An economist's view of forest landscape restoration | IUCN In 2011, after proving that Miyawakis method could work for his own experimental backyard forest, he quit his job at Toyota and opened a forest-production company named Afforestt, which practices what Miyawaki preaches: the introduction to a depleted landscape of potential natural vegetation, which is what would naturally occur in that particular place without human intervention. Large-scale reforestation has massive potential to stave off a climate collapse. ; Garrido, M.; Domini, C.E. more Oecologia. Gisi, S.D. ; software, Q.X. Research from Wageningen University in the Netherlands, which found increased fungi, bacteria, pollinators, and amphibians on two tiny planted forest sites in urban Zaanstad that were based on Sharmas models,, lends some scientific credence to this claim. As for dredged sediment, most remediation methods are basically increasing the mobilization or immobilization of metals to reduce toxicity and bioavailability. ; Murray, C.A. It also found that tearing down the rainforest would have significant impacts on economies long term by decreasing rainfall and could cost a staggering $422 million in annual loss to agriculture.
