Sun: fragile interface | Pierre Stengel, Sandrine Gelin

Once used simply as a support for farming or as a filter conditioning water quality, soil is finally recognized as a living environment that must be preserved for the future. This book, a valuable educational tool, synthesizes the knowledge necessary for this new approach to the soil ecosystem and its functioning: as a place of exchanges and transfers, soil is also a biotransformer characterized by the complexity of the relationships involved. Through specific examples, it demonstrates how certain human land uses can suddenly endanger the balances achieved: salinization, erosion, contamination... and makes proposals for better soil management. Based on the Life Sciences and Earth Sciences programs in secondary education, this book is particularly aimed at teachers and students - it also serves as a good introduction to scientific higher education programs.
