Native forest silvopasture extends across an estimated seven million hectares of Argentina, mostly in the northern Chaco region and in Patagonia to the south. As for planted silvopastoral forests, there are an estimated 150,000 hectares, mainly in the regions of Corrientes, Buenos Aires, Misiones and Neuquén.

Animal welfare

Argentina’s National Institute of Agricultural Technology (INTA) is experimenting with a silvopastoral project that expressly promotes animal well-being, according to INTA engineer Edgardo Casaubón. One farm combines forestry, beef farming and beekeeping.

In open fields or in feedlots, if there is a change in temperature, animals can die

Juan Ravalli, a vet from the Ministry of Agribusiness, said about silvopasture: “The animals are in a state of peace and they don’t have heat stroke problems because they have trees.”

Botta added: “In open fields or in feedlots, if there is a change in temperature, animals can die.”

Fewer pesticides, better soils

Another quality of silvopastoral agriculture is its low use of pesticides compared to other forms of livestock rearing. Pesticides are used to maintain the quality of the pasture cows feed on.

Argentina uses more than 300 million litres of agrochemicals per year, nearly nine times more than the 34 million used in 1990. The expansion of silvopasture could help reduce this.

“The use of chemicals is minimal or nil, compared to other livestock systems,” said Casaubón, adding, “Caterpillars are the main pests in the Delta area. Because I have the trees, birds that feed on insects can nest and eat caterpillars. I don’t need to use chemicals.”

The shade that trees offer in silvopastoral systems also changes the composition of the grassland and allows cows to thrive, Botta said.

Trees also help avoid soil erosion, according to Patricia Cornaglia, an expert on silvopastoral systems at the University of Buenos Aires’ faculty of agronomy.

“At the correct distance [they] allow the growth of natural pastures and an undergrowth that serves as a refuge for wildlife,” she said.

Climate change

Cattle farming is one of the main sources of global greenhouse gas emissions, largely because livestock emits methane and nitrous oxide. In Argentina, it is responsible for around 25% of emissions, according to the government.

Cornaglia said that in silvopastoral systems, trees absorb part of the emissions from livestock and could therefore help Argentina reduce its emissions and meet its climate commitments.

Silvopastoral systems could even lead to the production of what its supporters call “carbon-neutral meat”.

Producers calculate livestocks’ annual emissions of methane and nitrous oxide – more potent gases in terms of their planet-warming effects – and work out an equivalent value in terms of carbon dioxide (CO2). Each gramme of nitrous oxide emitted by cows is worth 300 grammes of CO2, while each gramme of methane equates to 25 grammes of C02.

“In Brazil, they estimate that they can compensate for five cows with each hectare of eucalyptus planted,” said Botta. “With 100 hectares they can compensate for 500 cows.”

Such a product would appeal to international markets such as China, where many consumers care increasingly about the climate and environmental impacts of food.

“Cattle fattened by grass are valued because they have no added hormones,” Cornaglia said, adding that other means of fattening cows, such as with genetically modified soybeans, are less desirable.

China exports

Argentina exported a total of 550,503 tonnes of beef in 2018, of which 207,000 tonnes were destined for China. The second largest importer was Russia, which bought 42,380 tonnes. Together, the two countries account for two thirds of exports.

China’s beef consumption has grown by around 30% in the past nine years, driven by demand from the growing middle classes, dietary changes and international marketing efforts by Argentina.

If I used to have natural pastures with a lot of biodiversity and today I have only three species, it’s a disaster

According to Ernesto Fernández Taboada, executive director of the China-Argentina Chamber of Commerce, Argentina has an opportunity to export carbon-neutral meat with silvopastoral certification.

“As long as Argentina can spread the message that part of its production has that certification, it may be of interest to a sector of Chinese consumers who want to consume healthy products. We very much welcome this,” he said.

Criticisms

Despite its benefits, some Argentine environmental organisations have questioned the development of silvopastoral systems.

“When you see a silvopastoral system it is easy to fall in love, everything is divine,” said Pablo Preliasco, head of sustainable livestock at NGO Fundación Vida Silvestre Argentina. “But if I used to have natural pastures with a lot of biodiversity and today I have silvopastoral [farming] with only three species, it’s a disaster.”

Vida Silvestre advocates a silvopastoral system called Forest Management with Integrated Livestock, which according to Preliasco benefits native forest, conserves biodiversity and maintains ecosystem services, whilst producing meat of a higher quality.

However, Noemí Cruz, coordinator of Greenpeace’s forest campaign said even an integrated approach in native forests seems like damage limitation: “Agro-productive development is prioritised more than environmental development and on too large a scale. It doesn’t guarantee the maintenance and regeneration of native forests.”
