Dehcho Collaborative
on Permafrost

Dehcho Ełehéh Ndéh zhı́eh Tę k’eh Eghálagenda

Overview of the Project

Climate warming and human disturbance in the Dehcho region of the Northwest Territories (NWT), Canada, has led to widespread permafrost thaw and land cover change that has disrupted the hydrological cycle and the ecosystems and human activities that depend on it.


There is a growing awareness in the Dehcho that permafrost thaw is negatively affecting the region's economy, and the health, well-being and livelihoods of its residents.


There is lack of information on permafrost distribution, evolution, and resultant landscape change trajectory in this region.


There is an urgent need to develop and mobilise knowledge on permafrost thaw in the Dehcho and elsewhere in the subarctic, develop new, practical and customised predictive tools and strategies to adapt to permafrost thaw, and to provide interactive training to decision makers and other users.


In direct response to this need, the Scotty Creek Research Station (SCRS) and the Dehcho First Nations (DFN), co-propose the Dehcho Collaborative on Permafrost (DCoP), a Dehcho-wide initiative whose overall objective is to generate a fusion of leading-edge scientific and Indigenous knowledge on permafrost, and to use it as a basis to co-develop new predictive decision support tools and innovative risk management strategies to inventory and manage permafrost and adapt to permafrost thaw.


Close consultations with Indigenous communities throughout the Dehcho, identified the urgent need for sustained community engagement based on two-way knowledge exchange to guide specific needs for improved permafrost thaw monitoring, adaptation, process understanding, and prediction. These needs collectively form DCoP's “five themes”, each with specific objectives.



Why is DCoP Needed?

The ~150,000 km2 Dehcho region in the southern NWT is one of the most rapidly warming on Earth. It is also experiencing an increase in direct human disturbance due to expanding industrial activity. Permafrost thaw in the Dehcho is widespread and occurring at unprecedented rates, evidence that this region is particularly sensitive to climate warming and disturbance due to thaw.


Permafrost thaw is disrupting the Dehcho’s land, water and therefore human activities, the patterns, rates, controls and mechanisms of permafrost thaw, and associated feedbacks and land cover transformations across the region remain poorly understood. As a result, there is an urgent need to investigate thaw-induced changes to the Dehcho’s land and water, develop and mobilise knowledge on these changes, develop predictive modelling tools, and provide interactive training to decision makers and other stakeholders.


Although there is a growing awareness throughout the Dehcho that permafrost thaw is negatively affecting the region, regulatory authorities, resource management boards, and communities are ill-equipped to respond effectively to this new and growing challenge because there exists little or no permafrost thaw monitoring, adaptation or predictive capacity in the region, and therefore no appropriate basis for decision support.


In direct response, the Dehcho First Nations (DFN) and the Scotty Creek Research Station (SCRS) co-propose the Dehcho Collaborative on Permafrost (DCoP) to improve the understanding of and ability to predict and adapt to permafrost thaw. Because livelihoods in the Dehcho are so tightly connected to “the land”, DCoP’s close collaborative approach that places Indigenous communities in leadership positions, is required to generate the new knowledge, predictive capacity and decision-support tools needed to manage the land and water resources that support Dene ways of life.


Co-Developed Questions for Research:

Close consultation with Indigenous communities throughout the Dehcho identified six broad research questions:

Q1: Where is permafrost located within the Dehcho and where is it thawing?

Q2: What is the rate and pattern of permafrost thaw?

Q3: How is permafrost thaw changing land?

Q4: What adaptation and mitigation measures can or should be taken?

Q5: How is permafrost thaw changing the flow and storage of water on the land?

Q6: What is the long-term trajectory of thaw-induced change to the land and water?

It is clear from these consultations that the concerns over permafrost thaw and its effect on the land, water and livelihoods are shared throughout the Dehcho.


Co-Developed Themes & Objectives:
Theme 1

Co-develop with Indigenous communities, new initiatives for improving the monitoring (Theme 2), adaptation (Theme 3), understanding (Theme 4), and prediction (Theme 5) of permafrost thaw and its impacts in the Dehcho.

Objective 1

Gather and synthesise the Indigenous Knowledge pertaining to permafrost and permafrost thaw in the Dehcho, and compile this information into the Permafrost Resources.

Objective 2

Gather and synthesise all new knowledge arising from Themes 2-5, and add it to the Permafrost Resources.

Objective 3

Mobilise throughout the Dehcho the Permafrost Resources assembled in O1 and O2 through community engagement in support of themes 2-5.


Theme 2

Improved Monitoring.

Objective 4

DCoP will produce permafrost probability maps as a first step toward defining the current distribution of permafrost in the Dehcho, and establish an Indigenous community-led network to monitor changes to permafrost using both conventional temperature-based and new (DCoP-developed) ice-content monitoring probes.

Objective 5

DCoP will use 2018 imagery to map the current spatial distribution of permafrost, and archived photos (1970) to assess the change in permafrost distribution over the intervening 48 year period.


Theme 3

Improved Adaptation.

Objective 6

DCoP will develop and test new knowledge-based permafrost thaw adaptation strategies designed to lessen the impacts of such thaw, improve safety on the land and in communities, and safeguard infrastructure.


Theme 4

Improved Process Understanding.

Objective 7

Develop new knowledge on the permafrost thaw processes, rates and patterns causing the changes observed in Theme 2 with a focus on critical lateral thaw of discontinuous permafrost.


Theme 5

Improved Prediction.

Objective 8

Share, apply and interpret new methods for predicting the rate, pattern and impact of permafrost thaw customised for specific conditions within the Dehcho.
