How might food security issues of availability, access, and affordability essential for living a healthy life impact society in the future?
Background
Nutritious food is a basic human need. While global food production has expanded, approximately one in three people remain food insecure. Food availability – how much food exists – is the first hurdle to feeding the global population.
Food Security served as Practice Problem 1 for Northern Hemisphere students during the 2024-2025 school year and Southern Hemisphere students in their 2025 school year.

Context
Food security is different in every place and yet impacts every society. Infrastructure, environmental conditions, and political stability can all have significant impacts on the production of food. Environmental events such as droughts and rising sea levels also impact existing food sources. Economic, legal, and social barriers may thwart access to available food. Political conflicts, for example, interrupt supply chains and divert food away from those in need. Even when there is enough food available, and people have access to it, their food security may be threatened by the safety of the food.
