Global Food Supply

Abstract Many animal feeds compete for resources with human food production. The current use of food system by-products and residues as feed could potentially be increased to reduce the competition. We gathered a harmonised global food system material flow database for crop, livestock and aquaculture production including the availability of food system by-products. This allowed us to analyse the potential to replace the food-competing feedstuff, here cereals, whole fish, vegetable oils and pulses, that currently account for 11% of total feed used globally, with available food system by-products. While considering the nutritional requirements in animal production, we found that the replacement could free food-grade feeds for human consumption and increase the current food supply in kcal by 11-17% (6-11% if the use of crop residues is not accounted for) and in terms of protein 11-15% (9-14%). Our results thus indicate that the increased feed use of by-products has considerable potential, particularly when used in combination with other measures, in the much needed transition towards more sustainable and circular food systems.

Global Food Supply

Pressure points in global food supply where resilience in supply chains can be limited or controlled are the equivalent of Critical Control Points in food safety systems. The approach of using critical control in supply chains can provide insights for nutritional improvement, sustainable food trade and food waste reduction. The pressure points determine the provision of a secure and sustainable food system where the outcomes of reducing their criticality are identified in the UN Sustainable Development Goals and other international programmes. These seek to reduce climate change impact and improve public health provision. While policy makers are rightly focussed on these targets, the data analysis methods required to rank and associate resource flow pressure points with commercial food supply chains and nutritional goals remain untested. Here, we show how methodologies can identify where opportunities to tackle future criticality exist, and where they are currently being overlooked for food categories that have the greatest consumer and dietary protein demand. The analysis provides insights that identify where latent restrictions in resilience can occur, so that the future risk of food insecurity is reduced.

Food supply chain management is becoming a critical management and public policy agenda. Climate change, growing demand, and shifting patterns of food production, delivery, and consumption have elicited a series of new challenges, such as food security, safety, and system resiliency. This chapter first introduces the typical players in a food supply chain and examines the global food system characterized by consolidation and industrialization. It then discusses some critical topics of the sustainable food supply chain that aim to address these challenges. These topics include traceability, transparency, certification and standards, and alternatives to industrialized food systems, including cooperatives, community-supported agriculture, and roles of small and medium-sized growers in regenerative agriculture. The chapter ends with a discussion of several important emerging logistics management topics, including last-mile delivery, new technology, and cold chain management.

Use Efficiency

Reducing nitrogen pollution across the food chain requires the use of clear and comprehensive indicators to track and manage losses. The challenge is to derive an easy-to-use robust nitrogen use efficiency (NUE) indicator for entire food systems to help support policy development, monitor progress and inform consumers. Based on a comparison of four approaches to NUE (life cycle analysis, nitrogen footprint, nitrogen budget, and environmental impact assessment), we propose an indicator for broader application at the national scale: The whole food chain (NUEFC), which is defined as the ratio of the protein (expressed as nitrogen) available for human consumption to the (newly fixed and imported) nitrogen input to the food system. The NUEFC was calculated for a set of European countries between 1980 and 2011. A large variation in NUEFC was observed within countries in Europe, ranging from 10% in Ireland to 40% in Italy in 2008. The NUEFC can be used to identify factors that influence it (e.g., the share of biological nitrogen fixation (BNF) in new nitrogen, the imported and exported products and the consumption), which can be used to propose potential improvements on the national scale.

Global Food

<p>Currently, the global food system is the single largest threat to people and planet. Food is the leading cause behind transgressing five of the nine planetary boundaries. It is a major source of carbon emissions, as well as the single largest contributor to global deforestation, overuse of fresh water and eutrophication of our aquatic ecosystems. And while agriculture has been a major engine of poverty reduction, agricultural activities are unable to deliver a decent livelihood for an estimated 80 percent of those living in extreme poverty. The projected increase in frequency and severity of climate extreme events is posing additional threats to the global food system.</p><p>A transformation towards a more inclusive, sustainable and health-promoting food system is urgently needed. This presentation will introduce the newly established Food Systems Economics Commission (FSEC) that provides detailed and robust evidence assessing the implications of the policy and investment decisions needed to foster a food system transformation. It integrates global modelling tools such as integrated assessment modelling and innovative applications of agent-based modelling with political economy considerations.  It investigates the hidden costs of our current food system, explores transitions pathways towards a new food and land use economy and suggests key policy instruments to foster the transformation towards a sustainable, inclusive, healthy and resilient food system.</p>
