Public investment in science and technology is a key vector of socioeconomic development, especially when the results of this scientific production are transferred to society. In countries characterized by immature national innovation systems, as is in Brazil, the expenditures made by government for the development of science and technology assume even greater importance due to low expenditures made by private companies. In this context, the area of water resources is particularly relevant due to the strategic importance that adequate availability of water represents to society, and the direct relation to another strategic vector of social development namely energy production. This exploratory and descriptive study employs historical data about the projects implemented with financial resources of the CT-HIDRO Sectorial Fund of federal assistance, and of the Araucaria and Copel Foundations, both of state assistance in the State of Parana, from 2003 to 2008, in order to identify trends - increasing, decreasing or stable, and their correlations - such as the adherence of the projects executed with the strategic guidelines for water resources, and its contribution to the energy sector of the State of Parana. Main results show a positive evolution of the program of water resources in the State of Paraná, with a significant increase both of research groups and the participation of foreign scholars in the area of water resources, showing that federal and state programs take complementary actions in the promotion of the area.
