Report Says “farming could be absorber of Carbon by 2050”.

Realizing the Paris Agreement goals could be possible through proper management of agricultural land in more sustainable manner like encouraging tree planting and improving soil fertility.

Below is the excerpt from the Journal on Nature Climate Change as The Guardian reports how Farming could be absorber of Carbon by 2050.

Tree-planting and improving the fertility of soil through better farming practices would also be needed, according to a study of global forests, farming and food systems published in the journal Nature Climate Change.

Managing agricultural and other land in a more environmentally sound manner could take the world nearly a third of the way towards meeting the Paris agreement goals. “These [measures] are feasible now and deliver many other benefits,” said Stephanie Roe, environmental scientist at the University of Virginia and lead author of the paper.

“Recent reports on the state of our forests and food systems show a worrying lack of progress in the land sector, and our window of opportunity to deliver on the Paris agreement is getting smaller. However, I remain optimistic because we have all the tools we need, as well as increasing public pressure and political will to turn things around.”

The changes would also allow for healthier diets globally, improve livelihoods in poor areas, preserve wildlife and flora, and make for higher water and air quality. Many of the measures suggested, such as cutting food waste and shifting from excessive meat consumption, would also save money. For example, improving soil management through organic farming practices would cost about $57bn (£43.9bn) but save nearly $2tn over the period, according to one estimate used in the study.

Land accounts for about 25% of global greenhouse gas emissions, or 11 gigatons of carbon dioxide a year. With the right measures, according to the study, it would act instead as a carbon sink absorbing 3 gigatons from the atmosphere a year by 2050. That could give some scope for other sectors such as aviation to continue to use limited amounts of fossil fuels while staying within the global carbon budget needed to avoid a temperature rise of more than 1.5C (a rise of 2.7F) above pre-industrial levels.

The authors set out a roadmap for the six large-scale measures they propose, including: reducing deforestation, peatland burning and mangrove destruction by 70%; restoring forests, peatlands and coastal mangroves to generate enough carbon dioxide saving to cancel out China’s annual emissions; planting trees to save as much carbon dioxide as that emitted by the EU.

Nancy Harris of the World Resources Institute, a co-author of the study, said: “The longer we delay action to protect forests, the more difficult it will be to achieve the Paris agreement targets and the more we will need to rely on unproven negative emission technologies.”
