“…These results are similar to those reported by Da Silva et al. (), who forecasted increases of up to 13% in the production of sugarcane in Brazil and Australia under year 2070 scenarios. Singels, Jones, Marin, Ruane, and Thorburn () similarly reported future yield increases of +9% in dryland sugarcane in Brazil and 20% in South Africa.…”

Assessments of impacts of future climate change on widely grown sugarcane varieties can guide decision‐making and help ensure the economic stability of numerous rural households. This study assessed the potential impact of future climatic change on sugarcane grown under dryland conditions in Mexico and identified key climate factors influencing yield. The Agricultural Land Management Alternatives with Numerical Assessment Criteria (ALMANAC) model was used to simulate sugarcane growth and yield under current and future climate conditions. Management, soil and climate data from farm sites in Jalisco (Pacific Mexico) and San Luis Potosi (Northeastern Mexico) were used to simulate baseline yields. Baseline climate was developed with 30‐year historical data from weather stations close to the sites. Future climate for three decadal periods (2021–2050) was constructed by adding forecasted climate values from downscaled outputs of global circulation models to baseline values. Climate change impacts were assessed by comparing baseline yields with those in future decades under the A2 scenario. Results indicate positive impacts of future climate change on sugarcane yields in the two regions, with increases of 1%–13% (0.6–8.0 Mg/ha). As seen in the multiple correlation analysis, evapotranspiration explains 77% of the future sugarcane yield in the Pacific Region, while evapotranspiration and number of water and temperature stress days account for 97% of the future yield in the Northeastern Region. The midsummer drought (canicula) in the Pacific Region is expected to be more intense and will reduce above‐ground biomass by 5%–13% (0.5–1.7 Mg/ha) in July–August. Harvest may be advanced by 1–2 months in the two regions to achieve increases in yield and avoid early flowering that could cause sucrose loss of 0.49 Mg ha−1 month−1. Integrating the simulation of pest and diseases under climate change in crop modelling may help fine‐tune yield forecasting.

By 2050, the world population is likely to be 9.1 billion, the CO2 concentration 550 ppm, the ozone concentration 60 ppb and the climate warmer by ca 2°C. In these conditions, what contribution can increased crop yield make to feeding the world?CO2 enrichment is likely to increase yields of most crops by approximately 13 per cent but leave yields of C4 crops unchanged. It will tend to reduce water consumption by all crops, but this effect will be approximately cancelled out by the effect of the increased temperature on evaporation rates. In many places increased temperature will provide opportunities to manipulate agronomy to improve crop performance. Ozone concentration increases will decrease yields by 5 per cent or more.Plant breeders will probably be able to increase yields considerably in the CO2-enriched environment of the future, and most weeds and airborne pests and diseases should remain controllable, so long as policy changes do not remove too many types of crop-protection chemicals. However, soil-borne pathogens are likely to be an increasing problem when warmer weather will increase their multiplication rates; control is likely to need a transgenic approach to breeding for resistance. There is a large gap between achievable yields and those delivered by farmers, even in the most efficient agricultural systems. A gap is inevitable, but there are large differences between farmers, even between those who have used the same resources. If this gap is closed and accompanied by improvements in potential yields then there is a good prospect that crop production will increase by approximately 50 per cent or more by 2050 without extra land. However, the demands for land to produce bio-energy have not been factored into these calculations.

“…In elevated CO2 concentration only Sugarcane is a recognized efficient crop in terms of greatest increase (Fig. 17) in sugar production and Productivity [63,31], expands leaf area, dry weight of leaf and stem and juice volume [69], rises nitrogen use efficiency, intake of light and water and high water use efficiency [70], increases biomass production (16), large decrease in crop transpiration (-11.0 and -10.5 %) and evapo-transpiration (-9.1 and -8.9 %) in sugarcane occur at increasing CO2 concentration at 750 ppm [34], and also sugarcane mitigates the CO2 emissions emitted from soil [18].…”

Worldwide increasing demands of food, fodder, fuel and other bio-chemicals for erratically increasing population, urbanization and industrialization. Only sugarcane (Saccharum spp.) has great potential as a major feedstock for sugar, biofuel and allied related production. Sugarcane is the lead driver for production of sugar and sweeteners globally. It is considered among the best options and replace the fossil fuels for production of biofuels today due to an exceptional biomass production capacity, high carbohydrate (sugar + fiber) content, and a favourable energy input/output ratio. The conversion of sugarcane biomass into fermentable sugars for second-generation ethanol production is a promising alternative to meet future demands of biofuel production in the world. Biofuels have gained much importance due to the depleting fossil fuel resources and the over-accumulation of CO2 and other greenhouse gases in the environment. Biofuel and paper production from sugarcane can be achieve the targets to replace fossil fuels to scavenge carbon dioxide released into the atmosphere and to attain environmental and economic sustainability. Fermentable sugars (40-60%) of molasses which is diluted with distilled water and by fermentation process (Saccharomyces cerevisae) produce rum (wine). Application of sugarcane by-products, such as press mud, vinasse and bagasse, to improves chemical, physical, and biological properties of soil and enhanced the crop quality and yield. For transfer the live micro-organism from agar slant of laboratory to rhizosphere then sugar press mud play key role in formulating microbial inoculant as suitable carrier. Food yeast Torulopsis utilis, is prepared from molasses used as baker’s and brewer’s yeast in bakery industry. Sugarcane improves the economy of rural population by providing lead source of fodder for livestock management as a sugarcane tops and by-products of sugarcane (molasses treated with urea, mineral mixture treated sugarcane top hays etc.). Scientific interventions have not only helped to improve the cane crop but industrial procedures have also been upgraded resulting in improved production of biofuel, paper, wine etc and other sugarcane by-products used to improve the economy of rural and urban population. However, building a bridge between science and industry requires investments in research, development and transfer of new technologies to the industry as well as specialized personnel to deal with new technological challenges.
