transboundary

Across national lines

Transboundary describes something that crosses or extends across political borders, especially between nations.

The term appears most often in environmental and legal contexts: transboundary pollution, transboundary water resources, transboundary protected areas.

A river flowing through multiple countries creates transboundary management challenges.

The word emphasizes that certain issues—pollution, wildlife migration, disease—don't respect the lines humans draw on maps.
