New York Times: How Big Forests Solve Global Problems

"How will we pay for a future with forest wilderness? Part of the answer lies in programs to avert climate change. A recent economic study indicates that a large share of intact forests could be preserved at a cost of $20 per ton of carbon. That’s less than half of one indicative benchmark figure: the $52 midpoint price projected by California for its regulated carbon emissions market in 2030."

Oliveira Garcia, Wagner de; et al. (2018): Increasing biomass demand enlarges negative forest nutrient budget areas in wood export regions

Oliveira Garcia, Wagner de; Amann, Thorben; Hartmann, Jens (2018): Increasing biomass demand enlarges negative forest nutrient budget areas in wood export regions. In Scientific reports 8 (1), p. 5280. DOI: 10.1038/s41598-018-22728-5.

"Energy production from biomass is one of the adopted strategies in different European countries to limit global warming to within the 1.5–2° targets after the 2015 UN climate agreement. This will motivate enhanced forest harvest rates and whole tree harvest to supply the increasing biomass demand. Negative nutrient budgets for certain timberland areas where geogenic nutrient supply cannot cope with harvesting rates will be one consequence. A spatially explicit analysis for a U.S. timberland area of 33,570 km2 reveals that for a minimum nutrient loss and supply scenario, negative nutrient budgets occur in 17, 20, 16, and almost 94% of the studied areas for Ca, K, Mg, and P, respectively."

VN Valley News: A Renewed Focus on Forestry

"Out of Cobb Hill Co-housing's 270 acres, 180 are forested, and as a member of the cooperative's forestry committee, Bill Stack helps manage the woods with the goal of improving its health and diversity. Part of that management includes preserving and encouraging the growth of larger trees that hold more carbon."

EcoWatch: One Million Trees Pledged to 'Trump Forest' to Offset President's Anti-Climate Agenda

"Trump Forest—a global reforestation project aiming to offset President Trump's anti-climate policies—has reached 1 million trees after thousands of pledges from around the world. Trump Forest was launched just under a year ago after POTUS announced he was pulling the U.S. from the Paris agreement."

Yosef, Gil; et al. (2018): Large-scale semi-arid afforestation can enhance precipitation and carbon sequestration potential

Yosef, Gil; Walko, Robert; Avisar, Roni; Tatarinov, Fedor; Rotenberg, Eyal; Yakir, Dan (2018): Large-scale semi-arid afforestation can enhance precipitation and carbon sequestration potential. In Scientific reports 8 (1), p. 996. DOI: 10.1038/s41598-018-19265-6.

"Here, we use a Global Climate Model to provide a process-based demonstration that implementing measured characteristics of a successful semi-arid afforestation system (2000 ha, ~300 mm mean annual precipitation) over large areas (~200 million ha) of similar precipitation levels in the Sahel and North Australia leads to the weakening and shifting of regional low-level jets, enhancing moisture penetration and precipitation (+0.8 ± 0.1 mm d−1 over the Sahel and +0.4 ± 0.1 mm d−1 over North Australia), influencing areas larger than the original afforestation. "

Sonntag, Sebastian; et al. (2018): Quantifying and comparing effects of climate engineering methods on the Earth system

Sonntag, Sebastian; González, Miriam Ferrer; Ilyina, Tatiana; Kracher, Daniela; Nabel, Julia E. M. S.; Niemeier, Ulrike et al. (2018): Quantifying and comparing effects of climate engineering methods on the Earth system. In Earth's Future. DOI: 10.1002/2017EF000620.

"To contribute to a quantitative comparison of climate engineering (CE) methods, we assess atmosphere-, ocean-, and land-based CE measures with respect to Earth system effects consistently within one comprehensive model. We use the Max Planck Institute Earth System Model (MPI-ESM) with prognostic carbon cycle to compare solar radiation management (SRM) by stratospheric sulfur injection and two carbon dioxide removal methods: afforestation and ocean alkalinization. The CE model experiments are designed to offset the effect of fossil-fuel burning on global mean surface air temperature under the RCP8.5 scenario to follow or get closer to the RCP4.5 scenario."

Triple Pundit: Planting Trees Has Become a Big Business

"Nevertheless, there are companies finding success in this sector. One of them is United Kingdom-based Biocarbon Engineering, which operates a fleet of drones reforesting areas that are difficult to access. The Dutch firm Land Life Company, maker of water vessels based on an ancient Mesopotamian technology, manages ongoing projects from Chile to Zambia and expects to be profitable in a few years. Land Life claims its “cocoons,” made out recycled wood pulp, offer a much higher survival rate for tree seedlings compared to traditional tree planting methods."

Stop GE Trees: Report: Large-scale Biosequestration Causing Negative Social and Environmental Impacts

"At the start of a major Climate Engineering Conference in Berlin, the Global Forest Coalition has launched a Working Paper that highlights the risks of different proposals for large-scale Carbon Dioxide Removal. The report finds that while the most prominent CDR approach, Bioenergy and Carbon Capture and Storage (BECCS) technology is still in a state of “infancy” and is unlikely to be rolled out on a global scale, biosequestration in the form of afforestation through monoculture tree plantations is already rapidly expanding and causing significant negative social and environmental impacts."
