Changes in global water supply hint at future conflicts, crises

Globe and Mail / Ivan Semeniuk / 16 May 2018

By combining 14 years’ worth of satellite data, scientists have captured a startling portrait of the world’s water supply undergoing rapid transformation. The new analysis points to areas where there is increasing potential for conflict as a growing demand for water collides with the impacts of climate change. In Canada, the maps shows shifting water supplies that include wetter, more flood-prone regions in many areas of the country but a general drying out in the western sub-Arctic.

“This is an eye-opener,” said Roy Brouwer, an economist and executive director of the University of Waterloo’s Water Institute who was not involved in the analysis. “It raises awareness that things are changing and that in some areas something has to happen to counter and anticipate some of the catastrophes that may be waiting for us in the not-so-far future.”

There will be floods — and Ontario’s not ready for them

TVO / Tim Alamenciak / 20 February 2018

The audience at the Provincial Flood Forecasting and Warning Workshop sat silently as the rug was pulled out from under them.

Municipal and provincial staff — many of them forecasters and emergency managers — were gathered at a Brampton conference centre to hear Gord Miller, Ontario’s former environmental commissioner, talk about climate change. What he had to say challenged many of the established practices and assumptions that had guided their careers.

His point was this: climate change has altered the fundamentals of the weather system. All of our old predictions — which were used to build thousands of kilometres of road, drainage pipe, and sewers — are inadequate. The changes to the weather system are so profound that old models and methods can’t accurately predict what’s going to happen; new models predict catastrophes so great that preparing for them could lead to bankruptcy.

“I don’t think here in Canada we understand what’s coming,” said Miller during the talk. “We have no predictability any more. One has to look from the perspective that all culverts are undersized. All sewers are undersized.”

Floodplain Mapping Update proposed

City of Brockville / 10 November 2017

Project Description

Review and update floodplain mapping for Buell’s and Butler’s Creeks.

Project Rationale

The City’s creek systems react relatively quickly to rainfall and snowmelt events. There are several areas where homes and businesses are close enough to the creeks to be potentially vulnerable during flooding events. Applying improved mapping technology to a larger database of creek flow records, and taking into consideration recent developments will result in greater accuracy in comparison to the 1997 floodplain mapping. The project would be jointly funded by the City, Cataraqui Region Conservation Authority and Public Safety Canada (conditionally approved through the National Disaster Mitigation Program)

How climate change is already costing you money

TVO / Patrick Metzger / 01 November 2017

It’s been understood for decades that greenhouse gases, produced largely by humanity’s infatuation with fossil fuels, are heating up the planet. However, in spite of 2017’s startling tally of hurricanes, wildfires, and other weather disasters, there remains a widespread misperception — exacerbated by poor media coverage of the climate change connection — that we’re facing a relatively minor problem that won’t hit hard for years, if ever.

This idea is wrong for all kinds of reasons, some of them profoundly alarming. However, even for those so far insulated from the worst of climate-related catastrophe, climate change is already hitting us where it counts — our wallet.

South Nation wants new flood map

Recorder & Times / Wayne Lowrie / 19 September 2017

The South Nation Conservation authority has applied for federal money to map the flood-prone areas along the St. Lawrence River from outside of Cornwall to Brockville.

The money under the National Disaster Mitigation Program would update 25-year-old floodplain maps based on the evidence from this year’s record flooding, according to Sandra Mancini, the authority’s engineering team lead.

She told Augusta township council the mapping would cover the corridor between the 401 and the St. Lawrence River.

Mancini said the survey, done by airplane, would use electronic technology that plots the topography of the strip along the river. The information would allow the authority to map the areas that would be in danger of flooding when the river spills its banks.

Stormwater scorecard added to toolkit

Green Communities Canada / GCNews / Issue 906: August 2017

The updated and redesigned Soak It Up! Toolkit includes a new feature: a Stormwater Scorecard to help communities assess progress to date and identify priorities for further action. GCC developed the scorecard in partnership with the Canadian Freshwater Alliance and the Our Living Waters Network, supported by a grant from Tides Canada and Mountain Equipment Coop.

The toolkit outlines 16 actions municipalities can take to reduce runoff and runoff pollution, provides examples of what communities are doing, and offers insights from practitioners about what works and what doesn’t.

The Transition Framework

What the Transition movement does incredibly well is small-scale experiments which are practical, which resonate with local people, which look as if they’re doable, and that can engage people at a practical and meaningful level. It connects up the big issues and the local issues and shows you that change can happen at a local level.
