Ecology, environment and agriculture are inseparably allied. Agriculture, in essence, produces foods by transforming natural environments and manipulating ecological processes. Environmental factors determine structure and functions of an ecosystem.

This book attempts to collate many chapters written by well-known ecologists, environmentalists and agriculturists which discuss critical issues, perspectives and strategies influencing our ecosystems, physical environment and food production processes. It calls for evolving agricultural practices (agronomic, plant breeding, extension, communication, etc.) and systems that not only feed human populations on sustainable basis but also take care of ecosystem functioning and help optimize environmental factors so that agriculture also takes care of the environment and natural resources on which it vibrantly relies.
