The most striking changes concern livestock. Under a scenario aligned with a 2025 EAT–Lancet Commission-style transformation, the global value of livestock production could decline by 42% ($630 billion) by 2050. The authors attribute this to reductions in ruminant demand as diets move away from high-impact foods.

For ruminants specifically, production value is projected to drop by 70% ($274 billion), alongside 400 million fewer ruminant animals globally by 2050. In parallel, the value of vegetable, fruit, nut, and legume production is projected to rise by 57% ($890 billion), reflecting demand shifts toward plant-rich diets.

The modeling was led by researchers from the London School of Hygiene & Tropical Medicine (LSHTM) and Cornell University, alongside 10 independent modeling teams. The work is presented as computational simulation, exploring how large-scale diet transitions interact with agricultural production, land use, and greenhouse-gas pathways.

Importantly, the authors link the transformation to climate mitigation: agriculture-related net CO2 emissions from land-use change could fall by 85% by 2050 relative to 2020. The analysis also draws on the EAT–Lancet framework’s health premise, where healthier eating patterns could reduce premature deaths by an estimated 15 million per year.

The paper emphasizes that these results are not a forecast but an “early guide” to where shocks and opportunities may arise. Governments, the researchers argue, must act before 2050 because the sectoral contractions and expansions required by such a transformation would begin well before the target date.

Regional outcomes vary sharply. The US agricultural production value is projected to decline by 21% ($76 billion), with crop value rising by 20% while livestock value falls by 73%. India shows the opposite direction overall, with agricultural value increasing by 46% ($198 billion), crop value up 65%, and livestock value down 8%.

In the scenario for Europe, total agricultural value falls by 35% ($190 billion), driven by an especially steep livestock decline. The authors caution that the model assumes a costless shift in consumer preferences, even though affordability, accessibility, and cultural food habits will complicate real-world adoption.

Overall, the study argues that timely policy choices could protect vulnerable producers and consumers while accelerating a shift toward healthier, more sustainable, and more equitable food systems.

The cornerstone of this analysis reveals that each degree Celsius increase in global average temperature is expected to diminish the world’s capacity to produce calories by approximately 120 calories per person per day. Translated into more tangible terms, this represents a 4.4% reduction of current average daily caloric intake per individual. Solomon Hsiang, a senior author of the study and professor at Stanford’s Doerr School of Sustainability, characterizes these losses as equivalent to the entire global population sacrificing their daily breakfast should global warming reach 3 degrees Celsius. This analogy illustrates the severity of food consumption reductions expected if urgent and effective mitigation and adaptation strategies are not implemented.

The implications of such production declines are not merely hypothetical. With an estimated 800 million people enduring hunger or food insecurity on any given day, the prospect of decreasing crop yields exacerbates an already dire humanitarian crisis. Southeast Asia and Sub-Saharan Africa, regions heavily reliant on subsistence farming and vulnerable to climatic volatility, could face severe yield reductions, particularly in resource-critical crops such as cassava. These yield shortfalls pose risks for both subsistence livelihoods and broader regional stability, amplifying the urgency for targeted interventions that address the intersection of climate change and food access.

From a policy perspective, the new dataset offers powerful insights ahead of the forthcoming COP30 summit in Brazil, emphasizing the tangible impact of greenhouse gas emissions trajectories. The dataset models two emission scenarios: one involving aggressive emission reduction resulting in net-zero carbon outputs, and a second with continued high emissions. Under the net-zero scenario, global agricultural yields are predicted to decline by 11%, whereas the business-as-usual pathway projects a near doubling of loss to 24%. Crucially, these declines appear irrespective of national wealth, indicating that no country is immune to the climate-driven agricultural crisis.

The study’s scope covers six vital staple crops—corn, rice, wheat, soy, cassava, and sorghum—providing subnational resolution for over 19,000 regions across more than 100 countries. This high-resolution approach enhances understanding of the spatial variability in climate impacts on global food systems and aligns agricultural projection models with realistic adaptation measures farmers are likely to undertake. Adaptation strategies such as modifications in planting calendars, crop varietal shifts, and fertilizer application adjustments offer some mitigation potential but are estimated to offset only about one-third of the projected climate-related yield losses by the end of the century.

Notably, the analysis identifies that rice yields may experience less pronounced declines compared to other staples. However, crops like corn and soy, which underpin global commodity markets and food supply chains, face a more consistently high probability—ranging between 70 to 90 percent—of yield reductions by 2100 across various emission scenarios. This signals heightened vulnerability for key global breadbaskets, affecting food security beyond national boundaries and threatening international trade flows and economic interdependence.

The U.S. Corn Belt, traditionally regarded as one of the most productive agricultural regions worldwide, is projected to experience severe yield contractions under significant warming scenarios, with potential drops reaching 40%. This raises questions about the long-term sustainability of these prime agricultural zones and suggests a possible shift in geographic patterns of productivity globally. Such transformation will likely cascade into food price volatility and policy challenges pertaining to food distribution and rural economies dependent on agriculture.

The Climate Impact Lab’s commitment to translating this data into actionable policy guidance is exemplified through collaborations with governmental bodies to optimize adaptation investments. Recognizing the technological and informational barriers faced by millions of smallholder farmers—such as limited access to precise weather information—is essential for enabling adaptive capacity. The Energy Policy Institute at the University of Chicago (EPIC), home to the Climate Impact Lab, drives efforts to bridge this gap by integrating scientific data with practical applications.

In tandem, the Human-Centered Weather Forecasts (HCF) Initiative pioneered at the University of Chicago demonstrates innovation in harnessing artificial intelligence to provide hyper-localized, climate-sensitive forecasting tailored to farmers’ decision-making processes. Their recent collaboration with the Indian government delivered early monsoon onset forecasts to nearly 38 million farmers, significantly enhancing their ability to align planting decisions with anticipated weather patterns. As climate change intensifies the unpredictability of weather systems, such anticipatory tools become indispensable for sustaining agricultural productivity and livelihoods.

The convergence of climate science, social science, and technological advancement embodied by this dataset and its associated initiatives represents a vital step toward holistically addressing the multi-dimensional risks posed by climate change. It underscores the critical imperative for coordinated global action encompassing emission reductions, innovative adaptation technologies, and socio-economic strategies to buffer vulnerable populations. The human development stakes are immense, with agricultural yields underpinning food security, economic vitality, and overall well-being.

Ultimately, this dataset serves as a clarion call for policymakers, researchers, and communities worldwide. It illuminates the urgent need to accelerate transformative policies and investments that safeguard agricultural systems and human development from escalating climate disruptions. Without concerted global efforts, the vision of a stable, equitable, and nutritious food future may slip further out of reach—threatening both current and generations yet to come.

Harsh Bais, a distinguished professor of plant biology at the University of Delaware and an esteemed recipient of the Innovation Ambassador award, underscores a critical, yet largely neglected, challenge in contemporary agriculture: the deficiency of nutrient-enhanced staple crops. As global populations surge towards an anticipated doubling by 2050, the pressure mounts to not only increase food quantity but elevate the nutritional quality of crops. Despite the emphasis on maximizing yield, the cultivation of nutrient-dense plants has not been adequately incentivized nor integrated into mainstream agricultural practices. This oversight presents a looming threat to global food security and nutritional health.

Central to human nourishment are amino acids, essential components that the body requires for synthesizing proteins. Staple crops such as corn, wheat, and soybeans form the cornerstone of diets worldwide; however, the prevailing production paradigms prioritize volume over nutrient composition. This paradigm perpetuates widespread nutrient deficiencies and undermines efforts to combat malnutrition on a global scale. Bais and his colleagues argue that a shift towards breeding and cultivating crops with enhanced nutrient profiles is vital to future food security and public health.

In a groundbreaking study published in Frontiers in Microbiology, Bais teamed up with researchers from the University of Delaware, Stroud Water Research Center, and the Rodale Institute to investigate the influence of soil-borne microbes on crop nutrient enrichment. Their research focused on a beneficial soil bacterium, Streptomyces coelicolor M145, and its capacity to augment levels of ergothioneine—a powerful amino acid antioxidant—in spring wheat, one of the globe’s most widely consumed cereal grains. The study was supported by funding from the U.S. Department of Agriculture and the Foundation for Food and Agriculture Research, reflecting the importance of this novel line of inquiry.

Employing rigorous laboratory-based experimentation, the researchers germinated spring wheat seeds, allowing seedlings to develop for seven days before introducing the S. coelicolor bacterial strain to the root systems. Subsequent analyses involved isolating the plant’s roots and shoots to extract and quantify ergothioneine concentrations. The results were compelling: within ten days post-inoculation, the bacteria successfully colonized both root and shoot tissues of the spring wheat. Remarkably, this colonization facilitated ergothioneine production despite the plant’s complex innate defense systems, effectively fortifying the plant’s nutritional status.

The ability of S. coelicolor to circumvent and bypass the multifaceted defensive layers of the plant—numbering in the thousands—suggests a finely balanced evolutionary mutualism, where both microbe and host derive benefits. This mutual advantage principle exemplifies a sophisticated biological partnership, paving the way for innovative agricultural strategies that exploit natural microbial relationships to enhance crop nutrient profiles. This approach departs from traditional genetic or chemical modification methods, aligning more closely with ecological principles and sustainable farming paradigms.

By harnessing such microbial associations, scientists envision a transformative method to elevate protein and antioxidant content in cereal crops, which historically exhibit lower nutritional density compared to other food groups. This strategy has the potential to radically shift agricultural production towards nutrient fortification, contributing to the mitigation of nutrient deficiencies and improving global health outcomes. Given rice and cereals constitute a primary dietary staple for billions, the implications for public health are profound.

Bais emphasizes the critical role of the plant rhizosphere—the soil microenvironment surrounding roots—in mediating these microbe-plant interactions. Engineering this zone by promoting beneficial microbial consortia could foster enhanced nutrient uptake and plant growth traits. This rhizosphere manipulation represents a promising frontier in agricultural biotechnology and sustainable crop production, offering a non-invasive, ecologically sound pathway to boost soil and plant health symbiotically.

Additional concerns arise from the ongoing effects of climate change, which experiments led by Alex Pipinos, the study’s lead author and a University of Delaware microbiology graduate, identify as a key factor in declining nutrient density of crops. Elevated temperatures and environmental stresses have degraded the nutritional quality of staple foods globally. Pipinos highlights the significant connection between soil microbial health, plant vitality, and human nutritional benefits—asserting that enhancing ergothioneine content within plants could provide substantial protective effects against cardiovascular disease and cognitive decline.

The functional properties of ergothioneine extend beyond basic nutrition; it acts as a potent antioxidant, mitigating oxidative stress linked to aging and chronic diseases. By amplifying ergothioneine levels naturally within crops, this microbial-plant partnership holds promise for advancing public health, particularly in vulnerable populations facing nutritional shortages. Stresses such as drought and heat, anticipated to intensify with climate change, may be better managed through these fortified plant-microbe relationships, potentially improving crop resilience alongside nutritional value.

Andrew Smith, co-author and Chief Scientific Officer of the Rodale Institute, attests to the pivotal role of soil health in this nutritional paradigm shift. He poses a crucial question: how can agricultural practices evolve to sustain and expand the production of essential phytonutrients like ergothioneine? Smith frames this investigation as foundational and anticipatory—the commencement of research trajectories that may redefine farming systems, food production, and ultimately human health through biofortification and sustainable microbiome management.

Looking forward, Bais and his team plan to extend their research into field trials under environmental stress conditions such as elevated temperatures and water scarcity. Understanding the mechanistic underpinnings of ergothioneine’s uptake and function within plants, as well as the subtleties of microbial colonization amidst plant defenses, remains a central aim. This may ultimately unlock new agricultural methodologies tailored to future climatic challenges while simultaneously enhancing the nutritive quality of staple crops critical to global populations.

This research reveals intriguing possibilities where sustainable microbiology, plant science, and nutritional biochemistry converge. It exemplifies an innovative approach to confronting food insecurity, not solely by augmenting yield but by elevating the intrinsic nutritional architecture of the crops themselves. The promise of microbial facilitation of nutrient biofortification could mark a paradigm shift in agronomy and food sciences, bearing significant implications for enhancing human health on a planetary scale.
