CASE STUDY- Coastal management (Odisha) Flashcards
Where is the Odisha coastline located?
Located in the North east of India, bordering West Bengal.
What are the landforms that are found at Odisha’s coastline?
Has 6 major deltas, which are a source of sediment.
Chilika lake is a salty lagoon, during monsoon season the saline level drops due to the volume of rainwater and the lake spreads.
This lake is an important water store.
What coastal erosion occurs along the coastline?
Erosion in some areas provides input of sediment further down the coast.
Erosion varies throughout the year as there is less material removed during the Summer and there is more accretion. Whereas in the Winter, erosion rates are higher.
What are the concerns associated with the coastline?
There is a highly dense population on this coastline. There are high levels of flooding, tsunamis and climate change. Therefore in 2011, there was a plan formed to tackle these issues and threats.
Why is the coastline at risk of cyclones?
This coastline sits on the Bay of Bengal, which is a high risk zone for such events.
What is one example of a cyclone that impacted Odisha?
Cyclone Phailin (2013)
displaced over a million people
44 deaths
over 500,000 hectares of farmland destroyed.
$700,000 in damage.
What was the results of the 2013 coastline report?
The coast is mostly accreting, 36% erosion, 14% stable.
Most accretion occurs in the North near deltas.
Most erosion occurs in the South, coastal defenses have interfered with natural processes increasing rates of erosion.
Bhadrak has dense mangrove forests where accretion rates are 50% higher.
What does the Integrated Coastal Zone Management (ICZM) involve?
Establish sustainable social and economic activity.
Find solutions for the social, economic and environmental issues.
Protect the coastline.
How is the Odisha coastline being protected?
Large projects and small projects have taken place. Local people have been encouraged to consider natural coastal defences - mangroves, eco-tourism, building cyclone shelters. Greenpeace has tried to include village views in the ICZM.
What are the human opportunities?
Fishing and agriculture
Tourism on the beaches
35% of the coast is laden with minerals, such as limestone and clay.
How much of the region is taken up by mangrove forest?
Approximately 1440km.
