Impacts of increasing population pressure on food demand and land and water resources have sparked interest in nutrient and water balances and flows at a range of scales. In IWMI Research Report 115, it was tried for the first time to quantify rural-urban food flows for selected cities in Ghana and Burkina Faso to analyse their dependency on food supplied from rural vs. peri-urban vs. urban farming. Both, the urban nutrient and water footprints are closely interlinked. Currently, 80-95 percent of the domestic water used and the nutrients consumed go to waste without treatment or resource recovery. The economic dimensions are significant. Options to reduce the environmental burden by closing the rural-urban water and nutrient cycles are discussed.

The report summarizes key results from surveys carried out on urban and peri-urban agriculture (UPA) in Tamale (Ghana) and Ouagadougou (Burkina Faso) in 2013. The aim was to provide a broad overview of the state of UPA in the study cities and a basis for future research endeavors. The randomized sampling approach used aerial photography to identify 10 sites in different categories of farm in each city. Farmers provided information on their cropping and livestock-rearing activities. There were similarities between the cities, but the differences in the expression of UPA in Tamale and Ouagadougou were more intriguing, as in farm sizes, crops grown and livestock ownership. Farmers were particularly concerned about diminishing access to land in Tamale, where sales by chiefs to private investors were accelerating. In Ouagadougou, formal reallocation of land to homeowners by the state had similarly decreased available farmland. Water availability was a universal concern, and the quality of water used for irrigation was potentially more questionable in Ouagadougou than in Tamale. The results point to the need for further work on uncontaminated, perennial water sources and soil fertility management, alongside focuses on commercialization of animal production, and the legal, political and institutional context of UPA in different West African cities.

The population of cities around the world is growing at an alarming rate, and as a result the landscapes of most cities are going through enormous changes. In particular, fertile agricultural lands at the periphery of cities are being developed without consideration of holistic planning. As such, peri-urban areas, zones of transition from rural to urban land uses located between the outer limits of the urban and the rural environment are experiencing significant losses of agricultural land, increased runoff, and water quality degradation. Concurrently, the demands for water, food and energy are increasing within cities, and unless a balance is struck the liveability of these cities will soon be compromised. The current water and land use changes have serious consequences on lifestyle, environment, health and overall well-being of urban communities. This book therefore helps readers to understand the current issues and challenges and examines suitable strategies and practices to cope with current and future pressures of urbanisation and peri-urban land-use changes. The book examines a number of critical aspects in relation to the future of cities and peri-urban regions, including the suitability of policies and institutions to sustain cities into the future; impact of current trends in land use change, population increase and water demand; long term planning needs and approaches to ensure the secured future for generations ahead; and strategies to adapt the cities and land uses so that they remain viable and liveable. The readership of the book will include policy makers, urban planners, researchers, post-graduate students in urban planning and environmental and water resources management and managers in municipal councils.

The integration of food into urban planning is a crucial and emerging topic. Urban planners, alongside the local and regional authorities that have traditionally been less engaged in food-related issues, are now asked to take a central and active part in understanding the way food is produced, processed, packaged, transported, marketed, consumed, disposed of and recycled in our cities. Despite a growing body of literature on food and cities, the issue of planning cities in such a way they will increase food security and nutrition, not only for the affluent segments of society but primarily for the poor, is much less discussed, and much less informed by practices. This volume intends to fill this gap by putting more than 20 city-based experiences in perspective: Toronto, New York City, Providence and Portland in North America; Cape Town and Ghana in Africa; Milan in Europe; Lima and Belo Horizonte in South America; and, in Asia, Bangkok, Solo and Yogyakarta in Indonesia, and Tokyo. By drawing on cities of different sizes, from regions across the global north and south, in both developed and developing areas, the contributors collectively attest to the importance of global knowledge rooted in local food planning practices, programmes and policies.

Global trends of population growth, rising living standards and the rapidly increasing urbanized world are increasing the demand on water, food and energy. Added to this is the growing threat of climate change which will have huge impacts on water and food availability. It is increasingly clear that there is no place in an interlinked world for isolated solutions aimed at just one sector. In recent years the "nexus" has emerged as a powerful concept to capture these inter-linkages of resources and is now a key feature of policy-making. This book is one of the first to provide a broad overview of both the science behind the nexus and the implications for policies and sustainable development. It brings together contributions by leading intergovernmental and governmental officials, industry, scientists and other stakeholder thinkers who are working to develop the approaches to the Nexus of water-food-energy and climate. It represents a major synthesis and state-of-the-art assessment of the Nexus by major players, in light of the adoption by the United Nations of the new Sustainable Development Goals and Targets in 2015.

The African continent is currently in the midst of simultaneously unfolding and highly significant demographic, economic, technological, environmental, urban and socio-political transitions. Africa’s economic performance is promising, with booming cities supporting growing middle classes and creating sizable consumer markets. Despite significant overall growth, the continent continues to suffer under very rapid urban growth accompanied by massive urban poverty and many other social problems. These seem to indicate that the development trajectories followed by African nations since post-independence may not be able to deliver on the aspirations of broad based human development and prosperity for all. This report, therefore, argues for a bold re-imagining of prevailing models in order to steer the ongoing transitions towards greater sustainability based on a thorough review of all available options. That is especially the case since the already daunting urban challenges in Africa are now being exacerbated by the new vulnerabilities and threats associated with climate and environmental change.
