Les pesticides font aujourd’hui l’objet d’enjeux environnementaux considérables. Dès 1999, le ministère chargé de l’Écologie a mis en place le programme de recherche « Évaluation et réduction des risques liés à l’utilisation des pesticides ». Dans ce cadre, 57 projets de recherche ont été lancés afin d’accroître la connaissance des risques et d’aider les acteurs du domaine à mettre en œuvre des actions pour les réduire.Cet ouvrage présente les avancées majeures de ce programme à travers quatre thématiques principales : transferts de pesticides et réduction de la contamination de l'environnement ; effets des pesticides et réduction des impacts sur les organismes et les écosystèmes ; pratiques agronomiques innovantes pour réduire l’utilisation des pesticides ; accompagnement des acteurs pour réduire les risques liés aux pesticides.Les décideurs, porteurs de politiques publiques, professionnels du monde agricole ou encore gestionnaires de l’environnement y trouveront des éléments pour estimer les risques liés à l’utilisation de ces produits et agir en faveur de pratiques agricoles plus économes en pesticides. Les enseignants mais aussi les étudiants accéderont à une synthèse des connaissances, étoffée de nombreuses références bibliographiques. Enfin, l’ouvrage identifie certaines lacunes scientifiques de la problématique et ouvre la réflexion sur de futures pistes de recherche.

This volume contains most of the scientific contributions to the workshop ``Prediction of Agricultural Nonpoint Source Pollution: Model Selection and Application'' held in Venice, in the historic Ca' Vendramin Calergi, in June, 1984. Other contributions of specialists who were not able to attend the workshop have also been included in an attempt to make the work more complete.It is hoped that this collection will be useful to planners who operate in the field of agricultural diffuse source pollution, since several contributions are state-of-the-art presentations and others are specialized stud

This book examines the dynamics underpinning the implementation of Zimbabwe's fast track land reforms. By utilising ethnographic data gathered in central Zimbabwe, the book goes beyond the polarised debates which dominated scholarship in the earlier period to highlight the changing livelihoods occasioned by the land reform. The book argues that despite the challenges faced by the newly resettled farmers, the land reform has allowed landless and land-short peasants access to land and other natural resources which were previously enclosed to them under a bi-modal agrarian structure inherited from colonialism.

Water pollution control has been a top environmental policy priority of the world's most developed countries for decades, and the focus of significant regulation and public and private spending. Yet, significant water quality problems remain, and trends for some pollutants are in the wrong direction. This book addresses the economics of water pollution control and water pollution control policy in agriculture, with an aim towards providing students, environmental policy analysts, and other environmental professionals with economic concepts and tools essential to understanding the problem and crafting solutions that can be effective and efficient. The book will also examine existing policies and proposed reforms in the developed world. Although this book addresses and has a general applicability to major water pollutants from agriculture (e.g., pesticides, pharmaceuticals, sediments, nutrients), it will focus on the sediment and nutrient pollution problem. The economic and scientific foundations for pollution management are best developed for these pollutants, and they are currently the top priorities of policy makers. Accordingly, the authors provide both highly salient and informative cases for developing concepts and methods of general applicability, with high profile examples such as the Chesapeake Bay, Lake Erie, and the Gulf of Mexico Dead Zone in the US; the Baltic Sea in Northern Europe; and Lake Taupo in New Zealand.

Constructed wetlands (CWs) are engineered phytoremediation ecotechnologies. Herein, the two main biotic components, namely, plants and the bacterial community, work synergistically to remove a wide range of pollutants from wastewater. CWs have been used as sole treatment systems or as integrated modules within other types of wastewater-treatment plants (WWTPs), e.g., as tertiary treatment units. This Special Issue and Book gathers and appraises recent research outcomes regarding natural wetlands (i.e., mangroves) and engineered wetlands (constructed/floating systems), and highlights the underlying pollutant-degradation pathways and mechanisms for a wide range of organic and inorganic contaminants.

Improving water quality is consistently ranked as a top environmental concern in OECD public opinion surveys. The key challenges for policy makers in addressing water quality issues in agriculture are to reduce water pollution while encourage benefits, such as maintaining aquatic life. This book examines linking policies, farm management and water quality. It looks at recent trends and prospects for water pollution from agriculture and the implications of climate change. It assesses the costs and benefits of agriculture's impact on water systems, and presents a series of case studies. Finally the report provides a set of recommendations for countries for meeting the challenge of improving agricultural water quality.

Global climate change is a natural process that currently appears to be strongly influenced by human activities, which increase atmospheric concentrations of greenhouse gases (GHG). Agriculture contributes about 20% of the world's global radiation forcing from carbon dioxide, methane and nitrous oxide, and produces 50% of the methane and 70% of the nitrous oxide of the human-induced emission. Managing Agricultural Greenhouse Gases synthesizes the wealth of information generated from the GRACEnet (Greenhouse gas Reduction through Agricultural Carbon Enhancement network) effort with co
