Why is it necessary to present both biomass and carbon stock values in the results section when we are calculating the latter from the former? Any explanation?
Hello, You can further calculate the CO2eq from carbon stock but biomass not giving such information which will further help to know the carbon sequestration potential of individual tress. Kindly see my published papers to know more information.
As you know, biomass is an important basis to derive many indices that may have very different roles on eco-environmental conditions. carbon stock is one of these indices and introduced as "amount of carbon that has been sequestered from the atmosphere and is now stored within the vegetation ecosystems, mainly within living biomass and soil, and to a lesser extent also in dead wood and litter". This index could help us to have better comparisons between different ecosystems and even investigate the human effect and climate change on the ecosystem services.
Your welcome. Actually, this subject is out of my interest. But as I understand from some papers, for example, the vegetation diversity and some ecological indices could be divided. I hope the below papers will be useful in this regards:
It is up to the system boundary you have. But general speaking, C-storage and the increase or the decrease of it in the sense of CCU is important for the C-calculation of a LCA: Normally plants are absorbing the C and burning of wood or burning of biogas from substrates is nearly equal. But in terms of the forest, an extended usage of wood can both increase or decrease the C-storage of the forest system (Article The climate change mitigation effect of bioenergy from susta...
). It depends on the age of the forest and the overall increase of several years.
Also in agricultural systems you may have a land use change or even an indirect land use change, if you use the agricultural land for bioenergy.
1. Biomass estimation in forest ecosystems is an important aspect of forest management processes aimed at ensuring sustainability.
2. Biomass inventories are also used by industrial manufacturers of forest products and bioenergy for assessments of resource availability and location of production facilities.
