When people use freshwater beyond a physically sustainable rate, it sets off a cascade of impacts on ecosystems, people and the planet. These impacts include groundwater wells running dry, fish populations becoming stranded before they are able to spawn and protected wetland ecosystems turning into dry landscapes. Developments in computer models and satellites have fostered a new understanding of how freshwater is being redistributed around the planet and have made clear the central role that people play in this change. This human impact is so significant that organizations like the United States Geological Survey are redrawing their water cycle diagram to include the impacts of human actions.
P.E.I. environment officials consider creating water-use buffer
P.E.I. environment officials are mulling whether to create a water-use buffer given that farmers will be able to apply to construct more high-capacity wells under the province's impending irrigation strategy. Currently, regulations allow groundwater wells to draw down a waterway by 35 per cent of a stream's base flow in August and September. But Bruce Raymond, manager of water and air monitoring at the Department of Environment, Energy and Climate Action, says officials are weighing whether to only permit 90 per cent of that draw down.
