In Hanjie the rules are simple. In this game of logic and creativity, the players, often working on medium-sized grids of 225 squares, use numbers on the rows and columns as clues to determine which boxes to shade. At first, the prospect of seeing a beautiful picture seems almost unfathomable. However, through patience and collaboration from every corner of the page, these small seemingly random squares gradually come together to reveal a masterpiece—one square at a time.
In a sense the efforts of Duke’s Climate Commitment are no different. The issue of climate change has proven to be a multifaceted one. One in which many parties play a role. However, with initiatives such as Duke’s Forever Learning Institute, the probability of tackling these issues becomes much clearer.
Recently Duke’s Forever Learning Institute, an interdisciplinary educational program for Duke alumni, hosted Professors Norbert Wilson and Maiken Mikkelson for a compelling session on the impact of climate change on food and agriculture. Wilson, an agricultural economist and the Director of the World Food Policy Center at Duke, specializes in addressing critical issues related to food access, nutrition, and food security. Mikkelsen, a distinguished expert in physics, electrical, and computer engineering, explores the potential of nanomaterials to revolutionize agricultural processes, paving the way for innovative solutions in the field. Together, they explained how advancements in nanomaterials can improve food security and sustainability.
Throughout the session, Wilson emphasized the concept of food security. He began by clarifying the difference between “food loss” and “food waste.” Food loss occurs at the agricultural level. It refers to food that is produced but never reaches consumers, often due to challenges such as poor harvesting seasons, labor shortages for harvesting, or other natural factors. He describes the ways in which loss occurs across the board but disproportionately affects less developed countries. Wilson also explained how food waste occurs at the consumer level. He details how it goes beyond the waste of a product but is also a waste of the resources used to create that product.
Wilson illustrated the significance of these issues by drawing out the larger issue of food insecurity. Food insecurity describes an inability to access food or concerns about accessing food. In the United States 13.5 percent of citizens struggle with accessing food. This can lead to a number of negative health outcomes such as cardiovascular issues and diabetes. Food insecurity can also lead to behavioral and performance issues, particularly in young children.
This is where Mikkelson comes in. She described a term known as Precision Agriculture. In this, researchers observe and measure agriculture fields and extra data to see what resources such as water, and fertilizer is needed at each part. In this, they hope to retrieve good information through wavelengths as a means of getting a spectral fingerprint that supplies information about the crops. Mikkelsen describes her interest in leveraging nanomaterials to create lightweight, cost-effective hyperspectral cameras capable of capturing detailed spectral fingerprints of crops. She hopes that these materials can be employed around the world, and low resource settings to increase crop yields. The greatest roadblock in this would be the price and issues with widespread application. However, once applied it would hold the ability to detect key characteristics such as nutrient deficiencies, water stress, or disease presence.
Our world is wildly affected by climate change. Climate change and agricultural production hold a very dependent relationship and fixing one side holds the ability to correct the other. This is what makes the work and research of those such as Wilson and Mikelson all the more important. Their efforts show how we can utilize technology to not only enact social change but also reverse our climate issues. Their research highlights not only the urgency of addressing food security and agricultural sustainability but also the transformative potential of interdisciplinary approaches.
Just as the game of Hanjie reveals its masterpiece one square at a time, tackling climate change requires collective effort and patience. Each initiative, whether through advanced nanotechnology or policy-driven solutions, brings us closer to a sustainable future. Duke’s Forever Learning Institute serves as a platform to connect these ideas, inspiring action and innovation that can shape a better tomorrow—one step at a time.
based and enzymatic, meaning its essentially grown using enzymes from beans. Testing in the New York Harbor yielded some promise: the cement appeared to resist corrosion, while becoming home for some oysters. The Design Climate team is now trying to bring it to more widespread use on land, while targeting up to a 90% reduction in carbon emissions
