Fig. 2. Structure of Bayesian Belief Network (BBN) used to model the impact of NTFP commercialization on livelihoods. Factors are grouped in terms of the type of capital asset that they influence: natural (light green), physical (dark green), social (yellow), human (blue), and financial (red). The availability of each type of asset before commercialization influences availability after commercialization (denoted A in each case). Post-commercialization asset availabilities determine the impacts on livelihoods at both household and community levels, represented by separate nodes in each case.
