Fresh water is increasingly becoming a global resource driven by growing international business. Due to the concerns of global water scarcity and food security, there has been much interest in the water footprint indicator which is popular with sound public perception to assess product environmental impact of water use and to further undertake supply chain management. This study applied a process-based life cycle assessment (LCA) method to calculate the water footprint of sweet potato noodle at brand level. The results demonstrated well practicality of water footprint as streamlined indicator in product supply chain management for the selected product. Footprinting value was compared among different life cycle stages and possible mitigation strategies were put forward for water use reductions throughout the supply chain.
