Applying Circulating and Ecological Sphere (CES) Concept for Post-Pandemic Development: A Case of Hingna Tahsil, Nagpur (India)

: COVID-19 has become one of the most signiﬁcant events in the history of globalization. The prolonged ‘lockdown’ adopted across various countries in the world as a countermeasure for containing the spread of the virus profoundly brought forth socio-economic and infrastructural vulnerabilities in urban as well as rural parts of India. While urban and rural areas have been greatly studied with respect to the environment, human health, safety, livelihoods, associated risks, etc., in the context of pandemics, many of these studies seldom accommodate their interdependency as a pragmatic approach to planning. This is observed to be primarily due to the dynamic and diverse nature of interactions coupled with the development disparities between rural and urban areas, thereby adding complexity to development decision making. The present study, therefore, applies the lens of the circulating and ecological sphere (CES), introduced by the Japanese government for the localization of resource ﬂows between urban–rural regions, to consider possible alternative development approaches to achieve smooth transitions during pandemics through the case study area located in Hingna tahsil in the Nagpur Metropolitan Area, India. The methodology uses the critical examination of rural–urban linkages amidst the crisis through key-informant surveys involving representatives from local governments. Using this feedback and spatial analysis tools, the research identiﬁes probable entry points in post-pandemic regional planning. The research contributes to understanding the impact of spatial development during pandemics through ground-based evidence. The ﬁndings from this research highlight the need to manage rural dependencies on urban areas and underline the potential of the rural–urban linkage as an approach, acknowledged and emphasized through CES, for managing such regional-scale hazards. The investigation concludes with the discussion and future research scope for achieving the pronounced needs reﬂected through the study.


Introduction
The recent coronavirus (COVID-19) pandemic wreaked havoc around the world. The disease not only led to a standstill in the global economies [1] but also aggravated health and livelihood vulnerabilities. The initial outbreak of COVID-19 or the SARS-CoV-2 virus was reported in one of the prominent urban centers of China-the Wuhan district [2]-by December 2019, and the virus was reported to spread indiscriminately across various countries later. By March 2020, COVID-19 was declared a global public health emergency [3]. Several studies have been carried out to understand the relationship of the pandemic with a wide array of factors including environment, climate, and ecology, to mention a few, but there is still a lack of consensus among the research community about the spread of COVID-19 [4]. The interim guidance report by the WHO [5] made sphere [21]. Thus, applying the lens of CES for post-pandemic development creates opportunities for synergy between various efforts towards achieving the sustainability and resilience of human settlements. Therefore, this paper contemplates applying the frame of CES with a particular emphasis on the perspective of rural-urban linkages for managing the interdependencies between these regions to reduce rural vulnerabilities in the light of pandemics. By analyzing the rural-urban dependencies, this paper proposes a development approach in line with the fundamentals of CES for achieving an effortless transition as opposed to a collapse during such crises.
Hingna tahsil, which forms the rural part of Nagpur district (Maharashtra State, India), was selected as the case study area and analyzed during April 2021 of the COVID-19 pandemic for its dependency on Nagpur city. The study was carried out using mixed methods including a literature study, secondary data analysis, key-informant interviews and spatial analysis. The constraint of primary data points and more reliability on the secondary database (open government database and data from the district census handbooks) due to the pandemic restrictions were two of the limitations of the study. This paper follows a standard structure, beginning with an introduction in Section 1. Section 2 establishes a brief theoretical background about CES, rural-urban linkages and the COVID-19 crisis in Nagpur, followed by Section 3, which details the study area and the methods used to conduct the study. Section 4 presents and analyzes the results of the study, followed by Section 5, which discusses the analysis, concluding with Section 6, which lays the foundation for the future scope of the study.

Circulating and Ecological Sphere (CES) and Rural-Urban Linkages
The concept of CES was introduced by the Japanese government in 2018 to synergize the existing efforts for resilience and sustainability in regions. CES was later promoted internationally to serve as a base for policy formulation [21]. The idea of CES represents a decentralized self-reliant society implementable at various scales. The concept adopts an integrated policy approach incorporating (a) a low-carbon society, (b) resource circulation and (c) living in harmony with nature based on rural-urban linkages as one of the key parameters [21]. Theoretically, CES encourages links between different spatio-sectoral dimensions to achieve its objectives [22]. Although being geographically dispersed and discretely governed, urban and rural areas are recognized to be closely associated with each other through diverse spatial linkages and sectoral interdependencies [23]. These linkages could be defined as symbiotic flows occurring between urban areas and their surrounding rural hinterlands including, but not limited to, people, goods, waste, finance or information [24][25][26]. In essence, the urban areas can be perceived as nodes offering services, communication technologies, knowledge networks and an overall association with national and global infrastructure [27], whereas rural areas can be perceived as the providers of food, water, energy, raw materials and other ecosystem services [28]. Although urban and rural areas are interdependent, rural areas are often observed to be lagging in their developmental trajectories as compared to their urban counterparts [29]. Migration from rural areas to the cities is one factor among several that leads to widening gaps in the prosperity of the two regions, particularly in developing countries [30]. A critical incentive offered by CES is that it encourages the creation of sustainable linkages between urban and rural regions based on gauging the existing flows, including migration [23]. It emphasizes that resources, whether goods, people, finances or knowledge, should be circulated at appropriate scales. In essence, CES proposes the establishment of new linkages between urban environments and their corresponding rural counterparts to promote the circulation of resources for realizing sustainable development goals and at the same time advocating appropriate levels of decentralization.
The importance of linkages has been well-acknowledged for offering a coordinated frame for development by UN-Habitat in 1976 in its first conference [31] and later by the Sustainability Development Goals [32] as well as the New Urban Agenda [33]. Recently, UN-Habitat proposed "enhanced prosperity of regions" as one of its four focus areas in its draft strategic plan, and to realize this objective, guiding principles for urban-rural linkages (URL GP 2019) [34] were formulated for advanced integrated territorial development. The framework for action encourages concrete policies and practices through locally grounded interventions. With the advent of the pandemic, UN-Habitat also published an issue briefly outlining relevant urban-rural linkage principles for COVID-19-relevant actions [35], indicating the role of linkages in managing pandemics. However, approaches for preparing a framework of development strategies and localized action plans based on these guidelines are still being investigated.

Rural-Urban Linkages and COVID-19: A Literature Overview
At the beginning of the pandemic, the epidemiological models predicted that COVID-19 would spread faster in urban metropolitan areas than in the rural areas [36]. In theory, lower population density should make the risk of COVID-19 transmission lower in rural areas. However, at a later stage, rural areas of India had a larger share of COVID-19 cases compared to urban areas, particularly during the months of March to June 2021 [37]. While the abysmal state of preparedness in urban areas was highlighted throughout the pandemic, a more distressing scenario could be observed emerging from the rural areas. A large part of this scenario could be attributed to mass migration in the first wave and the gradual revoking of the lockdowns in the second wave [13,17]. The governments were caught unprepared by the exodus from cities resulting from the imposition of lockdowns, compounded by the out-migration due to several other factors of economic and ecological distress-including extreme weather conditions and natural disasters [37]. At a regional level, migration or commuting is identified as one of the crucial links between urban and rural areas [30]. The flow of people as a resource from rural to urban areas benefiting both rural populations in terms of opportunities and income and urban population in terms of workforce availability can be understood while analyzing migration as a linkage parameter. The importance of migration as one of the critical links between rural and urban areas during the pandemic has also been highlighted through various case studies in India [17,38,39]. Through these studies, it was noted that migrants were essentially forced to return to their hometowns, either due to irregular income owing to pandemicinduced restrictions or safety concerns [40]. Throughout the literature related to COVID-19 and urban planning, authors have argued over the post-pandemic regional dynamics and whether the rural-urban systems will function as usual or are headed towards a new normal. Food insecurity was also noted to be one of the push factors triggering movement in certain areas [19,41], indicating that migration links are closely associated with supply chains. Although several other complex issues act as the drivers for regional development, understanding the underlying dynamics of migration and commute links reflects as imperative while planning for an effective response to the crisis [42].
Undoubtedly, COVID-19 imposed stress on the existing public health sector. Although the rapid spread of COVID-19 has often been associated with the unavailability of basic services and related infrastructure [43], access to higher-order services, particularly healthrelated services, remained one of the primary reasons prompting the relocation of rural residents to the urban limits [44]. The unavailability of health infrastructure, diagnostic centers and clinics in remote rural areas prompted convalescents to move to urban centers [40] where the state-run infrastructure was concentrated, thereby increasing the risk of spread. However, cases have been documented where affected people could not reach the facilities in time due to the unavailability of adequate health care and inaccessibility to transport routes or required transport options. As a response to this unavailability, the health care and the digital infrastructures have been widely discussed in the literature relating to COVID-19 and planning, emphasizing the emerging need for strengthening digital infrastructure to promote health care. The concepts of telehealth and mobile health care also started gaining recognition for better services in remote areas [45,46]. However, it primarily requires stronger physical connectivity down to the remote regions [42]. Another challenge while dealing with the pandemic was the supply chain. A large amount of literature related to COVID-19 and supply chains primarily centered around food security issues due to disrupted supply chains. The supply chain losses were largely dependent on the duration of lockdowns rather than the strictness [47]. However, it is apparent that supply chain disruptions due to the imposed lockdowns had far-reaching effects, particularly on agricultural markets. Several factors such as demand and supply fluctuations, logistics and infrastructure risks, biological and environmental risks and most importantly, financial risks, significantly impacted supply chains [48]. All these factors entail the interrogation of the nature of urban-rural interactions amidst crisis scenarios, particularly the dynamics underlying the highlighted three components of commute and migration, health-service capacities and transport infrastructures.

Case Study Area
This study was conducted at the tahsil level during the period of April 2021 to substantiate the emergent demands for spatial development [15] in regions. A tahsil is a local unit of administrative division, which comprises several towns and villages. For this study, Hingna tahsil, an emerging industrial suburb of Nagpur city, was selected to analyze its relationship with Nagpur city during the pandemic. One of the biggest tahsils located in the south-western part of Nagpur city, the Hingna tahsil covers an area of 942.79 sq. km. With a population of 242,198 and 28,603 households, the tahsil consists of 150 villages and seven census towns [49]. Figure 1 shows the location map of Hingna tahsil with respect to Nagpur city in Nagpur district (Maharashtra State, India). strengthening digital infrastructure to promote health care.

A tahsil is a local unit of administrative division, which comprises several towns and villages. For this study, Hingna tahsil, an emerging industrial suburb of Nagpur city, was selected to analyze its relationship with Nagpur city during the pandemic.

With a population of 242,198 and 28,603 households, the tahsil consists of 150 villages and seven census towns [49]. Figure 1 shows the location map of Hingna tahsil with respect to Nagpur city in Nagpur district (Maharashtra State, India).  The growth of Nagpur city is mainly observed toward the south and south-western parts owing to the presence of industries and the MIHAN Cargo Hub in the transitional area between Nagpur city and Hingna tahsil. The Maharashtra state highway, passing directly through the tahsil, and the National Highway 6 and 7, which is the broad-gauge railway line passing in the close vicinity of the tahsil, promotes rural-urban interactions, which is evident from the rapid development in this particular direction. Nagpur city largely receives agricultural commodities including cotton, soybean, ragi, jowar, gram followed by toor and wheat as well as industrial labor from Hingna. The concentration of census towns of Hingna tahsil near the boundaries of Nagpur city ( Figure 1) is an indicator that significant interchanges are facilitated at the rural-urban boundaries of Hingna tahsil and Nagpur city.

COVID-19 Scenario in the Case Study Area
Despite the first active COVID-19 case being reported in (Kerala state) India around the first week of January 2020, Nagpur city reported its first case in the last week of March 2020m and the subsequent rise in cases peaked around the first week of September 2020. As commonly observed during the countrywide lockdowns, Nagpur too witnessed panic buying and mass migration [50][51][52]. A surge in cases remained unobserved in the rural areas of Nagpur district, including the villages of Hingna tahsil, during the first wave of the pandemic. However, with the imposition of the first lockdown, a decent number of migrants were observed leaving Nagpur city in the direction of Hingna tahsil. With the rising cases in the city, lockdowns continually put pressure on all the service providers as well as the enforcement authorities when people tried to stock essentials by violating the norms and needlessly venturing out [17,19]. At the same time, migrating daily wage workers and commuters presented yet another set of challenges. Thus, the response to the crisis was not only limited to managing lockdowns and health infrastructures but also making provisions for migrant workers during the first wave of the pandemic.
Around the last week of December 2020, despite the rising number of cases, the implementation of lockdowns had reasonably managed the surge [53], thereby encouraging governments to revoke the lockdowns. With the gradual phases of 'unlocking', the intrastate and interstate borders opened, and a steady rise in cases could again be observed [54], which peaked during the months of April and May 2021 and led Nagpur city, including the case study area, into the second wave of the pandemic. Hingna tahsil observed a steep rise in cases during this period. As travel and businesses started operating, increased mobility was noted as a major cause of rising COVID-19 cases [55,56] which was also evident in the case of Hingna tahsil as the influx of the asymptomatic 'reverse migrants' and commuters started returning to work [57].

Selecting Indicators
Building on the literature review in Section 2, the service delivery links, particularly health service delivery, physical links and movement links, emerged as critical while dealing with the pandemic and hence were focused on throughout the analysis in this paper. Past studies have also highlighted inter-relationships between the above-identified linkage parameters (Figure 2), indicating that the strong physical links between rural areas and parent cities form crucial components that support ease of movement as well as service delivery [58]. As was observed in the case study region, during pandemic times, service delivery also determined the frequency of movement.
For each identified parameter of linkages between rural and urban areas, a range of indicators were identified and assembled based on the modified ranking method [59], with values calculated or assigned at the village level. These values were then scaled and aggregated. The selected indicators represent important facets of the linkage parameters that have been identified, and their inter-relationships are elaborated upon in Figure 2 based on the experiences in Nagpur. Although the study was inevitably constrained by the availability of primary data due to the pandemic restrictions, the secondary database from the latest census report of 2011 was used as a support. Based on the three parameters of physical, movement and health service delivery links between rural and urban areas, four indicators and twelve sub-indicators, as presented in Table 1, were identified for analyzing rural dependence on cities.

Data Collection
The secondary data for this study were obtained from reputable sources such as the District Census Handbook (DCHB) 2011 [50] of Nagpur and the Open Government Database and was substantiated with the primary information gathered through telephonic interviews with the key informants from the gram (village) panchayats during the period of April 2021. The interviews were carried out using the purposive sampling method. These data, however, had limitations considering the (lower) availability of the key persons owing to the spread of pandemics in the concerned villages and the restrictions imposed thereby. Out of the 35 g panchayats and 20 clustered gram panchayats, a total of 32 were surveyed through telephonic interviews with key informants to gauge the situations during the pandemic under selected parameters.

Data Construction
The variables so obtained from the identified datasets were observed to have diverse values as well as measurement units. This posed a challenge while analyzing and comparing these variables. Therefore, normalizing the datasets to minimize errors resulting from divergent units was considered a prerequisite for the analysis. For this purpose, the study adopted the standardization method of proportioning the datasets at the village level and rescaling the variables to obtain comparable results from the available database. This kind of statistical rescaling method is widely used to generate comparable datasets. With the rescaled results, the relative index of each parameter was obtained, establishing the degree of rural dependence on urban areas. The critical datasets were then mapped with the ArcGIS version 10.5 software to understand the spatial component and its influence during the crisis.

Secondary Data
The datasets were rescaled and proportioned with respect to the number of villages qualifying the respective criteria. For instance, the graph plotted in Figure 3 indicates the percent number of villages having direct access to transport and health infrastructure and the percent number of villages that needed to commute to gain access to the respective facilities. The component of literacy under technological capacity was rescaled based on the percent number of villages having a population literacy rate over 50% as a minimum qualifying criterion. After rescaling the data, it was observed that there was a typical distribution of sub-indicators. As is evident from Figure 3, more than 50% of the villages needed to commute for health-related concerns rather than education and employment due to the unavailability or no direct access to health care services. This was reaffirmed while analyzing direct access to health care infrastructures, wherein less than 25% of the villages had direct access to COVID-19 care health centers, and less than 20% of the villages had direct access to any alternative health care. On the contrary, adaptive infrastructures such as schools or community halls were conveniently available in more than 90% of the villages for the immediate quarantine of the people with COVID-19. Although direct access to pucca and semi-pucca roads was available for more than 50% of the villages, direct access to transport options such as buses and other para-transit options was available in less than 35% of the villages, which meant moving to cities or towns demanded access to private transport options. The analysis of technological capacity for knowledge dispersion and remote consultancy, work, etc., indicated that the availability of power supply, mobile and internet services as well as operational literacy was found in more than 75% of the villages. direct access to transport options such as buses and other para-transit options was available in less than 35% of the villages, which meant moving to cities or towns demanded access to private transport options.

Primary Survey Result
The primary surveys were mainly structured around the issues that were being faced at the village level regarding the provision of health care facilities and other losses incurred due to the pandemic as well as due to the consequent restrictions that were imposed. Out of the 32 telephonic interviews conducted with the key informants from different gram panchayats of Hingna tahsil, 27 reported that restrictions imposed due to the COVID-19 lockdowns had caused a lot of difficulties for the residents rather than the disease itself. Although in the beginning there were fewer cases, the administrative authorities were able to make adequate provisions for quarantine and mobile health care facilities. However, with the surge in cases, health care obligations and the financial necessities made it imperative for the residents to commute to nearby urban areas. Figure 4 represents the overall response from the key informants of different gram panchayats regarding the fundamental issues faced by the village residents during the pandemic.  Serious concerns were expressed regarding the loss of employment, business and farm produce followed by inadequate health care facilities and the need to accommodate incoming migrants with respect to quarantine shelters and similar facilities. The general relation of A leading to B and B leading to C could thus be substantiated and articulated as mentioned below: Unavailability of services (A) → Commute (B) → Spread (C),

Spatial Analysis
The villages that absolutely needed to commute for any purpose were mapped as shown in Figure 5 based on the weightage assigned, as indicated in Table 2. The mapping was carried out using the weighted overlay method with the weights assigned based on the feedback from the key informants. It was observed that around 30% of the villages required the residents to commute more than 10 kms for work, to access health care or reach out to market intermediaries, and so on. Since the commute, which was not an issue during the pre-pandemic situation, was an essential part of their day-to-day lives and the implementation of lockdowns with the advent of COVID-19 disturbed the order of their routine activities, these areas incurred losses, not only in terms of lives but also financial losses. As the villages were overly dependent on the urban areas for medical facilities as well as for employment and to sell their produce, the implementation of lockdowns had exponential effects on the losses (Figure 4) that were incurred. As there were no intermediate service regions, the residents had to directly access the urban limits. Serious concerns were expressed regarding the loss of employment, business and farm produce followed by inadequate health care facilities and the need to accommodate incoming migrants with respect to quarantine shelters and similar facilities. The general relation of A leading to B and B leading to C could thus be substantiated and articulated as mentioned below:

Based on the observations and expressed concerns, it was noted that there was a pr nounced need to limit the excessive dependencies and the need for commuting, partic larly in the events of crises such as the COVID-19 pandemic.

These villages reported issues relat to loss of income due to the unavailability of direct access to markets as well as the lack support infrastructure and suffered a severe setback during the lockdown period due their dependence on these areas.

Discussion
The COVID-19 pandemic was not merely a serious public health concern but a trigger for socio-economic crises. The plights of migrant laborers rendered jobless overnight due to the lockdown and subsequent mass exodus towards their native rural areas pushed the local as well as regional governments towards a humanitarian crisis. At the same time, the disruption in the supply chain leading to food and medicine shortages was yet another challenge to be dealt with. The pandemic reflected the unpreparedness of current health systems as well. The need to rethink the functioning of the existing rural-urban interactions to accommodate shocks has frequently been highlighted through different media including newspaper articles, general public interviews and research publications. Promoting digitalization and remote health-related consultation from urban areas for better correspondence with rural areas are among a few solutions that are being rigorously discussed. However, investigating the way these interactions are laid out necessitates researching alternate perspectives for the management of such crises. Towards this direction, the concept of CES that recognizes the importance of decentralized self-reliant societies at different scales, facilitating interchanges to foster holistic development in a region, can potentially be a valid approach. The key findings through this research were that (1) although stronger rural-urban linkages foster development, they also stimulate a higher level of dependencies, which during such emergencies are not necessarily desirable. (2) It was recognized that the organization of links between rural and urban areas may notably influence the order of rural functionality. For instance, establishing nodes within a cluster of villages could enable hierarchy in the rural-urban transect. These nodes could then be selectively diverted or deactivated in the event of an emergency. (3) It could also be understood that the performance of linkages may have a significant impact on self-reliance at the local level. This means that the more access and connectivity there is, the less self-sufficiency there is.
The linkages between urban and rural areas are often dynamic, and the recent pandemic proved that the nature of interactions varies depending on the circumstances. Therefore, novel approaches for sustaining, channeling, organizing and conditioning these rural-urban links need to be explored to manage the interdependencies between urban areas and their rural counterparts. This could be achieved by dispersing the centralized functions, in this case, into distinct areas which do not have direct access to the respective services. Such nodes would establish the said hierarchy wherein a cluster of villages can access the respective nodes to avail the emergency services and the node could be directly connected to the nearby towns or the city for higher-order services. Such nodes can facilitate health care units, markets, financial institutions, trade and education centers as well as intermediate repository establishments such as godowns, warehouses, and so on. This would encourage the easy monitoring as well as the efficient management of links, thereby paving a way for smoother transitions during the events of a crisis.
As recommended by the Urban-Rural Linkage Guiding Principles [34] and supported by the principles of CES, the potential of small and medium towns can be harnessed to act as mediators between villages and cities. Decentralization at the local level to manage resources could be utilized to achieve effective development transitions. The capacities of intermediate towns to act as nodes for response and coordination could be developed. These towns can also be developed as trade and education hubs with markets and recreational facilities. Smaller belts of land could be acquired and developed with the help of private role players. Ensuring an uninterrupted supply of power, clean water, quality road infrastructure and transport options along with appropriate telecommunication systems, as in the case of Hingna tahsil, such clusters may attract investments through incentives. From the point of view of urbanization, service clusters may have the potential to provide attractive alternative destinations for city-bound rural migrants as well. Such nodes not only serve as service intermediaries but also create employment opportunities leading to lesser strain on the primary cities, thereby alleviating urban poverty. At the same time, they are likely to be more intimate with the rural areas and therefore can play a critical role in reducing the overall rural poverty as well.
The approach to post-crisis 'recovery' is rooted in the assertion that societies have the capacities to determine the merits and degrees of returning to the previous state. This study advances the theory that adopting the principles of CES for post-pandemic development can offer a holistic approach to overall regional development. Although theoretically incorporating the concept appears to be a viable solution, it entails high levels of participation across all stakeholders to have a clearer understanding and a common agreement on choices of returning or proceeding to a new normal. Further, development programs have massive, long-lasting impacts and therefore need to be meticulously planned to ensure desired social and economic benefits while strengthening the existing systems to deal with future shocks. As reported by OECD [60], post-pandemic planning requires the generation of co-benefits for social equity, environment and human health. The literature regarding the COVID-19 and urban planning has often emphasized long-term infrastructure investments in digital as well as health care infrastructure in remote areas, which may also support rural development and advance bi-directional flows through rural-urban links. In a way, the pandemic has also reiterated the importance of a decentralized and self-reliant society. Amidst crises such as the pandemics, a decentralized spatial layout with manageable interactions may prove more effective than the existing layouts. However, further research in this area needs to be conducted to support this perception. Since the scope for this study was limited to these three elements, other elements of linkages have not been entirely explored and can be looked at as a way forward. At the same time, only the rural dependencies and impacts have been emphasized and explored in this paper; urban issues also need to be investigated through the lens of linkages. Although the study is specific to the COVID-19 pandemic, it presents an approach that can be tailored and adopted for various other regional-scale emergencies.

Conclusions
Every major crisis brings opportunities to rethink the structure of a system and make it more resilient to future shocks. This research asserts the notion that post-pandemic planning would call for the realignment of rural-urban interactions and the recognition of the importance of administration at the lowest level, both encouraged through the CES. Although CES exhibits tremendous potential for post-pandemic development, addressing the challenges related to critical service enhancement in peri-urban and rural regions still needs to be researched. One of the key findings from this research was that strong rural-urban linkages encourage more dependencies of rural areas on the city, and during emergencies such as pandemics, severe reliance on urban amenities and facilities proves undesirable. Ideally, diffusing the urban-rural binary with effective rural-urban linkages for an integrated development appears to be an archetypal solution. However, achieving this goal is an intensive task with respect to time as well as resources. Contrarily, managing linkages by maintaining a certain degree of hierarchy and re-directing the flows, particularly during times of crises such as the COVID-19 pandemic, emerges as a feasible solution. Thus, CES emerges as an approach to materializing the management of rural-urban linkages. This was also demonstrated through the case study presented in this paper.
Regional development approaches and urban planning models have not yet fully evolved in the context of pandemics, while the need for the same has been highlighted through several studies. Such attempts are also not evident in the case of cities in developing countries. This article, therefore, is a unique attempt in that direction by proposing an alternative approach to the provision of services at urban and regional levels to effectively respond to emergency scenarios through spatial planning. Although the idea of decentralization has been reiterated in the context of managing linkages between rural and urban areas, the provision of intermediate service clusters for developing a seamless continuum between the urban and rural areas calls for a more detailed investigation which can be looked at as the future scope of this study. As it is said, 'Diseases shape cities' and some of the most iconic developments in urban planning and management systems such as 'sanitation' were developed in response to public health crises of cholera outbreaks. Similarly, COVID-19 is also likely to leave an enduring mark on the present systems.
