La FAO a achevé sa première évaluation des ressources forestières mondiales en 1948. À cette époque, son principal objectif était de recueillir des informations sur l’offre de bois disponible pour satisfaire la demande de reconstruction d’après-guerre. Depuis lors, l'Évaluation des ressources forestières mondiales (FRA) est devenue une évaluation complète des ressources forestières et de leur état, de leur gestion et de leurs utilisations, couvrant tous les éléments thématiques de la gestion durable des forêts. Cette dernière, la dernière de ces évaluations, examine l'état et les tendances des ressources forestières au cours de la période 1990-2020, en s'appuyant sur les efforts de centaines d'experts dans le monde. La production de FRA 2020 impliquait également une collaboration entre de nombreuses organisations partenaires, réduisant ainsi le fardeau des rapports pour les pays, augmentant les synergies entre les processus de rapport et améliorant la cohérence des données.Les résultats de FRA 2020 sont disponibles dans plusieurs formats, y compris ce rapport et une base de données en ligne contenant les contributions originales des pays et territoires ainsi que des études documentaires et des analyses régionales et mondiales préparées par la FAO. Je vous invite à utiliser ces matériaux pour soutenir notre cheminement commun vers un avenir plus durable avec les forêts.

L'évaluation des ressources forestières mondiales 2010 (FRA 2010) est l'évaluation la plus exhaustive disponible sur les forêts et la foresterie, tant sur le plan des collaborateurs que de la teneur. FRA 2010 examine la situation actuelle et les tendances récentes d'environ 90 variables, notamment l'étendue, les conditions, les usages et la valeur des forêts et autres terres boisées, dans le but d'évaluer tous les bénéfices découlant des ressources forestières. Des informations provenant de 233 pays et territoires ont été collectées et analysées à quatre reprises. Il s'agit d'un véritable partenariat mondial résultant en données plus satisfaisantes sur les forêts du monde et la foresterie, un processus d'établissement des rapports plus transparent et une meilleure capacité d'analyser les données et de les communiquer.

Le monde progresse-t-il vers la gestion forestiere durable? Cette question a servi de cadre a l'Evaluation des ressources forestieres mondiales 2005 (FRA 2005), la plus exhaustive a ce jour des series de la FAO sur ces evaluations, couvrant 229 pays et zones pour la periode comprise entre 1990 et 2005. Cette publication, le rapport principal de FRA 2005, contient des donnees par pays, fournies par les correspondants nationaux et revisees et regroupees par la FAO, concernant davantage de variables forestieres cles que dans toute autre evaluation precedente. Sur la base de ces resultats, le rapport analyse les progres accomplis vers la gestion forestiere durable. Le present rapport est un ouvrage de reference indispensable pour ceux qui s'interessent a la situation des forets du monde, pour ceux qui participent aux negociations internationales portant sur les forets et pour tous ceux qui sont soucieux de connaitre la contribution des forets au developpement durable."

Geographical Information Systems (GIS) provide an enhanced environment for spatial data processing. The ability of geographic information systems to handle and analyse spatially referenced data may be seen as a major characteristic which distinguishes GIS from information systems developed to serve the needs of business data processing as well as from CAD systems or other systems whose primary objective is map production. This book, which contains contributions from a wide-ranging group of international scholars, demonstrates the progress which has been achieved so far at the interface of GIS technology and spatial analysis and planning. The various contributions bring together theoretical and conceptual, technical and applied issues. Topics covered include the design and use of GIS and spatial models, AI tools for spatial modelling in GIS, spatial statistical analysis and GIS, GIS and dynamic modelling, GIS in urban planning and policy making, information systems for policy evaluation, and spatial decision support systems.

Since 2000, IOM has been producing world migration reports. The World Migration Report 2020, the tenth in the world migration report series, has been produced to contribute to increased understanding of migration throughout the world. This new edition presents key data and information on migration as well as thematic chapters on highly topical migration issues, and is structured to focus on two key contributions for readers: Part I: key information on migration and migrants (including migration-related statistics); and Part II: balanced, evidence-based analysis of complex and emerging migration issues.

The trend in forestry is toward shorter rotations and more complete utiliza tion of trees. The reasons are: (1) financial pressures to obtain rapid returns on the forestry investment made possible by an earlier harvest; (2) enforced harvest of young plantations to maintain a continuing supply of cellulose for mills where wood shortages are experienced; (3) thinning young plantations, both because they were planted too densely initially and because thinning is done where long rotation quality trees are the forestry goal; (4) more intensive utilization is being done using tops and small diameter trees; and (5) there is interest in using young (juvenile) wood for special products because of its unique characteristics and the development of new technologies. The largest present-day source of conifer juvenile wood is from thinnings of plantations where millions of hectares of pine were planted too densely. Because of the better growth rate resulting from improved silviculture and good genetic stock, plantations will need to be thinned heavily. As a result of this trend, young wood makes up an increasingly larger proportion of the total conifer wood supply each year. Large amounts of juvenile wood from hard woods are also currently available, especially in the tropics and subtropics, because of the fast growth rate of the species used, which results in shorter rotations and ess~ntially all juvenile wood.
