Coastal areas and inland water bodies , salt marshes have their own flora and fauna. High tides and low tides have their role to play. During monsoon season rain water allows the growth of certain halophytes as their seeds require non saline water for their germination while they need saline water for their growth. Salicornia is one such plant. Rhizophora with its special pneumatophores meant for gaseous exchange is another plant of coastal marshes. Different algal material also grows in the coastal waters depending on the ocean Once the plants are there the sea animals get their food and a sort of ecosystem based on saline water , rain water, salt marshes, sandy beaches develop in which flora and fauna supports each other. Trees like Casurina the non leguminous nitrogen fixing tree which fixes nitrogen using Frankia is commonly found on coastal areas. Coconuts trees make the coast line of Kerala in India. A balance has to be there to support the coastal ecosystem. Some integrated development projects are needed to be taken up at global level. The effect of future Tsunami has to be mitigated. World has to live now with threats of Tsunamis which will be increasing in ferocity with passage of time due to rising temperatures and climate change phenomenon getting faster and faster. It’s a very sorry state of affairs that people of coastal regions suffer again and again. Our deep sympathies with all people and wishes for quick recoveries should also be based on future protective measures. However I would suggest some bio based solutions for development of coastal areas to protect populations and installations from raising sea water and effects of climate change. There is urgent need to mitigate climate change effects. 40 percent of the world’s population lives in coastal areas.
