What is a 'transboundary risk' and give an example relevant to geospatial risk management?

• A. Risks crossing borders due to shared resources or supply chains; example: river flooding affecting multiple downstream factories in different countries, requiring coordinated risk response.
• B. Risks confined within a country with no cross-border impact.
• C. Risks only in digital space.
• D. Risks only related to personnel safety.

Answer: (A)

Transboundary risk means a hazard or consequence that crosses political borders, affecting more than one country because of shared resources, cross-border supply chains, or connected systems. In geospatial risk management, we map how a hazard footprint extends across borders and plan collaborative responses that span jurisdictions.

The given example fits this idea well: upstream river flooding in one country can inundate downstream facilities, infrastructure, or communities across an international border. This creates cascading impacts on production, logistics, and livelihoods in multiple nations, so coordinated risk response, shared data, harmonized early warning, and cross-border contingency planning are essential to manage the risk effectively.

The other descriptions describe risks that stay within a single country or are non-geospatial in nature, so they don’t capture the cross-border interdependencies that define transboundary risk.
