oppblomstring

Oppblomstring is a Norwegian noun that denotes a period of renewed growth, activity, or prosperity following a decline or stagnation. The term is formed from opp- meaning up or upward, and blomstring meaning flowering or flourishing, and is cognate with Swedish uppblomstring, Danish upblomstring.

In socio-economic and cultural contexts, oppblomstring describes revival after difficult times: a boom in industry, a cultural renaissance, a surge in creativity. It can describe historical episodes, such as a postwar economic upturn or a new wave of literary production.

In biology and ecology, oppblomstring can refer to rapid population growth or blooms of organisms in a medium, especially algae in water bodies. Such blooms can be natural or driven by nutrient enrichment and climate conditions, and may be harmless or harmful depending on species.

Usage note: The word is most commonly used in Norwegian discourse; in English or other languages, equivalents such as "boom" or "revival" would be used.
