Julian R - Vulnerability analyses progress CIAT April 2012 Julian R - Vulnerability analyses progress CIAT April 2012 Presentation Transcript

  • Flora Mer, Patricia Moreno, Carlos Navarro, Julián Ramírez
  • Wheeler 2012. NCC.
  • The approach
  • Modelling changes in crop suitability • EcoCrop: how does it work?It evaluates on monthly basis if thereare adequate climatic conditionswithin a growing season for …and calculates the climatic suitability of thetemperature and precipitation… resulting interaction between rainfall and temperature…
  • Input dataModel training• Present-day climates from WorldClim• Crop distribution data (GBIF, other sources)• An idea of the crop’s ecology, its distribution, and growing season duration• Some literature reviewModel projection• 24 different climate models (2030, SRES-A1B), to sample uncertaintiesAdaptation strategy testing• Genetic adaptation by broadening ecological ranges
  • Preliminary analyses (~2009)Average projected % change in suitability for 50 crops, to 2050
  • Sorghum
  • Cassava
  • New analyses: 26 crops + maize
