countries globally, and occurs mainly in the eastern coastal state of Andhra Pradesh (AP). More than 90% of the
farms are less than 2 ha and are farmer owned, operated and managed. The objective of this study was to
increase our understanding of climatic and socio-economic factors influencing this sector, through a survey of
300 shrimp farmers in AP in 2009/10. The farming communities were divisible into two groups: members of a
society/cooperative and those operating individually. The latter were large scale adopting more intensive
practices. The average production cost was Indian Rupees (IRS) 80,186 ha-1 and net income in summer and
winter was IRS 221,901 and IRS 141,715, respectively. The mean technical efficiency estimated using Stochastic
frontier function was 7% and 54%. The present study attempts to explain the difference in efficiencies using
socio-economic and climatic variables, the latter being a novel approach. Among socio-economic variables,
farming experience and membership in society were found to have a significant influence to improve technical
and economic efficiencies. Further improvements in identifiable facets of the practices and a consequent increase
in technical efficiency will make the sector less vulnerable to climatic change impacts.Not Availabl
