The current food system is failing us.
Current food systems are not capable of reducing hunger and malnutrition. In fact, hunger in the world has been increasing, growing to nearly 821 million in 2017, from around 804 million in 2016. Also, overweight is sharply rising and has tripled since 1975, affecting 1.9 billion adults and 340 million children; every year 3.4 million people die from obesity. Hunger and overweight are strongly related to each other: children who receive insufficient infant and child nutrition are extremely vulnerable for overweight if exposed to energy-dense diets with high fat, sugar and salt content. While supplementation may offer some critical temporary solutions, the only structural solution to the problems of hunger and malnutrition is to improve the composition of diets.
The critical sense of urgency around food systems failures becomes visible in five related problems:
Changes in income and rapid urbanization lead to three directions of change in dietary patterns.

Deep food system reforms are required
To repair food system failures and to respond to the dietary transition, it is not sufficient to only ‘fix’ the problem at the level of particular stages of the food supply chain (such as improving input use, optimizing farm production, integrating processing, transport, and retail, or increasing household consumption and reducing waste disposal). While knowledge on technical solutions for how to close the yield gaps, how to reduce food losses, and how to improve the sustainability of production systems is widely available, their practical implementation is mainly hindered due to limited incentives or insufficient understanding of the drivers of food system change.
Fundamental elements for a more strategic food systems approach need to include attention for five mutually related FOCUS areas:
We need to develop a more integrated systems perspective where potential trade-offs and synergies between dimension of healthy, inclusive, and sustainable diets can be effectively addressed. Food system reforms are characterized by changes in systems dynamics that are generated by incentives at other stages than where the problems become apparent. This implies that food systems interventions are based on a deep understanding of the transactions and linkages between different stakeholders and the possibilities to influence their behaviour. Finding smart solutions outside the domain where the problem originally appeared will be particularly helpful to achieve more structural and permanent impact.
Incentives for business co-innovation
Changes in food systems cannot be effectively reached without active involvement of relevant stakeholders at different stages. Since it is crucially important to create suitable incentives for co-innovation, food systems change requires simultaneous interventions at different levels. Such co-innovation initiatives for healthier diets can be particularly useful to support systematic changes in food systems dynamics that jointly benefit different stakeholders and overcome structural dilemmas by identifying win-win solutions at aggregate systems levels.
Many interventions that focus on reducing food losses in the agro-food supply chain and prospects for integrating circular food systems usually meet severe constraints because most efforts must be made by producers at the beginning of the supply chain, while results are reaped at the end of the value chain, mostly by retailers (longer shelf life). Experiments in Nigeria with local producers and traders who deliver tomatoes to Lagos city over a distance of almost 1000 km indicate their willingness to use improved plastic crates for packaging tomatoes, thus substantially reducing post-harvest losses. But this practice only became institutionalized once traders showed joint commitments to engage in a return system, bringing the empty crates back to the producers, and therefore engaging in long-term delivery contracts with local farmers while transferring part of the extra revenues to them as well. This institutional arrangement thus complemented the technical innovation that enabled the upgrading of the whole food system.
In a similar vein, experiments with improved school feeding (menus prepared with fresh vegetables and dairy) and healthier meals in hospital and factory canteens in Vietnam and Bangladesh originally designed to deliver improved school results, better workplace attendance, or shorter hospitalization stays also can become particularly effective for generating spillovers to household eating practices and habits. The food system payoff of such focused investments becomes visible once similar ingredients and food preparation modes are also applied on a regular basis for preparing healthier meals in the home.
Changes in income composition and market engagement can also be instrumental for improving family diets. Whereas most efforts for promoting dietary diversify are based on homestead production (vegetables gardens, family poultry, and dairy), similar outcomes can also be reached by supporting households’ engagement in different input or output markets. Regular earnings from wage labour and from remittances lead to different patterns of income flows that are also used to purchase different types of food. Moreover, buying food through home delivery systems offers opportunities to increase convenience and optimize portion size of fresh food. Improving consumption patterns can thus be supported by modifying labour use and market outlet choice.

Public policies for ending malnutrition
Many of the before-mentioned innovations need to be supported by public policies that shape a conducive environment for healthier and sustainable food systems. Individual food choices are – to a great extent – influenced by the complex and layered food environment that includes multiple linkages with formal and informal traders, retailers, and marketing agents as well as vertical cooperation and contractual systems between food supply chain stakeholders.
Key improvements in food policy critical for reducing hunger and malnutrition are:
New alliances between public policy and business practice offer partnerships that are vital building blocks for accelerating the joint challenge of reaching Zero Hunger (SDG2).
