Building capacity to assess the impact of climate change/variability and develop adaptive responses for the mixed crop/livestock production systems in the Argentinean , Brazilian and Uruguayan Pampas • Principal Scientists • Graciela Magrin, INTA, Argentina • María I. Travasso, INTA, Argentina • Osvaldo Canziani, Argentina • Gilberto Cunha, Brazil • Mauricio Fernandes, Brazil • Agustin Gimenez, GRAS- INIA, Uruguay • Walter E. Baethgen, IFDC, Uruguay • Holger Meinke, APSRU, DPI, Australia
Project Premise One of the most effective manners for assisting agricultural stakeholders to be prepared and adapt to possible climate change scenarios, is by helping them to better cope with current climate variability
CLIMATE VARIABILITY in the Pampas Region ENSO and other sources
CLIMATE and VARIABILITY Example: Climatology in La Estanzuela, Uruguay Mean Rainfall in EELE (1915-2000) MONTH
CLIMATE and VARIABILITY Example: Observed Monthly Rainfall Monthly Rainfall in EELE MONTH
CLIMATE and VARIABILITY Example: Monthly rainfall in 12 years (La Estanzuela) Monthly Rainfall in EELE MEAN None of the years shows monthly rainfall similar to the long-term values Still, planning is based on long-term values (Probability 0) MONTH
Currently planning for conditions that will not exist (Probability = 0) Can we plan for conditions with Probability > 0 ? Improve Planning and Decision Making RESEARCH PROJECTS INIA – INTA - IFDC
