We continue with this series by discussing research topics related to Food Science, Intelligent Systems, Molecular Biomedicine, and Water Science. We aim to discuss the newest issues, theories, and research methods in each field, promote debates among top researchers and graduate students and generate collaborative works among them.

The interactions of recognized specialists in each field and graduate students, through different meetings, generated exciting discussions, which are presented in this book. Thus, Dr. Eusebio Juaristi, from the Department of Chemistry of the Center for Research and Advanced Studies of the Instituto Politécnico Nacional, contributes with the article titled "The 2021 Nobel Prize in Chemistry. Relevance of asymmetric organocatalysis and green chemistry". Dr. Toby P. Breckon, from the Department of Computer Science, Durham University, Durham, UK, with the article "Evaluating Convolutional Neural Networks for Prohibited Item Detection Using Real and Synthetically Composited X-ray Imagery". From the School of Chemical Sciences and DCU Water Institute, Dr. Fiona Regan wrote the article "Water quality monitoring using innovative technologies". Dr. Encarna Gómez-Plaza, from the University of Murcia, contributes with the article "ANTHOCYANINS and wine color: A complex story". Finally, graduate students of the Universidad de las Américas Puebla further present their key findings in a series of articles.

We believe that interactions between students and high-level researchers of different areas contribute to creating multidisciplinary points of view generating the advancement of science.

The number and impact of water-related natural disasters has increased since the middle of last century. As result of increased climate variability and the effects of global warming, the hydrometeorological risk has increased and spread, while the resilience of societies, in many cases, is not adequate. Consequently, the risk has increased. Floods and droughts, particularly in a changing climate, require greater understanding to generate better forecasts and proper management of these phenomena. Mexico, like other countries in the world, and of course in Latin America and the Caribbean region, suffers from both weather extremes.

The UNESCO Chair on Hydrometeorological Risks, held at the University of Americas Puebla, is devoted to the analysis, measurement, modelling and management of extreme hydro-meteorological events in the context of a more urbanized world, climate change and further vulnerable regions. Focused on the development of basic and applied research for the design of adaptation and mitigation measures, dissemination and preparation of decision makers as well as the public. In its activities keeps a gender focus, directed in particular to reduce the vulnerability of women to hydrometeorological disasters.

The Chair acts in the following fields:
