[Citizen security observatories: tools for decision making and governability].

The need for good governability to promote countries development has been becoming the focus of governments. Latin America has political systems in crisis of governability caused by the inability of strategic actors to solve conflicts based on rules and procedures. The present review aims to describe how the creation of violence surveillance systems (observatories) contributes to strengthening governability and the creation of effective public policies. It was developed an analysis of the required components for the existence of governability and its relationship with the role of observatories in cities to provide reliable, timely and representative information that allows the formulation of strategies and policies. Governability is enriched with the legitimacy granted by the public from the results obtained by the governments in the formulation, implementation, evaluation of public policies and the evidence-based decisions in public health.
