Investing in sustainability pays off in many ways

AMES, Iowa – A farmer using big data technology to manage pesticide application or a school cafeteria director conducting an audit to reduce food waste are both saving money by investing in sustainability.

These examples do not come from a textbook, but from the work Priyanka Jayashankar, an adjunct assistant professor of management in Iowa State University’s Ivy College of Business; and Erin Bergquist, associate professor of teaching in the Dietetic Internship Program, do in their respective fields. Both want to dispel the misconception that sustainable initiatives do little to boost the bottom line.Priyanka Jayashankar

“Sustainability not only provides an environmental benefit, but there also is an economic and social dimension,” Jayashankar said. “Recognizing this will help us use resources today in such a way that we do not compromise the needs of future generations.”

Jayashankar, who has a joint appointment with ISU’s Seed Science Center, works with businesses and nonprofit organizations to develop sustainable practices without sacrificing profits. She shares this experience in her sustainable supply chain class, which gives students a chance to work with a company on similar issues. She says many students are looking for innovative ways to launch a product or run a business and want to see the advantages sustainable practices can provide.

During the six-month program, ISU interns focus on supporting sustainable food systems and ensuring access to safe, nutritious food.

“They apply these principles in very different settings – hospitals, grocery stores, schools, long-term care facilities or public health programs,” Bergquist said. “For example, several interns are working in schools to identify where food is wasted and implement ways to decrease that waste.”

Building trust, buy-in

In a 2018 study, Jayashankar and her colleagues surveyed nearly 500 Iowa farmers to understand how trust, value and risk influenced decisions to use ag-based technology and big data – tools that promote sustainability. The technology ranged from GPS field mapping to machine optimization tools. According to their findings, the combination of perceived economic and environmental value motivated farmers to adopt the technology. The work is published in the Journal of Business & Industrial Marketing.

“Initially, farmers used big data because they thought it would maximize yields, which was a primary driver. However, once they adopted the practice and saw the other tangible benefits, farmers felt more empowered and more knowledgeable,” Jayashankar said.  

Developing the tools dietitians need to promote sustainability also helps build trust and buy-in. To that end, Bergquist and Kurt Rosentrater, an associate professor of agriculture and biosystems engineering, are leading a two-week class in Paris this June to explore sustainable food systems abroad. As part of the course, Bergquist and the dietetic interns will create a “report card” to evaluate sectors of the food system based on nutrition, economic, cultural and environmental health.

“Sustainability is the future of our profession. If we get stuck in thinking our job is just about one aspect, we lose sight of the big picture,” Bergquist said. “If we can look holistically at community, environmental and individual health, we’ll have a healthier population.”

Sustainability on campus

Bergquist and Jayashankar are not alone in their efforts. Iowa State offers a minor and graduate programs for students interested in various aspects of sustainability. On campus, the Office of Sustainability is responsible for developing and integrating initiatives aimed at reducing waste and minimizing harmful environmental impacts.
