Abstract: Sugarcane is one of the most important industrial crops in global agriculture and it has come out as a multi-product crop profiting producers and consumers. Sugarcane provides about 80% of the global sugar production and it is cultivated in more than 90 countries encompassing nearly half of the world for both sugar and bioenergy. It is a C4 plant (i.e the first stable product of CO2 fixation is 4 carbon compound) belongs to the family, producing high biomass compared to any other cultivated crop. Its stem is considered as the most useful economic product globally accounting nearly 80% for sugar production. For the low productivity of sugarcane many more biotic and abiotic factors are responsible. Moreover, to meet the persistent high production of sugar per unit area under the changing climatic regime, adoption of abiotic stress tolerant varieties with climate smart agronomic practices becomes indispensable. Among agronomic manipulations for the management of abiotic stresses, breaking soil compaction barrier using appropriate machinery and cultivating tolerant sugarcane varieties, scheduling irrigation based on cumulative pan evaporation, conserving soil moisture by way in-situ trash mulching, green cane trash blanketing using sugarcane harvesters and trash shredding machineries and use of soil amendments such as composted coir pith, bulky organic manure and application potassium and micronutrients through foliar sprays and usage of appropriate energy efficient machinery for ratoon crop management are important. In this chapter, the various strategies are discussed for sustaining the sugarcane production under climate change scenario.
