Fellow Martin Weber’s colloquium on his research project at the Academy and the book he is writing in Bonn focused on how fundamental ecological and social issues can be considered together. This complex intertwining can be seen as one of the major challenges for meaningful political transformation that, for example, halts the harmful effects of modern agriculture on the climate and reduces the pressure on societies caused by the demand for rapid economic growth. Looking at successful local projects, for example in Ethiopia, Andalusia, and Mexico, Martin Weber highlights the possibilities for implementing model projects in solidarity-based communities in the long term and how this can contribute to global learning. For example, the experiences of well-known groups such as La Via Campesina, which campaigns for food sovereignty and against genetically modified seeds as well as against violence against women, can guide action for solidarity-based transnational localism. Martin Weber thus shows an important way in which progress is possible even in phases of political stagnation.
