All photos of this flickr account (account name: gtzecosan) are under the CC-BY SA 4.0 license.


Note: in the flickr settings, the closest to this is the CC-BY-2.0 license which is why the photos show up under that licence but our intent is for the photos to be under CC-BY SA 4.0 license - for maximum compatibility with Wikipedia.


These photos started as a collection of ecosan photos by staff members of then GTZ (now GIZ) in Germany. Over time, the collection has been widened to include also other sanitation topics (technical and non technical), and the photos are provided now by many people working for many different organisations.


We now regard this photo collection as a collection of the Sustainable Sanitation Alliance (SuSanA). It is however not possible in flickr to change the login name of an existing account, so the URL for photos in our collection contains the word "gtzecosan", whereas our preferred name would now be "susana_giz" (the name of our company, GTZ, has changed to GIZ on 1 January 2011).


The photos are grouped by country or by topic, and can be searched via keywords (words appearing in the title or as tags). Use the tag "rating-A" to find photos which are really good, or use the tag "rating-Z" to find photos that show a very bad situation in terms of lack of sanitation.


The photos have been contributed by various people, and all the photographers' names are given with the photos or the respective photo sets.


The photos are all available under Creative Commons Licence (CC-BY SA 4.0 license) and you are free to use them for any purpose that you like, even commercial purposes. It is a nice touch (but not compulsory) to let us know where you have used our photos (by leaving a comment with the flickr photo).
