Water Insighes Seminar - Intensification of Wastewater Treatment for Nutrient Removal and Resource Recovery

Management of the N cycle has been identified as one of the Grand Challenges in the 21st century by the National Academy of Engineering, highlighting needs for further research using integrated management approaches. In a wastewater treatment plant, aeration accounts for about 40-60% of energy consumption for organic C and N removal. Innovative technologies are necessary to reduce the energy consumption in wastewater treatment and recover resources from waste streams.

Promise and Peril in Participatory Approaches to Water Quality Research

Dr. Jackson-Smith is a rural sociologist who uses social science research tools and collaborations with interdisciplinary teams to study the human dimensions of complex agricultural and environmental change. His work often involves participatory approaches that engage stakeholders directly in the design, conduct, and analysis of scientific research and modeling.

Sharing Lessons Learned: Creating an interdisciplinary team and using a nexus approach to address a resource hotspot in San Antonio, Texas

San Antonio is home to a rapidly urbanizing population, with major agricultural activity surrounding the city, and a growing production of oil and natural gas in its underlying Eagle Ford shale play. The region of San Antonio represents a resource hotspot whose stakeholders compete across sectors for the same limited water, land, and financial resources and whose projection trends indicate continued growth across those sectors.

Understanding Water-Energy-Food Nexus Hotspots: Holistic Multi-faceted Assessments with Localized Solutions

The challenge of meeting increasing water, energy, and food needs is linked not only to growing demands globally, but also to the tight interdependence of these interconnected resource systems. Proposed interventions to address these challenges must be multi-faceted and need to acknowledge the multiple dimensions of the biophysical water, energy, and food systems, as well as the multi-sectoral actors connected with them. Whether policy, technological, or social interventions are considered, these need to be localized and contextualized.

Water Insights Seminar - Water for Agriculture: Implementing and Assessing Collaborative Resource Management

Stakeholder engagement has been touted as an effective means to address difficult natural resource challenges. Engagement has the promise of creating more effective long-term solutions by bringing local and scientific knowledge and allowing resource managers to collectively define and champion solutions. How-ever, these outcomes are far from certain, are resource and time intensive, and require expertise not always available to organizations tasked with addressing resource issues.

Water Insights Seminar - Soil Health Related Research and Practice Implementation at Stroud Water Research Center

Stroud is working with the PA No-Till Alliance and Steve Groff of Cover Crop Coaching to provide outreach, training, and mentoring/technical advising to producers who are transitioning to soil health focused farming systems. Additionally, Stroud staff are working with 2 individual producers to implement hundreds of acres of new cover crops and multi-species cover crops in the White Clay Creek Watershed where extensive long term monitoring is in place and positioned to evaluate watershed scale outcomes of the implementation.
