Climate change and drought: a risk assessment of crop-yield impacts
Open accessAbstract
We assessed the drought risk for world crop production under current and future climatic conditions by using an integrated approach to analyze the correlation between historical crop yield and meteorological drought.Future drought frequencies are estimated based on ensemble results from 20 general circulation model (GCM) climate change patterns and 6 emissions scenarios from SRES (Special Report on Emissions Scenarios) using a revised Palmer Drought Severity Index.The drought risk index was established by combining the effects of drought-disaster frequency, drought severity, production (yield) and extent of irrigation.Results indicate that, for most regions, the probability density functions (PDF) of the 120 drought disaster frequency projections for 2100 show quasi-normal distributions and consistently project higher drought disaster frequency (DDF ) than that of baseline, which indicates an overall enhanced drought risk in the future climate change.Globally, the drought disaster-affected area will increase with the rising global temperature, from 15.4 to 44.00% by 2100.The average cropland drought risk index (DRI) doubles from 52.45 to 104.60 in 2050 projections.In 2100, the projection for the DRI increases to 129.40.Among the regions, Africa is ranked as the highest, with a baseline DRI value of 95.77 which increases to 205.46 in 2100 projections.Correspondingly, the rates of yield reduction related to drought disaster for major crops will increase significantly with future climate change, by > 50% in 2050 and almost 90% in 2100 for the major crops.Adaptation measures to avoid aggravated drought-disaster risks are called for.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
