Nano Biogeotechnology is the use of biological, ecological and geotechnical engineering data to solve geological problems. Applied biogeotechnology focuses on using plants and human-made structures to control erosion, protect slopes, and restore environmental quality. Consideration of soil as a living ecosystem offers the potential for innovative and sustainable solutions to geotechnical problems. This is a new paradigm for many in geotechnical engineering. Realising the potential of this paradigm requires a multidisciplinary approach that embraces biology and geochemistry to develop techniques for beneficial ground modification. Language of the book is a simple presentation is lucid and unambiguous for easy understanding of the subject matter. This book is very useful to undergraduate students and teachers as well to get in-depth knowledge of this subject.
