In this same context, the University of Valencia, Spain, in collaboration with the Pontificia Universidad Católica del Ecuador Sede Ibarra, carry out research to determine the technological capacity of students in the different areas of knowledge taught at the University of Valencia.

As internal authors, three articles by professors from the PUCE Sede Ibarra and one from the PUCE Sede Esmeraldas are presented. One of them aims to evaluate the effects of the application of microbial extract from native soils on soils impacted by forest fires in the Loma de Guayabillas (Ibarra).

Another presents a conceptual synthesis of strategies to achieve urban sustainability, related to environmental and life quality, based on a spatio-temporal vision, seeking to guarantee resources for future generations. Another article aims to make visible the current state of community radio communication in the province of Imbabura through the analysis of three radio media to learn about the programming and the commitment established with the community to which they are due.
