This manual that ILPES places at the disposal of public officials and non-governmental agents working in the community, has the purpose of sharing a brief theoretical reflection on the current socio-political context through which this manual becomes important; and a set of methodological instruments that will bring the user closer to the social practice of a citizen participation process in the construction of a public management instrument. The manual is divided into two chapters: The first conceptualizes participatory multiscale planning, while also briefly introducing three topics of great importance to be incorporated into any participatory planning process and construction of public management instruments: the perspective of gender, the use of Convention 169 and Principle 10. The second chapter systematizes a set of methodological instruments that describe the stages of a citizen participation strategy to incorporate the multiscale public management instruments. The manual closes with two annexes, the last of which incorporates a set of tools that can be used in the stages of the construction of a citizen participation strategy.
