Query Tools

Note: This data set has now been superseded by a new data set on the effects of climate change on global food production under SRES emissions and socio-economic scenarios produced by the same authors. Users are recommended to use the new data instead. SEDAC is maintaining this web site for reference purposes.

The following query tools are designed to help users answer questions of the data set resulting from the crop-climate modeling study. As a general rule, the questions can be grouped into three subsets (as follows), with their related query building tools (in the box below):

  • How dependent are crop yields on specific scenarios? (see Query 1 and Query 3)
  • Are climate change vulnerability and adaptation different for each crop? (see Query 2)
Sample outputs are provided to give you a sense of the kinds of results you can expect from each type of query. Click on the image in each sample output box to see an enlargement.
 
Query 
Sample Query 
Sample Output
1.  I'm interested in one particular country or region. I want to know what how specific scenarios of climate change, CO2 effects and farmer adaptation will impact crop yields in that country or region. (Choose this.) Show me yield changes in Australia for the three equilibrium climate change scenarios (GISS, GFDL & UKMO) with CO2 effects but without adaptation. Sample output - Query 1
2.  I'm interested in one particular scenario, and would like to see what the impact of this scenario would be on yields for the four commodities in all BLS countries and regions. (Choose this.) Show me the impact of the GISS equilibrium scenario, with CO2 effects and level 1 adaptation, on the yields for all commodities in all BLS countries and regions.

Sample output - Query 2

3.  I'm interested in one particular crop commodity, and would like to see how it is affected by specific scenarios of climate change, CO2 effects and farmer adaptation in different regions. (Choose this.) Show me wheat yields in 2050 for all BLS countries and regions under the CM3-A, CM2-S550, and CM2-S750 climate change scenarios, without CO2 effects and with level 1 adaptation. Sample output - Query 3
