What are the risks along the coastline?
excessive rate of erosion receding coastline - 3KM natural sand is block increased flooding -low lying area port- stopping natural flow of sediment
what threatens this coastline?
- construction of port
- port blocks natural flow of sand
- salt water has seeped into the fields
- 5-7 villiages lost
What has happened to this coastline?
it has receeded
people are having to move to areas which are already overcrowded
what are mangroves?
a sustainable coastal management
what are the goods available from a mangrove forest?
fuel -firewood and charcoal construction materials fishing materials household items food and drink textiles medicines
what are the services available from mangrove forests?
protection
provision
maintenance
value
what are the risks for human occupation and development?
- rates of erosion have increased greatly in recent decades
- majority of the population live on the coastal plain - vulnerable to storm surges and tsunamis
- attempting to halt natural processes shifts the problem downshore
- greater risk of erosion in winter due to destructive waves
what are the aims of the ICZM process along the odisha coastline?
it aims to:
- establish sustainable levels of economic and social activity
- resolve environmental, social and economic challenges and conflicts
- protect the coastal environment
how have they managed the delta?
- people are being trained
- construction of reservoirs has helped to reduce flooding
- built coastal flood shelters and having early warning systems
- regulation of motor boat traffic
- a bank of mangrove species has now been made on the delta
opportunities for human occupation and development?
- wide variety of marine coastal flaura and fauna
- large stocks of fish
- area has huge potential from offshore wind
- 35% of the coastal stretch is laden with substantial power
- there are opportunities for offshore oil and natural gas
- cultural and archaeological sites attract tourists
- tourism
- chilika lake bird sanctuary is home to over 150 species of birds
how is flooding a threat along this coastline?
eustatic sea level rise
storm surges
rivers discharging into the sea
how is erosion a threat along this coastline?
low lying
storm waves - indian ocean long fetch
how is human management of the coast a threat along this coastline?
lack of awareness by decision makers
what are the opportunities along this coastline as a whole?
flat land -easy to build on minerals and heavy metal deposits tourism opportunity-beaches and dunes flora and fauna renewable energy offshore oil and natural gas fishing / $12,000 archeological sites mangroves -defence can also create resources tourism - marine life
