In the first two years of our research cluster, we have laid crucial groundwork for developing the UBC Farm as a Long Term Agroecological Research Station.This strong foundation has enables the UBC Farm to be used as a living laboratory for developing long-term experimental protocols to examine trade-offs and synergies in diversified agroecosystems, and to be placed as the central hub in a Coordinated Distributed Experimental Network (CDEN) of diversified research farms around the world.
Cluster researcher Dr. Mark Johnson received funding to establish a “living laboratory for water sustainability” at UBC Farm through UBC Sustainability Campus as a Living Laboratory initiative.
The project will develop a water innovations node for UBC’s Campus as a Living Laboratory initiative to conduct water monitoring and evaluate water use reduction strategies to minimize the water footprint of agriculture at the UBC Farm and support UBC’s Water Action Plan. The project will increase the capacity of UBC Farm as a leading living laboratory for research, teaching, and learning on water sustainability with academic, public sector, and industrial partners. The project will implement new, smart, integrated water and climate monitoring technology at UBC Farm. This will enable living-lab based research to develop water conserving strategies and conduct innovative research across the food-energy-water nexus.
A Living Lab for Biodiversity Monitoring in Agroecosystems
Biodiversity, across multiple scales and levels, is the foundation of agricultural productivity and contributes essential ecosystem functions and services to food systems.
In 2019, cluster members Matthew Mitchell, Juli Carrillo, and Hannah Wittman secured funding from the UBC Campus as a Living Laboratory Initiative, BRITE, the VPRI Biodiversity Research Excellence Cluster, and the VPRI Diversified Agroecosystems Research Excellence Cluster to implement a long-term monitoring program for biodiversity at the UBC Farm. The UBC Farm provides a unique opportunity to monitor the biodiversity important for agroecosystem food production and other ecosystem services, with future opportunities to connect this to other socio-ecological outcomes relevant to the broader community and food systems. Long Term Biodiversity Monitoring will ensure that the diversity of life at the UBC Farm, including birds, plants, and insects, is recorded each year. This will help us understand how biodiversity at the UBC Farm is changing over time and how this affects important ecosystem services (benefits we can receive from the natural environment) that aid people, help crops grow, and contribute to overall ecosystem sustainability. Read the draft UBC Farm Biodiversity Monitoring Plan here.
The CSFS in collaboration with farmers, and cluster members, are working on a free, open-source web app to both advance science and help farmers manage the financial and environmental aspects of their business. The project is led by cluster leads Dr. Zia Mehrabi, a Research Associate at UBC’s Institute for Resources Environment and Sustainability and Dr. Hannah Wittman, CSFS Academic Director, and Professor at the Institute for Resources Environment and Sustainability.
Mehrabi along with a team of scientists, farmers, designers, developers, CSFS staff, and undergraduate students have created LiteFarm to help improve sustainable farming through the democratization of agricultural technology. LiteFarm is built to both help individual farmers with their day-to-day operations, and to help the wider farming community through identification of solutions for better farm management practices and outcomes, particularly in small-scale, diversified farming contexts, for which empirical analyses are currently lacking due to a dearth of data and funding.
Cluster members Hannah Wittman, Loren Rieseberg, and Matthew Mitchell secured funding for and hosted a Peter Wall Institute for Advanced Studies (PWIAS) International Research Roundtable in May 2019 on the intersection between agrobiodiversity and food security/sovereignty. With many cluster members and international researchers participating, workshop participants discussed a vision of agroecosystems and food systems where farmers, citizens, consumers, scientists, and decision-makers collaborate to evaluate, understand, monitor, and manage the links between biodiversity and food security. The outcome of the workshop was to collectively envision a research/action agenda for the next 5-10 years around the intersections of agrobiodiversity and food security, with a manuscript developed from the workshop to be submitted in 2020.

Learn more about the research project: Systematizing links between food security and biodiversity conservation through citizen science
In 2019, cluster members Zia Mehrabi and Claire Kremen secured funding for a SESYNC project to assess the benefits and costs of agricultural diversification with respect to the food-water-energy nexus. The project includes 15 current cluster members as well as new invited participants from Europe and Australia; the interdisciplinary team will perform collaborative research and gather for three workshops over the course of 18 months.
Can Microbes Help Plants Mitigate Climate Change?
Cluster members Cara Haney and Juli Carrillo, along with CSFS as a collaborating partner, have secured two years of funding ($200,000) from the Weston Foundation’s Seeding Food Innovation initiative to test whether beneficial microbes can directly mitigate the detrimental effects of climate change on plant nutrition as well as resistance to insects and drought. This work will lay a foundation to implement microbes in field and greenhouse production to improve food security in Canada and around the globe.
Cluster member Sean Smukler has secured $281,000 from the Farm Adaptation Innovator Program to assess the field performance of a suite of novel management practices on soil-water dynamics. The study will include controlled experiments, on-farm demonstration trials, and modelling of longer-term impacts and associated farm economics. Using results of field trials, through collaboration with participating farmers, Sean and his team will develop a set of site-specific recommendations that account for variation in soils and climate, to share through farmer networks, producer associations, workshops and digital planning tools.
Studying Key Pollinators
Native bumble bees are key pollinators of crops like blueberries, squash, and tomatoes, making them critical players in BC’s Agricultural Sector. Collectively, habitat loss, lack of suitable food plants, interactions with commercial bees, and changing climate are all taking a toll on native bumble bee abundance and diversity. In 2019, cluster members Juli Carrillo, Tara Moreau, and Andy Black received an LFS Internal Research Grant for $33,000 to monitor and track native bumblebee abundance across various locations on campus, including the UBC Botanical Garden and UBC Farm. This research pilot study will also determine the preferred host plants, microclimate, and weather variables associated with bumble bee abundance and diversity. Fueled by citizen science, Project BEE Smart aims to increase public ownership and awareness of native bumble bee conservation, and increase the public’s literacy on native bumble bees of our region.
Adapting to Climate Change in the Cariboo and Okanagan
Cluster members Hannah Wittman and Lisa Powell, along with collaborators Jon Janmaat, John Church, David Connell, and Lenore Newman, and BC ACARN as a collaborating partner, have secured a $210,000 SSHRC Partnership Development Grant to study agricultural adaptation to climate change in two British Columbia regions, the Cariboo and the Okanagan. The research team will identify the challenges to adaptation and work with groups across the academic, governmental, and industrial sectors to identify opportunities for enhancing the adaptive capacity of BC agriculture.
Value of Restored Habitats
Cluster members Claire Kremen and Juli Carrillo have secured two years of funding ($300,000) from the Canada – British Columbia Agri-Innovation Program for a project that aims to assess the value of various types of restored habitats (e.g., grass margins, native-plant hedgerows, grassland set-asides, etc.) in Delta, BC for supporting populations of beneficial insects and how increases in these populations impact crop yields and profitability. By quantifying the impact of restoring semi-natural/natural habitat on farmlands on crop yields and profitability, this project will address many concerns local growers have about grass margins, hedgerows, and grassland set-asides.
Cluster members Evan Fraser, Zia Mehrabi, Hannah Wittman, and Tammara Soma, along with multiple other co-PIs from across Canada, have secured a $399,000 SSHRC Insight Grant to conduct research on the social impacts of digital technology on Canadian growers.
Participatory Variety Trialing and Breeding for Commercial Organic Vegetable Growers and Seed Producers in Canada
Cluster members Alex Lyon, Loren Rieseberg, and Marney Isaac, as well as Canadian and North American collaborators and extension specialists, have secured a five-year, $499,000 grant through Organic Science Cluster III (Organic Federation of Canada and the Organic Agricultural Centre of Canada at Dalhousie University) to perform participatory variety trialing and breeding of cabbage, bell pepper, and squash. The research team will build on a collaborative varietal development research network consisting of organic farmers, university researchers, and industry stakeholders.
These activities will support a comprehensive knowledge generation and transfer program on variety performance and in-depth training in on-farm plant breeding, improving the ability of organic farmers to engage in future variety development. This project will also increase the Canadian capacity for organic vegetable breeding by training undergraduate and graduate students in the basic principles and practices of evaluating and improving plant varieties. Ultimately, the goal of this research is to ensure that Canadian organic vegetable farmers and seed producers have access to high quality vegetable seeds that can perform competitively in Canadian organic farming systems.
Cluster members Juli Carrillo, Cara Haney, and Simone Castellarin have secured a five-year grant ($746,000) through Organic Science Cluster III (Organic Federation of Canada and the Organic Agricultural Centre of Canada at Dalhousie University) for a project that aims to develop multiple strategies for spotted wing drosophila (SWD) pest management, with a focus on ecological and organic methods of control. The international project team, composed of academic, government, and industry partners, will support six graduate students over 5 years and evaluate four independent but potentially synergistic strategies for SWD management.
Cluster members Sean Smukler and Zia Mehrabi, as well as collaborators Shabtai Bittman and Derek Hunt, have secured three years of funding ($150,000) for a project that aims to increase the capacity of organic vegetable farmers to efficiently utilize nutrients and thus increase the economic and environmental performance of their farming system.
Cluster lead Hannah Wittman and IRES faculty member Amanda Giang secured two years of funding through UBC’s newly established Program for Undergraduate Research Experience. Hannah and Amanda, along with multiple cluster members and other faculty from Science and Arts, have developed an immersive research training experience in socio-ecological systems for undergraduate students through a new interdisciplinary research training course, Socio-Ecological Systems Research (ENVR 448).
Cluster members Simone Castellarin and Juli Carrillo have received an NSERC Research Tools and Instruments grant for $137,000 to purchase two growth chambers for LFS and IRES faculty members, including multiple cluster members, to work on projects that aim to elucidate the mechanisms controlling crop response to environmental factors and climate change. Project leads expect that the research conducted with this infrastructure will provide critical knowledge to support BC, Canadian, and international scientists and farmers in developing crop management strategies to optimize production, minimizing inputs and negative outputs (greenhouse gas emissions) under future climate scenarios. Additionally, the chambers will provide unique opportunities for improving student and postdoctoral training using research infrastructure that enables new experiments in a highly controlled environment where future climatic scenarios can be simulated, and the impact on crop physiology and productivity and soil and insect ecology can be explored.
Cluster members Dr. Dorn Cox and Dr. Zia Mehrabi are leading teams developing open-source farm management tools that will enable farmers to make data-informed decisions about their management practices.
Dorn is a founder of FarmOS, an open-source web-based application for farm management, planning, and record-keeping. Zia is the project lead of LiteFarm, an open-source farm management app developed by UBC undergraduate students. Additionally, Zia plays a leading role in the establishment of a Data-Driven Agronomy Working Group at the CGIAR.
As part of the LFS 496 Career Development Internship program, two undergraduate students trialled FarmOS using UBC Farm datasets. Their main goals were to determine how compatible FarmOS is with UBC Farm’s current data management system, and how well FarmOS provides the capabilities that UBC Farm’s system currently lacks. They documented this trial and provided recommendations to the FarmOS development team in a summary report. With undergraduate engagement through internship and work-learn programs, we will trial LiteFarm and other farm management tools in 2019, with a focus on integrated pest management and biodiversity monitoring, integrated nutrient management, and integrated water management.
