For years, a citizens' initiative in the Indonesian Kendeng Karst-Mountain has been fighting against the destruction of their livelihoods by cement factories, among others, a subsidiary of the German HeidelbergCement. The transnational solidarity network Save Kendeng supports the farmers from the Kendeng Mountains.
Solidarity works involving communities from two different countries, Indonesia and Germany is a result of a collaborative work facilitated by usage of media technology. Social movements are no longer only read as a local entity with specific actors and issues but can be read within the framework of engagement with other actors and issues, both at local and international levels.
