First, limited consideration social ecological vulnerabilities risk-related inequalities inhabitants, shortage among them, face different scenarios change, including climate change or events such as Covid-19. Second, disregard intensified negative environmental (and related social) externalities caused distant agricultural production, well lacking nutrient re-cycling potentials from wastewater) replace emission intensive mineral fertilizer use. Third, lack accounting multifunctionality multiple benefits it provides beyond provision food, insurance values, instance maintenance cultural heritage agro-biodiversity. Along lines, we existing knowledge about risks vulnerabilities, spatially explicit metabolism energy, water, nutrients), ecosystem services stronger jointly considered decision-making.
