Tanzania

Tanzania has actively participated in ODINAFRICA since the pilot project phase and continues to do so in ODINAFRICA-III which has a broader focus aimed at serving stakeholders. Tanzania is represented in ODINAFRICA by the Institute of Marine Sciences which is a unit of the University of Dar es Salaam. The Institute of Marine Sciences was nominated by the government of Tanzania to be the Designated National Agency (DNA) in 1996 and in December 2002 its status was upgraded to full National Ocean-ographic Data Centre (NODC) commonly known as TzNODC.

In ODINAFRICA-III, The TzNODC has consolidated on the achievements attained in previous phases of ODIN-AFRICA to strengthen the management of ocean data and information at national level. With regard to this two major achievements were recorded:

(i) The TzNODC managed to revive the National IOC committee which is comprised of all nation-al stakeholders in ocean and coastal issues and related. This Committee was not active since early 80s.

(ii) A body that is charged to monitor and guide the functioning of the TzNODC has been cre-ated. This body, known as the National Ocean-ographic Committee (NOC) comprises of seven members from key stakeholder institutions who are member of the National IOC Committee. The TzNODC is the secretariat of the NOC

NATIONAL NETWORKING

The TzNODC has been working hard to establish linkages at national level amongst relevant stake-holders, i.e., institutions, projects etc. The previous-ly mentioned successes are results and testimony to these efforts.

These efforts are very much in line with ODINAF-RICA-III which has been expanded to included In-tegrated Coastal Area Management (ICAM) as well as Coastal Observing activities. At national level, the linkage between the ICAM community and the TzNODC is one of the most successful working re-lationships.

National networking is implemented in various ways including ensuring efficient and timely communi-cation, organizing relevant national stakeholders’ meetings/workshops/consultations, provision of good and relevant services as well as data and in-formation products.

PRODUCTS AND SERVICES

Through ODINAFRICA and IOC/UNESCO the TzNODC has received a lot of different data sets from various World Data Centres. These include:- GEBCO ATLAS (CENTENARY EDITION)- ETOPO2- TOGA data- Core data from Deep Sea Drilling project- Marine geophysical tracklines data- World Ocean Database 2001- and many others

These data are playing a key role in supporting ocean and coastal research and planning in Tanzania.

Furthermore, the TzNODC has extracted some of these data into simple formats mainly AISCII and excel (spread sheet) for easy use by local scientists, and also has started to create/develop various prod-ucts to serve its stakeholders/client community. The products include (i) base-mapping products which include AISCII data sets in XYZ format of the (a) the Tanzania coastline (b) major islands of Tanzania (c) all islets etc. (d) bathymetry of the Tanzania EEZ.

There are also locally collected datasets which are mainly kept in a GIS database. These data are used in the production of many different products in form of GIS maps focusing on many different themes.

Another product is Data Summaries of the available datasets. One such product that was recently pub-lished is the Data Summary on “Seawater tempera-ture as well as macro-algal abundance and coral settlement data around Unguja (Zanzibar) island”.

Among other things, the Data Summary gives very informative figures that show trends such as (next colum, top):

Another major product of the TzNODC is its online meta-database which has a lot key information on the resources, their distribution and many others on the coastal and marine environments of Tanzania. The TzNODC Information Centre provides elec-tronic library catalogue searches as well as links to other electronic libraries.

The TzNODC continues to provide expert training to students as well as govern-ment and other stakeholder’s employees in database devel-opment and management,

and also training in webpage design and online service provision.

Sensibilité à l’érosion et à la pollution : protection et risques L’érosion côtière et la pollution marine sont les deux phénomènes majeurs dont les impacts font état de sensibilité très élevée des res-sources naturelles marines et côtières. La pollution atmosphérique fait état d’une situation qui n’est pas encore mesurée, mais la sensibilité de la population aux effets induits (maladies pulmonaires) augmente. La protection des segments de côte sensibles a été mise en place en 1988 ; le secteur Kpémé-Gumukopé comporte 7 épis et celui d’Aného est protégé par 5 épis et 1 brise lame ; des ouvrages en enroche-ment.

Répartition de la population L’accroissement naturel est de 2,4 % entre 1990-1998. L’explosion démographique, due à l’exode rural, particulièrement vers Lomé, justifie cette croissance. L’importance socio-économique de Lomé polarise une part importante de la population. Le déséquilibre en-tre centres urbains et ruraux est assez énorme. Il est lié à l’histoire et à la géographie de la zone, ouverte sur l’océan. La population est jeune : 47,9 % ont moins de 15 ans, 3,8 % ont plus de 65 ans. La répartition par sexe fait apparaître 48% d’hommes contre 52% de femmes.

Commerce et marchés : commerce intéri-eur, extérieur et secteur informelLe commerce intérieur est fondé sur les marchés qui se distinguent en fonction de leur importance (internationaux, interrégionaux, régionaux, locaux, etc.). Le commerce extérieur est caractérisé par une balance commerciale déficitaire illustrée par les importations et exportations de marchandises au port de Lomé. Les exporta-tions sont constitués par la vente du phosphate, du bois et du ci-ment. Le trafic portuaire d’importation concerne essentiellement les biens d’équipement, les produits pétroliers et les biens de con-sommation. Le secteur informel urbain représente plus de 50% du secteur privé et occupe 84% de la population active. Il est es-sentiellement concentré à Lomé. Les branches d’activités les plus représentées sont le commerce et la restauration (51%), les vête-ments et chaussures (11%).

Evolution des captures de pêcheEn zone côtière se pratiquent la pêche lagunaire et maritime artisa-nale et industrielle. La production de la pêche maritime représen-te 4% du PIB du secteur primaire. La pêche maritime artisanale connaît deux saisons : haute saison de juillet en octobre et basse saison de novembre en juin. La production maritime artisanale représente 70% de la production halieutique nationale.

La zone côtière du Togo Superficie côtière 1050 km2, ZEE 12450 km2. Les secteurs d’activités économiques et d’infrastructures de communication sont concen-trés à Lomé. La population de la région maritime était estimée à 2 664 000 habitants en 2005.

Relief et morphologie Plateau homogène de terre de barre, cordons sableux et système lagunaire. Les plateaux sont séparés par des axes hydrographiques dominant de 10 à 20m la plaine côtière, étroite de 50 à 3000 m. Elle surplombe le niveau de la mer de 5 m de hauteur. Les fonds marins sont assez plats, marqués par des vallées linéaires, témoins de sys-tème d’érosion fluviatile. Le beach-rock, sur la plage, est un héritage d’anciens niveaux marins.

Climat et océanographie côtièreDeux masses d’air : l’harmattan, de décembre à janvier et la mous-son, de juillet en septembre ; quatre saisons, pluvieuses et sèches alternées et un vent dominant SW-NE caractérisent le climat subé-quatorial. Deux courants sont observés : la dérive littorale W-E et le courant de Guinée au large.

Territorialité : préfectures, cantonsLa zone côtière est découpée en 5 préfectures ; subdivisées en can-tons. La structure urbaine est très déséquilibrée avec Lomé, la capi-tale, qui polarise toutes les petites villes environnantes, Aného, Vo-gan, Tsévié. L’extension incontrôlée des pôles urbains est matérialisée par un habitat hétérogène. Les infrastructures de communication se distinguent par le port en eau profonde et l’aéroport.

Ces produits cartographiques réalisés par le CNDO-TOGO constituent un appui aux orientations des politiques de gestion intégrée de la zone côtière. C’est un référentiel de l’espace marin et côtier qui met à la disposition des utilisateurs, un ensemble de repères significatifs de la réalité environnementale du littoral du Togo.

Faits environnementaux : érosion côtière et pollution marine L’érosion côtière, caractéristique de la dynamique de côte, est l’effet de la construction du port de Lomé. La façade ouest de la jetée se recharge en sédiment. L’impact du recul est évalué en moyenne à 6m/an sur 30km. Les dommages sont les pertes de terre et des in-frastructures routières. La zone côtière concentre plus de 90% des unités industrielles du pays. La pollution marine est la conséquence du déversement en mer des argiles et des eaux usées issues du traite-ment des phosphates.

Ressources minières La zone côtière est riche en sables et graviers. Leur exploitation se fait tout le long de la côte ; seules deux carrières sont autorisées à Lomé et Aného. Les volumes exploités avoisinent 10 000 m3/an. Les graviers de mer sont exploités sur la plage de façon artisanale par les populations rurales, essentiellement les femmes. C’est une activité de substitution à l’activité de pêche n’existant presque plus à l’est du port à cause de l’érosion côtière.

Couverture sanitaire La dégradation de l’état de santé des populations est observée depuis 1993. La démographie galopante et le manque d’entretien des infra-structures sanitaires existantes entraînent une surcharge des forma-tions sanitaires en particulier le CHU Tokoin, le plus important centre hospitalier de Lomé, où le taux d’accroissement du nombre de malade est de 73% entre 1997 et 2001. Beaucoup d’urbains font recours à la médecine traditionnelle, mais la volonté de contrôle de ce secteur est encore peu efficace. L’épidémiologie évolue aussi négativement ; le paludisme reste la première cause de morbidité. Le Sida, les maladies infectieuses et les maladies respiratoires viennent compléter la liste des endémies.

The toxic phytoplankton, chemical and organic pol-lutants database, consists of a Web-based tool data edition and consultation . Statistics tools were de-veloped for data-products consultation and a car-tographic interface illustrates the last sanitary po-sition of the studied zones. This tool can detect instantaneously the sanitary position of coastal ar-eas and permits, in some toxicity cases, to identify the responsible agent and to assess the geographic dispersion of a toxic event.
