4.1 NUTRIENT CYCLES

Among the most productive ecosystems in the biosphere, coastal lagoons cover 13%
of world's coastal zone 1 and constitute an interface between terrestrial and marine
environments. 2,3 Nutrient loadings coming from both boundaries to lagoon ecosys-
tems have increased considerably in recent years, and they have a major impact on
