Solid cubic meters of forest trees and their annual growth in Finland since 1921

Kuva
At national level the most remarkable above ground Carbon stock in Finland is in the forests. The most common basic measurement for the forests, is the amount of above ground solid cubic meters in the trees. It is normally measured for the stems only. The data correlates strongly with the total dry biomass in the trees (stems, branches, foliage, stumps and roots). Further, the solid cubic meters data correlates strongly with the amount of elementary Carbon in the trees (stems, branches, foliage, stumps and roots). Photo 1. Boreal forests are a remarkable Carbon stock in Finland. The changes in the amount of solid cubic meters in the trees indicate the changes in the Carbon stock. Positive change tells about the Carbon sink flux into the forests. Negative change tells about the Carbon source flux (or Carbon emissions flux) from the forests.  The regular inventory of forest trees, for their solid cubic meters, has been done in Finland since 1921 (Figure 1). The latest National Forest I

Reference Carbon fluxes in Finnish Carbon husbandry

Kuva
The important, key fluxes in Finnish Carbon husbandry are the two: (1) positive Carbon sink flux to Finnish forests and (2) negative Carbon emissions (source) flux from Finnish arable lands. The most accurate data in Finland have been measured for (1) in Finnish forests. In the year 2020 there is the calculated average Carbon sink flux to Finnish forests of magnitude +393 kg C/ha/a.  Picture 1. Coppicing Downy birch - promising tree species for boreal Carbon husbandry in peatlands The most accurate data for Finnish arable lands (2) has been measured for mineral soils. In the year 2020 there is the calculated average Carbon emissions flux from Finnish arable lands of magnitude -430 kg C/ha/a. (Figure 1). Figure 1. Reference Carbon fluxes. Sink fluxes positive, source (emissions) fluxes negative. There is still less comprehensive measurement series for Carbon emissions from arable lands on peat soils. However, it is assumed that the emissions from a peat arable hectare are about 10 tim

Forest Carbon number and Forest Carbon flux in Ethiopia

Kuva
Forestry in general and carbon husbandry especially, are quite different in the  tropical highland country Ethiopia and in the boreal lowland country Finland. When Finland is basically covered everywhere with closed forests, Ethiopia has a mosaic type scenery where closed forests are rare. The densely populated highlands are now basically open agricultural and grazing areas. Modern agroforesty is changing the situation as smallholder farmers are planting trees along the borders of their parcels, and small woodlots for fuelwood and for traditional small house building. The Picture 1 describes the Ethiopian highland setup. There is an indigenous, original forest in the centre. It has been culturally conserved around a local coptic church (in a Sekela village, in Amhara region). The church area is surrounded by smallholder farmers crop fields with more or less scattered trees planted by the farmers themselves. Food and Agriculture Organization (FAO) would define the block in the centre of
