The book presents various experiences realised over 20 years in Higher Education, related to the specific didactics of Geography and Environmental Studies at all levels of education, although with a greater focus on Pre-school Education and the 1st Cycle of Basic Education. The second part presents some reflections on the teaching of Geography and the need to give this science the importance and prestige it deserves, as an essential basis for the integral formation of citizens. This is an unpretentious book, but it is an aid to teaching practices for colleagues and readers interested in education and geography.

Some ideas on how to introduce concepts of Geography in the beginning of school years. The landscape and narratives as didactic tools, essential to the formation of children and future citizens. In a era of integration of spaces, the formation and education of children, the school and their professionals can find some clues for reflection and paths to their daily pedagogical practice. The training of teachers seen by themselves starting in Portugal but reflecting a wider reality.
