The “Project of the Month Switzerland” (PotM CH) of April 2022 is about the collection of sustainable offers, i.e. stores and vending machines that are organic, regional, unpackaged, fair trade or second hand, and vegetarian and vegan restaurants as well as food sharing including water refill. Note the relevant tags and keys in the PotM documentation . The “Sustainable” web map  by user ToastHawaii nicely depicts most of the items.
Dashboard and Ranking
The April 2022 PotM-CH dashboard was given the number 19 . As before, it shows a ranked list of the mapper names that have edited the most. By the way, users geo_max and Geonick, currently ranked second and third, are out of contention. So currently imagoiq, sampeto and Necessary_Function are on the first three places.
Prizes and Mapathon/Hackathon 29 April 2022
The April 2022 PotM CH is a very special promotion with prizes to be won: The three most diligent mappers will receive small gift boxes from the farm! The prizes will be awarded at the Mapathon/Hackathon Rapperswil 2022, which will take place next Friday afternoon, April 29 . There are still places available at this Mapathon/Hackathon (“Ask us Anything”).
Sustainability Week Rapperswil 2022
The PotM CH prizes and pizza and drinks from the Mapathon were sponsored by Sustainability Week Rapperswil 2022 (NHWR22). Here is the whole program of the #NHWR22 .
What does “sustainable” mean?
The term “sustainable” has been defined rather restrictively in this PotM. It actually means much more, such as free repair offers, car and bike sharing, or environmentally sound waste disposal. Much of this has already been proposed in the PotM documentation  and could be done in the next months.
