To address these issues, we developed novel programs integrating technical instruction and preparation for professional practice in hydrology for cohorts of graduate students from Morocco and Egypt (2012–2013) and from Türkiye and Indonesia (2013–2014). Students participated in an initial online course and a follow-up workshop featuring geographic information systems (GIS), remote sensing, and hydrologic modeling with internet-based data sets. Field activities in the USA (first cohort) and in the students’ home countries (second cohort) included stream gauging, measurement of water levels in wells, water sampling, and measurement of hydrochemical parameters. A subsequent online course focused on research ethics, preparing proposals and publications, and presenting findings to technical audiences and the public, culminating in presentations at conferences in the USA. Participants mentored other students at their home institutions and at K-12 schools in Türkiye and Indonesia. Participant feedback during and after the programs tended to be strongly positive, and participants have continued to engage with project leaders and mentor students in their home countries and the USA. Our modular, hybrid approach offers a template for students in hydrology and related fields to develop relevant skills and engage internationally.</p></div>","PeriodicalId":45920,"journal":{"name":"Journal of Contemporary Water Research & Education","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/j.1936-704X.2024.3409.x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142169943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The bivariate sample selection model controls for the bias in the statistical estimates that occur because producers who volunteer for an irrigation survey are likely to know about and use irrigation more than the population. We find that peer influence operates through multiple irrigation practices, and peer influence through an irrigation practice depends on an irrigator's location and current farm practices.

However, less is known about the application of WBE in rural settings or in areas of limited resources. Most WBE programs in low-resource communities have occurred outside the United States. To reap the benefits, WBE would need to be tailored to better reflect the socioeconomic challenges, technical barriers, communication limitations, and variable wastewater infrastructures associated with rural communities. The objective of this review is to evaluate the potential opportunities and challenges of deploying the current SARS-CoV-2 monitoring methodologies in small, rural communities, with a particular focus on rural Texas. For this, we conducted an inventory of rural communities in the state of Texas and their wastewater infrastructure. Based on specific rural examples, we evaluated the potential of current WBE methodologies used in urban settings to monitor for emerging biological agents of concern such as SARS-CoV-2. Our findings include an overview of rural wastewater capacity across rural Texas, a look at current WBE efforts to detect SARS-CoV-2, and recommendations for future implementation in two cities in rural counties, Kerrville and Valentine. WBE is a rapidly evolving public health tool with several notable advantages associated with cost, access, and adaptability. It is of particular use in resource-limited communities that often exhibit healthcare disparities. This study presents the first overview of the feasibility of implementing WBE in the rural settings of Texas. We provide several recommendations and suggest alternatives that may be of use when planning an expansion of WBE into these areas.</p></div>","PeriodicalId":45920,"journal":{"name":"Journal of Contemporary Water Research & Education","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/j.1936-704X.2024.3406.x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141488455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, exploring the critical nexus between water usage and agricultural yield, can foster academic growth and holds the key to addressing global food security in an era of increasing environmental constraints, where students can unlock insights crucial to enhancing crop yield and sustainability. Investigating the intricate relationship between water management and crop productivity through undergraduate research is exemplified in this article. Undergraduate students acquired hands-on research experience by collecting, processing, and analyzing destructive (crop biomass samples) and non-destructive (plant height, nodes, and leaf chlorophyll content) cropping system data on soybeans under irrigated and dryland production systems, where they worked closely with the farmer. Identifying the current research problem and study site selection, scientific decision-making during the field study, developing critical thinking while ensuring research communication skills, and quality assurance and quality control through technology during data collection and analysis were learning outcomes. The research highlights the observed distinct performance between irrigated and non-irrigated soybeans using non-destructive plant health and growth indicators with plant biomass, following appropriate quality control and assurance steps. Statistically, irrigated soybeans outperformed non-irrigated soybeans in terms of average plant height at maturity (irrigated: 97.0±1.7 cm vs. non-irrigated: 37.4±0.6 cm; p&lt;0.01) and number of nodes on the mainstem (irrigated: 19.5±1.2 vs. non-irrigated: 12.6±0.8; p&lt;0.01).

To determine if a relationship exists between land use/land cover and changing stream flows in northwest Arkansas, this study analyzed temporal changes in various flow statistics for 14 stream gages and compared the rates of change in flow statistics from gages on streams with watersheds that have varying land uses, i.e., urban, agricultural, and undeveloped. Mann-Kendall analysis was used to determine statistically significant changes in flow statistics, which were then compared to National Land Cover Dataset (NLCD) watershed land uses from 2001 and 2019. All analyzed gages had one or more flow statistics with at least a moderately significant increase, and all analyzed flow statistics showed at least moderately significant streamflow increases at two or more gages (P &lt; 0.100). There were no decreases of any significance in any flow statistic at any gage. In general, urban land development did not happen on native prairies and forests but on previously agricultural land. Significant positive relationships were found between maximum yearly flow and 2019 urban land use, urban land use change from 2001 to 2019, and 2019 Human Development Index (HDI). A similar relationship was found to exist between yearly minimum flow and 2019 HDI.

Within this broader interest, the journal also puts value on publishing manuscripts from undergraduate research projects, class projects, and honors thesis with a focus on water research and education. The challenge with these types of manuscripts is the focus and depth should be narrow, time and resources are often limited (e.g., one semester or the equivalent of a 3 student credit hours), and peer-reviewed publication is often not the common standard nor goal for undergraduates (Fenn et al. <span>2010</span>). The latter might be the most pressing challenge, unless the undergraduates have an interest in pursuing advanced degrees, particularly graduate school where the students will be doing research for theses and dissertations. Undergraduates need opportunities like this to frame their water research within broader scientific literature (Fox et al. <span>2017</span>), especially if the next step in their career is graduate school.</p><p>The faculty advisors, mentors, and teachers also play an important role in pushing these types of undergraduate manuscripts forward, while maintaining the undergraduates as the lead author. Faculty can look at publishing undergraduate research with students as the lead authors as an innovative educational opportunity in water resources (Habib and Deshotel <span>2018</span>), explaining how coauthors are selected and ordered, how to craft a readable story in science (e.g., see Mackay <span>1995</span>), how you handle the peer-review process, and how to write acknowledgements.
