Graduate student Davidson Obilor Nwaonu studies how research affects consumer choices and shapes climate policy

Davidson Obilor Nwaonu is motivated by climate change. With a wary eye on rising sea levels and food shortages, the agricultural and resource economics graduate student in the College of Agriculture and Natural Resources studies how consumers and policymakers shape climate-smart solutions in agriculture.听

鈥25 percent of global greenhouse gas emissions come from agriculture,鈥 said Nwaonu referencing a published in the journal Science. 鈥淚f we can reduce greenhouse gas emissions in agriculture, we can considerably mitigate climate change.鈥

One way to reduce emissions from agriculture is to adopt climate-smart production practices like integrated nutrient management and precision farming, which use technology like automation and GPS to make farms more efficient. These practices can be expensive, and producers often transfer the cost to the consumers. Consumers are faced with a decision. Will they choose the more environmentally friendly option and give up the opportunity to pay a lower price? As consumers compromise between equally enticing but conflicting options, they are making a trade-off.

鈥淢y research seeks to understand how consumers make the trade-offs between climate-smart attributes of food versus health attributes of food,鈥 Nwaonu explained. 鈥淗ow much are people willing to pay for food that has less impact on the planet versus food that simply satisfies their need for health and nutrition.鈥

Working with his advisor, Leah Palm-Forster, associate professor of applied economics and director of 91原创鈥檚 Center for Experimental and Applied Economics (CEAE), Nwaonu creates hypothetical choice scenarios where consumers choose between products (or decide not to buy). For example, the choices might include milk produced with varying levels of greenhouse gas reduction and milk with the added benefit of probiotics, all at varying price points.听

鈥淧eople look at these options and say, probiotics, no probiotics, 50 percent reduction, 10 percent reduction, which one do I choose?鈥 Nwaonu elaborated. 鈥淭hey're making a trade-off: will they trade off the price and choose the milk with higher attributes, or will they go for the lower price over a climate or a health attribute?鈥澛

Nwaonu found scaling up the benefit of a trade-off, showing the impact of repeated purchases, crucial to consumers鈥 acceptance of climate-smart attributes.听

鈥淧eople want their choices to have significant contributions,鈥 Nwaonu said. 鈥淭hey may feel like buying one gallon of milk cannot save the planet, but if we show them the impact of repeated purchases, they often reconsider.鈥

鈥淚n our choice study, we scale up the costs and benefits of choosing each milk alternative,鈥 Nwaonu elaborated. 鈥淲e show people that if they bought their preferred milk every week for one year, they would have reduced X amount of carbon emissions.鈥澛

鈥淲e highlight the benefit,鈥 Nwaonu continued. 鈥淏y showing how these emissions compare to carbon emissions from a gasoline-powered passenger vehicle driven over several miles.鈥澛

Nwaonu is a busy Blue Hen. In addition to his graduate studies, he works at CEAE as a research assistant and peer advisory council mentor. He never misses a home football game and is a massive fan of the .听

鈥淒avidson is a dedicated member of our CEAE community,鈥 Palm-Forster said. 鈥淗e goes above and beyond to help his peers with their research and to mentor other students.鈥澛

Nwaonu spent the last year as a scholar at the , known as USDA GradCAMP. The program is for master鈥檚 and doctoral students studying climate adaptation or mitigation on working lands or waters in the Northeast with a special interest in climate equity and justice.

The fight for climate justice is close to Nwaonu鈥檚 heart. He came to 91原创 from an area of Nigeria polluted by oil drilling. Farming and fishing, once the livelihood of many residents, have been all but destroyed by pollution.

Nwaonu earned his bachelor鈥檚 degree at the University of Benin, a public research university in Edo State, Nigeria, where he studied agricultural economics and extension services. Afterward, he fulfilled Nigeria's year-long national youth service requirement. Assigned to the National Root Crops Research Institute (NRCRI), Nwaonu managed the Institute鈥檚 demonstration plot and supported field research in root and tuber crops research.

鈥淢any of our staple foods in Nigeria are from root and tuber crops,鈥 Nwaonu said. 鈥淭he institute researches how to improve productivity, yield and disease resistance in crops like yams, cassavas, and potatoes.鈥

At USDA GradCAMP, Nwaonu listened to climate equity practitioners and academics discuss how climate change disproportionately affects underserved communities, working lands like farms, and the people who work them. He learned how research can affect policy change and support climate justice.听聽

鈥淭he overall aim of the USDA GradCAMP program is to see that there is research, there is policy, and there are efforts to ensure sustainability in these areas,鈥 Nwaonu said. 鈥淭o ensure equity and justice in working lands and waters across the Northeast region.鈥

In addition to presenting his research, Nwaonu collaborated with his fellow scholars. They created factsheets concerning the working lands and waters of the Northeast, which are available on the USDA website.

One presentation stood out to Nwaonu. Nathan Kleinman, the Philadelphia-based Experimental Farm Network (EFN) co-founder, spoke about collaborative plant breeding and sustainable agriculture research. After the workshop, the USDA GradCAMP scholars toured Rabbit Hole Farm and Garden of Hope Farm, two urban agriculture sites in Newark, New Jersey.

鈥淭his was the height of my experience at GradCAMP,鈥 Nwaonu said with a smile.听

He was amazed by the abundance of vegetables, spices, and flowers flourishing in these urban farms. A sense of community also blossomed in these reclaimed spaces with meditation classes, storytelling, and youth programs.

鈥淔ood produced within the radius of where it is needed solves many problems,鈥 Nwaonu underscored. 鈥淔irst of all, people can eat fresher food. And if the food does not travel far, it reduces the carbon footprint.鈥

Nwaonu would like to see urban agriculture on a larger scale in cities worldwide.

鈥淭hen we鈥檇 have a greater chance of eating locally produced foods that meet the nutritional needs of people and at the same time reduce the carbon footprint. Seeing these urban farms made me realize that everything is possible!鈥 Nwaonu said.
