Méthodologie d'évaluation des stocks de carbone des sols
Le projet ' Puits de carbone PSA-ONF ' a débuté en 1998 et vise à séquestrer le carbone à travers le reboisement de pâturages dégradés et la gestion durable de la forêt native. La fazenda São Nicolau, propriété de l'entreprise ONF Brasil et lieu d'accueil du projet, se situe au au nord de l'Etat du Mato Grosso, Brésil. L'Office National des Forêts (ONF) réalise un bilan quinquennal du carbone émis et stocké à travers le projet. Pour cela, il faut identifier les sources d'émissions de gaz à effet de serre et mettre au point des méthodes permettant l'évaluation du carbone stocké dans la biomasse aérienne et souterraine et les sols. Plusieurs études se sont intéressées au stockage dans la biomasse. En revanche, les données sur le sol sont peu nombreuses et souvent imprécises. Or, le sol est un compartiment majeur puisqu'il stocke plus de carbone que la végétation et l'atmosphère. L'objectif de l'étude était donc de mettre en place une méthodologie de mesure des stocks de carbone dans les sols, en priorité sur les parcelles reboisées, en s'appuyant sur les recommandations et les méthodologies mises en œuvre au niveau international.

The Biosphere
"What Darwin did for life through time, Vernadsky did for life through space on a geological scale." --Lynn Margulis This classic 1926 book is the first sustained expression of the idea, now widely accepted, that life is a geological force. It founded the field of biogeochemistry and is one of the seminal works in what is now known as Gaia theory. This edition, the first unexpurgated English translation, is fully annotated for the modern reader.

The Coastal Zone
CONCERNS ABOUT THE HEALTH of the environment have become firmly embedded in the public's list of vital issues confronting present and future generations. The emergence of environmental issues as a significant part of the societal agenda can be traced to the 1960s and 1970s, although threats to the world ecosystem were identified much earlier. In The Coastal Zone, John and Winona Vernberg, the preeminent scholars on the southeastern coastal environment, encourage the general public to gain a more in-depth understanding of environmental science, especially as it pertains to the future of our treasured coastal communities. Using case studies of the southeastern coast, the Vernbergs provide an overview of the ecological characteristics of the coastal zone and urge readers to become aware of environmental consequences resulting from human disturbances such as chemical and biological contamination and habitat alterations. With the rise of urbanization and an ever-increasing population, coastal communities are being subjected to intense multiple stresses resulting from conflicting demands for use of finite resources. In order to save these limited resources for the benefit of present and future generations, the Vernbergs argue that local citizens need to understand the interaction between ecological, economic, and social factors and become actively involved in determining effective resource management policies.
