Water scarcity is becoming more acute, necessitating better understanding of farmer adoption of improved irrigation technologies. Using data from the national 2013 Farm and Ranch Irrigation Survey, this study employs a multilevel modeling approach to analyze irrigation decisions. The variation in pressure irrigation adoption is mainly accounted for by state-level factors, while adoption of scientific scheduling practices is more associated with farm-level factors. Adoption increases with larger acreage, groundwater use, information sources other than neighbors, and recent higher temperatures. Adoption is negatively associated with on-farm surface water and barriers related to increased costs, management time, and time horizon.

Adopting drought tolerant plants (DTPs) to conserve water is a potential adaptation to the predicted effects of climate change in the Midwest. Survey responses from 624 Missouri households were analyzed using a univariate probit model. DTP adoption was positively correlated with both low and high household incomes, living in rural subdivisions, time spent gardening, pro-environment attitudes, and concerns about drought. Policy interventions in newly drought-prone areas might include subsidizing the up-front cost of DTPs, requiring their use in new housing developments so DTPs are the default for buyers, and targeted educational efforts to environmental and gardening groups and rural residents.
