Fig. 2. Organizations in the REDD+ policy arena in Nepal that regularly discuss and exchange information (a) and collaborate (b) with each other on REDD+ issues. N = 34 organizations. The size of nodes indicates degree centrality, i.e., the number of incoming and outgoing ties. Circular nodes indicate actors in the core; square nodes indicate actors in the periphery. Node color denotes organization type, as indicated in the key. Numbers accompanying each node correspond to the organization identification numbers (Table 3).
