2021 Policy Lab Workshop Update and Winning Team

2021 Policy Lab winning team

Read winning team member Miranda Burke’s blog on the Policy Lab here!

After a competitive application round, a group of early career researchers came together in April to discuss how to reduce food loss and waste to contribute to net zero emissions from the food system, each hoping to win the chance to publish a policy facing report as part of URKI discussions around the United Nations COP26 event later this year. Although the 2021 GFS Policy Lab was held remotely due to pandemic restrictions it was no less effective at generating collaborations, discussions, debate and solutions!

The 2021 Policy Lab workshop started with an introduction to the GFS programme by GFS director, Dr Riaz Bhunnoo. Riaz deftly set out the food security challenges and the ways the GFS programme aims to tackle them, including the training of early-career researchers via Policy Labs to provide the skillset to tackle such large interdisciplinary problems. The early career researchers attending this Policy Lab joined from across the whole of the UK and spanned the entire breadth of UKRI’s research remits; from psychology to biochemistry, to economics and animal welfare. This diversity was key in the success of this Policy Lab, generating radical and novel reforms to the food system to tackle the issue of food loss and waste.

Interactive quizzes and activities allowed the virtual Policy Lab to run successfully; one such game involved teams thinking of fantastical, unrealistic ideas to reduce food loss and waste. Proposals ranged from body-scanners at the entrance of shops that would tell you the precise food you needed for the day and not let you purchase any excess, to tables that physically prevented you from leaving if you hadn’t finished your meal. Participants then voted for the idea they liked the most- a pill that made all food you don’t particularly enjoy eating taste delicious! Teams then reformed, representing different food system stakeholders, and were tasked with identifying the positive and negatives of rolling out this pill in their sector. The team who came up with the pill, had to predict the consequences each stakeholder would identify. Ultimately, although the innovators thought of several pros and cons that the stakeholder groups hadn’t, they notably failed to anticipate a lot of the consequences. This whole thought experiment demonstrated the importance of cross-stakeholder collaboration, and the futile nature of food policies which don’t consider the whole food system and all of its participants. This key message on stakeholder collaboration and cross disciplinary approaches stayed front of mind throughout the workshop.

Professor John Ingram from the Environmental Change Institute, University of Oxford, launched the Policy Lab talks and provided a superb overview of the food system and the significant impact food loss and waste has on meeting climate agreements. From this sound basis, the attendees went on to hear from Martin Bowman, from FeedBack Global who passionately covered “Why the Climate Emergency Demands Food Waste Regulation” and demonstrated the urgency and importance of developing policy in this area. To enable this, Jack Miller from the Parliamentary Office of Science and Technology presented an invaluable toolkit and training session on how to write policy. Taken together, the first day was a powerful reminder of the aims of the Policy Lab and the potential impact it has in COP26 discussions.

On day two, attendees were taken on a journey through the food system, hearing from different stakeholder perspectives and exploring the range of causes of food loss and waste. The teams first explored the role of innovative technologies in reducing food loss and waste, including apps to distribute unsold food, packaging with precisely monitored atmospheres to prevent spoiling, and cameras in your fridges to report what food needed eating. Attendees heard from Professor Carol Wagstaff, from the University of Reading and lead in BBSRC’s Horticultural Quality and Food Loss Network,

Helen White, WRAP

who discussed how to maintain food quality and nutrients through food supply chains. Helen White from WRAP, provided staggering statistics on food waste in homes and the role of WRAP in generating this data which generated an excellent discussion. Our final speaker was Dr Christian Reynolds from the Centre for Food Policy at City University London who reviewed the effectiveness of current food loss and waste policies, and what the UK could learn from other countries. This was a brilliant and inspiring talk to end on, in part because Christian was returning to speak at the GFS Policy Lab after being an attendee at the same event a few years earlier!

The Policy Lab talks were interspersed with workshop sessions, allowing attendees to debate and discuss with each other and interact directly with the speakers.

Towards the end of the Policy Lab, attendees discussed and began to formulate ideas for their report pitches, branching off into teams. By the end of the 3 day workshop, attendees had developed some excellent and innovative proposals that directly tackled different causes of food loss and waste, and had been thoroughly researched and referenced. After going through several rounds of peer review we shortlisted the reports and announced the winning team, who are already working on their report- stay tuned!

Applications Open for 2021 Policy Lab: Reducing Food Loss and Waste to Contribute to Net Zero Emissions from the Food System

The Global Food Security programme (GFS) invites applications from post-doctoral researchers at an early stage of their careers to take part in the 2021 Policy Lab on reducing food loss and waste. This is particularly focused on reducing emissions from the food system and contributing to net zero goals.

We seek applicants interested in using an interdisciplinary and systems approach to propose evidence-based policy recommendations that will help reduce food loss and waste and contribute to achieving net zero emissions from the food system.  The call is open to post-doctoral researchers in any discipline with links to the food system (for example biological, social, environmental, physical and economic). This could include areas such as, but not limited to, marketing, agriculture, food and packaging manufacturing, crop sciences, sustainability, ecology, microbiology, genomics, economics, behavioural sciences or nutrition.

Introduction to the GFS Policy Lab:

GFS Policy Labs offer the opportunity for early career researchers to learn about evidence-based policy, collaborative working and solving interdisciplinary challenges affecting our food system. Applicants from any disciplines are invited to a series of  online workshops across the 20-22nd April where they will learn how research can inform policy and scope the issue of reducing food loss and waste throughout the food system, with the opportunity to interact with stakeholders. At this Policy Lab workshop, applicants will form interdisciplinary teams competing for the opportunity to publish a policy facing think piece, and up to £1,000 to support this. This 10-page synthesis report will cover the background to a specific problem and subsequent recommendations for policy, practice and research around the topic of reducing food loss and waste and the environmental benefits of doing so.

Previous winning teams have presented their findings directly to governmental departments and programme partners, including the Department for Environment, Food and Rural Affairs (Defra), Department of Health and Social Care (DHSC), Department of International Trade (DIT), Department for Business, Energy and Industrial Strategy (BEIS) and partners in UKRI. This year we have submitted a bid for the winning team to release their report on an international platform at the United Nations COP26 conference on climate change in Glasgow, November 2021 (1) and are awaiting to hear the outcome.


Globally 30-50% of our food produced for consumption is lost or wasted (2). Food loss and waste refers to both the reduction of food quantity and/or quality as it passes through the food chain. Food loss generally refers to food lost after harvesting whilst it passes through the supply chain, but before it ever reaches the consumer, for example, food which is damaged during transport and processing, or is improperly stored. Conversely, food waste generally occurs towards the end of the supply chain and refers to food that was fit for consumption, but for some reason is discarded due to consumer or retailer action. Food loss can include produce wasted due to an unappetising appearance or cosmetic defects, or food which is left too long and spoils or expires. The proportion of food waste and food loss varies geographically, based on environmental and social contexts; for example in the UK food loss is relatively low due to technical capabilities in storage and post-harvest processing, whereas higher levels of food waste are driven by uncoordinated supply chains and consumer behaviour (3).

Food loss and waste are global issues which affect the entire food system. There are significant costs incurred by food loss and waste both globally and locally in the UK, including:

  • Climate and environmental impacts: If food loss and waste was a country, it would represent the third largest greenhouse gas contributor globally (4). Approximately 6% of all global greenhouse gasses arise from producing food that is lost or wasted, exceeding that of the aviation industry three times over (5). The UN Food and Agricultural Organisation has calculated the global environmental cost of food loss and waste to be over $700 billion per year (6); these costs arise from unnecessary resources, water, energy, fertiliser, transport and agricultural land used in the production of the wasted food. Our biodiversity and natural landscapes are also effected, with an equivalent area of land larger than Wales required to produce the food that is thrown away in the UK (6). Additionally, the wasted food itself also generates methane as it decomposes in landfill, a far more potent greenhouse gas than carbon dioxide; eliminating food loss and waste from UK landfill alone would equate to removing 20% of the cars from UK roads (7).
  • Social and ethical implications: Hunger is a condition of life for a tenth of the population (8), in part because of food loss and waste. Reducing food loss and waste is ever more important when the growing global population (9) and changing consumption patterns of individual countries are considered (10). In the UK up to 10% of the population is food insecure, with 2% using food banks (11) whilst 9.6 million tonnes of food is lost and wasted per year (12). Moreover, food loss and waste represents the unnecessary loss of resources and efforts of human labour, undermining efforts to create a just and equitable food system.
  • Public health costs: Foods that are critical components of healthy diets are disproportionately affected by food loss and waste (13) due to the perishability of fresh, unprocessed produce, with approximately half of all fruit and vegetable produce lost or wasted, both in the UK (14) and globally (15). Similarly, food loss and waste can undermine nutrition by reducing food quality and quantity, and over 2 billion people globally lack vital micronutrients (16); food production produces more than sufficient vitamin A to meet global nutritional demands, however there is an 11% global deficiency (17) after food loss and waste is accounted for.
  • Economic costs: Food loss and waste represents a cost of over £19 billion per year to a range of stakeholders throughout the food system (18). UK food waste and surplus on farms alone accounts for 7.2% of our total primary production, with a market value of over £1.2 billion (19). At the other end of the food system, average UK households waste 8 meals a week, costing approximately £500 each year (20). The cost of food loss and waste throughout the food system increases the price of food, which has a disproportionate impact on low income individuals as a greater proportion of their income is spent on food (21).

Ultimately, reducing food loss and waste offers an opportunity to provide more food of a higher quality without the need for significantly more resources. Furthermore, unless food loss and waste is reduced, future efforts to achieve food security are significantly hindered.

2021 is the opportune time for a GFS Policy Lab on reducing food loss and waste: in November the UK is hosting the UN COP26 climate change conference (22), and this activity will showcase how reducing food loss and waste can contribute to net zero emissions from the food system; similarly, the UN Food Systems Summit (23) later this year will explore how the food system works towards the Sustainable development goals, including SDG 12.3 (24) which aims to reduce global food loss and waste by half before 2030; additionally, this year is the UN International Year of Fruits and Vegetables (25), which have one of the highest food wastage rates of any food products (26); lastly, the COVID-19 pandemic and Brexit have disrupted our food system and created the opportunity to build back in ways better than before. Tackling food loss and waste is essential in delivering food security, and transforming our food system to support healthy people and a healthy planet.

This Policy Lab will explore the scientific, technological, behavioural and policy changes which could help reduce food loss and waste throughout the food chain and the associated emissions. Identifying what these changes are will require interdisciplinary collaboration, as well as close interaction with food system stakeholders such as businesses and policy makers.
