The world faces difficult choices between diverting finite water resources for agricultural and municipal useand maintaining the integrity of aquatic ecosystems. Irrigation is essential for the economic prosperity ofCanada's agricultural industry, and our growing cities require increasing quantities of fresh water. However, thequantity, quality, and timing of the water in our rivers must also be maintained to sustain aquatic ecosystems.This research will explore groundwater use, healthy stream maintenance, and environmental watermanagement, as well as societal division on these issues. Studies will examine full-scale groundwaterextraction from seven Prince Edward Island (PEI) watersheds for agricultural irrigation and city water supplies.The study will evaluate potential impacts of water extraction on stream flow and life in a changing climate, aswell as possible benefits of irrigation, including reduced fertilizer use though better nutrient management,healthier soil mediated by increased organic matter, reduced greenhouse gas emissions from soil, and increasedeconomic prosperity. Effects on the soil, groundwater, streams, and stream-dwelling fish and invertebrates willbe observed. Set within the context of PEI's new Water Act, this work will evaluate how science, regulation,and social values can be synergized to enable improved knowledge-informed governance. The outcomes willhave many benefits to Canadians, including improved methods to understand stream flow that consider climatechange, ways to biologically test whether stream flow regulations are working, advanced soil nutrientmanagement strategies involving supplemental irrigation, better ways to increase soil organic matter to reducewater needs, and the incorporation of broader thinking into regional environmental management, includinginclusive participation and engagement. Together, these outcomes will provide crucial information that willhelp Canada move toward water sustainability.

世界面临着将有限水资源用于农业和市政用途与维护水生生态系统完整性之间的艰难选择。灌溉对于加拿大农业产业的经济繁荣至关重要，而且我们不断发展的城市需要越来越多的淡水。然而，我们河流中的水的数量、质量和时间也必须得到维持，以维持水生生态系统。本研究将探讨地下水的利用、健康的河流维护和环境水管理，以及这些问题上的社会分歧。研究将考察从爱德华王子岛 (PEI) 的七个流域全面抽取地下水用于农业灌溉和城市供水。该研究将评估在气候变化下抽取水对溪流和生命的潜在影响，以及灌溉可能带来的好处，包括通过更好的养分管理减少化肥的使用，通过增加有机质来改善土壤健康，减少土壤的温室气体排放，以及增加经济繁荣。将观察对土壤、地下水、溪流以及溪流中栖息的鱼类和无脊椎动物的影响。在爱德华王子岛新水法的背景下，这项工作将评估科学、监管和社会价值观如何协同作用，以改善知识型治理。研究结果将为加拿大人带来许多好处，包括改进考虑气候变化的了解溪流的方法、生物学测试溪流流量调节是否有效的方法、涉及补充灌溉的先进土壤养分管理策略、增加土壤有机质以减少水需求的更好方法，以及将更广泛的思维纳入区域环境管理，包括包容性参与和参与。总之，这些成果将提供重要信息，帮助加拿大实现水资源可持续发展。
