Zonernas

Could you clarify what "zonernas" refers to? Is it a Swedish term meaning "the zones" in the context of geography or urban planning, or is it the name of a specific concept, group, or fictional element? Providing a bit of context (historical, contemporary, academic, or fictional) will help me write a concise, neutral wiki-style article under 300 words. If you’d like, I can also provide a general overview of zoning and zonal concepts.
