According to a report published Friday by Agencia Brasil, a group of scientists from that country has found new techniques which could be of use in forest recovery and increase the capture of carbon from the atmosphere.
The study began in the Amazon Forest, with soil analysis in Serra de Carajás, an area where Vale operates, mainly in the rusty rupestrian fields and in the Carajás National Forest.
“The capacity of forest agrosystems is evaluated, which are more conservative systems that use the planting of fruit trees, associated with tree species.
In the same way, we can compare different cropping systems, different plantings, and indicate which system is contributing to overall soil improvement and which is degrading it,” Valadares elaborated.
But also as carbon sequestration, water purification – the water that comes out of the spring is usually clean because the soil performs this purification; degradation of contaminants – many of which end up in the soil, the microbiota itself degrades these contaminants,” he explained.
When the soil is degraded, it becomes compacted and cannot store this rainwater, which ends up going all the way to the rivers, and then the great floods that we see today happen.
“We have exponential growth of the world population and the amount of degraded soils is increasing a lot.
“The climate change issue, which is related to the low carbon economy, initially had the idea of reducing the emission of CO2 into the atmosphere and today we work with two areas related to this: to reduce the emission, to sequester, to drain the carbon that is in the atmosphere.
In Brazil, the issue has been discussed in the House of Representatives with the PL 528/2021, which creates the Brazilian Market for Emissions Reduction .
