有机构预测,到2050年,世界人口将从现在的65亿增长到90亿。为满足新增25亿人口的粮食需求,到2050年必须实现农业产出翻番。中国的粮食安全同样面临挑战。随着城市化的推进,中国将迎来三大高峰:人口高峰、城市化高峰和工业化高峰。三大高峰必然会带来耕地的非农化高峰,这给有限的耕地造成了巨大的压力。此外,频繁发生的极端天气事件和不断出现的自然灾害也将给粮食生产造成巨大压力。
Some organizations predict that by 2050 the world’s population will grow from the current 6.5 billion to 9 billion. To meet the food demand of an additional 2.5 billion people, it is necessary to double agricultural output by 2050. China’s food security is also facing challenges. With the advancing urbanization, China will usher in three major peaks: population peak, urbanization peak and industrialization peak. The three major peaks are bound to bring the non-agricultural peak of arable land, which has caused tremendous pressure on the limited arable land. In addition, the frequent occurrence of extreme weather events and emerging natural disasters will also put tremendous pressure on food production.
