Deforestation, the Amazon, and the beef-soy complex

Tropical deforestation is not a random misfortune of poor land stewardship. It is a traceable consequence of global demand for a short list of commodities, and within that list, cattle and soy sit at the top. The Amazon basin and the neighbouring Cerrado tell the story most clearly: forests and savannas converted, year after year, into pasture for beef and fields of soy destined mostly for animal feed. Understanding that chain — and the policies now trying to break it — is central to any honest account of food’s environmental footprint.

The dominant drivers

Curtis et al. (2018) mapped the drivers of global forest loss and found that commodity-driven deforestation — permanent conversion for agriculture, rather than forestry rotation or wildfire — accounts for roughly a quarter of all forest loss and virtually all of the loss in the tropics. In the Brazilian Amazon specifically, the drivers collapse to two. Skidmore et al. (2021) estimated that about 80% of deforested Amazon land becomes cattle pasture, and much of the remainder is soy, often on land that was pasture first. Cattle clear the forest; soy follows behind.

Pendrill et al. (2019), analysing trade data and land-use change for 2005–2013, concluded that agricultural and forestry commodities drove roughly 29–39% of tropical deforestation-related carbon emissions through international trade, with beef and oilseeds the dominant categories. Around three-quarters of global soy is crushed into meal for livestock feed (Song et al., 2021). The protein on European and Chinese farms — pork, poultry, dairy, farmed fish — is, in a real accounting sense, partly made of South American forest.

The Amazon and the Cerrado

The Amazon is the better-known biome, but the Cerrado — the vast tropical savanna to its south and east — has been losing vegetation faster on a percentage basis. MapBiomas records show the Cerrado has lost roughly half of its native cover, much of it to soy expansion, while the Amazon has lost about 20% of its original forest. INPE’s PRODES satellite programme, which has monitored Amazon deforestation since 1988, documented a sharp acceleration between 2019 and 2022 followed by steep declines in 2023 and 2024 under renewed enforcement.

Because the Cerrado is a savanna rather than a closed-canopy forest, it has historically received less policy protection and less consumer attention — and the soy industry has exploited that asymmetry. Song et al. (2021) documented massive soy expansion across South America since 2000, with the Cerrado and the Chaco bearing a disproportionate share. The biome is not a forest in the colloquial sense, but it stores substantial carbon below ground, recharges aquifers that feed much of Brazilian agriculture, and holds thousands of endemic species. Losing it is not a lesser problem than losing the Amazon; it is the same problem in a different ecosystem.

The Soy Moratorium (2006)

In 2006, under pressure from a Greenpeace campaign and European buyers, the major soy traders operating in the Brazilian Amazon agreed not to purchase soy grown on land deforested after July 2006. Gibbs et al. (2015), reviewing a decade of satellite data and trader records, concluded that the Soy Moratorium was strikingly effective inside the Amazon biome: the share of soy expansion occurring on recently deforested land collapsed from around 30% before the agreement to roughly 1% afterwards, even as the total soy area continued to grow on already-cleared land.

The Moratorium is often cited as the clearest example of a supply-chain agreement that actually moved a deforestation curve. But its scope is also its limitation. It covers only the Amazon biome, not the Cerrado. It covers only soy, not the cattle that typically clear the land first. And its displacement effects — soy expanding into the Cerrado rather than the Amazon, or cattle pushed deeper into the forest frontier — are real and quantifiable. The Moratorium proved a mechanism; it did not, by itself, solve the problem.

Cattle and the laundering problem

Cattle supply chains have been harder to clean than soy because they are more fragmented and more opaque. An animal may be born on one ranch, fattened on a second, and finished on a third before slaughter, and Brazilian monitoring agreements historically only covered the final property. Rajão et al. (2020) used georeferenced property and cattle-movement data to show that a substantial share of the beef and soy exported from the Amazon and Cerrado originated on properties with illegal deforestation, with laundering through clean intermediate ranches masking the origin. Their estimate — around 20% of soy exports to the EU and at least 17% of beef exports carried deforestation risk — challenged the industry narrative that certified supply chains were largely clean.

Skidmore et al. (2021) reinforced the point from the cattle side, showing that indirect suppliers — the breeding and rearing ranches upstream of the fattening operations that slaughterhouses actually audit — are where most deforestation-linked cattle enter the chain. Any credible zero-deforestation claim for beef has to trace back through at least three property transfers. Most claims in the market today do not.

EU Deforestation Regulation (2023/1115)

Regulation (EU) 2023/1115, adopted in 2023 and now in its implementation phase, is the most ambitious attempt to legislate deforestation out of a major import market. It covers seven commodities — cattle, soy, palm oil, cocoa, coffee, rubber, and wood — and requires operators placing these products on the EU market to demonstrate through geolocated due-diligence statements that the goods were not produced on land deforested after 31 December 2020. Unlike earlier voluntary agreements, it applies to degradation of forests as well as outright clearing, and its penalties scale to company turnover.

The regulation is not without problems. Its initial definition of “forest” excludes the Cerrado, which is classified as “other wooded land,” echoing the old blind spot of the Soy Moratorium. Its implementation has been delayed, and traceability in cattle supply chains remains technically difficult. Smallholder producers in exporting countries have raised legitimate concerns about compliance costs. But it establishes the principle that market access to one of the world’s largest consumer blocs is conditional on a clean land-use record — a principle that voluntary commitments had left permanently negotiable.

What “deforestation-free” beef actually means

The phrase deforestation-free, applied to beef, can mean very different things depending on who is using it. At its weakest, it means the final fattening property had no recent clearing on its own boundaries, ignoring the breeding and rearing ranches upstream. At its strongest, it means every property in the animal’s life cycle has been monitored, cross-checked against satellite records, and verified back to a fixed cutoff date across the whole biome — Amazon and Cerrado included.

Most commercial claims sit closer to the weak end than the strong end. The gap between them is where most laundering happens (Rajão et al., 2020; Skidmore et al., 2021). A genuinely deforestation-free claim for Brazilian beef requires full-chain geolocation, coverage of indirect suppliers, and enforcement against properties with embargoed areas or illegal clearing. The technology to do this exists — MapBiomas, PRODES, and animal-movement registries provide the inputs — but it has not been the industry default.

The leverage of diet

All of this matters because the most direct way to remove embedded deforestation from a diet is to eat less of the products that drive it. Pendrill et al. (2019) found that beef and animal-feed oilseeds together account for the majority of commodity-driven tropical deforestation emissions. A shift away from beef, and from the animal products fed on tropical soy, reduces demand at the root rather than relying on downstream certification to function perfectly in chains that have repeatedly shown they do not.

The Amazon and the Cerrado are not doomed, and policy tools are finally catching up to the geography. But the cleanest leverage any individual has on tropical deforestation is not waiting for a regulation to reach full enforcement — it is eating in a way that stops asking the forest to carry the calorie.
