WIOSAP addresses major threats to critical coastal and marine ecosystems of the Western Indian Ocean region. It has four components:

A: Sustainable Management of Critical Habitats

Critical habitats such as coral reefs, mangroves, and seagrasses have enormous ecological and economic value for the region—but are more vulnerable than ever. Outcomes under this component will include a) critical habitat management through pilot interventions and b) the development and adaptation of tools and methods to support coastal planning and management.

B: Improved Water Quality:

Untreated wastewater and effluents are causing a decline in water quality in the region, threatening public health and ecosystems. Outcomes under this component will include improved quality of coastal “receiving” waters through pilot interventions and a framework for monitoring and managing these pollutants.

C: Sustainable Management of River Flows

Human activities and climate variability have altered the drainage systems of many rivers in the region. Such alterations threaten coastal habitats, shorelines, public health, and livelihoods. Outcomes under this component will include environmental flow assessments (EFAs) and implementation of EFA plans in the region, including through pilot interventions.

D: Governance and Regional Collaboration

The degradation of critical marine and coastal ecosystems in the region can be partially attributed to inadequate governance frameworks. Activities under this component will include an improved knowledge management system (see the Nairobi Convention’s Clearing House Mechanism) and exchange mechanisms, as well as updated policies and stronger institutions.
