The purpose of this book is to set out the key lessons learned and to provide recommendations and guidance based on existing cases and examples for a wide range of actors involved in urban food systems. In particular, the aim is for this publication to serve as a sourcebook for local decision-makers, policy advisors, urban planners, specialists, practitioners and others involved in urban and peri-urban agriculture (UPA). The sourcebook is also for those involved in the design and implementation of production schemes, planning of urban food strategies, and policies concerning agriculture in urban and peri-urban areas.

Urban agriculture (UA) is a dynamic concept that comprises a variety of livelihood systems ranging from subsistence production and processing at the household level to more commercialized agriculture. It takes place in different locations and under varying socio-economic conditions and political regimes. The diversity of UA is one of its main attributes, as it can be adapted to a wide range of urban situations and to the needs of diverse stakeholders. This paper aims to provide pertinent information on profitability and sustainability of UA to a wide audience of managers and policymakers from municipalities, ministries of agriculture, local government, Non-Governmental Organizations (NGOs), donor organizations and university research institutions. It aims to highlight the benefits of linkages between agriculture and the urban environment, leading to a more balanced understanding of the conflicts and synergies. It examines how UA can contribute substantially to the Millennium Development Goals (MDGs), particularly in reducing urban poverty and hunger (MDG 1) and ensuring environmental sustainability (MDG 7).

Sustainability rests on the principle that we must meet the needs of the present without compromising the ability of future generations to meet their own needs. Starving people in poor nations, obesity in rich nations, increasing food prices, on-going climate changes, increasing fuel and transportation costs, flaws of the global market, worldwide pesticide pollution, pest adaptation and resistance, loss of soil fertility and organic carbon, soil erosion, decreasing biodiversity, desertification, and so on. Despite unprecedented advances in sciences allowing to visit planets and disclose subatomic particles, serious terrestrial issues about food show clearly that conventional agriculture is not suited any longer to feed humans and to preserve ecosystems. Sustainable agriculture is an alternative for solving fundamental and applied issues related to food production in an ecological way. While conventional agriculture is driven almost solely by productivity and profit, sustainable agriculture integrates biological, chemical, physical, ecological, economic and social sciences in a comprehensive way to develop new farming practices that are safe and do not degrade our environment. In that respect, sustainable agriculture is not a classical and narrow science. Instead of solving problems using the classical painkiller approach that treats only negative impacts, sustainable agriculture treats problem sources. As most actual society issues are now intertwined, global, and fast-developing, sustainable agriculture will bring solutions to build a safer world. This book gathers review articles that analyze current agricultural issues and knowledge, then propose alternative solutions. It will therefore help all scientists, decision-makers, professors, farmers and politicians who wish to build a safe agriculture, energy and food system for future generations.

Currently, spatial analysis is becoming more important than ever because enormous volumes of spatial data are available from different sources, such as GPS, Remote Sensing, and others. This book deals with spatial analysis and modelling. It provides a comprehensive discussion of spatial analysis, methods, and approaches related to human settlements and associated environment. Key contributions with empirical case studies from Iran, Philippines, Vietnam, Thailand, Nepal, and Japan that apply spatial analysis including autocorrelation, fuzzy, voronoi, cellular automata, analytic hierarchy process, artificial neural network, spatial metrics, spatial statistics, regression, and remote sensing mapping techniques are compiled comprehensively. The core value of this book is a wide variety of results with state of the art discussion including empirical case studies. It provides a milestone reference to students, researchers, planners, and other practitioners dealing the spatial problems on urban and regional issues. We are pleased to announce that this book has been presented with the 2011 publishing award from the GIS Association of Japan. We would like to congratulate the authors!

This book examines the role and position of urban agriculture in the spatial and functional structure of cities in the Global South. In the face of dynamic urbanisation and negative consequences of climate change, one of the key challenges is not only how to provide food for the ever-growing urban population but also how to achieve urban sustainability and simultaneously reduce the negative impact of cities on the natural environment. These problems are particularly urgent in the metropolises of the Global South that are experiencing the greatest population growth while struggling with increasing social inequalities and the resulting uneven distribution of resources. Examining the role that urban agriculture can play in addressing these challenges, this book draws on three case study cities: Havana, Singapore and Kigali. The case studies, differing in socio-economic, spatial, political and environmental terms, exemplify diverse characteristics of urban agriculture in different geographical conditions. Drawing on fieldwork conducted in each city, the book also provides a unique perspective on the constraints in the development of urban agriculture and the use of its full potential for urban sustainability. This book will appeal to students and scholars, as well as decision makers, interested in the issues of urban sustainability, food security, spatial development and alternative food systems.

This book provides a comprehensive synthesis of current knowledge of the potential and challenges associated with the multiple roles, use, management and livelihood contributions of indigenous vegetables in urban agriculture in sub-Saharan Africa. There has been growing research and policy effort around urban agriculture in the region over the last two decades, but never has it been integrated with work on under-researched crops such as indigenous vegetables. These species have multiple advantages, including low input requirements, adaptability to African environments, high nutritional value and marked biodiversity, cultural and local food security significance. Yet they are overlooked in the modern world, where recent emphasis has been directed to growing a limited range of exotic crops, both for internal markets and for export to developed country markets. This book provides evidence that, in spite of this neglect, in many African cities indigenous vegetables are still widely used, cultivated and marketed. It goes on to consider their potential to contribute to income generation and poverty alleviation of the growing numbers of urban dwellers in sub-Saharan Africa, whilst promoting urban greening and sustainability. Based on critical analysis of the debates it presents a multidisciplinary analysis of the realities and future opportunities.
