\n\t

At the start of this new decade, and in the midst of an avalanche of bad news \u2013 including the catastrophic mega bushfires in Australia \u2013 we can take hope from the fact that nature-based solutions are finally getting more recognition for their important role in the fight against climate change.<\/p>\n<\/div>\n<\/div><\/div>

\n
\n\t

We are quickly running out of time on climate change and biodiversity. It is critical that we prioritise the most useful nature-based solutions: protecting the planet\u2019s remaining primary forests and intact forest landscapes.<\/p>\n<\/div>\n<\/div><\/div><\/div>

\n
\n\t

This is a positive development, but whether it will result in real progress is still unclear. The effectiveness of nature-based solutions varies a lot, and choosing the right solution makes a world of difference. This is especially true in the case of forests. Many of the nature-based solutions to climate change being proposed today simply entail mass tree planting schemes. These initiatives may sound appealing but are in fact costly, largely irrelevant to addressing the climate and biodiversity crises, or worse, counterproductive.<\/p>\n

We are quickly running out of time on climate change and biodiversity. It is critical that we prioritise the most useful nature-based solutions:\u00a0<\/em>protecting the planet\u2019s remaining primary forests and intact forest landscapes.<\/p>\n<\/div>\n<\/div><\/div>

Keep the carbon where it is<\/h2>\n
\n\t

Nature-based solutions are defined by IUCN as \u201cactions to protect, sustainably manage, and restore natural or modified ecosystems that address societal challenges effectively and adaptively, simultaneously providing human well-being and biodiversity benefits\u201d. To understand which nature-based solutions we should prioritise, we need to think like doctors: our planet is running a fever, so our first directive is to \u2018treat the cause, not just the symptoms\u2019. This means doing everything possible to avoid further carbon dioxide emissions and making global warming worse.<\/p>\n<\/div>\n<\/div><\/div>

\n
\n\t

The Amazon forest alone stores so much carbon that if it were all released through deforestation, global warming would exceed the 1.5\u00b0C threshold, even if we stopped using fossil fuels.<\/p>\n<\/div>\n<\/div><\/div><\/div>

\n
\n\t

Forests and other ecosystems store vast amounts of carbon. There is more carbon in forest ecosystems \u2013 in the living and dead biomass of trees and in soils \u2013 than there is currently in the atmosphere, and in fact more than in all known oil and coal reserves\u00a0combined<\/em>. The Amazon forest alone stores so much carbon that if it were all released through deforestation, global warming would exceed the 1.5\u00b0C threshold, even if we stopped using fossil fuels.<\/p>\n

Preventing carbon emissions from degradation and deforestation is therefore as necessary for mitigating climate change as reducing fossil fuel emissions. Given the climate emergency, it is crucial to keep those enormous carbon stocks exactly where they are \u2013 safely stored in forests and out of the atmosphere.<\/p>\n<\/div>\n<\/div><\/div>

But that's not the whole story<\/h2>\n
\n\t

Primary forests \u2013 naturally evolved forests that have not been disturbed by industrial activity and retain their native biodiversity \u2013 store about 30-50% more carbon than degraded forests, including forests managed for commodity production. Their carbon stocks are also more stable and resilient than those of degraded forests or plantations because their biodiversity and ecosystem integrity make them more resistant to external pressures. Tropical primary forests, for example, are more resistant to fire, drought and invasive species than degraded tropical forests and plantations. This is a crucial point, and too often overlooked in forest policies and programmes. The native biodiversity and unique structure and composition of a primary forest, which has evolved over millennia (or longer), allows primary forests to\u00a0maximise<\/em>\u00a0carbon stocks and keep those carbon stocks safe for the long-term.<\/p>\n

In other words, climate change mitigation, biodiversity and ecosystem integrity are inextricably linked, and primary forests are a fundamental point of convergence \u2013 a place where biodiversity and climate mitigation values are greatest. This is what makes primary forests and other primary ecosystems truly irreplaceable. The biodiversity and carbon stored in primary forests are quickly lost but slow to recover.<\/p>\n<\/div>\n<\/div><\/div>

Protect first, the restore<\/h2>\n
\n\t

If the top priority nature-based solution for climate change is to protect primary forests and their biodiversity, the next order of priority is ecological restoration of degraded forests, also known as proforestation. This allows degraded forests to begin to regain their primary forest values over time.<\/p>\n<\/div>\n<\/div><\/div>

\n
\n\t

Plantations store far less carbon than natural forests, protect far less biodiversity and are more vulnerable to disturbance, so their carbon stocks are far less secure.<\/p>\n<\/div>\n<\/div><\/div><\/div>

\n
\n\t

Following proforestation, the next restoration objective should be to regenerate forests naturally where they have been cleared. Forests often regenerate most easily next to primary forest patches because even small remnants of primary forests serve a vital function as seed banks, and as habitat for seed dispersers. Focusing restoration efforts around these primary forests remnants is critically important to landscape restoration efforts. In some cases, ecological restoration cannot occur without active intervention because the land is too degraded. But this is expensive, and seed dispersers such as birds or monkeys replant forests better than humans. Allowing the forest to come back on its own is preferable where it is still possible.<\/p>\n

On the other hand, tree planting schemes and large-scale plantations should be recognised as the\u00a0lowest<\/em>\u00a0priority for climate mitigation and biodiversity. Seedlings planted today will not accumulate large amounts of carbon in the next decades \u2013 that is, the relevant time frame for staying below 1.5\u00b0C of warming. A degraded forest recovering from disturbance will drawdown much more. In addition, plantations store far less carbon than natural forests, protect far less biodiversity and are more vulnerable to disturbance, so their carbon stocks are far less secure. Because plantations are harvested on a regular basis, they also regularly release all or part of their carbon into the atmosphere.<\/p>\n

This is not to say that plantations can\u2019t be useful: assuming they do not displace local communities, food production or ecological restoration efforts, and their environmental impacts are mitigated, plantations can help meet wood demand and reduce pressure on natural forests. However, they are at best a marginal mitigation strategy.<\/p>\n<\/div>\n<\/div><\/div>

Primary forests are irreplaceable<\/h2>\n
\n\t

Primary forests are often the customary homelands of Indigenous Peoples, they are essential to protecting cultural and linguistic diversity, and they are fundamentally important to the livelihoods of local communities. They also provide a wide range of ecosystem services: they protect the most carbon and biodiversity, produce the cleanest freshwater, regulate water flows, have local cooling effects and prevent erosion. And yet they are disappearing very fast. We lose millions of hectares of primary forest every year. We have lost a third of the planet\u2019s forest cover already, and less than a third of what remains is primary forest.<\/p>\n

The message is simple. We are facing accelerating and interrelated biodiversity and climate change crises. We cannot resolve either crisis without prioritising the protection of primary forests and engaging in large-scale ecological restoration. This is critical to human well-being, to the diversity of life on Earth, and for a climate-safe future.<\/p>\n<\/div>\n<\/div><\/div>

\n
\n\t

We know how to protect and restore ecosystem integrity: it requires empowering and supporting Indigenous Peoples and communities who are the traditional owners and stewards of these forests, and scaling up protected areas of all governance types, payments for ecosystem services, forest ecosystem connectivity conservation initiatives, and other effective area-based conservation measures.<\/p>\n

This will in turn require shifting funding from subsidies that fuel forest degradation and destruction to conservation \u2013 as well as greatly increasing the two percent of climate funding currently allocated to forests and prioritising it appropriately, to support the highest impact climate mitigation actions: primary forest protection, proforestation and ecological restoration.<\/p>\n<\/div>\n<\/div><\/div>

Making primary forests a priority<\/h2>\n
\n\t

In recognition of the crucial importance of primary forests, IUCN Members overwhelmingly approved a\u00a0resolution<\/a>\u00a0at IUCN\u2019s Jeju World Conservation Congress in 2012 to establish a working group to develop an IUCN policy on primary forests including intact forest landscapes. A\u00a0second resolution<\/a>\u00a0at the IUCN World Conservation Congress in Hawaii in 2016 continued this work, and following an extensive consultative process, the\u00a0final policy<\/a>\u00a0was approved by IUCN\u2019s Council in February 2020. Further promotion of the new policy will feature at the\u00a02020 IUCN World Conservation Congress<\/a>\u00a0in Marseille.<\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>
