Wildfires in Brazil’s indigenous territory, 2017. Conservationists believe that restoration of the rainforest works best if a variety of seedlings are used, not just one kind.
I think humans are like ants in this regard: as soon as our anthill is destroyed, we start rebuilding. And as soon as greed destroys another swath of rainforest, conversationists, indigenous people, and fundraisers move in to rebuild. It may be hopeless, but that’s how we roll.
Bruno Vander Velde, managing director of content at Conservation International, writes at the Conversation about one rebuilding program.
“A bold initiative to regrow 73 million trees in the Brazilian Amazon has made substantial progress despite some unexpected hurdles, according to an upcoming report. While the global pandemic and an increase in Amazon fires presented setbacks, the initiative, launched in 2017, has delivered almost 20 percent of its forest restoration target, according to Conservation International in Brazil, one of several partners involved in implementation.
“The partners point to surprising progress taking root, as the COVID pandemic shows signs of leveling off and a new incoming presidential administration publicly commits to stem the tide of deforestation. …
“Launched at a Brazilian music festival, the initiative targeted areas along the southern edges of the Amazon forest, known as Brazil’s ‘arc of deforestation,’ as well as in the heart of the forest, where natural regeneration is still possible.
“By restoring these carbon-absorbing forests, the initiative is intended to help the South American country achieve its climate commitments under the Paris Agreement, as well as its target of reforesting 12 million hectares (nearly 30 million acres) of land by 2030.
“The initiative comprises two efforts: Amazonia Live, an effort led by the Rock in Rio music festival in collaboration with Conservation International and Brazilian nonprofit Instituto Socioambiental; and the Amazon Sustainable Landscape project, a collaboration among Conservation International, the Brazilian Ministry of Environment, the Global Environment Facility, the World Bank and the Brazilian Biodiversity Fund.
“In sum, the initiative is an experiment to ‘figure out how to do tropical restoration at scale, so that people can replicate it and we can drive the costs down dramatically,’ Conservation International CEO M. Sanjayan told Fast Company in 2017. …
“One of the initiative’s most noteworthy features was the use of a seed-planting method called ‘muvuca,’ widely advocated by the Instituto Socioambiental as a way to reduce restoration costs. Unlike typical reforestation efforts, in which tree saplings are planted one at a time, the muvuca method relies on spreading a large and varied mixture of native seeds across the targeted areas, to assure a higher diversity of trees. The technique’s results have exceeded expectations, experts say.
‘We’re seeing a tree yield that is three times higher than our initial estimates,’ said Miguel Moraes of Conservation International’s Brazil office.
“ ‘Rather than 3 million trees growing in 1,200 hectares (3,000 acres), as we would have expected, we’re estimating 9.6 million trees in the same area,’ based on monitoring reports, he added. …
“This restoration effort has not escaped some hard, real-world realities in Brazil’s Amazon. Some restored areas were burned by fires and will be monitored to see if they can regenerate on their own, Moraes said. (The area lost was not counted against the overall goal.)
“Such fires — all of them set by humans, usually to clear forests for agriculture and livestock — are a sign of the times. The Brazilian Amazon has been hit especially hard by wildfires in recent years. By September 2022, more forest fires were recorded in the region than in all of 2021, amid a surge of deforestation. …
“ ‘Our initial expectation [in this effort] was to prioritize the restoration of large contiguous areas within conserved areas,’ Moraes said. Restored forests in those areas should have been more durable; however, in the past two years ‘deforestation within protected areas in Brazil has increased significantly,’ he added.
“The resilience of the Brazilian Amazon’s many protected areas will be critical to the long-term success of the initiative.
“As it did around the world, COVID upended life in Brazil. …
“ ‘Like everyone, we were completely unprepared for a global pandemic — not only at the project level, but also at an individual level,’ [Moreas] said. … ‘Twenty percent restored might seem a low figure — and it generates a bit of frustration. But given the context, that we were able to achieve 20 percent of our target is impressive.’
“Even in the tropics, trees take years to grow to maturity. But reforestation projects usually last only a fraction of that time. … ‘Most projects like these are an intervention at a point of time, and then they end,’ Moraes said. ‘But restoration is a long and continuous process. So, ensuring permanence is a huge issue.’
“Practitioners are taking steps to address this, including planning for long-term satellite monitoring to keep a close eye on restored forests. They will also work with communities and local governments to try to bolster on-the-ground protection of these areas.
“Five years after the restoration initiative was announced, nearly three years into a pandemic and just weeks since a new administration took office in Brazil, project organizers are hopeful. The 2023 deadline for completion has been shifted to 2026, after some administrative challenges in the project’s early years. Organizers have now grown more comfortable managing the complexities inherent in a partnership of this size, Moraes said.
“ ‘I believe we underestimated the complexity of the challenge ahead of us. We are now trying to be more strategic. … Conservation International’s restoration efforts in Brazil go beyond just this effort,’ he said. ‘But if we succeed, we can show that we can make an impact at the scale needed to bring the forest back from the brink.’ ”
