Current Recruitment Calls
I am currently recruiting MSc and PhD students for the following funded projects, to commence in September 2019 (application deadline January 31, 2019)
Life Cycle Assessment of LED Lighting for Pullet and Layer Barns (MSc, $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 (with support from UG5) to develop knowledge transfer materials for educating Canadian egg farmers about potential sustainability costs and benefits associated with use of LED lighting systems.
Implications of Supply Management for Food Security, Food Sovereignty and Environmental Sustainability in the Canadian Egg Industry (MSc, $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.
Quantifying the Potential Economic and Resource/Environmental Benefits of Heat Stress Tolerant Beef Cattle using Life Cycle Assessment (MSc Project, $20,000 annually for two years) Heat stress may impact animal performance in several ways, all of which have important economic and environmental repercussions. In addition to direct reductions in feed conversion efficiency, any change in reproductive fitness, morbidity or mortality will similarly compound feed inefficiencies, propagating higher impacts upstream along feed input supply chains as well as at farm-level.
Heat stress is already a significant source of economic impact in the beef industry, where animals are managed outdoors, due to productivity and mortality losses. Projected increases in heat stress-inducing climatic conditions suggest that losses in unmitigated herds may increase exponentially in the near to medium term, undermining profitability, animal welfare, farm viability, and resource/environmental outcomes.
This MSc project will develop regionalized ISO-compliant life cycle costing and environmental assessment models of Canadian beef production systems using OpenLCA software. The models will incorporate data from a parallel MSc project evaluating relationships between heat stress and animal performance in temperate climate cattle that have been cross-bred with warm climate cattle for conferred heat tolerance, and control animal groups. The life cycle models will be used to estimate the potential economic and resource/environmental costs and benefits respectively associated with production of each animal type in face of anticipated increases in heat stress in the Canadian beef herd in 2020, 2050, and 2100 based on regionalized climate change projection models.
External Funding Regardless of availability of dedicated project funding in the Food Systems PRISM Lab, all prospective students are strongly encouraged to explore and apply for relevant external funding as well as teaching assistantships. Students who are awarded a funded project position in the Food Systems PRISM Lab and who also successfully procure additional funding for the project through scholarships, teaching assistantships, and other awards will be "topped up" (i.e. external + project funding) to a maximum of $30,000 annually (over two years) for MSc projects, $35,000 annually (over four years) for PhD projects, and $60,000 annually (over two years) for post-doctoral projects.
