Regreening the planet could cut as much carbon as halting oil use – report
Natural solutions such as tree planting, protecting peatlands and better land management could account for 37% of all cuts needed by 2030, says A study published this year in Global Change Biology "An expert system model for mapping tropical wetlands and peatlands reveals South America as the largest contributor" estimates that tropical peatlands – the most important in terms of carbon storage – may cover three times more land than previously estimated.
But they are difficult to find because not all wetlands contain peat. The only way to know for sure is to send researchers to sample the soil, and that takes money.
Planting forests and other activities that harness the power of nature could play a major role in limiting global warming under the 2015 Paris agreement, an international study showed on Monday.
Natural climate solutions, also including protection of carbon-storing peatlands and better management of soils and grasslands, could account for 37% of all actions needed by 2030 under the 195-nation Paris plan, it said.
Combined, the suggested “regreening of the planet” would be equivalent to halting all burning of oil worldwide, it said.
“Better stewardship of the land could have a bigger role in fighting climate change than previously thought,” the international team of scientists said of findings published in the US journal Proceedings of the National Academy of Sciences.
The estimates for nature’s potential, led by planting forests, were up to 30% higher than those envisaged by a UN panel of climate scientists in a 2014 report, it said.
Overall, better management of nature could avert 11.3bn tonnes of carbon dioxide emissions a year by 2030, the study said, equivalent to China’s current carbon dioxide emissions from fossil fuel use.( The Guardian)
