313th EUMETSAT User Forum in Africa: Session #6 ‐Marine ApplicationsSeptember 27, 2018
The Mauritius Oceanography Institute (MOI), was established in January 2000 by the proclamation of the MOI Act (Act No. 24 of 1999). The need to rationalise and co‐ordinate research and development activities related to Oceanography was the motive for the setting up of the MOI.
Acronym of the name of the Leader
The Main Challenges facing the Indian Ocean and Eastern African countries:
• Fisheries management,
• Monitoring and control of illegal fishing,
• Climate change impact monitoring
• Better understanding of marine and coastal ecosystems
• Forecasting of extreme weather events
• Oil and Chemical pollution
• Coastal Zone management and beach erosion
• Harmful Algal Blooms

Overall Objective:
To promote a more sustainable management of marine and coastal resources by improving decision making process through provision of additional pertinent information to mandated institutions in the East Africa region.
Specific objectives:
• To provide an improved and sustained access to Earth Observation (EO) and in-situ data to stakeholders of East Africa countries.
• To consolidate and develop applications for the Marine and Coastal Areas Services to adequately provide information to policymakers, scientists, businesses and the public.
• To develop a framework for promoting intra-African collaboration and open access to data for the Marine and Coastal Areas Services.
• To contribute to the implementation of the “African Space Policy and Strategy”, in particular on Earth Observation.• To strengthen capacities of national and regional institutions to generate and apply EO-based and in-situ information for
the Marine and Coastal Areas Services.• To raise public awareness
