Figure 3. Methodology for development of framework.
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.
