متن کاملForages and Pastures Symposium: assessing drought vulnerability of agricultural production systems in context of the 2012 drought.
Weather and climate events and agronomic enterprise are coupled via crop phenology and yield, which is temperature and precipitation dependent. Additional coupling between weather and climate and agronomic enterprise occurs through agricultural practices such as tillage, irrigation, erosion, livestock management, and forage.

متن کاملAssessing Agricultural Drought in the Anthropocene: A Modified Palmer Drought Severity Index
In the current human-influenced era, drought is initiated by natural and human drivers, and human activities are as integral to drought as meteorological factors. In large irrigated agricultural regions with high levels of human intervention, where the natural farmland soil moisture has usually been changed significantly by high-frequency irrigation, the actual severity of agricultural drought ...
