This chapter argues that for a successful negotiation of new eco-social contracts to happen, the democratic deficit of our political systems needs to be addressed allowing for more meaningful ways to confront power through agonistic practices, understood as those practices that are less concerned with consensus and more with allowing and regulating conflict. To illustrate the potential of this political theory in our modern democracies I will examine the ways in which different actors in Latin America engage with existing political systems. More specifically, I will look into the Mexican feminist collective Zines por morras, the Youth for Climate movement in Argentina, the three decades of operation of the Mexican Network of Forestal Peasant Organisations and the Articulation of Indigenous Peoples of Brazil. The aim is to identify existing conflict dynamics in these movements and how much these movements have been able to integrate them into their internal structures for decision-making.
