The effect of bioenergy expansion: Food, energy, and environment
Open accessAbstract
The increasing prices and environmental impacts of fossil fuels have made the production of biofuels to reach unprecedented volumes over the last 15 years. Given the increasing land requirement for biofuel production, the assessment of the impacts that extensive biofuel production may cause to food supply and to the environment has considerable importance. Agriculture faces some major inter-connected challenges in delivering food security at a time of increasing pressures from population growth, changing consumption patterns and dietary preferences, and post-harvest losses. At the same time, there are growing opportunities and demands for the use of biomass to provide additional renewables, energy for heat, power and fuel, pharmaceuticals and green chemical feedstocks. Biomass from cellulosic bioenergy crops is expected to play a substantial role in future energy systems. However, the worldwide potential of bioenergy is limited, because all land is multi-functional and land is also needed for food, feed, timber, and fiber production, and for nature conservation and climate protection. Furthermore, the potential of bioenergy for climate change mitigation remains unclear due to large uncertainties about future agricultural yield improvements and land availability for biomass plantations. Large-scale cultivation of dedicated biomass is likely to affect bioenergy potentials, global food prices and water scarcity. Therefore, integrated policies for energy, land use and water management are needed. As biomass contains all the elements found in fossil resources, albeit in different combinations, therefore present and developing technologies can lead to a future based on renewable, sustainable and low carbon economies. This article presents [1] risks to food and energy security [2] estimates of bioenergy potential with regard to biofuel production, and [3] the challenges of the environmental impact.

TL;DR
This review assesses global bioenergy expansion and its implications for food, energy, and environment, concluding that bioenergy has large but limited potential and that integrated land, water, and energy policies are needed. It finds that sustainable bioenergy potential is much lower than technical estimates and that indirect land-use change, food prices, and water scarcity are key risks.
Key findings
- Global technical bioenergy potential estimates span less than 50 to 1500 EJ/year in 2050; sustainability-constrained scenarios indicate 200–500 EJ/year, while some analyses suggest a biophysical upper limit of about 250 EJ/year in 2050.
- Global cropland used for biofuels is about 2.5% (40 million gross hectares), falling to 1.5% net when co-products substitute for grains and oilseeds; by 2050 land for biofuel production would need to rise to around 100 million ha (about 6% of arable land). Global food production must increase by 60% by 2050, with crop yield growth slowing to 0.8% per year (2005/2007–2050) versus 1.7% per year (1961–2007).
- Land-use change contributes about 15% of global GHG emissions; bioenergy-related land-use change represents only around 1% of total land-use-change emissions. Indirect land-use change emissions are reported at 30 to more than 100% of fossil fuel emissions, and indirect emissions are in the order of 10–40% of emissions from substituted fossil fuels. Forest conservation reduces bioenergy supply from about 100 EJ in 2055 to 70 EJ and from about 300 EJ in 2095 to 270 EJ.
- One metric tonne of DDGS can replace on average 1.22 metric tonnes of feed consisting of corn and soybean meal in the United States; accounting for co-products reduces the land required for feedstock cultivation to 1.5% of the global crop area (net land requirement).
Methods
- The paper conducts a meta-analysis contrasting and combining results from various studies, biomass supply scenarios, and global models linked to land, water, energy use, and climate change in terms of food-, energy-, and environmental security.
- Search terms included food-, energy- and environmental security, food demand, yield trends, renewable energy, biomass, biofuels, by-products for livestock feeding from biofuel production, land-use change, biofuels and the environment, sustainability requirements, and climate change mitigation; references covered 2001 to 2013, with supplemental bibliography searches.
- Calculations were made for the land required for cultivation of feedstocks adding by-products substituted for grains and oilseeds; the EU policy objective of 20% GHG emission reductions using 20% renewables by 2020 is also presented.
Limitations
- The paper states that results are potentially biased because studies might differ in their focus on potential or realized effects, their use of different baselines for comparisons, and other background conditions; there is also a lack of available publications related to the feed value of increasing biofuels by-products.
- The paper states that precise quantification of GHG savings for specific systems is often hampered by lack of reliable data, different methods of quantification lead to variation in estimates, and indirect effects are uncertain and vary in time with no fixed indirect emission factor.
- Evident from the text: as a review/meta-analysis, findings depend on assumptions and scenarios in cited studies, and the wide ranges reported (e.g., less than 50 to 1500 EJ/year) limit precision; no new primary experimental data are presented.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
