Making Livestock Sustainable

Stockbreeding generates enormous profits in Latin America, but it also has a broad and varied impact on the environment, which means it must urgently be turned into a sustainable, green-friendly, socially accepted activity. 70 percent of the region’s pasture land suffers moderate to severe degradation.

“Latin America cannot continue to ignore, from a public policy point of view, the challenge of making stockbreeding sustainable,” biologist Javier Simonetti, from the Department of Environmental Sciences in the University of Chile, told IPS. He added that stockbreeding has different costs for the region, “but they can be solved, they can be reduced through mitigation measures…I’m reasonably optimistic.” Simonetti asserted that “stockbreeding generates a set of environmental and social problems that are not effectively addressed by any public policy. With a few incentives, orientations or restrictions, they could go from a problem to at least something neutral.” He pointed out, for example, that some 15,000 litres of water are used for each kilo of meat produced worldwide, and warned that “if we don’t reduce this enormous use of water, things will not go well.” And to do that, “everyone has to sit down and talk.”

According to figures from the United Nations Food and Agriculture Organisation (FAO), 25 percent of the calories and 15 percent of the protein consumed by Latin Americans are of animal origin.

Latin America, home to just 13.5 percent of the global population, produces over 23 percent of beef and buffalo meat and 21.4 percent of poultry at a global level, and is the leading exporter of these products, as well as a major producer and exporter of pork and dairy products. Livestock contributes 46 percent of the region’s agricultural GDP, and is largely concentrated in just five countries, which account for 75 percent of production: Brazil, Uruguay, Paraguay, Mexico and Argentina, in that order. Approximately 80 percent of the region’s livestock producers are small family farmers involved in extensive traditional stockbreeding.

According to FAO figures, the livestock sector plays a big role in climate change, producing an estimated 7.1 gigatons of carbon dioxide equivalent annually, which represents 14.5 percent of human greenhouse gas emissions. Production of beef and cow´s milk is responsible for most of these emissions, contributing 41 and 29 percent, respectively. In Latin America, the areas most susceptible to the expansion of the livestock frontier are the Amazon rainforest in Brazil, the Chaco – a semi-arid expanse of dense thorn scrubland – in Argentina, Paraguay and Bolivia, and arid and semi-arid zones in Argentina and Chile. Because of this, the experts say, decisive action must be taken so that growth in livestock production occurs in an environmentally sustainable manner that contributes, at the same time, to mitigating climate change, combating poverty, and improving human health.

In that sense, small-scale producers are key to attenuating the threats, said FAO animal health officer Deyanira Barrero, “Family livestock farmers are more exposed to the risks caused by climate change, but they are key actors in the mitigation of climate change because a number of their common practices help protect the environment.” According to experts, local knowledge and the diversification of family farming production systems are the key factors in reducing the risks associated with climate change and natural disasters. “Climate change adaptation policies should consider the relation between agro-climatic vulnerability and food security and develop specific programmes for climate change adaptation in rural areas,” Barrero said. This should be done by “increasing the use of adapted local breeds which have been preserved by small-scale producers, as well as by using local drought-tolerant crops that can be used for both human and animal food.” The FAO expert stressed that this is a shared responsibility of society as a whole. “Climate change is a global issue and livestock supply chains are increasingly connected across borders. Thus, to be effective and fair, mitigation measures should also be global,” she concluded.
