Natural Regeneration

Natural forest regeneration is the most cost-effective nature-based solution as it is a low-cost, low-tech and high impact strategy for restoring forests, sequestering carbon, and conserving biodiversity

Harnessing the power of nature is essential for achieving the Paris Agreement goal of limiting global warming to well below 2°C beyond pre-industrial levels. Nature-based solutions can provide 30% or more of the climate change mitigation needed by 2030, yet they receive only 2% of global climate funding. Current nationally determined contributions to the Paris Agreement do not reflect the full potential of nature.

The most cost-effective solution for removing carbon from the atmosphere is restoring forests, and the most cost-effective way of restoring forests is by removing barriers to the natural regeneration process and—where required—accelerating it, a strategy known as assisted natural regeneration.

Under suitable conditions, assisted natural regeneration can reduce the costs of implementing restoration by more than 70% compared to active restoration, which uses full tree planting. Natural regeneration requires little or no specialist training.

Active restoration strategies can be used in areas where:
> economic development using timber species and agroforestry strategies are required by local communities; or
> assisted natural regeneration is not ecologically or economically feasible – that is, areas where land degradation or the opportunity cost of land is high, and the land is far from forest remnants from which seeds would naturally disperse.

Assisted natural forest regeneration can be used to help countries meet their nationally determined contributions to the Paris Agreement, post-2020 targets under the UN Convention on Biological Diversity, and Land Degradation Neutrality targets
