Main principles of AES

The main goals of an AES are the maintenance and improvement of the following facets of the food system (Helenius et al. 2020):

  1. The Biological diversity and the ecological community essential for ecosystem function
  2. The biotic soil, water, and atmospheric condition required by the ecological community
  3. Recycling of elements, called plant nutrients that the process of primary production of crop plants take up, but need again for the next harvest
  4. Energy-self-sufficiency of the system through its primary production by photosynthesis of solar energy
  5. Psychological, socio-cultural (mental, spiritual) connection to the food ecosystem of the people who eat by fostering a sense of food and food citizenship
