The short answer: simply use a background map that is available under a more permissive licence, for example the “Humanitarian” layer.
The long answer:
- you should have sent your question to legal-questions@osmfoundation.org
- the ODbL, that is the OSM data distribution licence allows works that are created from the data that are not databases to be licensed on a wide range of terms, essentially requiring just attribution of the data source
- for historical reasons, the map images aka tiles, in the “standard” style from openstreetmap.org are licensed on CC BY-SA 2.0 terms which is more restrictive than the licence of the journal, other layers are licensed on other terms.
In summary to be compatible with the license of the journal, you can either render the relevant area in OSM yourself, or use a layer from openstreetmap.org or elsewhere that has compatible terms.
Note: it should be pointed out that very likely your use would be covered by fair use / fair dealing in any case, but you probably don’t want to start an argument about legal fine points with the journal.
