Global maize trade and food security: implications from a social network model
1Department of Food Science and Human Nutrition, Department of Agricultural, Food, and Resource Economics, Michigan State University, MI, USA.
Summary
Global maize trade is analyzed using a social network model. The US dominance as an exporter poses food security risks if its supply is disrupted, impacting global food availability.
Area of Science:
- Agricultural Economics
- Network Science
- Food Security Studies
Background:
- Maize is a critical global crop for food, feed, and industry, essential for food security.
- Understanding international trade patterns is vital for assessing global food supply vulnerabilities.
Purpose of the Study:
- To develop a social network model of global maize trade.
- To analyze trade patterns and identify potential food security risks.
- To assess the impact of disruptions in maize availability.
Main Methods:
- Utilized U.N. Commodity Trade Statistics Database data from 2000-2009.
- Developed a social network model to map maize trade between 217 nations.
- Analyzed trade volumes, market segregation, and network structures.
Main Results:
- Identified distinct clusters in maize trade, notably Europe, South America (Brazil/Argentina), and the United States.
- The United States emerged as the largest exporter, while Japan and South Korea were major importers.
- A star-shaped network centered on US exports highlighted vulnerabilities due to limited alternative suppliers for importing nations.
Conclusions:
- The US's dominant export position creates potential food security risks for nations reliant on its maize supply.
- Disruptions to US maize exports could jeopardize global food security, especially considering factors like biofuel production.
- Network analysis provides crucial insights into the interconnectedness and vulnerabilities of the global food system.

01:16What is Climate?
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.
02:16Light Acquisition
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.
02:39Gene Flow
Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.
02:26Protein Networks
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

02:06Social Exchange Theory
We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).
01:26Social Exchange Theory
As formulated by John Thibaut and Harold Kelley, Social Exchange Theory explains human relationships as economic-like exchanges that maximize rewards and minimize costs. This theory suggests that individuals engage in relationships to gain benefits and reduce burdens, similar to economic transactions. It has been widely applied to various types of relationships, including romantic, professional, and social interactions.Rewards and Costs in RelationshipsRelationship rewards include emotional...
