    “When rainfall fails and evaporative demand climbs, root-zone soil moisture is where the deficit registers first and where it carries forward, weeks before crop condition reflects it. In this study [link above], [the authors] used SMAP root-zone soil moisture to forecast crop productivity anomalies across drought-prone croplands of Eastern and Southern Africa, and [they] quantified how much predictive value soil moisture actually carries, over what lead times, and under which hydroclimatic conditions. The contribution of soil moisture was negligible at short leads but grew steadily out to 40 days, and it concentrated in water-limited croplands where soil moisture and vegetation are most tightly coupled. During the 2024 southern African El Niño drought, the soil moisture informed model resolved the spatial pattern of productivity anomalies roughly a month in advance.
    Beyond the results themselves, this work is a pointer to how much predictive information soil moisture holds. Leveraging the temporal record of SMAP-related products together with the 100–200 metre resolution NISAR will deliver gives us, [believes the H/T], a clear path to attempt field-scale drought forecasting in the smallholder landscapes where early warning matters most…”

  3. There we go with a bit of an #introduction as I might be migrating from Twitter.

    I am a #palaeoecologist, that is someone who studies ecological processes over time (sometimes, very deep time). Some words are #resilience #fireecology #communityecology #stability #climatechange #globalchange #EasternAfrica #Iberian #mountains #Quaternary #biogeography #restoration

    Aside of that, I love mixing art and sicence #scicom #drawing walking in #nature #swimming madly #cooking and #crochet.
