This chapter telescopes down further to look in more detail at the provincial seaweed industry of South Sulawesi. South Sulawesi is the largest seaweed-producing province in Indonesia and the home of the case study villages analysed in Part II of the book. This chapter outlines the features of the South Sulawesi seaweed industry. It begins by describing the establishment of the seaweed industry, influenced by the historic trading hub of Makassar. It then describes the current seaweed industry value chain: the range of actors operating across the production, distribution, processing, and exporting sectors. The chapter then explores each of these areas in detail, before concluding with a description of South Sulawesi seaweed policy. The chapter provides the context required to frame village-level analysis in Part II.
