Global Farm Productivity Growth Slows to 0.63%, Raising the 2050 Hurdle
Global agricultural productivity growth has fallen to its weakest recorded pace since the 1970s, widening the distance between what farms are producing more efficiently and what the food system is expected to need by mid-century.
The 2026 Global Agricultural Productivity Report, published by Virginia Tech and highlighted by the International Institute for Applied Systems Analysis on October 22, found that global agricultural total factor productivity, or TFP, grew by an average of just 0.63% a year during 2015–2024. The report says the annual pace now required through 2050 is 2.10%. The Virginia Tech report repository dates the full report to September 29, while IIASA published its research summary on October 22.
The gap is larger than the headline rate suggests
TFP measures the relationship between all agricultural outputs and the combined bundle of inputs used to produce them, including land, labour, capital and intermediate inputs. It is therefore not the same as crop yield, total farm output, revenue or profit. A country can harvest more by using more fertilizer, water, machinery or land without achieving the same improvement in TFP.
The 0.63% observed pace is exactly 30% of the 2.10% annual rate the report says is now required. That leaves a 1.47-percentage-point annual shortfall. The report also places the recent rate at roughly 30% of the 2001–2010 peak, meaning global productivity growth has lost about seven-tenths of its earlier momentum.
An Agrilinkage compounding illustration makes the scale easier to see. If a productivity index grew at 0.63% for ten years, it would rise by about 6.5%. At 2.10%, it would rise by about 23.1%. The difference would be roughly 16.6 index points after a decade. This is an arithmetic comparison, not a forecast: the required rate can change as demand, population, waste, diets and the underlying data change.
Indicator | Rate or result | Interpretation |
2015–2024 global TFP growth | 0.63% a year | Lowest recorded since the 1970s |
Required through 2050 | 2.10% a year | Report estimate for meeting future demand |
Annual gap | 1.47 percentage points | Observed rate is 30% of the requirement |
Illustrative 10-year compounding | 6.5% versus 23.1% | A 16.6-point difference in the index |
More output is again coming from more inputs
The report estimates that input intensification once again accounts for roughly half of global agricultural output growth. That matters because growth driven mainly by additional inputs exposes producers more directly to volatile fertilizer, fuel, feed and finance costs. It can also be difficult to sustain where land and water are already constrained.
For farmers and agribusinesses, slower TFP growth can show up as pressure on unit costs even when physical output is still rising. For food-importing countries, it can increase exposure to disruptions in energy, fertilizer and shipping. For governments, it raises the cost of trying to expand production through subsidies or resource use without corresponding gains in efficiency.
Regenerative agriculture is a pathway to test, not a measured cure
The report builds a framework connecting regenerative-agriculture practices to productivity and profitability through three channels: reducing purchased inputs, accumulating natural capital that may improve output over time, and stabilizing output under climate stress. The authors find the strongest near-term evidence for input reduction, while soil, ecosystem and stabilization gains tend to emerge over longer periods than standard farm financial models capture.
But the report draws a firm evidentiary boundary: no study has yet directly measured TFP growth attributable to regenerative-agriculture adoption. Outcomes differ by practice, soil, climate, tenure and market access. That means cover crops, reduced tillage, integrated livestock, agroforestry or other practices should not be treated as interchangeable products with a universal return.
The practical question is not whether a practice carries a regenerative label. It is whether, in a defined production system, it reduces the full input burden, protects output during stress, improves the productive asset base and delivers a return after transition costs and risk are counted.
The EU evidence challenges payment design
A European Union analysis in the report uses three decades of farm-account data across 213 farming regions. It finds no consistent relationship between the intensity of agri-environment and climate payments and TFP growth. In the EU case, the report says TFP growth is now the only remaining source of agricultural output growth.
The result does not show that environmental payments never work, nor does a regional association establish what caused productivity to rise or fall. It does suggest that spending intensity by itself is a weak performance test. The IIASA authors argue for outcome-linked payments supported by monitoring and verification, so programs can distinguish activity from measurable changes in productivity and environmental condition.
What changes for farms, investors and policy
The report identifies three sequential bottlenecks: the evidence and data base, usable farm decision tools, and the policy and market environment needed to finance adoption. Its five priorities are harmonized monitoring, reporting and verification; long-duration whole-system trials; localized decision tools delivered with extension; transition finance matched to risk; and target-based frameworks that include TFP growth as an outcome.
Those priorities point to a different investment test for agricultural technology. A tool should be judged not only by a plot-level yield response, but by whether it changes total input use, labour, capital requirements, variability and profitability over several seasons. The same logic applies to public programs: acreage enrolled and money disbursed are inputs, not proof of productivity or resilience.
The transition-finance issue is especially important. Practices that lower fertilizer or feed bills quickly may be easier to finance than changes whose benefit is improved soil function or lower yield volatility several years later. Without longer contracts, insurance design or patient credit, producers may rationally reject practices that have positive long-run value but concentrate risk in the first seasons.
Limits and indicators to watch
TFP is a powerful broad measure, but it is not a complete scorecard. Cross-country estimates depend on the quality and comparability of output and input data, and they may not fully price soil degradation, biodiversity, water depletion or pollution. Aggregate rates can also conceal large differences among commodities, farm sizes and regions.
Readers should therefore watch for revisions to the global TFP series, long-run trials that measure whole-system inputs and outputs, and published monitoring protocols that can compare practices across locations. Evidence that directly links regenerative adoption to TFP, rather than to one yield or soil indicator, would materially strengthen the case. So would transparent reporting of transition costs, failure rates and the distribution of gains between landowners, operators and buyers.
The central finding is not that the world has stopped producing more food. It is that a growing share of output growth is again coming from using more resources, while the efficiency component has slowed sharply. Closing that gap will require better measurement and farm-level economics as much as new technology or larger budgets.
