Mitigación del Metano del Sector Agroalimentario Una Estrategia Global de Salud

The report identifies livestock fermentation, rice cultivation, and land-use changes as primary drivers of agri-food methane emissions. It argues that transitioning to plant-rich diets, improving livestock management, and adopting sustainable rice farming can reduce greenhouse gases while improving public health by reducing air pollution and non-communicable diseases.

• The agricultural sector accounts for approximately 42% of anthropogenic methane emissions, with 29% specifically resulting from enteric fermentation in ruminant livestock and 3% from livestock manure decomposition.
• Rice cultivation contributes between 8% and 10% of global methane emissions due to the anaerobic conditions in flooded paddies, although it is significantly more land-efficient per calorie than beef production.
• Land-use changes, particularly the conversion of tropical forests, swamps, and peatlands for livestock, food crops, and palm oil, release stored carbon and methane. In Indonesia, a single palm oil plantation expansion contributed between 18% and 22% of the country's annual GHG emissions in 2020.
• Reducing methane emissions from agriculture offers direct health benefits by lowering tropospheric ozone and reducing the inhalation of black carbon and volatile organic compounds (VOCs) like benzene and formaldehyde produced during crop burning.
• Dietary shifts toward plant-rich diets in high-income regions can reduce methane emissions and lower the risk of cardiovascular disease, diabetes, and obesity. A comparison in the UK, Germany, US, Netherlands, and Japan showed a 29% reduction in ischemic heart disease mortality for vegetarians.
• In the United States, voluntary technology-based reductions are insufficient; if all technically viable mitigation measures (excluding diet change) were adopted, livestock emissions could be reduced by 30%, saving an estimated 56 MtCO2e annually.
• In Vietnam, the adoption of Alternate Wetting and Drying (AWD) techniques for rice could reduce methane emissions by up to 48% and irrigation water use by 30% without sacrificing crop yield.
• Sustainable soil management practices could increase nutrient-rich soils by 58%, which is critical as agricultural production must increase by 60% by 2050 to feed the growing population.
• Global agricultural subsidies are estimated at nearly $630 billion annually, primarily supporting rice, sugar, and meat, which creates disincentives for the production of fruits and vegetables.
