The global food system is facing unprecedented challenges that threaten its long-term sustainability and resilience. With the world’s population expected to exceed nine billion by 2050, there is a pressing need to increase food production by 50% to meet rising demand. However, the current agricultural model is contributing significantly to climate change, accounting for a staggering 33% of global emissions. To achieve net zero targets, the food system must undergo a substantial 67% reduction in emissions by 2050.

Disruptions and pressures

The Irish and global food sectors are increasingly susceptible to disruptions arising from a changing regulatory landscape, evolving consumer preferences and the impacts of climate change. While agricultural industrialisation has successfully fed growing populations to date, the current system is under immense pressure and in need of transformation.

Rethinking the value chain

To thrive in this changing food and agri ecosystem, leaders must adopt a holistic perspective that recognises the interconnected network of companies, governments, farms and consumers that collectively influence the fragmented market. Success will depend on developing new ways to exchange value as business models evolve, and exploring opportunities in adjacent industries converging with food such as waste management, last-mile logistics and carbon marketplaces.

Six dimensions for systemic change

We have identified six critical dimensions for driving systemic change across the food domain, presenting both challenges and opportunities for growth:

  1. Healthy and sustainable diets: encouraging dietary patterns that promote human health while minimising environmental impacts, including plant-based and alternative protein sources.
  2. Minimisation of food loss and waste: implementing strategies to reduce food waste throughout the supply chain, from production to consumption, and exploring innovative solutions for repurposing unavoidable waste.
  3. Effective and regenerative agriculture: adopting regenerative agricultural practices that restore and enhance soil health, increase biodiversity and improve water management, while optimising yields and resource efficiency.
  4. Conserved ecosystems and strategic land use: preserving and restoring natural ecosystems, promoting sustainable land management practices, and exploring alternative sources of protein and renewable materials.
  5. Clean energy systems: transitioning towards renewable energy sources and implementing energy-efficient technologies across the food value chain to reduce greenhouse gas emissions and dependence on fossil fuels.
  6. Healthy oceans and blue foods: promoting sustainable fisheries and aquaculture practices that support marine ecosystem health and biodiversity, while exploring alternative sources of seafood and marine-based products.

Collaborating for sustainability

Our insights aim to encourage a collaborative approach among companies, emphasising environmental stewardship and economic viability. By working together, businesses can adapt and thrive, ensuring a robust, equitable and resilient global food system that meets the needs of present and future generations.
