Linking sustainable food with food waste in policy; a NERC innovation placement in WRAP.

在全球范围内，粮食生产占水资源使用的70%，土地使用的90%和温室气体排放的30%。按照目前的发展轨迹，粮食产量需要在未来35年内增长60-100%，这对未来粮食系统的可持续性甚至可行性提出了问题。与此同时，目前的消费模式造成了巨大的环境和社会问题。通过消除食物浪费，可以节省多达三分之一的用于生产食物的资源[1]。然而，许多食物也因过度消费而“损失”。在英国消费的食物数量和类型都不符合我们的身体需要，或者我们的环境可以最好和最有效地提供。许多科学报告表明，我们不能“修复”气候，除非我们也“修复”“西方”饮食模式。食品过度消费的外部性由社会承担[3]（例如，通过公共卫生成本，导致气候变化的直接和间接排放，砍伐森林以清理农业用地），因此，出于社会，环境和经济原因，需要改变政策以提高供应链的效率，减少浪费并改变食物选择。废物与资源行动计划（WRAP）是英国防止食物浪费的领导机构，一直是全球重要的参与者，与政府、企业和社区合作，实现积极的变革，包括全国性的运动和全行业的承诺。这一创新安排为WRAP提供了扩大其能力领域的机会，将可持续粮食生产和消费的各个方面包括在内，具体而言，通过健康的可持续饮食及其与减少食物浪费的相互作用来改变食物选择。这代表了WRAP议程的变化，它补充了减少食物浪费的核心计划，并将WRAP转变为可持续食品政策的可信和全球公认的声音。对于这个创新职位，知识交流研究员Christian Reynolds博士将综合NERC和UKRI资助的研究项目的结果，WRAP及其行业合作伙伴可以获得的新产出和政策建议。Reynolds博士是一位食物浪费和可持续饮食专家，熟悉谢菲尔德大学的学术研究、数据和技能、N8农业食品项目和更广泛的英国研究界。雷诺兹博士位于谢菲尔德可持续食品未来大学，该大学通过对农业食品系统的综合跨学科研究来解决全球粮食安全问题。N8农业食品项目是一个跨学科的研究计划，将世界领先的作物和牲畜研究与8所研究密集型大学（达勒姆、兰开斯特、利兹、利物浦、曼彻斯特、纽卡斯尔、谢菲尔德和约克）的广泛社会科学专业知识相结合。N8 Agrifood致力于在面临环境和社会经济挑战时确保国家和全球农业食品供应链。N8最近通过IknowFood计划（约克）获得了NERC和BBSRC的资助。创新安置将通过N8将NERC的研究能力与WRAP及其行业合作伙伴联系起来，并为WRAP当前的运营和政策制定增加价值。雷诺兹博士将协助的关键领域包括：1）部分和包装-它们对饮食和食物浪费的影响2）解开人们吃什么和他们浪费什么之间的关系3）根据学术研究，证据和数据制定政策建议和行业协议。这包括与英国和全球合作伙伴的合作[1]机械工程师学会，“全球食品-不浪费，不匮乏”伦敦，2013年[2]T。Garnett，“Plating up solutions”，Science（80-.）.，第353卷，第6305期，2016年[3]NERC研究：在城市地区生产和消费自己的食物的健康风险和益处（谢菲尔德），ICnowFood（约克

Globally, producing food accounts for 70% of water use, 90% of land use and 30% of greenhouse gas emissions. On the current trajectory, food production will need to increase by 60-100% in the next 35 years, posing questions for the sustainability or even viability of such a future food system. Concurrently, present consumption patterns cause large environmental and societal issues. Up to a third of the resources used to produce food could be saved by eliminating food waste[1]. However, much food is also 'lost' to over-consumption. Both the quantity and the types of food consumed in the UK are not aligned with what our bodies need, or what our environment can best and most efficiently provide. Numerous scientific reports have shown that we cannot 'fix' the climate, unless we also 'fix' the 'western' eating patterns[2]. The externalities of the over-consumption of food products are borne by society [3](e.g. through public health costs, direct and indirect emissions contributing to climate change, deforestation to clear land for agriculture), and as such for social, environmental and economic reasons, policies changes are required to increase the efficiency of supply chains, reduce waste and shift food choices. The Waste and Resources Action Programme (WRAP) is the UK's leading body on food waste prevention, and has been a key global actor, working with governments, businesses and communities to deliver positive change, including national campaigns and industry-wide commitments.This innovation placement offers WRAP the opportunity to broaden its areas of capacity to include aspects of sustainable food production and consumption, specifically, shifting food choices via healthy sustainable diets and their interaction with food waste reduction. This represents a change of agenda for WRAP, which compliments their core programme of food waste reduction, and shifts WRAP to being a trusted and globally recognised voice on sustainable food policy.For this innovation placement, Dr Christian Reynolds, a Knowledge Exchange Research Fellow, will synthesise the findings of NERC and UKRI funded research projects, into novel outputs and policy advice that are accessible to WRAP and its industry partners. Dr Reynolds is a food waste and sustainable diets specialist, and is familiar with the academic research, data and skills in the University of Sheffield, the N8 Agrifood project and the broader UK research community. Dr Reynolds is located within the University of Sheffield Sustainable Food Futures which tackles global food security through integrated interdisciplinary investigations of agrifood systems. N8 Agrifood project is an interdisciplinary research programme that combines world-leading crop and livestock research with extensive expertise in social sciences across 8 research intensive universities (Durham, Lancaster, Leeds, Liverpool, Manchester, Newcastle, Sheffield and York). The N8Agrifood is focused on ensuring national and global agrifood supply chains in the face of environmental and socioeconomic challenges. The N8 have recently been awarded NERC and BBSRC funding via the IknowFood programme (York).The innovation placement will connect the research capacity of NERC, via the N8 to WRAP and their industry partners, and add value to WRAPs current operations and policy development. Key areas where Dr Reynolds will assist include:1)Portions and packaging-their effects on diet and food waste2)Untangling the relationship between what people eat and what they waste3)Developing policy advice and industry agreements based on academic research, evidence and data.
