18. Mathematical Model BIOMASS Theoretical Potential - is the total annual production of residues in a region. It is a function of cultivated area and the biomass production yield of each crop: Where:

19. Mathematical Model BIOMASS Available Potential - refers to the energy content of the biomass potential. Where:

26. BIOMASS Initial Results Please note: Data used to fom this map is very old (1980’s DA) and may no longer be applicable to the present. We just used this to test our work flow and mathematical model since lidar derived crop areas are not yet available to us as of now.

29. BIOMASS Summary Crop areas were identified using Landsat images. From the delineated crop areas, the validity of the mathematical model was tested together with other parameters derived from statistical data. LiDAR-derived crop areas, once available, will be used for the final assessment of biomass available potential.
