Fig. 2. The REDD+ policy network in Central Kalimantan, Indonesia. Letters denote organization type (G = Provincial Government; N = Nongovernmental Organization; R = Research/Academic Organization; D = Donor Government Agency; I = International Organization). Nodes are scaled by normalized betweenness centrality (Freeman 1978), defined by a count of the number of shortest paths between all pairs of nodes in the network incident on a given node. Calculated in statnet (Handcock et al. 2003) and visualized with ggplot2 (Wickham 2009) in R 3.0.1 (R Development Core Team 2013).
