ABSTRACT:
These scripts show the detailed methods that were used for the data presented in McCarthy et al. (2020). The manuscript illustrates results and explains potential mechanisms fueling energy and emissions changes in the High Plains Aquifer portion of the HPA. This analysis looks at water use from 1994-2016, a time where Kansas saw a large shift in irrigation technologies from predominantly high pressure center pivots to lower pressure center pivot variants such as Low Energy Precision Application (LEPA). End result of the code is a series of comma separated .csv files containing the location, energy source, direct energy from pumping, energy footprint from pumping and greenhouse gas emissions of the Kansas portion of the HPA from 1994-2016. This dataset pulls from various sources, described in the readme.md file below. Mainly, data from Water Information Management & Analysis System (WIMAS) was processed and expanded to serve our energy calculation purposes. Main inputs from this dataset include well location, irrigation system type and water use. A series of irrigation scenarios were then conducted on the processed dataset to observe potential energy savings: Observed irrigation and energy source shift, static irrigation and observed energy source shift, static irrigation and energy sources, and observed irrigation and static energy source shift. A detailed analysis of these results can be found in the main manuscript.
