Investigating the use of public food forests in urban food systems planning

Public food forests can be an important way to increase urban resilience, sustainability, and food security. The food forest, or forest garden, is an edible landscape designed for food production. This research investigates how publicly-accessible urban food forests are currently being utilized to enhance food production and resilience. By reviewing existing examples, this research seeks to identify key models for design, participatory decision-making, and ongoing management of food forests on public land.

Unpaved forest roads as a source of suspended sediment in the Honna River watershed

The Honna River is the drinking water source for the Village of Queen Charlotte (pop. 950), and is also important salmon habitat. Sediment from unpaved forest roads near the river may be entering the channel in significant quantities, reducing water quality. In two previous internships, intern David Reid implemented a channel reach-scale study of all sediment sources in the Honna River in an effort to collect data regarding the quantity of sediment contributed from the road, and also regarding how this quantity compares to natural sediment sources.

Capacity Building for Competitiveness in Aboriginal forestry

This project recognizes the significant business challenges First Nations forestry enterprises face which have the effect of limiting the benefits to First Nations from forests (Wellstead and Stedman 2010). There is limited awareness of the conditions that affect the success and failure of Aboriginal enterprises in the forest sector (Trosper et al 2008).

Vulnérabilité des forêts et des activités forestières aux changements climatiques

Les feux de forêts naturels sont les perturbations majeures à la base de la dynamique végétale boréale. Les changements climatiques induiront une augmentation des régimes de perturbations. Les régimes de perturbations, la structure et la composition forestière pourraient se diriger vers une variabilité naturelle différente de celle connue précédemment.

Développent d’outils innovateurs pour la caractérisation du bois et de la fibre du bois et leur impact sur la rentabilité financière des travaux d’aménagement forestier intensif

L’aménagement forestier intensif est parmi les alternatives pour assurer la pérennité des ressources pour l’industrie forestière. Cependant, peu d’information est disponible sur les effets de ces pratiques sur la qualité du bois et la valeur des produits. Ce manque d’information est dû à la nature destructive des essais de caractérisation des propriétés du bois. Ainsi, ce projet vise à développer des outils rapides et non destructifs pour mesurer les implications des pratiques d’aménagement forestier intensif sur les indicateurs de la qualité du bois et sur la valeur des produits.

Mycorrhizae in Salmon Forests

Salmon are an iconic and economically valuable species whose life history bridges both the sea, where they live as adults, and inland waterways where they spawn. Their yearly migrations and subsequent deaths fertilize the forests, and signals of this subsidy can be seen in vegetation, insect and bird life. What has been little studied, however, are the below-ground dynamics of this seasonal nutrient flux.

Opportunités durables dans la bio-économie basée sur l’utilisation de la biomasse Boréale perturbée

Le projet de recherche sera réalisé sur le site de Muskrat Falls, le nouveau barrage électrique situé au Labrador. Ce projet rendra disponible, d’ici 2016, 450 000m3 de bois coupés en prévision de la construction du réservoir hydraulique. Le projet de recherche constitue à réaliser des études technico-économiques et environnementales (analyse du cycle de vie) sur l’utilisation de ce bois dans un procédé de bioraffinage. De plus, le projet permettra d’inclure dans les modèles économiques et environnementaux, le bois perturbés de la région de Goose-Bay (feu, insectes et vent).

Analytical chemistry method development for lignin breakdown products

The partner organization MetaMixis Inc. is attempting to use biocatalytic ways to process lignin, the second most abundant biopolymer on earth, with microbiology methods to transform lignin into fine chemicals in useful quantities within a reasonable time frame. The process and end products need to be fully characterized using analytical tools to ensure the efficiency. The end products include vanillin, vanillic acid, p-coumaric acid, syringaldehyde, syringic acid, and vanillyl alcohol.

Multiproxy reconstructions of mixed-severity fire dynamics in the Alberta Foothills

The proposed research will use a multiproxy fire history approach to reconstruct wildfire history, severity, and impacts, as well as controls on and changes to the fire regime in the Alberta Foothills region. Fire scar and stand origin records will be used to reconstruct the fire history of the study area over recent decades and centuries. These records will be extended in length using the macroscopic sedimentary charcoal record.

Further development of sulphite-based dissolving pulp production

The requested Mitacs-Accelerate Internship application will support Dr. Yishan Liu (as an intern) and Dr. Yonghao Ni (as supervisor) of the University of New Brunswick and Neucel Specialty Cellulose. The overall objectives of the project are: 1) to improve the quality of dissolving pulps; 2) to decrease the manufacturing costs by using low-cost wood material. The improvements in pulp quality will be achieved based on enzymatic/ mechanical treatments that can be readily implemented at the existing mill configurations.
