Current Recruitment Calls
I am currently recruiting MSc and PhD students as well as Post-doctoral Fellows for the following funded projects
Characterizing the carbon footprint of organic crops produced in the Western Canadian, Ontario or Quebec/Maritimes Regions
Funding is available to support three (3) Masters students at a rate of $20,000 annually for two years (plus possible additional paid internship for summer 2020)
Organic agriculture continues to be among the fastest growing sub-sectors of the agri-food industry in Canada and around the world. Currently occupying ~330,000 ha, the production of organic field crops is of central importance in the context of Canadian organic agriculture as well as the production of a wide range of secondary organic products (e.g. breakfast cereal, bread, animal feeds, etc.) derived from field crops.
Organic agriculture is often perceived to be, and promoted as, a climate-friendly alternative to conventional agriculture. However, farm size, production practices, yields and efficiencies can be much more heterogeneous than in conventional agriculture. While some specific organic practices may be relatively climate friendly, others may not be. The implications of this heterogeneity for the greenhouse gas (GHG) emissions of Canadian organic field crops are not well understood. Moreover, a robust comparison of the GHG emissions from organic products to those from conventional, non-organic field crop production systems in Canada, taking into account regionally-specific production conditions and efficiencies, has not been possible to date.
As part of a multi-institutional project aiming to quantify the net GHG emissions for major organic field crops Canada-wide, we are seeking three students, one student each to be enrolled in the:
MSc program based at the University of British Columbia – Okanagan campus under the supervision of Dr. Nathan Pelletier (will assess Western Canadian organic cropping systems),
MES program based at the University of Waterloo under the supervision of Dr. Goretty Dias (will assess Ontario-based organic cropping systems), and
MES program based at Dalhousie University under the supervision of Dr. Peter Tyedmers (will assess Quebec- and Maritime province-based organic cropping systems).
Though based at three different institutions, the students will collaborate closely with each other throughout their programs and additional supports are available to help facilitate this interaction. Using a common approach (life cycle assessment) to characterize farming activities and estimate emissions from both on farm and associated upstream activities (e.g. equipment and fuel production and delivery, nutrient procurement strategies, management of crop residues, etc.), as well as potential sinks of carbon on farms, our study will provide the first, nation-wide profile of greenhouse gas emissions across the organic field crop sector in Canada.
Successful candidates for these fully-funded research-based Masters opportunities will ideally have backgrounds in agriculture and/or agricultural engineering, industrial ecology, or environmental science/studies, and a strong interest in sustainable food systems research. All successful candidates will possess a driver’s licence that is valid in Canada and access to a vehicle would be an asset. Candidates interested in working in Quebec and the Maritime provinces must be functionally fluent in both French and English.
Successful candidates will each begin their respective Masters programs in September 2020. However, they may also be eligible for a paid internship during summer of 2020 to begin data collection prior to formally starting their Masters program.

Implications of Supply Management for Food Security, Food Sovereignty and Environmental Sustainability in the Canadian Egg Industry (Funding: $20,000 annually for 2 years) Commodity egg production in Canada is subject to "supply management." A central marketing agency (Egg Farmers of Canada) oversees quota-based production and marketing of eggs from over 1000 farms distributed across ten Canadian provinces and one territory. Supply management was implemented to prevent "boom/bust" cycles in egg production, and hence promote fair prices and income stability for farmers, and price predictability for consumers. It also has the effect of ensuring geographically distributed rather than concentrated production.
In non-supply management egg industries in other countries, production of eggs and other livestock products are often concentrated in regions where feed inputs are grown. This has the benefit of shortening transportation distances for feed inputs. However, it also implies longer transport distances for livestock products to consumer markets (often involving use of smaller, refrigerated vehicles), as well as, potentially, higher rates of food loss to spoilage. Centralized compared to distributed production may also present different food security and food sovereignty outcomes.
This interdisciplinary MSc project will investigate potential food security, food sovereignty, and environmental benefits and impacts of the supply managed Canadian egg industry relative to a hypothetical non-supply managed production scenario. An ISO-14044 compliant life cycle assessment study will be undertaken to evaluate the life cycle resource use and emissions implications.
Life Cycle Assessment of LED Lighting for Pullet and Layer Barns (Funding: $20,000 annually for 2 years) Lighting systems for livestock production, in particular for poultry, are influential for animal health and productivity (Er et al. 2007; Hassan et al. 2014). Diverse lighting systems have been used in the poultry industry. Most recently, light emitting diode (LED) lighting systems have been developed for poultry housing. These systems are primarily marketed based on their energy efficiency compared to competing lighting systems, which can effect significant cost savings for producers. Several researchers have reported differences in egg weight, shell strength, rate of lay, bird behaviour and feed conversion efficiency under different single and combined monochromatic LED light regimes (Karakaya et al. 2009; Huber-Eicher et al. 2013; Mendes et al. 2013). Carefully selected LED lighting regimes may therefore have important implications for sustainability performance which go far beyond direct, farm-level energy savings. This is particularly true with respect to changes in feed use efficiency, since feed inputs are the largest contributor to supply chain resource use and emissions for egg production (Pelletier et al. 2014), as well as rate-of-lay and mortality rates, both of which influence feed use efficiency. An ISO-14044 compliant life cycle assessment study will be undertaken to evaluate the life cycle resource use and emissions implications of the use of LED lighting in egg production facilities. The student will collaborate with Egg Farmers of Canada staff to identify study sites, liase with farmers, and collect data for key production performance parameters including on-farm energy use, feed conversion efficiency, rate-of-lay and mortality rates on Canadian farms currently implementing a combination of LED and non-LED lighting in parallel layer barn systems. These data will be used to produce life cycle inventory models for egg production using LED lighting for comparison against the national average benchmark model (Pelletier 2017). Scenario models will also be developed based on literature reporting layer hen performance under alternative LED lighting regimes and in consultation with research and technical experts in this domain. The student will then collaborate with EFC staff to develop knowledge transfer materials for educating Canadian egg farmers about potential sustainability costs and benefits associated with use of LED lighting systems.
