The transition to a more sustainable economy demands much more of us than simply the development of new technologies. We must look at how these technologies are produced, used, and disposed of; how their use affects our collective behaviour; what policies are needed to promote or limit their potential risks; and the economics of not only the technology and it’s use but of its impacts on society and the environment. HÂþ»­ researchers are actively engaged in studying how weÌýbuild our cities and transform industries, how we develop and implementÌýpolicies,Ìýsustainable development,Ìýhow we value the natural environment, as well asÌýlogistics and supply chains.Ìý

INFRASTRUCTURE AND THE BUILT ENVIRONMENT

Incorporating sustainable practices in the built environment depends upon a confluence of technology, policy, economics, and acceptance by design professionals and society.

Cristina VerissimoÌýmaintains an active professional, interdisciplinary, and collaborative architectural practice, CVDB Arquitectos, that contributes to her academic research. She is also interested in sustainable architecture and is developing a thesis on the architectural use of cork.

Brian LilleyÌýstudies ecological, programmatic, and artistic strategies influencing design. His built projects advocate health and well-being of communities through capacity-building, especially through robust facade and garden design. He is involved in cross-disciplinary research into ceramic materials, as well as augmented environments such as computational representation of interior climate and networked knowledge-enhanced forms of circulation.

Richard leBrasseur’s (GIPL)Ìýengages in research focused on theÌýanalysis and strategic planning of landscapes toÌýimprove human and ecological wellbeing. He examines the impact of urbanisationÌýand uses the findings in order to integrate knowledge, influence policy, andÌýsustain ecosystem services particularly in per-rural environments to create sustainable rural-urban synergies.

ResearchersÌýPedram SadeghianÌý,ÌýJames Forren, Austin Parsons (Architecture, HÂþ»­ University), and (Textiles NSCAD University) have initiated a preliminary collaboration around the use of flax shives in building construction. Flax shives are a by-product of flax fiber production, and the goal of the research is to produce regional carbon sequestering building materials and revitalize the regional industry. Flaxcrete is a composite made from flax shives, lime, and cement. While natural alternatives such as hemp-based concrete have shown promise, they are non-native and water intensive. Flaxcrete is a local, post-industrial, natural building material with unique mechanical and thermal properties. Dr. Sadeghian has characterized the mechanical properties of flaxcrete. Professors Forren and Parsons have conducted a literature review of thermal properties; a comparative simulation of embodied energy values with hempcrete; and plan to conduct future hygrothermal modeling and testing. Professor Green has conducted qualitative analysis of flax shives, flax growth, harvesting and provided a business model summary for industry partner Tap Root Farms (Port Williams, NS) for the use of flax shives in building and construction.

POLICY AND RESOURCE MANAGEMENT

For any new technology can be considered clean, its sustainability advantages and the potential for environmental and social impact trade-offs relative to existing technology options need to be understood. This requires both technical understanding along with the ability to model potential consequences of deployment at scale before this occurs. Where sustainability benefits exist, successful deployment of new technologies frequently requires supportive policies underpinned by an understanding of the social, cultural and economic context.

Michelle Adams’ work focuses on the policies, strategies and technologies that can improve the sustainability of both industry and the communities they intersect. The emphasis is to support regional sustainability through the integration of green technologies, renewable energy, and sustainability strategies applicable within the specific cultural, economic and social context.

Stanley Asah’s research interests and practices are in the domain of understanding and influencing human and organizational behaviors. He uses social-psychological principles and complex adaptive system approaches to inform efforts (direct action, policies, etc.) to initiate, direct, and sustain (promote) pro-environmental behaviors. Focal areas include the adoption, diffusion, and proper use of cleaner technologies; social impacts, social acceptability, and social license to operate cleaner technologies; social justices in the adoption, diffusion and use of cleaner technologies; and facilitating socio-technical transitions to cleaner technologies.

The sustainability of rural life in Atlantic Canada is the focus ofÌýKaren Foster's research, with a particular emphasis on how government policy and everyday life intersect. Her interests in this area include import replacement, youth outmigration, occupational succession in rural family businesses, and rural struggles to protect local public services. She draws upon both qualitative and quantitative methods to study economic issues from a sociological perspective.

Kate SherrenÌýresearches multifunctional landscapes; cultural ecosystem services; climate adaptation; environmental education; and the organizational and intellectual challenges of cross-cutting topics like sustainability. She uses and often integrates various social and spatial research methods in her applied resource-focused research, particularly visual approaches like in situ landscape elicitation.

Peter Tyedmers’Ìýresearch interests include assessing the resource use and environmental impacts of both novel and established technologies. Though Peter’s interests in technology assessment are broad, much of his work has focussed on improving the sustainability of food systems including fisheries, aquaculture, agriculture and feed systems. Peter also engages in research to understand the contributions that ecosystem services make to sustain our food systems. He is particularly motivated to critically examine choices that we make in the name of sustainability to help ensure that we are indeed moving in a positive direction.

Chad Walker’s (he/him) interdisciplinary environmental research is centered around issues of justice, equity, and support for low-carbon transitions. This includes studying the interaction between policy, planning, and local outcomes regarding wind energy development in rural communities, as well as urban-based Local Smart Grid projects (i.e. that combine renewable energy, EVs, heat pumps, battery storage, and smart controls). He also has an active research program relating to Indigenous leadership in renewable energy and the potential for Indigenous-settler reconciliation via a clean energy future. Notably, this includes a community-based partnership with Tobique First Nation in New Brunswick. ÌýHis research activities at HÂþ»­ will increasingly reflect the current and future energy landscapes of Nova Scotia, and Atlantic Canada, including moves toward onshore and offshore wind energy, hydrogen production, and the ‘electrification of everything’. Ìý

Tony WalkerÌýcurrently focuses his research efforts on management and remediation of contaminated sites, ecological impacts and mitigation of industrial pollution, ecological risk assessment and environmental effects monitoring, management of aquaculture impacts, management of Arctic and Antarctic natural resources, air pollution impacts on ecosystems. Most of his recent research has been in partnership with industry related to environmental management and monitoring across Canada.

SUSTAINABLE DEVELOPMENT, INDUSTRIAL SUSTAINABILITY AND THE CIRCULAR ECONOMY

Fulfilling the collective wants, needs and desires of humanity locally, nationally and globally has massively transformed the planet, and increasingly in ways that pose risks to the welfare of humanity and other life on the planet. Finding ways to meet the growing needs of a global population heading to 11 billion while limiting the scale and severity of resulting negative impacts lies at the heart of sustainable development. Increasing deployment of clean technologies and other strategies that lower impacts are essential, and necessitates a comprehensive approach to risk-informed decision making, management, and governance, responsibly balancing the various associated risks and benefits. This includes wider adoption of waste minimization strategies and improved process system design.

Michelle Adams’ work focuses on the policies, strategies and technologies that can improve the sustainability of both industry and the communities they intersect. The emphasis is to support regional sustainability through the integration of green technologies, renewable energy, and sustainability strategies applicable within the specific cultural, economic and social context.

Floris Goerlandt focuses his research on developing risk analysis and safety engineering approaches to understand risks emerging from socio-technical systems in marine industries, and to support related risk mitigation decision-making, organizational management, and societal governance. His work is sensitive to varying degrees of complexity, uncertainty, and ambiguity at different geographical and temporal scales, and ranges from accident prevention and consequence mitigation, to emergency preparedness and response. He is primarily interested in risk and safety implications of clean technologies and renewable energy systems for marine industries, particularly related to maritime shipping, ports, and offshore wind.

LANDSCAPES AND ECOSYSTEM SERVICES

Where and how technologies are used, and the sources of resources needed to provide them can have profound impacts on landscapes and their related ecosystem services (the benefits that humans derive from the functioning of ecosystems). Understanding these consequences of technology use involves insight from ecological, and social sciences including economics.

Kate SherrenÌýresearches multifunctional landscapes; cultural ecosystem services; climate adaptation; environmental education; and the organizational and intellectual challenges of cross-cutting topics like sustainability. She uses and often integrates various social and spatial research methods in her applied resource-focused research, particularly visual approaches like in situ landscape elicitation.

Performance-based landscapes link humans to nature; Richard leBrasseur’s research focusses on the many open spaces and green structures at multiple scales to maintain ecosystem function in the face of urban development. ÌýStrategic infrastructure planning and design serves an important role in climateÌýchange adaption and meeting sustainable development goals. Using both geospatial and qualitative analyses, Rick is able to apply interdisciplinary approaches to value-based environments.

LOGISTICS AND SUPPLY CHAINS

How we move goods between points of supply and demand are easily overlooked when things work smoothly but they are critical in an increasingly globalized world that needs to achieve deep and wide-ranging improvements in how we fulfill our needs. Finding ways to green and shorten supply chains requires the integration of technical, economic and behavioral sciences.

Targetting logistics and energy problems,ÌýDr. Ahmed Saif's research focuses on developing new approaches to address complex decision problems tractably and realistically The four dimensions of complexity: size, nonlinearity, uncertainty, and dynamic behavior are considered using a combination of tools that include: decomposition and approximation techniques, stochastic and robust optimization, metaheuristics, simulation, machine learning, and time-series analysis.

Dr. M. Ali ÃœlküÌýCentre for Research in Sustainable Supply Chain Analytics. His work includes the development of practical logistics policies for green supply chains, the theoretical modeling of service and manufacturing systems, and such interdisciplinary topics as behavioural issues in operations management, sustainable consumption, and the mathematical modeling of societal problems.

Alexander EngauÌýconducts research and professional work that focus on the development of optimization-based models to support and analyze decisions with respect to multiple-criteria tradeoffs, risks and uncertainties. Affiliated with the Departments of Management Science and Information Systems,ÌýIndustrial Engineering, and the Centre for Research in Sustainable Supply Chain Analytics, his scholarly interests are broad in nature and combine theories and methods from mathematical modelling, managerial economics, data science (machine learning)Ìýand decision analysis. He is particularly motivated to engage in collaborations with other researchers, practitioners or students that have theÌýpotential to lead to lasting solutions to present societal problems and challenges.
