Abstract
Sugarcane (
Saccharum
spp.) is main cash crop through-
out the tropical regions of the world. It represents an
important food and bioenergy source, being cultivated
in many tropical and subtropical countries, and covering
more than 23 million hectares worldwide, with a produc-
tion of 1.6 billion metric tons of crushable stems. This
crop is responsible for almost two thirds of the global
sugar production.
The predicted outcomes of climate change in the Indian
context include a rise in temperature, decreased rainfall,
altered rainfall patterns, floods, drought, waterlogging
