UNOCHA specifically asks their work to be 'Credit as follows: "Credit: OCHA"', but obviously Wikipedia don't do it on their article page if you just embed the picture, you have to click on the picture to see the credit.
Actually, they even went further and removed the "OCHA" watermark from the original image (see File History).
To be honest, I wasn't super satisfied with the answers I got there (see ref), but then again I'm not familiar with this topic.
The linked CC licence states (and it appears to be confirmed that this is the licence that applies[1]):
> If You Distribute, or Publicly Perform the Work or any Adaptations or Collections, You must, unless a request has been made pursuant to Section 4(a), keep intact all copyright notices for the Work and provide, reasonable to the medium or means You are utilizing: (i) the name of the Original Author [...]; (ii) the title of the Work if supplied; (iii) to the extent reasonably practicable, the URI, if any, that Licensor specifies to be associated with the Work, unless such URI does not refer to the copyright notice or licensing information for the Work; and (iv) , consistent with Section 3(b), in the case of an Adaptation, a credit identifying the use of the Work in the Adaptation (e.g., "French translation of the Work by Original Author," or "Screenplay based on original Work by Original Author"). The credit required by this Section 4 (b) may be implemented in any reasonable manner
As the licence states that attribution must be reasonable to the medium and in any reasonable manner, having the attribution details on an information page would appear to be acceptable - the CC wiki[2] and FAQ[3] seem to support this:
> There is no one right way; just make sure your attribution is reasonable and suited to the medium you're working with. That being said, you still have to include attribution requirements somehow, even if it's just a link to an About page that has that info.[2]
> Additionally, you may satisfy the attribution requirement by providing a link to a place where the attribution information may be found.[3]
This is also made explicit in version 4.0 of the licence[4]:
> For example, it may be reasonable to satisfy the conditions by providing a URI or hyperlink to a resource that includes the required information.
Regarding removing the watermark, it does not appear to be a copyright notice, so the right to do so would seem to be implied by the right to make adaptions.

I agree, Wikipedia indeed does enough to attribute, but I'm still a little bit concerned about the specific "Attribution Requirements" listed on the File page (second block under #Licensing).
Basically it states, modified or not, you need to keep the source "below the map", which some Wikipedia article pages obviously don't.
What's your take about this "requirements" statement? Does it carry any weight, legally speaking?
(By "concerned" i'm not saying UN would have an issue with Wikimedia, just the technicality with such requirement).
My take would be that the CC licence used does not allow you to add additional attribution requirements, so either the image is not CC licenced (which seems not to be the case), or the requirements don't carry any weight (so are essentially a request/a guide to how they would like to be attributed). I will admit I'm less certain on this than the broader terms of the CC licence though.
Some of their pictures on Commons, such as https://en.wikipedia.org/wiki/File:Belgium_-_Location_Map_(2... , are from UNOCHA (United Nations Office for the Coordination of Humanitarian Affairs).
