This book delves into the popular "Food vs. Fuel" arguments and examines the complicated interplay between biofuel and agricultural markets. It provides information on forage crops as potential third-generation sources of bioenergy, and their cultivation practices. The areas covered include methodologies to enhance production efficiency of bioenergy, metabolism involved in cellulosic ethanol production, influence of policy and technical implementation, and the consequent impact on biofuels. The discussion of current difficulties impeding the expansion of the cellulosic biofuel business, as well as potential solutions are discussed as well. This book also covers case studies describing the present biofuel policies and its consequences on both the energy as well as agricultural sectors, as well as analysis of the current and growing biofuel market. The gathered information in the book is an excellent source for phenotyping, trait improvement, and developing future crop stress-management strategies and models. Students, scientists, policymakers, and investors in the bioenergy business will find this book to be a useful resource. Also, it serves as an excellent reference book for agriculturists, plant scientists, climatologists, and research scholars.
