In the last decade, governments, international institutions, donors, the private sector,
etc. have shown a renewed interest in agricultural issues in Sub-Saharan Africa (SSA).
This interest came with a strong need for information in countries where the lack of
reliable and timely basic information can be a problem. Thanks to its capacity to observe...
Geospatial information and its derived products, designed to contribute to public agricultural policy making, are not widely used in Africa, and this despite an increase access to satellite imagery and processing tools. This paper is mainly addressed to policy makers concerned by land and agricultural resources management, as a way to show them the...
To date, there is no effective treatment to cure dengue fever, a mosquito-borne disease which has a major impact on human populations in tropical and sub-tropical regions. Although the characteristics of dengue infection are well known, factors associated with landscape are highly scale dependent in time and space, and therefore difficult to monito...
Les informations géospatiales et leurs produits dérivés, conçus pour contribuer à la définition des politiques publiques agricoles, sont peu utilisés en Afrique. Les infrastructures, la formation et les compétences manquent ; les activités de recherche et développement sont dispersées et insuffisantes. Mais, surtout, les besoins restent mal formali...
Geospatial information and its derived products, designed to contribute to public agricultural policy making, are not widely used in Africa. The infrastructure, training and skills are lacking, and
research and development activities are dispersed and inadequate. More importantly, needs are not formalised and technological resources, driven by the...
The Mouth of the Amazon River, considered to be the largest river on Earth, is a geomorphological macro-frontier between two coastal blocks : the Guiana Shield coastal plain (from Amapa to Venezuela) and the North Brazil block (Pará/Maranhão). It also constitutes a vast geological domain that links the Amapa Platform, the Marajo Basin and the Pará/...
The Mouth of the Amazon River, considered to be the largest river on Earth, is a geomorphological macro-frontier between two coastal blocks : the Guiana Shield coastal fringe (from Amapa to Venezuela) and the Para/Maranhao block (North Brazil). It also constitutes a vast geological domain that links the Amapa Platform, the Marajo Basin and the Para...
Highlights: This paper describes the Theia Land Data Centre, its service and data infrastructure, network of scientific expertise centres, product portfolio and main activities. The paper emphasizes in its conclusion the connection between Theia and the Copernicus programme at European level, and the forthcoming Remote Sensing Data Infrastructure n...
Highlights : This paper describes the Spatial Data Infrastructure of the SEAS-OI satellite ground station. The objective of this SDI is to promote the use and to enhance the distribution of satellite data among the scientific community and the public institutions in the Southwest of the Indian Ocean.
Highlights: This paper describes the GEOSUD project which aims to implement a national data and services infrastructure in order to facilitate the use of satellite imagery by the French scientific community and public institutions. This ecosystem of innovation is part of the THEIA Land Data Centre.
Technological tools allow the generation of large volumes of data. For example satellite images aid in the study of spatiotemporal phenomena in a range of disciplines, such as urban planning, environmental sciences, and health care. Thus, remote-sensing experts must handle various and complex image sets for their interpretations. The GIS community...
La renovation legislative des parcs nationaux conduit a s’interroger sur la nature du droit dans les aires protegees. Serait-il concevable de penser la formation d’un droit davantage negocie qu’impose ? La question peut legitimement se poser dans le cas du Parc amazonien de Guyane (PAG), qui integre en zone d’adhesion plusieurs communautes autochto...
In French Guiana a direct receiving facility called "SEAS Guyane" is operating since early 2006, bringing Envisat/Asar and Spot 5 direct receiving capacities for scientific aplications. The Cartam-Sat project introduced in 2009 an original standpoint in satellite data processing praxis of ground stations such as SEAS: it aims at producing from the...
Satellite data sets : SEAS GUYANE DIRECT RECEIVING FACILITY, FRENCH GUIANA-© CNES-Commercial distribution Spot Image SA UMR Context Amazonia's coastal fringe beholds a complex mosaic of ecosystems composed of forests, savannas, mangroves, wetlands, marshes, swamps. These ecosystems are under the influence of the Amazon sedimentary dispersion system...
A global systematic sampling scheme has been developed by the UN FAO and the EC TREES project to estimate rates of deforestation at global or continental levels at intervals of 5 to 10 years. This global scheme can be intensified to produce results at the national level. In this paper, using surrogate observations, we compare the deforestation esti...
Les rapports des hommes à leur environnement dans les aires protégées se veulent particuliers, avec des objectifs affichés d'une cohabitation visant une forme «d'harmonisation» entre la nature et les sociétés. La régulation juridique qui en découle provient davantage des gestionnaires extérieurs aux territoires considérés que des acteurs mêmes qui...
The new SPOT/Envisat direct receiving station (DRS) operating in Cayenne in the framework of the SEAS-Guyane project was used to produce a global cloudless SPOT mosaic over French Guiana for the year 2006. This mosaic was used to perform a land-use, land-use change and forestry (LULUCF) inventory in the framework of the Kyoto Protocol. Nearly 17 00...
Amazonia, main biodiversity reservoir on Earth, is at the heart of scientific and social debates focusing on sustainable management of natural resources. Brazilian and French teams working on this project selected several study sites in the Amazon Basin in function of spatial and temporal scales conditioning access to natural resources and biodiver...
In February of 2006, the SEAS GUYANE Platform was officially inaugurated at the IRD Centre in Caiena, French Guiana. This important techno-scientific facility is the fourth direct receiving station in South America, but the only one to receive orbital data from the Spot Constellation (2, 4, and 5) in continuous flows and from the Envisat Asar senso...
Hunting, although prohibited, is widely practiced by the rural inhabitants settled along the Transamazon highway. In 1997 and 2000, we investigated subsistence hunting in Uruar, a township located on an Amazonian pioneer front (Brazil). We analyze hunting practices, game yield, hunting efficiency and their relation to forest coverage rate. The hunt...
Cet article met en évidence la complémentarité entre les données optiques et les images radar pour la caractérisation et la cartographie des paysages urbains de l’île de Cayenne en Guyane française. Dans l’agglomération cayennaise les dynamiques d’urbanisation sont complexes et intenses. La télédétection permet de mieux les comprendre et les cartog...

On the Amazonian coast, cities grow at high rates and few data sets are available on urban dynamics, turning urban monitoring a challenging task. In this context, remote sensing is a powerful tool for socio-urban mapping. In order to extract relevant information from satellite imagery, we defined demographic density indices based on SPOT and LANDSA...
In the context of mandatory European regulations regarding natural resources and territorial management, the rural and agricultural institutions of the French Caribbeans and French Guiana need reliable and up to date geo-information. The PARAGE Consortium (SpotImage, IRD, CIRAD and SIGbea) gathers operational means and scientific know-how to addres...
