Vertical Agriculture Coming to Carcross

A vertical agriculture facility is in the planning stages with the goal of having it built in Carcross this fall. This innovative project will be the first  of its kind in the Yukon.

Tami Grantham, Natural Resources Coordinator with the Carcross-Tagish First Nation, says:  “What attracted us to this technology is the ability to grow greens year-round. It’s a goal and a mission for the government of Carcross-Tagish First Nation to become food-secure.”

Construction would be managed through a new corporation created as a partnership between the Carcross-Tagish First Nation and Northstar Agriculture of which the First Nation will be 51 per cent owner.

The system will recirculate water from a fish tank through a vegetable grow bed. Nutrients from the fish waste feed the plants, and the plants filter the water to keep the fish healthy. In normal aquaculture, excretions from the animals being raised can accumulate in the water, increasing toxicity. In an aquaponic system, water from an aquaculture system is fed to a hydroponic system where the by-products are broken down by bacteria into nitrates, which are utilized by the plants as nutrients, and the water is then recirculated back to the aquaculture system.

The vertical part of this type of farming will be in the form of stacked layers that could be up to 10 meters high, in order to maximize production, contained in a warehouse-style space.

Not only would this mean a possibility for fresh local produce and lower food prices in the community, but also the promise of food security, as this system allows year-round growing of vegetables in a sustainable way.

The fish raised would be Tilapia, which is common in farming systems. Vegetables grown would include kale, spinach, and perhaps even strawberries and other vine crops.
