This visit to the University of KwaZulu-Natal was part of the joint CIRAD - UKZN PROTEA project focused on Integrated supply chain modelling applied to sugar cane. It was aimed at supervising the French student who works on the Noodsberg mill area in order to assess the impacts of mechanized harvesting on its supply chain. Two growers harvesting their cane mechanically were interviewed, as well as the mill procurement officer and the Sasri extension officer based in this area. A visit to the mill yard allowed understanding the cane off load systems in place and the various constraints linked to that part of the chain. Three mechanical harvest logistic chains were described based on these interviews and field observations. Discussions were led to conceptualize the logistic chain modelling and to design N scenarios based on various mechanized harvest ratios and kind of cane (green vs burnt). These scenarios will be simulated using jointly the ARENA and MAGI software. The harvester/lorries fleet size required to deliver a given amount of cane within a specific LOMS (Length of Milling Season) will be assessed, as well as the scenarios' impact on the sugar production of the mill area.
