enough food to eat “has to be near the top of the global agenda,” Secretary of State John Kerry says. “There’s not much else we can get done without it.”

With the world population expected to reach 9 billion by 2050, experts say food production will need to double in order to meet demand. That’s a daunting task, made even harder as climate change accelerates and threatens more cropland and livestock. What can we do?

The answer lies in simple, smart investments in agricultural production. Today, we have the science, innovation and technology to sustainably feed a growing planet.

Women must also be part of the solution. They play crucial roles as farmers, entrepreneurs and community leaders, but have far less access to education and credit than men. If women had the same resources as men, they could boost farm yields by up to 30 percent.

The United States has been a leader in unlocking the potential of agriculture to reduce hunger and malnutrition. In 2010, President Obama launched the Feed the Future initiative to improve agricultural development and food security in 19 of the neediest countries.

Feed the Future helps small farmers, particularly women, access the tools and technologies they need to increase crop yields. Together with businesses, universities and nongovernmental organizations, the program is breaking the cycle of hunger in some of the world’s poorest communities.

  • In Bangladesh, the use of improved fertilizer, rice varieties and management practices has helped farmers increase rice yields by up to 20 percent.
  • Farmers in Senegal were able to double their maize yields with the introduction of drought-tolerant seeds and better management techniques.
  • More than 4,300 Honduran families are now above the poverty line in part due to a 125 percent rise in high-value crop sales.

World Food Day is October 16. Learn more about how innovations in food and agriculture can help feed the world at the USA Pavilion at Expo Milano 2015.
