Fig 1.
Agro-ecological zones of Nigeria and the three study states of the Lidiski project (Plateau, Bauchi and Kano), and their corresponding LGAs (inset).
Table 1.
Number and percentage in the Lidiski area (in parentheses) of states, LGAs, districts and villages from the market survey, FGDs and when combined (market and FGD) of small ruminant movements. In parentheses the percentage of states, LGAs, districts and villages that were in the Lidiski area.
Table 2.
Number and percentage (in parentheses) of small animal movements between villages as reported during the market survey activities, FGDs and when combined (market and FGDs). Internal survey area, both origin and destination were in the survey area; Incoming, only destination was inside the survey area; Outgoing, only origin was inside the survey area; External, none was inside the survey area.
Table 3.
Movements among the same states, LGAs and districts in the three networks versus movements among different states, LGAs and districts in the three networks.
Fig 2.
Map of the combined market and FGD network showing the LGAs where they overlap and the movement of small ruminants in Nigeria.
The LGAs in red show areas of small ruminant movements collected in the market survey, the LGAs in green show areas of small ruminant movements collected in the FGD survey, the LGAs in blue show the overlapping LGAs between both the market network and the FGD network. The lines show the movement links and the black points showed the survey markets.
Table 4.
Global network characteristics. Each row corresponds to a specific global measure. Each column corresponds to the market, the FGD or the combined (market+FGD) network.
Fig 3.
Frequency of movements and percentage of nodes in both pruned and unpruned market network (Supplementary material).
Fig 4.
LGA communities in market network, FGD network and combined small ruminants movement network.
Fig 5.
Histograms showing the distribution of communities among states in the three networks.
A) Number of LGAs (red) and states (blue) in each community. Each panel corresponded to a different network. B) The number of different communities the LGAs in each state belonged to. Different colors corresponded to different networks.
Fig 6.
Market network, FGD network and combined network sorted by indegree and outdegree.
The node size for both the indegree and outdegree corresponds to the LGAs with the largest indegree and largest outdegree, respectively.
Fig 7.
Bar plot showing the variation in quantile for potential super-spreaders and super- receivers.
The height of the bar corresponds to the variation in the centrality measure quartiles classes. Color corresponds to the network.
Fig 8.
Random removal and targeted removal of nodes for each network row, the size of the GCC is a fraction of the total original network after removal of a node.
In green, random removal (shaded area 95% CI after 50 simulations). Targeted removal (Red based on betweenness of the nodes; Orange based on Indegree; Yellow based on Outdegree).
