"Smallholder farmers in sub-Saharan Africa (SSA) currently grow rainfed maize with\r\nlimited inputs including fertilizer. Climate change may exacerbate current production\r\nconstraints. Crop models can help quantify the potential impact of climate change\r\non maize yields, but a comprehensive multimodel assessment of simulation accuracy\r\nand uncertainty in these low-input systems is currently lacking. We evaluated\r\nthe impact of varying [CO2], temperature and rainfall conditions on maize yield, for\r\ndifferent nitrogen (N) inputs (0, 80, 160 kg N/ha) for five environments in SSA, including\r\ncool subhumid Ethiopia, cool semi-arid Rwanda, hot subhumid Ghana and\r\nhot semi-arid Mali and Benin using an ensemble of 25 maize models. Models were\r\ncalibrated with measured grain yield, plant biomass, plant N, leaf area index, harvest\r\nindex and in-season soil water content from 2-year experiments in each country to\r\nassess their ability to simulate observed yield. Simulated responses to climate change\r\nfactors were explored and compared between models. Calibrated models reproduced\r\nmeasured grain yield variations well with average relative root mean square\r\nerror of 26%, although uncertainty in model prediction was substantial (CV = 28%).\r\nModel ensembles gave greater accuracy than any model taken at random. Nitrogen\r\nfertilization controlled the response to variations in [CO2], temperature and rainfall.\r\nWithout N fertilizer input, maize (a) benefited less from an increase in atmospheric\r\n[CO2]; (b) was less affected by higher temperature or decreasing rainfall; and (c) was\r\nmore affected by increased rainfall because N leaching was more critical. The model\r\nintercomparison revealed that simulation of daily soil N supply and N leaching plays\r\na crucial role in simulating climate change impacts for low-input systems. Climate\r\nchange and N input interactions have strong implications for the design of robust\r\nadaptation approaches across SSA, because the impact of climate change in low input systems will be modified if farmers intensify maize production with balanced nutrient\r\nmanagement."^^ .
