The Decide Mérida digital platform was an opportunity that opened as never before the mechanisms of citizen participation for the elaboration of the Municipal Development Plan of Mérida 2018-2021. We had more than 3,000 citizen interactions including proposals, comments, suggestions and support that achieving the highest consensus possible about what is best for our city. Undoubtedly, the Decide Mérida platform will continue to be our ally in making Mérida an increasingly participative society.

We suffer under a lack of public space. It's particularly important that we reclaim these public spaces for us. Open platforms such as Decidim do exactly that. Is not only that is open source so other people can fork it, reuse it and build a process. It also has these values that we want to reflect in our society encoded in the way it's designed.

With the implementation of Decidim in Som Energia we have generated a kinder space for participation. We released the tool in 2018, hosting the General Assembly of the Cooperative and months later we debated the Image Redesign and collaborative development of the School of Som Energia, among other participatory processes. In a few months, more than 3,500 participant people have registered, 5 participatory processes, 3 assemblies operating and more than 1,300 votes in the last General Assembly vote.
