Russian Forests And Climate Mitigation | Earth Wise

August 24, 2021 By EarthWise Leave a Comment

Russia is the largest country in area in the world, almost equal in size to the sum of the next two largest – Canada and the U.S. Russia is also the world’s largest forest country, containing more than one-fifth of the world’s forests. As a result, the country’s forests and forestry activities have enormous potential for impacting climate mitigation.

Since the dissolution of the USSR, there has been a decline in the availability of information on the state of Russia’s forests. The Soviet Forest Inventory and Planning System compiled information until 1988. Since then, the Russian National Forest Inventory has been the source of forest information on the national scale, and it hadn’t produced a comprehensive inventory until 2020.

The new data indicates that Russian forests have in fact accumulated a large amount of additional biomass over the intervening years. Using the last Soviet Union report as a reference point, the new results show that the ongoing stock accumulation rate in Russian forests over the 26-year period is of the same magnitude as the net forest stock losses in tropical countries.

Thus, it is clear that Russian forests have great potential in terms of global climate mitigation as well as potential co-benefits relating to the green economy and sustainable development. It is important to note that as the impact of climate change increases, disturbances to the Russian forests could have severe adverse effects on global climate mitigation efforts.

While much of the world’s attention is rightfully upon tropical rainforests in the Amazon and elsewhere, it is important to not ignore the largest country in the world hosting the largest land biome on the planet where even small percentage changes in the amount of forest biomass could have a major global impact.

Carbon Capture As Big Business

December 26, 2019 By EarthWise Leave a Comment

Removing greenhouse gasses from the atmosphere is an essential part of the overall effort to achieve zero net carbon emissions and stabilize the climate. Since we have not been able to reduce emissions fast enough to do the job, it is important to find ways to pull carbon dioxide out of the atmosphere.

There are many ways to do it, but they tend to be rather expensive and, so far, the need to mitigate climate change does not seem to provide sufficient incentive. A new study by researchers at UCLA, the University of Oxford, and five other institutions, analyzed the possibility of creating a large global industry based on capturing carbon dioxide and turning it into commercial products.

The study investigated the potential future scale and cost of 10 different ways to use carbon dioxide, including in fuels and chemicals, plastics, building materials, soil management, and forestry. The study looked at processes using carbon dioxide captured from waste products that are produced by burning fossil fuels as well as by simply capturing it directly from the atmosphere. The study also looked at processes that use carbon dioxide captured biologically by photosynthesis.

The conclusions of the study were that on average each of the ten utilization pathways could use about half a billion tons of carbon dioxide that would otherwise escape into the atmosphere. Thus, theoretically, these various pathways could take more than five billion tons of CO2 out of the atmosphere. Currently, fossil fuel combustion emits about 40 billion tons of carbon dioxide.

The authors of the study stress that there is no silver bullet in the fight against climate change. It will require multiple approaches – including CO2 removal for industrial use – to make real progress

Natural Climate Solutions

February 13, 2018 By EarthWise Leave a Comment

The Paris Climate Agreement embodies a commitment to hold the increase in the global average temperature to less than 2 Celsius degrees above preindustrial levels. Most strategies to achieve this goal involve reductions in greenhouse gas emissions from human activities such as burning fossil fuels as well as various land use activities. But there are also so-called Natural Climate Solutions, which relate to the storage of carbon and reduction in carbon emissions across global forests, wetlands, grasslands, and agricultural lands.

Catching Kelp In Maine

Farming, forestry, mining and recreation are the primary vocations in rural America. In coastal areas like Maine, fishing joins the list. And for Maine, commercial fishing has long been a major engine for the economy.
