Ecosystem Risk Assessment for Trindade and Martin Vaz Islands, Southwestern Atlantic

515 impact chains linking socioeconomic sectors to ecological components were identified through a structured expert elicitation process. The dataset, created by Ana C. Suhett and last updated in April 2026, applies an Integrated Ecosystem Assessment (IEA) using the ODEMM framework to quantify risks from fishing, military, shipping, tourism, and research activities.

Use Cases

• Prioritizing management actions based on quantified Impact Risk (IR) scores for different sectors.
• Analyzing network connectivity and risk intensity for military and shipping activities.
• Evaluating the effectiveness of Marine Protected Areas (MPAs) in mitigating identified risks.
• Modeling cumulative human pressures on pelagic fish, shallow reefs, and sedimentary habitats.

Strengths

• Provides a transparent, replicable framework for ecological risk assessment in data-limited systems.
• Identifies 515 specific impact chains (sector → pressure → ecological component).
• Quantifies risk using scores based on spatial overlap, frequency, and degree of impact.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (32.8 KB), suggesting it contains summary or methodological data rather than raw observations.
