Multidimensionality as one key-concept in Nutrition Ecology means that nutrition is depicted in the four dimensions health, environment, economy, and society. This allows including the complete spectrum of aspects in the field of nutrition. In accordance with the concept of sustainable development with integration as an important claim even in the nutrition ecological research approach the dimensions have to be considered simultaneously and coequally. Coequally means that the focus is not primarily on health but on all four dimensions of nutrition, as they all are usually involved in the causality of a problem or its solution. The aim is to develop future concepts of food and nutrition which are compatible with health, environment, economy, and society - with a local and a global perspective.
As one supportive tool serves the nutrition-ecological modelling technique NutriMod which supports integrative problem-solving processes by facillitating problem analysis, supporting to work on complex problems and assisting the impact assessment. In inter- or transdisciplinary processes it can help to get a common understanding of the phenomenon and can support discipline-transcending knowledge integration.
