Nano- and micro-sized natural fibers of vegetable origin are fully biodegradable in nature. However, the nano- and micro-sized synthetic fibers are fully man-made. Fiber-reinforced composites composed of stiffened fiber and matrix are well-known engineering materials. Fiber-reinforced materials have been used in industrial production. Natural fibers can be obtained from many sources in nature such as wool, sisal, ramie, kenaf, jute, hemp, grass, flax, cotton, coir, bamboo and abaca, banana, and sugarcane bagasse. Artificial fibers have been produced from more stiff materials such as glass, single-walled carbon nanotubes, double-walled carbon nanotubes, carbon, aramid, boron and polyethylene (PE). The cyclic reusability of materials is an important qualification in protecting the environment from waste pollution. Three important factors can be mentioned in terms of material properties in the recycling process. The first factor is ""the rate of cyclic usage,"" the second one is ""less material loss in each recycle,"" and the last one is ""the role of waste products in the self-renewal of ecosystem."" In engineering area, the usage of waste materials has taken into account in production of composite materials. The use of waste materials as particulate-type composite production is also possible in the industry. Fiber-reinforced materials can be grouped into two categories: ""the natural fiber-reinforced materials"" and ""the artificially produced fiber-reinforced materials."" Finally, we conclude that this book consists of mainly summarized three subject headings within the two specific book subsections : The first group contains the main subjects related to the natural and artificial fibers obtained by literature review; second, experimental and numerical studies are made in order to perform the necessary arrangements in the production stages and to establish a decision mechanism on the specification of the technical properties of the fiber-reinforced composites. The third group of studies focused on the use of sustainable bio-composites and recycled textile wastes as reinforcements in construction.

Depuis une dizaine d'années, l'idée que la sauvegarde de notre planète passe par le développement économique et le partage équitable des bénéfices s'est largement répandue. Dans le cas des ressources naturelles renouvelables, quel est donc ce « bon usage » qui permettrait de concilier préservation des écosystèmes et bien-être des populations locales ? Les études de cas en milieu tropical rassemblées dans cet ouvrage soulignent la diversité et la compléxité des systèmes mis en place pour gérer ces ressources. Produites de manière sponténée par les écosystèmes, elles peuvent être utilisées par les sociétés humaines sur le monde d'un simple prélèvement (chasse, cueillette, pêche) ou bien faire l'objet d'une activité destinée à accroître leur potentiel (extractivisme, agroforesterie). À travers ces études de cas, trois grandes questions d'intérêt général sont abordées : les interactions entre artification et anthropisation ; le rôle de la gestion sociale locale ; les relations entre science et aménagement. L'expérience montre que le bon usage ne peut se référer à un paradigme immuable : il consiste surtout à réaliser un équilibre précaire dans un contexte écologique et social en continuelle transformation.

Le développement durable et sa traduction en terme de participation des acteurs locaux aux choix d'avenir des territoires dans lesquels ils vivent ou travaillent, sont devenus des sujets d'actualité. Parmi les méthodes pour mettre en place des démarches participatives autour de la gestion durable des ressources naturelles renouvelables, la modélisation d'accompagnement est particulièrement originale. Cet ouvrage a pour objectif de familiariser le lecteur avec la démarche de modélisation d'accompagnement, en présentant la posture scientifique qui la fonde, ses méthodes et ses outils, et la place particulière des modèles. Il explique également comment intégrer plusieurs échelles de décision, prendre en compte les jeux de pouvoir, et enfin comment évaluer les effets sur les personnes associées à la mise en œuvre de cette démarche. Cet ouvrage s'appuie sur les exemples concrets issus de 27 cas étudiés par le collectif de chercheurs et sur des outils pédagogiques. Il est destiné aux chercheurs dans le domaine du développement rural et des ressources renouvelables, ainsi qu'aux étudiants et enseignants.
