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.

到2050年，我们需要在自然资源减少的情况下养活超过90亿的人口，同时还要确保人类和地球的健康。在此，我们将未来的全球粮食需求与农业和食品科学在生产和稳定食品以满足全球粮食需求中的作用联系起来。我们着重指出面对气候变化和正在塑造未来世界的全球大趋势，粮食和农业系统面临的挑战。我们将讨论减少粮食损失和浪费，回收目前浪费的农产品的机会，以使其成为食品工业的新原料。面对全球和行业大趋势，我们基于系统的观点将粮食安全与农业生产力，食品安全，健康和营养，加工和供应链效率联系起来。
