Available in PDF, EPUB and Kindle. Book excerpt: L'AUGMENTATION RAPIDE DANS LA TROPOSPHERE DE LA CONCENTRATION D'OXYDES D'AZOTE (NO ET NO 2), DU MONOXYDE DE CARBONE (CO), DU METHANE (CH 4) ET DES HYDROCARBURES A MONTRE L'IMPORTANCE DE L'IMPACT DES SOURCES ANTHROPIQUES SUR LES EMISSIONS DE POLLUANTS. LA DECOMPOSITION CHIMIQUE DES POLLUANTS PRIMAIRES EMIS CONDUIT ALORS A LA FORMATION D'ESPECES SECONDAIRES QUI PERTURBENT LES EQUILIBRES PHYSICO-CHIMIQUES DE L'ATMOSPHERE. LA MODELISATION DE LA QUALITE DE L'AIR A L'ECHELLE REGIONALE REQUIERT L'UTILISATION DE MODELES QUI PERMETTENT DE GENERER LES CHAMPS CLIMATOLOGIQUES (TEMPERATURES, VENTS, ETC.) AINSI QUE LES CHAMPS DE CONCENTRATIONS EN POLLUANTS. POUR CE TYPE DE MODELISATION, IL EST NECESSAIRE DE CONSTITUER DES INVENTAIRES D'EMISSIONS QUI PERMETTRONT D'ALIMENTER LES MECANISMES CHIMIQUES DU MODELE. CE TRAVAIL S'EST SURTOUT INTERESSE AU CYCLE DE FORMATION-DESTRUCTION DE L'OZONE TROPOSPHERIQUE ET A CHERCHE A ANALYSER LES PHENOMENES DE POLLUTION QUI SONT ETROITEMENT COUPLES AUX PARAMETRES CLIMATOLOGIQUES, AINSI QU'A L'INFLUENCE DES INVENTAIRES D'EMISSIONS. NOUS AVONS EFFECTUE DES SIMULATIONS SUR LA REGION REKLIP A L'AIDE DU MODELE EZM ET DES INVENTAIRES D'EMISSIONS HORAIRES POUR LA JOURNEE DU 16 SEPTEMBRE 1992. CES SIMULATIONS ONT PERMIS DE COMPRENDRE LA DYNAMIQUE DE LA COUCHE LIMITE ATMOSPHERIQUE ET D'OBTENIR LES CONDITIONS AUX LIMITES DE LA ZONE DE STRASBOURG. L'INVENTAIRE ANNUEL D'EMISSIONS POUR LA REGION DE STRASBOURG A ETE ACTUALISE POUR 1995, EN INCLUANT DES NOUVELLES SOURCES D'EMISSIONS PAR RAPPORT AUX PRECEDENTS INVENTAIRES. NOUS AVONS REALISE DES INVENTAIRES HORAIRES POUR STRASBOURG POUR LA PERIODE DE 8 AU 15 MAI 1998 (EPISODES DE FORTE POLLUTION) POUR ENSUITE EFFECTUER LA MODELISATION. UN TRAVAIL SIMILAIRE A ETE EFFECTUE POUR LA REGION COTIERE DE CASABLANCA (MAROC- JUILLET 1996). ENFIN NOUS AVONS REALISE DES ETUDES DE SENSIBILITE A L'AIDE DES INVENTAIRES D'EMISSIONS POUR VOIR L'INFLUENCE DES EMISSIONS SUR LES CONCENTRATIONS D'OZONE. CE TRAVAIL A APPORTE DES INFORMATIONS NOUVELLES SUR LA METHODOLOGIE LIEE A L'ELABORATION DES INVENTAIRES D'EMISSIONS ET A MIS EN EVIDENCE L'INFLUENCE DES PARAMETRES METEOROLOGIQUES SUR LES PHENOMENES DE POLLUTION DANS DEUX REGIONS D'ETUDE POUR PERMETTRE UNE MEILLEURE COMPREHENSION DE LA POLLUTION TROPOSPHERIQUE, A L'ECHELLE URBAINE NOTAMMENT.

Book excerpt: CETTE ETUDE CONCERNE UNE ANALYSE SPATIO-TEMPORELLE DE LA DISPERSION DES POLLUANTS ATMOSPHERIQUES EN ZONE URBAINE. LES OUTILS D'ANALYSE DEVELOPPES ONT ETE APPLIQUES AUX CONCENTRATIONS HORAIRES DE SO#2 ET DE NO#2 MESUREES PAR AIRPARIF SUR LA PERIODE 93-97. L'ANALYSE TEMPORELLE A MIS EN EVIDENCE LE CARACTERE NON-HOMOGENE DE LA DISTRIBUTION SPATIALE DE LA POLLUTION ET L'INFLUENCE DES ACTIVITES HUMAINES. POUR LE CALCUL DES CHAMPS DE CONCENTRATIONS DE POLLUANTS, UNE METHODE D'INTERPOLATION BASEE SUR LES FONCTIONS SPLINE PLAQUE MINCE A ETE DEVELOPPEE. LA METHODE A ETE VALIDEE POUR LE CAS D'AIRPARIF ; LA QUALITE DE L'INTERPOLATION DEPEND DE LA DENSITE ET DE LA DISTRIBUTION SPATIALE DES STATIONS. LA CARTOGRAPHIE DES CHAMPS DE CONCENTRATION CONFIRME LEUR CARACTERE NON-HOMOGENE, PLUS ACCENTUE PENDANT LES PERIODES DE FORTE POLLUTION ET OUVRE DES PERSPECTIVES POUR L'OPTIMISATION DES RESEAUX. L'ANALYSE D'UN GRAND NOMBRE DE DISTRIBUTIONS SPATIALES ETANT DIFFICILE, ON A PROCEDE A LA CLASSIFICATION DES CHAMPS DE CONCENTRATION, AFIN DE RESUMER TOUTES CES INFORMATIONS PAR UN NOMBRE LIMITE DE TYPOLOGIES. CETTE CLASSIFICATION, APPLIQUEE AUX EPISODES DE POLLUTION, A PERMIS DE CARACTERISER CHAQUE REPARTITION SPATIALE PAR UNE TYPOLOGIE ET UNE MOYENNE. L'ANALYSE DES TYPOLOGIES MONTRE LA CORRESPONDANCE ENTRE ZONES FORTEMENT POLLUEES ET ZONES INDUSTRIELLES. LA DISTRIBUTION DE LA POLLUTION DEPEND AUSSI FORTEMENT DES VENTS. POUR UNE MEILLEURE COMPREHENSION DE LA DISPERSION PENDANT LES EPISODES DE POLLUTION, ON A PROCEDE A UNE ANALYSE STATISTIQUE DESCRIPTIVE, QUI A PERMIS D'IDENTIFIER DES PARAMETRES METEOROLOGIQUES FAVORISANT L'ACCUMULATION DES POLLUANTS. FINALEMENT, CETTE ANALYSE PERMET DE DEFINIR LES ENTREES-SORTIES D'UN MODELE BOITE NOIRE, RELIANT UNE TYPOLOGIE DE LA POLLUTION ET SA MOYENNE A L'INSTANT T+1 AUX MEMES PARAMETRES AUX INSTANTS ANTERIEURS ET A LA SITUATION METEOROLOGIQUE A L'INSTANT T. CETTE DEMARCHE, BASEE SUR UNE APPROCHE RESEAU DE NEURONES, OUVRE DE NOUVELLES PERSPECTIVES DE RECHERCHE.

Book excerpt: An Environmental Impact Assessments (EIA) is a procedure for evaluating the impact of proposed activities on the environment. In modern Africa, EIAs are a growing reality and a matter of law in 22 sub-Saharan African countries. This volume examines various aspects of EIA legislation in these countries, including: definitions and prescribed activities; public participation and consultation; the review process and the quality of EIA reports; monitoring and enforcement; compatibility; and transboundary issues. It highlights the role and degree of public participation for the further development of EIA law and policy.
Download or read book The Mediterranean region under climate change written by Collectif and published by IRD Éditions. This book was released on 2018-11-19 with total page 736 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has been published by Allenvi (French National Alliance for Environmental Research) to coincide with the 22nd Conference of Parties to the United Nations Framework Convention on Climate Change (COP22) in Marrakesh. It is the outcome of work by academic researchers on both sides of the Mediterranean and provides a remarkable scientific review of the mechanisms of climate change and its impacts on the environment, the economy, health and Mediterranean societies. It will also be valuable in developing responses that draw on “scientific evidence” to address the issues of adaptation, resource conservation, solutions and risk prevention. Reflecting the full complexity of the Mediterranean environment, the book is a major scientific contribution to the climate issue, where various scientific considerations converge to break down the boundaries between disciplines.
Download or read book An Introduction to the African Convention on the Conservation of Nature and Natural Resources written by World Conservation Union and published by IUCN. This book was released on 2009 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: The African Convention on the conservation of nature and natural resources was adopted in 1968 in Algiers. Considered the most forward looking regional agreement of the time, it influenced significantly the development of environmental law in Africa. Two and a half decades of intense developments in international environmental law made it necessary to revise this treaty, update its provisions and enlarge its scope. This was undertaken under the auspices of the African Union (previously OAU), and the revision was adopted by its Heads of State and Government in July 2003 in Maputo. The introduction provides an overview of this new international treaty, as well as a commentary to each of its provisions.

Download or read book Relict Species written by Jan Christian Habel and published by Springer Science & Business Media. This book was released on 2009-12-03 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mankind has evolved both genetically and culturally to become a most successful and dominant species. But we are now so numerous and our technology is so p- erful that we are having major effects on the planet, its environment, and the b- sphere. For some years prophets have warned of the possible detrimental consequences of our activities, such as pollution, deforestation, and overfishing, and recently it has become clear that we are even changing the atmosphere (e. g. ozone, carbon dioxide). This is worrying since the planet’s life systems are involved and dependent on its functioning. Current climate change – global w arming – is one recognised consequence of this larger problem. To face this major challenge, we will need the research and advice of many disciplines – Physics, Chemistry, Earth Sciences, Biology, and Sociology – and particularly the commitment of wise politicians such as US Senator Al Gore. An important aspect of this global problem that has been researched for several decades is the loss of species and the impoverishment of our ecosystems, and hence their ability to sustain themselves, and more particularly us! Through evolutionary time new species have been generated and some have gone extinct. Such extinction and regeneration are moulded by changes in the earth’s crust, atmosphere, and resultant climate. Some extinctions have been massive, particularly those asso- ated with catastrophic meteoric impacts like the end of the Cretaceous Period 65Mya.
Download or read book Heritage Sites of Astronomy and Archaeoastronomy in the Context of the UNESCO World Heritage Convention written by Clive L. N. Ruggles and published by Ocarina Books. This book was released on 2012 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Thematic Study is a joint venture between ICOMOS, the advisory body to UNESCO on cultural sites, and the International Astronomical Union. It presents an overall vision on astronomical heritage, attempts to identify what constitutes "outstanding universal significance to humankind" in relation to astronomy, and identifies broad issues that could arise in the assessment of cultural properties relating to astronomy. This is the first Thematic Study in any field of science heritage. It is elaborated using examples of properties from around the world, including some already on the World Heritage List or national Tentative Lists. The subject matter ranges from early prehistory to modern astrophysics and space heritage, and also prominently includes dark sky issues and modern observatory sites. An e-version of the Thematic Study was published in June 2010 in time to be presented to the 2010 meeting of UNESCO's World Heritage Committee, where it was duly approved. It has been circulated officially by the WHC to all of UNESCO's National Commissions. This full-colour paperback edition with some updates, and reformatted to new ICOMOS standards, was published in 2011 and is now offered for public sale.

Download or read book Water Heritage written by Willem Willems and published by . This book was released on 2017-01-15 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is vital for life, and its availability has been a concern for mankind throughout the ages. Its presence has always been ascertained in a variety of ways and the development of human society everywhere is connected with various forms of water management. Man also needed to manage water to find protection from its dangers and the need for that is increasing. In the coming decades, the impact of climate change is expected to intensify floods and droughts, affect groundwater resources, raise sea levels, increase pollution and enhance the frequency and magnitude of disasters. Societies around the world are challenged to adapt to these threats to ensure water security, economic prosperity and environmental and cultural sustainability. This book deals with the heritage of water management and the use that was made of water, as well as the impact of water management on heritage. An example of the former may be an ancient irrigation system in the Filipines or in the Middle East that still functions today, while the latter may reflect the importance of maintaining groundwater levels for the preservation of organic remains on archaeological sites or of wooden piles underneath standing buildings. In either case the papers in this book reflect the dynamic nature of water, and hence the equally dynamic relation between water management and heritage. This publication follows up on a Heritage and Water conference in Amsterdam, the first of its kind. Its main purpose is to credibly present the importance and value of heritage and historical experience for water and sustainable development, and vice versa, present the importance of water management for the protection of heritage. It presents evolving insights and concepts about Water and about Heritage from a variety of disciplines, policy and public perspectives illustrated with cases studies and aims to connect decision makers with experts such as engineers, archaeologists, historians, geographers, ecologist and landscape architects
