Agricultural vulnerability to climate change is the function of characteristics of climate variability, magnitude, and rate of variation within the agricultural system, and the systems sensitivity and adaptive capacity, and it is the degree to which the agricultural system is susceptible to, or unable to cope with adverse effects of climate change including climatic variability and extreme events.
The objective of the study was to assess the agricultural vulnerability of the Mahanadi Delta with respect to climate change.
Extent 85o40'E 86o45'E20o35'N

Five districts have been taken based on the intersection of bebelow 5 m elevation zone
Mahanadi Delta is one of the largest deltas on the east coast of India.
Climate: Tropical with hot humid monsoon

Flood plays major role in agricultural vulnerability of the Delta.Proper flood management may reduce the susceptibility of agriculture to vulnerability.
The most vulnerable block has been assed to be Delanga followed by Pipili and Astaranga block. Bhubneswar has been assed to be one of the least vulnerable block of the Delta
