Eating locally and developing an urban-rural food continuum is a rapidly evolving movement. Integration of multi-functional forms of agriculture - termed New Forms of Urban Agriculture (NFUA) - could be a critical adaptation to strengthen this movement and for the sustainability of cities. While NFUA have the potential to provide diverse benefits to humans, there is an absence of reliable empirical data on the scale and impact of urban resources on NFUA which has a profound impact on its viability and sustainability. In this book, we shift the focus from how NFUA have potential to impact the urban system to investigate the potential impacts of urban resources on NFUA. Access to resources such as land, labour, clean water, etc. are major barriers to enter the agriculture sector in the cities; the chapters in this book present projects or reviews recent research on the subject from different cities in the world. This edited volume offers critical perspectives from diverse disciplines, expertise, and geographic contexts related to the actual and potential role of urban and peri-urban agriculture in the developing and the developed world where forms, adaptations, and debates around NFUA vary distinctively. Using and urban ecology lens, the book provides empirical evidence of how urban resources of land, water/waste, labour, and biodiversity impact NFUA.
