Building new governance is not only an institutional or theoretical question confined to the political or sociological spheres. This is why we need to remodel governance architecture by incorporating it into the perspective of biocivilization for the sustainability of life and the planet. This architecture for a citizen-focused, solidarity-based and fair governance must be rooted in solid ethical and philosophical foundations. It must also both support and enable a new economy centered on social and environmental justice. What is needed is to work together to devise responses to today’s challenges, rooted in the contexts relevant to each person and each population. This involves recognizing the different forms of knowledge that exist in all continents, among all peoples, without trying to impose one of them as the unquestionable reference. The key conditions for a new governance must be formulated within a critical and democratic approach.
