- Global urbanization and food production are in direct competition for land. This paper carries outa critical review of how displacing crop production from urban and peri-urban land to other areas– because of issues related to soil quality – will demand a substantially larger proportion of theEarth’s terrestrial land surface than the surface area lost to urban encroachment. Such relationshipsmay trigger further distancing effects and unfair social-ecological teleconnections. It risks also settingin motion amplifying effects within the Earth System. In combination, such multiple stressors set thescene for food riots in cities of the Global South. Our review identifies viable leverage points on whichto act in order to navigate urban expansion away from fertile croplands. We first elaborate on thepolitical complexities in declaring urban and peri-urban lands with fertile soils as one global commons.We find that the combination of an advisory global policy aligned with regional policies enablingrobust common properties rights for bottom-up actors and movements in urban and peri-urbanagriculture (UPA) as multi-level leverage places to intervene. To substantiate the ability of aligningglobal advisory policy with regional planning, we review both past and contemporary examples whereempowering local social-ecological UPA practices and circular economies have had a stimulatingeffect on urban resilience and helped preserve, restore, and maintain urban lands with healthy soils.

- Food security has always been a key resilience facet for people living in cities. This paper discusses lessons for food security fromhistoric and prehistoric cities. The Chicago school of urban sociology established amodernist understanding of urbanism as an essentialist reality separate from its larger life-support system. However, different urban histories have given rise to a remarkable spatial diversity and temporal variation viewed at the global and long-term scales that are often overlooked in urban scholarship.Drawing on two case studies fromwidely different historical and cultural contexts – the Classic Maya civilization of the late first millennium AD and Byzantine Constantinople – this paper demonstrates urban farming as a pertinent feature of urban support systems over the long-term and global scales. We show how urban gardens, agriculture, and water management as well as the linked social–ecological memories of how to uphold such practices over time have contributed to long-term food security during eras of energy scarcity. We exemplify with the function of such local blue–green infrastructures during chocks to urban supply lines. We conclude that agricultural production is not “the antithesis of the city," but often an integrated urban activity that contribute to the resilience of cities.

Buried solutions: How Maya urban life substantiates soil connectivity

- Soils are a pivot of sustainable development. Yet, urban planning decisions persist in compromising the usability of the urban soils resource. Urban land cover expansion to accommodate an increasing population results in soil sealing. Concealment of and physical obstructions to soils prevent urban populations from engaging with their soil dependency. The concept of soil connectivity recognises that nurturing mutually beneficial soil–society relations is an essential dimension for achieving soil security. The concentrated populations of urban environments acutely require productive soil–society relations and offer the greatest potential for enhancing soil connectivity. Soil connectivity remains notably under-researched, however, resulting in deficient evidence to substantiate exactly how soil connectivity can contribute to sustaining urban life. The entanglement of soil and urban development has been critical throughout history, but seldom recognised in soil security discourse. We review the manifestation of effective soil connectivity in Precolumbian lowland Maya tropical urbanism. Archaeological evidence reveals, first, that lowland Maya urban settlement patterns largely preserved the availability, proximity, and accessibility of soils in the subdivision and configuration of urban open space. Second, Maya urban life included practices that proactively contributed to the formation of soils by adding to the stock of soils and improving beneficial soil properties of the thin and often nutrient-poor soils resulting from the regionally dominant karstic lithology. Third, a range of Maya landscape modifications and engineering practices enabled the preservation and protection of soils within urban environments. We derive evidence-based insights on an urban tradition that endured for well over two millennia by incorporating intensive soil–society relationships to substantiate the concept of soil connectivity. Inspiring urban planning to stimulate soil connectivity through enhancing the engagement with soils in urban life would promote soil security.
