There has been growing attention paid to urban agriculture worldwide because of its role in making cities more environmentaly sustainable while also contributing to enhanced food access and social justice. This edited volume brings together current research and case studies concerning urban agriculture from both the Global North and the Global South. Its objective is to help bridge the long-standing divide between discussion of urban agriculture in the Global North and the Global South and to demonstrate that today there are greater areas of overlap than there are differences both theoretically and substantively, and that research in either area can help inform research in the other. The book covers the nature of urban agriculture and how it supports livelihoods, provides ecosystem services, and community development. It also considers urban agriculture and social capital, networks, and agro-biodiversity conservation. Concepts such as sustainability, resilience, adaptation and community, and the value of urban agriculture as a recreational resource are explored. It also examines, quite fundamentally, why people farm in the city and how urban agriculture can contribute to more sustainable cities in both the Global North and the Global South.
