预计到2050年,我们需要依靠逐渐枯竭的自然资源养活超过90亿人口,同时确保人类与地球的健康。因此,我们将未来全球的粮食需求与农业和食品科学在生产和稳定粮食以满足全球粮食需求方面的作用联系起来。重点强调了随着气候变化和正在塑造未来世界的全球大趋势的存在,农业和粮食系统面临着巨大的挑战。我们讨论了减少粮食损失和浪费的机会,以及如何回收目前被浪费的产品,将之转化为新的食品加工原料。这一视角系统化地将粮食保障与全球及行业大趋势下的农业生产力、食品安全、营养与健康、食物加工和供应链效率联系起来。我们呼吁通过跨学科的合作方式来研究粮食保障科学,并重点关注利用技术,同时考虑社会、市场和全球趋势,最终实现粮食和营养保障。

过去(1961-2000):人口增加了98%,粮食产量增加了146%,产量翻了1倍多,耕地利用面积增加了8%,农业水肥投入:氮肥增加了6倍,磷肥增加了2倍,灌溉用水增加了1倍。

现阶段(2010-2050):粮食需求量增加了71%(即额外需要127*1015千卡)

Abstract:

We need to feed an estimated population in excess of 9 billion by 2050 with diminishing natural resources, whilst ensuring the health of people and the planet. Herein we connect the future global food demand to the role of agricultural and food science in producing and stabilising foods to meet the global food demand. We highlight the challenges to food and agriculture systems in the face of climate change and global megatrends that are shaping the future world. We discuss the opportunities to reduce food loss and waste, and recover produce that is currently wasted to make this the new raw ingredient supply for the food industry. Our systems-based perspective links food security to agricultural productivity, food safety, health and nutrition, processing and supply chain efficiency in the face of global and industry megatrends. We call for a collaborative, transdisciplinary approach to the science of food security, with a focus on enabling technologies within a context of social, market and global trends to achieve food and nutritional security.
