Book Description
LES CONTINENTS AFRICAIN, SUD-AMERICAIN ET ASIATIQUE PRESENTENT UN DEFICIT IMPORTANT EN CARTES A MOYENNES ET GRANDES ECHELLES (1/200 000 ET 1/50 000). DE PLUS, L'APPARITION DE L'IMAGE NUMERIQUE, ET EN PARTICULIER DES IMAGES ACQUISES PAR LES SATELLITES RADAR, A DONNE NAISSANCE A UN NOUVEAU TYPE DE PRODUIT CARTOGRAPHIQUE, LA SPATIOCARTE RADAR. CE PRODUIT SEMBLE LE MOYEN LE PLUS ADAPTE POUR COMBLER LE DEFICIT EN CARTOGRAPHIE TRADITIONNELLE (CARTES AU TRAIT) DES REGIONS TROPICALES. EN OUTRE, LES CAPTEURS RADAR QUI EQUIPENT LES SATELLITES ERS 1/2, JERS ET LE TOUT RECENT RADARSAT PRESENTENT DES APTITUDES PROPRES QUI LEURS CONFERENT CERTAINS AVANTAGES SUR L'OBSERVATION OPTIQUE. LA PREMIERE PARTIE DE CE TRAVAIL CARACTERISE LE BESOIN CARTOGRAPHIQUE EN MILIEU TROPICAL ET SE DIVISE EN DEUX TEMPS. TOUT D'ABORD, IL EST MONTRE COMMENT UNE CARTE TOPOGRAPHIQUE CLASSIQUE SE DECLINE EN UNE SERIE DE FONCTIONS CARTOGRAPHIQUES SATISFAISANT DES CONTRAINTES QUALITES LIEES A LA GEOMETRIE, LA SEMANTIQUE, L'ACTUALITE ET L'ERGONOMIE DE LA CARTE. ENSUITE, L'ETUDE SUR LA NATURE DES UTILISATEURS DE PRODUITS CARTOGRAPHIQUES EN MILIEU TROPICAL AINSI QUE LA DEFINITION DE LEURS BESOINS PERMET DE DEFINIR UNE GAMME DE PRODUITS PERMETTANT DE SATISFAIRE LE PLUS GRAND NOMBRE. DANS LA SECONDE PARTIE DE CETTE THESE, L'ETUDE PORTE SUR LES DIFFERENTES ETAPES D'UNE FILIERE DE PRODUCTION CARTOGRAPHIQUE A BASE D'IMAGES R.S.O. EN AMPLITUDE. DANS CE CADRE, IL EST MONTRE COMMENT LE CHOIX DES DONNEES SOURCES ET L'ORGANISATION DES TRAITEMENTS PERMETTENT D'INTEGRER LES CONTRAINTES LIEES AUX DONNEES R.S.O., AUX TECHNIQUES MISE EN UVRE ET AU CONTEXTE D'APPLICATION, EN VUE DE LA SATISFACTION OPTIMALE DU BESOIN. DANS LA TROISIEME PARTIE, DE NOUVEAUX TRAITEMENTS SONT MIS EN UVRE POUR AMELIORER LA QUALITE DES IMAGES R.S.O. A DES FINS D'UTILISATIONS CARTOGRAPHIQUES : LE FILTRAGE MULTIDATES ET LA REDUCTION DE LA DYNAMIQUE (TRANSFORMATION 16 BITS / 8 BITS) DES IMAGES R.S.O. LA DERNIERE PARTIE VISE A CARTOGRAPHIER L'OCCUPATION DU SOL SUR UNE ZONE COTIERE SITUEE AU SENEGAL A L'AIDE DES CAPTEURS ERS-1, JERS, RADARSAT ET LANDSAT TM. CELA PERMET PAR LA SUITE DE METTRE EN AVANT L'APPORT RESPECTIF DE CHAQUE SATELLITE POUR LA CARTOGRAPHIE DU SENEGAL ET DE CONSTRUIRE UNE METHODOLOGIE D'EXPLOITATION OPERATIONNELLE DES DONNEES RADAR A DES FINS CARTOGRAPHIQUES EN MILIEU TROPICAL

Book Description
The novel coronavirus SARS-CoV-2, which causes the disease known as COVID-19, has infected people in 212 countries so far and on every continent except Antarctica. Vast changes to our home lives, social interactions, government functioning and relations between countries have swept the world in a few months and are difficult to hold in one’s mind at one time. That is why a collaborative effort such as this edited, multidisciplinary collection is needed. This book confronts the vulnerabilities and interconnectedness made visible by the pandemic and its consequences, along with the legal, ethical and policy responses. These include vulnerabilities for people who have been harmed or will be harmed by the virus directly and those harmed by measures taken to slow its relentless march; vulnerabilities exposed in our institutions, governance and legal structures; and vulnerabilities in other countries and at the global level where persistent injustices harm us all. Hopefully, COVID-19 will forces us to deeply reflect on how we govern and our policy priorities; to focus preparedness, precaution, and recovery to include all, not just some. Published in English with some chapters in French.

Book Description
One million dead a Wear, 500 million with the disease, 2.5 billion people at risk : this is the malaria balance sheet in 2007. The distribution and seriousness of the disease depend on the pathogens and vectors involved, as welt as environmental conditions. Of the four parasites (Plasmodium), only P. falciparum kilts although the other three cause debilitating disease with regular relapses and recrudescence. More than fifty species of Anopheles can fulfil the vector rote which is essential in transmission of the parasite between human beings. Climatic factors (temperature and rainfall), the environment and biogeographical particularities dictate the distribution of anopheline species and determine transmission rates. This is why it makes sense to tank about the biodiversity of malaria. Today, more than 90% of deaths from malaria occur in Tropical Africa which is home to only 10% of humanity. Every 30 seconds a child dies from malaria. This continent harbours the most effective vectors (An. gambiae and An. funestus, in particular) and the climate is highly conducive to transmission of the disease. Severe malaria is also seen in forest foci in Southeast Asia, Papua-New Guinea and the Amazon. In the rest of the tropical and subtropical world, P. vivax and/or P malariae cause less severe disease.

Book Description
New and innovative scientific theories, discussion and explanations are presented on landform dynamics and evolution in Romania along with a comprehensive understanding of the geomorphological processes shaping the large variety of Romania’s landscape. Thematically arranged the book deals with landform dynamics of specific relief types: glacial and periglacial, denudational, fluvio-denudational, fluvial, karst and coasts, as well as sediment fluxes, geomorphic hazards and risks. The authors are key scientists and researchers in the field and offer innovative views on research methods and concepts applied to the topics in question. This work will be of interest to students and researchers in geography, geomorphology, geology, environmental science, paleoclimatology and soil science as well as policy and decision-makers in spatial planning.

Book Description
The term 'terrestrial carbon' refers to carbon contained in vegetation or soil stocks. The global carbon cycle plays an important role in sustaining agricultural productivity, biodiversity and forest ecosystems processes. This report presents the results of a workshop, held in Canada in February 2000 and organised by the Global Terrestrial Observing System (GTOS) in collaboration with the International Geosphere-Biosphere Programme (IGBP). The workshop was designed to review existing data and observation requirements regarding terrestrial carbon, identify major gaps and propose solutions.

Book Description
This volume provides a comprehensive perspective on geomorphic approaches to management of lowland alluvial rivers in North America and Europe. Many lowland rivers have been heavily managed for flood control and navigation for decades or centuries, resulting in engineered channels and embanked floodplains with substantially altered sediment loads and geomorphic processes. Over the past decade, floodplain management of many lowland rivers has taken on new importance because of concerns about the potential for global environmental change to alter floodplain processes, necessitating revised management strategies that minimize flood risk while enhancing environmental attributes of floodplains influenced by local embankments and upstream dams. Recognition of the failure of old perspectives on river management and the need to enhance environmental sustainability has stimulated a new approach to river management. The manner that river restoration and integrated management are implemented, however, requires a case study approach that takes into account the impact of historic human impacts to the system, especially engineering. The river basins examined in this volume provide a representative coverage of the drainage of North America and Europe, taking into account a range of climatic and physiographic provinces. They include the 1) Sacramento (California, USA), 2) San Joaquin (California), 3) Missouri (Missouri, USA), 4) Red (Manitoba, Canada and Minnesota, USA), 5) Mississippi (Louisiana, USA), 6) Kissimmee (Florida, USA), 7) Ebro (Spain), 8) Rhone (France), 9) Rhine (Netherlands), 10) Danube (Romania), and 11) Volga (Russian Federation) Rivers. The case studies covered in these chapters span a range of fluvial modes of adjustment, including sediment, channel, hydrologic regime, floodplains, as well as ecosystem and environmental associations.
