“…Comparing average soil microelement concentrations with results of other researches in both urban and rural environments, the first consideration is that trace metal concentration in soils may vary substantially according to both geogenic and anthropic elements. As compared with other studies (Luo et al 2011;Szolnoki et al 2013;Izquierdo et al 2015), the soil Cr content hereby (Kabala et al 2009;Luo et al 2011;Szolnoki et al 2013;Jean-Soro et al 2015;Izquierdo et al 2015) in both urban and rural environments.…”

Urban horticulture is increasingly popular for social and economic benefits. However, edible urban crops may be contaminated by airborne pollutants, thus leading to serious health risks. Therefore, a better understanding of contamination risks of urban cultivation is needed in order to define safe practices. In particular, whereas it is commonly accepted that the contamination of urban-grown food comes from airborne pollutants, little is known on a possible contamination by soils. Here, we studied trace metal risk in horticultural crops grown in an experimental urban allotment garden in Bologna, Italy. Seven experiments were conducted between June and November 2015 on tomato, sweet basil, onion, lettuce, kale, bulb fennel and radish. Treatments included two growing systems, soil and soilless, and two fertilization managements, mineral and organic. Trace metal concentrations were measured in soils, substrates and edible plant tissues. We identified preferentially translocated metals by partitioning analysis of tomato, sweet basil and kale. Results showed that crops grown in a soilless system have a lower metal content of −70 % for Cr, −61 % for Cu, −45 % for Cd and −81 % for Ni, compared with those grown in soil. This finding demonstrates that the major contamination risk in an urban area is unexpectedly related to soil pollution.

“…Studies on ecosystem disservices dealing with potential health risks through soil and crop pollution have differing findings. Results on contamination of soil show that risks for human health can arise through soils contaminated with Pb [180,181] or Cr, As, and Cd [182]. However, not all sites investigated by the studies exceed the limits of contamination.…”

“…In the review, papers critically reflect in particular on potential risks by UPA related with public health (challenge 8). Papers deal with contaminations concerning, for instance, soil health [180][181][182] or crops [166,183]. Also potential risks of contamination through irrigation is considered [184,185].…”

The Role of Urban Agriculture as a Nature-Based Solution: A Review for Developing a Systemic Assessment Framework

Urbanization and achieving sustainable agriculture are both major societal challenges. By reducing food miles and connecting people with nature, food cultivation in cities has several major advantages. However, due to further urban development (peri-) urban agriculture (UPA) is under threat. To strengthen UPA, we argue for considering UPA as a nature-based solution (NbS) supporting systemic approaches for societal challenges. However, academic knowledge on UPA's contribution to various societal challenges of urbanization is still fragmented. This study addresses the gap by conducting a systemic literature review, incorporating 166 academic articles focusing on the global north. The results of the review show that UPA contributes to ten key societal challenges of urbanization: climate change, food security, biodiversity and ecosystem services, agricultural intensification, resource efficiency, urban renewal and regeneration, land management, public health, social cohesion, and economic growth. The value of UPA is its multifunctionality in providing social, economic and environmental co-benefits and ecosystem services. When implementing UPA, social, institutional, economic, technical, geographical, and ecological drivers and constraints need to be considered. To upscale UPA successfully, the study develops an integrative assessment framework for evaluating the implementation and impact efficiency of UPA. This framework should be tested based on the example of edible cities.

“…Thus, these values can be used for nutrient intake calculation and consumer risk assessment (Izquierdo et al, 2015;Warming et al, 2015). However, information on element content in berries grown for self-consumption is not widely represented in available scientific literature, and is especially poor is information for the Baltic States.…”

“…Quality of the urban environment is a problem that has been highlighted but often not taken into account (Säumel et al, 2012;Izquierdo et al, 2015). Increasing urbanisation has often constrained the formation of allotment (community or family) gardens or domestic farms at sites that have been polluted by industry in the past or that are under the influence of daily urban pollution, such as construction dust, industrial or traffic exhaust (Alexander et al, 2006;Wunderlich et al, 2011).…”
