This book discusses the history of environmental science and
climate change, and the initiation and development of different
parameters determining climate changes. The account of the history
of such changes and turmoil in India and abroad starts in the
prehistoric period, long before the emergence of "Rigveda", the
first human written work. The book describes the writings of
Aristotle and Theophrastus on climatic disasters and their impact
on the vegetation and society in Greek and Roman history, and
addresses different studies related to climate change during the
prehistoric period and their chronological development. The first
book of its kind, it enhances our understanding the origin of
research on climate change and climate related problems, and as
such is a valuable resource for postgraduate students of
agriculture and environment sciences, research scholars,
scientists, environmentalists and policy planners.
This is a research based study for characterization of
physiological and biochemical responses of crop plants to elevated
level of atmospheric CO2 concentration which is one of the most
likely outcomes of global climate change. The crop addressed is
Indian mustard (Brassica spp.) which is being a C3 plant, is
vulnerable to changes in atmospheric CO2 concentration and
temperature as it is mostly cultivated in tropical and sub-tropical
regions of the world. The differential responses of Brassica
cultivars indicated the selection of RH 30 (B. juncea) as the
better responsive cultivar for future higher CO2 concentration. The
overall characterization of responses of these cultivars to high
CO2 environment suggests a suitable cultivation and nutrient
management system for future climatic condition. The data collected
in the present investigation will help in development of plant type
and model plant for future climate change.
