The economic costs of planting, preserving, and managing the world’s forests to mitigate climate change

Austin et al. 2020

It is now well established that forest protection, restoration, management and creation play a crucial role in mitigating climate change. This paper estimates the costs of such actions, and the amount of forest-based climate change mitigation that could be funded by different carbon prices. They find that a carbon price of $281 [...] Read more December 10, 2020

Anthropogenic modification of forests means only 40% of remaining forests have high ecosystem integrity

Grantham et al. 2020

The effects of human activities on forests goes beyond deforestation – forests that are still standing are often disturbed by humans as well. This study generated a global map of forest condition, using an index of forest integrity on a continuous scale from 0 to 1. The forest integrity index acts as [...] Read more December 10, 2020

Climate reverses directionality in the richness–abundance relationship across the World’s main forest biomes

Madrigal-González et al. 2020

It is critical that forest restoration is informed by the best possible science, to maximise carbon storage and other benefits over the long term. There are two competing hypotheses about whether the number of tree species or tree abundance is more important for maximising forest carbon storage. This study tested these hypotheses [...] Read more November 30, 2020

The greenhouse gas offset potential from seagrass restoration

Oreska et al. 2020

Seagrass meadows are highly productive systems that bury organic carbon in sediment. This study is the first to quantify net greenhouse gas removal from the atmosphere from seagrass restoration. The authors measured all the necessary greenhouse gas parameters in the 7km2 of restored eelgrass meadow in Virginia, USA, finding that the restoration [...] Read more November 30, 2020

Strengthening synergies: how action to achieve post-2020 global biodiversity conservation targets can contribute to mitigating climate change

De Lamo et al. 2020

This report looks at how much climate change mitigation would be achieved if we meet biodiversity conservation targets. It is the first output of ongoing research on this topic, and uses information on carbon stocks in locations that have been identified as priorities for meeting biodiversity targets. The report finds that [...] Read more November 30, 2020

Global priority areas for ecosystem restoration

Strassburg et al. 2020

It is of critical importance that multiple different outcomes of ecosystem restoration are considered when deciding where and how to restore; failure to do so can lead to detrimental trade-offs between outcomes. This study assessed the effects of ecosystem restoration on both biodiversity conservation and carbon sequestration, quantifying how this varies at [...] Read more October 14, 2020

Mapping carbon accumulation potential from global natural forest regrowth

Cook-Patton et al. 2020

Estimating how much carbon is taken up by growing forests, and what the global climate change mitigation potential of reforestation is, has been a topic of much debate for the last few years. This study provides the latest estimate of carbon accumulation over the first 30 years of regrowth of natural [...] Read more September 23, 2020

Economic and social constraints on reforestation for climate mitigation in Southeast Asia

Zeng et al. 2020

Reforestation will play an important role in mitigating climate change, but some estimates of reforestation potential lack consideration of social and economic constraints. This paper takes the example of Southeast Asia to estimate the extent to which such constraints reduce total mitigation potential from reforestation. 121 million ha of land were identified [...] Read more August 25, 2020

Local People’s Participation in Mangrove Restoration Projects and Impacts on Social Capital and Livelihood: A Case Study in the Philippines

Valenzuela et al. 2020

Participatory management of mangrove restoration projects by local People’s Organisations in two communities in Quezon, Philippines, has been shown to provide substantial benefits for the people involved as well as increasing long-term sustainability of the restoration projects themselves. Members of People’s Organisations increased their social capital by gaining more numerous and more [...] Read more August 24, 2020

Climate change mitigation potential of wetlands and the cost-effectiveness of their restoration

Taillardat et al. 2020

Although inland and coastal wetlands are highly efficient sinks of carbon dioxide, they also release methane – another carbon-containing greenhouse gas. Hence, wetlands can in some cases draw down carbon and yet have a net warming effect on the climate due to methane release. This means that restoration, protection and management of [...] Read more August 24, 2020
