Book Description
In 4 out of 5 cities in developing countries, wastewater is used to cultivate perishable crops for urban markets. Such practices create a health risk but provide important livelihood benefits. This study through an analysis of 53 cities in developing countries, contributes to understanding the factors that drive wastewater use. The main drivers are (1) increasing urban water demand without wastewater treatment causing pollution of irrigation water sources; (2) urban food demand favoring agriculture close to cities where water sources are polluted; and (3) lack of cheaper, similarly reliable or safer water sources. Poverty, which constrains the infrastructure needs of urbanization, is an added factor. The study makes policy recommendations stressing on, effectively applying the WHO guidelines, linking investments in water supply with sanitation for maximum beneficial impact on water pollution, and involving actors at both the national and local level, for water quality improvements and health risk reduction

Book Description
Many countries experience lack of harmony among economic development, environmental management and human health. As a consequence, public health, the integrity of ecosystems, and the efforts to reach environmental sustainability, have been adversely affected. The complexity, frequency and magnitude of those impacts is increasingly parallel to the t

Book Description
The relationships between soils, microbes and humans are of crucial relevance in the tropics, where plant stress and microbial activity are exacerbated. This volume of Soil Biology presents the living component of tropical soils, showing how it is shaped by environmental conditions and emphasizing its dramatic impact on human survival and well-being. Following an introduction to the specificities of tropical soils and of their microbial communities, the biological aspects of soil management are examined, dealing with land use change, conservation and slash-and-burn agriculture, the restoration of hot deserts, agroforestry and paddy rice cultivation. As they are of particular relevance for tropical agriculture, symbioses of plants and microbes are thoroughly covered, as are the biodegradation of pesticides and health risks associated with wastewater irrigation. Lastly, traditional soil knowledge is discussed as a key to our sustainable presence in this world.

Book Description
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.

Book Description
In an increasingly global community of researchers and practitioners, new technologies and communication means have made the transfer of policies from one country or region to another progressively more prevalent. There has been a lot of attention in the field of public administration paid to policy transfer and institutional transplantation. This book aims to create a better understanding of such transfers in the water management sector. These include the adoption of modern water management concepts, such as integrated water resources management and forms of water governance, which are strongly promoted and sometimes also imposed by various international organizations. Transfers also occur within the scope of development aid or for the purpose of creating business opportunities. In addition, many research organisations, consultancies and governmental agencies are involved in cross-border work. The purpose of this book is therefore to present practical examples of the transfer of modern water management from one locality to another and to critically discuss the transferability of policy and governance concepts by analysing the contextual needs and factors. Case studies are included from North America, Europe, the Middle East and Asia. It is argued that in many cases context matters in water management and that there is no panacea or universal concept that can be applied to all countries or regions with different political, economic, cultural and technological contexts. Yet it is also shown that some countries are facing pressing and similar water management issues that cut across national borders, and hence the transfer of knowledge may be beneficial.

Book Description
This book focuses on participation of the public and private sectors in urban water management and on the role of water pricing. It discusses in-depth topics such as public choices of urban water service management; dynamics of privatization and regulation of water services; adoption of water demand instruments; impacts of price and non-price policies on residential water demand; quality of water services; lessons from not-for-profit public-private partnerships; and critical examinations of models and projections of demands in water utility resource planning in England and Wales. Appropriateness of water prices and tariffs in achieving socially desirable outcomes is also analyzed and a global survey of urban water tariffs is approached with a focus on sustainability, efficiency and fairness. This book was originally published as a special issue of the International Journal of Water Resources Management.

Book Description
Knowledge of Africa’s complex farming systems, set in their socio-economic and environmental context, is an essential ingredient to developing effective strategies for improving food and nutrition security. This book systematically and comprehensively describes the characteristics, trends, drivers of change and strategic priorities for each of Africa’s fifteen farming systems and their main subsystems. It shows how a farming systems perspective can be used to identify pathways to household food security and poverty reduction, and how strategic interventions may need to differ from one farming system to another. In the analysis, emphasis is placed on understanding farming systems drivers of change, trends and strategic priorities for science and policy. Illustrated with full-colour maps and photographs throughout, the volume provides a comprehensive and insightful analysis of Africa’s farming systems and pathways for the future to improve food and nutrition security. The book is an essential follow-up to the seminal work Farming Systems and Poverty by Dixon and colleagues for the Food and Agriculture Organization (FAO) of the United Nations and the World Bank, published in 2001.
