Description
Aquatic foods from marine and freshwater systems are critical to the nutrition, health, livelihoods, economies and culture of billions of people worldwide – but climate-related hazards may compromise their ability to provide these benefits. This analysis estimates national-level aquatic food system climate risk using a fuzzy logic modeling approach that connects climate hazards impacting marine and freshwater capture fisheries and aquaculture to their contributions to sustainable food system outcomes, and vulnerability to losing those contributions. Estimates are presented for a high and a low emissions scenario in three different time windows (2030, 2050, 2090).
Notes
The datafile contains 6 tabs, for combinations of 2 emissions scenarios (SSP1-2.6, low-emissions; SSP5-8.5, high-emissions) and 3 time frames (2030, 2050, 2090). Each tab contains 23 variables for 240 countries and territories. All variables are of a unit-less score ranging from 1-100, where <25 indicates 'Low', 25-50 indicates 'Medium', 50-75 indicates 'High', and >75 indicates 'Very High'. Missing data are marked by empty cells, shaded grey. Countries and territories marked with an asterisk (*) are ones for which data availability was low, indicating reduced confidence in resulting risk scores.
The following variables are included:
- Hazard - Aggregate: Climate hazard score aggregated across all production systems based on present-day production weights; in all countries the 'post-production' component is assigned a weight of 10%
- Hazard – Marine fisheries: Climate hazard score for marine fisheries
- Hazard – Freshwater fisheries: Climate hazard score for freshwater fisheries
- Hazard – Marine aquaculture: Climate hazard score for marine aquaculture
- Hazard – Freshwater aquaculture: Climate hazard score for freshwater aquaculture
- Hazard – Brackish aquaculture: Climate hazard score for brackish aquaculture
- Hazard – Post-production: Climate hazard score for post-production processes
- Exposure – Nutrition_Health: Exposure score for the Nutrition & Health food systems outcome
- Exposure – Economic: Exposure score for the Economic food systems outcome
- Exposure – Social: Exposure score for the Social food systems outcome
- Exposure – Environmental: Exposure score for the Environmental food systems outcome
- Exposure to Hazard – Nutrition_Health: Exposure to Hazard score for the Nutrition & Health food systems outcome; scores were aggregated across all production systems based on present-day production weights; in all countries the 'post-production' component is assigned a weight of 10%
- Exposure to Hazard – Economic: Exposure to Hazard score for the Economic food systems outcome; scores were aggregated across all production systems based on present-day production weights; in all countries the 'post-production' component is assigned a weight of 10%
- Exposure to Hazard – Social: Exposure to Hazard score for the Social food systems outcome; scores were aggregated across all production systems based on present-day production weights; in all countries the 'post-production' component is assigned a weight of 10%
- Exposure to Hazard – Environmental: Exposure to Hazard score for the Environmental food systems outcome; scores were aggregated across all production systems based on present-day production weights; in all countries the 'post-production' component is assigned a weight of 10%
- Vulnerability – Nutrition_Health: Vulnerability score for the Nutrition & Health food systems outcome
- Vulnerability – Economic: Vulnerability score for the Nutrition & Health food systems outcome
- Vulnerability – Social: Vulnerability score for the Nutrition & Health food systems outcome
- Vulnerability – Environmental: Vulnerability score for the Nutrition & Health food systems outcome
- Risk – Nutrition_Health: Climate risk score for the Nutrition & Health food systems outcome
- Risk – Economic: Climate risk score for the Nutrition & Health food systems outcome
- Risk – Social: Climate risk score for the Nutrition & Health food systems outcome
- Risk – Environmental: Climate risk score for the Nutrition & Health food systems outcome
