Objectives: As part of a large transport sector improvement program, the Government of Fiji, supported by the Asian Development Bank (ADB) and the World Bank (WB), aims to upgrade and improve three maritime structures at Natovi Jetty (Viti Levu Island), Savusavu Jetty (Vanua Levu Island), and Nabouwalu Jetty (Vanua Levu Island). This involves conducting aquatic ecological studies to establish the baseline ecological conditions, assess project-related risks to the aquatic environment, and propose necessary mitigation measures. The studies are focused on determining ecological and habitat values, emphasizing endemic, rare, or endangered species and ensuring compliance with ADB and WB's environmental safeguard policies. This initiative is critical for informing the creation of Environmental and Social Management Plans or Environmental and Social Impact Assessments.
