Accordingly, clearing a hectare of forest translates into a total loss of TSh 16,767 per ha per year (2001) in terms of direct losses and losses incurred by other sectors, which is equivalent to TSh 83,771.70 per ha per year (2013). In this section we consider the question: “What is the contribution of the 17 industries modelled in the social accounting matrices to aggregate GDP?" Table 2 presents the contribution to GDP by sector (in descending order), highlighting the value added by the sectors of forestry and hunting, and that of wood, paper and printing.
