Coastal ecosystem of Jamnagar district (Gujarat),is known for wide range of
activities, including port services, fisheries, tourist attraction and hosts a
number of large companies. But the ecosystem constraints crop production due to
severe climatic and edaphic limitations.Present study has been undertaken to
identify soil constraints by adopting physiography-soil series relationship.
The study revealed that
of the 10167 km2 inland area,
Jamnagar, Dhrol,Bhanwad and Kalawad soil series on nearly level basaltic plain
covering 31% area was free from constraints. Lalpur,Khambhaliya shallow and
Kalawad shallow soil developed on moderately undulating basaltic plain covering
20% area had severe
depth and water erosion constraints. Khambhaliya and Kalyanpur series on gently
sloping basaltic plain with moderate depth and water erosion constraints cover 17%
area. Okha series on nearly level limestone plain covering 3.2% area had
moderate depth constraints. Okha shallow series on gravelly uplands/stony
areas, and gravelly uplands spread through the district had severe depth constraints in
9% area. Inland saline, coastal saline and ranncovering
7.6% area are highly constrained due to high salt content. Mangroves and
mudflats and beaches and sand dunes occupy respectively 6.1 and 6.3 per cent
area.Management practices to overcome constraints and improve coastal ecosystem
have been suggested to control land degradation and maintain coastal arid
ecosystem
