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.

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.

Bioenergy is renewable energy obtained from biomass—any organic material that has stored sunlight in the form of chemical energy. Biogas is among the biofuels that can be obtained from biomass resources, including biodegradable wastes like manure, sewage sludge, the organic fraction of municipal solid wastes, slaughterhouse waste, crop residues, and more recently lignocellulosic biomass and algae. Within the framework of the circular economy, biogas production from biodegradable waste is particularly interesting, as it helps to save resources while reducing environmental pollution. Besides, lignocellulosic biomass and algae do not compete for arable land with food crops (in contrast with energy crops). Hence, they constitute a novel source of biomass for bioenergy.Biogas plants may involve both high-tech and low-tech digesters, ranging from industrial-scale plants to small-scale farms and even households. They pose an alternative for decentralized bioenergy production in rural areas. Indeed, the biogas produced can be used in heaters, engines, combined heat and power units, and even cookstoves at the household level. Notwithstanding, digesters are considered to be a sustainable technology that can improve the living conditions of farmers by covering energy needs and boosting nutrient recycling. Thanks to their technical, socio-economic, and environmental benefits, rural biogas plants have been spreading around the world since the 1970s, with a large focus on farm-based systems and households. However, several challenges still need to be overcome in order to improve the technology and financial viability.

This comprehensive volume covers recent studies into agricultural problems caused by soil and water contamination. Considering the importance of agricultural crops to human health, the editors have focused on chapters detailing the negative impact of heavy metals, excessive chemical fertilizer use, nutrients, pesticides, herbicides, insecticides, agricultural wastes and toxic pollutants, among others, on agricultural soil and crops. In addition, the chapters offer solutions to these negative impacts through various scientific approaches, including using biotechnology, nanotechnology, nutrient management strategies, biofertilizers, as well as potent PGRs and elicitors. This book serves as a key source of information on scientific and engineered approaches and challenges for the bioremediation of agricultural contamination worldwide. This book should be helpful for research students, teachers, agriculturalists, agronomists, botanists, and plant growers, as well as in the fields of agriculture, agronomy, plant science, plant biology, and biotechnology, among others. It serves as an excellent reference on the current research and future directions of contaminants in agriculture from laboratory research to field application.
