The Alberta Water Nexus: Energy, Food, People
A nexus is the place where points intersect, linking many different parts of a system together. Water is the nexus between food, energy, and people. Water is required to meet the demands of our growing population, to maintain and improve environmental health, and to support the production of food and energy. As the availability of water changes and our population grows, meeting the demands in the Nexus will become increasingly challenging.

Food, energy and people demand water and other resources, and meeting the requirements is challenging due to population growth, economic development, and climate change.
Each sector uses water in different ways and has different priorities. Decision makers in each sector may not recognize their impacts on other water users. Individual and collective decisions made by people and communities have a large impact on the water-food-energy nexus.
Simply stated, our actions and choices result in consequences for our water, food, and energy resources. Try using the Nexus simulator to explore the results of choices in all three sectors in the Bow River Basin in 2030.

Connections across the Water Nexus
Equitably sharing a common resource like water among many users with diverse needs is challenging. In addition, there are multiple connections between sectors making it even more complex. For example, choosing to conserve water by limiting irrigation of crops will drive up the cost of food and many people will lose their jobs. These connections can also mean that multiple sectors benefit from one choice or action. For example, conserving water by taking shorter showers also conserves energy by demanding less hot water.

The Alberta Water Nexus Project
For over three years, the Alberta WaterPortal has been developing and building a project that explores the connections between water, energy, food (the water-energy-food nexus). Because the demand for these resources is driven by people and their decisions, the project also incorporates socio-economic considerations including the ways people are benefiting from balance in the Nexus, and how choices by one group of people impact the livelihoods of others. Although the nexus concept can be explored around the world, the Alberta Water Nexus Project focuses specifically on Alberta.
The crucial question driving the Alberta Water Nexus Project is:
How can available water be managed to support healthy aquatic ecosystems while also ensuring reliable, quality water supplies are available for a sustainable economy and to meet community needs?
For further background on the project and the stakeholder engagement workshop that was held in 2017, please visit the Alberta Water Nexus Project page.
The volume breakdown of water in the Bow River Basin
The Sankey diagram above shows the volumes of the Bow River that are allocated for different uses, as well as the origins of water in the Bow River. The widths of the grey bars are proportional to the flow quantity, and the same total volume of the Bow River is shown in each segmented portion across the graph. It is important to note that the volume of the Bow River changes over time and varies from year to year. This diagram helps us to conceptualize the movement of water throughout the Bow River Basin from its source to end-use, and the complexity of water use in the Nexus.
