| The vulnerability of cane and sucrose production to climate change and three adaptation options that could be adopted in Mauritius (20.25oS, 57.5oE) were assessed using the Sugarcane module of the Agricultural Production Systems SIMulator (APSIM-Sugarcane). Long-term observed climate data for one location, identified as being representative of the island's productivity, were used to generate the baseline yields that were close to the 1954 to1996 recorded average. Climate change scenarios under a doubling of atmospheric carbon dioxide level were generated using long-term observed data either with outputs from General Circulation Models (increases in temperature with differences in rainfall and radiation patterns), or with nominal increments of 2oC and 4oC rise in temperature with 10 per cent and 20 per cent increase or decrease in rainfall. The direct effects of CO2 fertilization on the physiology of the crop were not accounted for. Under all scenarios, the model simulated a reduction in productivity that was attributed to lower water use efficiencies and higher respiratory demands. Irrigation was the best adaptation option evaluated as opposed to a change in cultivar or harvest date. | |
