Globally, 30% of the world population lived in urban areas in 1950, 54% in 2016 and 66% projected by 2050. The most urbanized regions include North America, Latin America, and Europe. Urban encroachment depletes soil carbon and the aboveground biomass carbon pools, enhancing the flux of carbon from soil and vegetation into the atmosphere. Thus, urbanization has exacerbated ecological and environmental problems. Urban soils are composed of geological material that has been drastically disturbed by anthropogenic activities and compromised their role in the production of food, aesthetics of residential areas, and pollutant dynamics. Properties of urban soils are normally not favorable to plant growth—the soils are contaminated by heavy metals and are compacted and sealed. Therefore, the quality of urban soils must be restored to make use of this valuable resource for delivery of essential ecosystem services (e.g., food, water and air quality, carbon sequestration, temperature moderation, biodiversity). Part of the Advances in Soil Sciences Series, Urban Soils explains properties of urban soils; assesses the effects of urbanization on the cycling of carbon, nitrogen, and water and the impacts of management of urban soils, soil restoration, urban agriculture, and food security; evaluates ecosystem services provisioned by urban soils, and describes synthetic and artificial soils.

Home Gardens for Improved Food Security and Livelihoods demonstrates how home gardens hold particular significance for resource-poor and marginalized communities in developing countries, and how they offer a versatile strategy toward building local and more resilient food systems. With food and nutritional security being a major global challenge, there is an urgent need to find innovative ways to increase food production and diversify food sources while increasing income-generating opportunities for communities faced with hunger and poverty. This book shows that when implemented properly, home gardens can become just such an innovative solution, as well as an integral part of sustainable food security programs. It provides a conceptual overview of social, economic, environmental and nutritional issues related to home gardening in diverse contexts, including gender issues and biodiversity conservation, and presents case studies from Africa, Asia and Latin America highlighting home gardening experiences and initiatives. The volume concludes with a synthesis of key lessons learned and ways forward for further enhancing home gardens for sustainable food security and development. This book will be a useful read for students and scholars working on local food systems, food security, sustainable development and more broadly development strategy.

‘Homegardens’ are integrated tree–crop–animal production systems, often established on small parcels of land surrounding homesteads, and primarily found in tropical environments. This multi-authored volume contains peer-reviewed chapters from the world’s leading researchers and professionals in this topic. It summarizes the current state of knowledge on homegarden systems, with a view to using this knowledge as a basis for improving both homegardens and other similar multistrata agroforestry systems.

While most of the existing literature on community gardens and urban agriculture share a tendency towards either an advocacy view or a rather dismissive approach on the grounds of the co-optation of food growing, self-help and voluntarism to the neoliberal agenda, this collection investigates and reflects on the complex and sometimes contradictory nature of these initiatives. It questions to what extent they address social inequality and injustice and interrogates them as forms of political agency that contest, transform and re-signify ‘the urban’. Claims for land access, the right to food, the social benefits of city greening/community conviviality, and insurgent forms of planning, are multiplying within policy, advocacy and academic literature; and are becoming increasingly manifested through the practice of urban gardening. These claims are symptomatic of the way issues of social reproduction intersect with the environment, as well as the fact that urban planning and the production of space remains a crucial point of an ever-evolving debate on equity and justice in the city. Amid a mushrooming over positive literature, this book explores the initiatives of urban gardening critically rather than apologetically. The contributors acknowledge that these initiatives are happening within neoliberal environments, which promote –among other things - urban competition, the dismantling of the welfare state, the erasure of public space and ongoing austerity. These initiatives, thus, can either be manifestation of new forms of solidarity, political agency and citizenship or new tools for enclosure, inequality and exclusion. In designing this book, the progressive stance of these initiatives has therefore been taken as a research question, rather than as an assumption. The result is a collection of chapters that explore potentials and limitations of political gardening as a practice to envision and implement a more sustainable and just city.

Combines practical wisdom on ecological design and community-building with a fresh, green perspective on an age-old subject. Activist and urban gardener Heather Flores shares her nine-step permaculture design to help farmsteaders and city dwellers alike build fertile soil, promote biodiversity, and increase natural habitat in their own "paradise gardens." This joyful lifestyle manual inspires readers to apply the principles of the paradise garden--simplicity, resourcefulness, creativity, mindfulness, and community--to all aspects of life. Plant "guerrilla gardens" in barren intersections and medians; organize community meals; start a street theater troupe or host a local art swap; free your kitchen from refrigeration and enjoy truly fresh, nourishing foods from your own plot of land; work with children to create garden play spaces. Flores cares passionately about the damaged state of our environment and our throwaway society. Here, she shows us how to reclaim the earth, one garden at a time.--From publisher description.

Food gardening is becoming increasingly popular, as people look for new ways to live more sustainably and minimize harm to the environment. This book addresses the 21st century trends which bring new challenges to food gardening - anthropogenic climate change, environmental degradation, natural resource scarcity, and social inequity - and explains the basic biological, ecological and social concepts needed to understand and respond to them. Examples throughout the text demonstrate how to successfully use these concepts, while supporting gardeners' values, and their goals for themselves, their communities and the world.
