But climate change isn’t simply a function of how much greenhouse gases we emit; it depends on how we damage the things that take up carbon. Of course, reforestation isn’t as easy as that - which we’ll touch on below - but the idea remains a simple one. Robin Chazdon, a forest ecologist and an emeritus professor at the University of Connecticut, wanted to figure out which restored forests would deliver the most net benefits to humanity. So the biggest hurdle may be coming up with an economic system that benefits the environment while protecting the most vulnerable. Ron Johnson turned the Senate into a platform for discredited election conspiracy theories. Climate change-exacerbated weather extremes like torrential downpours can also damage forests. Dark leaves on trees can cause local temperatures to rise. SINGAPORE - Reforestation has been touted as a relatively quick and easy fix for dealing with climate change, with plans afoot both in Singapore … That’s two-thirds of the roughly 300 billion metric tons of carbon humans have put up there since the dawn of the Industrial Revolution. While some regions may become less hospitable to trees, others may benefit from increasing carbon dioxide in the atmosphere, so extrapolating forest behavior from the present into the future may not make sense. This returns some of the carbon back to the sky and leaves some carbon in the ground. tion and reforestation in climate change mitigation have been widely discussed. Expand the use of forest products that sustainably replace fossil-fuel emissions Crowther hinted at these findings earlier this year and noted that this would amount to growing 1.2 trillion new trees across the planet. “To really make this work economically kind of requires a frameshift in the way we generate economies,” Chazdon said. TR can also play other frequently overlooked, but significant, roles in helping society and ecosystems adapt to climate variability and change. Even if a government were inclined to restore a forest, there is a finite amount of money, resources, and political capital to do so. They found that tropical rainforests — in countries like Brazil, Indonesia, India, Colombia, and Madagascar — in particular stood out. Reforestation, climate change For the past six years, researchers at the Universitat Politènica de València (Polytechnic Univeristy of Valencia, … Reforestation can buy us time to cut our carbon emissions,” says Bastin. Discover how reforestation can impact climate change by decreasing carbon dioxide in the atmosphere. Still, supporting natural systems that can soak up carbon is widely accepted as a major component of any climate change mitigation strategy — in addition to deploying clean energy, switching to electric vehicles, and curbing consumption overall. As deforestation has ramped up, Earth’s climate has changed significantly. Another study out this week tries to offer more specific guidance on where we should be focusing reforestation efforts. They suggest a sequestration potential of 200 GtC, but (incorrectly) suggest it would represent two-thirds of all emissions from human activities so far. However, many of these hot spots are already being used in other ways, like for farming and livestock grazing. Chazdon and her team then identified restoration hot spots, regions that scored in the top 10 percent in their evaluation. Reforestation has been getting a lot of attention lately, with some touting it as the #1 climate change solution, and others worrying that it's taking the spotlight away from other sustainability priorities. Main causes of climate change could likely be attributed to greenhouse effect, changes in land cover and solar radiations, but also to human activities (Orazio et al. “We did find some concentrations of these highest scores were distributed all over the tropics.”. In many tropical regions where large areas of forest have historically been cleared for agriculture, reforestation, including natural regeneration, assisted restoration, enrichment planting, native tree plantations, commercial plantations, and agroforestry systems, is creating new opportunities and challenges in the context of climate change (Chazdon 2008). In 2005 and 2006 the Alberta Forest Genetic Resources Council conducted an in-depth review of genetic resource management issues related to climate change, drafted a framework document for climate change planning, and adopted the following statements of principle: In other words, climate change is a mixed bag for forests. ... tree planting and reforestation were included as activities eligible for finance under the Kyoto protocol. In a paper published on Wednesday in the journal Science Advances, Chazdon and her collaborators came up with a scoring system for the world’s forests to figure out where restoration would yield the greatest benefits. However, Laura Duncanson, an assistant professor and a forest researcher at the University of Maryland who was not involved in the study, said this estimate is simplistic and doesn’t take into account much of the regional variation that can influence a forest’s capacity to absorb carbon. newsletter. So, how do we grow a forest in a drought? Large-scale reforestation needs to occur almost immediately if it’s going to have an impact on the efforts to limit climate change to 1.5° or 2°C of warming. Earth Day Network’s Canopy Project plants trees to benefit local communities, increase habitat for species, and combat climate change. Forests play an important an important role in climate change. Tags EPA Environmental Protection Agency Environment carbon emissions Reforestation Forest Climate change Bioenergy Fossil fuels Clean Air Act . The situation is even more dire in the tropics, where less than half of forests remain standing today. Climate change-exacerbated weather extremes like torrential downpours can also damage forests. Click To Tweet “Natural climate solutions have really been a forgotten solution to climate change,” said Joe Fargione, the paper’s lead author and the head scientist for North America at The Nature Conservancy , a global conservation nonprofit. Perhaps the biggest difficulty with reforestation as a strategy is simply that it takes so much time to reap the benefits for global warming. The modern world’s insatiable appetite for wood, land, agriculture, and mineral extraction continues to drive deforestation. Forests are widely recognized as important carbon sinks, or ecosystems capable of capturing and storing large amounts of carbon dioxide, and can serve as a cost-effective strategy for mitigating greenhouse gas emissions. There is a distinction here between restoration, also known as reforestation, and afforestation. Crowther and his colleagues used global satellite images to assess tree canopies, figuring out where forests are and where they could reemerge. That absorption can change based on the species of tree, its size, its age, its location, the soil it’s growing in, and the climate around it. Reforestation also impacts climate change. Our analysis excluded reforestation in boreal regions since scientists question the climate benefits of reforestation in these regions.
