Nature-based solutions that protect ecosystems avoid emissions associated with ecosystem degradation and preserve carbon stored underground. But they can also do so much more. Wetlands, for instance, also provide a buffer from waves and storm surge, protecting coastal communities from the effects of extreme weather events. One analysis found that wetlands in the northeastern United States avoided US$625 million in flood damages during Hurricane Sandy.
Similarly, forests can regulate local climate and weather patterns and can reduce daytime temperature extremes. One study found that, on average, daytime temperatures were 4.1ºC (~7°F) cooler inside forests than in nearby ecosystems with less forest cover. Other ecosystems, such as peatlands and grasslands, can provide flood protection to nearby communities during periods of excessive rain.
On the mitigation side, these nature-based solutions provide immediate climate mitigation benefits. The protection of forests, wetlands, peatlands, and grasslands is an emergency brake climate solution, meaning it works quickly to reduce greenhouse gases in the atmosphere and prevent large pulses of carbon dioxide caused by the clearing of these landscapes. This fast-acting mitigation potential, combined with their adaptive benefits, means these solutions should be foundational for climate action in the places where they can be implemented.
Decades of insufficient climate action have narrowed each pathway, that toward mitigation and toward adaptation. To make up for that lost time, those of us working in climate must prioritize solutions that allow us to walk both paths simultaneously. Communities need solutions that reduce emissions while also protecting human well-being, livelihoods, and economies, today and into the future. Climate mitigation does not need to come at the cost of climate adaptation. We have solutions that can deliver meaningful adaptation benefits alongside emissions reductions. By focusing on solutions that do both, the pathway toward a safe, prosperous future becomes wider for us all.
