The book "Metabolism of Urban Food Systems" offers a comprehensive analysis of the complex relationships between urban food and urban development. It highlights the challenges arising from the neglect of urban food systems and their impact on the economic and social well-being of city residents. By examining six essential flows within the food system – land, water, energy, goods, capital, and employment – it provides a deep understanding of the dynamics of urban food supply. Using a case study of Cairo, these flows are analyzed through flow maps and spatial representations to illustrate the interactions between resources and the spatial development of the city. The book is aimed at decision-makers, academics, and professionals in urban planning, offering valuable insights and policy recommendations for designing sustainable food systems.
