Frugal continuity names a condition in which sustained movement becomes possible not through abundance but through the controlled reduction of material and logistical friction. Mobility here is neither a romantic celebration of wandering nor a simple transport variable. It is a research condition produced by the relation between body, route, equipment, ordinary services, attention and time. Mobile-methods scholarship establishes the first part of this argument by refusing to treat movement as a neutral interval between sites. Hein, Evans and Jones place theory, technology and practice inside the methodological problem of mobility itself, while Moles distinguishes mobility as an object of study from mobility as a methodological operation: following people, objects or ideas changes what can be known because knowledge is produced within flows, stoppages, encounters and networks rather than after them. Cheng sharpens this into an embodied epistemology.
Walking fieldwork is not a frictionless collection technique but a spatially unstable practice shaped by insecurities, distractions and reorientations; fieldnotes, photographs and short video fragments are valuable precisely because the urban field arrives as affective material, rhythmic heterogeneity and mundane interruption rather than as a clean sequence of preselected variables. Bartoletti, Sacchetti and Mariani extend this logic into the urban forest, where walking becomes attunement and “controlled getting lost”: non-directive movement accommodates detours, surprises and contradictory sensory cues that would be suppressed by a highly structured itinerary. Their insistence that walking does not automatically reveal an authentic experience is crucial. Mobility produces knowledge only when its contingencies are treated analytically. The same applies to prolonged comparative fieldwork. A light bag, a laptop instead of paper, a few washable garments, purchased water, hotel toiletries, ordinary cafés, supermarkets, laundries, regional trains and inexpensive rooms are not biographical trivia surrounding research; they are the mundane technical arrangements that keep the field open. Guma’s account of everyday infrastructures provides the conceptual hinge. Against the dominance of spectacular, capital-intensive or technologically “advanced” systems, he asks urban theory to read ordinary infrastructures on their own terms through incomplete relationalities, mundane temporalities and heterogeneous modernities. The consequence is decisive: the infrastructures that matter most to prolonged fieldwork are often those that disappear into routine precisely because they work. A washing machine restores mobility; a supermarket prevents the need to carry provisions; a hotel bath, however small, restores the body; a café becomes workstation, observation point and temporal hinge; a slow regional train converts transfer time into continued territorial exposure. Such services do not merely support the observer from outside the method. They calibrate duration, bodily equilibrium and the possibility of serial comparison. Sufficiency scholarship gives this material economy a second register. Hall’s degrowth account of tourism distinguishes qualitative development from aggregate quantitative growth and joins efficiency to sufficiency: less throughput, longer use, slower replacement and a reduction of unnecessary resource demand. Levelt, Chevrollier and Argyrou show why sufficiency should not be collapsed into degrowth or regeneration, even where they share a strong-sustainability commitment. Sufficiency is especially useful here because it asks about adequate scale rather than maximal reduction. Stuhlfauth, Saheb and Bouzouina similarly define mobility sufficiency through the double boundary of planetary limits and wellbeing, finding that structural changes in accessibility and urban form matter more than behavioural or technological fixes alone. Zell-Ziegler and colleagues translate this into mobility policy as practices that avoid demand for energy, materials, land and water while still delivering wellbeing. Yoo and Zhou’s work on minimalist slow travel, although framed through tourism psychology rather than field epistemology, adds another useful tension: slowness and reduced material complexity can support flow and resilience, but only when minimalism remains a condition of mobility rather than becoming an aesthetic of self-purification. Frugal continuity therefore rejects both heroic endurance and lifestyle minimalism. Its unit is not deprivation but operational sufficiency: enough equipment, enough rest, enough connectivity, enough food, enough clothing, enough shelter, enough mobility to keep observation active without converting the support system into the dominant burden of the journey. The field persists because the observer’s material world remains small enough to be repeatedly reassembled. A research corpus built under conditions of frugal continuity acquires a distinctive epistemic architecture. It is not simply a collection of places but a temporally extended field whose comparability depends on keeping transitions permeable. The city does not end at the hotel door, in the supermarket aisle, at the washing machine, or on the platform; each apparently secondary scene regulates the observer’s capacity to continue noticing. This changes how an archive should represent mobile fieldwork. Instead of treating photographs, notes and city observations as isolated outputs while excluding logistical episodes as noise, the archive can register those minor infrastructures that preserve the continuity of observation: the train that stops at every settlement, the single track that forces one direction to wait for the other, the café where impressions are consolidated, the laundromat that makes six light socks sufficient for weeks, the room whose minimal equipment is adequate because the wider urban system supplies what is missing, the small grocery purchase that replaces the need to transport provisions, the familiar city revisited after a sequence of unfamiliar ones, the forest interval that resets perception before re-entry into urban density. This is not a demand to document everything. Frugality must also govern the archive. A sustainable comparative corpus depends on selective retention: enough traces to reconstruct transformations of attention, route and bodily state, but not so much documentary mass that the act of recording overwhelms the capacity to remain present. Cheng’s emphasis on mundane vignettes and reorientation, Bartoletti et al.’s adaptive detours, and Moles’s understanding of mobility as both practice and method all support an archive in which movement generates the categories through which subsequent movement is perceived. Guma’s mundane temporalities deepen this by showing that infrastructural knowledge emerges through duration, maintenance, partial functionality and habitual use rather than only through breakdown or spectacle. Frugal continuity therefore transforms comparison from a sequence of discrete site reports into a cumulative field condition: earlier places remain active, ordinary infrastructures preserve the observer’s capacity to move, and repeated movement alters what counts as novelty. Under prolonged exposure, the comparative apparatus becomes simultaneously more efficient and more vulnerable. Familiarity accelerates recognition but can produce premature closure; bodily adaptation permits longer routes but can conceal fatigue; a reduced material kit lowers logistical friction but may privilege observers whose mobility, health and institutional circumstances permit such reduction. The method therefore requires explicit limits. Sufficiency cannot become a universal prescription for how fieldwork should be conducted, nor can walking distance become a proxy for epistemic seriousness. The strongest contribution of frugal continuity is more precise: it makes visible that every extended field practice rests on a material threshold below which continuity fails and above which logistics begin to dominate the field. This threshold is situated, bodily and revisable. In Socioplastics, that threshold can become an infrastructural principle for the construction of corpora, archives and public knowledge: retain what allows relations to persist, discard what adds weight without increasing legibility, and treat maintenance as a generative operation rather than a secondary task. The resulting archive is not austere for aesthetic reasons; it is light enough to remain traversable, redundant enough to survive, and open enough to absorb successive contexts without losing its internal continuity. A field sustained in this way does not oppose abundance with scarcity but reorganises abundance around persistence: many observations can be generated from few possessions, many comparisons from repeated ordinary routines, and many epistemic transitions from infrastructures that remain nearly invisible until they fail. The archive thus becomes less a warehouse of accumulated evidence than a maintained environment for recurrence, in which travel, rest, washing, eating, waiting, orientation and re-entry are recognised as operations that preserve the capacity to know. Within Socioplastics, this condensation is MaintenanceReturn.
