- 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.

Tidskriftsartikel (refereegranskat)abstract
- This study examines how ecosystem services (ES) have been taken into account historically in strategic spatial plans in Melbourne and Stockholm through a comparative case study analysis of eight strategic spatial plans from 1929-2010. We investigated the types of ES taken into account, and how human-nature relations and the valuation and trade-off discussions regarding ES were framed. An ES coding protocol was developed that categorized and identified 39 ES drawing from the Millennium Ecosystem Assessment and other relevant literature. Only two of the 39 ES were addressed in every plan for both cities, namely freshwater and recreation. While the number of ES referred to in plans has generally increased over time, just under a third of ES in Melbourne and Stockholm were not addressed at all. References to individual ES showed little continuity over time. This variability reveals a time-scale mismatch that has been overlooked in the ES literature with potential urban policy implications. Despite considerable variation in ES addressed across the plans, there is a striking similar pattern in the total numbers of ES addressed over time in both cities. Plans for both cities showed a spike in the late 60s/early 70s, followed by a significant decline in the late 70s/early 80s with the highest number of ES addressed in the most recent plans. Furthermore, our analysis shows that strategic spatial plans generally demonstrate awareness that urban populations are dependent on ecosystems and this framing is an important part of the policy discourse. While specific monetary values were not placed on any ES in the plans, resolution of land-use conflicts requiring tradeoffs between ES and equity of distribution of ES is a central feature of most of the examined plans. We argue that longitudinal policy document analysis represents a useful complement to any attempt to improve understanding of the implications of and opportunities for operationalizing an ES approach in urban practice.
