Book Description
Cette publication réponds au souci des décideurs à définir de zones de modulation intra parcellaire et à identifier au sein d'un bassin agricole les zones présentant le plus grand potentiel pour la mise en place d'une démarche d'agriculture de précision. L'originalité de cette approche repose sur l'étude de la variabilité des sols (le pattern) et non de la valeur de réflectance. Cela permet de surmonter un des problèmes récurrents de l'étude des sols par télédétection qui est le nombre de facteurs influençant cette mesure. Sous l'hypothèse que le "vrai pattern" du sol correspond à celui qui est temporellement stable, une méthode permettant d'identifier les images où ce pattern est présent à l'échelle parcellaire est proposée. La source de cette variabilité est ensuite expliquée Le vrai pattern confronté à des cartes de rendement intra-parcellaire ont permis d'apporter des éléments de réponse aux relations entre pattern du sol et celui du rendement A l'échelle d'un bassin versant et pour permettre aux décideurs de prioriser les zones de démarche d'une agriculture de précision, une méthode de classification en zones de variabilité ayant une signification agronomique est proposée.

Book Description
This book is devoted to Agroecological Crop Protection, which is the declension of the principles of agroecology to crop protection. It presents the concepts of this innovative approach, case studies and lessons and generic keys for agroecological transition. The book is intended for a wide audience, including scientists, experimenters, teachers, farmers, students. It represents a new tool, proposing concrete keys of action on the basis of feedbacks validated scientifically. Beyond the examples presented, it is therefore of general scope and proposes recommendations for all temperate and tropical cropping systems. It contributes to the training and teaching modules in this field and it is an updated information support for professionals and a teaching aid for students (agronomy, crop protection, biodiversity management, agroecology).

Book Description
In view of the massive change in the area of distribution of many world biota across classical biogeographical realms, and of the drastic restructuring of the biotic components of numerous ecosystems, the Scientific Committee on Problems of the Environment (SCOPE) decided at its general Assembly in Ottawa, Canada, in 1982 to launch a project on the 'Ecology of Biological Invasions'. Several regional meetings were subsequently organized within the framework of SCOPE, in order to single out the peculiarities of the invasions that took place in each region, the behaviour of their invasive species and the invasibility of their ecosystems. Most noteworthy among such workshops were one in Australia in August 1984, one concerning North America and Hawaii in October 1984, and one dealing with southern Africa in November 1985. A leitmotiv of these workshops was that most of the invasive species to those regions were emanating from Europe and the Mediterranean Basin, inadvertently or intentionally introduced by man. It was therefore considered as a timely endeavour to organize the next regional meeting in relation to this region. The workshop on 'Biological Invasions in Europe and the Mediterranean Basin' was held in Montpellier, France, 21 to 23 May 1986, thanks to the financial support of SCOPE and of the A.W. Mellon Foundation, and the logistic facilities of the Centre National de la Recherche Scientifique (C.N .R.S.).

Book Description
The 2010 State of the Forest report (SOF) benefited from financial support from the European Union, the United States, Germany, France and UNESCO. It represents the collaborative effort of over 100 individuals from a diversity of institutions and the forestry administrations of the Central African countries. The SOF process began with the selection and definition of indicators relevant to monitoring the state of forests in Central Africa. The indicators are structured around three thematic areas: (i) forest cover; (ii) management of production forests; and (iii) conservation and biodiversity. They are presented in a hierarchical structure at the regional, national and management unit (i.e. logging concessions and protected areas) levels. The indicators were vetted by a representative panel of stakeholders of forest management in Central Africa. The indicators are used to guide an annual data collection process carried out between April and August by national groups of four to ten individuals working within the forestry administrations. The data reported on in the 2010 SOF were primarily collected in 2009 and 2010. Results were validated in national workshops attended by government officials as well as representatives of environmental NGOs, the private sector and development projects. The data provided an important basis for the authors of the 11 chapters of the 2010 SOF, which were under the coordination of a scientific committee of international renown. A final workshop was held 29-30 March, 2011 in Douala to review a draft report. Following amendments based on comments from a wide audience of experts the final layout was completed.

Book Description
The book provides comprehensive information on possible applications of remote sensing data for hydrological monitoring and modelling as well as for water management decisions. Mathematical theory is provided only as far as it is necessary for understanding the underlying principles. The book is especially timely because of new programs and sensors that are or will be realised. ESA, NASA, NASDA as well as the Indian and the Brazilian Space Agency have recently launched satellites or developed plans for new sensor systems that will be especially pertinent to hydrology and water management. New techniques are presented whose structure differ from conventional hydrological models due to the nature of remotely sensed data.
