How can we understand the multiple dimensions of transforming food systems? On top of the disruptions to peoples’ incomes and food supply chains caused by COVID, the Russia war in Ukraine has pushed fertilizer, energy and food prices to all-time highs. Millions are falling back into hunger and poverty. Even in the affluent world, many poorer people in society are being forced to use food banks, eat lower nutritional value food, and make tough decisions between using their dwindling financial resources to pay for food or keep their houses warm in winter.  

This situation underscores the conclusions of the UN Secretary General’s 2021 Food Systems Summit that highlighted the need for a far more resilient, equitable and sustainable food system. Heads of state universally declared that a transformation of food systems is needed to cope with climate change, tackle hunger and poor nutrition, reduce poverty, and protect the environment.

But what does food system transformation actually mean? In this blog, I outline a framework (Figure 1 below) for thinking about food systems transformation. It is based on WHY change is needed, WHAT needs to change, and HOW change can be brought about.

Introducing food systems transformation

“Food systems” has provided a new framing for a more integrated approach to the issues of food security and nutrition, agriculture, climate change, environment and rural poverty. This systems view makes a lot of sense as, one way or another, how we consume and produce food is central to all the Sustainable Development Goals (SDGs). Billions of people work in the agri-food sectors, everyone needs a healthy diet, food is central to culture, food trading and retailing are huge markets and agriculture is the biggest user of land and water resources.

This systems perspective is bringing together a plethora of associated ideas, language and concepts. Terms such as food system outcomes, transformation, transition pathways, resilience, equity, trade-offs and synergies, living income, nature positive approaches, agroecology and the true-cost of food are just a few of these. The emerging food systems discourse is also giving more attention to power structures, the political economy, stakeholder engagement and dialogue, empowering excluded voices, market externalities, coalitions, economic incentives, and data needs.

Before explaining the framework, let’s ask what is meant by a transformation of food systems. Transformation means a complete or radical change of something in form, function or appearance. So, transforming food systems means fundamentally changing how they operate to dramatically improve environmental, health and livelihood outcomes for society at large. This requires fundamental changes in the behaviour of consumers, investors, agri-food sector firms, farmers, researchers and political leaders. In turn, a dramatic shift in economic and social incentive structures is needed, with the true cost of food embedded into how markets function. To avoid future risks these fundamental changes are needed with urgency.

To-date, and perhaps not surprisingly, much of the debate and political narrative has focused on what needs to change and why. The more difficult question of how change can actually be brought about has so far received less attention. Perhaps this is because such discussion cannot avoid difficult political-economic issues of long-term collective interests versus short-term vested interests. We are still a long way from having sufficiently detailed strategies, plans of action, policy commitments and investments to bring about the transformation. How to get from WHY to HOW?

WHY transform food systems?

Why food systems need to change has been well analysed, is clear to most stakeholder groups, and is increasingly articulated by political leaders. The problems and longer-term impacts and risks of the way food is currently consumed and produced is well-evidenced in terms of the negative consequences for health, the environment, and equitable economic development. If this interconnected set of issues is not tackled effectively and promptly the risks of dire longer-term social, economic and political consequences are high.

Food value chains contribute about a third of total greenhouse gas emissions. Agriculture and fishing are by far the largest causes of biodiversity loss and ecosystem degradation. These impacts on the environment cycle back to undermine the Earth’s very capacity to produce food for the long run.

Further, it is increasingly clear that the SDGs and in particular SDG1 – no poverty – and SDG2 – zero hunger – will not be achieved without a fundamental change in how food systems function.

The work of the Food Systems Summit brought a much wider understanding and acceptance that the numerous development issues linked to food can only be effectively dealt with through a cross-sectoral and systems-oriented approach. An additional critical aspect of the food systems framing is an acceptance that these issues are of equal importance for countries in the Global North and the Global South.

Foresight and scenario analysis can make a vital contribution in helping to explore the ways food systems might change and with what risks and opportunities for different stakeholder interests.

WHAT needs to be transformed?

The desired outcomes from food systems have become well-articulated in terms of three main areas:

  1. ensuring food security and optimal nutrition for all.
  2. meeting socio-economic goals, in particular reducing poverty and inequalities.
  3. enabling humanity’s food needs to be met within planetary environmental and climate boundaries.

Overall, food systems are recognized as needing to function with the properties of being resilient to shocks, sustainable over the long-term and equitable in terms of the costs and benefits to different groups in society.

Across these food system outcomes and properties, there are inevitable trade-offs and synergies, which bring with them the potential for both conflict and collaboration between different interest groups. While the broad directions for desired food system outcomes and properties are relatively well established, the nature and extent of these synergies and trade-offs is much less well understood. More work is also needed to establish specific criteria, directions for change and targets for food system outcomes, which will be necessary to guide transformation at national or local levels, within sectors or across business operations. More attention needs to be given to how the criteria and targets for food systems transformation align with those of the SDGs.  

The Food Systems Summit and the work of the Committee on World Food Security (CFS), in particular its recently adopted Voluntary Guidelines of Food Systems and Nutrition (VGFSyN), have identified underlying values and principles that should guide the processes and outcomes of food systems transformation. These include human rights (incl. the right to adequate food), sustainability, resilience, transparency, accountability, adherence to the rule of law, stakeholder engagement, gender equality, and inclusivity (particularly for women, youth, indigenous groups and small-scale producers).

Food systems that deliver on the desired outcomes and properties, and function in adherence with the underlying values and principles articulated above, can be considered as sustainable food systems.

HOW can food systems be transformed?

The transformation of food systems will require a focus on transition pathways, largely driven at the national level but connected with local processes and enabled by larger-scale system shifts at regional and global scales. Four main transitions can be identified from the Food Systems Summit deliberations:

  1. a consumption shift to sustainable and healthy diets.
  2. an equitable economic shift to ensure food economy producers and workers, have a fair living income including being able to afford healthy diets.
  3. a shift toward nature positive approaches for food production, processing and distribution which have a net-zero climate impact and operate within a sustainable and safe zone of utilizing natural resources.
  4. a shift towards mechanisms of resilience for food systems which can ensure societies a large to not risk food insecurity and that groups who are poor or vulnerable are protected.

Desired food system outcomes can potentially be achieved through multiple different pathways and scenarios with numerous different trade-offs and synergies. For example, consumption shifts could be influenced by food prices and taxes, public education, product labelling or shifts in food marketing practices. Resource efficiency and circularity could be achieved by a number of measures, including consuming (at a global level) less animal protein, adopting agroecological approaches, energy efficiency, water management, reducing waste, or new technologies which reduce methane emissions from cattle farming. Equity for those working in the sector could be improved through various combinations of increasing food prices, implementation of labour and land tenure rights, improved social protection, improving overall rural economic development or creating greater economic opportunity outside the food sector.

Developing and assessing the options and scenarios to enable transitions is where a vast amount of investment and work is needed if food systems are to be sustainably transformed. The Food Systems Summit process identified a significant number of “game changing solutions”, ideas that could contribute to developing viable transition pathways. Further assessment and work will be needed to refine, prioritize and build on this contribution from the Summit.

Scenarios can help identify potential trade-offs and co-benefits of those solutions across intended food system outcomes. The principles of equity and inclusion are especially important to consider when analysing options and trade-offs. For example, gender equality is not guaranteed to improve with increased income from food systems activities, so attention must be paid to gender-transformative and inclusive value chain development.

Generating viable options for transforming food systems will require systemic innovation that connects processes of innovation across the domains of technology, institutions and social norms, and politics and governance. Food systems transformation will be impeded or enhanced depending on the constellation of power relations across societies and the agri-food sector. This is particularly salient where influential actors are prepared to defend vested interests at the cost of changes for the wider collective good. Such systemic innovation will require profound paradigm shifts and completely new approaches to policy coherence.

Insights from systems theory and transition theory have much to offer in terms of how to guide and broker change in complex (food) systems. For example, encouraging, supporting, linking and scaling up “niche” innovations that can respond to new needs, challenges and opportunities. This requires adaptation to local contexts that can be supported by territorial approaches to development. Over time, such innovations can help to disrupt existing and unsustainable food systems “regimes” (attitudes, policies, power relations, market relations) and enable more sustainable alternatives to become embedded.

The Food System Summit has helped to identify numerous factors that can be considered as enabling conditions or structural constraints for food systems transformation. Systems change involves “nudging” systems in desirable directions by working to amplify enabling conditions and dampening structural constraints. This requires attention to the underlying political economy. Strategic alliances and political leadership are needed to help shift understanding, narratives and power dynamics.

“Food systems” has become the term around which issues of agriculture, nutrition and food security are now being framed.  But what is a food system?  Here I flesh out the details of the conceptual model we are using to underpin the work of Foresight4Food.

The attention to food systems is for good reason. The 2008 food price crisis sparked much concern over global food security. However, the concept of food security tended to be narrowly associated with ensuring people have access to enough food in terms of calories, leaving aside a much wider set of food issues. We now more clearly recognise the “triple-burden” of malnutrition that involves under-nutrition, micronutrient deficiencies and overnutrition. Globally we have an unhealthy imbalance between producing and consuming too much calorie-dense food and not enough nutrient-rich food.  The alarming increase in numbers of overweight and obese people, and the associated rise in rates of non-communicable diseases is one of the consequences. Meanwhile, food production is a major contributor to green-house gases, biodiversity loss, and natural resource degradation, yet despite this pressure on limited resources, it is estimated that a third of food is lost or wasted. These are interlinked problems requiring systemic solutions and a transformation in how our food systems operate.

Let’s back up a moment and consider what we mean by a system. Using classic systems thinking, a system consists of a set of interacting components that transform inputs into outputs/outcomes. A system has a boundary that distinguishes it from the environment in which it operates. Feedback loops between the internal components (sub-systems) and between the system and its wider environment underpin how the system behaves and evolves. Food systems involve the interplay of human and natural systems and as such are complex adaptive systems. This means they have high degrees of complexity, uncertainty and adaptiveness and may evolve in ways that cannot be entirely predicted and controlled through human endeavour.

In developing a systems conceptual model, it is important to remember that it is a simplified tool to help understand and visualise complex sets of relationships. How the conceptual model is constructed depends on human perspectives. Different people or groups may construct different models, and the models’ design is dictated by the question(s) it aims to help address. Such a model is a human construct to aid understanding, and is not a model of “reality”.

As illustrated in the diagram, a set of food system activities are at the core of the food system. These are undertaken by different actors, from primary production, to processing, retailing and consuming along with storage and disposal. In reality, food systems involve multiple interacting value chains. To function, these require a broad set of supporting services including, physical and market infrastructure, transport, financial services, information, and technology. The incentives and operating conditions for the actors are influenced by the institutional environment of policies, rules, and regulations (e.g. food safety and quality, financial, taxation, environment etc.), consumer preferences and social norms (see Woodhill 2010 and 2008).  Together these institutions create the formal and informal “rules of the game” that govern how the food system functions.

The food system operates within a wider context of human systems and natural systems with multiple interactions and feedback loops between these systems. These wider systems create a set of external drivers and their trends that shape the behaviour and evolution of the food system, though each actor in the system will be influenced, and thus react, differently. Drivers include population, wealth, consumption preferences, technological developments, markets, environmental factors and politics. The outcomes of food systems function can be categorised into three main areas: economic and social well-being, food and nutrition security, and environmental sustainability. Fundamental to the systems model is the recognition that food system activities, from farming to eating, are undertaken by actors who have differing interests, influence, power and perspectives.

This model of the food system integrates work by Ericksen (2007), Ingram and Zurek (2018) with the market systems thinking of the Making Markets Work for the Poor (M4P) approach (Springfield 2015). Other food systems models and frameworks include the highly detailed model of ShiftN (2009) , the CGIAR CIAT model and recent framework by Wageningen University and Research (van Berkum et al (2018).

A food systems model, such as this, provides the basis for understanding and exploring the critical relations, trends, and trade-offs that will underpin any desired transformation of how the system works.  For example, indicators for the three outcomes enable an assessment of whether food systems are functioning in desirable or undesirable ways relative to wider societal and environmental objectives. The drivers enable an understanding of the pressures acting on food systems and influencing how they are changing (with these drivers in turn being influenced by the outcomes). The Foresight4Food Beta Data Portrait provides a synthesis of key trends for these food system drivers and outcomes.

Of critical importance is understanding how institutions shape the way the food system behaves and delivers more or less benefits to different actors in the system and the environment. Transforming food systems is largely about institutional innovations to redesign incentive structures, in particular to tackle the market externalities related to negative impacts on human health and the environment. Given the inevitable trade-offs and impacts on vested interests, this is inevitably a highly political exercise which has to play out in a highly value-laden, contested space.
