| Summary: | International audience The Inuit of the Canadian North live in isolated territories where there are no land routes. As a result, for the past few decades, they have been facing major adaptation challenges, particularly in terms of food and access to energy. Since June 2016, our research focuses on the potential of greenhouse farming in circumpolar territories with the case study of the cooperative greenhouse of Kuujjuaq (largest village in Nunavik in terms of population - 2375 inhabitants in 2011, latitude 58° north and longitude 68° west). Measurements in this greenhouse revealed a major problem: a temperature difference between day and night that was too large, hindering the development of crops. To address this, a thermal storage system was installed in October 2018. It is based on a rock bed of known porosity, positioned under the crop land, in which a heat transfer fluid that circulates, will allow the daily heat surplus to be stored during period with temperature peak, in order to reheat the greenhouse when the temperature in low, especially in the nighttime. The poster will focus on the performance of the system after two years of operation. Les Inuits du Nord canadien vivent sur des territoires isolés où aucune route terrestre ne permet de se rendre. De ce fait, depuis les dernières décennies ils affrontent de grands défis d’adaptation, notamment sur le plan de l’alimentation et de l'accès à l'énergie. Notre recherche s’intéresse depuis juin 2016 aux potentiels de la serriculture dans les territoires circumpolaires, avec comme cas d’étude la serre coopérative de Kuujjuaq (plus grand village du Nunavik en termes de population – 2375 habitants en 2011, latitude 58° nord et longitude 68° ouest). L’instrumentation de cette serre a permis de mettre en évidence une problématique majeure : un écart de température entre le jour et la nuit trop important, gênant le développement des cultures. Pour y répondre, un système de stockage de chaleur a été mis en place en octobre 2018. Il est basé sur un lit de roche ... |
