Research on agriculture and food Security aims to provide insight that can assist in developing more sustainable agriculture and food systems that can better solve local, regional, national, and/or global food and nutritional insecurity. Food security exists when all people have physical, social, and economic access to sufficient, safe, and nutritious food to fulfill their dietary needs and food preferences for an active and healthy life at all times. Food security is determined by three factors: food availability, accessibility, and consumption. Household resources, discretionary income, and socioeconomic level all play a role in food security. It is also inextricably tied to other issues including food costs, global climate change, water, energy, and agricultural expansion. Physical (temperature, soil quality, and gradient) and human (technology) elements have historically influenced the amount and type of food produced in any given location.
