Rapid expansion of the Indonesian aquaculture sector has outpaced the development and implementation of adequate governance and management, exposing market , environmental, and disease risks that can occur beyond individual farms. A jurisdictional approach to sectoral improvement that addresses such risks at politically, economically, and ecologically relevant scales can provide the basis for economic growth with improved environmental performance and resource efficiency and reduced disease risks . Conservation International, in partnership with Sustainable Fisheries Partnership, IDH - the Sustainable Trade Initiative, and Longline Environment is implementing a jurisdictional approach improvement program with the shrimp aquaculture sector in the Banyuwangi Regency of Indonesia to improve production and attract innovative finance vehicles. The program will test the ability of jurisdictional initiatives to transform the aquaculture sector towards increased production and profitability with reduced environmental and disease risks . Our approach is designed to address multiple commercial, political, and environmental barriers to create a scalable and investible model for improvement that can be replicated in other geographies and aquaculture sectors. This talk will highlight novel components of the program and key lessons learned during implementation.
