Enabling the Flow of Ecosystem Services from Agriculture to Improve Puerto Ri...National Institute of Food and Agriculture
This project aims to (1) reduce nutrient losses and nitrous oxide emissions from agriculture in Puerto Rico, (2) increase farmer flexibility and motivation to provide ecosystem services, and (3) develop additional farm revenue streams. The researchers will assess impacts of alternative management practices, quantify ecosystem service credits, identify areas for cost-effective emissions reductions, and estimate a regional supply curve for credits. Field trials will compare nitrous oxide and nitrate impacts of control and reduced nitrogen application rates on plantain crops.Pls tile pres gen
Tile drainage systems are designed to remove excess water from soil to improve crop growth. They work by allowing water to drain through perforated pipes underground and flow to an outlet. Studies show tile drainage can increase crop yields by up to 38% and reduce surface runoff, soil erosion, and movement of nutrients and pesticides. It also benefits the environment by improving soil health, structure, and biological activity. Regulations around tile drainage vary between provinces but generally require notification or permits from local water authorities.

This document describes a project to improve water yields for villages in Tanzania through rainwater harvesting and artificial groundwater recharge. A 1989 water scheme was experiencing declining yields, so from 2006-2014 monitoring and pilots were conducted. A strategy of increasing groundwater recharge through rainwater infiltration was tested. A hillside dam and infiltration pits successfully recharged an estimated 2.5 million liters, increasing dry season yields from 0.3 to 0.8 liters/second. Proper maintenance and community involvement were important to the project's sustainability. While challenges remain, the results demonstrate that rainwater harvesting can significantly improve rural water supplies.Oregon Rain Garden Guide

Using the Vetiver Grass Technology to Protect Shorelines - GolabiSoil and Water Conservation Society
This document discusses the use of Vetiver grass systems to protect water resources from sedimentation and pollution. It describes how establishing narrow hedges of Vetiver grass across slopes can slow rainfall runoff, spread it evenly, and trap sediments. The deep, dense root systems of Vetiver grass also increase soil shear strength and stability. The document provides examples of using Vetiver hedges for various applications like soil and water conservation, slope stabilization, wastewater treatment, shoreline protection, and watershed management. Case studies from Guam and Vietnam demonstrate how Vetiver grass successfully reduced soil erosion and sedimentation in construction areas near water resources.Building Raingardens
The document discusses the benefits and design considerations for building raingardens. Raingardens are shallow depressions planted with vegetation that improve stormwater quality through biological and soil processes. They reduce runoff, recharge groundwater, and remove various pollutants. Key factors in designing raingardens include the watershed size, soil type, utility locations, plant selection, and ensuring proper overflow drainage. Several examples of existing raingardens are also presented.
Tuesday Plenary Panel - Tomer
The document provides an overview of the Agricultural Conservation Planning Framework (ACPF), a database, concept, and GIS toolbox for watershed planning in the Midwest. The ACPF uses data on soils, land use, terrain and other factors to identify opportunities for placing different conservation practices in fields, at field edges, and in riparian zones. It emphasizes a tiered approach starting with improving soil health within fields, then placing water control practices below fields and riparian buffers along streams. The ACPF can help develop planning alternatives to reduce nutrient loads and prioritize practices, but does not make final recommendations, as watershed planning requires local stakeholder involvement.

This study evaluated the relationship between forest cover and water quality in tropical agricultural watersheds in Brazil. The results showed that watersheds with higher percentages of forest cover (>55%) had better water quality, with lower levels of turbidity, nutrients, and bacteria. In contrast, watersheds with larger areas of agriculture and urbanization (<35% forest cover) had worse water quality. The results also indicated that restoration of riparian forest buffers could improve water quality by reducing sediment levels by up to 9% and nutrient levels by up to 22%. The study highlights the importance of maintaining forest cover and implementing best management practices in agricultural and urban areas to protect water quality in tropical watersheds.

This document summarizes research on how ecological practices can mitigate floods and droughts. A meta-analysis found that no-till practices improved infiltration rates by 21% on average, while cover crops improved infiltration by 19% and perennials by 59%. Continuous living covers like cover crops and perennials increased soil water storage by 8-9%. Modeling shows that shifting less profitable cropland to perennials and cover crops reduced runoff 10-14% and increased water usage 7-10%, with larger benefits during droughts. Targeting these practices to high erosion or low profit areas provides flood mitigation and drought resilience benefits.

Baffaut - Multi-Scale Monitoring
This document summarizes research from the Goodwater Creek Experimental Watershed on the effects of no-till and cover crops on water quality. The summary is:
1) No-till and cover crops reduced sediment loss but did not change nitrate transport and increased dissolved phosphorus transport.
2) Multiple factors like land use change, urbanization, and stream processes influence watershed water quality and make it difficult to detect trends or impacts from individual changes.
3) To better detect water quality impacts from management changes, the changes need to be implemented quickly, targeted spatially, of large magnitude, and address the key processes causing water quality issues.

Adapting conservation systems
The document discusses the Watershed Demonstration Project, a joint initiative between USDA-NRCS and Environmental Defense Fund to address water quality issues associated with Midwestern agriculture using a watershed approach. It notes that nutrient reductions of 45% are needed to reduce dead zones and algal blooms. The watershed approach aims to strategically implement practices that reduce and recycle nutrient inputs, manage water flow, and restore buffers and filters across fields and landscapes. It is a voluntary, participatory, iterative process supported by various partners and tools to monitor progress and outcomes.
The watershed approach
This document outlines an innovative watershed approach to reducing nutrient losses from agricultural landscapes. The key points are:
1) Past conservation efforts have successfully reduced soil erosion but more is needed to reduce nutrients like nitrogen and phosphorus. The scale of the problem requires solutions at the watershed scale rather than just the farm scale.
2) By understanding how landscapes have changed and nutrient flowpaths, critical source areas and sink areas can be identified. Restoring sinks on just 1-2% of the landscape can decrease downstream loads by 45%.
3) The watershed approach follows nutrient flowpaths and prioritizes practices to reduce sources, transport, and restore sinks. These may include improved fertilizer management, cover crops
Best management practices verification
This document summarizes a study evaluating the effectiveness of best management practices (BMPs) at improving water quality in the Gully Creek watershed in Ontario. Monitoring and modeling approaches were used to analyze the impacts of BMPs including cover crops, conservation tillage, nutrient management, and water and sediment control basins. Key findings included: 1) Land management BMPs were difficult to monitor but modeling suggested they could reduce sediments, phosphorus, and nitrogen at the watershed scale; 2) A water and sediment control basin was effective at reducing sediments; and 3) Monitoring during high flow events and at more locations is needed to better understand BMP impacts on water quality.

Duriancik - Applying Monitoring Projects
This document summarizes findings from the Conservation Effects Assessment Project (CEAP) Watersheds studies and how they are being used by the Natural Resources Conservation Service (NRCS). Key findings include how certain conservation practices are effective at reducing nutrients in surface runoff but less so in tile drainage, and that over 50% of sediment in watersheds comes from stream sources like banks and gullies. NRCS is using these data to improve conservation planning, targeting, program guidelines, and practice standards to increase effectiveness, especially in addressing phosphorus and sediment losses at the watershed scale.
Lessons learned from the nifa ceap synthesis
This document summarizes lessons learned from the NIFA-CEAP Synthesis and other watershed studies. Key lessons include: (1) Conservation planning must be done at the watershed scale with sufficient water quality and modeling information; (2) Pollutants of concern and their sources must be identified before implementing practices; and (3) Technical assistance to farmers works best when delivered locally by a trusted contact. Effective conservation requires addressing economic, social, and technical factors influencing farmer decision-making. While models and monitoring provide useful information, they also have limitations and must be carefully designed and implemented.

This study investigated concentrated flow paths (CFPs) in agricultural fields in southern Illinois:
- CFPs drained a large percentage (average 81%) of field areas and were the main conduit for transporting sediment and nutrients off-site.
- Field characteristics like organic matter, clay content, slope, and saturated hydraulic conductivity were associated with CFP occurrence and properties, but explained little (1-2%) of the variation observed.
- Further research is needed to better understand the physical processes forming CFPs and how their morphology changes over time to help target conservation practices like riparian buffers.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
