Regional Climate Forecast Coupled groundwater, economic and crop models have been developed for studies in the Ogallala Aquifer. The data for these studies have been gathered and stored in GIS data models. Results illustrate crop choices, changes in groundwater elevation, and total revenue.
Assessing Impact of Climate Variability and Climate Change on Crop Production in Ogallala Aquifer Region. Ogallala region will experience warmer temperatures and temporal shifting of precipitation patterns. In future climates, productivity of grain sorghum will decrease, while winter wheat will increase. Crop management decisions and genetic advancements can minimize yield losses.
Evaluating 90-day Forecasts for Cropping Strategies If accurate 90-day forecasts can be developed, then we posses the management knowledge to position crops to reduce the impacts of crop stress on yields.
Understanding Climate Variability for Improving Management Decisions Region would experience 4-6 C increase in the maximum temperature and highly variable rainfall. Variations in minimum temperatures would be more profound with an average increase of 5-7 C. A sharp decline in grain sorghum production; however, wheat showed a significant increase in yield.
Modeling Aquifer Recharge During 2006-2008, we monitored the water budget in ten playas on the Texas High Plains. Seepage rates ranged from 1 to 20 mm/d and varied significantly between locations and inundation events. Playas surrounded by cropland drained an average of four times faster than playas in native grassland.
