"Climate Change Impacts on Winter Road System and Remote Indigenous Communities" with Yukari Hori

When and Where

Monday, March 29, 2021 4:00 pm to 5:00 pm


Yukari Hori, PhD, Department of Physical and Environmental Sciences, University of Toronto Scarborough


A network of winter roads in northern Canada connects a number of remote Indigenous communities to all-season roads, rails, airports, and marine ports. The extent of the winter road networks depends on the geographic features, socio-economic activities, and the numbers of remote communities so that it differs among the provinces and territories. For many of these communities, winter roads provide not only the transport of heavy equipment, fuel, and cargo at a low cost, but also expand social and cultural opportunities in the communities. However, the impacts of climate change on winter roads have become a significant concern; for example, a warmer climate has resulted in a shorter winter road season and an increase in unreliable road conditions. Thus, limiting access among remote communities. In this talk, Dr. Hori will provide the climate change impact assessment that her team has conducted for winter road networks in northern Ontario and the south of the 60th. She will also introduce her recent project to develop a user-friendly and open-access web-based portal for winter roads in Canada’s Territorial North.

Speaker Bio

Dr. Yukari Hori is a Research Associate at the Department of Physical and Environmental Sciences, University of Toronto Scarborough (UTSC), and she is also a member of the CL@UT. She received her Ph.D. degree in the Department of Physical and Environmental Sciences at UTSC with the Environment and Health collaborative program at the School of the Environment, University of Toronto. Yukari’s major research interests are the impacts of climate change on northern environments and the wellbeing of remote Indigenous communities in the Arctic and subarctic regions. Her research uses a multidisciplinary approach which includes climatology, environmental science, and Indigenous knowledge about climatic and environmental changes on winter road infrastructure in northern Canada.

This is a School of Cities Seminar Series "Building Resilience in Food and Health Supply Chains"

Supply chains are the primary societal infrastructure for the production, delivery, and recycling of goods and services. Though sometimes invisible, supply chains are the systems that ensure that flour is available in your grocery store, that hospitals have sufficient personal protective equipment, and that there are enough trained staff to administer medical tests, deliver babies, and check-out your groceries. While much of the effort in supply chains over the past 50 years has been to make them agile, fast, and cheap, there is a growing realization that supply chains must be able to adapt to disruptions from local events such as the inability for a plane to land due to weather to global changes such as the closing of the US-Canada border due to COVID-19.

This seminar series seeks to develop a multi-disciplinary understanding of resilient supply chains by examining two which are of critical importance to everyday life: food and health supply chains. The talks in this series look at these supply chains, both independently and together, through the inclusion of diverse speakers representing at least the following perspectives:

  • Supply Chain Optimization 
  • Northern and Remote Food and Health Security
  • Urban Food Systems
  • Systems of Food Production
  • Healthcare Systems
