How Much Deforestation Is Caused By Animal Agriculture
Summary
Since the turn of the millennium, the earth has been losing around five million hectares of wood every year. Most all of this occurs in the tropics; most half of all deforestation takes place in Brazil and Indonesia.
Three-quarters is driven by agriculture. Beef production is responsible for 41% of deforestation; palm oil and soybeans business relationship for some other xviii%; and logging for newspaper and wood across the tropics, another 13%. These industries are also dominant in a few key countries.
Effective solutions volition exist focused on these agricultural activities and those countries where most deforestation occurs.
Every year the world loses around v million hectares of forest. 95% of this occurs in the tropics. At least three-quarters of this is driven by agriculture – clearing forests to grow crops, enhance livestock and produce products such every bit paper.1
If nosotros want to tackle deforestation nosotros need to empathize ii central questions: where we're losing forests, and what activities are driving information technology. This allows us to target our efforts towards specific industries, products, or countries where they will accept the greatest affect.
In a written report published in Global Environmental Alter, Florence Pendrill and colleagues addressed both of these questions.2 They quantified how much and where deforestation occurs from the expansion of croplands, pasture and tree plantations (for logging), and what products are grown on this converted state. They also combined this with global trade flows to assess how much of this deforestation was driven by international trade – we wait at the role of trade specifically in a related article.
Here we'll wait at both where tropical deforestation is happening and what products are driving it.
Brazil and Indonesia account for almost half of tropical deforestation
The study by Pendrill et al. (2019) establish that, between 2005 and 2013, the tropics lost an average of 5.v million hectares of woods per year to agricultural land. That was a decade ago, but the world is still losing a similar corporeality today: using satellite data, researchers at Global Wood Lookout estimate that global deforestation in 2019 was around 5.four million hectares.3 95% of this was in the tropics. Only where in the tropics did we lose this forest?
In the chart nosotros come across the share of tropical deforestation by state and region. It's measured equally the almanac average between 2010 and 2014.
One-third of tropical deforestation happened in Brazil. That was 1.vii million hectares each yr. The other single country where large forest areas are lost is Republic of indonesia – it accounted for 14%. This means effectually half (47%) of tropical deforestation took identify in Brazil and Republic of indonesia. Again, if nosotros look at more than contempo satellite data we find that this is all the same true today: in 2019, the earth lost 5.4 meg hectares to deforestation, with Brazil and Republic of indonesia accounting for 52% of it.4 As we will come across afterwards, the expansion of pasture for beef product, croplands for soy and palm oil, and increasingly conversion of main forest to tree plantations for paper and lurid have been the key drivers of this.
The expansion of pasture lands accept also had a major impact on land use in the residue of the Americas – outside of Brazil, Latin America deemed for around one-fifth of deforestation.
The expansion of agricultural land in Africa accounted for around 17.5% of deforestation. This may slightly underestimate the loss of forests in Africa, for two reasons. Much of Africa'south deforestation has been driven by subsistence agronomical activities, which are non ever fully captured in national statistics. Secondly, depending on the permanence of agricultural activities such every bit slash-and-burn farming, some of this forest loss might exist classified as temporary wood degradation rather than permanent deforestation.
Beef, soy and palm oil are responsible for 60% of tropical deforestation
If we want to tackle deforestation we as well need to know what causes it. That allows us to avoid the foods that bulldoze deforestation or innovate the ways nosotros produce them.
In the chart here nosotros come across the breakdown of tropical deforestation past the types of agricultural output.
Beef stands out immediately. The expansion of pasture state to heighten cattle was responsible for 41% of tropical deforestation. That's 2.1 meg hectares every year – near one-half the size of kingdom of the netherlands. Near of this converted state came from Brazil; its expansion of beef production accounts for one-quarter (24%) of tropical deforestation. This also means that most (72%) deforestation in Brazil is driven past cattle ranching.5 Cattle in other parts of Latin America – such as Argentina and Paraguay – also accounted for a large corporeality of deforestation – 11% of the total. Most deforestation for beef therefore occurs in Latin America, with another 4% happening in Africa.
Palm oil and soy frequently claim the headlines for their environmental touch. They are categorised every bit 'oilseeds', which also include a range of smaller commodities such as sunflower, rapeseed, and sesame. They drove xviii% of deforestation. Here we see that Indonesian palm oil was the biggest component of this. In neighbouring Malaysia the expansion of oil seeds was also a major driver of forest loss. Soybeans are the most common oilseed in Latin America. While many people immediately think of food products such as tofu or soy milk, most of global soybean production is used as feed for livestock, or biofuels. Only half dozen% is used for direct human being food. The affect of soy production is one we expect at in more detail in a related article.
Combined, beef and oilseeds account for about 60% of deforestation.
If we add together the third largest driver – forestry products, which is dominated by paper but also includes timber – then we cover virtually three-quarters. Across Europe and North America, forestry products mainly come from managed plantation forests that accept been established for a long period of time, or are grown on previously unforested state. This is different from most tropical countries where forestry products also come up from the logging of principal rainforests or their replacement with plantations. This destroys principal rainforests and, as shown in the nautical chart, has been an of import commuter of deforestation in Indonesia and elsewhere in Asia.

We can tackle a lot of deforestation past focusing on a few key supply chains
If almost three-quarters of tropical deforestation is driven by the production of a few key products – beef, soybeans, palm oil, and paper – and then we tin achieve a lot past focusing our efforts on these supply chains.
At that place are some signs that progress is possible. Soybean production in Brazil was once as well an important driver of deforestation in the Amazon region.6 In 2006, under pressure level from retailers and NGOs, the world's major soybean traders signed Brazil's Soy Moratorium (SoyM) – the world'south first voluntary nix-deforestation agreement. Traders agreed that they would not purchase soy that was grown on deforested lands in the Brazilian Amazon after July 2006. Overall, it was a success: in the two years before the understanding, thirty% of soybean expansion in the region came at the expense of forest; afterwards, deforestation declined dramatically and by 2014 only one% of expansion was turning forests into land for oilseed production.7,eight
But, equally we prove in our article on the impact of soy, in that location are also lessons to learn virtually how to implement these commitments more than effectively. In that location is evidence that while the moratorium reduced deforestation rates in the Brazilian Amazon, some of this deforestation may have 'leaked' to neighbouring regions. Soybean production has shifted from the Amazon to the Cerrado region south of the Amazonas, oft at the expense of forests at that place.9 This suggests that cipher-deforestation agreements can be constructive only must be considered in the wider context of how they shape wood and agricultural changes elsewhere. To combat this, researchers accept suggested the SoyM be expanded to non but include the Amazon merely also regions such every bit the Cerrado.x
If we can have similar activity in the other industries – beefiness, palm oil and paper – then there is the potential to cut out a big share of deforestation today.
Looking to the future, a shift in focus towards Sub-Saharan Africa looks likely. The demands for increased agricultural product in Africa are going to exist big, and could come at the cost of forests.eleven Solutions in that location volition have to focus on major improvements in ingather yields so African farmers tin can produce more than food without increasing the amount of land they need to exercise so.
Culling means of making high-quality poly peptide could also be transformative. Beef is the leading driver of deforestation, and the demand for meat across the world will go along to grow in the coming decades. Technological innovations in meat substitute and cultured meat products would allow people to proceed eating meat-like products without the destruction of tropical forests that come with it.
