Managed Aquifer Recharge (MAR) is a promising approach to enhance water supply resilience, but it faces significant challenges, such as limited space and time for recharge activities, well uncertain bio-geophysical processes, complex subsurface flow heterogeneity. In this review, we assess the viability of hydrology-based approaches groundwater replenishment identify missing components in existing recovery activities. We discuss expanding opportunities under-utilized sources locations...
To examine public support for organizations that aim to control or prevent aquatic invasive species (AIS), we assessed social-psychological factors influence residents' intentions AIS using a survey of residents in Minnesota, USA. We found the two dimensions value orientations – biocentric and anthropocentric have differential impacts on risk perception response efficacy. also intention is influenced by their belief effectiveness actions. Based these findings, recommend targeted...
Agricultural fertilizer contributes substantially to nitrogen pollution throughout the world, leading many negative impacts including ecological dead zones. Alternative crop management practices, such as cover crops and perennial crops, can limit pollution. To optimize land use changes meet potential nitrate reduction scenarios, we develop a flexible geo-spatial economic framework, balancing with reductions in farm profit. Cover patterns at hydrologic response unit (HRU) level are simulated...
As climate change, population demands, and economic growth put increasing pressure on finite water resources in the southwestern United States, there is a critical need for adaptation to scarcity region. The Water Adaptation Techniques Atlas (WATA) new web-based compendium of geospatially-referenced solutions problems posed by scarcity. Developed USDA Southwest California Climate Hubs, WATA arranges these as case studies pinpointed an interactive, user-friendly map viewer. Cases include...
We estimated willingness to pay for local aquatic invasive species lake management in the form of a daily access fee by conducting summer surveys Minnesota, USA. Similar pairs lakes with differing infestations zebra mussels, Dreissena polymorpha , and starry stonewort, Nitellopsis obtuse were used as study sites infer how being at an infested vs. uninfested different would impact responses. also examined recreationists’ visit motivation, perceived risk, knowledge, awareness problem. mean...
Abstract Irrigated agricultural lands in arid regions often suffer from soil salinization and lack of drainage, which affect environmental quality productivity. Integrated Farm Drainage Management (IFDM) systems, where drainage water generated higher‐valued crops grown on high soils are used to irrigate salt‐tolerant marginal soils, is one possible strategy for managing salinity problems. If the IFDM crop were a biofuel crop, both private benefits may be generated; however, little known...
In California, Brassica oilseeds may be viable crops for growers to diversify their cool-season crop options, helping them adapt projected climate change and irrigation water shortages. Field trials have found germination establishment problems in some late-planted canola, but not camelina at the same locations. We used computer modeling analyze fall seedbed conditions better understand this phenomenon. seedbeds too dry, cold, or both, support of canola during late fall. Based on...
During California’s severe drought from 2011 to 2017, a significant shift in irrigated area annual perennial crops occurred. Due the time requirements associated with bringing maturity, more acreage likely increases opportunity costs of fallowing, common mitigation strategy. Increases fallowing may put additional pressure on another “go-to” strategy—groundwater pumping. Yet, overdrafted groundwater systems worldwide are increasingly becoming norm. In response depleting aquifers, as evidenced...
Several ways to address the looming ecological disaster that is Salton Sea have been proposed — including water importation. Here we considered two options: importing ocean from of Cortés and leasing agricultural users in Imperial Valley. We estimated monetary costs for compared with transferring Sea. found agriculture would be substantially cheaper than imports. Additionally, all infrastructure growers exists, which means transfers could begin immediately. That important given present...
Abstract Replacing corn crops with perennial species can decrease sedimentation, increase soil health metrics, and of particular importance for the reduction dead zones downstream, reduce agricultural nitrate pollution. Farmers be paid to grow species, but how much they are willing accept do so, as well what factors influence amount want, key. Using a mail survey administered 3,000 farmers in Minnesota, home headwaters Mississippi, we show that higher trust environmental organizations state...
