Green technologies mainly focus on renewable energy sources, sustainable
agricultural practices, phyto-/bioremediation of contaminants, biofuels, sus-
tainable utilization of resources, green buildings, green chemistry, and green
economy. All of these eco-friendly technologies will help to reduce the
amount of waste and pollution and enhance the nation’s economic growth in
a sustainable manner. We hope this book will bring out the recent advance-
ment and application of different green technologies and strategies imple-
mented worldwide and this will pave the way for sustainable environment.
The contents of the book is aimed to provide an integrated approach to sus-
tainable environment, and it will be of interest not only to environmentalists
but also to agriculturists and forest and soil scientists and in bridging the gap
between the scholars/scientists and policymakers.
