Ecosystem Risk from Human Activities at Trindade and Martin Vaz Islands

515 impact chains linking socioeconomic sectors to ecological components were identified through a structured expert elicitation process. The dataset results from an Integrated Ecosystem Assessment (IEA) using the ODEMM framework, quantifying risks from fishing, military, shipping, tourism, and research activities. It was authored by Ana C. Suhett and last updated on 2026-04-23.

Use Cases

• Prioritizing management actions based on quantified Impact Risk (IR) scores for different sectors.
• Analyzing network connectivity of human pressures based on the proportional connectance analysis mentioned.
• Evaluating the effectiveness of Marine Protected Areas (MPAs) in mitigating identified impact chains.
• Supporting adaptive governance strategies based on the transparent, replicable framework described.

Strengths

• Dataset is derived from a structured expert elicitation process involving stakeholders.
• Analysis identified 515 distinct impact chains (sector → pressure → ecological component).
• Impact Risk (IR) was estimated using a multiplicative combination of spatial overlap, frequency, and degree of impact scores.

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 (11.8 KB), indicating limited raw data or a summary document.
