Rural-urban food, nutrient and virtual water flows in selected West African cities by Drechsel, Pay, Graefe, S., Fink, M. Pdf

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.

Characteristics of Urban and Peri-urban Agriculture in West Africa by Imogen Bellwood-Howard,Volker Häring,Hanna Karg,Regina Roessler,Johannes Schlesinger,Martina Shakya Pdf

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 Security of Water, Food, Energy and Liveability of Cities by Basant Maheshwari,Ramesh Purohit,Hector Malano,Vijay P. Singh,Priyanie Amerasinghe Pdf

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.

Integrating Food into Urban Planning by Food and Agriculture Organization of the United Nations,University College London Press Pdf

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.

Integrating Food into Urban Planning by Yves Cabannes,Cecilia Marocchino Pdf

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 how food is produced, processed, packaged, transported, marketed, consumed, disposed of and recycled in our cities. While there is a growing body of literature on the topic, the issue of planning cities in such a way they will increase food security and nutrition, not only for the affluent sections of society but primarily for the poor, is much less discussed, and much less informed by practices. This volume, a collaboration between the Bartlett Development Planning Unit at UCL and the Food Agricultural Organisation, aims to fill this gap by putting more than 20 city-based experiences in perspective, including studies from Toronto, New York City, Portland and Providence in North America; Milan in Europe and Cape Town in Africa; Belo Horizonte and Lima in South America; and, in Asia, Bangkok and Tokyo. By studying and comparing cities of different sizes, from both the Global North and South, in developed and developing regions, the contributors collectively argue for the importance and circulation of global knowledge rooted in local food planning practices, programmes and policies.

The Water, Food, Energy and Climate Nexus by Felix Dodds,Jamie Bartram Pdf

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 State of African Cities 2014 by UN-HABITAT Pdf

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.

Urban Agriculture by Craig Pearson Pdf

Most of us live in cities. These are becoming increasingly complex and removed from broad-scale agriculture. Yet within cities there are many examples of greenspaces and local food production that bring multiple benefits that often go unnoticed. This book presents a collection of the latest thinking on the multiple dimensions of sustainable greenspace and food production within cities. It describes the diversity of 'urban agriculture' and seeks a balanced representation between the biophysical and the social. It deals with urban agriculture across scales - from indoor plants to farm-scale filtration of greywater. A range of examples and initiatives from both developed and developing countries is described and evaluated.

Principles of Sustainable Soil Management in Agroecosystems by Rattan Lal,B.A. Stewart Pdf

With the use of high-level soil management technology, Africa could feed several billion people, yet food production has generally stagnated since the 1960s. No matter how powerful the seed technology, the seedling emerging from it can flourish only in a healthy soil. Accordingly, crop yields in Africa, South Asia, and the Caribbean could be double

Water for Food in a Changing World by Alberto Garrido,Helen Ingram Pdf

There is not enough water globally for all the things humans need and want water to do for us. Water supply bubbles are bursting in China, the Middle East and India with potentially serious implications for the global economy and for political stability. Even the United States is depleting groundwater on average 25% faster than it is being replenished. Our thirst for water grows with our population, but the amount of fresh water available on Earth is fixed. If we assume "business as usual" by 2050 about 40% of the projected global population of 9.4 billion is expected to be facing water stress or scarcity. With increasing climate variability being predicted by global climate models, we are likely also to have more people without adequate water more of the time, even in water-rich regions. Irrigation productivity rose dramatically over the past 40 years as a result of the Green Revolution. However, even if we disregard the environmental impacts caused by that revolution, we are no nearer to achieving global food security than we were 40 years ago, as every time we come close to filling the food production gap population growth and ecosystem decline associated with water diversions to human purposes set us back. Our natural and agricultural ecosystems are trying to tell us something. This book pursues these overarching themes connecting to water and food production at global and regional scales. The collection offers a comprehensive discussion of all relevant issues, and offers a wide-ranging discussion with the aim of contributing to the global debate about water and food crises.

Urban Life-Worlds in Motion by Hans Peter Hahn,Kristin Kastner Pdf

Urban agglomerations host the most vital and creative societies. This applies particularly to Africa, where cities have the highest growth rates world-wide and where the urban population is younger than anywhere else. Urban life-worlds are the basis for the development of new lifestyles and new cultural phenomena. Based on empirical ethnographic research, this book presents case studies that enhance our understanding of the dynamics of urbanity in Africa and beyond - by envisioning cities as crossroads where cultures, biographies and networks meet.

Food waste minimization and circularity for optimizing urban food system resilience by Simon, D.,Fauzi, D.,Drechsel, Pay,Melati, K.,Prain, G.,Jintarith, P.,Cavalleri, S. A. E.,Kangogo, D.,Osborne, M. Pdf

As urbanization increases, meeting the challenges of urban food supply and food security requires coherent and holistic strategies. Attention too often focuses solely on best practices without addressing the required behavior change. This policy brief highlights the importance of minimizing food loss and waste, which accounts for some 30% of current global production, in order to link and achieve SDGs 2, 11 and 12. The strategy comprises four interrelated elements, namely adopting holistic and circular planning perspectives; facilitating urban and peri-urban farming; integrating innovative behavioral interventions; and providing enabling environments. The G20 has the capacity to act rapidly, without the need for major capital investment, thereby also providing leadership to the entire international community.
