Available in PDF, EPUB and Kindle. Book excerpt: Travail dans le cadre de la valorisation agricole des boues résiduaires de station d'épuration des eaux usées. L'objectif était d'étudier l'évolution des boues dans le sol du point de vue de la matière organique et de préciser leur effet sur les propriétés physico-chimiques du sol. Dans cette optique, nous avons tout d'abord réalisé l'analyse d'un échantillonage de boues de diverses origines, afin de mettre en évidence d'une part, leurs potentialités fertilisantes, et, d'autre part, l'importance des fluctuations de leur composition en éléments totaux. Dans une deuxième partie, nous avons suivi, à l'aide d'un dispositif respirométrique in vitro, la minéralisation des boues incorporées à un sol de référence [...] Dans un troisième temps notre attention s'est portée sur les modifications des propriétés du sol induites par la présence des boues.

Download or read book Agriculture in Urban Planning written by Mark Redwood and published by Earthscan. This book was released on 2012 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume, by graduate researchers working in urban agriculture, examines concrete strategies to integrate city farming into the urban landscape. Drawing on original field work in cities across the rapidly urbanizing global south, the book examines the contribution of urban agriculture and city farming to livelihoods and food security. Case studies cover food production diversification for robust and secure food provision; the socio-economic and agronomic aspects of urban composting; urban agriculture as a viable livelihood strategy; strategies for integrating city farming into urban landscapes; and the complex social-ecological networks of urban agriculture. Other case studies look at public health aspects including the impact of pesticides, micro-biological risks, pollution and water contamination on food production and people. Ultimately the book calls on city farmers, politicians, environmentalists and regulatory bodies to work together to improve the long term sustainability of urban farming as a major, secure source of food and employment for urban populations.

Available in PDF, EPUB and Kindle. Book excerpt: The use of urban wastewater in agriculture is receiving renewed attention, with the increasing scarcity of fresh water resources in many arid and semi-arid regions of the world. Wastewater is a low-cost alternative to conventional irrigation water, although it may carry health and environmental risks. This book critically reviews experience worldwide of these issues. Emphasis is placed on untreated wastewater use by means of field-based case studies from Asia, Africa, the Middle East and Latin America. It brings together a range of perspectives including economic, health, agronomic, environmental, institutional, and policy dimensions.

Available in PDF, EPUB and Kindle. Book excerpt: This book is a critical guide to conducting investigations under time- and resource-pressured conditions, equipping readers with the key skills and approaches for research designed to influence or inform development policies. Unlike a simple 'how to' guide, Research Skills for Policy and Development also provides a critique of various methods and situates these approaches within 'real life' organisational settings, enabling those working in or studying development to locate, evaluate and use relevant information quickly but rigorously. The successor to Finding Out Fast (SAGE, 1998) it reflects the changes in development management theories and practice over the last seven years, and includes new material and advice on critical use of the web as a resource and research tool. It is essential reading for development managers in NGOs and public sector agencies as well as students of development management and development studies more generally.
