The number of tree coverage on farms is on the rise, and a recent study published in the journal Scientific Reports has added this hidden cache of carbon storage to the global carbon count. Researchers found out that farms sequester four times as much carbon as current estimates indicate, using remote sensing and a land cover database.
Researchers found that 43 percent of farmland across the globe had at least ten percent tree cover in 2010. Including the carbon sequestering capacity of this tree cover increased storage capacity estimates for farmland from 11.1 gigatonnes of carbon to 45.3 GtC. At least 34 GtCs of this storage capacity is from trees. They also found that between 2000 and 2010, tree cover on farms increased by two percent. This resulted in a 2GtC, or 4.6 percent, increase in biomass carbon.
Probably fewer than half the contributors and readers of this blog are vegetarian, with a tiny percentage perhaps being vegan. A new study from Oxford University published in the Proceedings of the National Academy of Sciences of the United States might set some of us thinking about changing that, however.
With food in general creating over 25% of all global greenhouse gas emissions (including the need for transportation and all the rest), to think that about 80% of those emissions are linked to livestock makes one realize (once again, if we didn’t already know) the massive impact of eating red meat. Sarah DeWeerdt reports for Conservation magazine’s online section:
If every person on Earth adopted a vegan diet – without milk, meat, honey, or any other animal-sourced foods – the greenhouse gas emissions associated with the food system in 2050 would fall by more than half compared to 2005/2007 levels. That’s one of several striking findings from an analysis of food and climate published yesterday in the Proceedings of the National Academy of Sciences.
