Cai et al. (2023): Spatial-temporal variation of the carbon sequestration rate of afforestation in China: Implications for carbon trade and planning

Weixiang Cai, Nianpeng He, Li Xu, Mingxu Li, Ding Wen, Shirong Liu, Osbert Jianxin Sun IN: Science of The Total Environment 884, 163792,

The lack of hierarchical spatial-temporal maps for the carbon sequestration rate (CSR) from afforestation and reforestation at the national scale impedes the scientific implementation of forest management planning to a large extent. The authors assessed the spatial-temporal CSR per area for afforestation and reforestation at the provincial, prefectural, and county levels in China using a forest carbon sequestration model under three climate scenarios. 


Nature – Merk et al. (2023): German citizens’ preference for domestic carbon dioxide removal by afforestation is incompatible with national removal potential

Christine Merk, Ulf Liebe, Jürgen Meyerhoff, Katrin Rehdanz IN: Commun Earth Environ 4, 100

Proposed removal methods result in trade-offs with other Sustainable Development Goals, and the removal needs of many countries exceed their domestic potentials. The authors examine the public acceptability of conducting afforestation and direct air capture programmes domestically in Germany or abroad. To uncover the relative importance of various programme attributes, the authors use a multifactorial vignette experiment. They find that afforestation receives stronger support than direct capture.


Nature – Caldera & Breyer (2023): Afforesting arid land with renewable electricity and desalination to mitigate climate change

Upeksha Caldera & Christian Breyer IN: Nat Sustain (2023).

In this research, existing concepts of low-cost renewable electricity (RE) and seawater desalination are built upon to identify the global CO2 sequestration potential if RE-powered desalination plants were used to irrigate forests on arid land over the period 2030–2100. The results suggest a key role for afforestation projects irrigated with RE-based desalination within the climate change mitigation portfolio.


Nature- Rohatyn et al. (2023): Large variations in afforestation-related climate cooling and warming effects across short distances

Shani Rohatyn, Eyal Rotenberg, Fyodor Tatarinov, Yohay Carmel, Dan Yakir IN: Commun Earth Environ 4, 18;

The authors show in a four-year study that the biogeochemical vs. biogeophysical balance in paired forested and non-forested ecosystems across short distances (approximately 200 Km) and steep aridity gradient (aridity index 0.64 to 0.18) can change dramatically. The required time for the forestation cooling effects via carbon sequestration, to surpass warming effects associated with the forests’ reduced albedo and suppressed longwave radiation, decreased from 213 years in the driest sites to 73 years in the intermediate and 43 years in the wettest sites.


Betting on Forests and Soils to Reach Net-Zero

January 19th, 2023; 1:00 pm – 2:00 pm EST

Join the Institute for Carbon Removal and Policy for the next event in its webinar series Scrubbing the Skies: The Role of Carbon Dioxide Removal in Combating Climate Change. This series will focus on scientific, technological, legal, political, and justice-focused issues associated with carbon dioxide removal. The host for the series will be Wil Burns, Visiting Professor in the Environmental Policy & Culture Program at Northwestern University. The fourth webinar in this series is: „Betting on Forests and Soils to Reach Net-Zero.“


Hong et al. (2023): Effects of Afforestation on Soil Carbon and Nitrogen Accumulation Depend on Initial Soil Nitrogen Status

Songbai Hong, Nan Cong, Jinzhi Ding, Shilong Piao, Lingli Liu, Josep Peñuelas, Anping Chen, Timothy A. Quine, Hui Zeng, Benjamin Z. Houlton IN: AGU Global Biochemical Cycles 37 (1);

In this study, the authors conducted an intensive field sampling investigation including 610 pairs of afforested and control plots in northern China and extensively compiled a global data set containing 211 afforested-control pairs worldwide to evaluate responses of soil N concentrations and C:N ratios to afforestation and further explored their major regulator.


Masisi et al. (2022): Fighting climate change with bamboo in Africa: The case of Kyela, Rungwe and Mufindi districts – Tanzania

Bhoke Masisi, Astrid Zabel, Jürgen Blaser, Suzana Augustino IN: Advances in Bamboo Science 1, 100009,

Taking Tanzania as an example, the authors lay a special focus on bamboo carbon sequestration and storage potential and assess the dynamics of carbon stocks: (i) across an elevation gradient, (ii) between indigenous and exotic bamboo species, and (iii) between intensively and extensively managed bamboo ecosystems. The authors collected data from 60 destructive sample plots and estimated biomass carbon stocks in the aboveground carbon pool.


Jayakrishnan & Bala [Preprint]: A comparison of the climate and carbon cycle effects of carbon removal by Afforestation and an equivalent reduction in Fossil fuel emissions

Koramanghat Unnikrishnan Jayakrishnan & Govindasamy Bala IN: Biogeosciences Discuss. [preprint],, in review, 2022.

In this paper, the authors compare the climate and carbon cycle consequences of carbon removal by afforestation and an equivalent fossil fuel emission reduction using simulations from an intermediate complexity Earth system model. The author’s simulations show that the climate is cooler by 0.36 °C, 0.47 °C, and 0.42 °C in the long term (2471–2500) in the case of reduced fossil fuel emissions compared to the case with afforestation when the emissions follow the SSP2-4.5, SSP3-7.0, and SSP5-8.5 scenarios, respectively.


The Land Gap Report

This Land Gap Report shows how countries’ climate plans, if implemented, will increase the aggregate demands made on land. The report quantifies the aggregate demand for land and land-use change to address climate mitigation in the climate pledges submitted by Parties to the UNFCCC. A key finding is that countries’ climate pledges assume that almost 1.2 billion hectares of land can be prioritized for carbon dioxide removal. An international team analyzed commitments made for years 2030, 2050, and 2060 — looking at individual pledges and the implications for land use.
