تبیین الگوی انقباض در سکونتگاه‌های کوچک ارتقایافته ایران: مطالعه موردی شهر نیر

Urban shrinkage is a multidimensional phenomenon affecting many regions worldwide since the late twentieth century, characterized by population decline, economic stagnation, and weakening urban functions. Existing scholarship has largely focused on large industrial cities in the Global North, where decline followed earlier growth. In the Global South, however, shrinkage often emerges in small and medium-sized settlements that are more vulnerable to out-migration and environmental shocks due to weaker institutional and economic capacities.



In Iran, administrative upgrading of villages into cities has been a major spatial policy. Lowering the population threshold for city designation from 10,000 to 3,500 people significantly increased the number of small upgraded settlements. This process produced what Iranian scholars call kham-shahrs (cities-on-paper): settlements granted legal urban status without sufficient economic, institutional, or functional foundations for genuine urban development. Many face economic stagnation, population decline, and declining regional significance, yet this phenomenon remains understudied.



This study examines Nir as a case study to explain shrinkage patterns in such settlements and situate them within broader urban shrinkage literature.



Theoretical Framework



The study engages four perspectives on shrinkage.



First, Urban-Rural Interaction views shrinkage as functional disconnection. Following Han et al. (2023), small cities decline when they lose their intermediary role between rural hinterlands and larger urban centers. Administrative upgrading without strengthening this role traps settlements between rural and urban identities.



Second, Urban Flows Theory (Chen et al., 2025) treats cities as nodes dependent on flows of population, capital, and information. Shrinkage occurs when cities experience persistent net outflows, linking decline to unequal spatial structures.



Third, Critical Policy Analysis (Ferreira et al., 2024) argues shrinkage can result from growth-oriented policies themselves. Administrative upgrading may create unrealistic expectations, undermine traditional economies, and generate bureaucratic burdens that unintentionally trigger decline.



Fourth, the Ecological Approach emphasizes environmental drivers. Chen et al. (2023) show climate change, ecological degradation, and resource depletion can directly cause shrinkage, especially where agriculture forms the economic base.



Methodology



The study used a qualitative approach based on adapted grounded theory. Participants were selected purposively using maximum variation sampling. Data came from 17 in-depth unstructured interviews with residents (12) and local officials (5). Theoretical saturation was reached after the fifteenth interview and confirmed with two additional interviews.



Analysis followed inductive thematic analysis. Initial open coding produced 215 primary codes, later grouped into 28 concepts and 10 main themes. In a second stage, themes were interpreted against urban shrinkage literature to identify distinctive characteristics of small upgraded settlements. Credibility was strengthened through member-checking with five participants, triangulation using interviews, observations, and official documents, and independent coding by two researchers.



Study Area



Nir covers 338.7 hectares and lies 80 kilometers south of Yazd. It received city status in 1983 under administrative reclassification policies. Despite periods of relative stability, evidence indicates long-term structural shrinkage. Population declined roughly 17 percent between 1991 and 2011, while local health records suggest a decline closer to 40 percent. The share of elderly residents doubled over 30 years, and 63.5 percent of residents over age ten are economically inactive.



Findings



Findings fall into three categories: background factors, inertia factors, and consequences.



Background Factors include prolonged drought and environmental decline, identified as the initial trigger. During the 1999–2000 water year, severe drought damaged wells, qanats, and agricultural productivity. Because the local economy depended heavily on agriculture and livestock, water decline translated directly into economic stagnation. Service deterioration followed, particularly in education, with falling enrollment and increasing multi-grade classrooms. Migration gradually became culturally normalized, especially among youth, where leaving increasingly symbolized social mobility and prestige. Administrative restructuring in 2008 further weakened Nir’s regional importance by reducing its population base and political status.



Inertia Factors refer to barriers preventing adaptation. A widespread sense of hopelessness emerged among both farmers and younger residents. Many participants described the future of the city pessimistically. In addition, weak solidarity among residents and conflict between local actors undermined collective action and effective decision-making.



Consequences include sustained out-migration, labor shortages, population aging, and vacant housing. Around 40–45 percent of municipal employees commute from outside the city. Many permanent residents are elderly people whose children have migrated. Roughly 65 percent of housing units are vacant or used seasonally, creating temporary summer population increases while leaving the city economically stagnant during the rest of the year.



Self-Reinforcing Shrinkage Cycle



Shrinkage in Nir operates as a self-reinforcing cycle rather than a linear process. Drought weakened agriculture, which caused economic decline and migration. Migration further deepened stagnation through reduced demand, weaker services, labor shortages, and aging populations. Administrative restructuring reduced access to resources, while hopelessness and weak solidarity limited local capacity for collective adaptation. Outcomes such as vacant housing and aging populations do not simply reflect shrinkage but actively intensify it.



Discussion and Theoretical Contributions



Findings show that shrinkage in Nir differs from the classical industrial-city model. Consistent with Jennifer Robinson (2013), the case highlights how small settlements remain marginalized in urban theory despite offering important insights into uneven spatial development. Administrative upgrading without structural changes in power relations may intensify peripheralization rather than promote development.



The study offers four contributions. First, it introduces Post-Upgrade Shrinkage, where decline emerges almost simultaneously with administrative upgrading rather than after long-term growth. Second, it distinguishes Organic Peak from Nominal Peak, arguing statistical urbanization can raise expectations without creating real capacities. Third, it proposes an Institutional-Ecological Shrinkage Cycle, showing how environmental decline, economic fragility, and institutional weakness reinforce each other. Fourth, it repositions small upgraded settlements within the urban-rural continuum, arguing places like Nir are neither fully urban nor rural.



The central policy question is therefore not whether settlements should be upgraded, but under what ecological, economic, and institutional conditions upgrading can produce sustainable development rather than accelerate shrinkage.
