Food, energy, and water (collectively referred to as ‘FEW’) security forms the key to human survival as well as socioeconomic development. However, the security of these basic resources is increasingly threatened due to growing demand. Beyond the widespread implications on public health, Coronavirus disease (COVID-19) has further raised additional challenges for FEW security, particularly for urban populations, as they mainly outsource their FEW demands from rural areas outside their physical boundaries. In light of that, this study reviews existing literature on FEW security to highlight the growing relevance of urban–rural linkages for realizing FEW security, especially against the backdrop of the COVID-19 pandemic. To achieve this, relevant research documents have been identified through Elsevier’s Scopus database and other sources (by applying search equations). The authors have accordingly underlined the necessity of shifting the conventional urban-centric approach to city region-centric development planning for the post-COVID-19 era. To this end, a framework has been suggested for translating physical urban–rural linkages to a partnership enhancing a collective response. The major elements of this framework are the conceptualization of national-level policies to support urban–rural linkages. The framework can play the role of a science–policy–action interface to redesign the FEW system in city regions.

The world’s urban population is expected to nearly double by 2050, making urbanization one of the most disruptive developments of the 21st century. On a global-to-local scale, ensuring a secure and reliable supply of food energy and water (FEW) resources for all humans is a major challenge in such a scenario. While much attention has recently been focused on the concept of FEW security and the interactions between the three sectors, there is no universally acceptable framing of the concept due to the fact that latest studies are mainly focused on individual FEW sectors, with not much investigation into how they interact. This research aims to create a localized framework based on the principles of the emerging concept of the Circulating Ecological Sphere (CES), introduced by the government of Japan, for a limited number of security indicators and dimensions. It began with a thorough study of the relevant literature using the PRISMA method, identification of gaps in local indicators for urban areas in each of the existing frameworks, and the proposal of a new indicator framework that tackles collective FEW security in urban environments is made accordingly. The authors have applied a special mechanism for filtration of this literature dataset in the context of Nagpur City in accordance with data availability and case study context. To test the applicability of the indicator set, it has been applied to the specific case of Nagpur. Both online and offline surveys were conducted to collect data, and subsequently a weighted mean method was adopted to analyze the data and derive values for the indicator set.

The expansion of the online food services (collectively referred to as ‘OFS’) sector has been accelerating at high rates worldwide over the last few years. This sector is widely acknowledged, especially by urban consumers, for making life more convenient. During the strict lockdown following the breakout of the COVID-19 pandemic, the OFS sector saw major growth, as many restaurants and grocery stores turned to the delivery format. Conversely, the sector has also been facing many challenges, which have lasting social, economic, and environmental impacts. Considering this situation, this study carried out a review of existing literature on the social, environmental, and economic impacts of OFS and explored the resilience gaps of this fast-growing food service business. To achieve this, relevant literature was collected through Elsevier’s SCOPUS database and other sources. The authors have documented specific social, environmental, and economic impacts of OFS on consumers and providers. Furthermore, various changes in this sector following the pandemic have also been underlined in this study. A combination of policy actions at the national, local, private sector, and individual levels is crucial to mitigate the adverse impact of OFS; hence, greater resilience will be ensured.
