Four water basin councils were selected for in-depth study, two in Peru and two in Brazil. Peru and Brazil’s water councils present diverse characteristics – such as the time they have existed for, the way their participants are selected, or the type of management system in which they are inserted (see figures) – while being in the same region, which makes them interesting to compare. The researcher, during fieldwork, interviewed participants in the selected councils to try and understand their vision of the basins as well as their vision of the participatory mechanisms in place for water management. Other important actors for the water management system were also interviewed; these actors included actors occupying key positions at the national level and actors who had been involved in setting up the studied councils. Institutional documents that portrayed the different organizations’ visions of water management and that provided information on projects conducted by these organizations were also collected during fieldwork. A mixed methods approach was used to analyze the data. Indeed, the qualitative data – text and open questions in interviews – was analyzed following a thematic analysis, in which the identified key themes of the literature were contrasted and refined in light of the empirical data. The quantitative data was analyzed through network and statistical analysis; this allowed to explore the variables that suggest explanations as to how actors relate to each other and why. Three academic papers are being prepared to explain the results obtained through the above mentioned analysis.
