FOREST INK: Develop a national strategy to salvage wood burned in wildfires

"...As he points out this could be a window of opportunity to consider other options to mill closures but it will be a short-term supply of cheap wood. He then goes on to discuss the longer-term changes that need to take place to deal with the increasing wildfire season. It is time to talk about developing reforestation plans where harvested mixed-wood stands are returned to mixed-wood forests instead of being converted to softwood mono cultures..."

FOREST INK: Carbon-neutral agriculture an option

"...Biochar is described as the New Black in reference to the importance of fossil fuels in industrial agriculture and the ongoing need to become carbon neutral. Management methods alone will not pave the way for climate-neutral food production. More research is needed, and pyrolysis of straw into biochar could prove to be part of the solution since it has the potential to reduce greenhouse gas emissions and at the same time increase the soil’s organic carbon content..."

Groups criticize CRD's pace in advancing thermal biosolid-disposal facility

"...Pictured is the Capital Regional District’s wastewater treatment facility at McLoughlin Point. Local groups have reiterated their opposition to land applying biosolids in the CRD as a long-term plan. (CRD image)..."

FOREST INK: North America’s largest biochar plant will be built in Quebec

"...The project will sequester 75,000 tons of carbon per year — equivalent to over 400 rail cars worth of burned coal — and generate certified carbon credits that will be sold by First Climate AG. Used as a soil amendment, biochar offers several benefits, including carbon sequestration, increased nutrient retention, and optimized soil aeration and drainage. Its properties allow it to contribute to soil regeneration, limit the use of fertilizers and sustain water resources..."

FOREST INK: Company invests $10M in biochar

"...There are also portable systems that could treat the residual logging cull piles that may not be economical to chip and bring to town for the energy plant and wood pellet manufacturing. As with many new ventures it is a matter of developing markets for a product so investors will be encouraged to support the system..."

Elon Musk's Carbon Removal XPrize dishes out $1M milestone awards

"...An unprecedented XPrize competition designed to develop solutions to the mounting levels of carbon dioxide in the atmosphere has progressed to its next phase, with 15 teams from around the world each awarded US$1 million to continue developing their technologies. Teams working on ultra-thin CO2-soaking membranes and techniques that bury plant matter in the ground are among those to earn recognition from the judges, and will now press ahead with efforts to massively scale up their approaches. Launched last February, the $100-million Carbon Removal XPrize is the richest XPrize competition ever conducted, and tasks competing teams with demonstrating how carbon can be captured from the air and safely stored away for at least 100 years..."

RANCH MUSINGS: Agriculture in the latest UN climate report

"...“The largest share of this economic potential comes from the conservation, improved management, and restoration of forests and other ecosystems (coastal wetlands, peatlands, savannahs and grasslands), with reduced deforestation in tropical regions having the highest total mitigation. Improved and sustainable crop and livestock management, and carbon sequestration in agriculture, the latter includes soil carbon management in croplands and grasslands, agroforestry and biochar ..."
