Case study - Odisha coastline Flashcards
coasts
Location
Eastern coast of India boadring the bay of Benga.
How large is Odisha?
9th largest in India by state
11th largest by population
Physical landscape of odisha?
- Relatively straight coastline (480km long)
- A few natural harbours and inlets
- The odisha coastal plain (narrow level coastal strip) - supports the bull of the population
Why is odisha known as the Hexadeltaic region or the gift of six rivers?
Odisha has 6 deltas on the odisha coast
(
Odishas coastal landmaine
Has a wide variety of coastal and marine flora and fauna including mangroves, sea grasses and sun dunes. There are also large stocks of fish, marine animals, reptiles etc..
143km^3 of mangrove
Chilika lake
Blackish, salty lagoon, birdlife
During monsoons becomes less saline (diluted by fresh water, rainwater) becomes larger than it usually is
TEMPORARY STORE OF WATER IN THE WATER CYCLE!
Is odisha an important sediment store?
Yes!
The 6 deltas provide a source and sink of sediment for this part of the Bay of Bengal
Human opporunities in Odisha?
- Large stocks of fish
- Marine mammals
- Reptiles
- Huge potential for offshore wind,tidal and wave power
- 35% of the coastline is laden with minerals and heavy metal deposits
- Oil and natural gas offshore
- Tourism - beaches, wildlife, sanctuaries, archelogial sites
Risks for human occupation and development?
- Vulnerability of coastal communities due to storm surges, tsunamis, climate change and rising sea levels
- Majority of the states population living on coast caused a concern to indian government
Shoreline assessment in 2011
- Attempting to halt processess with sea walls and hard structures would mean the problems will shift down drift
- Without sediment transport beaches dunes barrier beach etc would be threatened and disapear as they are starved of sediment
Natural seasonal variations
Occur along the coast wiyj acceration occuronh in the summer during relatively low energy wave conditions and erosion in winter with high energy waves
How much of odishas coastline is eroding how much is stable?
36.8% eroding and 14.4% stable.
Odishas ICZM project
- Has co-ordinated the activities of various stakeholders and promoted the sustainable use of natural resources of the odisha coastline whilst maintaining the natural enviroment
Who are odishas stakeholders?
