Environment enthusiast and researchers all over the world are trying to find a potent solution to the Global Warming, meanwhile ,a new study suggests that Earth’s soil can help in reducing the levels of greenhouse gases that are the major source of global average temperature rise.
According to estimates, Earth’s soil can absorb extra 8 billion tonnes of greenhouse gas than previously thought, and it is enough to bring down the rising temperature as gases like carbon dioxide are the major contributors to the heating of Earth’s atmosphere.
The feat can be achieved by sustainable land use with a global maintenance plan involving the use of latest technology. Scientists believe that unleashing the power of tech and proper land use can help farmland and other spaces like forests to store more greenhouse gases that are emitted into our atmosphere.
Scientists from the Universities of Aberdeen and Edinburgh in the UK, estimated that around four-fifth of annual emissions released by the burning of fossils fuels can be curbed just by growing crops with deeper root systems, using charcoal-based composts and implementing sustainable agricultural method that will enable Earth’s soil to absorb more amount of greenhouse gases.
Soil has this amazing capability to absorb the greenhouse gases in the past too, but no scientist ever noticed it due to lack of monitoring tools and poor technological equipment. As the technology advanced, it enabled researchers to identify the potential of soil. According to study authors, sustainable soil management will benefit humans by curbing the global warming.
While releasing the data in public, scientists said that presently Earth’s soil contains around 2.4 trillion tonnes of greenhouse gases that are locked in as an organic matter and scientists believe that with the proper implementation, the soil can hold extra 8 billion tonnes of greenhouse gases.
“Soils are already huge stores of carbon, and improved management can make them even bigger,” said Dave Reay from the University of Edinburgh. “With the surge in availability of ‘big data’ on soils around the world, alongside rapid improvements in understanding and modelling, the time has come for this big-hitter to enter the ring,” said Reay. “It is difficult to easily measure changes in soil carbon as changes are slow and we are trying to measure a small change against a large background,” said Pete Smith from the University of Aberdeen.
