Sustainable agriculture is a rapidly growing field aiming at producing food and energy in a sustainable way for humans and their children. Sustainable agriculture is a discipline that addresses current issues such as climate change, increasing food and fuel prices, poor-nation starvation, rich-nation obesity, water pollution, soil erosion, fertility loss, pest control, and biodiversity depletion. Novel, environmentally-friendly solutions are proposed based on integrated knowledge from sciences as diverse as agronomy, soil science, molecular biology, chemistry, toxicology, ecology, economy, and social sciences. Indeed, sustainable agriculture decipher mechanisms of processes that occur from the molecular level to the farming system to the global level at time scales ranging from seconds to centuries. For that, scientists use the system approach that involves studying components and interactions of a whole system to address scientific, economic and social issues. In that respect, sustainable agriculture is not a classical, narrow science. Instead of solving problems using the classical painkiller approach that treats only negative impacts, sustainable agriculture treats problem sources. Because most actual society issues are now intertwined, global, and fast-developing, sustainable agriculture will bring solutions to build a safer world. This book series 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.

Phosphorus (P) is a finite resource which is essential for life. It is a limiting nutrient in many ecosystems but also a pollutant which can affect biodiversity in terrestrial ecosystems and change the ecology of water bodies. This book collects the latest information on biological processes in soil P cycling, which to date have remained much less understood than physico-chemical processes. The methods section presents spectroscopic techniques and the characterization of microbial P forms, as well as the use of tracers, molecular approaches and modeling of soil-plant systems. The section on processes deals with mycorrhizal symbioses, microbial P solubilization, soil macrofauna, phosphatase enzymes and rhizosphere processes. On the system level, P cycling is examined for grasslands, arctic and alpine soils, forest plantations, tropical forests, and dryland regions. Further, P management with respect to animal production and cropping, and the interactions between global change and P cycling, are treated.

Phosphorus is essential for life, yet is often the element most limiting for biological productivity. Although most organisms take up phosphorus in an inorganic form, organic forms frequently dominate in soils and aquatic systems. Up to this point, the role of organic phosphorus and mechanisms for its dynamics have been poorly understood. However, recent advances in research have shed new light on the subject and this book brings together these advances. It covers the transformation and characterization of organic phosphorus in both terrestrial and aquatic systems. It will attract a broad range of scientists from several disciplines.

It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.

About twenty years ago, there was a recognition in Europe that real benefits would flow from coordinating the manner in which food composition tables were produced in the various countries of Europe. Subsequent development of computerised nutritional data bases has further highlighted the potential advantages of working together. Such cooperation could lead to improved quality and compatibility of the various European nutrient data bases and the values within them. This realisation was one of the driving forces behind the development of the Eurofoods initiative in the 1980's when those people in Europe interested in data on food composition began working together. This initiative received further impetus with the establishment of the Eurofoods-Enfant Concerted Action Project within the framework of the FLAIR (Food-Linked Agro-Industrial Research) Programme of the Commission of the European Communities. It was quickly recognised that the draft guidelines for the production, management and use of food composition data which had been prepared under the aegis of INFOODS (International Network of Food Data Systems, a project of the United Nations University), would be especially applicable to the objectives of the Concerted Action. The guidelines have been written by two recognised experts. Many people associated with FLAIR Eurofoods-Enfant have added constructive criticism and advice to that offered previously by those associated with INFOODS. Thus the guidelines are backed by a consensus in the community of those responsible for the production and use of food composition tables and nutrient data bases.

Urban Disasters and Resilience in Asia presents the latest information on the intensity and frequency of disasters. Specifically, the fact that, in urban areas, more than 50% of the world's population is living on just 2% of the land surface, with most of these cities located in Asia and developing countries that have high vulnerability and intensification. The book offers an in-depth and multidisciplinary approach to reducing the impact of disasters by examining specific evidence from events in these areas that can be used to develop best practices and increase urban resilience worldwide. As urban resilience is largely a function of resilient and resourceful citizens, building cities which are more resilient internally and externally can lead to more productive economic returns. In an era of rapid urbanization and increasing disaster risks and vulnerabilities in Asian cities, Urban Disasters and Resilience in Asia is an invaluable tool for policy makers, researchers, and practitioners working in both public and private sectors. Explores a broad range of aspects of disaster and urban resiliency, including environmental, economic, architectural, and engineering factors Bridges the gap between urban resilience and rural areas and community building Provides evidence-based data that can lead to improved disaster resiliency in urban Asia Focuses on Asian cities, some of the most densely populated areas on the planet, where disasters are particularly devastating

Climate-Smart Landscapes: Multifunctionality in Practice is about a 'landscape approach' to achieving multiple climate, social, development and environmental objectives. It builds on climate-smart landscapes as a growing platform and pathway towards achieving multi functionality. This book in 27 chapters draws strongly from practices, methods, examples and considerations for applying landscape approaches to achieve multifunctional outcomes and in particular, address the complex challenge of climate change. http://asb.cgiar.org/sites/default/files/count/click.php?id=2
