1 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 Principal Scientists Graciela Magrin, INTA, ArgentinaGraciela Magrin, INTA, Argentina María I.

2 Project Premise prepared and adapt to possible climate change scenarios better cope with current climate variability 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

3 CLIMATE VARIABILITY in the Pampas Region ENSO and other sources

4 CLIMATE and VARIABILITY Example: Climatology in La Estanzuela, Uruguay Mean Rainfall in EELE ( ) MONTH

5 Monthly Rainfall in EELE MONTH Example: Observed Monthly Rainfall CLIMATE and VARIABILITY

6 Example: Monthly rainfall in 12 years (La Estanzuela) Monthly Rainfall in EELE MONTH MEAN None of the years shows monthly rainfall similar to the long-term values Still, planning is based on long-term values (Probability  0) CLIMATE and VARIABILITY

7 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

8 Oct-NovNov-DecDec-JanJan-FebFeb-MarMar-Apr Chance of having precipitations higher (blue) or lower (red) than normal during "El Niño" and “La Niña” years. "El Niño" “La Niña”

9 Differences in three-monthly Precipitation (mm) and Maximum Temperature (ºC) During “EL NIÑO” and “LA NIÑA” years.

10 Probability of having high yields (blue) or low yields (red) during El Niño and La Niña years.

14 ENSO-related Forecasts are Poor in January and February Pantanal: 150,000 km 2 of Wetlands

15 Sources of Interannual Climate Variability other than ENSO Correlation Between Rainfall in November in the Pantanal And Rainfall in Jan-Feb in SE South America r = 0.6 – 0.8

16 South Atlantic SST impacts on summer precipitation and crops yield Soybean Yield SST-SA (May) and Precipitation (January + February)
