Abstract
Changes in water availability have a strong impact on the sustainability and maintenance of agriculture, with water footprint (WF) being a robust methodology to assess these transformations. The Guadalupe Valley is one of the places with the highest agricultural production in Mexico. Despite its semi-arid climatic conditions, it provides high-quality crops that are well-positioned in the world. The historical trend of rainfall and temperatures between 1987-2017 was analyzed with the purpose of identifying climatic patterns in the territory. Through the calculations of the water footprint of Grapevine and Olive crops, the sensitivity of the crops to recurrent water deficit and their adaptation in their yields to drought episodes was identified. The decrease in rainfall and extreme temperatures led to an increase in crop evapotranspiration and crop irrigation requirements. As a result, there has been a clear increase in the consumption of WF agricultural since 2007. Thus, the period of highest WF agricultural consumption was 2014 (Extremely dry), as opposed to 2011 (Very wet). In particular, the lowest WF green consumptions were observed in extremely dry years, that is, >20% of the WF agricultural intensifying drought events. Therefore, these periods were compensated with higher uses of WF blue and WF gray, which are inversely correlated with precipitation, where vine crops consume 73% more WF agricultural compared to olive plantations, showing greater interannual variability. These results contribute to crop diversification, land use planning, water consumption efficiency, and drought risk reduction.

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.
