Description

The article summarizes the results of the multi-year research on reducing greenhouse gas emissions, carbon storage increasing and greenhouse gases limiting in the managed forests of the Far Eastern Federal District (FEFD) in accordance with the Paris Agreement [1]. The forests of the Far Eastern Federal District (FEFD) cover 43 percent of the total forest lands of the Russian Federation, and their conservation and assessment is one of the important tasks for compliance with the Paris Agreement. Logging and fires in the studied area lead to significant emissions of greenhouse gases into the atmosphere. Therefore, the aim of the study is to assess the carbon budget in the managed forests of the study area to develop the recommendations for reducing CO2 emissions into the air basin. The study of carbon losses in the managed forests of the FEFD (on the example of the Khabarovsky Krai) was carried out using the Regional Forest Carbon Budget Assessment (ROBUL) Program [2]. It was found that the area of burnt forest areas in the Khabarovsky Krai for 2018 was 3 million hectares and the area of logging is 313 thousand hectares, which leads to the losses of about 20 million tons of C per year-1. It was found that as the age of stands increases, significant accumulation of greenhouse gases occurs not only in biomass, but also in litter and soil. Destruction of tree and shrub vegetation due to clear-cut harvesting and forest fires, as well as the mineral resources development, leads to environmental and socio-economic impacts. As a result of the conducted research, the losses of CO2 have been assessed and the measures to reduce greenhouse gas emissions and carbon storage increase in the managed forests of the FEFD (on the example of the Khabarovsky Krai) have been scientifically established. The need for rehabilitative measures to increase carbon stock through conservation and multiplication of forest land (including reclamation) is evident.
