| Abstract | The Standardized Precipitation Index (SPI) characterizes meteorological droughts of a place, by quantifying the deficit of rainfall in different time periods. Negative SPI values represents drought, while positive values indicate wet periods. The results suggest that negative SPI periods coincide with El Nino years: 82-83, 91-92 and 97-98. The 91-92 event had the largest impact on the region. These results indicate that the most severe droughts in the basin of Dagua, were presented at the quarters of Dec- Jan-Feb, Jan-Feb-Mar, Jun-Jul-Aug and Jul-Aug-Sep. The results have been obtained with geostatistical techniques, and are a basic input to formulate adaptation strategies and ensure food sovereignty of small farmers against drought. |
