The nutritional aspect of food and nutrition security is achieved when secure access to food is coupled with a sanitary environment, adequate health services, and knowledgeable care to ensure a healthy and active life (free from malnutrition) for all household members 

the complex aspects and interplay of food and nutrition security on different levels. Different factors and sectors on the global/national level play a crucial role and influence the level of food availability and access to food, care, and health services, environmental and hygienic conditions on the sub-national level, which directly affects communities and households. Education plays a crucial role to improve and change the situation on the sub-national level. Improved food availability and access to food, along with aspects of care, determine the individual’s food intake whereas care and questions of health and hygiene influence the individual’s health status . Food intake and health status are closely related to each other and both determine the level and overall goal of food and nutrition security.

Dimensions of Food and Nutrition Security

Four elements build the framework of food and nutrition security: availability, access, use and utilization, and stability. The graph below illustrates the three dimensions describing the food flow from availability and access to use and utilization as well as the aspect of sustainability. These aspects are listed in the bottom rectangle in the graph below, representing the temporal determinant, as well as aspects of an enabling environment or frame conditions of Food and Nutrition Security. Stability fundamentally affects all other elements from the basis.

Access

Access is ensured when all households have enough resources to obtain food in sufficient quantity, quality and diversity for a nutritious diet. This depends mainly on the amount of household resources and on prices. In addition, accessibility is also a question of the physical, social and policy environment. Drastic changes in these dimensions may seriously disrupt production strategies and threaten food access of affected households. As an example, developing countries may be affected by severe droughts or floods more and more frequently. Accordantly, the harvest volume shrinks and the prices for food increase, affecting on the availability and accessibility of food for households. To prevent such negative developments, different technical adaptation measures exist. The construction of infrastructure such as small dams and reservoirs or water spreading weirs to hold back water and raise the shallow groundwater tables is one of them, dykes and improved drainage systems for floods are other ones. In addition, the preservation and rehabilitation of ecosystems, flood sensitive planning or early warning systems and emergency plans further enhance the capabilities to deal with extreme weather events and to preserve the physical environment [7].

Use and Utilization

Use describes the socio-economic aspects of household food and nutrition security, determined by knowledge and habits. Assuming that nutritious food is available and accessible, the household has to decide what food to purchase and how to prepare it as well as how to consume and allocate it within the household.
Another aspect is the biological utilization. This relates to the ability of the human body to take food and convert it. This gained energy is very important when it comes to daily physical activities, for example working in agriculture. Beside that utilization requires a healthy physical environment and adequate sanitary facilities as well as the understanding and awareness of proper health care, food preparation, and storage processes. In this context safe drinking water plays an important role, especially for preparing food and creating a healthy environment for the population. Safe drinking water is connected to groundwater which is often contaminated through human, industrial or agricultural waste water in combination with other factors 884 million people worldwide have no access to adequate drinking water [8][9][10].

Stability

Stability describes the temporal dimension of food and nutrition security, respectively the time frame over which food and nutrition security is being considered. Stability is given when the supply on household level remains constant during the year and in the long-term. That includes food, income and economic resources. Furthermore it is important to minimize external risks such as natural disaster and climate change, price volatility, conflicts or epidemics through activities and implementations improving the resilience of households. Such measure include insurances e.g. against drought and crop failure as well as the protection of the environment and the sustainable use of natural resources like land, soil and water
