Climate change and carbon emissions are top of mind due to the COP21 conference in Paris. It’s also a timely topic of discussion for many Canadians, and especially Albertans, given the provinces’ recently released Climate Change plan.

COP21 (known less colloquially as the 2015 Paris Climate Conference) is the 21st international conference on climate change. The conference boasts attendance of 190 countries, each of which are trying to reach collective agreement on limiting the impact of climate change. To the point, delegates are attempting to agree on ways to prevent the planet from warming more than two degrees by 2100.  

Often when we see and hear about climate change its impacts are conveyed through water—time lapses showing receding glaciers, miserable images of drought, and footage of coastal communities under threat. While water is a universal resource that all people can use to relate to the impacts of climate variability and warming, it remains secondary to energy in climate talks, and is often approached as a sub-section to an overall carbon focus.

Most importantly, the integral relationship between climate and water means the commitments from COP21 will have impacts on how we manage water. For Albertans the commitments starting to flow out from COP21 might, at first, not seem directly relevant to our water management. However, the global focus presents opportunities to share, learn, and refine prevention and mitigation strategies, especially around extreme weather events including flood and drought, and the challenge of water scarcity.

Here are some key topics in COP21 and examples of how they relate to water:

Greenhouse gas emissions

It is no secret Canadians are some of the most wasteful people when it comes to how water is used. Furthermore, this is bad news for greenhouse gas emissions.

For example, before water reaches a home or business in Canada it must be extracted, treated, transported and, once it has been used it, must again be transported, treated, and released. Every one of these steps takes energy. To achieve this, municipalities typically spend between 25 and 60% of their budgets to supply energy for their city’s water infrastructure [1].

Local reuse could help to reduce water use; however, treating domestic and industrial wastewater also creates significant greenhouse gas emissions. For example, the treatment of used household water from cooking, washing, cleaning, and sanitation alone accounts for 3% of global electricity consumption and 5% of global non-carbon dioxide greenhouse-gas emissions (mainly methane). Methane’s comparative impact to carbon dioxide is more than 25 greater over a 100-year period, making it quite the nasty emission [2].

Solutions aren’t easy to come by, and require a mixture of prevention, mitigation, and conservation, to reduce overall greenhouse gas emissions for water usage.

Some say an easier win would be reducing greenhouse gas emissions produced through the production, transportation, and waste created through bottled water, as estimates reveal producing bottled water requires as much as 2,000 times the energy cost of producing tap water [3]. A little ironic considering popular bottled water brands like Dasani and Aquafina are essentially tap water treated for aesthetics.

With water scarcity (and therefore quality) linked to water treatment, and water treatment linked to energy, it will be interesting to see if COP21 addresses these relationships to water in the current or future climate talks.

Sustainable agriculture and forestry

At COP21, a panel is considering sustainable agriculture, forestry, and their use of water. These competing demands for the world’s most valuable resource are referred to as the Water Energy Food Nexus.

Agriculture is one of the sectors most seriously affected by climate variability but it also accounts for 24% of greenhouse gas emissions, which cause climate change [4]. It makes sense to break this futile loop, and water conservation and smart technologies for agricultural water use could be the biggest circuit breaker. When it comes to water, agriculture consumes 70% of freshwater used by humans, much of which is sourced from non-renewable aquifers [5]. Improved monitoring and expanded regulation could improve this number.

The forestry industry has growing awareness of the need to consider watershed management as a tool for developing plantations that focus on forest productivity, as well as environmental and social benefits, mainly in terms of maintaining water supply and water quality to downstream users [6]. The industry is also questioning local watershed impacts including erosion, flood, and fire implications.

Emission tradeoffs

Similar to greenhouse gas emissions, as soon as tradeoff conversations become more detailed, water becomes an implicit consideration. Take hydraulic fracturing for example: at an Alberta Water Conversation event in 2013 attendees largely agreed that fresh water should not be used for fracturing and that saline water would be a better choice. However, questions quickly arose on where saline water is located in relation to a well, and the transport implications of shipping saline water, or the energy required to create fresh water from a saline water source. This shows how quickly emissions tradeoffs and water become complicated.

Ultimately, decisions in climate impact water and decisions in water impact climate. To address these issues, communities and decision-makers are increasingly taking a holistic approach to these systems, not only trying to prevent global warming, but introducing ways for communities to adapt to the increasing climate variability that is forecast around the world, including in Alberta.

At COP21, the United Nations say it themselves, “Adaptation to climate change is closely linked to water and its role in sustainable development.” [7] Water may not be the headline from COP21, but it will be a clear indicator of how effective actions from the conference, and how effective subsequent regional or local initiatives will be, against the targets set.

Recent significant floods and the predicted increase of extreme weather events have many Albertans, from insurance experts to governments to property owners, talking about flood insurance.

Throughout these conversations the same basic, but tough, questions continue to rise. We don’t know all the answers, but here are the questions as they relate to the current situation and developments.

 

1. How do you define a flood?

Is a flood a specified volume down the closest river? Overland water only? More than five basements flooded in one community? Groundwater infiltration? When a provincial disaster is declared?

The Insurance Bureau of Canada states that in general, overland flooding resulting in water entering a home is not covered. Overland flooding usually occurs when bodies of water, such as rivers, dams, and other watercourses, overflow onto dry land and cause damage.[1]  

There are also differences for insurance between flood damage and water damage.

What is clear is that consensus on the definition of a flood would enable consistency in policy development, education, and coverage levels for the large number of stakeholders impacted by flood insurance including the Alberta public. Once a flood is defined, you can narrow down what can and can’t be covered in the event of damage.

 

2. Who owns flooding risk?

When floods subside there’s usually plenty of finger pointing on what could’ve been done, who’s responsible, and what needs to be done to avoid the damage of future floods. However, the crux question is who owns the risk?

If we look at an existing house on a floodplain, there were multiple parties involved throughout the steps leading to the development, approval, construction, purchase, insurance, and renovations or other property work. Because there are so many diverse stakeholders and circumstances it’s unlikely there will ever be a single body, or owner, responsible for flood risk (or its management) in Alberta.

So, if there isn’t one owner of the risk, it has to be shared – and how that works is yet another question! Looking around the world it’s common for flood risk to be shared across levels of government, private insurance companies, and individual householders. This would require a strong collaborative and inclusive approach to developing flood risk and management in a province like Alberta.

However there’s more to that challenge, as how people work together is influenced by their own perception of a particular issue. When it comes to risk, in many cases, people’s perception is often to underestimate it.

Programs like Disaster Financial Assistance Arrangements (DFAA) have also impacted people’s perception of risk, building an expectation for some people that someone else, like the government, should cover the costs of their loss. In theory the government has obligations to support the public; however this approach exposes all taxpayers to large costs in the event of a disaster and potentially undermines private insurance efforts.

To revisit the question of who owns flooding risk, there needs to be a balanced distribution of risk between government, private sector, and homeowners. How that could work for Alberta will take some time to develop.

3. How do you cost flooding risk?

After you decide how flooding risk is dispersed, there has to be a common value to disperse it – and that’s usually financial. However, it’s not as easy as divvying up costs. Cheap insurance can reinforce risky choices of where and how to reside. At the other end of the scale, expensive insurance precludes many people who want to cover their property for damages but cannot afford to cover it.

One suggestion is insurance pricing reflects flood mitigation measures that have been invested in. For instance, a province spends millions on flood mitigation, and these investments are captured in insurance premiums.

Another complication for pricing flooding risk is that each region is different, and a broad brush approach to pricing would not be suitable. This requires tools, like updated flood mapping and modelling, to support the suitable pricing of risk across different locations.

Additionally, flood mapping and modelling needs to be adaptable, as changing infrastructure (such as flood mitigation) would have an impact on insurance pricing. This creates an obstacle for insurers and municipalities to overcome on the timely communication of infrastructure changes that may influence insurance premiums.

 

4. Should the province or the nation lead changes in flood insurance?

Since every provincial assistance program is different, a ‘one size fits all’ approach would be difficult. Also, eliminating programs like the DFAA is not a black and white decision at the federal level, let alone considering provincial implications.

Further, the government can, and has, introduced regulatory prevention strategies (similar to Ontario where development on flood plains is not allowed), but the insurance industry must also be involved heavily in leading the change and educating the public in a clear way on what flood insurance means.

5. What’s being done at the moment?

In Alberta

Across Canada

Public Safety Canada is working with the Insurance Bureau of Canada in exploring a ‘Canadian solution’ to the problem of overland flooding. Work is starting up again now the federal election is over.

Public Safety Canada is also collaborating with Environment Canada and Natural Resources Canada to identify national standards on flood mapping. In addition they will be learning from the United Kingdom and Germany to inform Canada’s approach.

A private sector working group has been established for the insurance industry to collaborate on the challenges faced in the development of flood insurance in Canada.

 

6. What can I do to protect myself now?

We suggest the following resources to get you started:

Further information and support may also be available via your local community or municipality. For example in Chestermere (Alberta) a group has formed in response to the July 2015 floods. Their goal is to better understand and respond to some of the emotional impacts of the flood, and to source and provide access to resources to support residents, no matter the level of impact on their lives.

Flood insurance in Alberta won’t be here overnight, but a number of providers are starting to offer overland flooding options for property owners.

Flood insurance is not as simple as offering policies to everyone. Updated flood mapping and risk assessment of flood prone areas, improved land-use planning, public education and awareness, and investments in mitigation are all required as part of an effective approach. By asking simple but hard questions, it’s clear the issue is not just an insurance topic and any approach to changing the situation needs to be an inclusive one.

 

This blog was informed and inspired by a Stakeholder Discussion - Residential Flood Insurance session, facilitated by Public Safety Canada and the Insurance Bureau of Canada in Calgary earlier this month.

Government of Alberta budget overview

On 27 October the Government of Alberta released their budget. We've summarized the key water-related elements in a  pdf budget overview. (401 KB)

 

High River flood mitigation projects and Disaster Recovery Program changes announced on 2 November

Further to the announcements on 26 October outlined below, on 2 November the province announced $30 million in multi-year funding for the Town of High River flood mitigation projects. Funded projects include:

  • Design and construction of the southwest berm
  • Design and construction of the 5th Street berm
  • Lineham Bridge rehabilitation, and
  • A working group to assess upstream and downstream impacts of the planned flood defences (this group will be supported by an additional $2 million for flood modeling).

The decision was made not to build a diversion for High River due to concerns about environmental sustainability and cost effectiveness.

Representation on the working group will come from the province, Town of High River, Municipal District of Foothills, and the Highwood Management Plan Public Advisory Committee.

Changes were also announced for the Disaster Recovery Program (DRP):

  • The government will cease collection on overpayments for files of $5,000 or less (affecting nearly 550 outstanding case files).
  • In about 75 cases where overpayments are more than $5,000, files will be handled on a case-by-case basis.

·         The government will be closing nearly 450 files that are classified as inactive (applicants will be contacted before the close out). 

26 October announcements

On 26 October the Government of Alberta announced a range of flood mitigation projects, and ongoing funding of $150 million over ten years, to help protect communities along the Elbow River and Calgary from a repeat of the costly 2013 flood. Here's the list of work announced and briefly what it means.

1. Springbank Off-stream Reservoir chosen over other options including McLean Dam

McLean Creek Flood Storage (McLean Dam) is off the table, and the Glenmore Diversion (also known as the Calgary flood tunnel or “the aqueduct”) is on the shelf. 

Working in tandem with the Glenmore Reservoir, the Springbank Off-stream Reservoir aims to provide protection for a 2013-level flood on the Elbow River. During floods a canal would carry water from the river to the off-stream reservoir (capacity 70.2 million cubic metres). After floods the excess water would be returned to the Elbow River.

2. Localized Mitigation for Bragg Creek and Redwood Meadows

Dikes and drains in Bragg Creek with protection to 2013 level with freeboard (an extra level of protection above the base flood elevation).

Redwood Meadows’ work will be determined after Bragg Creek, as Redwood Meadows is downstream of Bragg Creek.

3. Bow River Working Group

A stakeholder representative group tasked with providing assessment on future flood protection along the Bow River. It is expected this group would continue existing collaborative Bow River group work undertaken to date.

4. Five River Hazard Studies

This work involves the production of new flood inundation and flood hazard maps for the Bow, Elbow, Sheep, Highwood, and Peace Rivers.

What’s next?

The announcements signify a breakthrough for flood mitigation action in, and upstream, of Calgary. However it's no secret there’s a lot of work to be done. The announcements have also triggered many questions surrounding the operation of the Springbank Off-stream reservoir including:

  • Would the Glenmore Reservoir or Springbank Off-stream reservoir be filled first?
  • What cues will prompt the flood and compensate model to be deployed?
  • How quickly will the reservoir be drained, keeping in mind groundwater flows?

Numerous questions have also popped up around what’s happening for people impacted by flooding in areas along different rivers, or in different watershed basins, and if the River Hazard Studies will involve traditional flood mapping or other techniques.
