Yield, Land Area & Woodfuel Accessibility

This guide from the Stockholm Environment Institute explains how to input yield, land area, and woodfuel accessibility data into a resource analysis tool, detailing the mathematical calculation of the overall access fraction based on location, tenure, and management factors.

• Biomass and renewable energy resource availability (yield) can be entered as a total annual value or as an annual availability per unit of land area, the latter of which requires corresponding land area data.
• Woodfuel accessibility is often below 100% due to three primary factors: distance from demand centers or transport routes (location access fraction, AL), legal or tenurial constraints such as parks or protected farmlands (tenure access fraction, AT), and the adequacy of harvesting tools (management access fraction, AM).
• The overall access fraction (A) is calculated as the product of the location, tenure, and management access fractions (A = AL × AT × AM), where these terms are calculated sequentially.
