Food trucks as mobile urban food infrastructure: rethinking urban governance for sustainable urban food systems

Rapid urbanization is reshaping food access, livelihoods, public space, and local economic activity within cities. As urban populations grow, sustainable urban food systems must address not only environmental responsibility but also accessibility, adaptability, inclusion, and resilience to changing patterns of urban life [1,2]. These concerns are particularly relevant in rapidly urbanizing regions, including many cities in the Global South, where municipal authorities simultaneously confront employment generation, informal and smallscale enterprise, infrastructure constraints, food accessibility, and competing demands on limited urban space [1,3]. Within this context, although food trucks have been examined across different geographical settings, their conceptual integration within urban food infrastructure and sustainabilityoriented governance remains insufficiently developed in the broader literature, rather than being a gap confined exclusively to cities in the Global South [26].Their mobility, comparatively flexible spatial requirements, lower entry barriers, and capacity to operate near shifting concentrations of consumers distinguish them from conventional fixed-location restaurants [4]. Food trucks may support entrepreneurship, employment, food accessibility, street vitality, and flexible use of urban space; however, these outcomes vary according to location, business model, governance conditions, and access to supporting infrastructure [4,5]. Their environmental contribution is likewise not inherently positive. Waste generation, energy use, packaging, water and sanitation requirements, traffic interactions, and the use of public space can generate additional sustainability pressures when mobile food enterprises operate without appropriate infrastructure and governance [6,7].Food trucks are nevertheless commonly examined as entrepreneurial ventures, hospitality businesses, consumer-service settings, or regulatory subjects [4,7,8]. We argue that these perspectives provide an incomplete account of their relationship with the city. This article therefore proposes the concept of mobile urban food infrastructure to shift attention from the food truck as an isolated commercial enterprise toward the public, spatial, infrastructural, and institutional systems through which mobile food provision interacts with urban environments. Under this perspective, the sustainability contribution of food trucks depends on their integration with urban governance, shared infrastructure, spatial planning, environmental management, and public-space allocation. This Opinion article develops this conceptual argument and examines its implications for urban governance, sustainability trade-offs, and future research. Rather than assuming that food trucks are inherently sustainable, it asks under what conditions mobile food provision can contribute responsibly and equitably to sustainable urban food systems. This perspective is consistent with broader ambitions associated with SDG 11: Sustainable Cities and Communities [1,9]. Figure 1 summarizes the proposed conceptual reframing and provides the foundation for the discussion that follows.Existing food-truck research has largely examined entrepreneurship, consumer behavior, hospitality, and small-business performance [4,8,10]. These perspectives are valuable for understanding venture creation, customer preferences, competitive strategies, and business outcomes, but they provide only a partial account of how mobile food enterprises interact with cities.Food trucks also depend on public space, mobility networks, municipal regulation, utility access, waste-management systems, neighborhood conditions, and consumer accessibility [5,7,11]. These relationships suggest that food trucks cannot be understood solely at the firm or consumer level; their operation is embedded within broader urban systems.The conceptual gap is therefore not simply whether food trucks constitute successful businesses, but how mobile commercial food provision interacts with urban infrastructure, public space, environmental management, and governance. This question is particularly relevant in rapidly urbanizing contexts. However, the Global South should not be treated as a homogeneous urban category, because municipal capacity, infrastructure provision, informality, land-use pressures, and food economies vary substantially between and within cities [1,3,12]. A sustainable-cities perspective must therefore examine the conditions under which food trucks become integrated into urban systems rather than assuming that mobility itself generates sustainability benefits.We use "mobile urban food infrastructure" in a specific rather than metaphorical sense. Food trucks become infrastructure-like not merely because they sell food, but when their operation performs a recurring public-facing service, is spatially coordinated within the city, depends on shared municipal systems, remains accessible to identifiable urban populations, and is incorporated into governance arrangements that manage collective costs and benefits [12,13].Five characteristics therefore define their potential infrastructure role: service function, spatial integration, accessibility, interdependence with shared utilities and public space, and institutional coordination. A food truck operating solely as an isolated commercial vehicle does not automatically constitute urban infrastructure; its infrastructure role emerges through its relationship with these wider urban systems.Food trucks must also be distinguished from street vendors, food carts, and other informal food enterprises. Although these forms may share mobility, flexible location, and dependence on public space, food trucks are vehicle-based food-service units with comparatively greater onboard capacity for food preparation, storage, utilities, and relocation. Street vending encompasses a broader spectrum of fixed, semi-fixed, and mobile activities and may operate under different livelihood, infrastructural, and regulatory conditions [5,6,14]. The present argument therefore concerns food trucks specifically, while drawing cautiously on streetvending scholarship where challenges concerning public space, infrastructure, and governance overlap.Within this framing, food trucks can operate as distributed service nodes that respond to changing concentrations of demand and temporary urban activity while requiring less permanent built space than fixed restaurants [4,11]. Their mobility may allow them to complement, rather than replace, permanent food infrastructure. However, this role remains dependent on access to suitable operating locations, water, electricity, sanitation, waste collection, safe food-handling systems, and transparent rules governing public-space use [6,7,11].Their infrastructure role therefore does not imply sustainability by itself; environmental and social outcomes remain contingent on how mobility, utilities, waste, space, and regulation are managed. This framing raises four questions for sustainable urban governance: Where should food trucks operate? What shared services should support them? How should environmental and spatial externalities be managed? Who gains access to the services and economic opportunities they create? These questions provide the basis for moving from ad hoc regulation toward a more coordinated governance approach.If food trucks are to function as mobile urban food infrastructure, governance must move beyond a licensing-and-enforcement model toward coordinated management of place, shared services, participation, and environmental outcomes. Conventional food-truck regulation commonly focuses on permits, inspections, parking restrictions, and compliance [7,14,15]. These functions remain necessary for food safety and public-space management, but they do not by themselves coordinate mobile food services with urban planning, infrastructure capacity, environmental objectives, or competing claims over public space. We describe the proposed alternative as managed enablement: an approach that retains regulatory oversight while actively coordinating food-truck operations with wider urban systems.Managed enablement can operate through four complementary mechanisms. First, placesensitive regulation can differentiate operating conditions across commercial districts, transport nodes, educational areas, residential neighborhoods, recreational areas, and event spaces rather than imposing uniform spatial rules [17]. Second, shared service infrastructure can provide coordinated access to water, electricity, sanitation, waste segregation, and collection at locations where mobile food enterprises operate [6,7,18]. Third, participatory governance can involve food-truck operators, street vendors, nearby restaurants and businesses, residents, and relevant municipal agencies in decisions concerning location, operating conditions, and the allocation of public space [16]. Fourth, outcome-based environmental standards can establish measurable expectations concerning waste, sanitation, packaging, energy use, noise, wastewater, and restoration of operating sites rather than relying solely on prescriptive restrictions. Such governance also requires interdepartmental coordination. Licensing authorities, publichealth departments, urban planners, transport agencies, waste-management services, and local economic-development bodies may otherwise regulate different dimensions of the same activity independently. Coordination can reduce contradictory requirements while making responsibility for environmental, spatial, and public-health outcomes clearer [19]. Digital permitting and transparent location-allocation systems may support this coordination, but technology should function as an administrative tool rather than being treated as governance innovation in itself.Managed enablement does not imply preferential treatment or unrestricted access to public space. Its purpose is to balance entrepreneurial opportunity with public safety, environmental responsibility, fair spatial access, and the interests of existing vendors, businesses, residents, and other users of urban space. Governance innovation therefore lies not in removing regulation, but in making regulation more place-sensitive, coordinated, participatory, serviceoriented, and outcome-focused.Food trucks may contribute to flexible food access, local entrepreneurship, employment, and temporary service provision, particularly where demand varies across time and place [4,5,11].However, these benefits are neither inherent nor equally distributed. Access to commercially valuable locations may favor operators with greater financial resources, regulatory knowledge, or institutional access, while restrictive zoning and permitting may exclude smaller or less formalized operators [15,17,20]. Food trucks may also compete with existing street vendors, restaurants, and neighborhood businesses for customers and access to limited public space [15,20].Lower entry costs relative to fixed restaurants can broaden opportunities for entrepreneurship [4], but they should not be equated with secure or equitable employment. Mobile food enterprises may involve long working hours, family labor, temporary employment, and revenues that fluctuate according to location, season, weather, and events [ 21]. Similarly, local sourcing and shorter supply chains may generate local economic benefits [22], but these outcomes depend on procurement practices and business models rather than mobility itself.Environmental performance is equally conditional. Recyclable or biodegradable packaging, food-waste reduction, efficient equipment, and responsible water use may reduce environmental impacts [16,23,24]. Conversely, single-use packaging, inefficient generators, waste accumulation, wastewater disposal, congestion, and repeated vehicle movement may create environmental burdens. Nutritional outcomes also require caution: increased availability of mobile food does not necessarily ensure access to affordable or nutritionally balanced food. Sustainability claims should therefore be evaluated against actual operational and environmental outcomes rather than inferred from the mobile format alone.Public-space use introduces an additional question of urban justice. Allocating highly visible or high-footfall locations to food trucks may disadvantage existing vendors, intensify competition, obstruct pedestrian movement, or concentrate commercial opportunities in already well-served districts [15,17,20]. Conversely, overly restrictive regulation can exclude mobile vendors from economically viable locations [15,17,20]. Sustainable governance must therefore consider not only efficiency and service provision, but also who gains access to profitable urban locations, who bears environmental and spatial costs, and whose claims to public space are recognized in regulatory decisions.Future research should test rather than assume the infrastructure role and sustainability contribution of food trucks. At the city level, studies should examine place-sensitive regulation, interdepartmental coordination, public-space allocation, shared infrastructure, and the distribution of regulatory benefits and burdens. At the enterprise level, research should investigate environmental practices, working conditions, sourcing, compliance costs, and sustainability-oriented capabilities. At the urban food-system level, evidence is needed on accessibility, affordability, nutritional quality, competition, environmental performance, and effects on existing food providers.Research should also account for contextual variation. Cities in the Global South differ substantially in municipal capacity, informality, infrastructure coverage, land markets, transport systems, regulatory institutions, and food economies [3,12,17,20]. Comparative, longitudinal, and spatial studies could therefore examine which governance arrangements are transferable, whether shared infrastructure improves environmental and business outcomes, and whether mobile food provision expands access in underserved areas or concentrates in already profitable locations.Ultimately, research should establish when food trucks perform an infrastructure-like urban function, when they remain primarily commercial services, and when their social, spatial, or environmental costs outweigh their benefits. Such evidence is necessary before claims regarding their contribution to sustainable urban development can be generalized.This Opinion article proposes that food trucks can be understood as mobile urban food infrastructure when their operation extends beyond an isolated commercial transaction and becomes integrated with public-space planning, shared utilities, service accessibility, and municipal governance. This framing does not imply that all food trucks constitute infrastructure or that mobility is inherently sustainable. Rather, it provides criteria for examining when mobile food provision performs a wider urban service and how its benefits and costs are distributed.The governance implication is a shift from fragmented licensing and enforcement toward managed enablement, characterized by place-sensitive regulation, shared service infrastructure, participatory decision-making, interdepartmental coordination, and outcomebased environmental standards. Such an approach must simultaneously address trade-offs involving employment conditions, competition with existing food providers, nutritional quality, congestion, waste, unequal access to commercially valuable locations, regulatory exclusion, and competing claims over public space.The central proposition is therefore conditional rather than promotional. Food trucks may complement existing urban food systems by providing flexible and adaptive food services, but their contribution depends on local governance capacity, infrastructure, business practices, spatial conditions, and the distributional consequences of public-space decisions.For cities pursuing SDG 11, the relevant question is not whether food trucks should simply be promoted or restricted, but under what conditions they can be integrated fairly, responsibly, and sustainably into urban food systems [9].
