Civilizations depend on agricultural innovation processes at local, regional and global scales for food security. Crop diversity resources are the bases of these processes. Crop resources are natural assets that are very significant for fulfilling the growing food demand of the population in the world but these are vulnerable to damage from either natural or human made interventions, including the disturbances caused by natural disasters, climate variability as well as the gradual socioeconomic changes. Technological changes in agricultural production over the past century, stimulated by improvement in crop genes combined with the use of either farm inputs, have transformed rural societies in many parts of the world. All these factors lead to changes in the crop diversity over the period of time. This book, therefore, provides the detail of the emerging scenario of crop diversity in an Indian district. The analysis should unfold the dynamics of crop diversity in the district and environmental implication due to changes. This should be useful to professionals or anyone who is interested in the concerned issue.
