Book excerpt: This state of the environment (SOE) report is a companion volume to the federal science assessment entitled "Nutrients and their impact on the Canadian enviornment", which was authored by Patricia Chambers, et al. This state of the environment (SOE) report on nutrients looks at how the Canadian environment is being affected by nitrogen and phosphorus compounds that are released as a result of human activities. The report describes the mechanisms by which nutrients affect the environment, assesses their impact on the environment especially through enrichment, and their potential for future damage, and outlines the major sources of these compounds. It also looks at what has been done and what can be done to alleviate these problems.

Book excerpt: Canada's National Programme of Action for the Protection of the Marine Environment from Land-based Activities (NPA) is a partnership between federal, provincial and territorial governments aimed at addressing the interface between fresh and salt waters, river basins and coastal environments to prevent marine pollution from land-based activities and to protect habitat in coastal zones of Canada. NPA focusses on addressing problems within 14 categories under 2 broad themes: contaminants; and physical alteration and destruction of habitat. This document describes each of the NPA categories and provides examples of ongoing actions.

Book excerpt: Grâce à la grande diversité des organisations biologiques, notamment des bio-systèmes forestiers, la Caraïbe fait partie des 34 Hotspots actuels de la biosphère. C'est une aire géographique extraordinaire pour l'évolution du vivant, car les différents canevas régionaux - géomorphologiques, pédologiques, climatiques - associés aux îles, à la bordure continentale et à l'isthme ont induit une pluralité de biotopes. Ce qui a conditionné autant de communautés floristiques et faunistiques, de physionomies et de paysages. Tous les écosystèmes de l'espace intertropical y sont représentés. Néanmoins, les sociétés successives depuis la découverte des Amériques, tout en utilisant les ressources offertes par les écosystèmes du Nouveau Monde, les ont architecturés et les paysages notamment végétaux du présent sont des témoins pertinents de ce processus. L'érosion biologique régulière, consubstantielle à la croissance des productions humaines, reste, encore aujourd'hui, un danger pour le développement de ces territoires : bien des aspects floristiques et faunistiques sont encore inconnus. En quelque sorte, dans cette partie du monde la recherche est " insaturée ". Le colloque de décembre 2005 sur les " Écosystèmes forestiers des Caraïbes " organisé par le Conseil Général de la Martinique et piloté scientifiquement par l'Université des Antilles et de la Guyane (sous la direction de Philippe Joseph), a mis en relief la problématique de la biodiversité des terres qui enserrent la mer des Caraïbes. Et, plus largement, celle de la planète tout entière confrontée au changement climatique et à ses conséquences à long terme sur les milieux anthropisés, singulièrement les modifications des frontières écosystémiques et les espèces envahissantes. La mise en perspective des données obtenues par les chercheurs de champs disciplinaires variés, qui relèvent des sciences exactes, humaines, juridiques et économiques, a fourni une somme importante de connaissances et de méthodes. Celles-ci permettent d'éclairer la décision publique, en particulier pour améliorer les outils de gestion et de planification des forêts caribéennes. Par cette initiative, le Conseil Général de la Martinique, à l'instar de son président, a indiqué la voie qui devrait permettre, à long terme, une conservation et une valorisation de toutes les diversités biologiques. Au regard des modifications climatiques futures, en effet, le potentiel évolutif des bio-systèmes doit être, par tous les moyens, préservé.
