MACBIO, or Marine and Coastal Biodiversity Management in Pacific Island Countries, is a pivotal initiative aimed at enhancing marine biodiversity management across various Pacific nations, including Fiji, Kiribati, Solomon Islands, Tonga, and Vanuatu. Launched as a project by the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMUB) as part of the International Climate Initiative (IKI), MACBIO focuses on building institutional and individual capacity to conserve marine and coastal ecosystems.

The organization's key offerings include marine ecosystem service valuation, marine spatial planning, and effective resource management. By conducting economic assessments of marine services, MACBIO ensures that results inform sustainable national policies and development strategies. The program also collaborates with local stakeholders to share successful conservation approaches, promoting sustainability in resource management. With a commitment to achieving national biodiversity targets and aligning with the Sustainable Development Goals, MACBIO is vital in safeguarding the marine resources that underpin the livelihoods of Pacific Island communities. Through its efforts, MACBIO champions the health of marine environments, thus ensuring their resilience for future generations.
