| description |
Effective harvesting and utilisation of log and logging residues are
important, in achieving the sustainable forest management and to maximize the
government revenue, in the light of declining supply of conventional logs.
The aim of this study was to evaluate the feasibility of harvesting and
extracting the logging residues, to estimate their economic value, to determine
quality and quantity of logging residues and types, to derive a volume equations
for quantifying logging residues, and to determine the factors affecting their
extraction. The type, quality and quantity of logging residues were determined
from two different tenures of timber concessions which were categorised into
three different operations based on altitudes, vegetation types, topography and
terrain characteristics. The "with" and "without" the Project approach was used
in determining the Incremental Net Benefit (INB) of harvesting and extracting
the logging residues. The economic value of logging residues was determined by applying formulas that express the concept of the stumpage value of timber.
The volume equation for logging residues was estimated using the OLS and WLS
regression methods following the normal volume equation for log. |
