The fields of Food, Water, and Environmental Security are important areas of security as they are directly connected to human survivability. While these are three areas of security that are separate, they were combined into one section here because of their similarities and overlaps with each other.

Food Security involves universal access to adequate nutrition, crop and animal sciences, and agricultural engineering technology. It also includes the transportation, storage, and distribution, and the effects of interruption of food supplies that result from natural disasters and conflicts.

Water Security includes the study of the interaction of technology and social organization in the delivery and quality of water at the household, community, regional, and national levels.

Environmental Security includes persistent environmental effects from human activities, including concepts such as climate change deforestation, and soil degradation. While there is overlap between this area of security and other topical areas, Environmental Security brings a different perspective of security threats and how to mitigate issues.
