Climate impacts on crop yields in Central Argentina. Adaptation strategies por Rolla, Alfredo L., Nuñez, Mario N., Guevara, Edgardo Roberto, Meira, Santiago Guillermo, Rodriguez, Gabriel Rodolfo, Ortiz de Zárate, María Inés

“…Projections show an increase in the seasonal means maximum and minimum temperature for both the near (2015–2039) and the far (2075-2099) future, as well as a seasonal annual precipitation increase in the near future and a significant increase in the far future with extreme emissions scenarios. In the near future the crop model projects a reduction in wheat yield, an increase in maize yield and a significant increment in soybean yield compared to the regional baseline for moderate (RCP4.5) and extreme (RCP8.5) emissions. …”
