Land Based Activities and Sources of Pollution to the Marine, Coastal and Associated Fresh Water Ecosystems in the Western Indian Ocean Region
The lack of infrastructure and treatment facilities for the large quantities of domestic sewage generated by expanding coastal urban populations, and an increasing number of visiting tourists, represents the greatest threat to public health, coastal habitats and economic development in each state of the region. Other priorities requiring action include the effects of siltation related to agricultural activity and the dumping of solid domestic waste in the coastal areas leading to the degradation of coastal habitats, with implications for fish stocks and catches. Furthermore, laws and policies regardinng waste disposal and quality of effluents need to be enacted and reinforced Although eutrophication and algal blooms associated with agricultural, industrial or domestic sewage pollution have been identified as a threat to coastal habitats, further scientific research is required to link the causes and effects. Monitoring programmes need to be initiated in the region in order to mitigate .....
