Sorry this is in French but I think many movements have a similar enough name that English speakers will understand what "écosocialisme" or "écologies anti-industrielles" means. A note though: "libertaire" is not "libertarian" it is closer to "liberal" with a stronger left-wing bias.
I found it interesting because while they mention that it is extremely hard to make such a map and that it has tons of very debatable links and placement, I still see solarpunks being all over the left 2/3 of the map.
My feeling is that it is a label for anarcho-communists who got tired of explaining their relationships (or lack thereof) with marxist communism. Also used by "communistes libertaires" to emphasize they reject the authoritarian regimes that called themselves communist.
This is pretty cool thx. I like how they include both the researcher and their seminal works. It also helped me find another researcher that was into low tech other than Philippe Bihouix. I wonder why most researchers that are into that are French?
This map was made by French so it may have a bias there. But I know there is a very active lowtech community here in France. As a techno-utopian I spent a long time ignoring them until someone told me that the raspberry pi is lowtech and that I am doing lowtech robotics (wth?) . Here it basically seems to be a synonym for open hardware, with an emphasis on community rather than projects. It is actually pretty chill.
