“…The most relevant parameter values in the model are summarized in Table 2. Elevations in Sunflower County range from 100 feet above mean sea level (fsl; North American Vertical Datum 1988, NAVD) in the south to 145 fsl in the north (FEMA, 2010) and average surface elevation of 118 fsl (McGuire et al, 2019). Initial aquifer parameters are averaged from publicly available USGS potentiometric maps (McGuire et al, 2019).…”

Tran et al (2020) assumes 29% return flows from irrigation water applications in nearby areas in Arkansas but we employ a more conservative 10% return flow from irrigation.…”

We explore the economic merits of on-farm water storage with tailwater recovery systems to reduce aquifer depletion in a region with expanding irrigated acreage and substantial off-season precipitation. Gains are substantial on a broad scale and long planning horizon, including more than $4 billion in producer surplus, 5 million acre-feet of conserved groundwater, and land capitalization of $24 per acre. Sensitivity analyses provide insights with respect to the impact of discount rates, rainfed returns, return flows, and aquifer recharge rates. Results can inform stakeholders about the optimal allocation of funds directed at agricultural practice adoption and agricultural water investments.

“…This highlights that the solution for basinwide problems may need to be addressed locally in a coordinated manner. The map of Potentiometric Surface of the Mississippi River Valley Alluvial Aquifer published by the U.S. Geological Survey (USGS) for the Spring 2016 [43] shows the location and gradient of the aquifer's cone of depression, indicating that there is a great variability in the aquifer conditions in the region-see Figure 1.…”

Irrigation Water Management Tools and Alternative Irrigation Sources Trends and Perceptions by Farmers from the Delta Regions of the Lower Mississippi River Basin in South Central USA

et al. 2022

View full text Add to dashboard Cite

This article describes the opinions and perceptions of farmers on water management tools that conserve groundwater and on alternative sources of water for irrigation. The analysis is based on a survey of producers (N=466) across the Lower Mississippi River Basin (LMRB) areas of Arkansas, Louisiana, Mississippi, and Missouri. Summary statistics of practice usage across the region and for each state are presented. A Poisson count model is applied to the data to identify factors that influence the number of groundwater-conserving practices employed. The number of irrigated acres, years of farming, annual income level, perception of groundwater problems, and participation in conservation programs have statistically significant association with the number of practices employed. Years of farming experience is the only factor negatively associated with the number of practices employed, while participation in conservation programs has the largest magnitude effect on that number. These results provide evidence that sponsored conservation programs increase the number of conservation practices adopted by farmers. This insight is useful for producer collectives, policy makers, and program managers to design and target of conservation programs across the LMRB.

“…where p e is the price of the energy source for the power unit, d is depth to water used as a proxy for pumping lift, and θ e is the amount of energy from source e needed to lift a cubic meter of water a distance of one meter. The distance to water was obtained from the U.S. Geological Survey [25] based on the respondent's claimed county of residence. Average energy prices were obtained from the U.S. Energy Information Administration (EIA).…”

“…The U.S. Geological Survey (USGS) has recently published a map of the Potentiometric Surface of the Mississippi River Valley Alluvial Aquifer for the Spring 2016 [25] that shows the location and gradient of the aquifer's cone of depression. A cross-tabulation of farmer perceptions and their location in the center of the cone of depression is presented in Table 5.…”

Adoption of Water-Conserving Irrigation Practices among Row-Crop Growers in Mississippi, USA

et al. 2020

View full text Add to dashboard Cite

This article identifies irrigated row-crop farmer factors associated with the adoption of water-conserving practices. The analysis is performed on data from a survey of irrigators in Mississippi. Regression results show that the amount of irrigated area, years of education, perception of a groundwater problem, and participation in conservation programs are positively associated with practice adoption; while number of years farming, growing rice, and pumping cost are negatively associated with adoption. However, not all factors are statistically significant for all practices. Survey results indicate that only a third of growers are aware of groundwater problems at the farm or state level; and this lack of awareness is related to whether farmers noticed a change in the depth to water distance in their irrigation wells. This evidence is consistent with a report to Congress from the Government Accountability Office (GAO) that recommends policies promoting the use of: (1) more efficient irrigation technology and practices and (2) precision agriculture technologies, such as soil moisture sensors and irrigation automation.
