DESCRIPTION

Compute the theoretical biomass forestry residual potential, based on the annual/periodic forest increment.

NOTES

This module permits to evalute the maximum bio-energy from forest residual available in a particular area, on the base of the annual/periodic forest increment. The mandatory data input are a vector file with fields with values of increment, management, treatment, and forest surface. The increment value is expressed in cubic meters, the forest surface in hectares, the management is an integer value that can be 1 for high forest and 2 for coppice, the treatment is an integer field that can be 1 for final felling and 2 for thinning. The energy section contains the calorific parameters that permits to convert the biomass in energy. The output maps are expressed in Mwh.

EXAMPLE

This example shows a typical input vector file with a table composed by fields of increment, forest surface, management and treatment. This example is based on data of MaÃ¨ Valley, one of the test area of the R.green project

The output map is a standardize energy map with the pixel value equal to the corresponding bioenergy stimated.
