These models are solved for two extreme seasonal export scenarios and the solutions show that no export infrastructure expansion is required in the near future — observed bottlenecks are not fundamental to the infrastructure and its capacities, but are rather due to sub-optimal management and utilisation of the existing infrastructure.enMaximum flowSingle-community flowMulti-commodity flowFresh fruit exportFresh fruit export infrastructureArticleOrtmann, F., Van Vuuren, J., & Van Dyk, F.
