Unit                                           :     Ratio / Percentage

 

Definition                               :     Volume of rice produced locally as a percentage of total requirements for consumption

SSRR =

RAL

X 100

TR

 

 
 


Method of computation   :

                                                   

                                                   

RAL =

Total production of paddy – (Seeds requirement + Post harvest loses)

X 68

100

 

 

TR  =

Mid-year population X PCC

 

 
 

 

 

 

 

 

 


                                                                                    SSRR: Self Sufficiency Rate of Rice

                                                                                    RAL: Rice availability from local source

                                                                                    TR: Total requirement of rice for a given year

                                                                                    PCC: Per capita consumption

 

 

 

Limitations                             :     Total requirement of rice is estimated as a product of mid-year population and estimated per capita consumption of rice.  Per capita consumption (PCC) is obtained based on the Household Income and Expenditure Survey (HIES) conducted by the Department of Census and Statistics (DCS) ad-hoc basis.  As such factors influencing to consumption are treated as constant.
