Eutrophication is the enrichment of nutrients in aquatic environment (organic matter increase in water), is an ongoing problem in coastal marine and freshwaters worldwide. The large loading of N and P stimulates the growth of phytoplankton, microalgae and microbial populations and processes which says the undesirable disturbance to the balance of organisms, ultimately photosynthesis exceeds respiration. On the other hand, decomposition of the greater supply of organic matter microbial populations often result in depletion of dissolved oxygen (anoxia and hypoxia: oxygen concentration > 2 ppm) therefore, lead to an increase in marine N2O emission in stratified bottom water to levels, which is very low to sustain fishes and invertebrates.
The coral reef ecosystem, besides facing the above situations, also to experience rise in seawater temperature due to climate change. The increases in temperature besides causing bleaching also alter the metabolic processes, which may affect the health of the corals.
To develop an ecosystem model for coral reef areas in Lakshadweep to predict likely changes of health of coral reefs in the event of climate variability especially the rise in seawater temperature and increase in anthropogenic activities
