In an era marked by unprecedented challenges, our global food systems stand at a crossroads. These networks that feed the world are currently burdened by inefficiencies, environmental degradation, and vast inequalities. Yet within this crisis lies a powerful opportunity: to transform broken systems into engines of shared prosperity.
The hidden costs of inaction are staggering, totaling up to 12% of 2020 global GDP each year. Conversely, a coordinated transformation could unlock as much as $10 trillion annually in health, economic, and environmental gains. This article explores the urgent need for change, the scale of the challenge, and the pathways that can lead us to a more secure and abundant future.
Today, more than 318 million people face crisis-level hunger or worse. This figure has more than doubled since 2019, reflecting a 20% increase in acute food insecurity since 2020. Sixteen countries are identified as hunger hotspots, with confirmed famines in Gaza and Sudan—the first this century.
Beyond immediate hunger, malnutrition takes multiple forms. Approximately 783 million individuals experienced hunger in recent years, an increase of 122 million from 2019. Meanwhile, 3.1 billion people—42% of the global population—are unable to afford a healthy diet. Alarmingly, obesity now affects over one billion people, while 390 million remain underweight.
The drivers of this crisis are complex and interlinked: conflict remains the primary cause, while climate change, the fallout from COVID-19, inflation, and social unrest further weaken resilience. At the same time, food systems are a major environmental burden, responsible for over one-third of greenhouse gas emissions, up to 80% of biodiversity loss, 70% of freshwater use, and 90% of deforestation linked to agriculture.
As the world’s largest economic sector, agriculture and food systems sustain the livelihoods of half the global workforce. Approximately 1.3 billion people are directly employed in farming, fishing, and food production, while another 1.3 billion depend on these activities for their income.
In the United States alone, agriculture contributes 5.5% of GDP and accounts for 10.4% of employment. However, this scale belies persistent inequities. Up to two-thirds of the extreme poor live in agricultural households, struggling with limited access to education, infrastructure, and fair market prices.
The hidden costs of current food systems are not borne equally. Lower-income communities face a disproportionate burden of diet-related chronic diseases, reduced productivity, and environmental harms. Without significant reforms, these inequalities will deepen, trapping millions in cycles of poverty and poor health.
Adopting a "Food System Transformation" pathway can reverse these trends and deliver $5–10 trillion in annual benefits. By 2050, this strategy aims to eradicate undernutrition, save an estimated 174 million lives from diet-related diseases, and shift food systems towards net carbon sinks by 2040.
This pathway envisions protecting 1.4 billion hectares of land, halving nitrogen surpluses, and restoring biodiversity. It also seeks to ensure that 400 million farm workers earn sufficient income to lift families out of poverty. Achieving these goals would require a modest investment of 0.2–0.4% of global GDP.
Such transformation supports multiple Sustainable Development Goals simultaneously, touching on climate action, health, and poverty alleviation. Importantly, while commodity prices may rise by 30% by mid-century, projected income gains and productivity improvements would more than offset these increases, keeping food affordable for vulnerable populations.
Recent market analyses indicate that global food supplies remain well-stocked. As of December 2025, wheat and rice prices are easing, maize markets are stable, and soybean prices are climbing due to shifting demand. Fertilizer costs have also begun to decline, though they remain high enough to constrain smallholder investments.
Looking ahead, the U.S. Department of Agriculture’s Economic Research Service projects food price inflation of 2.7% for 2026, with food-at-home costs rising 2.3% and dining-out expenses increasing by 3.3%. These figures reflect a slight moderation from 2025’s 3.0% overall rise but still underscore persistent affordability challenges.
International initiatives are already paving the way for more resilient and equitable food systems. The World Bank’s Food Systems Resilience program, with a $2.75 billion investment in Eastern and Southern Africa, focuses on crisis response, climate-smart agriculture, and market development.
Additional World Bank efforts include a $766 million package for West Africa, targeting digital agricultural services and policy reforms, and dedicated funds in Jordan and Bolivia to bolster climate resilience, market access, and inclusion.
As institutions face budget constraints and aid landscapes shift, the imperative to build self-sustaining food systems grows ever more urgent. WFP and FAO forecasts warn of worsening hunger without innovative solutions and renewed policy commitments.
Embracing transformational pathways offers a compelling economic case: for every dollar invested, societies can reap multiple dollars in health, environmental, and social returns. By integrating food system reforms with energy and digital transitions, policymakers can achieve rapid progress toward the SDGs.
However, risks remain, including potential price spikes during the transition and geopolitical tensions that threaten supply chains. Ensuring that the poorest populations benefit will require targeted support, inclusive governance, and resilient infrastructure.
Ultimately, harvesting prosperity depends on collective action across sectors and borders. By reimagining food systems as foundations for shared security, we can cultivate a future where healthy diets, thriving ecosystems, and economic opportunity flourish hand in hand.
