Drought

“A two-stage stochastic planning model for western Kansas irrigators under self-imposed 5-year pumping caps beat both actual farmer decisions (2013–2022) and average-rainfall deterministic planning, especially in dry years. Tighter pumping limits favor shifting from corn to sorghum and saving water in early years to spend later; stretching the allocation window past about 7 years adds little extra profit.”

“The Palmer Drought Severity Index has been widely used to evaluate drought conditions since it was developed in 1965. In the original formulation of the PDSI, potential evapotranspiration (PET) was estimated using the Thornthwaite equation. This study evaluates how using more physically based approaches for estimating PET influences the depiction of drought conditions over the U.S. Great Plains from 1980 to 2012.”

“High temperature extremes cause fire occurrence and burned area to increase nonlinearly.”

“Standard soil health frameworks built around raising organic matter in humid regions don't transfer well to arid and semi-arid Great Plains soils, where low rainfall caps SOM gains; dryland assessments need indicators tied to water-related functions instead. Gains in soil health indicators are largest when practices are stacked — reduced tillage plus residue retention, organic amendments, and more diverse, intensified rotations — rather than adopted singly.”

“Soil microbiomes play a key role in driving biogeochemical cycles of the Earth system. As drought frequency and intensity increase due to climate change, soil microbes and the processes they control will be impacted.”
