ObjectiveObjective

• Basis for the communication and exchange of ideas

• To encourage development in the most suitable areas

• To define areas to promote the development

• To provide a focus for research or monitoring

• To define environmental capacity • To develop area-based certification• Basis for sectoral EIA or Cost Benefit

MethodologyMethodology• The required criteria for the

objectives have been considered during the Remote Sensing and GIS analysis.

• The diagnostic factors considered for suitability assessment for different vital activities depending on their respective parameters

• The land suitability map was prepared to identify the suitable area for each activity

MangroveMangrove

• The swamp consisted of innumerable low-lying islands, which were mostly submerged at high tide

• Responsible factors: Removal of forest product for fuel, shrimp farming, human settlement, salt production……………

Activity

Reserved Mangrove forest

Allowed human settlement

Human settlement expanded

Shrimp and salt encroachment

The entire mangrove forest altered in shrimp farms with minor salt bed and human settlementTable:Historical changes of Chokoria Sunderban mangrove forest
