This research provides a brief review on several topics as a foundation to comprehend the current situation on water and hydrological resources management and monitoring at a local scale, considering the case of the Tabacay river micro-basin the southeast of Ecuador. This study is performed in aims to explore the data collected by representative meteorological and pluviometry stations of the corresponding geographical space withing the micro-basin. In this context, a comparative analysis on rainfall for the recent years is provided. It also presents the evaluation of the existing challenges in the water and sanitation management and further recommendations for control and use of the natural resources in subject.

This research provides a literature review on several topics as a foundation to comprehend porous materials, their structure, and behavior to explore how they can be derived from clays and nanoclays. In this case, considering the several minerals present in some Ecuadorian clays, which are a potential starting material for the synthesis of porous frameworks, they constitute a solid source of metal atoms such as Silicon or Aluminum. This research presents the evaluation and characterization via XRD and AAS of clay samples collected in the southeast of Ecuador in the provinces of Azuay, Morona Santiago and Zamora Chinchipe, which present diversified soil mineralogy with many chemical and crystallographic features for suitable precursors in nanomaterials design.
