A framework for inferring predictive distributions of rhino poaching events through causal modelling. In: FUSION 2014, Salamanca, Spain, 7-10 July 2014http://hdl.handle.net/10204/7631FUSION 2014, Salamanca, Spain, 7-10 July 2014Rhino poaching in South Africa is leading to a catastrophic reduction in the rhino population. In this paper a Bayesian network causal model is proposed to model the underlying (causal) relationships that lead to rhino poaching events. The model may be used to fuse a collection of heterogeneous information sources. If a game reserve is partitioned into several geographical areas or cells, the model may perform inference for each of these cells separately, and give a relative predictive distribution of poaching events over the game reserve. After an overview of the current problem definition and a brief overview of similar modelling approaches, the Bayesian network model is presented. The developed Bayesian network based model is an initial attempt at proposing a sensible modelling approach for this problem. Some of the complexities of the approach are discussed, before considering how the model may be validated at a later stage.enRhino poachingModelling approachesBayesian network modelsCatastrophic reductionConference PresentationKoen, H., De Villiers, J., Pavlin, G., De Waal, A., De Oude, P., & Mignet, F.
