2011 assessment of shoreline change

2011 assessment of shoreline change

• most erosion in the south

• Bhadrak mangrove forests = 50% higher rate of accretion

• 14% stable

• coastline is mainly accreting (esp in the north)

south

where does most erosion occur?

accretion - especially in the north

opportunities of human development

• large fish stocks - aquaculture

• offshore wind and tidal power developments

• heavy metal and mineral deposits along 35% of coastline

• offshore oil and gas sea mining

• cultural sites

  • tourism

  • beaches

  • wildlife sanctuaries

risks of human developments

• seasonal variation

• attempts to halt erosion has pushed problem downstream

• vulnerable coastline communities

• rate of erosion

• tropical cyclones

seasonal variation in the summer

• accretion

• low energy coastline

seasonal variation in the winter

• erosion

• high energy coastline

attempts to halt erosion has pushed problem downstream

threatens barrier beaches and estuaries

vulnerable coastline communities

• storm surges

• concerned government

• flooding

• climate change

rate of erosion

increased due to human activity

how human intervention affects dynamic coastline

• concerns of economic value

• unnatural imbalance of erosion and accretion

tropical cyclone risks

• uproot power lines and trees

• destroy and disrupt livelihoods = constant cycle of resilience and adaptation

• increased vulnerability

• damaged ecosystems
