La Hidra Cooperativa is a political organization that focuses its work on urban transformation, with the objective of joining the group of professional and social practices that want to guarantee the right to the city. Our action is based on three services that we offer to public, community or private entities: research, consulting and training. Through our work, we aim to produce practical knowledge to intervene in three strategic areas: urban economy, common goods and peripheries. The work in these areas forms a critique of urban political economy, i.e. tools, data and knowledge to identify the origins of urban inequalities and to propose alternatives.
