At New York Climate Week in September, opinion leaders voiced concern that high-profile events often gloss over the deep inequalities exposed by climate change, especially how poorer populations suffer disproportionately and struggle to access mitigation or adaptation resources. The message was clear: climate policies should better reflect social justice concerns, ensuring they are inclusive and do not unintentionally favor those already privileged.

We believe access to food sits at the heart of this call for inclusion, because everything starts with food: it is a fundamental human right and a foundation for health, education and opportunity. It is also a lever for climate, economic and social resilience.

This makes the global conversation around food systems transformation more urgent than ever. Food systems are under unprecedented strain. Without urgent, coordinated action, billions of people face heightened risks of malnutrition, displacement and social unrest.

Delivering systemic transformation requires coordinated cross-sector action, not fragmented solutions. Food systems are deeply interconnected, and isolated interventions cannot solve systemic problems. The Food and Agriculture Organization’s recent Transforming Food and Agriculture Through a Systems Approach report calls for systems thinking and collaboration across the value chain to address overlapping food, health and environmental challenges.

Now, with COP30 on the horizon, unified and equitable solutions are needed to benefit entire value chains and communities. This is where a systems approach becomes essential.

A systems approach to transforming food and agriculture

Food systems transformation must serve both people and planet. We must ensure everyone has access to safe, nutritious food while protecting human rights and supporting a just transition.

At Tetra Pak, we support food and beverage companies throughout the journey of food production, from processing raw ingredients like milk and fruit to packaging and distribution. This end-to-end perspective gives us a unique view into the interconnected challenges within the food system, and how an integrated approach can help manufacturers reduce food loss and waste, improve energy and water efficiency, and deliver food where it is needed most.

Meaningful reductions to emissions require expanding the use of renewable and carbon-free energy sources. As outlined in our Food Systems 2040 whitepaper,1 the integration of low-carbon fuels like biofuels and green hydrogen, alongside electrification supported by advanced energy storage technologies, will be critical to driving the transition in factories, farms and food production and processing facilities.

Digitalization also plays a key role. Through advanced automation and data-driven insights, solutions like Tetra Pak® PlantMaster enable food and beverage companies to run fully automated plants with a single point of control for their production, helping them improve operational efficiency, minimize production downtime and reduce their environmental footprint.

The “hidden middle”: A critical gap in food systems policy

Today, much of the focus on transforming food systems is placed on farming and on promoting healthy diets. Both are important, but they risk overlooking the many and varied processes that get food from the farmer to the end consumer. In 2015 Dr Thomas Reardon coined the term the “hidden middle” to describe this midstream segment of global agricultural value chains.2

This hidden middle includes processing, logistics, storage, packaging and handling, and it is pivotal. It accounts for approximately 22 percent of food-based emissions and between 40-60 percent of the total costs and value added in food systems.3 Yet despite its huge economic value, it receives only 2.5 to 4 percent of climate finance.4

Policymakers need to recognize the full journey from farm to fork as a lynchpin priority. Strategic enablers such as packaging that protects perishable food and extends shelf life, along with climate-resilient processing technologies, can maximize yield and minimize loss and waste across the value chain. In addition, they demonstrate how sustainability and competitiveness can go hand in hand.

Alongside this, climate and development finance must be redirected to increase investment in the hidden middle, with a particular focus on small and medium-sized enterprises, which make up most of the sector.

Collaboration in action

Investment is just the start. Change depends on collaboration between stakeholders across the value chain: farmers, food manufacturers, brands, retailers, governments, financiers and civil society.

In practice, a systems approach means joining up actors and incentives at every stage.5 The dairy sector provides a perfect example of the possibilities of connecting. We work with our customers and with development partners to establish dairy hubs in countries around the world. These hubs connect smallholder farmers with local processors, providing chilling infrastructure, veterinary support, training and reliable routes to market.6 This helps drive higher milk quality, more stable incomes and safer nutrition for local communities.

Our strategic partnership with UNIDO* is a powerful example of this collaboration in action. Together, we are scaling Dairy Hub projects in Kenya, building on the success of earlier initiatives with our customer Githunguri Dairy. UNIDO plays a key role in securing donor funding and aligning public-private efforts to expand local dairy production and improve livelihoods. This model demonstrates how collaborations can unlock changes in food systems.

COP30 and beyond

Strategic investment can strengthen local supply chains, extend social protections and open economic opportunity, particularly in vulnerable regions. Lasting progress will require a systems approach, with policymakers helping to mitigate transition costs and backing sustainable business models that build resilience across global food systems for generations to come.

As COP30 approaches, we urge policymakers to consider food systems as part of all decision-making, to prevent unintended trade-offs between climate and nutrition goals. We also recommend that COP30 negotiators ensure the Global Goal on Adaptation include priorities indicators that enable countries to collect, monitor and report data on the adoption of climate-resilient technologies and practices by food processors. This would reinforce the importance of the hidden middle and help unlock targeted adaptation finance across the food value chain.

When every actor plays their part, from policymakers to producers, and from farmers to financiers, the whole system moves forward. Only then can food systems be truly equitable, resilient and sustainable, protecting what matters most: food, people and the planet.
