Burgeoning populations are increasing municipal water demand in Colorado, a phenomenon that is changing rural and urban economies. Agricultural water is a preferred source for meeting growing demands, but transfers often require formerly irrigated land to be fallowed, thus removing a key industry from rural regional economies. One alternative to such ‘buy and dry’ strategies that is gaining interest allows farmers to lease a portion of their water portfolio to cities. Water is made available for lease as farmers fallow their land on a rotational basis or reduce the consumptive use of their cropping operations by limiting irrigation. But will farmers adopt limited irrigation strategies if water lease markets materialize? This research considers whether farmers are willing to sign leases if suitably compensated; what remuneration is needed for a farmer to enter into a lease agreement; how much water the farmer will release when compensated; what provisions are desired in a lease agreement; and what characteristics are shared by farmers willing to lease.Research results are useful for policymakers who may need to alter existing institutions so that the transactions costs of leases do not outweigh the potential gains from trade, and for farmers and municipal water providers actively engaged in developing water leasing alternatives.Potential adoption is gauged from a survey of irrigator’s in Colorado’s South Platte River Basin, a basin experiencing significant population growth in the midst of significant agriculture production. The results indicate that more than 60 percent of the respondents are willing to lease, garnering between 50,000 and 60,000 AF of potential water supplies.

The objectives of this study are to: (i) estimate the actual evapotranspiration (ETa) of the different irrigated crops in the South Platte River Basin, Colorado, USA; (ii) compare the consumption use for the irrigated areas for 2001 and 2010; (iii) investigate the impact of irrigation system (flood/sprinkler) on the estimated ETa. The ReSET model, a surface energy balance remote sensing based model, is used in this study to estimate the ETa of the South Platte River Basin irrigated crops for 2001 and 2010. Landsat 5/7 satellite images, weather data, shape files of irrigated crops, and a digital elevation model (DEM) were acquired and processed for the study area. The results of this study show that the estimated ETa using the ReSET model showed a reduction of 7.1% from 2.51 × 109 m3 in 2001 to 2.33 × 109 m3 in 2010, mainly due to the reduction of the irrigated area from 2001 to 2010 by 6.6%. The estimated total ETa of crops irrigated with flood irrigation systems decreased from 66.1 to 54.6%, while the estimated total ETa of crops irrigated with sprinkler systems increased from 33.9 to 45.4%. For 2001, the average seasonal ETa of all crops for flood irrigation and sprinkler irrigation, respectively, were 665 and 712 mm, with a 7% greater ETa for sprinkler systems. The ReSET model ETa estimates have been validated in a previous study of lysimeter measurements. However, in this study and due to the unavailability of a lysimeter, the model ETa estimates were verified with the reference evapotranspiration (ETr) of the weather stations in the study area. The results of the t-test shows a p-value = 0.124, greater than 0.05, which indicates that the means of the ReSET ETa estimates and the ETr are not significantly different. Additionally, the results of the F-test shows a p-value = 0.674, greater than 0.05, which indicates that the two variances of the ReSET ETa estimates and the ETr are homogeneous.

Climate change can have an adverse effect on agricultural productivity and water availability in semi-arid regions, as changes in surface water availability lead to groundwater depletion and resultant losses in crop yield. These inter-relationships necessitate an integrated management approach for surface water, groundwater, and crop yield as a holistic system. This study quantifies the future availability of surface water and groundwater and associated crop production in a large semi-arid agro-urban river basin in which agricultural irrigation is a leader consumer of water. The region of study is the South Platte River Basin (72,000 km2), Colorado, USA. The coupled SWAT-MODFLOW modeling code is used as the hydrologic simulator and forced with five different CMIP5 climate models downscaled by Multivariate Adaptive Constructed Analogs (MACA), each for two climate scenarios, RCP4.5, and RCP8.5, for 1980–2100. The hydrologic model accounts for surface runoff, soil lateral flow, groundwater flow, groundwater-surface water interactions, irrigation from surface water and groundwater, and crop yield on a per-field basis. In all climate models and emission scenarios, an increase of 3 to 5 °C in annual average temperature is projected. Whereas, variation in the projected precipitation depends on topography and distances from mountains. Based on the results of this study, the worst-case climate model in the basin is IPSL-CM5A-MR-8.5. Under this climate scenario, for a 1 °C increase in temperature and the 1.3% reduction in annual precipitation, the basin will experience an 8.5% decrease in stream discharge, 2–5% decline in groundwater storage, and 11% reduction in crop yield. These results indicate the significant effect of climate change on water and food resources of a large river basin, pointing to the need for immediate implementation of conservation practices.
