10 Questions to be solved
1. ¿Estructure of a model/complex of modelsfor forecasting and analyzing scenariosabout Galician Forestry Sector and Wood‐Biomass supply/demand?
2. ¿What is the information needed? ¿is itavailable?¿how can we obtain the notavailable one?
3. Is it posible using PNOA‐LiDAR, to refine the existing information of forest resources withproductive of Galicia? ¿Is it posible to tune INF4 y el MFE25 with that
technology? ¿What are the results in pilot areas?
4 How can Ownership fragmentation be mesaured to beconsidered into the Wood resource balance?
5 ¿How can forest management withdrawal (abandon) bemesaured to be considered into the Wood resourcebalance?
6 ¿How can impact of private owners management decisionsbe considered into the Wood Resource Balance?
7 ¿How can impact of legal restrictions be considered intothe Wood resource balance?
8 What are these efects on potential wood availability in pilotareas?
9 Can these results be extrapolated to the whole area?
