I interviewed Australian Tim Flannery years ago. Here, 2019, and the carbon sequestering is still in the news. Carbon trading, carbon pricing? No way Jose.
Given the symbiotic relationship between soils and the vegetation they sustain, soil carbon loss happens all sorts of ways, deforestation being a prime example. We’re already losing about 18.7 million acres of forests per year. One international study finds that, under Brazil’s new president, Jair Bolsonaro, the deforestation rate of the Amazon could triple. At least 33 percent of global wetlands had been lost as of 2009, a recent paper suggests. A certain portion of the world’s grasslands has also been lost to desertification, which is when lands are stripped of their productivity due to things like drought and inappropriate farming methods (though there remain divided opinions as to the exact amount of grassland lost through human practices).
In the U.S., industrial farming practices like monocropping and routine tillage have led to the massive erosion of topsoil, where most of the carbon is stored. “Those practices are things that can be easily avoided,” said Roger Aines, chief scientist of the energy program at Lawrence Livermore National Laboratory. “When we’re dealing with sensitive soils, like in these wetlands and peat soils, you shouldn’t plow them or dig them up. When you’re dealing with soils that could blow away, you should keep a cover crop.”
That said, there is movement away from industrial agriculture toward regenerative farming methods, as evinced by the “4 per 1000” initiative launched by the French in the wake of the Paris Climate Conference in 2015. The overarching thrust of this initiative? That an increase by 0.4 percent a year in soil carbon content would “halt the increase in the CO2 concentration in the atmosphere related to human activities.” Same here in the U.S., where a farm in Northern California, for example, eschews plowing and weeding and all chemical or organic sprays in favor of a compost-intensive model. It apparently produces 10 times the average per-acre income of comparable California farms.read more here! One Solution to Climate Change No One Is Talking About!
